Problems to be solved by the invention

In the above-described card game, it is desirable that a person other than the player also enjoy the battle, and in order to enable a larger number of persons or persons at a remote place to enjoy the battle, it is conceivable to realize a system in which an image showing the current state of the game field is displayed on a display unit for the spectator. As a configuration of such a system, the following configuration is considered: the system identifies the type and state (position, orientation, front and back sides, etc.) of a card placed in a game field, and displays an image showing the current situation on a display unit for the spectator based on the identification result. In this case, as a method for determining the type and state of the cards placed in the game field by the system, the following method is considered: an imaging unit for imaging a game field is provided, and the type and state of a card placed in the game field are determined based on an image captured by the imaging unit.

[ problem 1 ] there is a problem that it cannot be specified (or is difficult to specify) from a captured image. For example, although it is relatively easy to specify the position, orientation, and the like of the card from the captured image, the type of the card may not be specified (or may be difficult to specify).

For example, in a card used for a card game, a text or a pattern corresponding to the type of the card is generally recorded on the front surface, and a common text or a common pattern, which is not related to the type of the card, is recorded on the rear surface. In the card game, the card may be placed on the game field in a state where the front and back surfaces thereof are turned upside down in a regular manner, but in such a case, the front surface of the card is not captured in the captured image, and therefore, the type of the card cannot be specified from the captured image.

Further, for example, it may be difficult to specify the type and state of a card placed on a game field from a captured image due to the influence of ambient light or the like. There are also many kinds of cards used in card games, which are subjected to special processing (e.g., holograms, etc.), and it is difficult to specify the type and state of the card from a captured image.

[ 2 ] generally, a card used in a card game has a front surface on which a text or a pattern corresponding to the type of the card is recorded, and a rear surface on which a common text or a pattern, or the like, is recorded regardless of the type of the card. In the card game, the player may place the card on the game field in a state where the front and back sides are reversed in a regular manner, but in this case, even if the spectator wants to know the kind of the card (the front description content) placed in a state where the front and back sides are reversed, the spectator cannot know the kind of the card (the front description content) until the card is directed to the front side as in the player of the opponent, and the spectator may feel the interest in the battle insufficiently.

[ problem ] to determine the type and state of a card placed in a game field by a system, it is conceivable to adopt the following method: a method for setting a shooting part for shooting a game field and determining the type or state of a card placed in the game field according to a shooting image of the shooting part. However, the type and state of the card placed in the game field may not be specified (or may be difficult to specify) from the captured image.

For example, in general, in a card used for a card game, since the front surface has an appearance corresponding to the kind of the card and the rear surface has a common appearance regardless of the kind of the card, when the kind of the card placed in a game field is determined from a captured image, the kind of the card is determined from the front surface of the card captured in the captured image. However, in the rules of the card game, the card may be placed on the game field with the front and back surfaces thereof turned upside down, and in such a case, the front surface of the card is not captured in the captured image, and therefore, the type of the card cannot be specified from the captured image.

Further, for example, it may be difficult to specify the type and state of a card placed on a game field from a captured image due to the influence of ambient light or the like. There are many kinds of cards used for card games, which are subjected to special processing (e.g., holograms, etc.), and it is difficult to specify the type and state of the card from a captured image.

In addition, in order to be able to specify (or easily specify) the type and state of a card placed in a game field, it is also conceivable to provide a special mechanism for this purpose in the card itself, but in this case, there arises a problem that an existing card (a card not provided with the mechanism) cannot be used in a game.

An aspect of the present invention has been made in view of the above-described problem 1, and an object of the present invention is to provide a specifying system, a specifying device, a program, and a specifying method that can specify (or easily specify) the type and state of a real object placed on an object surface in the real world.

An aspect of the present invention is made in view of the above-described problem 2, and an object of the present invention is to provide a display control system, a display control device, a program, and a display control method that can increase the interest of a viewer in viewing a game played using a real object placed on an object plane set in the real world, for example.

In addition, an aspect of the present invention has been made in view of the above-described problem 3, and an object thereof is to provide a container and an object that can use an existing game medium in a game and can specify (or easily specify) the type or state of the game medium placed on an object surface in the real world.

Detailed Description

Hereinafter, an example of an embodiment of the present invention will be described based on the drawings.

[1 ] embodiment 1 ] a system according to embodiment 1 of the present invention will be described.

Fig. 1 shows an example of the configuration of a system 1 according to embodiment 1. The system 1 is a system relating to a game played using a real object placed on an object surface set in the real world. As will be described later, the system 1 includes a function as a specifying system for specifying the type and state of an object placed on an object surface in the game. The system 1 also has a function as a display control system for displaying a display related to an object placed on an object surface in the game on a display unit.

For example, a card game played using a card corresponds to an example of [ a game played using an object placed on an object surface ]. Hereinafter, a system 1 according to embodiment 1 will be described by taking, as an example, a competitive card game (Trading card game) in which a player sets a deck (deck) by combining arbitrary cards from among cards owned by the player according to a predetermined rule and matches the deck with another player.

[ 1-1. overview of card game ] before explaining the configuration of the system 1, the overview of the card game will be explained.

Fig. 2A and 2B show an example of a card used in a card game. The card 60 is a rectangular object, for example, formed of paper or the like.

Fig. 2A shows an example of the appearance of the front surface 61 of the card 60. Fig. 2A shows a character card as an example of the card 60, which is a card showing a character.

As shown in fig. 2A, information about the card 60 is recorded on the front face 61 of the card 60. Since the character card is shown in fig. 2A, information related to the character is described on the front surface 61. For example, front face 61 includes portions P1, P2, P3, P4, P5. The portion P1 represents the name of the card 60 (character). Portion P2 is an image of a character. Part P3 represents an explanation about the role. Portion P4 represents the attack force (ATK) and defense force (DEF) of a character. Part P5 represents a card ID. The card ID is information for identifying each card type. For example, the appearance (pattern, text, etc.) of the front face 61 of the card 60 differs depending on the type of the card, and the card IDs of the cards 60 having the same appearance of the front face 61 are the same, and the card IDs of the cards 60 having different appearances of the front face 61 are different. For example, the card IDs of the cards 60 representing different characters are different. When there are only 1 kind of cards 60 indicating characters with the same name, the card IDs of the cards 60 indicating the same character are the same. On the other hand, when there are a plurality of types of cards 60 having different appearances of the front face 61 as the cards 60 indicating characters of the same name, the card IDs of the plurality of types of cards 60 are different. For example, when there are a plurality of types of cards 60 having different values, levels, and the like as the cards 60 representing characters having the same name, the card IDs of the plurality of types of cards 60 are different.

In fig. 2A, an example of a character card is shown as an example of a card 60 used in a card game, but a card 60 indicating a character other than a character is also used in a card game. For example, a magic card representing a magic or a capture card representing a capture (trap) is used. As with the character card, the information about the magic or capture is recorded on the front face 61 of the magic or capture card.

Fig. 2B shows an example of the appearance of the back surface 62 of the card 60. The back 62 of the card 60 has an appearance common to all cards used in card games. That is, the back surface 62 of the card 60 has a common appearance regardless of the type of the card 60. Therefore, the kind of the card 60 cannot be determined from the appearance of the back surface 62.

The card game is played by the 1 st player and the 2 nd player who play the battle placing the card 60 in the game field. Fig. 3 shows an example of a game field F. As shown in fig. 3, the playard F includes a 1 st playard F1, a 2 nd playard F2, and a community field F3.

Playground 1F 1 is an area for placing player 1's cards 60. The 1 st casino F1 includes a plurality of bays Z1-Z14.

For example, zone Z7 is an area for placing the 1 st player's deck as a card. Here, "card group" refers to a set of cards 60 in which the cards 60 owned by the player are arbitrarily combined by a predetermined rule when playing a card game, and "touch cards" refers to a card group which is shuffled and placed with the back surface facing upward. Player 1 can draw cards from the deck placed in zone Z7 and add to his hand.

The divisions Z2 to Z6 and Z8 to Z13 are areas for placing any card 60 selected by the 1 st player from his or her own hand.

For example, zones Z9-Z13 are areas for the 1 st player to place a character card from his hand. The 1 st player can use the character for combat (attack, etc.) by placing the character card in each of the divisions Z9 to Z13 from his or her own hand.

Further, for example, the divisions Z2 to Z6, Z8 are areas for the 1 st player to place magic cards or catch cards from his hand. The 1 st player can produce a magic or catching effect in the card game by placing magic cards or catching cards from his hand in the divisions Z2 to Z6 and Z8.

For example, zone Z14 is an area for placing a character card, a used magic card, or a capture card of a knocked down character. Zone Z1 is an area for placing a particular set of cards 60 that may be placed in zones Z29, Z30 of community F3. Player 1 may place cards 60 in zone Z29 or Z30 under prescribed conditions from a particular set of cards 60 placed in zone Z1.

Playground 2F 2 is an area for placing player 2's cards 60. Playard 2F 2 includes a plurality of bays Z15-Z28. The significance and action of the divisions Z15 to Z28 are the same as those of the divisions Z1 to Z14 of the 1 st casino F1, and therefore, the description thereof is omitted.

The community F3 is a community area for players 1 and 2. Pool F3 includes a plurality of bays Z29, Z30, where under prescribed conditions, both player 1 and player 2 can place cards 60 in bays Z29, Z30.

In the following, when it is not necessary to distinguish the individual divisions Z1 to Z30, they are collectively referred to as "division Z".

The card game is executed in a round system. That is, in the card game, the round of the 1 st player and the round of the 2 nd player are alternately repeated.

In player 1's round, player 1 extracts cards 60 from the collection of cards 60 (player 1's draw) placed in zone Z7, adding the extracted cards 60 to his hand. Under predetermined conditions, the 1 st player places an arbitrary card 60 from his hand in the divisions Z2 to Z6 and Z8 to Z13, or places an arbitrary card 60 from a special set of cards 60 placed in the division Z1 in the divisions Z29 and Z30, and performs an attack or the like on the 2 nd player using his card 60 placed in the playground F.

Similarly, in player 2's round, player 2 draws cards from the collection of cards 60 (player 2's draw) placed in zone Z21, adding the drawn cards 60 to his hand. Under predetermined conditions, the 2 nd player places an arbitrary card 60 from his hand in the divisions Z16 to Z20 and Z22 to Z27, or places an arbitrary card 60 from a special set of cards 60 placed in the division Z15 in the divisions Z29 and Z30, and uses his own card 60 placed in the playground F to perform an attack or the like on the 1 st player.

In a card game, a plurality of types of arrangement forms are defined as the arrangement form of cards, and the presence or absence of influence of the cards on the progress or result of the card game or the contents thereof are changed according to the arrangement form.

Fig. 4 is a diagram for explaining the arrangement form of the character card. As shown in fig. 4, 3 types of arrangement forms of the front attack display, the back defense display, and the front defense display are determined as arrangement forms of the character cards in the card game.

The "front side attack display" is a state in which the character card is placed right side up and vertically. "right side up" refers to a state in which the card 60 is placed so that the player can see the right side 61 of the card 60. In other words, [ right side up ] refers to a state in which the card 60 is placed so that the back surface 62 of the card 60 faces the game field F. The "longitudinal direction" refers to a state in which the card 60 is placed so that the card 60 looks long when viewed from the player. In other words, [ longitudinal direction ] means a state in which the card 60 is placed such that the longitudinal direction of the card 60 is parallel (or substantially parallel) to the longitudinal direction of the game field F. The player can perform a battle based on the attack force (ATK) of the character card by placing the character card in the front attack display.

The backside defensive display is a state in which the character card is placed horizontally with its back side facing upward. The term "back-side-up" refers to a state in which the card 60 is placed so that the player can see the back side 62 of the card 60 and cannot see the front side 61 of the card 60. In other words, [ back-side up ] refers to a state in which the card 60 is placed so that the front side 61 of the card 60 faces the game field F. The "lateral direction" refers to a state in which the card 60 is placed so that the card 60 looks horizontally long when viewed from the player. In other words, [ lateral direction ] refers to a state in which the card 60 is placed such that the longitudinal direction of the card 60 is parallel (or substantially parallel) to the lateral direction of the game field F. The player can perform a battle based on defensive power of character card (DEF) by placing the character card in a back-side defensive display.

The "front side defense display" is a state in which the character card is placed right side up and horizontally. The player can perform a battle based on defensive power (DEF) of the character card by placing the character card in a front defensive display.

When the character card is placed in the game field F, in principle, the player can select either one of the front-side attack display or the back-side defense display as the configuration form. A character card placed on the back side defense display becomes the positive side defense display (1) when an attack from an opponent is received. In the case where a player places a character card in a back-side defense display, an opponent can only attack the character card in a state where the opponent cannot know the name and performance (attack power, defense power, etc.) of the character card, and can know the name and performance of the character card at the time of attack. In some cases, the character card placed in the back-side defensive display is changed to the front-side defensive display when the effect of the specific magic card is activated. In addition, the player can change the own character card placed in the back-side defense display to the front-side attack display (2). Further, the player can change the arrangement form (3) of the own character card placed in the field F between the front-side attack display and the front-side defense display.

Similarly, in a card game, a plurality of arrangement forms are defined as arrangement forms of a magic card or a capture card. For example, there are 2 types of arrangement forms of a magic card or a capture card, namely, a front-side display and a back-side display. The front side display is a state in which the magic card or the capture card is placed vertically with the front side facing upward, and is a state in which the effect of the capturing shown by the magic card or the capture card is activated. On the other hand, [ back side display ] indicates a state in which the magic card or the capture card is placed with the back side facing upward and in the vertical direction, and indicates a state in which the effect of capturing indicated by the magic card or the capture card is waiting to be activated. The magic card or capture card placed in the back side display becomes the front side display at any time of the player or when a prescribed launch condition is satisfied, and the effect of the magic represented by the magic card or capture represented by the capture card is launched. If the player places the magic card or the capture card in the back side display, the opponent continues to play without knowing the name or effect of the magic card or the capture card, and at the point in time when the magic card or the capture card becomes the positive side display, the opponent will know the name or effect of the magic card or the capture card.

The player selects or changes the arrangement form of the cards in order to compete against the opponent in consideration of the characteristics of the arrangement form as described above.

In the card game, when the number of points (life points) of the 2 nd player decreased by the attack of the 1 st player on the 2 nd player becomes zero, the 1 st player wins and the 2 nd player loses. On the other hand, when the point (life point) of the 1 st player decreased by the attack of the 2 nd player on the 1 st player becomes zero, the 2 nd player wins and the 1 st player fails.

In the present embodiment, the card 60 is used in a state of being housed in the sleeve. Fig. 5 is a diagram for explaining the sleeve. As shown in fig. 5, the sleeve 70 is a housing for housing 1 card 60. The sleeve 70 is a rectangular and bag-like object having three sides bonded to each other and the remaining one side serving as an opening, and the card 60 is accommodated in the sleeve 70 through the opening. The sleeve 70 is made of synthetic resin such as polypropylene. For example, the sleeve 70 is provided separately from the card 60 (sold, etc.).

The sleeve 70 has a front portion 71 and a back portion 72. The front face portion 71 is a face portion (opposite face portion) that is opposite to the front face 61 of the card 60 when the card 60 is housed in the sleeve 70. The back surface portion 72 is a surface portion (opposite surface portion) located on the opposite side of the front surface portion 71, and is a surface portion facing the back surface 62 of the card 60 when the card 60 is housed in the sleeve 70. As shown in fig. 5, the card 60 is housed in the sleeve 70 such that the front surface 61 of the card 60 faces the front surface portion 71 of the sleeve 70 (in other words, such that the rear surface 62 of the card 60 faces the rear surface portion 72 of the sleeve 70).

The front face portion 71 of the sleeve 70 is transparent, and is configured such that the front face 61 of the card 60 accommodated in the sleeve 70 can be seen from the outside of the sleeve 70 through the front face portion 71. The entire front portion 71 need not be transparent, and a part (e.g., an end portion) of the front portion 71 may not be transparent as long as the front surface 61 of the card 60 accommodated in the sleeve 70 can be seen from the outside of the sleeve 70. On the other hand, the back portion 72 of the sleeve 70 is opaque and has a common appearance with the back portion 72 of the other sleeve 70. That is, all the sleeves 70 have a common appearance as the back surface portion 72. Therefore, the sleeves 70 cannot be distinguished from each other from the appearance of the back surface portion 72. For example, the back portion 72 has the same appearance as the back 62 of the card 60.

The sleeve 70 is provided with an IC tag 73(RFID tag). The IC tag 73 has a function of performing wireless communication by radio waves or the like. For example, the IC tag 73 is a passive type IC tag that includes an IC chip and an antenna, receives a signal transmitted wirelessly from an IC tag reader via the antenna, and wirelessly returns information stored in the IC chip to the IC tag reader in response to the reception of the signal. The IC tag 73 may have a function of writing and storing information received from an IC tag writer via an antenna in an IC chip. The IC tag 73 is not limited to a passive type IC tag, and may be an active type IC tag.

For example, the IC tag 73 is provided at a position other than the front face portion 71 of the sleeve 70 so as to avoid the IC tag 73 from obstructing the front face 61 of the card 60 from view. In the present embodiment, the IC tag 73 is provided on the inner surface of the back surface portion 72 of the sleeve 70. For example, the IC tag 73 is attached to the inner surface of the back surface portion 72 by a seal or the like. The antenna of the IC tag 73 may be printed on the inner surface of the back surface portion 72. In addition, a tag ID as information for uniquely identifying each IC tag 73 is stored in the IC chip of the IC tag 73.

Since the back surface portion 72 of the sleeve 70 is opaque, the IC tag 73 is not visible from the outside of the sleeve 70. Therefore, if there is a difference in the installation position of the IC tag 73 between the sleeves 70 or if there is an individual difference in the IC tag 73 itself, it is possible to ensure that the sleeves 70 cannot be distinguished from each other from the back surface portion 72 of the sleeve 70.

In addition, if there is no difference in the installation position of the IC tag 73 or the IC tag 73 itself, or if such a difference is negligible, there is no particular problem even if the IC tag 73 is visible from the outside of the sleeve 70, the back surface portion 72 of the sleeve 70 may be made transparent. When both the front surface portion 71 and the back surface portion 72 of the sleeve 70 are made transparent, the IC tag 73 may be provided on the inner surface of the front surface portion 71.

When the IC tag 73 is attached to a part of the back surface portion 72 of the sleeve 70, the thickness of the portion where the IC tag 73 is provided is larger than the other portions, and stability in the case where a plurality of sleeves 70 are stacked may be impaired. Therefore, in order to make the thickness of the sleeve 70 uniform (or substantially uniform), for example, the thickness of the portion of the back surface portion 72 other than the portion where the IC tag 73 is provided may be set to a thickness equal to the thickness of the IC tag 73, or the IC tag 73 (antenna) may be disposed on the entire inner surface (or a wide range) of the back surface portion 72.

In the present embodiment, the card 60 is used in a state of being accommodated in the sleeve 70. The sleeve 70 functions to protect the card 60 from damage and the like, and also functions to determine the kind, state of the card 60 placed in the playard F, as described later. Hereinafter, the card 60 in the state of being accommodated in the sleeve 70 is referred to as "card 60S" for convenience sake, in order to distinguish the card 60 from the card 60 alone. In other words, the card 60 and the sleeve 70 when the card 60 is housed in the sleeve 70 are regarded as one object, and are described as "card 60S".

[ 1-2 ] System configuration referring back to FIG. 1, the configuration of the system 1 according to embodiment 1 will be described. As shown in fig. 1, the system 1 includes a game board 10, a camera 30, an information processing device 40, and a display terminal device 50.

The game board 10 is a board on which cards are placed for the 1 st player and the 2 nd player who play the card game. For example, the game board 10 is disposed on the table 2 on which the 1 st player and the 2 nd player sit face to face.

The game board 10 includes a case 11 and a mat 12 placed on an upper surface of the case 11. A playard F (zones Z1 to Z30) is drawn on the mat 12. In addition, the case 11 and the mat 12 may be integrally formed. That is, the field F may be drawn on the upper surface of the housing 11. Hereinafter, the placement of the card 60S on the game board 10 (mat 12) is described as [ the placement of the card 60S in the game field F ].

Fig. 6 is a diagram for explaining the game board 10, and shows the game board 10 as viewed from above. As shown in FIG. 6, a plurality of reading devices 20-1 to 20-30 are provided inside a housing 11 of a game board 10. The reading devices 20-1 to 20-30 are IC tag readers, respectively. The IC tag reader includes an antenna for transmitting and receiving a signal to and from an IC tag, and reads information stored in the IC tag (IC chip) by transmitting the signal wirelessly and receiving a signal returned from the IC tag having received the signal.

The reading devices 20-1 to 20-30 are provided so as to correspond to the bays Z1 to Z30 of the playground F, respectively. For example, the reader 20-1 corresponds to the zone Z1 and is disposed at a position corresponding to the zone Z1. Specifically, reading device 20-1 is disposed below section Z1, and reads information stored in IC tag 73 of card 60S placed in section Z1. The same applies to the reading devices 20-2 to 20-30. Hereinafter, the respective reading devices 20-1 to 20-30 will be collectively referred to as "reading device 20" without distinguishing them.

The card 60 and the front face portion 71 and the back face portion 72 of the sleeve 70 are formed of a material that does not inhibit transmission and reception of signals between the IC tag 73 and the reader 20. Therefore, even if the card 60S is placed in the partition Z so as to face upward or face downward, the reader 20 disposed below the partition Z can read the information stored in the IC tag 73 of the card 60S.

Further, even in the case where a plurality of cards 60S are stacked in layers in 1 division Z, the reading device 20 provided below the division Z can read the information stored in the IC tags 73 of the respective plurality of cards 60S.

The reading device 20 provided below the zone Z is provided separately from the other zones Z, and does not read information stored in the IC tag 73 of the card 60S provided in the other zones Z.

The game board 10 and the information processing device 40 are connected by a cable conforming to a prescribed interface standard. Alternatively, the game board 10 and the information processing device 40 can communicate via a communication network. The reading result data relating to the reading result of the reading device 20 is supplied to the information processing device 40 through the above-described cable or communication network.

The imaging device 30 is a visible light camera, and is a device that converts an optical image obtained through a lens into an electronic image signal by an image sensor and outputs the electronic image signal. The imaging device 30 is fixed above the game board 10 (game field F) and images the game field F. The captured image of the imaging device 30 includes at least the divisions Z1 to Z30 of the game field F.

The imaging device 30 and the information processing device 40 are connected via a cable conforming to a prescribed interface standard. Alternatively, the imaging device 30 and the information processing device 40 can communicate via a communication network. The image pickup device 30 picks up an image of the game field F at predetermined intervals, and the picked-up image is supplied to the information processing device 40 via the cable or the communication network.

The information processing apparatus 40 is a computer, and includes a control unit 41, a storage unit 42, a communication unit 43, an operation unit 44, a display unit 45, and a sound output unit 46. The control unit 41 includes at least 1 microprocessor and executes information processing in accordance with a program stored in the storage unit 42. The storage unit 42 includes a main storage unit (e.g., RAM) and an auxiliary storage unit (e.g., nonvolatile semiconductor memory, hard disk drive, solid-state drive, or the like), and stores programs and data. The communication unit 43 is used for communicating with other devices via a communication network. The operation unit 44 is used for an operator to perform various operations. The display unit 45 is used for displaying an image, and is, for example, a liquid crystal display, an organic EL display, or the like. The sound output unit 46 is for outputting sound, and is, for example, a speaker, an earphone, or the like. The operation unit 44, the display unit 45, and the audio output unit 46 may be provided in the information processing device 40 itself, or may be provided as an external device connected to the information processing device 40. For example, the display unit 45 may be a Head Mounted Display (HMD), a monitor, a television receiver, a projector, or the like connected to the information processing apparatus 40 as an external apparatus.

The information processing device 40 determines the type and state of the card 60S placed on the field F (i.e., the type and state of the card 60 placed on the field F in the state of being housed in the sleeve 70) based on the read result data of the reading device 20 and the captured image of the imaging device 30. Further, based on the determination result, the information processing device 40 causes the display terminal device 50 to display a game field image indicating the current situation of the game field F. The processing performed by the information processing device 40 will be described later (see fig. 10, 12, 13, 18, and the like).

The display terminal device 50 is a device capable of displaying an image. For example, the display terminal device 50 is a device for viewers who view a match of a card game. Specifically, the display terminal device 50 is a terminal device (for example, a smartphone, a tablet computer, a laptop computer, a desktop computer, or the like) used by each viewer, and as shown in fig. 1, is a computer including a control unit 51, a storage unit 52, a communication unit 53, an operation unit 54, a display unit 55, and a sound output unit 56. The control unit 51, the storage unit 52, the communication unit 53, the operation unit 54, the display unit 55, and the audio output unit 56 are the same as the control unit 41, the storage unit 42, the communication unit 43, the operation unit 44, the display unit 45, and the audio output unit 46. Although the operation unit 54 and the display unit 55 are shown separately in fig. 1, the operation unit 54 and the display unit 55 may be integrally formed as a touch panel. The operation unit 54 may be a pointing device such as a mouse, a button (key), a lever (joystick), or the like. The operation unit 54 may be used for the viewer to perform operations by voice or gestures.

Hereinafter, a description will be given assuming that the display terminal device 50 is a terminal device (for example, a smartphone or the like) used by each viewer, but the display terminal device 50 is not limited to this. For example, the display terminal device 50 may be a display-only device having only a display function. For example, the display terminal device 50 may be a large monitor that is provided at a meeting place where a plurality of viewers are present and that can be viewed by the plurality of viewers.

A game field image showing the current status of the game field F (game board 10) is displayed on the display unit 55 of the display terminal device 50, for example. The spectator can grasp the current situation of the game field F by viewing the game field image.

Fig. 7 shows an example of the situation of the game field F (game board 10), and fig. 8 shows an example of the game field image in the case of the situation shown in fig. 7.

In the situation shown in FIG. 7, card 60S-1 is placed in zone Z10 in a back side defensive display. In addition, card 60S-2 is placed in zone Z12 in a manner that shows a positive side attack. Further, a card set 600-1 (a card of the 1 st player), 600-2, 600-3 (a card of the 2 nd player), 600-4 as a plurality of cards 60S stacked with the back faces thereof facing upward are placed in the divisional areas Z7, Z1, Z21, Z15, respectively. Further, card set 600-1 includes 50 cards 60S, and card set 600-2 includes 12 cards 60S. Further, assume that 45 cards 60S are included in card collection 600-3, and 15 cards 60S are included in card collection 600-4.

As shown in fig. 8, a game field image G indicates the current situation of the game field F. The game field image G includes zones Z1 to Z30. The game field image G shown in FIG. 8 includes portions PA-1, PA-2, PA-3, PA-4, PB-1, PB-2.

Portion PA-1 is an object corresponding to card set 600-1 placed in zone Z7, displayed in association with zone Z7. Portion PA-2 is an object corresponding to card set 600-2 placed in zone Z1, displayed in association with zone Z1. Portion PA-3 is an object corresponding to card set 600-3 placed in zone Z21, displayed in association with zone Z21. Portion PA-4 is an object corresponding to card set 600-4 placed in zone Z15, displayed in association with zone Z15. The numerical value described in the section PA-1 indicates the number of cards 60S included in the card set 600-1. The same applies to the portions PA-2 to PA-4.

Portion PB-1 is an object corresponding to card 60S-1 placed in zone Z10, and is displayed in association with zone Z10. In the situation shown in fig. 7, card 60S-1 is placed in zone Z10 with the backside defensive display, and therefore, as section PB-1, an image representing card 60 placed in a lateral and backside-up orientation (i.e., an image representing back side 62 of card 60 placed in a lateral orientation) is displayed at a position corresponding to zone Z10. In other words, as the portion PB-1, an image corresponding to the kind of the card 60 is not displayed, but an image unrelated to the kind of the card 60 is displayed at a position corresponding to the division Z10.

Portion PB-2 is an object corresponding to card 60S-2 placed in partition Z12, and is displayed in association with partition Z12. In the situation shown in fig. 7, card 60S-2 is placed in section Z12 in such a manner that the front attack display is made, and therefore, as section PB-2, an image representing card 60 placed in a longitudinal and face-up manner (i.e., an image representing front face 61 of card 60 placed in the longitudinal direction) is displayed at a position corresponding to section Z12. In other words, as the portion PB-2, an image corresponding to the type of the card 60 is displayed at a position corresponding to the division Z12, unlike the portion PB-1.

Processing for displaying information on card 60S-1 placed in partition Z10 is associated with portion PB-1. Therefore, when an operation for designating the part PB-1 (for example, a click operation on the part PB-1) is accepted, information on the card 60S-1 is displayed. FIG. 9 shows an example of a game field image G when a designation operation of a part PB-1 is accepted. When the operation for designating the portion PB-1 is accepted, the image showing the front face 61 of the card 60S-1 placed in the section Z10 is displayed as the portion PC as shown in FIG. 9.

Normally, the viewer cannot grasp the name and performance of the card 60S-1 placed with the back surface facing upward, but in the present embodiment, the part PC shown in fig. 9 is displayed in accordance with the designation operation of the part PB-1, so the viewer can grasp the name and performance of the card 60S-1 placed with the back surface facing upward. Instead of displaying the image representing the front face 61 of the card 60S-1 as the part PC, a text message representing the name, performance of the card 60S-1 may be displayed as the part PC.

As with portion PB-1, the processing for displaying information for card 60S-2 placed in partition Z12 is associated with portion PB-2. Therefore, when the designation operation of the portion PB-2 is accepted, the image showing the front face 61 of the card 60S-2 is displayed as the portion PC. Since portion PC is larger than portion PB-2, the viewer can easily grasp the name, performance, of card 60S-2 placed in partition Z12 by referring to portion PC.

Further, a process for displaying a list of cards 60S included in card set 600-1 placed in partition Z7 may be associated with portion PA-1. Further, a list of cards 60S included in the card set 600-1 may be displayed in accordance with the designation operation of the section PA-1. In this manner, the viewer may grasp the list of cards 60S contained in card set 600-1 placed in section Z7. The same applies to the portions PA-2 to PA-4.

In addition, although the above description has been made of the case where the game field image G displayed on the display unit 55 of the display terminal device 50 is changed (for example, from the state shown in fig. 8 to the state shown in fig. 9) in accordance with the operation performed by the viewer on the display terminal device 50, the game field image G displayed on the display unit 55 of the display terminal device 50 may be changed in accordance with the operation performed on the information processing device 40. For example, a part of the PC shown in fig. 9 may be displayed in the game field image G in response to a designation operation performed by a representative who plays a card game, commentary, or the like using the operation unit 44 of the information processing device 40.

In addition to the game field image G, the image captured by the imaging device 30 may be displayed on the display unit 55 of the display terminal device 50. For example, both the game field image G and the image captured by the imaging device 30 may be displayed on the display unit 55. For example, the image displayed on the display unit 55 may be switched between the game field image G and the captured image of the imaging device 30 in accordance with a predetermined switching instruction.

Processes the processes performed by the system 1 are explained.

[ 1-3-1 ] As will be described later, the information processing device 40 executes determination processing for determining the type and state of the card 60S placed in the game field F based on the reading result of the reading device 20. In order to perform this determination process, it is necessary to associate the card ID of the card 60 with the sleeve 70 that houses the card 60. Therefore, before starting the card game, a correlation process for correlating the card ID of the card 60 with the sleeve 70 that houses the card 60 is executed.

[ 1-3-1-1 ] FIG. 10 is a flowchart showing an example of the association processing. For example, the player places 1 card 60S of his own card set in a prescribed division Z (e.g., division Z11, etc.) in the field F in a vertical and face-up manner. In this state, the association processing shown in fig. 10 is executed.

As shown in fig. 10, first, the control unit 41 of the information processing device 40 acquires a captured image of the imaging device 30 (S400). Then, the control section 41 specifies the card ID of the card 60S captured in the captured image (that is, the card ID of the card 60 placed in the aforementioned zone Z in the state of being housed in the sleeve 70) from the captured image (S402).

For example, a learned model (a model for specifying the card ID of the card 60S captured in the captured image) generated by performing machine learning based on learning data including the captured image of the game field F on which the card 60S is placed and the card ID (positive solution data) of the card 60S is stored in advance in the storage unit 42. Then, in step S402, the control unit 41 specifies the card ID of the card 60S captured in the captured image using the learned model.

Further, the storage unit 42 may store feature data in advance, in which the card ID of the card 60S is associated with appearance feature information indicating appearance features of the card 60S. Then, in step S402, the control portion 41 may extract appearance feature information of the card 60S captured in the captured image by analyzing the captured image, and determine a card ID associated with the extracted appearance feature information (or appearance feature information most similar to the extracted appearance feature information) as the card ID of the card 60S captured in the captured image.

After executing step S402, the control unit 41 acquires the tag ID read by the reader 20 (S404). In a case where the card 60S is placed in the above-described zone Z, the tag ID stored in the IC tag 73 of the card 60S is read by the reading device 20 provided below the above-described zone Z, and the read tag ID is supplied to the information processing device 40. The control unit 41 acquires the tag ID thus supplied.

After executing step S404, the control section 41 registers the association between the card ID determined in step S402 and the tag ID acquired in step S404 in the association data D1 (S406).

Fig. 11 shows an example of the related data D1 stored in the storage unit 42. The association data D1 includes "card ID" and "tag ID" fields. The "card ID" field is a field for registering a card ID, and the "tag ID" field is a field for registering a tag ID.

In step S406, the control unit 41 adds a new record to the related data D1, and registers the card ID determined in step S402 and the tag ID acquired in step S404 in the [ card ID ] and [ tag ID ] fields of the added record.

After step S406 is performed, a completion notification indicating that the association processing is completed is output. For example, an image indicating the completion notification is displayed on the display unit 45, or a sound indicating the completion notification is output from the sound output unit 46. According to the completion notification, the player removes the card 60S placed in the zone Z, and places the next card 60S in the zone Z from the own card set in a vertically and right-side-up manner. In this state, the association processing shown in fig. 10 is executed again.

By executing the association processing shown in fig. 10, the information on all the cards 60S included in the card set of the 1 st player is registered in the association data D1 with respect to the cards 60S included in the card set of the 1 st player. Further, the association processing shown in fig. 10 is also executed for each card 60S included in the deck of the 2 nd player, whereby information on all cards 60S included in the deck of the 2 nd player is registered in the association data D1.

[ 1-3-1-2 ] the association processing is not limited to the processing shown in FIG. 10. Fig. 12 is a flowchart showing another example of the association processing. The association processing shown in fig. 12 may be performed instead of the association processing shown in fig. 10.

In addition, the association processing shown in fig. 12 is premised on an IC tag writer for writing information to the IC tag 73 being provided below the above-described partition Z. Hereinafter, a case will be described where the reading device 20 provided below the above-described partition Z is an IC tag reader/writer having both functions of an IC tag reader and an IC tag writer.

As shown in fig. 12, first, the control unit 41 of the information processing device 40 acquires a captured image of the imaging device 30 (S420). Then, the control section 41 specifies the card ID of the card 60S captured in the captured image from the captured image (S422). The processing of steps S420 and S422 is the same as steps S400 and S402 in fig. 10.

After executing step S422, the control unit 41 writes the card ID determined in step S422 into the IC tag 73 of the card 60S placed in the zone Z (S424). That is, the control unit 41 transmits the write instruction of the card ID determined in step S422 to the reading device 20 placed below the zone Z. Then, in accordance with the write instruction, the reader 20 writes the card ID determined in step S422 into the IC tag 73 of the card 60S placed in the above-described zone Z.

By executing the association processing shown in fig. 12 for each card 60S included in the deck group of the 1 st player, the card ID of the card 60S is stored in the IC tag 73 of each card 60S included in the deck group of the 1 st player. Also, by executing the association processing shown in fig. 12 with respect to each card 60S included in the deck group of the 2 nd player, the card ID of each card 60S included in the deck group of the 2 nd player is stored in the IC tag 73 of each card 60S. In this case, the association between the card ID of the card 60 and the sleeve 70 that houses the card 60 is not stored as the association data D1 as shown in fig. 11, but is stored in the IC tag 73 of each sleeve 70.

[ 1-3-1-3 ] here, the case where the association processing is performed using the system 1 is explained, but it is not necessary to perform the association processing using the system 1. For example, a system for association including an imaging device and an IC tag reader (IC tag reader/writer) may be separately prepared from the system 1, and the association process may be executed using the system. In addition, the association may be completed at the time of starting the card game, and the time of executing the association may not be immediately before starting the card game.

[ 1-3-2 ] during the play of a card game, the information processing device 40 executes a determination process for determining the type and state of a card 60S placed in the field F. Fig. 13 is a flowchart showing an example of the determination processing. The determination processing shown in fig. 13 is premised on the storage unit 42 storing the related data D1 shown in fig. 11.

As shown in fig. 13, first, the control unit 41 of the information processing device 40 acquires a captured image of the imaging device 30 (S430). Then, the control unit 41 specifies the position and orientation of the card 60S placed on the game field F based on the captured image (S432).

In the present embodiment, for example, as shown in fig. 14, 35 regions a1 to a35 are set, each of which is a captured image I divided into 5 × 7 vertical and horizontal regions. The areas a1 to a30 are set so as to correspond to the bays Z1 to Z30 of the playard F. In the following, when it is not necessary to specify the respective regions a1 to a35, they are collectively referred to as "region a".

In step S432, the control unit 41 determines whether or not the card 60S is captured in each area a of the captured image, and the orientation (vertical and horizontal orientation, front and back orientation) of the captured card 60S. Here, [ determining the orientation of the longitudinal and lateral sides of the card 60S ] means determining in which of the longitudinal and lateral directions the card 60S is placed, and [ determining the orientation of the front and back sides of the card 60S ] means determining in which of the front and back sides the card 60S is placed.

For example, a learned model (a model for determining whether or not the card 60S is photographed in each area a of the photographed image and the direction of the photographed card 60S) generated by performing machine learning based on learning data including the photographed image of the game field F where the card 60S is placed and forward solution data indicating the area a where the card 60S is placed and the direction of the card 60S is stored in advance in the storage unit 42. Then, in step S432, the control unit 41 determines whether or not the card 60S is captured in each area a of the captured image and the orientation of the captured card 60S, using the learned model.

Note that, in the storage unit 42, data in which the orientation of the card 60S is associated with appearance feature information indicating the feature of the appearance of the card 60S when the card 60S is placed in the orientation may be stored in advance for each card 60S. Then, in step S422, the control unit 41 may determine whether or not the card 60S is captured in the area a of the captured image by analyzing the captured image to determine whether or not the appearance feature information of the card 60S is extracted from the area a, or may determine the orientation of the card 60S captured in the area a based on the extracted appearance feature information.

The determination result in step S432 is registered in the 1 st determination result data D2. Fig. 15 shows an example of the 1 st determination result data D2. As shown in fig. 15, the 1 st determination result data D2 includes [ area ID ], [ vertical and horizontal marks ], and [ front and back marks ] fields.

The [ area ID ] field indicates an area ID as information for uniquely identifying each area a set in the captured image. The [ vertical and horizontal marks ] field is a field for registering vertical and horizontal marks indicating the result of determination of the vertical and horizontal orientations of the card 60S photographed in the area a. For example, in the case where it is determined that the card 60S is the portrait, the value [0] is registered in the [ vertical/horizontal mark ] field, and in the case where it is determined that the card 60S is the landscape, the value [1] is registered in the [ vertical/horizontal mark ] field. The [ front/back mark ] field is a field for registering a front/back mark indicating a result of determination of the front/back direction of the card 60S captured in the area a. For example, in the case where it is determined that the card 60S is right-side-up, the value [0] is registered in the [ right-side-up mark ] field, and in the case where it is determined that the card 60S is back-side-up, the value [1] is registered in the [ right-side-up mark ] field. When the card 60S is not captured in the area a, the fields of the [ vertical and horizontal marks ] and the [ front and rear marks ] are set to Null (Null). In addition, among the records of the 1 st determination result data D2, a record in which [ An ] (n: a natural number) is registered in the [ area ID ] field is described as a record of [ area ID [ An ].

For example, in the case of the situation shown in fig. 7, in step S432, (a) the card 60S is photographed in each of the areas a1, a7, a10, a12, a15, a21, (b) the card 60S photographed in the area a10 is oriented in the lateral direction with the back surface facing upward, (c) the card 60S photographed in the area a12 is oriented in the longitudinal direction with the front surface facing upward, and (D) the card 60S photographed in the areas a1, a7, a15, a21 is determined to be oriented in the longitudinal direction with the back surface facing upward from the photographed image, and the determination result is registered in the 1 st determination result data D2.

After executing step S432, the control unit 41 acquires the read result data of each reading device 20 supplied from the game board 10 (S434), and specifies the position and the card ID of the card 60S placed in the game field F based on the read result data (S436).

In the case of the situation shown in fig. 7, for example, the reading device 20-10 provided below the partition Z10 reads the tag ID stored in the IC tag 73 of the card 60S-1 placed in the partition Z10, and supplies the tag ID to the information processing device 40 as the reading result data. Then, the control section 41 refers to the related data D1, and determines the card ID associated with the tag ID read by the reading device 20-10. Thus, the card ID of the card 60S-1 placed in the partition Z10 is determined.

Likewise, the reading device 20-12 disposed below the partition Z12 reads the tag ID stored in the IC tag 73 of the card 60S-2 placed in the partition Z12 and supplies the tag ID as the read result data to the information processing device 40. Then, the control section 41 refers to the related data D1, and determines the card ID associated with the tag ID read by the reading device 20-12. Thus, the card ID of the card 60S-2 placed in the partition Z12 is determined.

Further, reading device 20-7 provided below division Z7 reads the tag IDs stored in IC tags 73 of respective cards 60S included in card set 600-1 placed in division Z7, and supplies these tag IDs as read result data to information processing device 40. Then, the control section 41 refers to the related data D1 and specifies the card ID associated with each tag ID read by the reading device 20-7. Thus, the card ID of each card 60S included in card set 600-1 placed in partition Z7 is determined. The card IDs of the zones Z1, Z15, and Z21 are also specified in the same manner as the zone Z7.

The determination result in step S436 is registered in the 2 nd determination result data D3. Fig. 16 shows an example of the 2 nd determination result data D3. As shown in fig. 16, the 2 nd determination result data D3 includes [ reading device ID ] and [ card ID ] fields.

The [ reading device ID ] field indicates a reading device ID as information that uniquely identifies each reading device 20. In FIG. 16, the reading device ID of the reading device 20-n (n: natural number) is represented as [ Rn ]. The [ card ID ] field is a field for registering a card ID determined from the reading result data of the reading device 20. With respect to the reading device 20 that does not read the tag ID stored in the IC tag 73, the [ card ID ] field is set to Null (Null). In addition, among the records of the 2 nd determination result data D3, a record in which [ Rn ] (n: a natural number) is registered in the [ reading apparatus ID ] field is described as a record of [ reading apparatus ID [ Rn ].

For example, in the case of the situation shown in fig. 7, the card ID determined from the tag ID read by the reading device 20-10 (i.e., the card ID of the card 60S-1 placed in the zone Z10) is registered with the [ card ID ] field of the record of the reading device ID [ R10 ]. In addition, the card ID determined from the tag ID read by the reading device 20-12 (i.e., the card ID of the card 60S-2 placed in the partition Z12) is registered for the [ card ID ] field of the record of the reading device ID [ R12 ].

Further, a list of card IDs specified from the plurality of tag IDs read by the reader 20-7 (i.e., a list of card IDs of cards 60S included in the card set 600-1 placed in the partition Z7) is registered in the [ card ID ] field of the record of the reader ID [ R7 ]. The same applies to the [ card ID ] field of the records of the reading device IDs [ R1], [ R15], and [ R21 ]. The [ card ID ] field of a record other than the records of the reader ID [ R1], [ R7], [ R10], [ R12], [ R15], and [ R21] is set to Null (Null).

Here, although the description has been given on the assumption that the related data D1 shown in fig. 11 is registered in the storage unit 42 by the related processing shown in fig. 10, when the card ID of the card 60S is registered in the IC tag 73 of the card 60S by the related processing shown in fig. 12, the processing described below is executed in step S436.

In the case of the situation shown in fig. 7, for example, the reading device 20-10 provided below the partition Z10 reads the card ID stored in the IC tag 73 of the card 60S placed in the partition Z10, and supplies the card ID to the information processing device 40 as the reading result data. Then, the control section 41 registers the card ID read by the reading device 20-10 in the [ card ID ] field of the record of the reading device ID [ R10 ]. The same applies to the partition Z12.

Further, reading device 20-7 provided below division Z7 reads the card IDs stored in IC tags 73 of respective cards 60S included in card set 600-1 set in division Z7, and supplies these card IDs as reading result data to information processing device 40. Then, the control section 41 registers the plurality of card IDs read by the reading device 20-7 in the [ card ID ] field of the record of the reading device ID [ R7 ]. The same applies to the partitions Z1, Z15 and Z21.

After executing step S436, the control section 41 generates the field situation data D4 from the 1 st determination result data D2 and the 2 nd determination result data D3 (S438).

Fig. 17 shows an example of the field situation data D4. The field situation data D4 is data indicating the current situation of the field F. More specifically, the yard situation data D4 is data indicating the current situation of each section Z in the yard F (whether or not the card 60S is placed in the section Z, the type and arrangement of the card 60S placed in the section Z).

As shown in fig. 17, the field situation data D4 includes [ partition ID ], [ card ID ], [ vertical and horizontal marks ], and [ front and rear marks ] fields. The [ partition ID ] field indicates a partition ID as information for uniquely identifying each partition Z within the field F. The [ card ID ] field is the same as the [ card ID ] field of the 2 nd determination result data D3. The [ vertical and horizontal flag ] and [ front and rear flag ] fields are the same as the [ vertical and horizontal flag ] and [ front and rear flag ] fields of the 1 st determination result data D2. In the following description, of the records of the field situation data D4, the record in which [ Zn ] (n: a natural number) is registered in the [ partition ID ] field is described as the record of [ partition ID [ Zn ].

In step S438, the control unit 41 collates the [ area ID ] field of the 1 st determination result data D2 and the [ reader ID ] field of the 2 nd determination result data D3, and synthesizes the 1 st determination result data D2 and the 2 nd determination result data D3 to generate the field situation data D4.

For example, the record of the reading device ID [ R1] in the record of the 2 nd determination result data D3 and the record of the area ID [ a1] in the record of the 1 st determination result data D2 are both records regarding the reading device 20-1 or the area a1 corresponding to the partition Z1, and these records correspond to each other. Therefore, the control unit 41 registers, as information indicating the current status of the partition Z1, the card ID registered in the [ card ID ] field of the record of the reading device ID [ R1] in the record of the 2 nd determination result data D3, and the combination of the vertical and horizontal marks and the front and back marks registered in the [ vertical and horizontal marks ] and [ front and back marks ] fields of the record of the area ID [ a1], which is the record corresponding to the reading device ID [ R1] in the record of the 1 st determination result data D2, in the playground status data D4. That is, the control unit 41 registers the combination in the [ card ID ], [ vertical and horizontal marks ], and [ front and rear marks ] fields of the record of the partition ID [ Z1] in the record of the field situation data D4. The same applies to the divisions Z2 to Z30.

[ 1-3-3 ] during the playing of a card game, a display control process for displaying a game field image G on the display section 55 of the display terminal device 50 is executed. For example, the storage unit 42 stores card data in which the card ID is associated with the information and image (front face 61) of the card 60, and the game field image G is displayed based on the card data and the game field situation data D4. Fig. 18 shows an example of the display control process.

As shown in fig. 18, the control unit 41 of the information processing device 40 transmits data relating to the game field image G to the display terminal device 50 via the communication unit 43 (S440), and the display terminal device 50 receives the data via the communication unit 53 (S500). Then, based on the data, the control unit 51 of the display terminal device 50 causes the display unit 55 to display the game field image G (S502).

Here, [ data relating to the game field image G ] means data necessary for displaying the game field image G on the display terminal device 50 (display unit 55). For example, the card data or the field situation data D4 corresponds to an example of [ data relating to the field image G ]. The card data may be stored in the storage unit 52 of the display terminal device 50 in advance, and in this case, it is not necessary to transmit the card data to the display terminal device 50. Further, the game field image G itself may be transmitted to the display terminal device 50 as [ data relating to the game field image G ].

When the field image G is generated, it is determined whether the front-back mark of the card 60S registered in the field situation data D4 is [1] (in other words, whether the orientation of the card 60S specified in step S432 is the back-side-up). Then, according to the determination result, a portion indicating the card 60S is displayed in the game field image G.

For example, in the case where the front-back mark of the card 60S is not [1] (in other words, in the case where the orientation of the card 60S determined in step S432 is not back-side up but front-side up), an image showing the front side 61 of the card 60S, such as the portion PB-2 shown in fig. 7, is displayed in the game field image G as a portion showing the card 60S. That is, as a part showing the card 60S, an image corresponding to the card ID of the card 60S registered in the casino situation data D4 (in other words, an image corresponding to the type of the card 60S specified in step S432) is displayed.

On the other hand, when the front and back faces of the card 60S are marked as [1] (that is, when the orientation of the card 60S determined in step S432 is such that the back face is directed upward), an image showing the back face 62 of the card 60S, such as the portion PB-1 shown in fig. 7, is displayed as a portion showing the card 60S in the game field image G. That is, as a part indicating the card 60S, an image unrelated to the card ID of the card 60S registered in the casino situation data D4 (in other words, an image unrelated to the type of the card 60S specified in step S432) is displayed.

Further, the game field image G may be displayed on the display unit 45 of the information processing device 40. That is, the control unit 41 of the information processing device 40 may display the field image G on the display unit 45 based on the field situation data D4.

Fig. 19 shows an example of processing repeatedly executed by the display terminal device 50 while the game field image G is displayed.

As shown in fig. 19, the control unit 51 of the display terminal device 50 determines whether or not the card specification operation is accepted (S510). The card specifying operation is an operation of specifying the card 60S displayed in the game field image G. For example, in the case of the game field image G shown in FIG. 8, the designation operation of the portion PB-1 or PB-2 (e.g., a click operation on the portion PB-1 or PB-2, etc.) corresponds to the [ card designation operation ].

If it is determined that the card specification operation has been accepted (yes in S510), the control unit 51 displays the card image of the specified card 60S (S512). For example, a part PC shown in fig. 9 corresponds to [ card image ]. For example, when the designation operation of the portion PB-1 corresponding to the card 60S-1 placed in the division Z10 is performed in the state where the game field image G shown in FIG. 8 is displayed on the display unit 55, the control unit 51 displays the portion PC indicating the front surface 61 of the card 60S-1 placed in the division Z10.

Although omitted in fig. 19, when a prescribed deletion instruction operation (for example, a designation operation of designating a part PC) is performed in a state where the part PC is displayed, the control section 51 deletes the part PC.

When the display terminal device 50 receives the card specification operation, a notification indicating that the card specification operation has been received may be transmitted from the display terminal device 50 to the information processing device 40, and the control unit 41 of the information processing device 40 may return the game field image G as shown in fig. 9 to the display terminal device 50 to display the game field image G on the display terminal device 50.

When the game field image G is displayed on the display unit 45 of the information processing device 40, the control unit 41 of the information processing device 40 executes the processing shown in fig. 19.

Effects of 1-4 according to embodiment 1 described above, the type and state (position, orientation, etc.) of the card 60S placed on the game field F can be specified using not only the captured image of the imaging device 30 that images the game field F but also the read result of the reading device 20 that reads the information stored in the IC tag 73 of the card 60S. According to embodiment 1, it is possible to specify, based on the reading result of the reading device 20, an event that cannot be specified (or is difficult to specify) from the captured image of the imaging device 30.

For example, even in a case where the card 60S is placed in the game field F with the back surface facing upward (that is, in a case where the card 60S is placed in a state where the front surface 61 is not captured in the captured image of the imaging device 30), it is possible to specify the type of the card 60S or specify information (name, performance, and the like) described in the front surface 61 of the card 60S based on the reading result of the reading device 20. For example, even when the card 60S is subjected to hologram processing or the like, the type of the card 60S can be specified based on the reading result of the reading device 20, or information (name, performance, or the like) described on the front surface 61 of the card 60S can be specified. In addition, for example, even in a case where a plurality of cards 60S are stacked, the types of the plurality of cards 60S can be determined based on the reading result of the reading device 20.

In addition, in embodiment 1, since the determination result regarding the position and orientation of the card 60S is included in the determination result (1 st determination result) based on the captured image of the imaging device 30 and the determination result regarding the position and type of the card 60S is included in the determination result (2 nd determination result) based on the reading result of the reading device 20, the determination result (position determination result) regarding the position of the card 60S is included in both the 1 st determination result and the 2 nd determination result. Therefore, even when a plurality of cards 60S are placed in the game field F, the combination of the 1 st and 2 nd determination results with respect to the same card 60S can be determined by collating the position determination results included in both the 1 st and 2 nd determination results. That is, even when a plurality of cards 60S are placed in the game field F, a combination of the type, position, and orientation can be determined for each card 60S.

In embodiment 1, since the IC tag 73 is provided on the sleeve 70, even when the card 60 itself does not have an IC tag, the type and state of the card 60 can be determined from the reading result of the reader 20 by housing and using the card 60 in the sleeve 70.

That is, since the card 60 itself does not need to be provided with an IC tag, for example, an existing card 60 not provided with an IC tag can be used.

In addition, in the case where the card 60 itself includes an IC tag, if the IC tag of the card 60 is broken, the card 60 cannot be used, and the player may feel dissatisfied. There are also cards with high rarity among the cards 60, and when such cards 60 with high rarity are not usable due to a failure of the IC tag, the player may feel great dissatisfaction. In this regard, when the sleeve 70 includes the IC tag 73, even if the IC tag 73 fails, the card 60 can be continuously used by replacing the sleeve 70.

In addition, in embodiment 1, since the IC tag 73 is provided on the back surface portion 72 of the sleeve 70, it is possible to prevent the front surface 61 of the card 60 housed in the sleeve 70 from being hidden by the IC tag 73 and becoming difficult to see.

In embodiment 1, the appearance of the back surface portion 72 of the sleeve 70 is the same as that of all the sleeves 70, and therefore it is ensured that the sleeves 70 cannot be distinguished from each other from the appearance of the back surface portion 72.

In embodiment 1, since the game field image G is displayed on the display terminal device 50, the viewer (the person who views the display terminal device 50) can easily grasp the current situation of the game field F.

Further, in embodiment 1, even in a case where the card 60S is placed in the game field F with the back surface facing upward (that is, in a case where the card 60S is placed in a state where the front surface 61 is not visible), since the portion PC indicating the front surface 61 of the card 60S is displayed in the game field image G, it is possible for the viewer to provide new interest in being able to know information (name, performance, etc.) described in the front surface 61 of the card 60S placed in the back surface facing upward, which is originally unknown. As a result, the interest of the viewer in viewing the card game can be increased.

In addition, in embodiment 1, when a designation operation for designating the card 60S placed with the back surface facing upward (for example, a designation operation for designating the portion PB-1 of fig. 8) is accepted, the portion PC showing the front surface 61 of the card 60S is displayed, and therefore, for example, information (name, performance, and the like) of the card 60S placed with the back surface facing upward cannot be known in principle, and only when the viewer desires, it can be known by performing the above-described designation operation.

Modifications 1 to 5 modifications of embodiment 1 will be described.

[ 1-5-1 ] in the above-described embodiment, the sleeve 70 is provided with the IC tag 73, but the sleeve 70 may be configured not to be provided with the IC tag 73, and an object provided with the IC tag 73 and the card 60 may be housed in the sleeve 70.

For example, as shown in fig. 20, the object 80 housed in the sleeve 70 together with the card 60 may be provided with an IC tag 73. The object 80 is formed of a material that does not inhibit transmission and reception of signals between the IC tag 73 and the reader 20. For example, the object 80 is a sheet-like object having a similar shape to the card 60. In the example shown in fig. 20, the shape and size of the object 80 are the same as (or substantially the same as) the card 60, but the shape and size of the object 80 may be different from the card 60. In addition, the IC tag 73 may be mounted on any surface of the object 80.

The card 60 is accommodated in the sleeve 70 such that the front surface 61 faces the front surface 71 of the sleeve 70, and the object 80 is accommodated between the rear surface 62 of the card 60 and the rear surface 72 of the sleeve 70. When used in a card game, the card 60 and the object 80 are both used in a state of being housed in the sleeve 70. In addition, when the card 60 is used in a card game, both the card 60 and the object 80 may be stored in the sleeve 70, and when the card 60 is stored in the sleeve 70, it is not necessary to store the card 60 and the object 80 in the sleeve 70 at the same time. The object 80 may be housed in the sleeve 70 after the card 60 is housed in the sleeve 70, or the card 60 may be housed in the sleeve 70 after the object 80 is housed in the sleeve 70. The card 60 and the object 80 may also be received together in the sleeve 70 at the same time.

Even if the object 80 as described above is housed in the sleeve 70 together with the card 60, it is possible to specify, from the reading result of the reading device 20, the items that cannot be specified (or are difficult to specify) from the captured image of the imaging device 30, as in the case where the IC tag 73 is attached to the sleeve 70. Even when the card 60 itself does not include an IC tag, the type and state of the card 60 can be determined from the reading result of the reading device 20 by housing the card 60 in the sleeve 70 together with the object 80.

The [ 1-5-2 ] card 60 itself (e.g., the back surface 62) may be provided with an IC tag 73. In this way, it is also possible to specify, based on the reading result of the reading device 20, an event that cannot be specified (or is difficult to specify) from the captured image of the imaging device 30.

[ 1-5-3 ] the determination process shown in FIG. 13 may also be executed at a point in time when the player's card set is placed as a card in the partition Z7 or Z21 before starting the card game, and it is determined whether the player's card set placed in the partition Z7 or Z21 follows the rule based on the playground condition data D4. Further, a warning notification may also be output in the event that the card set does not comply with the rules.

The above description of [ 1-5-4 ] has been made on the case where the information stored in the IC tag 73 of the card 60S placed in the zone Z is not read by the reader 20 provided below the other zone Z, but when the information stored in the IC tag 73 of the card 60S is read by a plurality of readers 20, the reader 20 having the strongest signal intensity received from the IC tag 73 among the plurality of readers 20 can be regarded as the reader 20 that has read the information stored in the IC tag 73. For example, in the case where the information stored in the IC tag 73 of the card 60S is read by the reading devices 20-9, 20-10, if the received signal strength of the reading device 20-10 is stronger than that of the reading device 20-9, it can be determined that the card 60S is placed in the partition Z10.

[ 1-5-5 ] in the above-described embodiment, the readers 20-1 to 20-30 are provided at a plurality of positions corresponding to the partitions Z1 to Z30, respectively, but instead of this, the reader 20 having antennas arranged in a grid may be provided inside the casing 11 of the game board 10.

For example, as shown in fig. 21, as the antenna of the reader 20, a plurality of 1 st antennas 21 extending in the 1 st direction (for example, the longitudinal direction) may be arranged at predetermined intervals, and a plurality of 2 nd antennas 22 extending in the 2 nd direction (for example, the lateral direction) may be arranged at predetermined intervals. In this case, by identifying the combination of the 1 st antenna 21 and the 2 nd antenna 22 that received the signal from the IC tag 73 (in other words, the combination of the 1 st antenna 21 and the 2 nd antenna 22 that received the signal from the IC tag 73 with the strongest intensity), the position where the card 60S is placed can be identified. For example, the intersection of the 1 st antenna 21 and the 2 nd antenna 22 that receive the signal from the IC tag 73 (in other words, the 1 st antenna 21 and the 2 nd antenna 22 that have the strongest received signal strength) can be determined as the position where the card 60S is placed.

1-5-6 above, it is explained that the sleeve 70 is provided separately from the card 60 (sold, etc.), but the sleeve 70 may also be provided together with the card 60. In this case, the sleeve 70 may be provided in a state where the card ID is stored in the IC tag 73(IC chip).

[ 1-5-7 ] the card game played by the player is not limited to the above-described card game. For example, the positions and the number of the divisions Z set in the game field F are not limited to the example shown in fig. 3. Further, according to the card game, the area for placing the card 60 is not limited as in the divisions Z1 to Z30, and the player may place the card 60 at an arbitrary position in the game field F. Further, according to the modification shown in fig. 21, even in a case where the player places the card 60 at an arbitrary position within the game field F, the position where the card 60 is placed can be specified.

[ 1-5-8 ] the game played by the player may also be a game played using a game medium other than the card 60. For example, the game played by the player may be a game played using a game medium such as a doll, a pawn, or a card, or a game medium having a shape such as a pawn.

Functional elements [ 1-6 ] functional elements included in the system 1 will be described. Fig. 22 is a functional block diagram for explaining functional elements included in the system 1.

[ 1-6-1 ] the system 1 is a system relating to a game played using an object 100 placed on an object surface, and includes functional elements relating to the game.

The game played using the object 100 placed on the object surface is, for example, a game played by placing the object 100 on the object surface, and specifically, a game in which the type or state (position, orientation, or the like) of the object 100 placed on the object surface affects the progress or result (win or loss, success or loss, score, or the like) of the game. For example, a game in which 2 players place a game medium on a game field and play against each other corresponds to an example of the [ game ]. For example, a card game in which 2 players place the cards 60 on the game field F to play against each other as described above corresponds to an example of [ a game played using the object 100 placed on the object surface ].

The [ game ] is not limited to a game in which 2 players play against each other, and may be a game in which 3 or more players play against each other, or a game in which 1 player plays. The [ game ] may be a game in which 2 or more players cooperate to achieve the object.

The "object plane" is a plane provided in the real world, and is a plane on which the object 100 is placed. For example, the [ object plane ] is referred to as a [ playground ] or the like. The object surface may be a flat surface as long as the object 100 can be placed thereon, may have a surface with irregularities, or may be a curved surface.

The object 100 is an actually existing object to be placed on the object surface, and is an object to be used in the game. For example, the object 100 is an object in which a game medium is stored in a storage body. That is, the object 100 is a game medium stored in the storage body. In other words, the object 100 is a container in which the game medium is contained. For example, the object 100 may be a game medium itself (a game medium alone).

The game medium is, for example, a card, a doll, a chess piece, a card, or the like. The game medium may be an object having a shape like a chess piece.

The [ storage body ] is an object capable of storing each game medium. In other words, the [ housing ] refers to an inserted body into which the game medium can be inserted. [ Container ] is used for protecting a game medium. The housing is configured to be at least partially transparent, and at least an appearance characteristic portion (a portion having an appearance characteristic distinguishable from other game media) of the housed game media can be visually recognized from the outside of the housing. For example, the [ housing ] is a bag-like object and is called a [ sleeve ] or the like.

For example, the object 100 includes a recording surface, which is a surface on which information is recorded. The "description plane" is a plane on which information relating to the object 100 is described. For example, information corresponding to the type of the object 100 is described on the recording surface. In other words, information specific to the type of the object 100 is described on the description surface. For example, a text, a pattern, or the like unique to the type of the object 100 is described on the description surface. The information described on the recording surface may be referred to as information that can be specified according to the type of the object 100.

For example, when the object 100 is an object (or a single game medium) in which a game medium is stored in a storage body, information relating to the game medium stored in the storage body is recorded on a recording surface. For example, when the object 100 is an object (or a single card) in which a card is accommodated in a sleeve, the name and attribute of the card, the content of influence on the progress or result of a game, a pattern, or the like is described on the description surface.

Note that the term "description plane" refers to a plane in which, if the plane is captured in a captured image, the type of the object 100 can be specified from the captured image. That is, [ storage surface ] is a surface on which contents that can specify the type of the object 100 are stored.

The information described in [ description plane ] is not limited to information relating to the object 100, and may be information relating to a game.

In addition, for example, the object 100 includes a 1 st face and a 2 nd face different from the 1 st face. For example, the 2 nd face is a face located on the opposite side of the 1 st face. An angle between a normal direction of an outer side surface of the 1 st surface part and a normal direction of an outer side surface of the 2 nd surface part is 180 degrees or substantially 180 degrees. The 1 st face and the 2 nd face have the following relationship: that is, when the object 100 is placed on the target surface such that the outer side surface of the 1 st surface portion is in contact with the target surface, the outer side surface of the 2 nd surface portion faces upward, and when the object 100 is placed on the target surface such that the outer side surface of the 2 nd surface portion is in contact with the target surface, the outer side surface of the 1 st surface portion faces upward.

When the object 100 is an object in which a game medium is stored in a storage body, the storage body includes a 1 st surface portion and a 2 nd surface portion, and the game medium includes a recording surface. The inner side surface of the 1 st surface part is opposite to the inner side surface of the 2 nd surface part in a state that the game medium is not stored in the storage body, and the 1 st surface part (the inner side surface of the 1 st surface part) is opposite to the recording surface of the game medium in a state that the game medium is stored in the storage body. For example, the 1 st surface portion is formed entirely or partially of a transparent material (such as a transparent film), and the 1 st surface portion is configured to be able to visually recognize the surface of the game medium stored in the storage body from the outside of the storage body through the 1 st surface portion. When the game medium is a card, in a state where the card is stored in the storage body, the inner side surface of the 1 st face portion faces the 1 st face (for example, the front side ¬ setting face) of the card, and the inner side surface of the 2 nd face portion faces the 2 nd face (for example, the back side) of the card.

As shown in fig. 22, the object 100 includes a holding portion 101. The holding unit 101 holds specifying information described below. For example, the holding portion 101 is provided on a surface different from the recording surface. That is, the object 100 includes the above-described recording surface and a holding surface that is a surface provided with the holding portion 101.

For example, the specifying information is information for specifying the type or state of the object 100 placed on the object surface. That is, the specifying information is information as a basis for specifying at least one of the type and the state of the object 100 placed on the object surface. In other words, the specifying information includes at least one of information as a basis for specifying the type of the object 100 and information as a basis for specifying the state of the object 100. Note that [ information serving as a basis for specifying the type of the object 100 ] may be information indicating the type of the object 100 itself (in other words, information for identifying the type of the object 100). Note that [ information serving as a basis for specifying the state of the object 100 ] may be information indicating the state of the object 100 itself.

When the object 100 is an object (or a single game medium) in which a game medium is stored in the storage body, the identification information is information for identifying the type or state of the game medium placed on the object surface (or the single game medium placed on the object surface) in the state of being stored in the storage body. That is, the identification information includes at least one of information as a basis for identifying the type of the game medium (or the single game medium) stored in the storage body and information as a basis for identifying the state of the game medium (or the single game medium) stored in the storage body.

When there is data in which a container ID that is identification information for uniquely identifying a container and a game medium ID that is identification information for uniquely identifying the type of a game medium stored in the container are associated with each other, and the type of a game medium stored in the container can be specified based on the container ID, the container ID corresponds to an example of [ information that is a basis for specifying the type of a game medium stored in the container ]. In addition, identification information that uniquely identifies the holding portion 101 can be used as the container ID. For example, when the holding portion 101 is an IC tag, a tag ID that is identification information for uniquely identifying each IC tag can be used as the container ID.

Further, the information indicating the type of the game medium itself stored in the storage body (in other words, the information identifying the type of the game medium) may correspond to an example of [ information as a basis for specifying the type of the game medium stored in the storage body ]. Specifically, the game medium ID as identification information for uniquely identifying the type of the game medium may correspond to an example of [ information as a basis for specifying the type of the game medium stored in the storage body ].

The identification information is information for identifying information described on a recording surface of the object 100 placed on the target surface, for example. That is, the identification information is information that is a basis for identifying information described on the recording surface of the object 100 placed on the object surface. For example, the information described on the description surface is information related to the type of the object 100, and if the type of the object 100 is specified, if the information described on the description surface can be specified, the information serving as a basis for specifying the type of the object corresponds to [ information serving as a basis for specifying the information described on the description surface of the object 100 ].

In the above-described card game, the game field F (in other words, the mat 12) corresponds to an example of [ object surface ]. The card 60 corresponds to an example of the [ game medium ], and the sleeve 70 corresponds to an example of the [ storage body ]. The card 60S as an object in which the card 60 is housed in the sleeve provided with the IC tag 73 corresponds to an example of the object 100. The front portion 71 and the rear portion 72 of the sleeve 70 correspond to examples of [ 1 st portion ] and [ 2 nd portion ], respectively. The front surface 61 of the card 60S corresponds to an example of the "recording surface", and the inner surface of the rear surface portion 72 of the sleeve 70 corresponds to an example of the "holding surface".

The IC tag 73 of the card 60S corresponds to an example of the holding portion 101. The tag ID corresponds to an example of [ specifying information held in the holding unit 101 ] (information as a basis for specifying the type of game medium stored in the storage body). In addition, when the association processing shown in fig. 12 is executed, the card ID written in the IC tag 73 corresponds to an example of [ specifying information held in the holding portion 101 ] (information as a basis for specifying the type of game medium stored in the storage body).

In the modification shown in fig. 20, the card 60S as an object in which the object 80 provided with the IC tag 73 and the card 60 are housed in the sleeve 70 corresponds to an example of the object 100, and the IC tag 73 provided in the object 80 corresponds to an example of the holding portion 101. In the case of the modified example in which the card 60 itself includes the IC tag 73, the card 60 alone corresponds to an example of the object 100, and the IC tag 73 included in the card 60 corresponds to an example of the holding portion 101.

The system 1 includes an imaging unit 110, a captured image acquisition unit 120, a reading unit 130, a reading result acquisition unit 140, a specification unit 150, and a display control unit 160, and is a functional element for specifying the type and state of an object 100 placed on a target surface and a functional element for displaying a display related to the object 100 placed on the target surface on a display unit 170.

[ 1-6-3 ] an imaging unit 110 images a target surface on which the target 100 is placed. For example, the imaging unit 110 images the target surface from above. The imaging unit 110 may be an imaging unit that can image the entire target surface, or may be an imaging unit that can image only a region of the target surface where the target object 100 is likely to be placed. In the present embodiment, the imaging device 30 corresponds to the imaging unit 110.

[ 1-6-4 ] A reading unit 130 reads information held by a holding unit 101 of an object 100 placed on an object surface.

The object 100 includes a recording surface on which information is recorded and a holding surface that is a surface provided with the holding portion 101, and the reading portion 130 can read information held by the holding portion 101 of the holding surface of the object placed on the object surface so that the recording surface faces the object surface.

For example, the holding unit 101 is an IC tag, and the reading unit 130 reads information stored in the IC tag. That is, the reading section 130 includes 1 or more IC tag readers. For example, the reading section 130 includes a plurality of IC tag readers provided at a plurality of positions corresponding to a plurality of positions of the target surface, respectively. The reading unit 130 includes, for example, an IC tag reader having antennas disposed so as to pass through a plurality of positions on the target surface. In other words, the reading unit 130 includes a plurality of antennas that receive signals transmitted from the IC tags and are provided so as to correspond to a plurality of positions on the target surface, and the reading unit 130 reads information stored in the IC tag included in the target object 100. In the present embodiment, the reading units 130 correspond to the reading devices 20-1 to 20-30 provided to correspond to the plurality of bays Z1 to Z30 of the game field F. In the case of the modification shown in fig. 21, the reader 20 including antennas (the 1 st antenna 21 and the 2 nd antenna 22) disposed so as to pass through a plurality of positions corresponding to a plurality of positions of the game field F corresponds to the reader 130.

In the case of the card game example described above, the IC tag 73 of the sleeve 70 corresponds to an example of the holding portion 101, the front surface 61 of the card 60 housed in the sleeve 70 corresponds to an example of the [ storage surface ], and the inner side surface of the back surface portion 72 of the sleeve 70 corresponds to an example of the [ holding surface ].

In the case of the card game example described above, the reading unit 130 reads the tag ID (an example of information for identifying the holding unit 101) stored in the IC tag 73 of the card 60S placed in the game field F.

When the association processing shown in fig. 12 is executed, since the card ID of the card 60S (an example of information for identifying the type of the object 100) is stored in the IC tag 73 of the card 60S, the reading unit 130 reads the card ID stored in the IC tag 73 of the card 60S placed in the game field F.

[ 1-6-5 ] the captured image acquisition unit 120 acquires the captured image of the imaging unit 110. The reading result acquisition unit 140 acquires the reading result of the reading unit 130. The specifying unit 150 specifies the type and state of the object 100 placed on the target surface based on the captured image of the imaging unit 110 and the reading result of the reading unit 130. For example, the captured image acquisition unit 120, the read result acquisition unit 140, and the specification unit 150 are realized by the control unit 41 of the information processing device 40.

Determining the type of the object 100 refers to determining which of a plurality of types of objects 100 the object 100 placed on the object surface is. That is, by placing 1 or more objects 100 of the plurality of types of objects 100 on the target surface, it is possible to specify which of the plurality of types of objects 100 at least any one of the objects 100 placed on the target surface corresponds to [ specifying the type of the object 100 ]. For example, identification information for identifying the type of the object 100 is assigned to each object 100, and identification information for identifying the object 100 placed on the object surface corresponds to [ identifying the type of the object 100 ]. In addition, when the object 100 is a game medium stored in the storage body, specifying the type (identification information) of the game medium stored in the storage body corresponds to [ specifying the type of the object 100 ].

The term "specifying the state of the object 100" includes, for example, specifying the position of the object 100 placed on the object surface.

Further, [ specifying the state of the object 100 ] includes, for example, specifying the placement mode (arrangement form) of the object 100 placed on the object surface. Specifically, specifying the orientation of the object 100 placed on the object surface corresponds to an example of [ specifying the state of the object 100 ]. The "orientation" of the object 100 refers to a direction in which the reference direction of the object 100 is oriented.

For example, when the object 100 is a rectangular object, the longitudinal direction of the object 100 corresponds to an example of the [ reference direction ]. In this case, the state of specifying which direction the longitudinal direction of the object 100 is oriented corresponds to an example of [ specifying the orientation of the object 100 ]. For example, the determination of whether the object 100 is placed in a state in which the longitudinal direction of the object 100 is oriented in the 1 st direction or the object 100 is placed in a state in which the longitudinal direction of the object 100 is oriented in the 2 nd direction corresponds to an example of [ determining the orientation of the object 100 ]. More specifically, the determination of whether the object 100 is placed in a portrait orientation (a state in which the object appears vertically long when viewed from a specific viewpoint (such as the player or the imaging unit 110)) or a landscape orientation (a state in which the object 100 appears horizontally long when viewed from a specific viewpoint) corresponds to an example of [ determining the orientation of the object 100 ].

For example, the normal direction of a specific surface (front surface or the like) of the object 100 corresponds to an example of the [ reference direction ]. In this case, a state in which the direction of the normal line of the specific surface (front surface or the like) of the card is specified corresponds to an example of [ specifying the direction of the object 100 ]. For example, the determination of whether the object 100 is placed in a state in which the normal direction is directed to the 1 st direction or the object 100 is placed in a state in which the normal direction is directed to the 2 nd direction corresponds to an example of [ determining the direction of the object 100 ]. More specifically, the case where the object 100 is placed in a state in which the front surface is directed upward (a state in which the front surface is visible from a specific viewpoint) or the object 100 is placed in a state in which the back surface is directed upward (a state in which the back surface is visible from a specific viewpoint: a state in which the front surface and the back surface are reversed) corresponds to an example of [ determining the orientation of the object 100 ].

In addition, for example, in the case where the object 100 is a doll or a single doll stored in a storage body, the front direction of the doll corresponds to an example of the [ reference direction ]. In this case, the determination of which direction the front direction of the doll is oriented corresponds to an example of [ determining the orientation of the object 100 ].

In addition, when the object 100 is a game medium stored in the storage body, specifying the state of the game medium stored in the storage body corresponds to [ specifying the state of the object 100 ].

The term "state of the object 100" specified by the specifying unit 150 refers to a matter that affects the progress or result of the game, among matters that may be included in the term "state of the object 100". In other words, the [ state of the object 100 ] specified by the specification unit 150 is a matter that is meaningful in the progress of the game or a matter that is important to the person who views the display unit 170, among matters that may be included in the term [ state of the object 100 ].

For example, the specifying unit 150 specifies some of the items concerning the type and the state of the object 100 placed on the target surface based on the captured image of the imaging unit 110, and specifies the other items based on the reading result of the reading unit 130.

1-6-6 As shown in FIG. 22, the determination section 150 includes a 1 st determination section 151 and a 2 nd determination section 152.

[ 1-6-6-1 ] the 1 st specifying unit 151 specifies the position of the object 100 placed on the object surface based on the captured image of the imaging unit 110. The 1 st specifying unit 151 specifies the orientation of the object 100 placed on the target surface based on the captured image of the imaging unit 110.

For example, the 1 st determining unit 151 determines the position and orientation of the object 100 placed on the object plane by determining the position and orientation of the object 100 captured in the captured image using a learned model (a model for determining the position and orientation of the object 100 captured in the captured image) generated by performing machine learning based on captured image data including the object plane on which the object 100 is placed and learning data indicating the position and orientation of the object 100.

For example, the 1 st specifying unit 151 may specify the position and orientation of the object 100 placed on the object surface by detecting the object 100 from the captured image of the imaging unit 110 by using image analysis processing. That is, the 1 st specifying unit 151 may specify the position and orientation of the object 100 placed on the object surface by detecting the object 100 from the captured image based on the feature information of the appearance of the object 100, and specifying the position and orientation of the object 100 captured in the captured image.

In the case of the card game example described above, the 1 st specifying unit 151 specifies the position of the card 60S from the captured image of the imaging device 30. The 1 st specifying unit 151 specifies the vertical and horizontal orientations of the card 60S based on the captured image of the imaging device 30. The 1 st specifying unit 151 specifies the orientation of the front and back surfaces of the card 60S based on the captured image of the imaging device 30.

[ 1-6-6-2 ] the 2 nd specifying unit 152 specifies the position of the object 100 placed on the object surface based on the reading result of the reading unit 130. The 2 nd specifying unit 152 specifies the type of the object 100 placed on the object surface based on the reading result of the reading unit 130. The 2 nd specifying unit 152 specifies information described on the recording surface of the object 100 placed on the object surface, based on the reading result of the reading unit 130. For example, the 2 nd specifying unit 152 specifies the information described on the recording surface of the object 100 placed on the target surface based on the result of specifying the type of the object 100 placed on the target surface.

The reading result of the reading unit 130 refers to information read by the reading unit 130. The "reading result of the reading unit 130" may be information on whether or not the information held by the holding unit 101 can be read.

When the holding unit 101 is an IC tag and the reading unit 130 includes a plurality of antennas, the [ reading result of the reading unit 130 ] may be information on which antenna among the plurality of antennas that receive the signal transmitted from the IC tag of the object placed on the object surface is to receive the signal transmitted from the IC tag, and the plurality of antennas may be provided so as to correspond to a plurality of positions on the object surface. For example, in the case where the reading unit 130 includes a plurality of IC tag readers provided at a plurality of positions corresponding to a plurality of positions of the target surface, the [ reading result of the reading unit ] may be information on which IC reader of the plurality of IC readers has read the information stored in the IC tag. For another example, when the reading unit 130 includes an IC tag reader having antennas arranged to pass through a plurality of positions on the target surface, [ reading result of the reading unit ] may be information on which part of the antenna the signal from the IC tag is received.

In the case of the above-described example of the card game, the information read by the reader 20 (the information stored in the IC tag 73) corresponds to an example of [ the reading result of the reading unit 130 ]. The information as to whether or not the reader 20 has read the information stored in the IC tag 73 corresponds to an example of [ reading result of the reading unit 130 ]. Further, information on which reading device of the plurality of reading devices 20-1 to 20-30 has read the information stored in the IC tag 73 (in other words, which reading device of the plurality of reading devices 20-1 to 20-30 has received the signal from the IC tag 73) corresponds to an example of [ reading result of the reading unit 130 ]. In the case of the modification shown in fig. 21, the information on which of the 1 st antenna 21 and the 2 nd antenna 22 the signal from the IC tag 73 is received corresponds to an example of [ reading result of the reading unit 130 ].

In the case of the card game example described above, the 2 nd specifying unit 152 specifies the position and the type of the card 60S placed on the field F based on the reading result of the reading device 20.

For example, the 2 nd specifying unit 152 specifies the position of the card 60S based on which reading device 20 has read the information stored in the IC tag 73 of the card 60S. That is, the 2 nd specifying unit 152 specifies, as the position of the card 60S, the position on the game field F corresponding to the position of the reader 20 (the reader 20 that received the signal transmitted from the IC tag 73 of the card 60S) that has read the information stored in the IC tag 73 of the card 60S. For example, in a case where the reader 20-10 reads information stored in the IC tag 73 of the card 60S, the 2 nd determination section 152 determines the division Z10 associated with the reader 20-10 as the division Z on which the card 60S is placed.

In the case of the modification shown in fig. 21, the 2 nd specifying unit 152 may specify the position of the card 60S based on which part of the antenna the signal from the IC tag 73 of the card 60S is received. That is, the 2 nd specifying unit 152 may specify, as the position of the card 60S, the position on the game field F corresponding to the portion of the antenna that receives the signal from the IC tag 73 of the card 60S. For example, the 2 nd specifying unit 152 may specify the section Z including the intersection of the 1 st antenna 21 and the 2 nd antenna 22 (in other words, the 1 st antenna 21 and the 2 nd antenna 22 having the strongest received signal strength) which have received the signal from the IC tag 73 of the card 60S, as the section Z on which the card 60S is placed.

The 2 nd determining unit 152 determines the type of the card 60S placed in the game field F based on the information read by the reading device 20.

For example, when the association processing shown in fig. 10 is executed, the storage unit 42 stores association data D1 (fig. 11) in which the tag ID and the card ID are associated with each other. At this time, the 2 nd determination section 152 determines the card ID associated with the tag ID read by the reading device 20, based on the associated data D1.

For example, when the association process shown in fig. 12 is executed, the card ID of the card 60S is stored in the IC tag 73 of the card 60S, and the card ID is read by the reading unit 130. At this time, the 2 nd specifying unit 152 acquires the card ID read by the reading device 20.

[ 1-6-6-3 ] there may be a case where a plurality of objects 100 are placed on a target surface. In this case, the 1 st specifying unit 151 obtains a result of the specification based on the captured image of the imaging unit 110 for each of the plurality of objects 100. Similarly, the 2 nd specification unit 152 obtains a result of the specification based on the reading result of the reading unit 130 for each of the plurality of objects 100. In such a case, it is necessary to specify a combination of the determination result of the 1 st specifying unit 151 and the determination result of the 2 nd specifying unit 152 with respect to the same object 100 placed on the object surface.

In this regard, the determination result of the 1 st determining unit 151 and the determination result of the 2 nd determining unit 152 commonly include determination results regarding predetermined matters of the object 100, and the determining unit 150 determines a combination of the determination result of the 1 st determining unit 151 and the determination result of the 2 nd determining unit 152 regarding the same object 100 placed on the object surface by comparing the determination result of the 1 st determining unit 151 and the determination result regarding the predetermined matters commonly included in the determination results of the 2 nd determining unit 152.

In the present embodiment, since the determination result of the 1 st determining unit 151 and the determination result of the 2 nd determining unit 152 collectively include the determination result regarding the position of the object 100 (an example of the above-described predetermined matter), the determining unit 150 determines the combination of the determination result of the 1 st determining unit 151 and the determination result of the 2 nd determining unit 152 regarding the same object 100 placed on the object surface, based on the position determined by the 1 st determining unit 151 and the position determined by the 2 nd determining unit 152.

That is, the determination section 150 determines the determination result of the 1 st determination section 151 and the determination result of the 2 nd determination section 152 as the determination results regarding the same object 100 placed on the object surface based on the comparison of the position determined by the 1 st determination section 151 and the position determined by the 2 nd determination section 152.

In other words, in the case where the position specified by the 1 st specifying unit 151 corresponds to the position specified by the 2 nd specifying unit 152, the specifying unit 150 determines that the combination of the kind specified by the 1 st specifying unit 151 and the orientation specified by the 2 nd specifying unit 152 is a result of the determination regarding the same object 100 placed on the object surface.

The case where the position specified by the 1 st specifying unit 151 corresponds to the position specified by the 2 nd specifying unit 152 refers to a case where it can be regarded that the position specified by the 1 st specifying unit 151 is the same as the position specified by the 2 nd specifying unit 152, and for example, it may be said that the position specified by the 1 st specifying unit 151 and the position specified by the 2 nd specifying unit 152 both correspond to the same area.

For example, in the above-described example of the card game, a plurality of divisions Z1 to Z30 (partial areas) are defined in the field F as areas for placing the cards 60S, and the plurality of reading devices 20-1 to 20-30 are provided corresponding to the plurality of divisions Z1 to Z30. When the card 60S is placed in any one of the zones Z, which zone Z the card 60 is placed in is determined from the captured image of the imaging device 30. In addition, in addition to this, it is determined in which zone Z the card 60 is placed, based on the reading result of the reading device 20. That is, the partition Z corresponding to the reading device 20 that reads the information stored in the IC tag 73 of the card 60S is determined as the partition Z where the card 60S is placed. The [ case where the position specified by the 1 st specifying unit 151 corresponds to the position specified by the 2 nd specifying unit 152 ] in this case refers to a case where the precinct Z specified from the captured image of the imaging device 30 is the same as the precinct Z specified from the reading result of the reading device 20.

Note that [ the case where the position specified by the 1 st specifying unit 151 corresponds to the position specified by the 2 nd specifying unit 152 ] may be a case where the distance between the position specified from the captured image of the imaging unit 110 and the position specified from the reading result of the reading unit 130 is smaller than a threshold value.

1-6-6-4 the 2 nd identification unit 152 can identify the type of the card 60S (1 st card) placed on the game field F in a state where another card 60S (2 nd card) is stacked, based on the information read by the reading unit 130 from the IC tag 73 of the card 60S (1 st card). For example, as in the situation shown in fig. 7, even when the card set 600-1 is placed in the partition Z7, the 2 nd specifying unit 152 can specify the type of each of the plurality of cards 60S included in the card set 600-1 based on the information read by the reading unit 130 from the IC tags 73 of each of the plurality of cards 60S.

[ 1-6-7 ] the display control unit 160 causes the display unit 170 to display an object (object) corresponding to the object 100 placed on the object plane. For example, the display control unit 160 is realized by at least one of the control unit 41 of the information processing apparatus 40 and the control unit 51 of the display terminal apparatus 50. The display unit 170 is implemented by at least one of the display unit 45 of the information processing apparatus 40 and the display unit 55 of the display terminal apparatus 50.

The [ object ] is an object displayed on the display unit 170. For example, [ object ] is an object that mimics the object 100. That is, the "target" is a target obtained by imaging the object 100. The [ object ] may be an object (text, icon, or the like) indicating the type and name of the object 100, or the content of the influence on the progress or result of the game.

For example, the display control unit 160 causes the display unit 170 to display an object corresponding to the type of the object 100 specified by the specifying unit 150 in a state corresponding to the state of the object 100 specified by the specifying unit 150. Specifically, the display control unit 160 causes the display position corresponding to the position of the object 100 (the position on the object plane) specified by the specifying unit 150 to display the target corresponding to the type of the object 100 specified by the specifying unit 150. Further, the display control unit 160 causes the target corresponding to the type of the object 100 specified by the specifying unit 150 to be displayed in the orientation corresponding to the orientation of the object 100 specified by the specifying unit 150.

For example, the display control unit 160 causes the display unit 170 to display an object corresponding to the type of the object 100 specified by the specifying unit 150, based on the state of the object 100 specified by the specifying unit 150.

Specifically, the display control unit 160 determines whether or not to display the object corresponding to the type of the object 100 specified by the specifying unit 150 on the display unit 170 as the object corresponding to the object 100, based on the state of the object 100 specified by the specifying unit 150.

That is, the display control unit 160 determines whether or not the state of the object 100 specified by the specifying unit 150 is a predetermined state. When it is determined that the state of the object 100 specified by the specifying unit 150 is not the predetermined state, the display control unit 160 causes the display unit 170 to display the object corresponding to the type of the object 100 specified by the specifying unit 150 as the object corresponding to the object 100. On the other hand, when determining that the state of the object 100 specified by the specifying unit 150 is the predetermined state, the display control unit 160 does not display the object corresponding to the type of the object 100 specified by the specifying unit 150 on the display unit 170 as the object corresponding to the object 100. In this case, the display control unit 160 causes the display unit 170 to display an object that is not related to the type of the object 100 specified by the specifying unit 150 as an object corresponding to the object 100.

Further, when the object 100 is placed on the target surface such that the above-described recording surface (information-bearing surface) of the object 100 faces the target surface, the display control unit 160 causes the display unit 170 to display a display corresponding to the information described on the recording surface of the object 100 specified by the specifying unit 150 (the 2 nd specifying unit 152).

The case where the object 100 is placed on the target surface so that the recording surface faces the target surface means the case where the object 100 is placed on the target surface so that the recording surface is not visible from the imaging unit 110.

For example, when the object 100 is a game medium stored in the storage body, [ the object 100 is placed on the object surface so that the recording surface faces the object surface ] means that the object 100 is placed on the object surface so that the recording surface of the game medium faces the object surface with the storage body therebetween. In other words, the object 100 is placed on the object surface so that the recording surface of the game medium and the object surface contact each other with the storage body interposed therebetween.

In addition, when the object 100 is a game medium alone, the phrase "when the object 100 is placed on the object surface so that the recording surface faces the object surface" means that the object 100 (game medium) is placed on the object surface so that the recording surface of the game medium is in contact with the object surface.

The display unit 170 displays the display corresponding to the information described on the description surface, for example, the display unit 170 displays the information described on the description surface of the object 100. In this case, all the information described on the description surface may be displayed on the display unit 170, or a part of the information described on the description surface may be displayed on the display unit 170.

Specifically, [ causing display corresponding to information described on the description surface to be displayed on the display unit 170] means causing a target that mimics the description surface of the object 100 to be displayed on the display unit 170. In other words, the display unit 170 displays an object obtained by imaging the recording surface of the object 100.

For example, when the type of the object 100 or the content of the influence on the progress or the result of the game is described on the description surface, [ the display 170 is displayed in accordance with the information described on the description surface ] may be displayed on the display 170 in the form of text, a pattern, or the like indicating the type of the object 100 or the content of the influence on the progress or the result of the game. In this case, the display method of the type of the object, the content that affects the progress or the result of the game, and the like in the display unit 170 may be different from the display method in the recording surface.

For example, in the case where the type of the object 100 is described on the recording surface, [ causing the display unit 170 to display the display corresponding to the information described on the recording surface ] may mean causing the display unit 170 to display a text, a pattern, or the like that is not described on the recording surface and that indicates an item (for example, a content of an influence of the object 100 on the progress or the result of the game) specified according to the type of the object 100.

Note that the phrase "causing the display unit 170 to display a display corresponding to the information described on the description surface" may mean that the display unit 170 transmits data relating to a display corresponding to the information described on the description surface to another device, and causes the display unit 170 to display a display corresponding to the information described on the description surface on the other device.

At least when the object 100 is placed on the object surface so that the recording surface faces the object surface, the display control unit 160 causes the display unit 170 to display a display corresponding to the information recorded on the recording surface of the object 100 specified by the specifying unit 150 (the 2 nd specifying unit 152).

In a case where the object 100 is placed on the object surface so that the recording surface does not face the object surface (that is, in a case where the object 100 is placed on the object surface in a state where the recording surface is visible), the display control unit 160 may cause the display unit 170 to display a display corresponding to the information described on the recording surface of the object 100 specified by the specifying unit 150 (the 2 nd specifying unit 152), or in this case, may cause the display unit 170 to display a display corresponding to the information described on the recording surface of the object 100 specified by another specifying method. For example, in a case where the object 100 is placed on the object surface so that the recording surface does not face the object surface (that is, in a case where the object 100 is placed on the object surface in a state where the recording surface is visible), information recorded on the recording surface of the object 100 may be read, and a display corresponding to the read information may be displayed on the display unit 170. For example, when the object 100 is placed on the object surface in a state where the recording surface is captured in the captured image of the imaging unit 110, information recorded on the recording surface of the object 100 may be specified from the captured image of the imaging unit 110, and a display corresponding to the specified information may be displayed on the display unit 170.

Further, when a predetermined operation is received with respect to the object 100 in a state where the object 100 is placed on the object surface such that the recording surface faces the object surface, the display control unit 160 may cause the display unit 170 to display a display corresponding to the information recorded on the recording surface of the object 100.

The [ prescribed operation ] is, for example, an operation of specifying (or selecting) a target. The [ predetermined operation ] may be an operation for specifying the type, position, or orientation of any one of the targets as long as the operation is used to specify the target. Based on such an operation, a target corresponding to the specified kind, position, or orientation is determined. For example, based on such an operation, a process of displaying a display corresponding to information described on the recording surface of the object 100 corresponding to the target on the display unit 170 is performed.

In the case of the above-described card game example, the parts PB-1 and PB-2 shown in fig. 8 correspond to an example of [ object ], and the part PC shown in fig. 9 corresponds to an example of [ display corresponding to information described on the description surface ]. In the case of the above-described example of the card game, the display control unit 160 causes the display unit 170 to display the game field image G.

For example, the display control portion 160 determines whether the orientation of the card 60S determined by the 1 st determining portion 151 is right-side up or back-side up.

When the orientation of the card 60S specified by the 1 st specifying unit 151 is right-side-up, the display control unit 160 causes the image of the front surface 61 of the card 60S (i.e., the image corresponding to the type of the card 60S specified by the 2 nd specifying unit 152) such as the portion PB-2 shown in fig. 8 to be displayed at a position within the game field image G corresponding to the position of the card 60S specified by the 1 st specifying unit 151 or the 2 nd specifying unit 152 as a portion associated with the card 60S.

On the other hand, when the orientation of the card 60S specified by the 1 st specifying unit 151 is such that the back surface faces upward, the display control unit 160 does not display, as a portion associated with the card 60S, an image of the front surface 61 of the card 60S (i.e., an image corresponding to the type of the card 60S specified by the 2 nd specifying unit 152) as in the portion PB-2 shown in fig. 8, but instead displays an image of the back surface 62 of the card 60S (i.e., an image unrelated to the type of the card 60S specified by the 2 nd specifying unit 152) as in the portion PB-1 shown in fig. 8 at a position within the game field image G corresponding to the position of the card 60S specified by the 1 st specifying unit 151 or the 2 nd specifying unit 152.

The display control unit 160 causes the portion PC indicating the front surface 61 of the card 60S to be displayed in response to a designation operation for a portion associated with the card 60S placed with the back surface facing upward, such as the portion PB-1 shown in fig. 8.

Embodiment 2 the following describes embodiment 2 of the present invention.

The difference between embodiment 2 and embodiment 1 is that the card orientation (vertical and horizontal orientation) is determined based on information stored in the IC tag. The following description deals with differences from embodiment 1. Hereinafter, the same elements as those of embodiment 1 are denoted by the same reference numerals, and description thereof will be omitted.

Fig. 23 shows an example of a sleeve 70A according to embodiment 2. As with the sleeve 70 of embodiment 1, the front face portion 71A of the sleeve 70A is transparent, and the front face 61 of the card 60 housed in the sleeve 70A can be visually recognized from the outside of the sleeve 70A. In addition, as with the sleeve 70 of embodiment 1, the back surface portion 72A of the sleeve 70A is opaque, and all the sleeves 70A have the same appearance.

As shown in fig. 23, the sleeve 70A contains a 1 st IC tag 73A-1 and a 2 nd IC tag 73A-2. The 1 st IC tag 73A-1 and the 2 nd IC tag 73A-2 are provided on the inner side surface of the back surface portion 72A. For example, the 1 st IC tag 73A-1 and the 2 nd IC tag 73A-2 on the inner surface of the back portion 72A are disposed at different positions. For example, the 1 st IC tag 73A-1 and the 2 nd IC tag 73A-2 are set to be disposed at positions different from each other in the 1 st direction (for example, the longitudinal direction) and the 2 nd direction (for example, the lateral direction) between the positions.

The 1 st IC tag 73A-1 stores the tag ID of the 1 st IC tag 73A-1, and the 2 nd IC tag 73A-2 stores the tag ID of the 2 nd IC tag 73A-2. Since the 1 st IC tag 73A-1 and the 2 nd IC tag 73A-2 are independent IC tags, their tag IDs are different from each other.

In embodiment 2, the card 60 is accommodated in the sleeve 70A as described above. Hereinafter, the card 60 stored in the sleeve 70A will be referred to as "card 60 SA" for convenience, in order to distinguish it from the card 60 alone. In other words, the card 60 and the sleeve 70A when the card 60 is accommodated in the sleeve 70A are regarded as one object and are described as [ card 60SA ].

In embodiment 2, in order to specify the positions of the 1 st IC tag 73A-1 and the 2 nd IC tag 73A-2 of the card 60SA placed on the game field F, the reader 20 is provided with a plurality of antennas that receive signals transmitted from the 1 st IC tag 73A-1 and the 2 nd IC tag 73A-2, respectively, and that are provided so as to correspond to the plurality of positions on the game field F. For example, in embodiment 2, a reader 20 having a plurality of 1 st antennas 21 and a plurality of 2 nd antennas 22 shown in fig. 21 is provided.

That is, in the case where the card 60SA is placed on the game field F, the position of the 1 st IC tag 73A-1 on the game field F can be determined by determining the combination of the 1 st antenna 21 and the 2 nd antenna 22 that received the signal from the 1 st IC tag 73A-1 (the ID tag of the 1 st IC tag 73A-1) (in other words, the combination of the 1 st antenna 21 and the 2 nd antenna 22 that received the signal from the 1 st IC tag 73A-1 with the strongest intensity). For example, the intersection of the 1 st antenna 21 and the 2 nd antenna 22 (in other words, the 1 st antenna 21 and the 2 nd antenna 22 having the strongest received signal strength) which have received the signal from the 1 st IC tag 73A-1 can be determined as the position of the 1 st IC tag 73A-1 on the game field F.

Similarly, the position of the 2 nd IC tag 73A-2 on the field F can be determined by determining the combination of the 1 st antenna 21 and the 2 nd antenna 22 (the combination of the 1 st antenna 21 and the 2 nd antenna 22 having the strongest signal received from the 2 nd IC tag 73A-2) which has received the signal from the 2 nd IC tag 73A-2 (the ID tag of the 2 nd IC tag 73A-2).

Fig. 24 shows a case where the card 60SA is placed in the vertical direction at the playard F, and fig. 25 shows a case where the card 60SA is placed in the horizontal direction at the playard F. Here, a coordinate system is assumed in which a predetermined point (for example, a lower left point) of the field F is set as an origin O, a lateral direction of the field F is set as an X-axis direction, and a vertical direction of the field F is set as a Y-axis direction, as shown in fig. 24 and 25. The position of the 1 st IC tag 73A-1 on the field F is (X1, Y1), and the position of the 2 nd IC tag 73A-2 on the field F is (X2, Y2).

As shown in fig. 24, when the card 60SA is placed in the vertical direction, the longitudinal direction of the card 60SA is parallel (or substantially parallel) to the Y-axis direction, and the card 60SA is vertically long. In this case, the absolute value of the difference between Y1 and Y2 (| Y1-Y2 |) is greater than the absolute value of the difference between X1 and X2 (| X1-X2 |). Therefore, in the case where the determined positions of the 1 st IC tag 73A-1 and the 2 nd IC tag 73A-2 have the relationship of | Y1-Y2 | > | X1-X2 |, it can be determined that the card 60SA is placed in a longitudinal manner.

On the other hand, as shown in fig. 25, when the card 60SA is placed in the lateral direction, the longitudinal direction of the card 60SA is parallel (or substantially parallel) to the X-axis direction, and the card 60SA is horizontally long. In this case, the absolute value of the difference between X1 and X2 (| X1-X2 |) is greater than the absolute value of the difference between Y1 and Y2 (| Y1-Y2 |). Therefore, in the case where the determined positions of the 1 st IC tag 73A-1 and the 2 nd IC tag 73A-2 have a relationship of | X1-X2 | > | Y1-Y2 |, it can be determined that the card 60SA is placed in a lateral manner.

As described above, in embodiment 2, the positions of the 1 st IC tag 73A-1 and the 2 nd IC tag 73A-2 are determined based on the reading result of the reading device 20, and the vertical and horizontal orientations of the card 60SA can be determined based on the positional relationship between them.

Processing the processing executed by the system 1A of embodiment 2 will be described below.

[ 2-2-1 ] in embodiment 2, the association processing similar to that shown in fig. 10 is also executed. However, in step S404, the control unit 41 acquires the tag IDs of the 1 st IC tag 73A-1 and the 2 nd IC tag 73A-2, and in step S406, the control unit 41 registers the tag IDs of both the 1 st IC tag 73A-1 and the 2 nd IC tag 73A-2 in the [ tag ID ] field of the related data D1.

[ 2-2-2 ] in embodiment 2, a correlation process similar to the correlation process shown in fig. 12 may also be performed. However, in step S424, the control section 41 writes the card ID determined in step S422 to both the 1 st IC tag 73A-1 and the 2 nd IC tag 73A-2.

2-2-3 in embodiment 2, determination processing similar to that shown in fig. 13 is also executed.

In embodiment 2, in step S432, the control unit 41 specifies the position of the card 60SA and the front and back surfaces, and does not specify the longitudinal and transverse orientations of the card 60 SA. At this time, the determination result in step S432 is registered in the 1 st determination result data D2A. Fig. 26 shows an example of the 1 st determination result data D2A in embodiment 2. As shown in fig. 26, the 1 st determination result data D2A contains [ area ID ] and [ front and back label ] fields. The [ area ID ] and [ front and back side mark ] fields are the same as the [ area ID ] and [ front and back side mark ] fields of the 1 st determination result data D2 of embodiment 1.

In embodiment 2, in step S436, the control unit 41 specifies the card ID, the position, and the vertical and horizontal orientations of the card 60SA placed on the field F.

For example, the control section 41 refers to the related data D1 to determine the card ID associated with the tag ID read from the 1 st IC tag 73A-1 and the tag ID read from the 2 nd IC tag 73A-2.

When the tag ID read from the 1 st IC tag 73A-1 and the ID tag read from the 2 nd IC tag 73A-2 are associated with the same card ID, the control unit 41 regards the 1 st IC tag 73A-1 and the 2 nd IC tag 73A-2 as tags included in the same card 60 SA. The control unit 41 executes the processing described below with respect to the 1 st IC tag 73A-1 and the 2 nd IC tag 73A-2 provided on the same card 60 SA.

That is, the control unit 41 identifies the position of the 1 st IC tag 73A-1 on the game field F by identifying the combination of the 1 st antenna 21 and the 2 nd antenna 22 that received the signal (tag ID) from the 1 st IC tag 73A-1 (in other words, the combination of the 1 st antenna 21 and the 2 nd antenna 22 that received the signal from the 1 st IC tag 73A-1 having the strongest intensity).

Similarly, the control unit 41 identifies the combination of the 1 st antenna 21 and the 2 nd antenna 22 that received the signal (tag ID) from the 2 nd IC tag 73A-2 (in other words, the combination of the 1 st antenna 21 and the 2 nd antenna 22 that received the signal from the 2 nd IC tag 73A-2 having the strongest strength), thereby identifying the position of the 2 nd IC tag 73A-2 on the game field F.

Then, the control section 41 specifies the midpoint between the position of the 1 st IC tag 73A-1 and the position of the 2 nd IC tag 73A-2 as the position of the card 60SA, and determines which zone Z the specified position is included in, thereby specifying the zone Z on which the card 60SA is placed.

Further, the control unit 41 specifies the longitudinal and lateral directions of the card 60SA based on the positional relationship between the position of the 1 st IC tag 73A-1 and the position of the 2 nd IC tag 73A-2.

For example, in the case where the difference in the longitudinal direction (| Y2-Y1 |) between the position of the 1 st IC tag 73A-1 and the position of the 2 nd IC tag 73A-2 is larger than the difference in the lateral direction (| X2-X1 |), the control section 41 determines that the card 60SA is placed in the longitudinal direction. On the other hand, in the case where the difference in the longitudinal direction (| Y2-Y1 |) between the position of the 1 st IC tag 73A-1 and the position of the 2 nd IC tag 73A-2 is smaller than the difference in the lateral direction (| X2-X1 |), the control section 41 determines that the card 60SA is placed in the lateral direction.

In the 2 nd embodiment, the determination result in step S436 is registered in the 2 nd determination result data D3A. Fig. 27 shows an example of the 2 nd determination result data D3A. As shown in fig. 27, the 2 nd determination result data D3A contains [ partition ID ], [ card ID ], and [ cross-bar ] fields. The [ partition ID ] field is the same as the [ partition ID ] field of the field situation data D4 of embodiment 1. The [ card ID ] field is the same as the [ card ID ] field of the 2 nd determination result data D3 of embodiment 1. The [ vertical and horizontal flag ] field is the same as the [ vertical and horizontal flag ] field of the 1 st determination result data D2 of embodiment 1.

In addition, in embodiment 2, in step S438, the control unit 41 generates the field situation data D4 from the 1 st and 2 nd determination result data D2A and D3A. The playground situation data D4 is the same as in embodiment 1. The processing of step S438 is the same as that of step S438 of embodiment 1, except that the vertical and horizontal marks registered in the vertical and horizontal mark field of the 2 nd determination result data D3A are registered in the vertical and horizontal mark field of the field situation data D4.

2-2-4 in embodiment 2, the display control process shown in fig. 18 and the process shown in fig. 19 are also executed.

Effect 2-3 according to embodiment 2, the longitudinal and lateral directions of the card 60SA placed on the playard F can be determined based on the reading result of the reading device 20.

Modifications of embodiment 2 will be described below in detail with reference to [ 2-4 ] modifications.

[ 2-4-1 ] in the above-described embodiment, the arrangement positions of the 1 st IC tag 73A-1 and the 2 nd IC tag 73A-2 are not limited to the example shown in FIG. 23. The positions of the 1 st IC tag 73A-1 and the 2 nd IC tag 73A-2 may be set to have a positional relationship such that the longitudinal and transverse directions of the card 60SA can be determined from the positional relationship if the positions of the 1 st IC tag 73A-1 and the 2 nd IC tag 73A-2 of the card 60SA placed on the field F can be determined.

For example, the 1 st IC tag 73A-1 may be provided at the upper left position on the back surface portion 72A, and the 1 st IC tag 73A-2 may be provided at the upper right position on the back surface portion 72A. For example, the 1 st IC tag 73A-1 may be provided at the upper left position on the back surface portion 72A, and the 1 st IC tag 73A-2 may be provided at the lower left position on the back surface portion 72A.

[ 2-4-2 ] in addition to the 1 st IC tag 73A-1 and the 2 nd IC tag 73A-2, 1 or more IC tags may be provided on the back surface portion 72A. That is, 3 or more IC tags may be provided on the back surface portion 72A, and the longitudinal and transverse directions of the card 60SA may be determined based on the positional relationship of the 3 or more IC tags.

In embodiment 2, the control unit 41 may determine the longitudinal and transverse directions of the card 60SA in step S432. That is, the control section 41 may determine the longitudinal and transverse directions of the card 60SA from the captured image of the imaging device 30 and also determine the longitudinal and transverse directions of the card 60SA from the reading result of the reading device 20. In this case, by collating the determination result of the vertical and horizontal directions obtained from the captured image of the imaging device 30 with the determination result of the vertical and horizontal directions obtained from the reading result of the reading device 20, the accuracy of the determination result of the vertical and horizontal directions can be improved.

[ 2-4-4 ] in the above-described embodiment, the sleeve 70A (the back surface portion 72A) is provided with the 1 st IC tag 70A-1 and the 2 nd IC tag 70A-2, but a sheet-like object housed in the sleeve 70A together with the card 60, such as the object 80 shown in FIG. 20, may be provided with the 1 st IC tag 70A-1 and the 2 nd IC tag 70A-2. In this case, the sheet-like object and the object in which the card 60 is accommodated in the sleeve 70A correspond to the card 60 SA.

[ 2-4-5 ] the card 60 itself (e.g., the back surface 62) may be provided with the 1 st IC tag 70A-1 and the 2 nd IC tag 70A-2.

Fig. 28 is a functional block diagram for explaining functional elements included in the system 1A according to embodiment 2. In fig. 28, the same functional elements as those of embodiment 1 (the image pickup unit 110, the captured image acquisition unit 120, the reading unit 130, the reading result acquisition unit 140, the display control unit 160, and the display unit 170) are denoted by the same reference numerals as those of fig. 22, and the description of these functional elements is omitted here, and the subject 100A and the specification unit 150A are described. Note that description of the words and phrases is omitted for the points overlapping with embodiment 1.

[ 2-5-1 ] first, the object 100A will be described. Here, differences between the object 100A and the object 100 in embodiment 1 will be described.

The object 100A includes a 1 st holding portion 101A and a 2 nd holding portion 102A provided so as to have a predetermined positional relationship with the 1 st holding portion 101A. The 1 st holding unit 101A and the 2 nd holding unit 102A have a positional relationship in which the orientation of the object 100A can be specified from the positions of the 1 st holding unit 101A and the 2 nd holding unit 102A of the object 100A placed on the object surface if the positions can be specified. For example, when the object 100A is placed on the object surface in the 1 st orientation, the positional relationship between the 1 st holding part 101A and the 2 nd holding part 102A on the object surface is the 1 st positional relationship, and when the object 100A is placed on the object surface in the 2 nd orientation different from the 1 st orientation, the positional relationship between the 1 st holding part 101A and the 2 nd holding part 102A on the object surface is the 2 nd positional relationship different from the 1 st positional relationship, and the positions of the 1 st holding part 101A and the 2 nd holding part 102A in the object 100A are set.

Identification information for identifying the type or state of the object 100A placed on the object surface is held in the 1 st holding unit 101A and the 2 nd holding unit 102A. The information held in the 1 st holding unit 101A and the 2 nd holding unit 102A is read by the reading unit 130. In the present embodiment, the 1 st IC tag 73A-1 corresponds to the 1 st holding portion 101A, and the 2 nd IC tag 73A-2 corresponds to the 2 nd holding portion 102A.

[ 2-5-2 ] the specification section 150A will be described. The determination section 150A includes a 1 st determination section 151A and a 2 nd determination section 152A.

The 1 st specifying unit 151A specifies the position and orientation of the object 100A based on the captured image of the imaging unit 110. For example, the 1 st specifying unit 151A specifies the position and the front-back direction of the object 100A, as in the 1 st specifying unit 151 of embodiment 1.

The 2 nd specifying unit 152A specifies the position, the type, and the orientation of the object 100A based on the reading result of the reading unit 130.

The 2 nd specifying unit 152A specifies the type of the object 100A in the same manner as the 2 nd specifying unit 152 of the 1 st embodiment.

As described above, in embodiment 2, the reading unit 130 includes a plurality of antennas (the plurality of 1 st antennas 21 and the plurality of 2 nd antennas 22) that receive signals transmitted from the 1 st holding unit 101A (the 1 st IC tag 73A-1) and the 2 nd holding unit 102A (the 2 nd IC tag 73A-2), respectively, and that are provided so as to correspond to a plurality of positions on the game field F, respectively.

The 2 nd specifying unit 152A specifies the position and the orientation of the object 100A placed on the object surface based on which of the plurality of antennas the signals transmitted from the 1 st holding unit 101A (the 1 st IC tag 73A-1) and the 2 nd holding unit 102A (the 2 nd IC tag 73A-2) of the object 100A placed on the object surface are received.

In order to distinguish between signals received by the antenna and signals transmitted from either the 1 st holding unit 101A or the 2 nd holding unit 102A, the information held by the 1 st holding unit 101A and the 2 nd holding unit 102A includes different information, and the signals transmitted from the 1 st holding unit 101A and the 2 nd holding unit 102A include different information. For example, the identification information of the 1 st holding unit 101A (the tag ID of the 1 st IC tag 73A-1) is held in the 1 st holding unit 101A (the 1 st IC tag 73A-1), and the identification information of the 2 nd holding unit 102A (the tag ID of the 2 nd IC tag 73A-2) is held in the 2 nd holding unit 102A (the 2 nd IC tag 73A-2).

[ 2-5-3 ] in the case of the above-described example of the card game, the card 60SA corresponds to the object 100A. In the case of the modified example in which the card 60 itself includes the 1 st IC tag 73A-1 and the 2 nd IC tag 73A-2, the card 60 alone corresponds to the object 100A.

The 2 nd determining section 152A determines the position of the 1 st IC tag 73A-1 on the game field F by determining the combination of the 1 st antenna 21 and the 2 nd antenna 22 that received the signal from the 1 st IC tag 73A-1 (the tag ID of the 1 st IC tag 73A-1) placed on the card 60SA on the game field F (the combination of the 1 st antenna 21 and the 2 nd antenna 22 that received the signal from the 1 st IC tag 73A-1 with the strongest intensity). Similarly, the 2 nd determination unit 152A determines the position of the 2 nd IC tag 73A-2 on the game field F by determining the combination of the 1 st antenna 21 and the 2 nd antenna 22 (the combination of the 1 st antenna 21 and the 2 nd antenna 22 having the strongest signal intensity received from the 2 nd IC tag 73A-2) that received the signal from the 2 nd IC tag 73A-2 (the tag ID of the 2 nd IC tag 73A-2) of the card 60SA placed on the game field F. Then, the 2 nd specifying unit 152A specifies the longitudinal and lateral directions of the card 60SA based on the positional relationship between the 1 st IC tag 73A-1 and the 2 nd IC tag 73A-2 on the game field F.

In this way, in embodiment 2, since the positions of the 1 st IC tag 73A-1 and the 2 nd IC tag 73A-2 on the field F are determined from the tag ID of the 1 st IC tag 73A-1 stored in the 1 st IC tag 73A-1 and the tag ID of the 2 nd IC tag 73A-2 stored in the 2 nd IC tag 73A-2, and the longitudinal and transverse directions of the card 60SA are determined from the positional relationship between the 1 st IC tag 73A-1 and the 2 nd IC tag 73A-2 on the field F, the tag ID of the 1 st IC tag 73A-1 and the tag ID of the 2 nd IC tag 73A-2 correspond to [ information as a basis for determining the state of the object 100A ].

[3 ] embodiment 3 of the present invention will be explained.

The embodiment 3 is different from the embodiment 1 in that the card orientation (front-back direction) is specified based on the information stored in the IC tag. The following description deals with differences from embodiment 1. In the following description, the same elements as those of embodiment 1 are denoted by the same reference numerals, and descriptions thereof are omitted.

[ 3-1 ] overview FIG. 29 shows an example of a sleeve 70B according to embodiment 3. Fig. 29 shows a cross-sectional view of the sleeve 70B when the sleeve 70B is viewed from the side. As with the sleeve 70 of embodiment 1, the front face portion 71B of the sleeve 70B is transparent, and the front face 61 of the card 60 housed in the sleeve 70B can be visually recognized from the outside of the sleeve 70B. In addition, the back surface portion 72B of the sleeve 70B is opaque, and all the sleeves 70B have a common appearance, as in the sleeve 70 of embodiment 1.

As shown in fig. 29, the sleeve 70B includes a 1 st IC tag 73B-1, a 2 nd IC tag 73B-2, and a blocking face portion 74B. For example, the blocking face portion 74B has the same (or substantially the same) shape and size as the back portion 72B of the sleeve 70B. The upper end and the lower end of the blocking surface portion 74B are connected to the upper end and the lower end of the back surface portion 72B, and the blocking surface portion 74B is fixed to the sleeve 70B.

The 1 st surface 75B of the blocking surface portion 74B faces the front surface portion 71B of the sleeve 70B. The 1 st surface 75B is provided with a 1 st IC tag 73B-1. Therefore, the 1 st IC tag 73B-1 faces the front face portion 71B of the sleeve 70B. The 2 nd surface 76B of the blocking surface portion 74B faces the back surface portion 72B of the sleeve 70B. The 2 nd surface 76B is provided with a 2 nd IC tag 73B-2. Therefore, the 2 nd IC tag 73B-2 faces the back surface portion 72B of the sleeve 70B.

The 1 st IC tag 73B-1 stores the tag ID of the 1 st IC tag 73B-1, and the 2 nd IC tag 73B-2 stores the tag ID of the 2 nd IC tag 73B-2. Since the 1 st IC tag 73B-1 and the 2 nd IC tag 73B-2 are independent IC tags, their tag IDs are different from each other.

The blocking surface 74B is formed of a material (e.g., a magnetic material) that blocks transmission and reception of signals between the 1 st IC tag 73B-1 and the 2 nd IC tag 73B-2 and the reader 20. Therefore, the blocking surface 74B blocks the signal transmitted from the 2 nd surface 76B (back surface 72B) from being received by the 1 st IC tag 73B-1, and the signal from the 1 st IC tag 73B-1 is transmitted to the 2 nd surface 76B (back surface 72B). Similarly, the blocking surface 74B blocks the signal transmitted from the 1 st surface 75B (front surface 71B) from being received by the 2 nd IC tag 73B-2, and the signal from the 2 nd IC tag 73B-2 is transmitted to the 1 st surface 75B (front surface 71B).

The card 60 is accommodated in a space between the front face portion 71B and the blocking face portion 74B of the sleeve 70B. Hereinafter, for the sake of convenience, the card 60 stored in the sleeve 70B is referred to as "card 60 SB" for the sake of distinction from the card 60 alone. In other words, the card 60 and the sleeve 70B when the card 60 is housed in the sleeve 70B are regarded as one object and are described as [ card 60SB ].

When the card 60SB is placed in the partition Z so as to face upward, the card 60SB is placed so that the back surface portion 72B of the card 60SB contacts the playard F. In this case, the blocking surface 74B (magnetic material or the like) blocks transmission and reception of signals between the reader 20 disposed below the partition Z and the 1 st IC tag 73B-1, and therefore the reader 20 cannot read information (tag ID or the like) stored in the 1 st IC tag 73B-1. As a result, the reader 20 reads information only from the 2 nd IC tag 73B-2.

On the other hand, when the card 60SB is placed in the partition Z with the back surface facing upward, the card 60SB is placed so that the front surface portion 71B of the card 60SB contacts the game field F. In this case, the transmission and reception of signals between the reader 20 disposed below the zone Z and the 2 nd IC tag 73B-2 is blocked by the blocking surface 74B (magnetic material or the like), and therefore the reader 20 cannot read the tag ID stored in the 2 nd IC tag 73B-2. As a result, the reader 20 reads information (such as a tag ID) from only the 1 st IC tag 73B-1.

In this way, in the case where the card 60SB is placed in a right-side up manner, information is read only from the 2 nd IC tag 73B-2 by the reading device 20. Likewise, in the case where the card 60SB is placed with the back side facing upward, information is read only from the 1 st IC tag 73B-1 by the reading device 20. Therefore, the orientation of the front and back surfaces of the card 60SB can be determined based on the information stored in which of the 1 st IC tag 73B-1 and the 2 nd IC tag 73B-2 is read.

Processing the processing executed by the system 1B of embodiment 3 will be described below.

[ 3-2-1 ] FIG. 30 shows an example of the association processing of embodiment 3. In embodiment 3, the association processing shown in fig. 30 is executed instead of the association processing shown in fig. 10.

For example, the player places 1 card 60SB in his deck in a prescribed section Z (e.g., section Z11, etc.) in the casino F in a vertical and face-up manner. In this state, the association processing shown in fig. 30 is executed.

As shown in fig. 30, first, the control unit 41 of the information processing device 40 acquires a captured image of the imaging device 30 (S400B). Then, the control section 41 specifies the card ID of the card 60SB captured in the captured image from the captured image (S402B). Steps S400B, S402B are the same as steps S400, S402 of fig. 10.

Further, the control section 41 acquires the tag ID read by the reader 20 (S404B). In the case where the card 60SB is placed in a face-up manner, the tag ID stored in the 2 nd IC tag 73B-2 is read by the reading device 20, and the read tag ID is supplied to the information processing device 40. The control unit 41 acquires the tag ID thus supplied.

After step S404B is executed, control unit 41 outputs a front-back face reverse request notification indicating that the player is requested to reverse the front and back faces of card 60SB (S406B). For example, the control unit 41 displays an image indicating a front-back inversion request notification on the display unit 45. Alternatively, the control unit 41 causes the sound output unit 46 to output a sound indicating the front-back inversion request notification.

In response to the front-back reverse request notification, the player reverses the front and back of the card 60SB placed in the zone Z, and thereby turns the back of the card 60SB upward. The processing from step S408B onward is executed in this state.

That is, the control section 41 acquires the tag ID read by the reader 20 (S408B). In the case where the card 60SB is placed with the back side facing upward, the tag ID stored in the 1 st IC tag 73B-1 is read by the reading device 20, and the read tag ID is supplied to the information processing device 40. The control unit 41 acquires the tag ID thus supplied.

Then, the control section 41 registers the association between the card ID determined in step S402B and the tag ID acquired in steps S404B and S408B in the associated data D1B (S410B).

Fig. 31 shows an example of the related data D1B. As shown in fig. 31, the associated data D1B includes [ card ID ] and [ tag ID ] fields. The [ card ID ] field is the same as the [ card ID ] field of the related data D1 in embodiment 1. The [ tag ID ] field contains [ face up ] and [ back up ] fields as subfields. The [ face-up ] field is a field for registering the tag ID (i.e., the tag ID of the 2 nd IC tag 73B-2) acquired in a case where the card 60SB is placed in a face-up manner. The [ back-side-up ] field is a field for registering the tag ID (i.e., the tag ID of the 1 st IC tag 73B-1) acquired in a case where the card 60SB is placed in a back-side-up manner.

In step S410B, the control unit 41 adds a new record to the related data D1B, registers the card ID determined in step S402B in the [ card ID ] field, registers the tag ID acquired in step S404B in the [ face up ] field, and registers the tag ID acquired in step S408B in the [ back face up ] field.

After step S410B is executed, a completion notification indicating that the association process is completed is output, and the player removes the card 60SB placed in the section Z and places the next card 60SB in the section Z from the own card set so as to face vertically and frontally upward. In this state, the association processing shown in fig. 30 is executed again.

By executing the association processing shown in fig. 30, the information on all the cards 60SB included in the card set of the 1 st player is registered in the association data D1B with respect to the cards 60SB included in the card set of the 1 st player. By executing the association processing shown in fig. 30, the information on all the cards 60SB included in the deck group of the 2 nd player is registered in the association data D1B, as well as on the cards 60SB included in the deck group of the 2 nd player.

[ 3-2-2 ] FIG. 32 shows another example of the association processing according to embodiment 3. Instead of the association processing shown in fig. 30, the association processing shown in fig. 32 may be performed.

In addition, the association processing shown in FIG. 32 is premised on an IC tag writer for writing information to the 1 st IC tag 73B-1 and the 2 nd IC tag 73B-2 being provided below the above-described partition Z. Hereinafter, a case will be described where the reader 20 is an IC tag reader/writer having both functions of an IC tag reader and an IC tag writer.

As shown in fig. 32, first, the control unit 41 acquires a captured image of the imaging device 30 (S420B). Then, the control section 41 specifies the card ID of the card 60SB captured in the captured image from the captured image (S422B). The processing of steps S420B, S422B is the same as steps S400, S402 of fig. 10.

After executing step S422B, the control section 41 writes the card ID and the front-back surface label determined in step S422B in the 2 nd IC tag 73B-2 of the card 60SB placed in the above-described partition Z (S424B).

The front-back mark is information indicating whether the card 60SB is placed in a front-side-up or back-side-up manner. For example, the value [0] or [1] is set as the obverse-reverse flag. The value [0] indicates that the card 60SB is placed face-up, and the value [1] indicates that the card 60SB is placed face-up. In step S424B, a value [0] indicating that it is front-side up is written as a front-back mark.

The control section 41 transmits the card ID determined in step S422B and a write instruction of the front-back face mark (0) to the reading device 20(IC tag reader/writer) disposed below the above-described partition Z. Then, in accordance with the write instruction, the reader 20 writes the card ID and the front-back surface mark (0) to the 2 nd IC tag 73B-2 of the card 60SB placed in the zone Z. In this case, since the transmission and reception of signals between the 1 st IC tag 73B-1 and the reader 20 are blocked by the blocking surface 74B (magnetic material or the like), writing to the 1 st IC tag 73B-1 is not performed at this point in time.

After step S424B is executed, control unit 41 outputs a front-back flip request notification indicating that the player is requested to flip front-back of card 60SB (S426B). The process of step S426B is the same as step S406B of fig. 30.

In response to the front-back reverse request notification, the player reverses the front and back of the card 60SB placed in the zone Z, and thereby turns the back of the card 60SB upward. The process of step S428B is executed in this state.

That is, the control unit 41 writes the card ID and the front-back surface flag determined in step S422B to the 1 st IC tag 73B-1 of the card 60SB placed in the aforementioned zone Z (S428B). In this case, a value [1] indicating that the back surface is upward is written as the front-back surface mark.

Specifically, the control section 41 transmits the card ID and the write instruction of the front-back surface mark (1) determined in step S422B to the reading device 20(IC tag reader/writer) placed below the partition Z. Then, in accordance with the write instruction, the reader 20 writes the card ID and the front-back surface mark (1) to the 1 st IC tag 73B-1 of the card 60SB placed in the zone Z. In this case, since the transmission and reception of signals between the 2 nd IC tag 73B-2 and the reader 20 are blocked by the blocking surface 74B (magnetic material or the like), writing to the 2 nd IC tag 73B-2 is not performed at this point in time.

After step S428B is executed, a completion notification indicating that the association processing is completed is output, and the 1 st player takes the card 60SB placed in the aforementioned division Z and places the next card 60SB in the aforementioned division Z from the own deck in a vertically and right-side-up manner. In this state, the association processing shown in fig. 32 is executed again.

By executing the association processing shown in fig. 32, each card 60SB included in the deck group of the 1 st player stores the card ID and the front-back face mark in the 1 st IC tag 73B-1 and the 2 nd IC tag 73B-2 of each card 60SB included in the deck group of the 1 st player. Further, by executing the association processing shown in fig. 32 for each card 60SB included in the deck group of the 2 nd player, the card ID and the front-back face mark are also stored in the 1 st IC tag 73B-1 and the 2 nd IC tag 73B-2 of each card 60SB included in the deck group of the 2 nd player.

3-2-3 in embodiment 3, determination processing similar to that shown in fig. 13 is also executed. Here, the determination processing of embodiment 3 will be described with reference to fig. 13. Here, the description is made on the premise that the related data D1B shown in fig. 31 is stored in the storage unit 42.

In embodiment 3, in step S432, the control unit 41 specifies the position and the vertical and horizontal orientations of the card 60SB placed on the game field F, and does not specify the front and rear orientations of the card 60 SB. At this time, the determination result in step S432 is registered in the 1 st determination result data D2B.

Fig. 33 shows an example of the 1 st determination result data D2B. As shown in fig. 33, the 1 st determination result data D2B contains [ area ID ] and [ cross tag ] fields. The [ area ID ] and [ vertical and horizontal flag ] fields are the same as those of the [ area ID ] and [ vertical and horizontal flag ] field of the 1 st determination result data D2 of embodiment 1.

In embodiment 3, in step S436, the control unit 41 specifies the card ID, the position, and the front-back direction of the card 60SB placed on the game field F.

For example, in the case where the card 60SB is placed in the partition Z10 in a face-up manner, the tag ID stored in the 2 nd IC tag 73B-2 is read by the reading device 20-10 and supplied to the information processing device 40 as the read result data of the reading device 20-10. In this case, the transmission and reception of signals between the 1 st IC tag 73B-1 and the reader 20-10 is blocked by the blocking surface 74B, and therefore the tag ID stored in the 1 st IC tag 73B-1 is not read by the reader 20-10.

The control section 41 determines the card ID and the front-back surface orientation of the card 60SB based on the tag ID read by the reading device 20-10. The method of determining the card ID is basically the same as step S436 of embodiment 1, except that the related data D1B is referred to instead of the related data D1.

The control unit 41 refers to the related data D1B and determines which of the fields [ face-up ] and [ back-up ] the tag ID read by the reading device 20-10 is registered. Then, in a case where the tag ID read by the reading device 20-10 is registered in the [ face-up ] field, the control section 41 determines that the card 60SB is face-up. On the other hand, in the case where the tag ID read by the reading device 20-10 is registered in the [ back-side-up ] field, the control section 41 determines that the card 60SB is back-side-up.

At this time, the determination result in step S426 is registered in the 2 nd determination result data D3B. Fig. 34 shows an example of the 2 nd determination result data D3B. As shown in fig. 34, the 2 nd determination result data D3B includes [ reading device ID ], [ card ID ], and [ front-back label ] fields. The [ reader ID ] and [ card ID ] fields are the same as those of the [ reader ID ] and [ card ID ] fields of the 2 nd determination result data D3 of embodiment 1, and the [ front and back side mark ] field is the same as that of the 1 st determination result data D2 of embodiment 1.

For example, when the tag ID is read by the reader 20-10, the control unit 41 registers the card ID and the front-back direction specified by the tag ID in the [ card ID ] and [ front-back face mark ] fields of the record of the reader ID [ R10 ].

In addition, although the above description has been made on the premise that the related data D1B shown in fig. 31 is stored in the storage unit 42 by the association processing shown in fig. 30, in the case where the card ID and the front-back surface mark are stored in the 1 st IC tag 73B-1 and the 2 nd IC tag 73B-2 of the card 60SB by the association processing shown in fig. 32, the card ID and the front-back surface mark are read by the reading device 20-10, and therefore, in step S436, the control unit 41 registers the card ID and the front-back surface mark read by the reading device 20-10 in the [ card ID ] and [ front-back surface mark ] fields of the record of the reading device ID [ R10 ].

In addition, in embodiment 3, in step S438, the control unit 41 generates the field situation data D4 from the 1 st and 2 nd determination result data D2B and D3B. The playground situation data D4 is the same as in embodiment 1. The processing of step S438 in this case is the same as step S438 of embodiment 1, except that the front and back surface markers registered in the [ front and back surface markers ] field of the 2 nd determination result data D3B are registered in the [ front and back surface markers ] field of the field situation data D4.

In the situation shown in fig. 7, the card set 600-1 (i.e., the plurality of cards 60SB stacked with the back surfaces facing upward) is placed in the partition Z7, but in embodiment 3, since the blocking surface portion 74B is present, only the ID tag in the 1 st IC tag 73B-1 of the lowermost card 60SB stored in the card set 600-1 is read. As a result, in the [ card ID ] field of the record of the reading device ID [ R7] of the 2 nd determination result data D3B and the record of the division ID [ Z7] of the playground situation data D4, only the card ID of the lowermost card 60SB in the card set 600-1 placed in the division Z7 is registered. The same applies to the partitions Z1, Z15 and Z21.

[ 3-2-4 ] in embodiment 3, the display control processing shown in FIG. 18 and the processing shown in FIG. 19 are also executed. However, in the parts PA-1 to PA-4 of the game field image G of embodiment 3, the numerical value indicating the number of cards 60SB included in the card sets 600-1 to 600-4 is not displayed.

Effect 3-3 according to embodiment 3, the orientation of the front and back surfaces of the card 60SB placed on the playard F can be determined based on the reading result of the reading device 20.

In addition, in embodiment 3, in the case where the card 60SB is placed in a face-up manner, it is necessary to ensure that the information stored in the 1 st IC tag 73B-1 is not read by the reading device 20, and in the case where the card 60SB is placed in a back-up manner, it is necessary to ensure that the information stored in the 2 nd IC tag 73B-2 is not read by the reading device 20.

For example, if the distance between the 1 st IC tag 73B-1 and the reading device 20 becomes large in the case where the card 60SB is placed in a face-up manner (i.e., becomes large to the extent that the information stored in the 1 st IC tag 73B-1 cannot be read by the reading device 20), and the distance between the 2 nd IC tag 73B-2 and the reading device 20 becomes large in the case where the card 60SB is placed in a back-up manner (i.e., becomes large to the extent that the information stored in the 2 nd IC tag 73B-2 cannot be read by the reading device 20), it is not necessary to take measures for the above-described assurance in particular. However, since the card 60 and the sleeve 70 are thin, the distance does not increase, and therefore, measures for ensuring the above need to be taken. In this regard, in embodiment 3, the above-described assurance is achieved by providing the blocking surface portion 74B in the sleeve 70B.

Modifications of embodiment 3 will be described below in 3-4 modifications.

[ 3-4-1 ] in the above-described embodiment, the 2 nd IC tag 73B-2 is provided on the 2 nd surface 76B of the blocking surface portion 74B, but the 2 nd IC tag 73B-2 may be provided on the inner surface of the back surface portion 72B of the sleeve 70B.

[ 3-4-2 ] in the above-described embodiment, the blocking surface portion 74B is fixed to the sleeve 70B, but the blocking surface portion 74B may be a sheet-like object that is housed in the sleeve 70B together with the card 60, such as the object 80 shown in fig. 20.

[ 3-4-3 ] in the above-described embodiment, the blocking surface portion 74B is formed of a magnetic material, but the blocking surface portion 74B may be formed of a material other than a magnetic material. The blocking surface portion 74B may be made of any material as long as it can block transmission and reception of signals between the 1 st IC tag 73B-1 and the reader 20 via the back surface portion 72B of the sleeve 70B or transmission and reception of signals between the 2 nd IC tag 73B-2 and the reader 20 via the front surface portion 71A of the sleeve 70B.

In embodiment 3, the control unit 41 may determine the orientation of the front and back surfaces of the card 60SB in step S422. That is, the control section 41 may determine the front-back surface orientation of the card 60SB from the captured image of the imaging device 30 and also determine the front-back surface orientation of the card 60SB from the reading result of the reading device 20. In this case, the accuracy of the determination result of the front-back surface orientation can also be improved by comparing the determination result of the front-back surface orientation obtained from the captured image of the imaging device 30 with the determination result of the front-back surface orientation obtained from the reading result of the reading device 20.

Fig. 35 is a functional block diagram for explaining functional elements included in the system 1B according to embodiment 3. In fig. 35, the same functional elements as those of embodiment 1 (the image pickup unit 110, the captured image acquisition unit 120, the reading unit 130, the reading result acquisition unit 140, the display control unit 160, and the display unit 170) are denoted by the same reference numerals as those of fig. 22, and the description of these functional elements will be omitted here, and the subject 100B and the specification unit 150B will be described. Note that description of the words and phrases is omitted for the points overlapping with embodiment 1.

[ 3-5-1 ] first, the object 100B will be described. Here, differences between the object 100B and the object 100 in embodiment 1 will be described.

The object 100B includes a 1 st face and a 2 nd face. These 1 st and 2 nd faces are the same as the 1 st and 2 nd faces described as being included in the object 100 of embodiment 1.

The object 100B includes a 1 st holding portion 101B and a 2 nd holding portion 102B. The 1 st holding unit 101B and the 2 nd holding unit 102B hold identification information for identifying the type and state of the object 100B placed on the object surface. The specifying information in this case includes information as a basis for specifying the type of the object 100B and information as a basis for specifying the state of the object 100B. When the object 100B is an object in which a game medium is stored in a storage, information as a basis for specifying the type or state of a game medium placed on the object surface in a state of being stored in the storage corresponds to [ information as a basis for specifying the type or state of the object 100B ].

The information held by the 1 st holding unit 101B and the 2 nd holding unit 102B is read by the reading unit 130. In order to distinguish which of the 1 st holding unit 101B and the 2 nd holding unit 102B the information read by the reading unit 130 is held, different information is included in the information held in each of the 1 st holding unit 101B and the 2 nd holding unit 102B. For example, the identification information of the 1 st holding unit 101B is held in the 1 st holding unit 101B, and the identification information of the 2 nd holding unit 102B is held in the 2 nd holding unit 102B. In embodiment 3, the front-back direction of the object 100B is specified based on the different information held in each of the 1 st holding unit 101B and the 2 nd holding unit 102B, and therefore the different information corresponds to [ information that is a basis for specifying the state of the object 100B ].

The object 100B includes a restriction unit 103B. The restricting unit 103B restricts the reading of the information held in the 1 st holding unit 101B by the reading unit 130 via the 2 nd face of the object 100B, and restricts the reading of the information held in the 2 nd holding unit 102B by the reading unit 130 via the 1 st face of the object 100B.

For example, the 1 st holding unit 101B is a 1 st IC tag provided to communicate with the reading unit 130(IC tag reader) via the 1 st face of the object 100B. In other words, the 1 st holding portion 101B is a 1 st IC tag restricted from communicating with the reading portion 130(IC tag reader) via the 2 nd face portion of the object 100B.

The 2 nd holding unit 102B is a 2 nd IC tag provided to communicate with the reading unit 130(IC tag reader) via the 2 nd face of the object 100B. In other words, the 2 nd holding portion 102B is a 2 nd IC tag restricted from communicating with the reading portion 130(IC tag reader) via the 1 st face portion of the object 100B.

The 1 st IC tag is provided so as to face the 1 st face of the object 100B. Alternatively, the 1 st IC tag is provided on the inner surface of the 1 st face of the object 100B. The 1 st IC tag is provided on the 1 st face side of the object 100B than the 2 nd IC tag. The 2 nd IC tag is provided so as to face the 2 nd face of the object 100B. Alternatively, the 2 nd IC tag is provided on the inner surface of the 2 nd face of the object 100B. The 2 nd IC tag is provided on the 2 nd face side of the object 100B than the 1 st IC tag.

The 1 st IC tag is disposed between the 1 st face portion of the object 100B and the regulating portion 103B, and the 2 nd IC tag is disposed between the 2 nd face portion of the object 100B and the regulating portion 103B. The restricting unit 103B restricts communication between the 1 st IC tag and the reading device 20 for reading information held in the 1 st IC tag or the 2 nd IC tag via the 2 nd face of the object 100B, and restricts communication between the reading device 20 and the 2 nd IC tag via the 1 st face of the object 100B.

For example, the restricting portion 103B includes a magnetic body provided between the 1 st IC tag and the 2 nd surface portion of the object 100B. The restricting portion 103B includes a magnetic material provided between the 2 nd IC tag and the 1 st surface portion of the object 100B. In other words, the restricting portion 103B includes a magnetic body provided between the 1 st IC tag and the 2 nd IC tag. Any member that can block the signal (radio wave) transmitted from the 1IC tag via the 2 nd surface of the object 100B or the signal (radio wave) transmitted from the 2 nd IC tag via the 1 st surface of the object 100B may be used as the limiting unit 103B.

[ 3-5-2 ] the determination section 150B will be explained. The determination section 150B includes a 1 st determination section 151B and a 2 nd determination section 152B.

The 1 st specifying unit 151B specifies the position and orientation of the object 100B based on the captured image of the imaging device 30. For example, the 1 st specifying unit 151B specifies the position and the vertical and horizontal directions of the object 100B, as in the 1 st specifying unit 151 of embodiment 1.

The 2 nd specifying unit 152B specifies the position, the type, and the orientation of the object 100B based on the reading result of the reading device 20. The 2 nd specifying unit 152B specifies the position and the type of the object 100B in the same manner as the 2 nd specifying unit 152 of the 1 st embodiment.

The 2 nd specifying unit 152B also specifies the orientation of the front and back surfaces of the object 100B. That is, the 2 nd specifying unit 152B specifies on the basis of the reading result of the reading device 20 on the information stored in the 1 st holding unit 101B (1 st IC tag) or the 2 nd holding unit 102B (2 nd IC tag), which of the 1 st face and the 2 nd face of the object 100B is placed on the object surface so as to face the object surface.

For example, when the reading unit 130 reads the information stored in the 1 st holding unit 101B (1 st IC tag), the 2 nd specifying unit 152B determines that the 1 st face of the object 100B faces the reading unit 130. For example, if the reading unit 130 is disposed below the target surface, the 2 nd specifying unit 152B determines that the 1 st face of the target object 100B is facing the target surface. In addition, if the reading unit 130 is disposed above the target surface, the 2 nd specification unit 152B determines that the 2 nd face of the target object 100B is facing the target surface.

On the other hand, when the information stored in the 2 nd holding unit 102B (2 nd IC tag) is read by the reading unit 130, the 2 nd specifying unit 152B determines that the 2 nd face of the object 100B faces the reading unit 130. For example, if the reading unit 130 is disposed below the target surface, the 2 nd specifying unit 152B determines that the 2 nd face of the target object 100B is facing the target surface. In addition, if the reading unit 130 is disposed above the target surface, the 2 nd specifying unit 152B determines that the 1 st face of the target object 100B is facing the target surface.

[ 3-5-3 ] in the case of the above-described example of the card game, the card 60SB corresponds to an example of the object 100B. The front portion 71B and the back portion 72B of the sleeve 70B correspond to examples of the [ 1 st portion ] and the [ 2 nd portion ], respectively. The 1 st IC tag 73B-1 and the 2 nd IC tag 73A-2 of the sleeve 70B correspond to examples of the 1 st holding portion 101B (1 st IC tag) and the 2 nd holding portion 102B (2 nd IC tag), respectively. The blocking surface portion 74B of the sleeve 70B corresponds to an example of the restricting portion 103B.

For example, when the information stored in the 1 st IC tag 73B-1 of the card 60SB is read by the reading device 20, the 2 nd specifying unit 152B specifies that the card 60SB is placed with the back surface facing upward. On the other hand, when the information stored in the 2 nd IC tag 73B-2 of the card 60SB is read by the reading device 20, the 2 nd specifying unit 152B specifies that the card 60SB is placed with the front side facing upward.

[4 ] embodiment 4 of the present invention will be explained.

The embodiment 4 is different from the embodiment 1 in that the type or state of the card is determined by reading the code printed on the sleeve with invisible ink. The following description deals with differences from embodiment 1. In the following description, the same elements as those of embodiment 1 are denoted by the same reference numerals, and description thereof is omitted.

[ 4-1. overview ] fig. 36 shows the configuration of a system 1C according to embodiment 4. As shown in FIG. 36, the system 1C includes a game board 10C, a 1 st camera 30C-1, a 2 nd camera 30C-2, an information processing device 40, and a display terminal device 50. The information processing apparatus 40 and the display terminal apparatus 50 are the same as those of embodiment 1.

The game board 10C is basically the same as the game board 10 of embodiment 1, except that it does not include the reading device 20(IC tag reader).

The 1 st imaging device 30C-1 corresponds to the imaging device 30 of embodiment 1 and is a visible light camera. On the other hand, the 2 nd imaging device 30C-2 is an invisible light camera (e.g., an infrared camera or the like). The 2 nd camera 30C-2 is used to read a code printed in invisible ink. The invisible ink refers to an ink (e.g., infrared ink) that can be recognized by an image sensor by irradiation of invisible light (e.g., infrared light or the like).

Fig. 37 is a diagram for explaining an example of a sleeve 70C according to embodiment 4. As with the sleeve 70 of embodiment 1, the front face portion 71C of the sleeve 70C is transparent, and the front face 61 of the card 60 housed in the sleeve 70C can be visually recognized from the outside of the sleeve 70C. In addition, the back surface portion 72C of the sleeve 70C is opaque, as in the sleeve 70 of embodiment 1, and the appearance of the back surface portion 72C seen by the eyes is the same for all the sleeves 70C.

The front face 71C of the sleeve 70C includes the 1 st code 77C-1. The 1 st code 77C-1 is printed on the outer side surface of the front face portion 71C using invisible ink. In fig. 37, the 1 st code 77C-1 is printed in the center of the front face portion 71C, but the 1 st code 77C-1 may be printed in a position other than the center. The 1 st code 77C-1 is a code in which the sleeve ID of the sleeve 70C is embedded. That is, the 1 st code 77C-1 is a code obtained by encoding the sleeve ID of the sleeve 70C in accordance with a predetermined specification (rule). In other words, the 1 st code 77C-1 is a code including a pattern generated based on the sleeve ID of the sleeve 70C (a pattern unique to the sleeve ID). The 1 st code 77C-1 is, for example, a two-dimensional code (QR code (registered trademark) or the like). In addition, the sleeve ID is information that uniquely identifies each sleeve 70C.

Additionally, the back portion 72C of the sleeve 70C includes the 2 nd code 77C-2. The 2 nd code 77C-2 is printed on the outer side surface of the back surface portion 72C using invisible ink. The 2 nd code 77C-2 is a code in which the sleeve ID of the sleeve 70C is embedded, similarly to the 1 st code 77C-1. That is, the sleeve ID of the sleeve 70C is embedded in both the 1 st code 77C-1 and the 2 nd code 77C-2.

Hereinafter, the 1 st code 77C-1 and the 2 nd code 77C-2 may be collectively referred to as "code 77C". Hereinafter, the card 60 housed in the sleeve 70C will be referred to as "card 60 SC" for convenience, in order to distinguish it from the card 60 alone. In other words, the card 60 and the sleeve 70C when the card 60 is housed in the sleeve 70C are regarded as one object and are described as [ card 60SC ].

The 2 nd camera 30C-2 is also fixed above the game field F, as is the 1 st camera 30C-1. The 2 nd camera 30C-2 also captures an image including at least the divisions Z1 through Z30 of the field F.

For example, the 2 nd camera 30C-2 includes a light source for irradiating the game field F with invisible light and an image sensor for capturing images of reflected light reflected by the game field F or a card 60SC placed on the game field F, converting the captured images into an electronic image signal, and outputting the electronic image signal. Further, the reflected light from which the visible light (disturbance light) is removed is input to the image sensor. The 2 nd camera 30C-2 is used to read the 1 st code 77C-1 or the 2 nd code 77C-2 of the card 60SC placed at the game field F.

The 2 nd camera 30C-2 and the information processing apparatus 40 are connected via a cable conforming to a prescribed interface standard. Alternatively, the 2 nd photographing device 30C-2 and the information processing device 40 can communicate via a communication network. The 2 nd imaging device 30C-2 images the game field F at predetermined intervals, and the captured images are supplied to the information processing device 40 via the cable or the communication network.

When the card 60SC is placed on the game field F with the front side facing upward, the 1 st code 77C-1 of the front face portion 71C of the card 60SC is included in the captured image of the 2 nd imaging device 30C-2, and information (sleeve ID) embedded in the 1 st code 77C-1 is acquired based on the captured image. On the other hand, when the card 60SC is placed on the game field F with the back surface facing upward, the 2 nd code 77C-2 of the back surface portion 72C of the card 60SC is included in the captured image of the 2 nd imaging device 30C-2, and information (sleeve ID) embedded in the 2 nd code 77C-2 is acquired based on the captured image.

[ 4-2 ] Process the process performed by the system 1C of embodiment 4 will be described.

[ 4-2-1 ] FIG. 38 shows an example of the association processing according to embodiment 4. For example, the player places 1 card 60SC in his own card set in a prescribed division Z (e.g., division Z11, etc.) in the playing field F in a vertically and face-up manner. In this state, the association processing shown in fig. 38 is executed.

As shown in fig. 38, first, the control unit 41 of the information processing device 40 acquires the captured image of the 1 st imaging device 30C-1 (S400C). Then, the control section 41 specifies the card ID of the card 60SC captured in the captured image from the captured image (S402C). Steps S400C, S402C are the same as steps S400, S402 of fig. 10.

Then, the control unit 41 acquires the captured image of the 2 nd imaging device 30C-2 (S404C). Then, the control unit 41 acquires the sleeve ID from the 1 st code 72C-1 captured in the captured image (S406C). Then, the control unit 41 registers the association between the card ID determined in step S402C and the sleeve ID acquired in step S406C in the associated data D1C (S408C).

Fig. 39 shows an example of related data D1C according to embodiment 4. As shown in fig. 39, the associated data D1C contains [ card ID ] and [ sleeve ID ] fields. The [ card ID ] field is the same as the [ card ID ] field of the related data D1 of embodiment 1. The [ sleeve ID ] field is a field for registering a sleeve ID.

In step S408C, the control unit 41 adds a new record to the associated data D1C, and registers the card ID determined in step S402C and the sleeve ID acquired in step S406C in the [ card ID ] and [ sleeve ID ] fields of the record.

After step S408C is executed, a completion notification indicating that the association processing is completed is output, and the player takes the card 60SC placed in the aforementioned sub-zone Z and places the next card 60SC in the aforementioned sub-zone Z from his own card set in a vertically and right-side-up manner. In this state, the association processing shown in fig. 38 is executed again.

By executing the association processing shown in fig. 38 with respect to each card 60SC included in the card set of the 1 st player, the information of all the cards 60SC included in the card set of the 1 st player is registered in the association data D1C. Further, by executing the association processing shown in fig. 38, the information on all the cards 60SC included in the deck group of the 2 nd player is also registered in the association data D1C.

[ 4-2-2 ] FIG. 40 shows an example of the determination processing of embodiment 4. As shown in fig. 40, first, the control unit 41 of the information processing device 40 acquires the captured image of the 1 st imaging device 30C-1 (S430C). Then, the control section 41 determines the position and orientation of the card 60SC from the captured image (S432C). The processing of steps S430C, S432C is the same as steps S430, S432 of fig. 13. The determination result in step S432C is registered in the 1 st determination result data D2. The 1 st determination result data D2 is the same as in the 1 st embodiment.

After executing step S432C, the control unit 41 acquires the captured image of the 2 nd camera 30C-2 (S434C), and the control unit 41 specifies the position of the card 60SC and the card ID from the captured image (S436C).

For example, the control unit 41 determines whether or not the code 77C (1 st code 77C-1 or 2 nd code 77C-2) is captured in each of the areas A1 to A30 of the captured image. Further, the control section 41 acquires the sleeve ID from the captured code 77C.

The determination result in the step S436C is registered in the 2 nd determination result data D3C. Fig. 41 shows an example of the 2 nd determination result data D3C. As shown in fig. 41, the 2 nd determination result data D3C contains [ area ID ] and [ card ID ] fields. The [ area ID ] field is the same as the [ area ID ] field of the 1 st determination result data D2 of embodiment 1, and the [ card ID ] field is the same as the [ card ID ] field of the 2 nd determination result data D3 of embodiment 1.

For example, when the code 77C is imaged in the area a10, the control unit 41 registers the sleeve ID acquired from the code 77C in the [ card ID ] field of the record of the area ID [ a10 ].

After executing step S436C, the control section 41 generates the casino condition data D4 based on the 1 st determination result data D2 and the 2 nd determination result data D3C (S438C). The playground situation data D4 is the same as in embodiment 1.

In the situation shown in fig. 7, the card set 600-1 (i.e., the plurality of cards 60SC stacked with the back surfaces facing upward) is placed in the partition Z7, but in embodiment 4, only the 2 nd code 77C-2 of the uppermost card 60SC in the card set 600-1 placed in the partition Z7 is captured in the captured image of the 2 nd imaging device 30C-2. Therefore, in the [ card ID ] field of the record of the area ID [ a7] of the 2 nd determination result data D3C, the record of the division ID [ Z7] of the playground situation data D4, only the card ID of the uppermost card 60SC in the card set 600-1 placed in the division Z7 is registered. The same applies to the partitions Z1, Z15 and Z21.

[ 4-2-3 ] in embodiment 4, the display control process shown in FIG. 18 and the process shown in FIG. 19 are also executed. However, in the parts PA-1 to PA-4 of the game field image G of embodiment 4, the numerical value indicating the number of cards 60SC included in the card sets 600-1 to 600-4 is not displayed.

Effect of [ 4-3 ] according to the 4 th embodiment, in the case where the card 60SC is placed on the field F with the front face facing upward, the 1 st code 77C-1 of the front face portion 71C of the card 60SC is photographed by the 2 nd photographing device 30C-2, whereby the information embedded in the 1 st code 77C-1 can be read, and as a result, the card ID of the card 60SC can be acquired. On the other hand, when the card 60SC is placed on the game field F with the back surface facing upward, the 2 nd code 77C-2 of the back surface portion 72C of the card 60SC is captured by the 2 nd imaging device 30C-2, and the information embedded in the 2 nd code 77C-2 can be read, and as a result, the card ID of the card 60SC can be acquired. In this way, according to embodiment 4, the card ID of the card 60SC can be acquired regardless of whether the card 60SC is placed with the front side facing upward or the back side facing upward.

According to embodiment 4, even when the card 60SC is placed on the game field F with the back surface facing upward (that is, when the card 60SC is placed on the game field F with the front surface 61 invisible), the information (the name, performance, and the like of the card 60) described on the front surface 61 of the card 60 can be specified based on the information in the 2 nd code 77C-2 held in the back surface portion 72C of the card 60 SC.

Further, according to embodiment 4, since the code 77C is printed on the sleeve 70C, even when the card 60 itself is not printed with the code 77C, the type and state of the card 60 can be specified based on the captured image of the 2 nd imaging device 30C-2 by storing and using the card 60 in the sleeve 70C. That is, since the code 77C does not need to be printed on the card 60 itself, for example, an existing card 60 on which the code 77C is not printed can be used.

Further, according to embodiment 4, since the code 77C is printed in an invisible state that cannot be recognized by a person, it is possible to prevent the appearance of the card 60SC (card 60) from being damaged when viewed from a person. In addition, even when the card 60SC is placed on the game field F with the back surface facing upward, the opponent can grasp the name, performance, and the like of the card 60 that cannot be grasped originally without relying on the 2 nd code 77C-2 printed on the back surface portion 72C.

[ 4-4 ] modifications of embodiment 4 will be described.

[ 4-4-1 ] for example, information indicating the code printed on the front face portion 71C may be embedded in the 1 st code 77C-1 together with the sleeve ID. Further, the 2 nd code 77C-2 may be embedded with information indicating a code printed on the back surface portion 72C together with the sleeve ID.

Specifically, [0] indicating the front surface may be embedded in the 1 st code 77C-1 together with the sleeve ID as the front-back surface mark, and [1] indicating the back surface may be embedded in the 2 nd code 77C-2 together with the sleeve ID as the front-back surface mark. Further, the sleeve ID and the front-back mark may be acquired from the code 77C captured in the captured image of the 2 nd imaging device 30C-2.

In this way, in the case where the card 60SC is placed in the face-up manner, by acquiring [0] from the 1 st code 77C-1 as the face-back mark, it can be determined that the card 60SC is placed in the face-up manner, and in the case where the card 60SC is placed in the back-up manner, by acquiring [1] from the 2 nd code 77C-2 as the face-back mark, it can be determined that the card 60SC is placed in the back-up manner. That is, the orientation of the front and back surfaces of the card 60SC can be determined based on the captured image of the 2 nd camera 30C-2. That is, the state of the card 60SC can be determined based on the captured image of the 2 nd camera 30C-2.

[ 4-4-2 ] for example, a plurality of codes 77C having a predetermined positional relationship may be printed on the back surface portion 72C in the same manner as the 1 st IC tag 73-1 and the 2 nd IC tag 73C-2 according to embodiment 2. Further, when the card 60SC is placed with the back surface facing upward, the vertical and horizontal orientations of the card 60SC may be determined based on the positional relationship of the plurality of codes 77C captured in the captured image of the 2 nd imaging device 30C-2.

Further, a plurality of codes 77C having a predetermined positional relationship may also be printed on the front face portion 71C. Further, when the card 60SC is placed so as to face upward, the vertical and horizontal orientations of the card 60SC may be determined based on the positional relationship of the plurality of codes 77C captured in the captured image of the 2 nd imaging device 30C-2.

In this way, the longitudinal and lateral orientations of the card 60SC can be determined based on the captured image of the 2 nd camera 30C-2.

[ 4-4-3 ] alternatively, for example, the card ID of the card 60 may be embedded in the 1 st code 77C-1 and the 2 nd code 77C-2.

Fig. 42 is a functional block diagram for explaining functional elements included in the system 1C according to embodiment 4. In fig. 42, the same reference numerals as those in fig. 22 are assigned to the same functional elements (display control unit 160 and display unit 170) as those in embodiment 1, and the description of these functional elements is omitted here. Note that description of the words and phrases is omitted for the points overlapping with embodiment 1.

[ 4-5-1 ] first, the object 100C will be described. The object 100C is an object in which a game medium is accommodated in the accommodation body.

The game medium has a surface having an appearance corresponding to the kind of the game medium (hereinafter, referred to as a "feature surface" for convenience). For example, the feature surface is a surface having an appearance specific to the kind of game medium. For example, the feature plane is a plane on which text or a pattern corresponding to the type of the game medium is recorded.

The receiving body includes a 1 st face and a 2 nd face. These 1 st and 2 nd faces are the same as the 1 st and 2 nd faces described as being included in the storage body (object 100) in embodiment 1. In a state where the game medium is stored in the storage body, the 1 st face portion (inner face of the 1 st face portion) faces the characteristic face of the game medium. For example, the 1 st surface portion is formed entirely or partially of a transparent material (such as a transparent film), and the 1 st surface portion is configured to be able to visually recognize a characteristic surface of the game medium stored in the storage body from the outside of the storage body through the 1 st surface portion.

The object 100C includes a 1 st holding portion 101C and a 2 nd holding portion 102C. The 1 st holding portion 101C is provided on the 1 st surface of the housing. The 1 st holding unit 101C holds 1 st specifying information for specifying the type or state of the game medium stored in the storage body.

For example, the 1 st specifying information is recorded in an invisible state that is invisible to a person on the 1 st face of the object 100C (storage body). In this case, the portion in which the 1 st specifying information is recorded in an invisible state corresponds to the 1 st holding unit 101C. For example, the 1 st determination information is recorded on the 1 st face using invisible ink. For example, the 1 st identification information is written on the outer side surface of the 1 st face portion.

[ 1 st specifying information ] is information as a basis for specifying at least one of the type and the state of the game medium stored in the storage body. In other words, [ 1 st specifying information ] includes at least one of information as a basis for specifying the type of the game medium stored in the storage body and information as a basis for specifying the state of the game medium stored in the storage body.

For example, in a case where there is data associating a container ID that uniquely identifies a container with a game medium ID of a game medium stored in the container, and the type of game medium stored in the container can be specified based on the container ID, [ 1 st specifying information ] includes the container ID as [ information that is a basis for specifying the type of game medium stored in the container ]. In addition, for example, [ 1 st specifying information ] may include a game medium ID that uniquely identifies the kind of game medium.

For example, the [ 1 st specifying information ] may include 1 st identifying information for identifying the 1 st holding unit 101C as [ information for specifying the state of the game medium stored in the storage body ]. For example, when the 1 st identification information stored in the 1 st holding unit 101C of the 1 st face is read, it is determined that the object 100C is placed on the target surface so that the 2 nd face comes into contact with the target surface. Therefore, [ 1 st identification information ] may also include 1 st identification information identifying the 1 st holding part 101C as [ information as a basis for determining the arrangement form of the object 100C (whether the object 100C is placed on the object surface in such a manner that the 2 nd face is in contact with the object surface) ].

On the other hand, the 2 nd holding portion 102C is provided on the 2 nd surface portion of the housing. The 2 nd holding unit 102C holds the 2 nd specifying information for specifying the type or state of the game medium stored in the storage body.

For example, the 2 nd specifying information is written on the 2 nd face of the object 100C (storage body) in an invisible state where a person cannot visually recognize it. At this time, the portion in which the 2 nd specifying information is described in an invisible state corresponds to the 2 nd holding portion 102C. For example, the 2 nd determination information is described on the 2 nd face using invisible ink. For example, the 2 nd specifying information is written on the outer side surface of the 2 nd face portion.

Similarly to the 1 st specifying information, [ 2 nd specifying information ] is information as a basis for specifying at least one of the type and the state of the game medium stored in the storage body.

For example, [ 2 nd specifying information ] includes a container ID of the container or a game medium ID of a game medium stored in the container as [ information as a basis for specifying the type of game medium stored in the container ].

For example, the [ 2 nd identification information ] may include 2 nd identification information for identifying the 2 nd holding unit 102C as [ information for identifying a base of the state of the object 100C ]. For example, when the 2 nd identification information stored in the 2 nd holding unit 102C of the 2 nd face is read, it is determined that the object 100C is placed on the target surface so that the 1 st face comes into contact with the target surface. Therefore, [ 2 nd identification information ] may also include 2 nd identification information identifying the 2 nd holding part 102C as [ information as a basis for determining the arrangement form of the object 100C (whether the object 100C is placed on the object surface in such a manner that the 1 st face is in contact with the object surface) ].

In addition, in the case where the 1 st identification information and the 2 nd identification information each include only [ information as a basis for identifying the type of game medium stored in the storage body ], the 1 st identification information and the 2 nd identification information are the same information.

The 1 st surface and the 2 nd surface of the container have the following positional relationship: when the object 100C is placed on the target surface so that the outer side surface of the 1 st face portion is in contact with the target surface, the 2 nd identification information held in the 2 nd holding portion 102C of the 2 nd face portion can be read by the reading portion 130C, and when the object 100C is placed on the target surface so that the outer side surface of the 2 nd face portion is in contact with the target surface, the 1 st identification information held in the 1 st holding portion 101C of the 1 st face portion can be read by the reading portion 130C.

For example, the 1 st surface and the 2 nd surface of the housing have the following positional relationship: when the object 100C is placed on the object surface with the outer side surface of the 1 st face portion and the object surface facing upward, the 2 nd identification information held in the 2 nd holding portion 102C of the 2 nd face portion can be read via a device provided above the object surface, and when the object 100C is placed on the object surface with the outer side surface of the 2 nd face portion in contact with the object surface, the 1 st identification information held in the 1 st holding portion 101C of the 1 st face portion can be read via a device provided above the object surface, the 2 nd identification information held in the 2 nd holding portion 102C of the 2 nd face portion facing upward.

In the case of the above-described example of the card game, the card 60SC corresponds to an example of the object 100C, the card 60 corresponds to an example of [ game medium ], and the sleeve 70C corresponds to an example of [ housing ]. The front portion 71C and the rear portion 72C of the sleeve 70C correspond to examples of [ 1 st portion ] and [ 2 nd portion ].

The 1 st code 77C-1 and the 2 nd code 77C-2 correspond to examples of the 1 st holding unit 101C and the 2 nd holding unit 102C. The sleeve ID corresponds to an example of [ 1 st specifying information ] and [ 2 nd specifying information ]. In the case of the modified example in which the front-back surface marks are embedded in the 1 st code 77C-1 and the 2 nd code 77C-2, respectively, the front-back surface marks correspond to the [ 1 st specifying information ] and the [ 2 nd specifying information ] as examples.

[ 4-5-2 ] the 1 st image pickup section 110C is realized by the 1 st image pickup device 30C-1. The 1 st imaging unit 110C images a target surface on which the target 100C is placed. For example, the 1 st image pickup unit 110C picks up an image of the target surface from above the target surface. The 1 st image pickup unit 110C may be an image pickup unit that can pick up an image of the entire object surface, or may be an image pickup unit that can pick up only an area in the object surface where the object 100C is likely to be placed. The 1 st captured image acquiring unit 120C acquires the captured image of the 1 st capturing unit 110C.

[ 4-5-3 ] the 2 nd imaging section 180C is realized by the 2 nd imaging device 30C-2. The 2 nd imaging unit 180C images the target surface on which the target 100C is placed. The 2 nd image pickup unit 180C includes a light source for irradiating the object surface with invisible light, and an image sensor for picking up reflected light (invisible light) reflected by the object surface or the object 100C placed on the object surface, converting the reflected light into an electronic image signal, and outputting the electronic image signal. For example, the 2 nd imaging unit 180C images the target surface from above. The 2 nd imaging unit 180C may be an imaging unit that can image the entire object surface, or may be an imaging unit that can image only a region of the object surface where the object 100C is likely to be placed. The 2 nd captured image acquiring unit 190C acquires the captured image of the 2 nd capturing unit 180C.

[ 4-5-4 ] the reading section 130C reads the 1 st specifying information held in the 1 st holding section 101C. The reading unit 130C reads the 1 st specifying information from the captured image of the 2 nd imaging unit 180C. Further, the reading section 130C reads the 2 nd specifying information held in the 2 nd holding section 102C. The reading unit 130C reads the 2 nd specifying information from the captured image of the 2 nd imaging unit 180C.

When the object 100C is placed on the target surface such that the 1 st surface of the object 100C (container) is in contact with the target surface, the 2 nd identification information held by the 2 nd holding unit 102C on the 2 nd surface of the object 100C can be read by the reading unit 130C. On the other hand, when the object 100C is placed on the target surface so that the 2 nd face of the object 100C (storage body) is in contact with the target surface, the 1 st identification information held by the 1 st holding unit 101C on the 1 st face of the object 100C can be read by the reading unit 130C.

In the above-described example of the card game, when the card 60SC is placed with the front side facing upward, the 1 st code 77C-1 is captured in the captured image of the 2 nd imaging device 30C-2, and therefore the reading section 130C reads the sleeve ID (or the front-back surface mark) embedded in the 1 st code 77C-1. On the other hand, in the case where the card 60SC is placed with the back face facing upward, the 2 nd code 77C-2 is captured in the captured image of the 2 nd imaging device 30C-2, and therefore the reading section 130C reads the sleeve ID (or the front-back mark) embedded in the 2 nd code 77C-2.

[ 4-5-5 ] the determination unit 150C determines the position and state of the object 100C based on the image captured by the 1 st image capture unit 110C and the reading result of the reading unit 130C. The determination section 150C includes a 1 st determination section 151C and a 2 nd determination section 152C.

For example, the 1 st specifying unit 151C specifies the position and orientation of the object 100C based on the captured image of the 1 st imaging unit 110C. The 2 nd specifying unit 152C specifies the position and the type of the object 100C based on the reading result of the reading unit 130C. The 2 nd specification unit 152C may specify the position, type, and orientation of the object 100C based on the reading result of the reading unit 130C.

In the case of the above-described example of the card game, the 1 st specifying unit 151C specifies the position, the vertical and horizontal directions, and the front and back directions of the card 60SC based on the captured image of the 1 st imaging unit 110C. Further, the 2 nd specifying unit 152C specifies the position of the card 60SC and the card ID based on the reading result of the reading unit 130C.

[ 4-5-6 ] the 2 nd surface portion of the object 100C (storage body) may include a 3 rd holding portion provided so as to have a predetermined positional relationship with the 2 nd holding portion 102C.

That is, as in the modification described above, a plurality of codes 77C may be printed on the back surface portion 72C, as in the 1 st IC tag 73A-1 and the 2 nd IC tag 73A-2 of embodiment 2. That is, the back surface portion 72C may include, in addition to the 2 nd code 77C-2, a 3 rd code (an example of the 3 rd holding portion) having a predetermined positional relationship with the 2 nd code 77C-2.

In this case, the 2 nd code 77C-2 and the 3 rd code are disposed at different positions on the outer surface of the back surface portion 72C, as in the 1 st IC tag 73A-1 and the 2 nd IC tag 73A-2 according to embodiment 2. The 2 nd codes 77C-2 and 3 rd codes are arranged at positions where the orientation of the card 60SC can be determined from the positional relationship of the 2 nd codes 77C-2 and 3 rd codes when the card 60SC is placed on the game field in a face-up manner.

In this way, when the card 60SC is placed with the back surface facing upward, the vertical and horizontal orientations of the card 60SC can be determined based on the positional relationship between the 2 nd code 77C-2 and the 3 rd code. The same applies to the front face portion 71C.

Modifications [5 ] the present invention is not limited to the above-described embodiments 1 to 4.

[ 5-1 ] for example, embodiment 2 may be combined with embodiment 3. That is, 1 sleeve may be provided with an IC tag for specifying the vertical and horizontal directions in addition to the IC tag for specifying the front and rear directions. For example, 3 or 4 or more IC tags may be provided to 1 sleeve. In this case, the imaging device 30 is not necessarily required to specify the position and state (position, vertical and horizontal directions, front and rear directions) of the card 60.

For example, as in the case of the sleeve 70A shown in fig. 23, the 1 st IC tag and the 2 nd IC tag corresponding to the 1 st IC tag 73A-1 and the 2 nd IC tag 73A-2 may be provided on the inner surface of the back surface portion of the sleeve, and further, only the blocking surface portion corresponding to the lower half of the blocking surface portion 74B shown in fig. 29 may be provided in the sleeve, and the 3 rd IC tag corresponding to the 1 st IC tag 73B-1 shown in fig. 29 may be provided on the surface of the blocking surface portion corresponding to the 1 st surface 75B shown in fig. 29.

In this case, since there is a blocking surface portion between the 2 nd IC tag and the 3 rd IC tag existing on the lower half portion of the sleeve, when the card 60 accommodated in the sleeve is placed in the game field F with the front side facing upward, the reading device 20 receives a signal from the 2 nd IC tag, the reading device 20 does not receive a signal from the 3 rd IC tag, and when the card 60 accommodated in the sleeve is placed in the game field F with the back side facing upward, the reading device 20 receives a signal from the 3 rd IC tag, and the reading device 20 does not receive a signal from the 2 nd IC tag. As a result, it is possible to determine whether the card 60 accommodated in the sleeve is placed with the front side facing upward or the back side facing upward, based on which signal from the 2 nd IC tag or the 3 rd IC tag the reader 20 receives.

In this case, since the 1 st IC tag existing in the upper half of the sleeve is not affected by the blocking face, the signal from the 1 st IC tag is received by the reader device 20 regardless of whether the card 60 accommodated in the sleeve is placed in the game field F with the front side up or the back side up. As a result, when the card 60 housed in the sleeve is placed so as to face upward, the signals from the 1 st IC tag and the 2 nd IC tag are received by the reading device 20, and the positions of the 1 st IC tag and the 2 nd IC tag can be specified, so that the vertical and horizontal directions of the card 60 can be specified from the positional relationship between the 1 st IC tag and the 2 nd IC tag. On the other hand, when the card 60 housed in the sleeve is placed with its back surface facing upward, the signals from the 1 st IC tag and the 3 rd IC tag are received by the reading device 20, and the positions of the 1 st IC tag and the 3 rd IC tag can be specified, so that the orientation of the longitudinal and lateral directions of the card 60 can be specified from the positional relationship between the 1 st IC tag and the 3 rd IC tag.

As described above, according to the sleeve including the 3IC tags (1 st to 3 rd IC tags) as described above, the front-back direction of the card 60 placed on the game field F can be determined based on the reading result of the reading device 20, and the vertical and horizontal directions of the card 60 can be determined based on the reading result of the reading device 20 regardless of which of the front-back direction the card 60 is placed.

For example, 2IC tags corresponding to the 1 st IC tag 73A-1 and the 2 nd IC tag 73A-2 shown in fig. 23 may be provided on the 1 st surface 75B of the blocking surface portion 74B and the 2 nd surface 75B of the blocking surface portion 74B (or the inner surface of the back surface portion 72B of the sleeve 70B) in the sleeve 70B shown in fig. 29, whereby 4 IC tags may be provided on 1 sleeve. In this way, the front-back orientation of the card 60 placed in the playard F can also be determined based on the reading result of the reading device 20, and the longitudinal-lateral orientation of the card 60 can be determined based on the reading result of the reading device 20 regardless of whether the card 60 is placed with the front side facing upward or the back side facing upward.

[ 5-2 ] for example, any one of embodiment 1 to embodiment 3 may be combined with embodiment 4. That is, the sleeve (or the card 60) may be provided with both the IC tag and the invisible code.

[ 5-3 ] the description has been given mainly on the card game, but the present invention can be applied to games other than the card game. The present invention can be applied to a game played using an object placed on an object surface.

According to the invention described in a2), since the object corresponding to the type of the object placed on the object surface is displayed on the display means in the state corresponding to the state of the object placed on the object surface, a person (audience or the like) who views the display means can easily grasp the current state of the game.

A3) In one embodiment of the present invention, the display device may further include a unit (160) that causes a display unit (170) to display an object corresponding to the type of the object specified by the specifying unit (150, 150A, 150B) based on the state of the object specified by the specifying unit (150, 150A, 150B).

According to the invention described in a3), for example, it is possible to determine whether or not to display the object corresponding to the type of the object specified by the specifying means, based on the state of the object specified by the specifying means. For example, the object corresponding to the type of the object specified by the specifying means may be displayed or the object corresponding to the type of the object specified by the specifying means may not be displayed in accordance with the state of the object specified by the specifying means.

A4) In one aspect of the present invention, the object has a recording surface (e.g., 61) on which information is recorded, the specifying means (150, 150A, 150B) specifies a type of the object placed on the object surface based on the information read by the reading means (130), and specifies the information recorded on the recording surface of the object placed on the object surface based on a result of the specifying, and the display control unit (160) displays a display corresponding to the information recorded on the recording surface of the object specified by the specifying means on a display unit (170) when the object is placed on the object surface such that the recording surface faces the object surface.

According to the invention described in a4), even when the object is placed on the object surface such that the recording surface faces the object surface (that is, when the object is placed on the object surface in a state in which the information described on the recording surface is not visible), a display corresponding to the information described on the recording surface of the object is displayed on the display unit, and therefore, it is possible to provide a new interest for a person (viewer or the like) viewing the display unit to be able to know something that is not originally known.

A5) In one embodiment of the present invention, the display control unit (160) includes a means for displaying on the display means (170) an object (for example, PB-1, PB-2) corresponding to the object placed on the object surface, and when a predetermined operation related to the object corresponding to the object is received in a state where the object is placed on the object surface so that the storage surface faces the object surface, a display (for example, PC) corresponding to the information stored on the storage surface of the object may be displayed on the display means (170).

According to the invention described in a5), when the object is placed on the object surface so that the recording surface faces the object surface (that is, when the object is placed on the object surface in a state where the information described on the recording surface is invisible), and when a predetermined operation related to an object corresponding to the object is accepted, a display corresponding to the information described on the recording surface of the object is displayed on the display unit.

A6) In one embodiment of the present invention, the identifying means (150, 150A, 150B) may identify a type of the 1 st object placed on the object surface in a stacked state by the 2 nd object based on the information read from the IC tag of the 1 st object by the reading means (130).

According to the invention described in a6), even when the 2 nd object is stacked on the 1 st object, the type of the 1 st object can be specified. In the case where the 2 nd object is layered on the 1 st object, it is difficult to specify the type of the 1 st object from the captured image, but according to the present invention, the type of the 1 st object can be specified.

A7) In one embodiment of the present invention, the reading unit (130) includes a plurality of antennas (e.g., 20-10 to 20-30 or 21 and 22), the plurality of antennas (e.g., 20-10 to 20-30 or 21 and 22) are antennas that receive signals transmitted from the IC tag, and are provided in correspondence with a plurality of positions on the object surface, respectively, and the determining unit (150) may determine the position of the object placed on the object surface based on which of the plurality of antennas the signal transmitted from the IC tag of the object placed on the object surface is received.

According to the invention described in a7), the position of the object placed on the object surface can be determined based on which of the plurality of antennas the signal transmitted from the IC tag of the object placed on the object surface is received. For example, the position of the object placed on the object surface may be determined from the captured image, but according to the invention described in a7), the position of the object placed on the object surface can be determined not only from the captured image but also from which of the plurality of antennas the signal transmitted from the IC tag of the object placed on the object surface is received. Further, by collating them, even in the case where a plurality of objects are placed on the object face, it can be determined that the determination result based on the captured image of the capturing unit and the determination result based on the reading result of the reading unit are determination results regarding the same object placed on the object face.

For example, it is possible to determine from the captured image which of the 1 st face and the 2 nd face is to be placed on the target surface so as to face the target surface, but according to the invention described in A8), it is possible to determine from not only the captured image but also from the read results of the information stored in the 1 st IC tag and the 2 nd IC tag of the target that the target is to be placed on the target surface so as to face the target surface, and therefore, by comparing these, it is possible to improve the accuracy of the determination result of which of the 1 st face and the 2 nd face is to be placed on the target surface so as to face the target surface.

A9) In one aspect of the present invention, the object (100A) may include: 1 st IC tag (e.g., 73A-1); a 2 nd IC tag (for example, 73A-2) provided so as to have a predetermined positional relationship with the 1 st IC tag, wherein the reading unit (130) includes a plurality of antennas (for example, 21 and 22), the plurality of antennas (for example, 21 and 22) receive signals transmitted from the 1 st IC tag and the 2 nd IC tag, respectively, and are provided so as to correspond to a plurality of positions on the object surface, respectively, and the determining unit (150A) determines the orientation of the object placed on the object surface based on which of the plurality of antennas the signals transmitted from the 1 st IC tag and the 2 nd IC tag of the object placed on the object surface are received.

According to the invention described in a9), the orientation of the object placed on the object surface can be determined based on which of the plurality of antennas the signal transmitted from each of the 1 st IC tag and the 2 nd IC tag of the object placed on the object surface is received. For example, the direction of the object placed on the object surface may be determined from the captured image, but according to the invention described in a9), the direction of the object placed on the object surface may be determined not only from the captured image but also from which of the plurality of antennas the signal transmitted from each of the 1 st IC tag and the 2 nd IC tag of the object is received, and therefore, by collating these, the accuracy of the determination result of the position of the object placed on the object surface can be improved.

A10) In one embodiment of the present invention, the determination unit (150, 150A, 150B) may include: a1 st determination unit (151, 151A, 151B) that determines a position and an orientation of the object placed on the object surface from the captured image of the capturing unit (110); and a 2 nd specifying unit (152, 152A, 152B) that specifies a position and a kind of the object placed on the object surface based on a reading result of the reading unit (130), and specifies a combination of a result of the determination by the 1 st specifying unit and a result of the determination by the 2 nd specifying unit with respect to the same object placed on the object surface based on the position specified by the 1 st specifying unit and the position specified by the 2 nd specifying unit.

According to the invention described in C2), since the IC tag is provided at a position other than the facing surface portion, it is possible to prevent the information described on the recording surface of the game medium stored in the storage body from being hidden by the IC tag and being difficult to see.

C3) In one embodiment of the present invention, the housing (e.g., 70A, 70B) may include an opposite surface (e.g., 72A, 72B) located on an opposite side of the opposite surface, and the IC tag (e.g., 73A-1, 73A-2, 73B-1, 73B-2) may be provided on the opposite surface.

According to the invention described in C3), since the IC tag is provided on the opposite surface portion located on the opposite side to the opposite surface portion, it is possible to prevent the information described on the recording surface of the game medium stored in the storage body from being hidden by the IC tag and being difficult to see.

C4) In one aspect of the present invention, the opposite surface (e.g., 72A, 72B) may have the same appearance as the opposite surface of another housing.

According to the invention described in C4), it is possible to ensure that the respective containers cannot be distinguished from the opposite side surface portion provided with the IC tag.

C5) In one embodiment of the present invention, the electronic device may include a 1 st IC tag (for example, 73A-1) and a 2 nd IC tag (for example, 73A-2) provided so as to have a predetermined positional relationship with the 1 st IC tag.

According to the invention described in C5), the orientation of the game medium placed on the target surface in the state of being accommodated in the accommodation body can be determined. That is, by providing 1 or more antennas provided corresponding to a plurality of positions on the target surface as antennas for receiving signals transmitted from the 1 st IC tag and the 2 nd IC tag, respectively, it is possible to specify the positions of the 1 st IC tag and the 2 nd IC tag according to which position the signals transmitted from the 1 st IC tag and the 2 nd IC tag of the housing placed on the target surface are received by the antennas, and it is possible to specify the orientation of the housing placed on the target surface (game medium housed in the housing) based on the positional relationship between the 1 st IC tag and the 2 nd IC tag.

C6) In one embodiment of the present invention, the present invention may further include: 1 st face (e.g., 71B); face 2 (e.g., 72B); 1 st IC tag (e.g., 73B-1); 2 nd IC tag (e.g., 73B-2); and a restricting unit (103B: e.g., 74B) that restricts communication between a reading unit (130: e.g., 20-1 to 20-30) that reads the identification information held in the 1 st IC tag or the 2 nd IC tag and the 1 st IC tag and restricts communication between the reading unit (130) and the 2 nd IC tag via the 1 st face, wherein the 1 st IC tag is disposed between the 1 st face and the restricting unit and the 2 nd IC tag is disposed between the 2 nd face and the restricting unit.

According to the invention described in C6), it can be determined, based on the result of reading the identification information held in the 1 st IC tag and the 2 nd IC tag, whether the game medium stored in the storage body is placed on the target surface so that the 1 st face or the 2 nd face of the storage body comes into contact with the target surface. For example, in a case where the reading unit is disposed below the target surface, when the game medium stored in the storage body is placed on the target surface such that the 1 st face of the storage body is in contact with the target surface, the reading unit reads the identification information held in the 1 st IC tag out of the 1 st IC tag and the 2 nd IC tag. On the other hand, in a case where the game medium stored in the storage body is placed on the target surface in such a manner that the 2 nd face portion of the storage body comes into contact with the target surface, the determination information held in the 2 nd IC tag out of the 1 st IC tag and the 2 nd IC tag is read by the reading unit. Therefore, according to the invention described in C6), it is possible to determine, based on the determination information held in which of the 1 st IC tag and the 2 nd IC tag is read by the reading unit, which of the 1 st face and the 2 nd face of the housing is to be placed on the target face so that the game medium housed in the housing is in contact with the target face.

C7) An object (for example, 80) according to another aspect of the present invention is an object (for example, 80) that is stored in a storage (for example, 70A, 70B) together with each game medium used in a game played using a game medium (for example, 60) placed on a target surface (for example, a playfield F), the object including an IC tag (for example, 73A-1, 73A-2, 73B-1, 73B-2) for holding identification information for identifying a kind or a state of the game medium placed on the target surface in a state of being stored in the storage.

According to the invention recited in C7), since the IC tag for holding the identification information for identifying the type or state of the game medium placed on the target surface in the state of being housed in the housing is provided on the object housed in the housing together with the game medium, the identification information held in the IC tag can be read by the IC tag reader when used in the state of being housed in the housing, thereby enabling the type or state of the game medium placed on the target surface in the state of being housed in the housing to be identified based on the read identification information.

Further, according to the invention described in C7), it is not necessary to provide the game medium itself with a special configuration for enabling (or facilitating) specification of the type or state of the game medium placed on the target surface, and an existing game medium (a game medium not having the above-described special configuration) can be used for the game.
