Technical Field

The present invention relates to a game system for playing a game by placing medals on any one of a plurality of placement objects laid out on a table.

Background

Conventionally, there is known a system in which, on a table on which a game is played by placing tokens on any one of placement objects laid out on the table, a camera captures a token on the table to acquire a captured image, and an image analysis device analyzes the captured image to specify a placement object on which the token is placed, and the type and number of tokens, thereby specifying how many tokens are placed on which placement object.

A plurality of player positions are provided on such a table to enable a plurality of players to play simultaneously. On the table, a placement area is provided at each player position. Various placement objects are laid out in each placement area. A player playing a game at a player position places a medal on any one of a plurality of placement objects laid out in a placement area allocated to the player position of the player by placing the medal on the placement object. In the case where a plurality of medals are placed on the placement object, the plurality of medals are stacked and placed on the placement object in a pile.

Therefore, by providing the image analyzing device based on the division of the placement area at each player position, it is possible to determine how many medals are placed on which placement object for each player position. For example, at least "player" and "dealer" are provided at each player position on a table for a certain card game as various placement objects. The game system can determine whether the player at each player position places "player" or "banker" by performing image analysis on the captured image, and further determine the placement amount (for example, japanese patent application laid-open No. 2019-149155).

On the basis of the system, further by using a player determination system that determines a player, it is possible to determine which player has placed how many medals on which placement object. In addition to this, by using a game result determination system that determines the result of the game, it is possible to determine which player has placed how many medals, received the repayment of how many medals, and how many medals have been collected.

In the case where a plurality of player positions are provided on the table, it does not mean that a player cannot play a game without sitting at any of the player positions. In particular, when all the player positions previously arranged on a certain table are used, there are cases where: a player who is not seated at a player position participates in a game by placing his or her own medal in a placement area allocated to a player who plays the game at the player position (hereinafter, referred to as "main player"). The case where a player who is not seated at the player position places any one of the placement objects in the placement area assigned to the player who is seated at the player position is referred to as "post placement", and the player who performs post placement is referred to as "post player".

As a result of such post-placement, a plurality of players should place coins on the placement area allocated for each player position, and as a result, a plurality of stacks of coins exist on the same placement object in one placement area or a plurality of placement objects different from each other. In such a case, it is difficult to determine which of a plurality of stacks of medals placed in the same placement area is the stack of the main player and which stack is the stack of the succeeding player.

Disclosure of Invention

Accordingly, the present invention provides a game system capable of determining which of a plurality of stacks of medals placed by a plurality of players in the same placement area is the stack placed by which player.

A game system according to an embodiment of the present invention includes: a table having a placement area in which a plurality of placement objects are laid out; a camera that photographs the table and generates a photographed image; and an information processing device that determines, based on the captured image and based on a position of a stack of game coins within the captured image, on which placement object the stack is placed; the information processing device determines which of the plurality of bundles is a bundle of a main player and which of the bundles is a bundle of a rear player, based on the captured image, when a plurality of bundles of medals are placed in the same placement area.

According to this configuration, even when a plurality of pieces of medals are placed in the same placement area, it is possible to determine which piece is the piece of the main player and which piece is the piece of the player placed behind.

In the above game system, the information processing device may determine which of the plurality of stacks placed in the same placement area is a stack of the main player and which of the plurality of stacks is a stack of the succeeding player based on a positional relationship between the plurality of stacks.

According to this configuration, even if a plurality of pieces of medals are placed in the same placement area, it is possible to determine which piece of medal is the piece of the main player and which piece of medal is the piece of the succeeding player, based on the relative positional relationship between the pieces of medal. For example, when a game is played with a rule that the rear deck is set to be placed on the right side of the main deck on the casino side, it is possible to determine that the stack placed on the left side is a stack of the main player and the stack placed on the right side is a stack of the rear deck players.

In the above game system, the information processing device may determine which of the bundles is a bundle of the main player and which of the bundles is a bundle of the rear players, based on a positional relationship between the bundle and the placement object on which the bundle is placed.

With this configuration, it is possible to determine which player the bundle is placed at the position of the placement object. For example, when the casino side sets a rule that the main placement is placed at the center and near the left of the placement object and the rear placement is placed at the right end of the placement object, and plays the game, it is possible to determine that the stack placed at the center and near the left of the placement object is the stack of the main player placement and the stack placed at the right end of the placement object is the stack of the rear player placement. Further, even when the following player does not place the stack and only the stack on which the main player is placed exists in the placement object, the stack can be determined as the stack of the main player based on the position where the stack is placed.

In the above game system, the camera may capture an image of a player placing a stack of the medals, and the information processing device may identify each player placing the plurality of stacks placed in the same placement area in the captured image, and determine which stack is a stack of the main player and which stack is a stack of the succeeding player based on a result of the identification.

With this configuration, it is possible to identify the player on which the pile is placed, determine which player is the main player and which player is the rear player, and further determine which pile is the pile of the main player and which pile is the pile of the rear player.

In the game system, the information processing device may recognize a part of a body or a part of clothes of each player who lays the plurality of bundles laid in the same laying area in the captured image, and determine which bundle is a bundle of the main player and which bundle is a bundle of the rear players based on a recognition result of the part of the body or the part of the clothes.

According to this configuration, even when the casino side does not set rules for the positions of the set bundles and the player freely sets the bundles on the set object to play the game, which bundle is the bundle of which player can be determined based on the part of the body or the part of the clothing recognized from the captured image.

In the above game system, the information processing device may determine which of the recognized parts of the body or clothes is which of the players' parts of the body or clothes is, and determine which of the stacks is the stack of the main player and which of the stacks is the stack of the rear player based on a result of the determination.

According to this configuration, it is possible to determine which stack of the part of the body or the part of the clothing is placed, after identifying which part of the body or the part of the clothing is which player.

In the above game system, the information processing device may determine the direction of the recognized part of the body or part of the clothing, and determine which of the stacks is the stack of the main player and which of the stacks is the stack of the rear player based on the determination result.

According to this configuration, even when it is difficult to recognize faces of the main player and the rear player, or to recognize a part of the body or clothes, for example, which stack is the player can be determined according to the extending direction of the part of the body or the part of the clothes of the stack.

In the above game system, the information processing apparatus may determine whether or not a plurality of stacks placed in the same placement area are stacks of the same player based on the captured image.

According to this configuration, even when a plurality of stacks are placed by one player or when a plurality of players are placed in a stack, for example, because the placement amount is large, which stack is which player can be determined.

In the above game system, the information processing device may determine whether or not the plurality of bundles are bundles of the same player based on the distances of the plurality of bundles.

According to this configuration, for example, the following determination can be made: if the stacks are close to each other, the stacks are stacks laid by the same player, and therefore, if the stacks are far from each other, the stacks are stacks laid by a plurality of players.

In the above game system, the information processing device may determine which of the bundles is a bundle of the main player and which of the bundles is a bundle of the rear players, based on the plurality of captured images acquired in time series.

According to this configuration, it is possible to distinguish which stack is which player from which stack, not only from one captured image, but also from a plurality of images acquired in time series, that is, similar images or the like.

In the above game system, the information processing device may determine which of the plurality of bundles placed in the same placement area is a bundle of the main player and which of the plurality of bundles is a bundle of the rear players

According to this configuration, for example, in the case where the casino side is set to a rule that the main player places first and then places the players, it is possible to determine that the stack placed first is a stack of the main player and the stack placed next is a stack of the players placed next.

ADVANTAGEOUS EFFECTS OF INVENTION

According to the present invention, even when a plurality of pieces of medals are placed in the same placement area, it is possible to determine which piece is the piece of the main player and which piece is the piece of the succeeding player.

Detailed Description

Hereinafter, a game system according to the present invention will be described in detail with reference to the drawings. In the following embodiments, a game system for a certain card game will be described as an example, but the present invention is not limited to the embodiments. Further, the components in the following embodiments include components that can be easily conceived by those skilled in the art or substantially the same components.

Fig. 1 is a diagram showing a configuration of a game system according to a first example of the embodiment of the present invention. The game system 1 includes a substantially oval game table 2. The main player 3m and the rear player 3b (hereinafter, the main player 3m and the rear player 3b are collectively referred to as "player 3") are located on one side (lower side in fig. 1) of the game table 2, and the dealer (not shown) is located on the opposite side. A plurality of placement areas 6a to 6f (hereinafter, collectively referred to as "placement areas 6") are defined on the upper surface of the game table 2 so as to correspond to each of the plurality of player positions. Further, a plurality of kinds of placement objects are laid out in the placement area 6. In each placement area 6, a free sub-area 7a, a banker sub-area 7b, a hand area 7c, a free win area 7d, and a banker win area 7e are laid out as placement objects 7. The main player 3m and the rear placement player 3b participate in the game by placing the medal 8 on any one of the placement objects 7 laid out in the placement area 6, thereby placing the medal 8 on the placement object 7. The placed game chip 8 may be one piece or a plurality of pieces. In the case where a plurality of medals 8 are placed, the medals 8 are stacked to form one or more mountains of the medals 8. Hereinafter, the mountain of the medal 8 is referred to as a stack 80. The stack 80 may also be comprised of one token 8.

The game system 1 includes a camera 10, and the camera 10 captures an image of the placement area 6 and generates a captured image 11. Further, the game system 1 includes the information processing device 12, and the information processing device 12 determines whether the bundle 80 is a bundle of the main player 3m (hereinafter referred to as "main placement") or a bundle of the post-player 3b (hereinafter referred to as "post placement") based on the captured image 11. Alternatively, the information processing device 12 may determine the position of the stack 80 of the medals 8 placed on the placement object 7 without determining whether the medal is placed mainly or after.

In the description, for convenience, 4 cameras 10a to 10d are illustrated in fig. 1, but the number and positions of the cameras 10 may be any number or positions as long as they can sufficiently photograph the placement area 6 and the stack 80 placed in the placement area 6. The camera 10b photographs the placement area 6 of the game table 2 and the medal 8 placed on the placement area 6 from directly above the game table 2. Although only the surface of the uppermost medal 8 of the stack 80 can be observed in the image of the camera 10b, the position of the stack 80 can be easily determined from the images of the other cameras 10.

Fig. 2 is a diagram showing a first example of a captured image 11a generated by capturing an image of the placement area 6 by the camera 10. A method of recognizing the bundle 80 by the information processing apparatus 12 will be described with reference to fig. 2. The captured image 11a shown in fig. 2 is composed of a plurality of pixels arranged in two-dimensional coordinates.

As a precondition, the game chip 8 is at least partially colored. The color may be formed as a layer of the medal 8, may be added to the circumferential direction of the side surface of the medal 8, or may be added as a predetermined mark to the surface of the medal 8. In fig. 2, an example in which colors are added to the circumferential direction of the side surface of the medal 8 is illustrated. The color indicates the kind (value) of the medal 8. That is, the medal 8 is applied with a color corresponding to the kind (value).

The information processing apparatus 12 detects the bundle 80 from within the image using the neural network learned for detecting the bundle 80. Specifically, the information processing apparatus 12 detects (object detects) a rectangular region 9 (bounding box) including the bundle 80 or extracts (area-divides) a region (hereinafter, referred to as "bundle region") of the bundle 80 from within the image.

The information processing device 12 extracts the area in which the partially applied color is recorded, and determines the type of each token 8 based on the partially applied color of each token 8 included in the detected stack 80. In this determination, template matching may be used, or a mechanical learning pattern such as a neural network may be used. Two of these may be used in combination, or may be used separately and subjected to stepwise determination.

Furthermore, the information processing device 12 may identify the type of the medal 8 forming the stack 80 or the stack 80 by a method of measuring the characteristics on the image having the same shape, brightness, saturation, and color from the result of the image analysis of the captured image 11 without using an artificial intelligence device.

Next, a method of identifying which of the placement objects 7 the bundle 80 is placed on will be described. Fig. 3 is a diagram showing a part of an image captured by the camera 10b directly above the game table 2. In this image, the uppermost token 8 of the stack 80 appears circular under observation. The information processing device 12 defines a two-dimensionally arranged grid for the image, and defines for each grid which placement object 7 the grid corresponds to. The information processing device 12 determines on the basis of the image detection of the stack 80 which mesh the detected stack 80 (specifically, the center of the uppermost medal 8 of the stack 80) is located in, and determines on which placement object 7 the stack 80 is placed. Further, it is also possible to determine which grid the bundle 80 is located on the basis of the photographed image shown in fig. 3, and to determine at which position within the placement object 7 the bundle 80 is placed.

The information processing device 12 determines which placement object 7 the bundle 80 is placed on based on the captured image 11a shown in fig. 2, as follows. That is, as shown in the photographed image 11a of fig. 2, when a photographed image obtained by photographing from an obliquely upper side is used, the information processing device 12 determines a position where the bundle 80 is placed (that is, a position within the placement object 7 or a position within the placement object 7) based on the coordinate value of the pixel at the center of the bottom side of the detected rectangular region 9 or the lowest point of the center of the extracted left-right maximum width of the bundle region.

Alternatively, when the position at which the bundle 80 is placed (that is, the placement object 7 or the position within the placement object 7) is determined from the captured image 11a as shown in fig. 2, the information processing device 12 determines that the bundle 80 is present on the coordinates of the center in the left-right direction of the color added in the circumferential direction of the side surface of the lowermost medal 8. Alternatively, the position of the stack 80 may be determined by specifying the coordinates of the center of the medal 8 by estimating the overall shape of the medal 8 based on the arc-like shape of the color added in the circumferential direction.

The information processing device 12 can store which coordinate corresponds to which placing object 7, and can identify which placing object 7 the stack 80 is placed on by comparing the stored information with the coordinate indicating the center of the medal 8 determined from the captured image 11 a. The information processing device 12 may detect or extract each placement object 7 from the captured image in a mechanical learning mode such as a neural network for the placement object 7, and determine the placement object 7 on which the stack 80 is placed.

The information processing device 12 may recognize the center of the uppermost medal and the number of medals 8 in the stack 80, and based on this, estimate the position of the center of the lowermost medal of the stack 80 and set it as the position of the stack 80. In this case, the information processing device 12 calculates, as the position of the lowermost medal 8, that is, the position of the stack 80, the position of a right triangle having an inclination in which a line segment connecting the camera 10 and the center of the uppermost medal is the hypotenuse, having a height calculated based on the number of medals 8, and setting the bottom on the table surface.

The information processing apparatus 12 converts the coordinates of each pixel of the image acquired from the camera 10 into a desktop coordinate system set on the desktop. The conversion formula is determined by the relationship between the position and the posture of the table and the camera 10, and can be known as long as the camera 10 is fixed. The positions of the bundles 80 recognized in the respective images of the plurality of cameras 10 are converted into the desktop coordinate system, respectively, so that the bundles 80 photographed by the plurality of cameras 10 can be collectively processed.

The information processing apparatus 12 has a diagram of the placement object corresponding to the desktop coordinate system. The information processing apparatus 12 maps the position (coordinates) of the bundle 80 converted into the desktop coordinate system to a map (first map) in which the placement object 7 is set, thereby determining which placement object 7 the bundle 80 is located.

The information processing apparatus 12 also has a map (second map) in which a part of the placement objects (for example, the sum area 7c, the free-house winning area 7d, and the dealer winning area 7e, which are relatively large in area) is further divided into a plurality of small areas. The information processing apparatus 12 maps the position (coordinates) of the bundle converted into the desktop coordinate system to the second map, thereby determining which small area of the placement object 7 the bundle 80 is located in. As such a second map, for example, the station area 7c may be divided into three in the longitudinal direction to define three small areas, and the free win area 7d and the dealer win area 7e may be divided into four to define four small areas.

In the case where the positions of the stack 80 acquired by the plurality of cameras 10, respectively, are converted into the desktop coordinate system, an error may be generated between the conversions. This error is caused by an error in the posture or position of the camera 10, an incorrect conversion of the coordinate conversion, or a recognized position of the stack 80. When the positions of the same stack 80 photographed by the plurality of cameras 10 are respectively converted into the desktop coordinate system, the number of bits thereof can be regarded as the coordinates of the stack 80 in the case of positional deviation. In the case where the stacks 80 are photographed by the plurality of cameras 10, the information processing device 12 may regard the stacks 80 as one stack when the distance in the desktop coordinate system is equal to or less than the predetermined threshold value, and recognize the stacks 80 as two different stacks when the distance between the stacks 80 is greater than the predetermined threshold value.

In the above example, the information processing device 12 may determine which placement object or small area the bundle 80 is placed in after converting all the positions of the bundle 80 acquired by the plurality of cameras 10 into the same desktop coordinate system, and instead, may determine which placement object or small area the identified bundle 80 is placed in by mapping the position of the bundle 80 identified in the captured image 11 of each camera to the map without performing coordinate conversion by arranging the map in which each placement object or small area is set in advance in the captured image 11 of each camera 10.

Fig. 4 is a diagram showing a second example of the captured image 11b generated by capturing the placement area 6 by the camera 10. The placement area 6a and a part of the placement area 6b are illustrated in the captured image 11 b. A specific determination method of the information processing device 12 will be described with reference to fig. 1, 4, and 5.

In the placement area 6a of fig. 4, there are two stacks 80a, 80b, the stack 80a being placed in the winning combination area 7c and the stack 80b being placed in the winning free area 7 d. Now, the casino side sets a rule that the post-placement is placed on the right side where the player is placed when facing the dealer, and plays the game based on the rule to generate the captured image 11 b. In this case, the information processing device 12 determines that the bundle 80b placed in the win-or-loss area 7d is placed on the left side and the bundle 80a placed in the win-or-loss area 7c is placed on the right side of the bundle 80b based on the photographed image 11b, and further determines that the bundle 80b is placed mainly and the bundle 80a is placed afterwards based on the above-described rule.

Based on the above-described rule, even when a plurality of stacks 80 are placed because the main player 3m and the post-placement player 3b are placed in the same placement area 6, it is possible to determine whether each stack 80 is placed mainly or post-placed. The casino side may set a rule that the main placement is placed at the center and the left of the placement object 7, and the post placement is placed at the right end of the placement object 7.

Based on the above rule, the following determination can be made: even in the case where the following player 3b does not place the pile, and only a single pile or a plurality of piles 80 placed by the main player 3m exist in the placement object 7, it is possible to determine that the pile 80 is a pile of the main player 3 m; further, even in a case where the host player 3m does not perform the placement, and only a single or a plurality of stacks 80 placed by the post-player 3b exist in the placement object 7, it can be determined that the stack 80 is a stack of the post-player 3 b.

In the description, only two examples of rules set on the casino side are given, but the rules are not necessarily the same, and any rules may be set on the casino side as long as they can distinguish the post-placement player 3b from the main player 3 m.

Fig. 5 is a diagram showing a third example of the captured image 11c generated by capturing the placement area 6 by the camera 10. In the captured image 11c, in addition to the captured image 11b, a part of the hand and arm of the main player 3m and a part of the sleeve of clothing (hereinafter, simply referred to as "arm 15 a"), and a part of the hand and arm of the player 3b and a part of the sleeve of clothing (hereinafter, simply referred to as "arm 15 b") are shown (hereinafter, collectively referred to as "arm 15a and arm 15 b"). The information processing device 12 is configured to be able to recognize the arm 15 in the captured image 11 c. Further, the information processing device 12 can determine whether each arm 15 is the arm of the main player 3m or the arm of the rear player 3 b. The information processing device 12 determines whether each of the stacks 80 placed in the placement area 6 is a stack of the main player 3m or a stack of the rear player 3b based on the determination result.

Here, a method of the information processing apparatus 12 recognizing the arm 15 will be described. The method of recognizing the area of the arm 15 from the photographed image 11c is basically the same as the aforementioned method of extracting the area of the medal 8. When the medal 8 is recognized, a specific color added to the medal 8 is used as a reference, and when the arm 15 is recognized, a color or a pattern of clothes or a color of the arm is used as a reference.

The information processing device 12 captures an arm 15 of each player in advance, and stores a captured image of each arm 15 in association with information identifying the player. The information processing device 12 identifies the main player 3m and the rear player 3b by a player identification system described later. When the first arm 15 in the captured image 11c is recognized, the information processing device 12 determines which arm 15 stored in advance corresponds to the arm 15, and determines whether the arm 15 is the arm 15a of the main player 3m or the arm 15b of the post-player 3 b.

The information processing device 12 may recognize the arm 15 of the captured image 11c, and determine whether the arm 15 is the arm of the main player 3m or the arm of the player 3b placed behind, based on the recognized direction of the arm 15.

Fig. 6 is a diagram showing a photographed image 11d of a fourth example obtained by photographing the placement area 6 with the camera 10. A method of determining the direction based on the arm will be described with reference to fig. 6. The captured image 11d illustrates the respective arms 15 of the main player 3m and the rear player 3 b. The information processing device 12 first identifies the tip 14 and the end 16 of the arm 15, and connects these two points with a straight line 17. Further, the straight line 17 and a straight line 18 drawn horizontally through the tip 14 are connected. The angle 19 formed by these two straight lines 17, 18 is used as a reference for determining the player 3.

In the game, the rear player 3b plays the game in a standing state. Thus, when placed, the arm 15b is extended from a high angle toward the game table 2. On the other hand, the main player 3m plays the game while sitting. Thus, when placed, the arm 15a is extended from a low angle toward the game table 2.

That is, the information processing device 12 identifies the arm 15 with the small angle 19 obtained by the above-described method as the arm 15a of the main player 3m, and the arm 15 with the large angle 19 as the arm 15b of the rear player 3 b. The determination may be performed by other methods.

In the description, the information processing device 12 recognizes the arm 15 in the captured image 11d, but the recognition target does not necessarily have to be the arm 15 of the player 3, and may be a part other than the arm as long as it is a part of the body or a part of clothing.

As an example of recognizing a part of the body other than the arm, for example, the body of the player 3 may be captured so as to be included in the captured image 11. In this case, the body of the host player 3m sitting on the chair is identified, and further, the arm 15 extending from the body is identified. Then, the stack 80 on which the arm 15 is placed is further recognized, and the stack 80 is determined to be the stack of the main player 3 m. The same method is also used for determining the post-placement player 3 b.

In the game, when the player 3 places the medal 8, there is a case where one player 3 places the medal 8 in a plurality of stacks 80. Even in such a case, the game system 1 of the present embodiment can determine whether or not the plurality of stacks 80 are stacks of the same player 3. Hereinafter, the description will be given with reference to fig. 7.

Fig. 7 is a diagram showing a photographed image 11e of a fifth example generated by photographing the placement area 6 with the camera 10. The photographed image 11e illustrates a part of the placement area 6a and the placement area 6 b. In the placement area 6 there are two stacks 80c, 80d, which stacks 80c, 80d are placed in the sum area 7 c. The information processing device 12 measures the distances of the plurality of bundles 80c and 80d placed on the same placing object 7 based on the captured image 11 e. The distance may be a distance within the captured image 11e, and may be a distance converted from the distance of the captured image 11e to a distance in real space. Then, the information processing device 12 determines whether or not the plurality of stacks 80c, 80d are stacks 80 of the same player 3 based on the obtained distances.

Fig. 8 is a diagram showing a captured image 11f of a sixth example generated by capturing an image of the placement area 6 with the camera 10. A specific determination method will be described with reference to fig. 7 and 8. In fig. 7, the two stacks 80c, 80d are placed adjacently. In this case, the information processing device 12 determines that the distance between the bundle 80c and the bundle 80d is smaller than the predetermined threshold value, and determines that the two bundles 80c and 80d are the bundles 80 of the same player 3. On the other hand, in the captured image 11f of the sixth example in fig. 8, the two bundles 80 are placed far apart. In this case, the information processing device 12 determines that the distance between the bundle 80e and the bundle 80f is greater than the predetermined threshold value, and determines that the two bundles 80e and 80f are bundles 80 of different players 3. That is, the information processing device 12 determines whether or not the plurality of stacks 80 are stacks 80 of the same player 3 based on the distances between the plurality of stacks 80. The distance between the stacks 80 as a criterion for the information processing device 12 may be any distance.

Fig. 9 is a diagram showing a captured image 11g of a seventh example generated by capturing an image of the placement area 6 with the camera 10. A determination method in a case where three bundles 80 are placed on the same placement object 7 will be described with reference to fig. 9. In fig. 9, three stacks are placed in the sum area 7 c. The stack 80g is positioned adjacent to the stack 80h and the stack 80i is positioned further apart. In this case, the information processing apparatus 12 uses the distance between the bundle 80g and the bundle 80h, or the distance between the bundle 80h and the bundle 80i as a determination criterion. That is, the information processing device 12 determines that the bundle 80g and the bundle 80h are bundles on which the player 3 is placed, and the bundle 80i is a bundle on which the other player 3 is placed. The distance as a criterion for determination by the information processing device 12 may be any distance.

Although two stacks 80 are illustrated in fig. 7 and 8, and three stacks 80 are illustrated in fig. 9, the number of stacks 80 may be four or more.

The determination by the information processing apparatus 12 described above is to determine whether the plurality of stacks 80 are placed mainly or after each shot image, but the information processing apparatus 12 may determine based on a plurality of shot images. The cameras 10 included in the game system 1 capture images of the placement area 6 at regular intervals and generate captured images. The captured images can be acquired in time series. Therefore, in the case where a plurality of bundles 80 are placed in the same placement area 6, the information processing device 12 can determine whether or not the plurality of bundles 80 are bundles 80 of the same player 3 based on a plurality of captured images acquired in time series.

FIG. 10 is a view showing six captured images 11h 1-11 h6 acquired in time series in the order of lines 1-6. A specific determination method based on a plurality of captured images will be described with reference to fig. 10. The photographed images 11h1 and 11h2 show a state in which the first player 3 intends to place the plurality of medals 8 in the placement area 6. The photographed image 11h3 shows a state in which the first player 3 places the plurality of game chips 8 in the dealer sub-area 7b of the placement area 6, thereby placing the dealer sub-area 7 b. The photographed images 11h4 and 11h5 show a state in which the second player 3 intends to place the plurality of medals 8 in the placement area 6. The photographed image 11h6 shows a state in which the second player 3 places the plurality of game pieces 8 in the sum-hand area 7c of the placement area 6, thereby placing the sum-hand area 7 c. The captured image 11h6 shows a state in which the bundle 80 created by the placement of the first player 3 and the bundle 80 created by the placement of the second player 3 are placed, and a plurality of bundles 80 are present in the same placement area 6.

For example, when the casino side sets the rule that the post-placement is the placement after the main placement, and the game is played, and then six photographed images 11h1 to 11h6 are obtained, the information processing device 12 determines that the medal 8 placed by the first player 3 is the stack 80 of the main player 3m, and the medal 8 placed by the second player 3 is the stack 80 of the post-player 3 b.

Note that, although one rule is described in the description, the rule set on the casino side may be any rule as long as the rule is a rule that allows the player 3b and the host player 3m to be placed after being distinguished from each other.

Note that, there is a case where the main player 3m and the following player 3b place a plurality of stacks 80, respectively. In this case, if the player 3b simply determines the second stack 80 on which the main player 3m is placed as the stack on which the following player 3b is placed. Therefore, in order to determine whether the second and subsequent stacks 80 are placed by the main player 3m or the post-player 3b, the information processing device 12 may determine as follows.

The camera 10 continuously captures a plurality of images, and gives a time-series captured image 11 to the information processing apparatus 12. When another stack 80 is placed within a predetermined time (for example, within 2 seconds) after the first stack 80 is placed, the information processing device 12 determines that these stacks 80 are stacks on which the same player is placed. Thus, for example, when three stacks 80 exist in the same placement area 6, it is possible to determine whether the second stack 80 is a stack on which the leading player 3m has placed or a stack on which the trailing player 3b has placed.

Even in the case where a plurality of stacks 80 exist in the same placement area 6, there is a possibility that all of the stacks are stacks placed by the main player 3 m. In this case, if the second stack 80 is placed within a prescribed time after the first stack 80 is placed, the information processing apparatus 12 can recognize that the first stack and the second stack are stacks placed by the same player, and if the third stack is placed within a prescribed time after the second stack is placed, the information processing apparatus 12 can recognize that the second stack and the third stack are stacks placed by the same player.

In addition, in the case where a plurality of the stacks 80 exist in the same placing area 6, the information processing apparatus 12 can determine whether or not these stacks 80 are the stacks placed by the same player based on the number and number of tokens 8 of the stacks 80. For example, when there are a stack 80 of 10 medals (total of 100,000 points) of 10,000 points and a stack 80 of 2 medals of 1,000 points, it can be determined that these stacks are stacks placed by different players. The reason for this is that a player who placed 100,000 points does not easily think of placing 1,000 points again to put 101,000 points in total. Note that, in this case, the information processing apparatus 12 may recognize the stack 80 having a larger amount as the stack on which the main player is placed.

Fig. 11 is a diagram showing a configuration of a game system 20 according to a second example of the embodiment of the present invention. The game system 20 of the second example is the game system 1 (see fig. 1) of the first example, and further includes: a player determination system 21 that determines a master player 3 m; a database 22 that stores information of the player 3 and the medal 8 in association; and an updating device 23 that stores information on the medals 8 of the stack 80 determined as the main player 3m in the database 22 in association with the player 3 determined as the main player 3 m.

According to the above configuration, at least the medal 8 of the main player 3m can be managed by the database 22. Further, the player determination system 21 may be a structure for determining the post-placement player 3 b.

The player determination system 21 includes an image recognition system 24 constituted by the camera 10 and an image recognition device, and a card authentication system 25 constituted by a card and a card reader, but may include any of them.

The camera 10 captures the face of the player 3, and outputs an image generated by the capturing to the image recognition apparatus. The image recognition device includes a face recognition engine of a neural network that learns face images of a plurality of players 3 (hereinafter, the registered players 3 are referred to as "members") registered in advance. The image recognition apparatus determines which member has been registered as the face image by inputting the image from the camera 10 to the neural network. When the image from the camera 10 is determined not to be the face of any member registered, the image recognition apparatus outputs the result that the face image is a non-member face image.

The camera 10 may capture images of a part other than the face of the player 3, and may be configured to associate information of clothing or physical features of the player 3 captured with information of the face of the player 3, for example.

The card reader scans the member delivered from the player 3 to the dealer and reads the information stored in the member card. The membership card is a magnetic card formed with a magnetic stripe storing at least a user ID of the player 3 (member). When a dealer stores a membership card for the player 3, the dealer scans the membership card using a card reader, and inputs to the card reader the position at which the player 3 plays a game (hereinafter referred to as "player position"). The card reader outputs the user ID read from the membership card and the area ID of the player position input by the dealer.

The information of the membership card may be associated with the player as the main player 3m or the post player 3 b.

In the player specifying system 21, only either one of the specification of the player 3 by the face authentication system and the specification of the player 3 by the reading of the membership card may be executed. That is, when the registered member is seated at the player position, the determination of the player 3 does not have to be made by the membership card, and in this case, the player 3 may be determined only by the face authentication system. Further, even in the case where the face of the player 3 cannot be clearly photographed and face authentication is not possible, the player 3 can be determined by the membership card. Further, the player 3 can be determined by either one of the face authentication and the membership card.

The information of the medal 8 may be value information, identification information, or other information of the medal 8. By grasping such information, it is possible to grasp which player 3 has received the payback of how many tokens 8, how many tokens 8 the dealer has collected, and further, how many tokens 8 each player 3 has held (holding amount) as a result of the payback or collection.

Although the game system described above is assumed to be used in a certain card game, the game system can be similarly used in other card games.
