The control information generator 22 is configured to generate control information INF for controlling the light emitting action of the light emitting unit 32 in the operation terminal 30 based on the detection result of the illuminance sensor 18. Then, the control unit 21 transmits the control information INF generated by the control information generator 22 to the operation terminal 30 via the wireless communication unit 13.

(operation terminal 30)

The operation terminal 30 is a so-called remote control terminal that controls the action of the display device 10 by remote operation based on the operation of the user. The operation terminal 30 includes an operation unit 31, a light-emitting unit 32, an acceleration sensor 33, an infrared transmitter 34, a wireless communication unit 35, a power supply unit 36, and a control unit 37.

The operation unit 31 is configured to accept an operation by a user. The operation unit 31 includes a plurality of buttons B. The control unit 37 causes the infrared transmitter 34 to transmit an infrared signal based on the user's operation of the plurality of buttons B.

Fig. 2 shows a configuration example of the operation terminal 30. A plurality of buttons B are provided on the operation surface S of the operation terminal 30. The plurality of buttons B include a power button B1, a moving picture service selection button B2, a number button B3, a color button B4, a voice assistant call button B5, a setting button B6, an input selection button B7, a cursor button B8, a determination button B9, a return button B10, a channel button B11, a volume button B12, a mute button B13, an audio selection button B14, a subtitle button B15, a moving picture content operation button B16, a record list button B17, a help button B18, and a data broadcast button B19.

The power button B1 is operated when the display device 10 is turned on or off. The moving image service selection button B2 is operated when the moving image streaming service is selected. In this example, the moving image service selection button B2 includes six buttons corresponding to six moving image streaming services (service S1 to service S6) different from each other. The number button B3 is operated when selecting a channel that the user wants to view or inputting a number. In this example, numeric button B3 includes 12 buttons. The color button B4 is operated when a selection operation is performed in, for example, data broadcast content or an electronic program guide. The voice assistant call button B5 is operated when calling a voice assistant. The setting button B6 is operated while a setting screen for setting the display device 10 is displayed. The input selection button B7 is operated when a video source to be displayed is selected from, for example, the tuner 11, an external device coupled to the external device interface 14, or the like. The cursor button B8 is operated when the cursor is moved in, for example, data broadcast contents or an electronic program guide. The determination button B9 is operated when a determination operation is performed. For example, the return button B10 is operated when returning to the previous menu. The channel button B11 is operated when a channel that the user wants to view is selected. The volume button B12 is operated when adjusting the volume. The mute button B13 is operated at the time of muting. For example, the audio selection button B14 is operated when audio is selected in the audio multiplex broadcast content. Specifically, the audio selection button B14 is operated when english or japanese is selected in multilingual content, and the audio selection button B14 is operated when main audio and sub audio are selected in content including the main audio and the sub audio, for example. The subtitle button B15 is operated when subtitle display is turned on or off in subtitle content. The moving image content operation button B16 is operated at the time of playing back the moving image content. In this example, the moving image content operation buttons B16 include a play button, a rewind button (rewind button), a fast forward button, a previous button, a next button, a stop button, and a pause button. In the case where, for example, a recording and playback device is coupled to the external device interface 14, the recording list button B17 is operated when a list of recorded contents is displayed. The help button B18 is operated when, for example, help information such as guidance on the operation method is displayed. The data broadcast button B19 is selected when data broadcast is displayed in the data broadcast content.

Therefore, the operation unit 31 includes a plurality of buttons B. The buttons B are configured to be highlighted by light emitted by the light emitting unit 32 disposed at the rear of the buttons B. Specifically, for example, the button B may be enabled to be highlighted by configuring the button B with a translucent material and transmitting light emitted from the light emitting unit 32 through the button B. Note that, without being limited to this, the button B may be enabled to be highlighted by configuring the button B with a material opaque to light and by light emitted from the light emitting unit 32 leaking from a gap around the button B, for example.

The light emitting unit 32 is configured to highlight the plurality of buttons B in the operation unit 31 by emitting light. The light emitting unit 32 includes a plurality of light emitting devices. For example, the light emitting operations of the plurality of light emitting devices can be controlled individually. The plurality of light emitting devices are disposed, for example, on the back of the plurality of buttons B. Specifically, the light-emitting unit 32 includes, for example, six light-emitting devices corresponding to respective six buttons included in the moving image service selection button B2. Therefore, the light emitting unit 32 can individually highlight the six buttons by the six light emitting devices individually emitting light. Further, for example, the light emitting unit 32 includes one light emitting device corresponding to 12 buttons included in the number button B3. Therefore, the 12 buttons can be collectively highlighted by the light emitting unit 32 by emitting light through the light emitting device.

The acceleration sensor 33 is configured to detect the movement of the operation terminal 30. Note that although the acceleration sensor 33 is provided in this example, the present disclosure is not limited thereto. The sensor may be any sensor capable of detecting the movement of the operation terminal 30. Specifically, for example, a gyro sensor may be provided.

The infrared transmitter 34 is configured to transmit an infrared signal giving an instruction of an action of the display device 10 to the infrared receiver 12 of the operation terminal 30.

The wireless communication unit 35 is configured to exchange information with the wireless communication unit 13 of the display device 10 by using short-range wireless communication. The wireless communication unit 35 receives control information INF for controlling the light emitting action of the light emitting unit 32 transmitted from the display device 10, as will be described later.

The power supply unit 36 is configured to supply a voltage supplied from a battery to, for example, a block in the operation terminal 30. The battery that supplies power to the power supply unit 36 may be a rechargeable battery. The rechargeable battery may be charged, for example, by using a wireless power supply such as Qi (registered trademark).

The control unit 37 is configured to control the action of the operation terminal 30 by controlling the action of the blocks of the operation terminal 30. In addition, the control unit 37 can shift the operation state of the operation terminal 30 to the sleep state or the normal operation state by controlling the operations of the blocks of the operation terminal 30. For example, in the sleep state, the power supply unit 36 stops supplying voltages to various blocks other than the operation unit 31, the acceleration sensor 33, and the control unit 37. The control unit 37 is configured by using, for example, a processor configured to execute a program. The control unit 37 includes a light emission controller 38. The light emission controller 38 is configured to control the light emission action of the light emitting unit 32 based on the control information INF transmitted from the display device 10.

With this configuration, in the display system 1, the control information generator 22 of the display device 10 generates the control information INF for controlling the light emitting action of the light emitting unit 32 in the operation terminal 30 based on the detection result of the illuminance sensor 18. Then, the wireless communication unit 13 of the display device 10 transmits the control information INF to the wireless communication unit 35 of the operation terminal 30. The light emission controller 38 of the operation terminal 30 controls the light emission operation of the light emitting unit 32 based on the control information INF. Therefore, in the display system 1, for example, in the case where the surroundings of the display device 10 are dark, the operation unit 31 can be highlighted by the light emitted from the light emitting unit 32. Therefore, the user can easily operate the operation terminal 30.

In this example, the operation terminal 30 does not include a network communication unit that can be coupled to the internet NET, and is configured to be able to transmit and receive information to and from an external device by using the infrared transmitter 34 or the wireless communication unit 35. Note that, without being limited thereto, the operation terminal 30 may include a network communication unit that is coupleable to the internet NET. In this case, the operation terminal 30 can use network communication, and thus can implement various functions. Further, the operation terminal may be implemented by using, for example, a smartphone or a tablet terminal.

[ actions and effects ]

Next, the action and action of the display system 1 according to the present embodiment will be described.

(overview of the overall action)

First, an overview of the overall action of the display system 1 will be described with reference to fig. 1. In the display device 10, a tuner 11 selects a desired video signal from broadcast waves received by the antenna 9. The infrared receiver 12 receives an infrared signal that is transmitted from the infrared transmitter 34 of the operation terminal 30 and gives an instruction of the action of the display device 10. The wireless communication unit 13 exchanges information with the wireless communication unit 35 of the operation terminal 30 by using short-range wireless communication. The external device interface 14 communicates with an external device. The network communication unit 15 receives video information from the plurality of content servers 201 through moving image streams. The display unit 16 displays video based on, for example, a video signal selected by the tuner 11. The speaker 17 emits sound based on, for example, a video signal selected by the tuner 11. The illuminance sensor 18 detects the brightness of the environment around the display device 10. The power supply unit 19 generates various power supply voltages based on, for example, a power supply signal supplied from a commercial power supply, and supplies the power supply voltages to blocks in the display device 10. The control unit 21 controls the action of the display device 10 by controlling the action of the blocks of the display device 10.

In the operation terminal 30, a plurality of buttons B of the operation unit 31 accept operations by the user. The light emitting unit 32 highlights the plurality of buttons B in the operation unit 31 by emitting light. The acceleration sensor 33 detects the movement of the operation terminal 30. The infrared transmitter 34 transmits an infrared signal giving an instruction of the action of the display device 10 to the infrared receiver 12 of the operation terminal 30. The wireless communication unit 35 exchanges information with the wireless communication unit 13 of the display device 10 by using short-range wireless communication. The power supply unit 36 supplies, for example, a voltage supplied from a battery to the blocks in the operation terminal 30. The control unit 37 controls the action of the operation terminal 30 by controlling the action of the blocks of the operation terminal 30.

The control information generator 22 of the display device 10 generates control information INF for controlling the light emitting action of the light emitting unit 32 in the operation terminal 30 based on the detection result of the illuminance sensor 18. The wireless communication unit 13 transmits the control information INF generated by the control information generator 22 to the operation terminal 30. The wireless communication unit 35 of the operation terminal 30 receives the control information INF transmitted from the display device 10. The light emission controller 38 controls the light emission operation of the light emitting unit 32 based on the control information INF.

(detailed actions)

Fig. 3 shows an example of the action of the operation terminal 30. In the case where the motion is detected, or in the case where the user operation to the operation unit 31 is detected, the operation terminal 30 issues a transmission request of the control information INF to the display device 10. Then, the operation terminal 30 controls the light emitting action of the light emitting unit 32 based on the control information INF transmitted from the display device 10. This action is described in detail below.

First, the control unit 37 checks whether the movement of the operation terminal 30 has been detected based on the detection result of the acceleration sensor 33 (step S101). For example, in a case where the user lifts up the operation terminal 30 placed on a table, the control unit 37 detects the movement of the operation terminal 30.

If the movement of the operation terminal 30 is not detected in step S101 (no in step S101), the control unit 37 checks whether or not the user operation to the operation unit 31 has been detected (step S102). For example, in a case where the user operates the button B of the operation terminal 30 placed on a desk, the control unit 37 detects the user operation to the operation unit 31. If the user operation to the operation unit 31 is not detected (no in step S102), the flow returns to step S101, and the control unit 37 repeats steps S101 and S102 until the movement of the operation terminal 30 is detected or the user operation to the operation unit 31 is detected.

Here, the control unit 37 of the manipulation terminal 30 may control the acceleration sensor 33 to detect the movement of the manipulation terminal 30 at predetermined intervals. Further, upon detection of the movement of the operation terminal 30 or the user operation on the operation unit 31, the control unit 37 may detect the movement of the operation terminal 30 at an interval different from the interval before the detection of the movement or the user operation. For example, as shown in fig. 4, the control unit 37 can normally detect acceleration (movement of the operation terminal 30) at a detection interval T of 500 ms. Further, in a case where the control unit 37 detects a motion of the operation terminal 30 or a user operation on the operation unit 31, the control unit 37 may detect acceleration at a detection interval T of 100 ms. Then, after the light emission controller 38 causes the light emitting unit 32 to emit light and ends the light emission, the detection interval T may return to 500ms after a predetermined period of time (e.g., 30 seconds) has elapsed. Therefore, for example, it is possible to suppress a delay until the light emitting unit 32 emits light after the user lifts up the operation terminal 30.

If the movement of the operation terminal 30 has been detected in step S101 (yes in step S101), or if the user operation on the operation unit 31 has been detected in step S102 (yes in step S102), the control unit 37 changes the action state of the operation terminal 30 from the sleep state to the normal action state (step S103).

Next, the control unit 37 issues a transmission request of the control information INF to the display device 10 via the wireless communication unit 35 (step S104). In this example, the control information INF includes sensor information INF1 indicating the detection result of the illuminance sensor 18. Then, the control unit 37 receives the control information INF transmitted from the display device 10 via the wireless communication unit 35 in response to the transmission request.

Next, the light emission controller 38 of the control unit 37 checks whether the luminance of the environment indicated by the sensor information INF1 included in the control information INF is darker than a predetermined luminance (step S105). If the luminance of the environment is brighter than the predetermined luminance (no in step S105), the flow ends. That is, in the case where the brightness of the environment is brighter than the predetermined brightness, the user can easily visually recognize the button B of the operation unit 31 of the operation terminal 30. Therefore, the flow ends in a case where the light emission controller 38 does not cause the light emitting unit 32 to emit light.

If the luminance of the environment indicated by the sensor information INF1 is darker than the predetermined luminance in step S105 (yes in step S105), the light emission controller 38 generates light emission control information INFBL giving an instruction of the light emission action of the light emitting unit 32 based on the sensor information INF1 (step S106). The light emission control information INFBL includes, for example, information on the light emission start, the light emission end, the light emission luminance, the light emission time, the light emission period, and the like of each light emitting device of the light emitting unit 32.

Then, the light emission controller 38 controls the light emission operation of the light emitting unit 32 based on the light emission control information INFBL (step S107). Accordingly, the operation unit 31 of the operation terminal 30 is highlighted by the light emitted from the light emitting unit 32.

The flow ends here.

Fig. 5 shows an action example of the display system 1 in a case where the user lifts up the operation terminal 30 placed on the desk in a dark environment.

When the user lifts up the operation terminal 30, the control unit 37 of the operation terminal 30 detects the movement of the operation terminal 30, and changes the operation state of the operation terminal 30 from the sleep state to the normal operation state (step S121). Then, the control unit 37 issues a transmission request of the control information INF including the sensor information INF1 to the display device 10 via the wireless communication unit 35 (step S122). The control unit 21 of the display device 10 receives the transmission request via the wireless communication unit 13.

The control information generator 22 of the display device 10 acquires the detection result of the illuminance sensor 18 as the sensor information INF1 in response to the transmission request (step S123). In this example, the sensor information INF1 includes information about the brightness of the environment darker than a predetermined brightness. Then, the control unit 21 transmits the control information INF including the sensor information INF1 to the operation terminal 30 via the wireless communication unit 13 (step S124). The control unit 37 of the operation terminal 30 receives the control information INF via the wireless communication unit 35.

The light emission controller 38 of the operation terminal 30 generates light emission control information INFBL based on the sensor information INF1 included in the control information INF (step S125). That is, in this example, since the luminance of the environment is darker than the predetermined luminance, the light emission controller 38 generates the light emission control information INFBL based on the sensor information INF 1. In this example, the light emission control information INFBL is information giving an instruction to cause all the light emitting devices in the light emitting unit 32 to emit light for a predetermined period of time.

Next, the light emission controller 38 starts light emission of the light emitting unit 32 based on the light emission control information INFBL (step S126). Accordingly, the operation unit 31 of the operation terminal 30 is highlighted by the light emitted from the light emitting unit 32. Then, the light emission controller 38 causes the light emitting unit 32 to end light emission after a predetermined period of time has elapsed based on the light emission control information INFBL (step S127).

The sequence ends here.

The light emission controller 38 may perform control to change the light emission method of the light emission unit 32 at the light emission start, the light emission end, or both the light emission start and the light emission end of the light emission unit 32. For example, the light-emitting unit 32 may gradually change the luminance from the current luminance to the target luminance at the start of light emission and the end of light emission, and emit light at a constant luminance after reaching the target luminance. Further, the length of the period in which the luminance gradually changes and the length of the period in which the constant luminance is maintained may be predetermined periods, respectively, or may be dynamically changed according to the use state of the operation terminal 30. Fig. 6A to 6H illustrate an example of a light emitting method of the light emitting unit 32.

(case C1, case where the pressing time TP of the button B is short)

In the example of fig. 6A, in a case where the user operates the operation unit 31, the luminance of the light emitting unit 32 is gradually changed at the start of light emission and the end of light emission. In this example, the user presses button B. The time from the start of light emission to the end of light emission is set to 3 seconds, and the light emission time at the target luminance is set to 1 second. Specifically, the luminance of the light emitting unit 32 gradually rises from the start of light emission, reaches the target luminance 1 second later, maintains the constant luminance for 1 second, and then gradually falls to 0 (zero) 1 second later. For example, in the case where the pressing time TP of the button B is sufficiently short (for example, 1 second or less), the light emitting unit 32 emits light for 3 seconds from the start of light emission to the end of light emission (off), as described above.

(case C2, case where the pressing time TP of button B is long)

In the example of fig. 6B, as in the case of fig. 6A, the time from the start of light emission to the end of light emission is set to 3 seconds. In this case, the user presses the button B for a longer time than in the case of fig. 6A. If the pressing time TP of the button B exceeds 1 second, the luminance of the light emitting unit 32 gradually rises to the target luminance within 1 second while the user presses the button B, and then is maintained at a constant luminance. Then, the luminance of the light emitting unit 32 is maintained at a constant luminance until 1 second elapses after the user finishes pressing the button B. After 1 second has elapsed after the user has finished pressing the button B, the luminance of the light emitting unit 32 gradually decreases to become 0 (zero) after 1 second.

(case C3, case where the pressing time TP of the button B exceeds a predetermined period of time)

In the example shown in fig. 6C, as in the case of fig. 6A, the time from the start of light emission to the end of light emission is set to 3 seconds. In this case, the user presses the button B for a longer time than in the case of fig. 6B. In a case where the pressing time TP of the button B exceeds 1 second and further exceeds a predetermined period of time (e.g., 60 seconds), the luminance of the light emitting unit 32 gradually rises to the target luminance within 1 second while the user presses the button B, and then is kept at the constant luminance until the predetermined period of time (e.g., 60 seconds) elapses. After the predetermined period of time has elapsed, the luminance of the light emitting unit 32 gradually decreases to become 0 (zero) after 1 second.

(case C4, case where button B is pressed during the course of ending light emission)

In the example of fig. 6D, in the case where the time from the start of light emission to the end of light emission is set to 3 seconds, as in the case of fig. 6A, the user presses the button B again in the course of ending the light emission. In this case, the luminance of the light emitting unit 32 gradually rises from the luminance when the user presses the button B again to the target luminance. The time from the timing of pressing the button B to the time when the luminance reaches the target luminance may be the same as the time from the start of the light emission end action to the pressing of the button B. The luminance of the light emitting unit 32 is maintained for 1 second after reaching the target luminance again, and then gradually decreases to become 0 (zero) after 1 second. This example describes a case where the user presses the button B again in the course of ending the lighting. In the case where the user presses the button B again while the light-emitting unit 32 maintains the target luminance, the light-emitting unit 32 may shift to the light-emission end action after 1 second has elapsed from the timing at which the user presses the button B again.

(case C5, in the case of detecting acceleration while the luminance is rising)

In the example of fig. 6E, as in the case of fig. 6A, the time from the start of light emission to the end of light emission is set to 3 seconds. In this example, when light emission starts, the user performs a user operation by moving the operation terminal 30. Therefore, in the case where the acceleration corresponding to the user operation is detected only in the period (1 second in this example) in which the luminance of the light-emitting unit 32 increases, the light-emitting unit 32 emits light for 3 seconds from the start of light emission to the end (off) of light emission, as in the case of fig. 6A.

(case C6, case where acceleration is detected while luminance is maintained.)

In the example of fig. 6F, in the case where the time from the start of light emission to the end of light emission is set to 3 seconds, as in the case of fig. 6E, the acceleration corresponding to the user operation is further detected in the period in which 1 second has elapsed from the start of light emission and the light-emitting unit 32 holds the target luminance. In this case, after 1 second has elapsed from the timing at which the acceleration is detected in the period in which the target luminance is maintained, the luminance of the light emitting unit 32 gradually decreases to become 0 (zero) after 1 second.

(case C7, case where acceleration is detected during the light emission is ended)

In the example of fig. 6G, in the case where the time from the start of light emission to the end of light emission is set to 3 seconds, as in the case of fig. 6E, the acceleration corresponding to the user operation is further detected in the course of ending the light emission. In this case, the luminance of the light emitting unit 32 gradually rises from the luminance at the timing at which the acceleration is first detected in the process of ending the light emission to the target luminance. The time from the timing at which the acceleration is detected for the first time to the time at which the luminance reaches the target luminance may be the same as the time from the start of the light emission end action to the time at which the acceleration is detected for the first time.

(case C8, acceleration detected when button B is pressed)

In the example of fig. 6H, in the case where the time from the light emission start to the light emission end is set to 3 seconds, as in the case of fig. 6A, the light emitting unit 32 performs light emission corresponding to the detection of acceleration after light emission corresponding to the pressing of the button B. Here, as in the example of fig. 6C, the user first presses the button B for more than a predetermined period of time (e.g., 60 seconds). Therefore, the light emitting unit 32 performs a light emitting process corresponding to the pressing of the button B for a total of 61 seconds, and then sets the luminance to 0. Thereafter, in a case where the acceleration caused by the user moving the operation terminal 30 is detected, the light emitting unit 32 performs the light emitting process again. Note that, as shown in fig. 4, in some embodiments, the detection interval T of the acceleration sensor 33 is shorter than usual until a predetermined period of time (for example, 30 seconds) has elapsed from the pressing of the button B or the detection of the acceleration. Therefore, in the case where the light emission corresponding to the detection of the acceleration is performed within a predetermined period of time from the light emission corresponding to the pressing of the button B, the response time until the light emission unit 32 emits light after the user moves the operation terminal 30 is short.

Although examples of the light emission control in the case C1 to the case C8 have been described by using fig. 6A to 6H, the above light emission control is an example, and the present disclosure is not limited to these examples. For example, in the example of the case C1, the time from the start of light emission to the change in target luminance, the time to hold the target luminance, and the time taken to end the light emission are 1 second, respectively. Not limited thereto, for example, may be shorter than 1 second, or may be longer than 1 second. Further, the luminance of the light emitting unit 32 is made to gradually change at both the start of light emission and the end of light emission, but is not limited thereto. For example, the luminance of the light emitting unit 32 may be gradually changed only at any one of the light emission start and the light emission end. Further, for example, the luminance of the light emitting unit 32 may be made not to gradually change at both the start of light emission and the end of light emission. In this case, the luminance of the light emitting unit 32 becomes the target luminance (constant luminance state or luminance 0 state) in a short time. Further, only in the case where the pressing of the button B is detected or the acceleration is detected in the course of ending the light emission, the luminance of the light emitting unit 32 may be made to become the target luminance in a short time, instead of being gradually changed.

As described above, in the display system 1, the control information generator 22 of the display device 10 adjusts the display luminance of the display unit 16 using the illuminance sensor 18 to generate the control information INF corresponding to the detection result of the illuminance sensor 18. The light emission controller 38 of the operation terminal 30 controls the light emission operation of the light emitting unit 32 based on the control information INF. Therefore, in the display system 1, for example, in the case where the surroundings of the display device 10 are dark, the operation unit 31 can be highlighted by the light from the light emitting unit 32, which enables the user to easily operate the operation terminal 30. Therefore, the display system 1 can improve the convenience of the user.

In the display system 1, when the ambient brightness is lower than the predetermined brightness, the light emitting operation of the light emitting unit 32 is controlled. Therefore, the light emitting unit 32 does not need to emit light in a case where the surroundings of the display device 10 are bright, which makes it possible to reduce power consumption. Therefore, in the display system 1, it is possible to reduce, for example, the number of times the battery used in the operation terminal 30 is replaced and the number of times the battery is charged. This makes it possible to improve the convenience of the user.

In the display system 1, the light emitting operation of the light emitting unit 32 is controlled based on the control information INF. Therefore, for example, after a predetermined period of time has elapsed after the light emitting unit 32 is caused to start emitting light, the light emitting unit 32 may be caused to end emitting light. This makes it possible to limit the light emission time of the light emitting unit 32, which makes it possible to reduce power consumption. Therefore, in the display system 1, it is possible to reduce, for example, the number of times the battery used in the operation terminal 30 is replaced and the number of times the battery is charged. This makes it possible to improve the convenience of the user.

Further, the display system 1 adjusts the display luminance of the display unit 16 using the illuminance sensor 18 provided in the display device 10. Therefore, it is not necessary to provide an illuminance sensor in the operation terminal 30, which makes it possible to reduce the number of components of the operation terminal 30. Therefore, in the display system 1, for example, the cost of the operation terminal 30 can be reduced.

[ Effect ]

As described above, in the present embodiment, the control information generator of the display device generates control information corresponding to the detection result of the illuminance sensor. A light emission controller of the operation terminal controls a light emission operation of the light emission unit based on the control information. Therefore, for example, in the case where the surroundings of the display device are dark, the operation unit can be highlighted by the light from the light emitting unit, which makes it possible to improve the convenience of the user.

In this embodiment, when the luminance of the environment is darker than a predetermined luminance, the light emitting operation of the light emitting unit is controlled. This makes it possible to reduce, for example, the number of times the battery used in the operation terminal is replaced and the number of times the battery is charged. This makes it possible to improve the convenience of the user.

In the present embodiment, the light emitting operation of the light emitting unit is controlled based on the control information. Thus, for example, after a predetermined period of time has elapsed after the start of light emission by the light-emitting unit, the light emission by the light-emitting unit may be ended. This makes it possible to reduce, for example, the number of times the battery used in the operation terminal is replaced and the number of times the battery is charged. This makes it possible to improve the convenience of the user.

The present embodiment adjusts the display luminance of the display unit using an illuminance sensor provided in the display apparatus. This makes it possible to reduce the cost of operating the terminal.

[ modified example 1-1]

In the above-described embodiment, the control information INF includes the sensor information INF 1. Without being limited thereto, the control information INF may include various information for controlling the light emitting action of the light emitting unit 32 in the operation terminal 30. The following is a detailed description of an example in which the control information INF includes light emission control information INFBL giving an instruction of the light emission action of the light emitting unit 32.

As in the case of the above-described embodiment (fig. 1), the display system 1A according to the present modified example includes the display device 10A and the operation terminal 30A. The display device 10A includes a control unit 21A. The control unit 21A includes a control information generator 22A. The control information generator 22A is configured to generate control information INF including light emission control information INFBL based on the detection result of the illuminance sensor 18. The operation terminal 30A includes a control unit 37A. The control unit 37A includes a light emission controller 38A. The light emission controller 38A is configured to control the light emission action of the light emitting unit 32 based on control information INF including light emission control information INFBL.

Fig. 7 shows an action example of the operation terminal 30A.

First, the control unit 37A checks whether the motion of the operation terminal 30A has been detected based on the detection result of the acceleration sensor 33 (step S101). If the movement of the operation terminal 30A is not detected (no in step S101), the control unit 37A checks whether or not the user operation to the operation unit 31 has been detected (step S102). If the user operation to the operation unit 31 is not detected (no in step S102), the flow returns to step S101.

If the movement of the operation terminal 30A has been detected in step S101 (yes in step S101), or if the user operation on the operation unit 31 has been detected in step S102 (yes in step S102), the control unit 37A changes the action state of the operation terminal 30A from the sleep state to the normal action state (step S103).

Next, the control unit 37A issues a transmission request of the control information INF to the display device 10A via the wireless communication unit 35 (step S134). In this example, the control information INF includes light emission control information INFBL giving an instruction of a light emission action of the light emitting unit 32. Then, the control unit 37A receives the control information INF transmitted from the display device 10A via the wireless communication unit 35 in response to the transmission request.

Next, the light emission controller 38A of the control unit 37A controls the light emission operation of the light emitting unit 32 based on the light emission control information INFBL included in the control information INF (step S137). Thus, the operation unit 31 of the operation terminal 30A is highlighted by the light emitted from the light emitting unit 32. The flow ends here.

Fig. 8 shows an action example of the display device 10A.

First, the display device 10A checks whether a transmission request of the control information INF including the light emission control information INFBL has been received from the operation terminal 30A (step S141). If the transmission request of the control information INF has been received (yes in step S141), the control information generator 22A of the control unit 21A acquires the detection result of the illuminance sensor 18 as the sensor information INF1 (step S142).

Next, the control information generator 22A checks whether the brightness of the environment indicated by the sensor information INF1 is darker than a predetermined brightness (step S143). If the brightness of the environment is darker than the predetermined brightness (yes in step S143), the control information generator 22A generates light emission control information INFBL including an instruction to cause the light emitting unit 32 to emit light based on the sensor information INF1 (step S144). Further, if the luminance of the environment is brighter than the predetermined luminance (no in step S143), the control information generator 22A generates light emission control information INFBL including an instruction not to cause the light emitting unit 32 to emit light based on the sensor information INF1 (step S145).

Then, the control unit 21A transmits control information INF including light emission control information INFBL to the operation terminal 30A via the wireless communication unit 13 (step S146). The flow ends here.

Fig. 9 shows an action example of the display system 1A in a case where the user operates the operation unit 31 of the operation terminal 30A placed on the desk in a dark environment.

When the user operates the operation unit 31 of the operation terminal 30A, the control unit 37A of the operation terminal 30A detects the user operation and changes the operation state of the operation terminal 30A from the sleep state to the normal operation state (step S151). Then, the control unit 37A issues a transmission request of the control information INF including the light emission control information INFBL to the display device 10A via the wireless communication unit 35 (step S152). The wireless communication unit 13 of the display device 10A receives the transmission request.

The control information generator 22A of the display device 10A acquires the detection result of the illuminance sensor 18 as the sensor information INF1 in response to the transmission request (step S153). In this example, the sensor information INF1 includes information about the brightness of the environment darker than a predetermined brightness. Then, the control information generator 22A generates the light emission control information INFBL based on the sensor information INF1 (step S154). In this example, since the luminance of the environment is darker than the predetermined luminance, the control information generator 22A generates the light emission control information INFBL giving an instruction to cause all the light emitting devices in the light emitting unit 32 to emit light for a predetermined period of time based on the sensor information INF 1. Then, the control unit 21A transmits control information INF including light emission control information INFBL to the operation terminal 30A via the wireless communication unit 13 (step S155). The control unit 37A of the operation terminal 30A receives the control information INF via the wireless communication unit 35.

Next, the light-emission controller 38A of the operation terminal 30A causes the light-emitting unit 32 to start light emission based on the light-emission control information INFBL included in the control information INF (step S126). Thus, the operation unit 31 of the operation terminal 30A is highlighted by the light emitted from the light emitting unit 32. Then, the light emission controller 38A causes the light emitting unit 32 to end light emission after a predetermined period of time has elapsed based on the light emission control information INFBL (step S127). The sequence ends here.

[ modified examples 1-2]

In the above-described embodiment, the light emission controller 38 generates the light emission control information INFBL giving an instruction to cause all the light emitting devices in the light emitting unit 32 to emit light in the case where the luminance of the environment indicated by the sensor information INF1 is darker than the predetermined luminance, but is not limited thereto. Alternatively, for example, the light emission controller 38 may generate the light emission control information INFBL giving an instruction to cause all the light emitting devices in the light emitting unit 32 to emit light at a higher light emission luminance the darker the brightness of the environment indicated by the sensor information INF 1.

[ modified examples 1 to 3]

In the above-described embodiment, the control information generator 22 generates the control information INF based on the brightness of the environment detected by the illuminance sensor 18, but is not limited thereto. The control information generator may also generate the control information INF based on other parameters about the environment. The following is a detailed description of the present modified example with reference to some examples.

Fig. 10 shows a configuration example of a display system 1B according to the present modified example. The display system 1B includes a display device 10B and an operation terminal 30B.

The display device 10B includes a color sensor 18B and a control unit 21B.

The color sensor 18B is configured to detect the color of the environment around the display device 10. Specifically, the color sensor 18B is capable of detecting, for example, the color of illumination of a room in which the display device 10B is provided. The control unit 21B adjusts the display color on the display unit 16 based on the detection result of the color sensor 18B. Here, the illuminance sensor 18 and the color sensor 18B correspond to a specific example of the "environment sensor" according to the present disclosure.

The control unit 21B includes a control information generator 22B. The control information generator 22B is configured to generate the control information INF based on the detection result of the illuminance sensor 18 and the detection result of the color sensor 18B. That is, the control information generator 22B generates the control information INF based on the brightness of the environment and the color of the environment.

The operation terminal 30B includes a light-emitting unit 32B and a control unit 37B.

The light emitting unit 32B is configured to highlight the plurality of buttons B in the operation unit 31 by emitting light. The light emitting unit 32B includes, for example, a plurality of light emitting devices. The plurality of light emitting devices include, for example, a light emitting device that emits red light, a light emitting device that emits green light, and a light emitting device that emits blue light.

The control unit 37B includes a light emission controller 38B. The light emission controller 38B is configured to control the light emission action of the light emitting unit 32B based on the control information INF transmitted from the display device 10B. Specifically, for example, in the case where the color of illumination of the room in which the display device 10B is set is natural white, the light emission controller 38B generates the instruction light emission control information INFBL giving an instruction to cause the light emitting means to emit light to cause the light emitting unit 32B to emit white light. Further, for example, in the case where the color of illumination of the room in which the display apparatus 10B is set is warm white, the light emission controller 38B generates the light emission control information INFBL giving an instruction to cause the light emitting device to emit light to cause the light emitting unit 32B to emit warm color light. That is, in this example, the light emission control information INFBL further includes information on the light emission color of the light emitting unit 32B.

This configuration enables the display system 1B to control the light emitting action of the light emitting unit 32B based on the information on the luminance of the environment obtained by the illuminance sensor 18 and the information on the color of the environment obtained by the color sensor 18B.

Fig. 11 shows a configuration example of another display system 1C according to the present modified example. The display system 1C includes a display device 10C and an operation terminal 30B. The display device 10C includes a camera 18C and a control unit 21C.

The camera 18C is configured to generate a captured image by imaging the user in front of the display device 10C. The display device 10C can realize a function of, for example, a videophone using the captured image. The captured image includes information about the brightness of the environment and the color of the environment. Here, the camera 18C corresponds to a specific example of the "environment sensor" according to the present disclosure.

The control unit 21C includes a control information generator 22C. The control information generator 22C is configured to generate the control information INF based on the captured image obtained by the camera 18C. That is, the control information generator 22B related to the display device 10B (fig. 10) generates the control information INF based on the information on the luminance of the environment obtained by the illuminance sensor 18 and the information on the color of the environment obtained by the color sensor 18B. In contrast, the control information generator 22C generates the control information INF based on the information on the brightness of the environment and the color of the environment obtained by the camera 18C.

This configuration enables the display system 1C to control the light emitting action of the light emitting unit 32B based on the information on the brightness of the environment and the color of the environment obtained by the camera 18C.

[ modified examples 1 to 4]

In the above-described embodiment, as shown in fig. 2, the operation terminal 30 includes a plurality of buttons B, but is not limited thereto. Alternatively, for example, a display unit 39D may be included in addition to the plurality of buttons B, as in the operation terminal 30D shown in fig. 12. The display unit 39D is configured by using, for example, a liquid crystal display, an organic EL display, or the like. In this case, the light emitting unit 32 may highlight the plurality of buttons B by emitting light, as in the case of the above-described embodiment. The light emission controller 38D according to the present modified example can control the light emission action of the light emission unit 32 based on the control information INF and also control the display action of the display unit 39D. Specifically, the light emission controller 38D may, for example, cause the light emitting unit 32 to emit light and cause the display unit 39D to display information based on the control information INF.

Further, for example, the operation terminal may include a touch panel in addition to the display unit. In this case, the user can perform an operation by touching the button image displayed on the display unit. The light emission controller can control the display operation of the display unit based on the control information INF to cause the display unit to display the highlighted button image. For example, a smart phone may be used as the operation terminal.

[ modified examples 1 to 5]

In the above-described embodiment, the illuminance sensor 18 is provided in the display device 10. Without being limited thereto, the illuminance sensor may be provided in the operation terminal 30. Then, the light emission controller 38 of the operation terminal 30 may control the light emission operation of the light emitting unit 32 based on the detection result of the illuminance sensor 18 of the display device 10 and the detection result of the illuminance sensor of the operation terminal 30. Further, in the case where the use of the illuminance sensor provided in the operation terminal 30 instead of the illuminance sensor 18 provided in the display device 10 makes it possible to control the light emitting action, the light emission controller 38 may control the light emitting action by using only the detection result of the illuminance sensor in the operation terminal 30. In this case, the illuminance sensor 18 may not be provided in the display apparatus 10.

Similarly, in the display system 1B according to modified examples 1 to 3 (fig. 10), for example, the illuminance sensor 18 and the color sensor 18B are provided in the display device 10B. Without being limited thereto, an illuminance sensor and a color sensor may be provided in the operation terminal 30B. Then, the light emission controller 38B may control the light emission action of the light emission unit 32 based on the detection results of the illuminance sensor 18 and the color sensor 18B of the display device 10B and the detection results of the illuminance sensor and the color sensor of the operation terminal 30. Further, in the case where using one or both of the illuminance sensor and the color sensor provided in the operation terminal 30B instead of using one or both of the illuminance sensor 18 and the color sensor 18B provided in the display device 10B makes it possible to control the light emitting action, the light emission controller 38B can control the light emitting action by using only the detection result of the sensor in the operation terminal 30B. In this case, one or both of the illuminance sensor 18 and the color sensor 18B may not be provided in the display device 10B.

Further, the control unit 21B of the display device 10B may control the action of the display device 10B by receiving, from the operation terminal 30B, environment information (for example, the brightness of the environment or the color of the environment) acquired by one or both of the illuminance sensor and the color sensor provided on the operation terminal 30B. Specifically, for example, the control unit 21B may adjust the display luminance of the display unit 16 based on information related to the luminance of the environment and acquired by the illuminance sensor of the operation terminal 30B. Further, for example, the control unit 21B may adjust the display contrast of the display unit 16 based on information related to the color of the environment and acquired by the color sensor of the operation terminal 30B. Thus, using the information of the environment sensor provided in the operation terminal 30B makes it possible to acquire the environment information that enables the influence due to the reflection of the light emitted from the display unit 16 of the display device 10B to be reduced. Note that the control of the display device 10B based on the environment sensor of the operation terminal 30B is not limited to the control of the display unit 16, and any setting of the display device 10B may be changed. Further, the sensor information transmitted from the environment sensor of the operation terminal 30B to the display device 10B may be information corresponding to the sensor information INF1 or the control information INF.

Further, in a case where an environment sensor such as an illuminance sensor or a color sensor is provided in the operation terminal 30B, the power supply unit 36 may supply the power supply voltage to the environment sensor of the operation terminal 30B only for a short period of time corresponding to the detection timing, based on the detection of the motion of the operation terminal 30B or the detection of the user operation of the operation unit 31. In addition, in the case where the operation terminal 30B transmits the infrared signal, the transmission timing of the infrared signal and the timing of the illuminance detection process may be offset from each other to reduce the influence of the fluctuation of the infrared signal and the power supply voltage on the illuminance sensor of the operation terminal 30B. Specifically, for example, when the user presses the button B of the operation unit 31, the control unit 37B may detect information related to the brightness of the environment by using the illuminance sensor, and after the detection process of the illuminance sensor ends, may control the infrared transmitter 34 to transmit an infrared signal corresponding to the button B to the device to be operated (such as the display device 10B).

In addition, the control unit 21B can operate the display device 10B by using the detection results of the acceleration sensor 33 and the environment sensor of the operation terminal 30B. Specifically, for example, in a case where it is determined that the operation terminal 30 is turned over based on the detection result of the illuminance sensor or the acceleration sensor 33 of the operation terminal 30B, the control unit 21B may stop supplying the power supply voltage to the display unit 16, or may turn off the power supply of the display device 10B. In this case, the display device 10B may receive, for example, sensor information indicating that the operation surface S provided with the operation unit 31 and the illuminance sensor is directed downward in the vertical direction from the operation terminal 30B.

In addition, two or more of these modified examples may be combined with each other.

<2 > second embodiment

Next, a description will be given about the display system 2 according to the second embodiment. The display system 2 according to the present embodiment is configured to control the light emitting action of the light emitting unit of the operation terminal according to the content displayed by the display device. Note that substantially the same components as those of the display system 1 according to the first embodiment are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

Fig. 13 shows a configuration example of the display system 2. The display system 2 includes a display device 40 and an operation terminal 50.

The display device 40 includes a control unit 41. The control unit 41 includes a content analyzer 43 and a control information generator 42.

The content analyzer 43 is configured to analyze content displayed by the display unit 16 of the display device 40. Specifically, in the case where the display unit 16 displays a video based on, for example, a video signal selected by the tuner 11, the content analyzer 43 analyzes the content by analyzing broadcast metadata included in the video signal.

The control information generator 42 is configured to generate control information INF for controlling the light emitting action of the light emitting unit 32 in the operation terminal 50 based on the analysis result of the content analyzer 43. Then, the display device 40 transmits the control information INF generated by the control information generator 42 to the operation terminal 50 via the wireless communication unit 13.

The operation terminal 50 includes a control unit 57. The control unit 57 includes a light emission controller 58. The light emission controller 58 is configured to control the light emission action of the light emitting unit 32 based on the control information INF transmitted from the display device 40.

Fig. 14 shows an action example of the display device 40.

First, the control unit 41 checks whether the infrared receiver 12 has received the infrared signal transmitted from the operation terminal 50 (step S201).

If the infrared receiver 12 has received the infrared signal (yes in step S201), the control unit 41 checks whether the user has performed a channel changing operation (step S202). Specifically, the control unit 41 checks whether the user has performed a channel change operation by, for example, checking whether the infrared signal is a signal corresponding to an operation on the numeric button B3 or the channel button B11 shown in fig. 2.

If the user has performed a channel change operation in step S202 (yes in step S202), the content analyzer 43 checks whether the content being displayed is audio multiplex broadcast content based on the broadcast metadata included in the video signal corresponding to the channel newly selected by the channel change operation (step S203). Examples of audio multiplex broadcast content include multilingual content and content including main audio and sub audio. If the content being displayed is the audio multiplex broadcast content (yes in step S203), the control information generator 42 generates the content information INF2 including information indicating that the content being displayed is the audio multiplex broadcast content (step S204).

Next, the content analyzer 43 checks whether the content being displayed is subtitle content based on the broadcast metadata (step S205). If the content being displayed is subtitle content (yes in step S205), the control information generator 42 generates content information INF2 including information indicating that the content being displayed is subtitle content (step S206).

Next, the content analyzer 43 checks whether the content being displayed is a data broadcast content based on the broadcast metadata (step S207). If the content being displayed is a data broadcast content (yes in step S207), the control information generator 42 generates content information INF2 including information indicating that the content being displayed is a data broadcast content (step S208). Then, the flow proceeds to step S211.

If the user does not perform the channel change operation in step S202 (no in step S201), the control unit 41 checks whether the user has performed an operation of selecting the moving image streaming service (step S209). Specifically, the control unit 41 checks whether the user has performed an operation of selecting the moving image streaming service by, for example, checking whether the infrared signal is a signal corresponding to an operation of the moving image service selection button B2 shown in fig. 2. If the user has not performed an operation of selecting the moving image streaming service (no in step S209), the flow ends.

If the user has performed an operation of selecting the moving image streaming service in step S209 (yes in step S209), the control information generator 42 generates the content information INF2 including information indicating that the content being displayed is the content provided by the moving image streaming service (step S210). Then, the flow proceeds to step S211.

Then, in a case where the control information generator 42 has generated the content information INF2, the control unit 41 transmits the control information INF including the content information INF2 to the operation terminal 50 via the wireless communication unit 13 (step S211). The flow ends here.

Fig. 15 shows an action example of the display system 2 in a case where the user performs a channel change operation.

When the user performs a channel changing operation by, for example, operating the numeric button B3 or the channel button B11 of the operation terminal 50, the control unit 57 of the operation terminal 50 detects the operation and changes the action state of the operation terminal 50 from the sleep state to the normal action state (step S221). Then, the infrared transmitter 34 transmits an infrared signal corresponding to the channel changing operation (step S222). The infrared receiver 12 of the display device 40 receives the infrared signal.

The tuner 11 of the display device 40 switches the channel based on the information about the channel changing operation included in the infrared signal (step S223). Then, the content analyzer 43 analyzes the content by analyzing the broadcast metadata included in the video signal selected by the tuner 11 (step S224). The control information generator 42 generates the content information INF2 based on the analysis result of the content analyzer 43 (step S225). Then, the control unit 41 transmits the control information INF including the content information INF2 to the operation terminal 50 via the wireless communication unit 13 (step S226). The control unit 57 of the operation terminal 50 receives the control information INF via the wireless communication unit 35.

The light emission controller 58 of the operation terminal 50 generates light emission control information INFBL based on the content information INF2 included in the control information INF (step S227).

For example, in the case where the content information INF2 includes information indicating that the content being displayed is audio multiplex broadcast content, the light emission controller 58 generates light emission control information INFBL giving an instruction to cause the light emitting device corresponding to the audio selection button B14 (fig. 2) in the light emitting unit 32 to emit light for a predetermined period of time.

Further, for example, in the case where the content information INF2 includes information indicating that the content being displayed is subtitle content, the light-emission controller 58 generates light-emission control information INFBL giving an instruction to cause the light-emitting device corresponding to the subtitle button B15 (fig. 2) in the light-emitting unit 32 to emit light for a predetermined period of time.

Further, for example, in a case where the content information INF2 includes information indicating that the content being displayed is data broadcast content, the light emission controller 58 generates light emission control information INFBL giving an instruction to cause the light emitting devices corresponding to the data broadcast button B19, the color button B4, and the digital button B3 (fig. 2) in the light emitting unit 32 to emit light for a predetermined period of time. Note that the present disclosure is not limited thereto. For example, in a case where the content being displayed is data broadcast content and the content does not accept the operation of the color button B4 and the numeric button B3, the light-emission controller 58 may generate the light-emission control information INFBL giving an instruction to cause the light-emitting device corresponding to the data broadcast button B19 to emit light for a predetermined period of time. Further, for example, in a case where the content being displayed is data broadcast content and the content accepts operations to the color button B4 and the digital button B3, the light emission controller 58 may generate the light emission control information INFBL giving an instruction to cause the light emitting devices corresponding to the data broadcast button B19, the color button B4, and the digital button B3 to emit light for a predetermined period of time.

Further, for example, in a case where the content information INF2 includes information indicating that the content being displayed is content provided by a moving image streaming service, the light emission controller 58 generates light emission control information INFBL giving an instruction to cause the light emitting device corresponding to the moving image content operation button B16 (fig. 2) in the light emitting unit 32 to emit light for a predetermined period of time.

Next, the light emission controller 58 starts the light emission of the light emitting unit 32 based on the light emission control information INFBL (step S228). Therefore, the button B in the operation unit 31 of the operation terminal 50 indicated by the light emission control information INFBL is highlighted by the light emitted from the light emitting unit 32. Then, the light emission controller 58 causes the light emitting unit 32 to end light emission after a predetermined period of time has elapsed based on the light emission control information INFBL (step S229). The sequence ends here.

As described above, in the display system 2, the control information generator 42 of the display device 40 generates the control information INF corresponding to the content being displayed by the display device 40. The light emission controller 58 of the operation terminal 50 controls the light emission operation of the light emitting unit 32 based on the control information INF. Therefore, in the display system 2, the button B that is likely to be operated by the user can be highlighted by the light from the light emitting unit 32. This enables the user to easily find the button B that the user wants to operate from among the plurality of buttons B, for example. Therefore, the display system 2 can improve the convenience of the user.

As described above, in the present embodiment, the control information generator of the display device generates control information corresponding to the content being displayed by the display device, and the light emission controller of the operation terminal controls the light emission action of the light emitting unit based on the control information. This enables the user to easily find a button that the user wants to operate, for example, which makes it possible to improve the convenience of the user. Other effects are similar to those in the case of the first embodiment.

[ modified example 2-1]

In the above-described embodiment, the control information INF includes the content information INF 2. Without being limited thereto, for example, the control information INF may include light emission control information INFBL giving an instruction of a light emission action of the light emitting unit 32 as in the case of the modified example 1-1 of the first embodiment.

[ modified example 2-2]

In the above-described embodiment, in the case where the content being displayed is audio multiplex broadcast content, subtitle content, data broadcast content, or content provided by a moving image streaming service, the button B corresponding to the content is highlighted by light from the light emitting unit 32, but the present disclosure is not limited thereto. For example, for three or less types of contents among the four types of contents, the corresponding button B may be highlighted. Specifically, for example, in the case where the content being displayed is audio multiplex broadcast content, subtitle content, or content provided by a moving image streaming service, the button B corresponding to the content may be highlighted, and in the case where the content being displayed is data broadcast content, the corresponding button B may not be highlighted.

<3. third embodiment >

Next, a description will be given about the display system 3 according to the third embodiment. The display system 3 according to the present embodiment is configured to analyze a video being displayed and control a light emitting action of a light emitting unit of an operation terminal according to the analysis result. Note that substantially the same components as those of the display system 1 according to the first embodiment are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

Fig. 16 shows a configuration example of the display system 3. The display system 3 includes a display device 60 and an operation terminal 70.

The display device 60 includes a control unit 61. The control unit 61 includes an image analyzer 63 and a control information generator 62.

The image analyzer 63 is configured to analyze the image displayed by the display unit 16 based on the video signal. Specifically, the image analyzer 63 generates information on the average color of all pixels in the frame image based on, for example, a video signal. Note that although the image analyzer 63 of the display device 60 analyzes an image in this example, the present disclosure is not limited thereto. Alternatively, for example, an external server may analyze the image.

The control information generator 62 is configured to generate control information INF for controlling the light emitting action of the light emitting unit 72 in the operation terminal 70 based on the analysis result of the image analyzer 63. Then, the control unit 61 transmits the control information INF generated by the control information generator 62 to the operation terminal 70 via the wireless communication unit 13.

The operation terminal 70 includes a light emitting unit 72 and a control unit 77.

The light emitting unit 72 is configured to be able to emit light from the entire surface of the operation surface S. Specifically, for example, by configuring the housing of the operation terminal 70 and the buttons B with a translucent material and emitting light by the light emitting unit 72, light can be enabled to be emitted from the operation surface S. The light emitting unit 72 includes, for example, a light emitting device that emits red light, a light emitting device that emits green light, and a light emitting device that emits blue light.

The control unit 77 includes a light emission controller 78. The light emission controller 78 is configured to control the light emission action of the light emitting unit 72 based on the control information INF transmitted from the display device 60.

Fig. 17 shows an action example of the display device 60. The display device 60 repeatedly performs the following actions each time a predetermined period of time (for example, about several seconds) elapses.

First, the image analyzer 63 analyzes the image displayed by the display unit 16 based on the video signal (step S301).

Next, the control information generator 62 generates image color information INF3 based on the analysis result of the image analyzer 63 (step S302). In this example, the image color information INF3 includes information on an average color in the frame image. The image color information INF3 can be represented by using, for example, a luminance signal (Y) and chrominance signals (Cr, Cb). Note that, without being limited thereto, it may be represented by using a red signal (R), a green signal (G), and a blue signal (B).

Then, the control unit 61 transmits the control information INF including the image color information INF3 to the operation terminal 70 via the wireless communication unit 13 (step S303). The flow ends here.

Fig. 18 shows an action example of the display system 3.

The image analyzer 63 of the display device 60 analyzes an image based on the video signal (step S321), and controls the information generator 62 to generate image color information INF3 based on the image analysis result (step S322). Then, the control unit 61 transmits the control information INF including the image color information INF3 to the operation terminal 70 via the wireless communication unit 13 (step S323). The control unit 77 of the operation terminal 70 receives the control information INF via the wireless communication unit 35.

The light emission controller 78 of the operation terminal 70 generates light emission control information INFBL based on the image color information INF3 included in the control information INF (step S324).

For example, in the case where the display unit 16 is displaying a scene in which something is burning, the image color information INF3 includes, for example, information about red. In this case, the light emission controller 78 generates the light emission control information INFBL by setting the light emission luminance of each light emitting device to cause the light emitting unit 72 to emit red light. Further, for example, in the case where the display unit 16 is displaying a scene of a forest, the image color information INF3 includes, for example, information on green. In this case, the light emission controller 78 generates light emission control information INFBL giving an instruction to cause the light emitting device to emit light to cause the light emitting unit 72 to emit green light. Further, for example, in the case where the display unit 16 is displaying a scene of a sea or a scene of a blue sky, the image color information INF3 includes, for example, information about blue. In this case, the light emission controller 78 generates light emission control information INFBL giving an instruction to cause the light emitting device to emit light to cause the light emitting unit 72 to emit blue light.

Next, the light emission controller 78 controls the light emission operation of the light emitting unit 72 based on the light emission control information INFBL (step S325). Accordingly, light of a color corresponding to the scene displayed by the display unit 16 is emitted from the operation surface S of the operation terminal 70.

The sequence ends here. By repeating this sequence, the operation terminal 70 can keep emitting light of a color corresponding to the scene being displayed by the display unit 16.

As described above, in the display system 3, the control information generator 62 of the display device 60 generates the control information INF corresponding to the color being displayed by the display unit 16. The light emission controller 78 of the operation terminal 70 controls the light emission operation of the light emitting unit 72 based on the control information INF. Accordingly, the operation terminal 70 can emit light of a color corresponding to the scene displayed by the display unit 16, which enables, for example, a user viewing the content to feel more realistic.

As described above, in the present embodiment, the control information generator of the display device generates control information corresponding to the color being displayed by the display unit, and the light emission controller of the operation terminal controls the light emission action of the light emission unit based on the control information. This enables the user to feel more realistic.

[ modified example 3-1]

In the above-described embodiment, the control information INF includes the image color information INF 3. Without being limited thereto, for example, the control information INF may include light emission control information INFBL giving an instruction of a light emission action of the light emitting unit 72, as in the case of the display system 1A according to modified example 1-1 of the first embodiment.

[ modified example 3-2]

In the above-described embodiment, the light emitting unit 72 capable of emitting light from the entire surface of the operation surface S is provided, but the present disclosure is not limited thereto. For example, a light-emitting unit 32B capable of highlighting the plurality of buttons B in the operation unit 31 by emitting light may be provided as in the display system 1B according to modified examples 1 to 3 of the first embodiment. In this case as well, by controlling the light emission luminance of the light emitting device of each color included in the light emitting unit 32B, light of a color corresponding to the scene displayed by the display unit 16 can be emitted from the operation surface S.

<4. fourth embodiment >

Next, a description will be given about the display system 4 according to the fourth embodiment. The display system 4 according to the present embodiment is configured to control the light emitting action of the light emitting unit of the operation terminal according to notification information when the display device notifies the user of the information. Note that substantially the same components as those of the display system 1 according to the first embodiment are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

Fig. 19 shows a configuration example of the display system 4. The display system 4 includes a display device 80 and an operation terminal 90.

The display device 80 includes a control unit 81. The control unit 81 includes a notification processor 83 and a control information generator 82.

The notification processor 83 is configured to check whether there is information to notify the user, and generate a notification message to be displayed on the display unit 16, for example, in the case where there is information to notify the user.

The control information generator 82 is configured to generate control information INF for controlling the light emitting action of the light emitting unit 32 in the operation terminal 90 based on the processing of the notification processor 83. Then, the control unit 81 transmits the control information INF generated by the control information generator 82 to the operation terminal 90 via the wireless communication unit 13.

The operation terminal 90 includes a control unit 97. The control unit 97 includes a light emission controller 98. The light emission controller 98 is configured to control the light emission action of the light emitting unit 32 based on the control information INF transmitted from the display device 80.

Furthermore, in this example, the software distribution server 202 is coupled to the internet NET. The software distribution server 202 is configured to transmit software such as firmware to the display device 60.

Fig. 20A and 20B show an action example of the display device 80.

First, the control unit 81 checks whether or not software to be updated has been newly recorded in the software distribution server 202 (step S401). If the software to be updated has been newly recorded (yes in step S401), the notification processor 83 generates a notification message indicating that there is software to be updated, and the display unit 16 displays the notification message (step S402). Then, the control information generator 82 generates notification information INF4 including information indicating that there is software to be updated (step S403).

Next, the control unit 81 checks whether the external device has been newly coupled to the external device interface 14 (step S404). If the external device has been newly coupled to the external device interface 14, the notification processor 83 generates a notification message indicating that the external device is newly coupled, and the display unit 16 displays the notification message (step S405). Then, the control information generator 82 generates notification information INF4 including information indicating that the external device is newly coupled (step S406).

Next, in a case where the recording and playback device is coupled to the external device interface 14, for example, the control unit 81 checks whether or not newly recorded content exists in the recording and playback device (step S407). If there is newly recorded content (yes in step S407), the notification processor 83 generates a notification message indicating that there is newly recorded content, and the display unit 16 displays the notification message (step S408). Then, the control information generator 82 generates notification information INF4 including information indicating that the newly recorded content exists (step S409).

Next, the control unit 81 checks whether there is a suggestion about the setting change to the user (step S410). If there is a suggestion about the setting change (yes in step S410), the notification processor 83 generates a notification message about the details of the setting change to be suggested, and the display unit 16 displays the notification message (step S411). Then, the control information generator 82 generates notification information INF4 including information indicating a recommendation about a setting change (step S412).

Next, the control unit 81 checks whether or not the content has been newly recorded in the content server 201 of the moving image streaming service (step S413). If the content has been newly recorded (yes in step S413), the notification processor 83 generates a notification message indicating that the content has been newly recorded into the moving image streaming service, and the display unit 16 displays the notification message (step S414). Then, the control information generator 82 generates notification information INF4 including information indicating that the content has been newly recorded into the moving image streaming service (step S415).

Then, the control unit 81 transmits the control information INF including the notification information INF4 to the operation terminal 90 via the wireless communication unit 13 (step S416). The flow ends here.

Fig. 21 shows an action example of the display system 4.

The notification processor 83 of the display device 80 generates a notification message, and the display unit 16 displays the notification message (step S421). The control information generator 82 generates notification information INF4 based on the processing of the notification processor 83 (step S422). Then, the control unit 81 transmits the control information INF including the notification information INF4 to the operation terminal 90 via the wireless communication unit 13 (step S423). The control unit 97 of the operation terminal 90 receives the control information INF via the wireless communication unit 35.

The light emission controller 98 of the operation terminal 90 generates light emission control information INFBL based on the notification information INF4 included in the control information INF (step S424).

For example, in a case where the notification information INF4 includes information indicating that there is software to be updated, the light emission controller 98 generates light emission control information INFBL giving an instruction to cause the light emitting device corresponding to the help button B18 (fig. 2) in the light emitting unit 32 to emit light for a predetermined period of time.

Further, for example, in a case where the notification information INF4 includes information indicating that an external device is newly coupled, the light emission controller 98 generates light emission control information INFBL giving an instruction to cause the light emitting device corresponding to the input selection button B7 (fig. 2) in the light emitting unit 32 to emit light for a predetermined period of time.

Further, for example, in a case where the notification information INF4 includes information indicating that there is newly recorded content, the light emission controller 98 generates the light emission control information INFBL giving an instruction to cause the light emitting device corresponding to the recording list button B17 (fig. 2) in the light emitting unit 32 to emit light for a predetermined period of time.

Further, for example, in a case where the notification information INF4 includes information indicating that there is a recommendation for a setting change, the light emission controller 98 generates the light emission control information INFBL giving an instruction to cause the light emitting device corresponding to the setting button B6 (fig. 2) in the light emitting unit 32 to emit light for a predetermined period of time.

Further, for example, in a case where the notification information INF4 includes information indicating that the content has been newly recorded in the moving image streaming service, the light emission controller 98 generates light emission control information INFBL giving an instruction to cause the light emitting device corresponding to the moving image service selection button B2 (fig. 2) in the light emitting unit 32 to emit light for a predetermined period of time. Specifically, for example, in the case where the content is newly recorded in the service S1 in the moving image streaming service, the light emission controller 98 may generate the light emission control information INFBL giving an instruction to light the light emitting device of the button B corresponding to the service S1 in the moving image service selection button B2.

Next, the light emission controller 98 causes the light emitting unit 32 to start light emission based on the light emission control information INFBL (step S425). Therefore, the button B in the operation unit 31 of the operation terminal 90 indicated by the light emission control information INFBL is highlighted by the light emitted from the light emitting unit 32. Then, the light emission controller 98 causes the light emitting unit 32 to end light emission after a predetermined period of time has elapsed based on the light emission control information INFBL (step S426). The sequence ends here.

As described above, in the display system 4, the control information generator 82 of the display device 80 generates the control information INF corresponding to the information to be notified to the user. The light emission controller 98 of the operation terminal 90 controls the light emission operation of the light emitting unit 32 based on the control information INF. Therefore, in the display system 4, the button B that may be operated by the user can be highlighted by the light from the light emitting unit 32. This enables the user to easily find the button B that the user wants to operate from among the plurality of buttons B, for example. Therefore, the display system 4 can improve the convenience of the user.

As described above, in the present embodiment, the control information generator of the display device generates control information corresponding to information to be notified to the user, and the light emission controller of the operation terminal controls the light emission action of the light emitting unit based on the control information. This enables the user to easily find a button that the user wants to operate, for example, which makes it possible to improve the convenience of the user. Other effects are similar to those in the case of the first embodiment.

[ modified example 4-1]

In the above-described embodiment, the control information INF includes the notification information INF 4. Without being limited thereto, for example, the control information INF may include light emission control information INFBL giving an instruction of a light emission action of the light emitting unit 32 as in the case of the display system 1A according to modified example 1-1 of the first embodiment.

[ modified example 4-2]

In the above-described embodiment, the software distribution server 202 distributes software, but the present disclosure is not limited thereto. For example, a broadcast station can distribute software by using digital broadcast waves. In this case, the control unit 81 can check whether the software has been updated based on the software supplied by using the digital broadcast wave.

[ modified examples 4-3]

In the above-described embodiment, as shown in steps S425 and S426, the button B corresponding to the notification information in the operation terminal 90 is highlighted by the light from the light emitting unit 32 for a predetermined period of time, but the present disclosure is not limited thereto. Alternatively, for example, when the display unit 16 of the display device 80 displays the notification message in step S421, the button B corresponding to the notification message may be highlighted in a period in which the display unit 16 displays the notification message.

[ modified examples 4-4]

Although the above embodiments describe information to notify a user with reference to some examples, the present disclosure is not limited thereto. For example, in a case where content associated with content viewed by a user can be viewed by broadcasting, a moving image streaming service, or the like, the display unit 16 may display a notification message indicating the case, and the button B corresponding to the notification message may be highlighted by light from the light emitting unit 32.

Specifically, in the display device 80, for example, when the user finishes watching a broadcast movie, the notification processor 83 generates a notification message indicating that other movies related to the movie director of the movie can be watched in the service S1 in the moving image streaming service, and the display unit 16 displays the notification message. The control information generator 82 generates notification information INF4 corresponding to the notification message, and the control unit 81 transmits the control information INF including the notification information INF4 to the operation terminal 90 via the wireless communication unit 13. Based on the notification information INF4 included in the control information INF, the operation terminal 90 highlights the button B corresponding to the service S1 of the moving image service selection buttons B2 by light from the light emitting unit 32.

Further, for example, in the case where the user watches an official trailer of a drama via the moving image streaming service, the notification processor 83 creates a notification message indicating that the drama is viewable via a Video On Demand (VOD) service of a set top box coupled to the external device interface 14, and the display unit 16 displays the notification message. The control information generator 82 generates notification information INF4 corresponding to the notification message, and the control unit 81 transmits the control information INF including the notification information INF4 to the operation terminal 90 via the wireless communication unit 13. The operation terminal 90 highlights the input selection button B7 by light from the light emitting unit 32 based on the notification information INF4 included in the control information INF.

As described above, the display device 80 can recommend content to the user by displaying a notification message based on the content viewed by the user. Then, the operation terminal 90 highlights the button B corresponding to the way in which the recommended content can be viewed. This enables the user to easily find a button to be operated to view the content, which makes it possible to improve the convenience of the user.

[ modification examples 4 to 5]

In the above-described embodiment, the light-emitting unit 32 of the operation terminal 90 emits light based on the notification information INF4 that is transmitted from the display device 80 and is associated with the content, but the present disclosure is not limited thereto. For example, the notification processor 83 of the display device 80 may generate a notification message according to the state of a battery contained in the operation terminal 90, and the display unit 16 may display the notification message. Specifically, in a state where the remaining amount of the battery contained in the operation terminal 90 has fallen below a predetermined level, or in a case where the battery contained in the operation terminal 90 is being charged, the operation terminal 90 may transmit information related to such a state of the battery to the display device 80, and the display unit 16 of the display device 80 may display a notification message corresponding to the received information related to the state of the battery. In this case, the notification-related information (such as information related to the state of the battery) transmitted from the operation terminal 90 to the display device 80 may be information corresponding to the notification information INF4 or the control information INF, or may be information exchanged via the wireless communication unit 35 and the wireless communication unit 13.

Further, the operation terminal 90 may cause the light emitting unit 32 to emit light according to the state of the contained battery. In this case, in lighting, one or more buttons B may be highlighted in a predetermined color and predetermined timing. Specifically, when the remaining amount of the battery falls below a predetermined level, the power button B1 may be controlled to blink in red, and when charging of the battery is started, the power button B1 may be highlighted in a color other than red. In this case, a plurality of buttons B (e.g., a power button B1 and a numeric button B3) may be highlighted. Further, the display device 80 or the operation terminal 90 may make the highlighted representation of the button B of the operation terminal 90 and the notification message displayed on the display unit 16 correspond to each other. Specifically, the color or timing of light emission by the light-emitting unit 32 and the color or timing of the notification message displayed on the display unit 16 may be made to correspond to each other. In this case, for example, if the remaining amount of battery of the operation terminal 90 falls below a predetermined level, or if charging of the battery is started, the color and the blinking frequency of the light emission of the light emitting unit 32 may be controlled to be the same as those of the notification message displayed on the display unit 16. Further, in the case where the battery of the operation terminal 30 is charged by the wireless power source, the operation terminal 90 may transmit information related to the state of the battery or the light emission of the light emitting unit 32 to the display device 80 when placed on a wireless power source charger.

<5. fifth embodiment >

Next, a description will be given about the display system 5 according to the fifth embodiment. The display system 5 according to the present embodiment is configured to control a light emitting action of a light emitting unit of an operation terminal according to a voice assistant selected by a user in a case where a plurality of voice assistants (voice assistants) are mounted on a display device. Note that substantially the same components as those of the display system 1 according to the first embodiment are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

Fig. 22 shows a configuration example of the display system 5. The display system 5 includes a display device 100 and an operation terminal 110.

The display device 100 includes a control unit 101. The control unit 101 includes two voice assistant processors 103 (voice assistant processors 103A and 103B) and a control information generator 102.

The voice assistant processor 103 is configured to perform processing corresponding to an instruction of the user included in the voice data based on the voice data of the user. Voice assistant processor 103A implements the functionality of voice assistant VA and voice assistant processor 103B implements the functionality of voice assistant VB. The user selects a voice assistant to be used from among the voice assistants VA and VB by operating the voice assistant call button B5 of the operation terminal 110. The control unit 101 of the display device 100 selects one of the voice assistants VA and VB based on the button operation code received from the operation terminal 110 via the wireless communication unit 13 and corresponding to the operation of the voice assistant call button B5.

In the case where the button operation code transmitted from the operation terminal 110 indicates that the user selects the operation of the voice assistant VA, the voice assistant processor 103A transmits voice data subsequently transmitted from the operation terminal 110 to the server 204A coupled to the internet NET. Then, the voice assistant processor 103A performs processing corresponding to the instruction of the user included in the voice data based on the information analyzed by the server 204A.

In the case where the button operation code transmitted from the operation terminal 110 indicates that the user selects the operation of the voice assistant VB, the voice assistant processor 103B transmits voice data subsequently transmitted from the operation terminal 110 to the server 204B coupled to the internet NET. Then, the voice assistant processor 103B performs processing corresponding to the instruction of the user included in the voice data based on the information analyzed by the server 204B.

The control information generator 102 is configured to generate control information INF for controlling the light emitting action of the light emitting unit 112 in the operation terminal 110 according to a voice assistant selected by the user from the two voice assistants VA and VB. Then, the control unit 101 transmits the control information INF generated by the control information generator 102 to the operation terminal 110 via the wireless communication unit 13.

The operation terminal 110 includes a light-emitting unit 112, a microphone 113, and a control unit 117.

The light emitting unit 112 is configured to highlight the plurality of buttons B in the operation unit 31 by emitting light. The light emitting unit 112 includes, for example, a plurality of light emitting devices. The plurality of light emitting devices include, for example, a light emitting device that emits red light, a light emitting device that emits green light, and a light emitting device that emits blue light.

The microphone 113 is configured to convert, for example, a user's voice into an electric signal. The control unit 117 generates voice data based on the electric signal supplied from the microphone 113, and transmits the voice data to the display device 100 via the wireless communication unit 35.

For example, in a case where the user operates the voice assistant call button B5 (fig. 2), the control unit 117 transmits a button operation code via the wireless communication unit 35. The button operation codes include a press code indicating that the voice assistant call button B5 has been pressed and a release code indicating that the pressed voice assistant call button B5 has been released.

The control unit 117 includes a light emission controller 118. The light emission controller 118 is configured to control the light emission action of the light emitting unit 112 based on the control information INF transmitted from the display device 100.

Here, the display apparatus 100 corresponds to a specific example of "information processing apparatus" according to the present disclosure. The control information generator 102 corresponds to a specific example of the "generator" according to the present disclosure. The voice assistant processor 103 corresponds to a specific example of a "voice analyzer" according to the present disclosure.

Fig. 23 shows an action example of the display device 100.

First, the control unit 101 checks whether a user operation to the voice assistant call button B5 has been detected (step S501). For example, in the case where the voice assistant VA is selected, the user presses the voice assistant call button B5 (fig. 2) in the operation terminal 110 for a short time. In the case where the voice assistant VB is selected, the user presses the voice assistant call button B5 (fig. 2) for a long time. The control unit 101 selects the voice assistant VA in a case where the button operation code received via the wireless communication unit 13 indicates that the voice assistant call button B5 (fig. 2) has been pressed for a short time, and selects the voice assistant VB in a case where the button operation code received via the wireless communication unit 13 indicates that the voice assistant call button B5 (fig. 2) has been pressed for a long time. If no user operation of the voice assistant call button B5 is detected (no in step S501), the flow ends.

Note that in this example, the operation of selecting the voice assistant VA or VB is performed based on the length of time the voice assistant call button B5 is pressed, but is not limited thereto. For example, the operation of selecting the voice assistant VA or VB may be performed based on the number of times the voice assistant call button B5 is pressed. For example, the control unit 101 may select the voice assistant VA in a case where the button operation code received via the wireless communication unit 13 indicates that the voice assistant call button B5 has been pressed once, and may select the voice assistant VB in a case where the button operation code received via the wireless communication unit 13 indicates that the voice assistant call button B5 has been pressed twice consecutively.

If a user operation to the voice assistant call button B5 is detected in step S501, the control unit 101 transmits a microphone activation code to the operation terminal 110 via the wireless communication unit 13 (step S502).

Next, it is checked whether the voice assistant VA has been selected (step S503). If the voice assistant VA has been selected (yes in step S503), the control information generator 102 generates assistant information INF5 including information indicating that the voice assistant VA has been selected (step S504). Further, if the voice assistant VB has been selected (no in step S503), the control information generator 102 generates assistant information INF5 including information indicating that the voice assistant VB has been selected (step S505).

Then, the control unit 101 transmits the control information INF including the assistant information INF5 to the operation terminal 110 via the wireless communication unit 13 (step S506). The flow ends here.

Fig. 24 shows an action example of the display system 5 in the case where the user operates the voice assistant call button B5.

When the user operates the voice assistant call button B5 of the operation terminal 110, the control unit 117 of the operation terminal 110 detects the operation and changes the action state of the operation terminal 110 from the sleep state to the normal action state (step S521). Then, the control unit 117 transmits a button operation code corresponding to an operation to the voice assistant call button B5 via the wireless communication unit 35 (step S522). The control unit 101 of the display apparatus 100 receives the button operation code via the wireless communication unit 13.

Next, the control unit 101 of the display apparatus 100 transmits a microphone boot code to the operation terminal 110 via the wireless communication unit 13 (step S523). The control unit 117 of the operation terminal 110 receives the microphone activation code via the wireless communication unit 35. The control unit 117 activates the microphone 113 based on the microphone activation code. The operation terminal 110 thus accepts voice input.

The control unit 101 of the display device 100 selects one of the voice assistants VA and VB based on the information on the operation of the voice assistant call button B5 included in the microphone start code (step S524). The control information generator 102 generates assistant information INF5 based on the selection result of the voice assistant (step S525). Then, the control unit 101 transmits the control information INF including the assistant information INF5 to the operation terminal 110 via the wireless communication unit 13 (step S526). The control unit 117 of the operation terminal 110 receives the control information INF via the wireless communication unit 35.

The light emission controller 118 of the operation terminal 110 generates light emission control information INFBL based on the assistant information INF5 included in the control information INF (step S527).

For example, in the case where the assistant information INF5 includes information indicating that the voice assistant VA has been selected, the light-emission controller 118 generates light-emission control information INFBL giving an instruction to light the light-emitting device in the light-emitting unit 112 to highlight the voice assistant call button B5 (fig. 2) in orange, for example, during a period in which the voice assistant VA is accepting voice input.

Further, for example, in a case where the assistant information INF5 includes information indicating that the voice assistant VB has been selected, the light-emission controller 118 generates light-emission control information INFBL giving an instruction to light the light-emitting device in the light-emitting unit 112 to highlight the voice assistant call button B5 (fig. 2) in blue, for example, in a period of time during which the voice assistant VB is accepting voice input.

Next, the light emission controller 118 causes the light emitting unit 112 to start light emission based on the light emission control information INFBL (step S528). Accordingly, the voice assistant call button B5 in the operation unit 31 of the operation terminal 110 is highlighted by the light emitted from the light emitting unit 112. Then, based on the light emission control information INFBL, the light emission controller 118 causes the light emission unit 112 to end the light emission after a period in which the voice assistant accepts the voice input (step S529). The sequence ends here.

As described above, in the display system 5, the control information generator 102 of the display device 100 generates the control information INF corresponding to the selected voice assistant. The light emission controller 118 of the operation terminal 110 controls the light emission action of the light emitting unit 112 based on the control information INF. Thus, the display system 5 enables the user to easily understand the selected one of the two voice assistants VA and VB and to easily understand whether the selected voice assistant is accepting a voice input. Therefore, the display system 5 can improve the convenience of the user.

As described above, in the present embodiment, the control information generator of the display device generates the control information corresponding to the selected voice assistant, and the light emission controller of the operation terminal controls the light emission action of the light emitting unit based on the control information. This enables the user to easily understand the selected voice assistant, which makes it possible to improve the convenience of the user, for example. Other effects are similar to those in the case of the first embodiment.

[ modified example 5-1]

In the above embodiment, the control information INF includes the assistant information INF 5. Without being limited thereto, for example, the control information INF may include light emission control information INFBL giving an instruction of a light emission action of the light emitting unit 112 as in the case of the display system 1A according to modified example 1-1 of the first embodiment.

[ modified example 5-2]

In the above-described embodiment, the voice assistants to be used in the voice assistants VA and VB are selected by the user operating the voice assistant call button B5, but the present disclosure is not limited thereto. Alternatively, for example, the user may select a voice assistant to be used from among the voice assistants VA and VB by uttering voice assistant call words (call words WA and WB) associated with the voice assistants VA and VB, respectively. The following is a detailed description of the present modified example.

Fig. 25 shows a configuration example of a display system 5A according to the present modified example. The display system 5A includes a display device 100A and an operation terminal 110A.

The display device 100A includes a control unit 101A. The control unit 101 includes two voice assistant processors 103 (voice assistant processors 103A and 103B). The user selects a voice assistant to be used from among the voice assistants VA and VB by uttering voice assistant call words (call words WA and WB) associated with the voice assistant processes 103A and 103B, respectively, to the microphone 113 of the operation terminal 110A. The control unit 101A of the display device 100A selects one of the voice assistants VA and VB based on the assistant selection code that is received from the operation terminal 110A via the wireless communication unit 13 and that includes information about the voice assistant to be used.

The operation terminal 110A includes a control unit 117A. Unlike the case of the above-described embodiment, the control unit 117A performs control so that the microphone 113 always accepts voice input. The control unit 117A includes two voice processors 119 (voice processors 119A and 119B). In the case where the voice data acquired by the microphone 113 includes a voice assistant call word (call word WA) associated with the voice assistant VA, the voice processor 119A generates an assistant selection code that gives an instruction to select the voice assistant VA. Similarly, in a case where the voice data acquired by the microphone 113 includes a voice assistant call word (call word WB) associated with the voice assistant VB, the voice processor 119B generates an assistant selection code giving an instruction to select the voice assistant VB. The control unit 117A transmits the generated assistant selection code to the display device 100A via the wireless communication unit 35.

Fig. 26 shows an action example of the display device 100A.

First, the control unit 101A checks whether an assistant selection code has been received via the wireless communication unit 13 (step S531). If the assistant selection code is not received (no in step S531), the flow ends.

If the assistant selection code has been received in step S531, the control unit 101A checks whether the voice assistant VA has been selected (step S503). If the voice assistant VA has been selected (yes in step S503), the control information generator 102 generates assistant information INF5 including information indicating that the voice assistant VA has been selected (step S504). Further, if the voice assistant VB has been selected (no in step S503), the control information generator 102 generates assistant information INF5 including information indicating that the voice assistant VB has been selected (step S505).

Then, the control unit 101A transmits the control information INF including the assistant information INF5 to the operation terminal 110A via the wireless communication unit 13 (step S506). The flow ends here.

[ modified examples 5-3]

In the above-described embodiment, the microphone 113 is provided in the operation terminal 110, but is not limited thereto. Alternatively, for example, a microphone may be provided in a display device, such as the display system 5B shown in fig. 27. The display system 5B includes a display device 100B and an operation terminal 110B. The display device 100B includes a microphone 108B and a control unit 101B. The operation terminal 110B includes a control unit 117B. In this example, the control unit 101B of the display apparatus 100B generates voice data based on an electric signal supplied from the microphone 108B of the display apparatus 100B. The control information generator 102 of the display device 100B generates assistant information INF5 including information indicating that the voice assistant VA has been selected in the case where the voice assistant VA has been selected, and generates assistant information INF5 including information indicating that the voice assistant VB has been selected in the case where the voice assistant VB has been selected. The control unit 101B transmits control information INF including assistant information INF5 to the operation terminal 110B via the wireless communication unit 13.

[ modified examples 5-4]

In the above-described embodiment, two voice assistant processors 103 are provided in the display device 100, but the present disclosure is not limited thereto. A voice assistant processor may be provided in the display device and a voice assistant processor may be provided in an external device coupled to the display device. For example, the external device is a smart speaker. The display device and the external device are coupled to each other through, for example, a wireless LAN. In this example, the smart speaker generates voice data based on the user's voice and sends the voice data to a server coupled to the internet NET and associated with the smart speaker. The server analyzes the voice data. In the case where the instruction of the user included in the voice data is an instruction to operate the display device, the server transmits information on the operation instruction to the display device. Upon receiving an instruction to operate the display device from the server, the voice assistant processor of the display device generates assistant information INF5 including information indicating that the voice assistant of the display device has been selected. Then, the control unit of the display device transmits the control information INF including the assistant information INF5 to the operation terminal 110 via the wireless communication unit 13.

[ modified examples 5-5]

In the above-described embodiment, the voice assistant call button B5 (fig. 2) is highlighted by the light emitted by the light emitting unit 32 according to the selected voice assistant, but the present disclosure is not limited thereto. Alternatively, for example, all the buttons B in the operation terminal 110 may be highlighted by the light emitted from the light emitting unit 32 according to the selected voice assistant.

[ modified examples 5 to 6]

In the above embodiments, the action is performed according to the selected voice assistant, but the present disclosure is not limited thereto. For example, according to the user's instruction included in the voice data, the button B associated with the instruction may be highlighted by the light emitted from the light emitting unit 32. For example, in the case where the voice data is an instruction for viewing the content of the service S1, the button B corresponding to the service S1 of the moving image service selection buttons B2 may be highlighted by the light emitted from the light emitting unit 32.

<6. sixth embodiment >

Next, a description will be given about the display system 6 according to the sixth embodiment. The display system 6 according to the present embodiment is configured to control a light emitting action of a light emitting unit of an operation terminal according to an external device (such as a set-top box) coupled thereto in a case where the external device is coupled to a display device. Note that substantially the same components as those of the display system 1 according to the first embodiment are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

Fig. 28 shows a configuration example of the display system 6. The display system 6 includes a display device 120 and an operation terminal 130.

The display device 120 includes a control unit 121. The control unit 121 includes an external device detector 123, a handover controller 124, and a control information generator 122. In this example, the set-top box 203 is coupled to the external device interface 14 of the display device 120.

The external device detector 123 is configured to detect that an external device (in this example, the set-top box 203) is coupled to the external device interface 14, and acquire information about what type of device the external device is by communicating with the external device via the external device interface 14. Types of external devices include, for example, set-top boxes, recording and playback devices, and playback devices.

The switching controller 124 is configured to set a video source to be displayed based on information on an operation on the input selection button B7 included in the infrared signal, and set a target to be controlled by the operation terminal 130 according to the set source. Specifically, for example, a case is assumed in which the set-top box 203 coupled to the external device interface 14 is set as a video source to be displayed. In this case, when the user operates, for example, the numeric button B3, the cursor button B8, the ok button B9, the channel button B11, the moving image content operation button B16, and the record list button B17, the switching controller 124 changes the control target to the set-top box 203 based on these user operations, for example. Therefore, in the display system 6, for example, in the case where the display device 120 displays a video based on a video signal selected by the tuner 11, the user can remotely operate the display device 120 by operating the operation unit 31 of the operation terminal 130. In the case where the display device 120 displays a video based on a video signal supplied from the set-top box 203, the user can remotely operate the set-top box 203 by operating the operation unit 31 of the operation terminal 130.

The control information generator 122 is configured to generate control information INF for controlling the light emitting action of the light emitting unit 32 in the operation terminal 130 according to an external device in the case where the external device coupled to the external device interface 14 is selected as a video source to be displayed by a user, for example, the operation input selection button B7. Then, the control unit 121 transmits the control information INF generated by the control information generator 122 to the operation terminal 130 via the wireless communication unit 13.

The operation terminal 130 includes a control unit 137. The control unit 137 includes a light emission controller 138. The light emission controller 138 is configured to control the light emission action of the light emitting unit 32 based on the control information INF transmitted from the display device 120.

Here, the display device 120 corresponds to a specific example of "information processing device" according to the present disclosure. The control information generator 122 corresponds to a specific example of the "generator" according to the present disclosure. The external device interface 14 corresponds to a specific example of "connection unit" according to the present disclosure. The set-top box 203 corresponds to a specific example of "external device" according to the present disclosure. The external device detector 123 corresponds to a specific example of the "acquisition unit" according to the present disclosure.

Fig. 29 shows an action example of the display device 120. In this example, the set top box 203 has been coupled to the external device interface 14, and the external device detector 123 has detected that the set top box 203 is coupled.

First, the control unit 121 checks whether an operation of input switching to the external device has been detected, for example (step S601). Specifically, for example, in a case where the infrared signal received by the infrared receiver 12 indicates that the input selection button B7 is operated, the control unit 121 checks whether the external device is selected as the video source to be displayed after the input switching.

If an operation of input switching to the external device has been detected in step S601 (yes in step S601), the switching controller 124 sets the external device as a video source (step S602), and sets the external device as a target to be controlled by the operation terminal 130 (step S603).

Next, the control information generator 122 generates external device information INF6 corresponding to the coupled external device based on the detection result of the external device detector 123 (step S604). Specifically, for example, in the case where the set-top box is coupled as an external device, the control information generator 122 generates the external device information INF6 including information indicating that the set-top box is coupled.

Then, the control unit 121 transmits the control information INF including the external device information INF6 to the operation terminal 130 via the wireless communication unit 13 (step S605). Then, the flow ends.

Further, if an input switching operation to the display device 120 has been detected in step S601 (no in step S601), the switching controller 124 sets the display device 120 as a video source (step S606), and sets the display device 120 as a target to be controlled by the operation terminal 130 (step S607). The flow ends here.

Fig. 30 shows an action example of the display system 6 in the case where the set-top box 203 is coupled to the display device 120 and input switching to the set-top box 203 is performed.

When the user operates the input selection button B7 of the operation terminal 110, the control unit 137 of the operation terminal 130 detects the operation, and the control unit 137 changes the action state of the operation terminal 130 from the sleep state to the normal action state (step S621). Then, the infrared transmitter 34 transmits an infrared signal corresponding to the operation of the input selection button B7 (step S622). The infrared receiver 12 of the display device 120 receives the infrared signal.

Based on the information on the operation of the input selection button B7 included in the infrared signal, the switching controller 124 of the display device 120 sets the set-top box 203 as a video source (step S623), and sets the set-top box 203 as a target to be controlled by the operation terminal 130 (step S624). Then, the control information generator 122 generates external device information INF6 including information indicating that the set-top box is coupled, based on the detection result of the external device detector 123 (step S625). The control unit 121 transmits the control information INF including the external device information INF6 to the operation terminal 130 via the wireless communication unit 13 (step S626). The control unit 137 of the operation terminal 130 receives the control information INF via the wireless communication unit 35.

The light emission controller 138 of the operation terminal 130 generates light emission control information INFBL based on the external device information INF6 included in the control information INF (step S627). In this example, since the external device information INF6 includes information indicating that the set-top box is coupled, the light-emission controller 138 generates the light-emission control information INFBL giving an instruction to cause the light-emitting device of the light-emitting unit 32 corresponding to the button B for viewing the content provided from the set-top box 203 to emit light for a predetermined period of time. Specifically, the light emission controller 138 generates, for example, light emission control information INFBL giving an instruction to light the light emitting devices corresponding to the numeric button B3, the cursor button B8, the ok button B9, the return button B10, the channel button B11, the volume button B12, the moving image content operation button B16, and the recording list button B17 for a predetermined period of time.

Next, the light emission controller 138 causes the light emitting unit 32 to start light emission based on the light emission control information INFBL (step S628). Accordingly, the button B for viewing the content provided from the set-top box 203 in the operation unit 31 of the operation terminal 130 is highlighted by the light emitted from the light emitting unit 32. Then, the light emission controller 138 causes the light emitting unit 32 to end light emission after a predetermined period of time has elapsed based on the light emission control information INFBL (step S629). The sequence ends here.

As described above, in the display system 6, the control information generator 122 of the display device 120 generates the control information INF corresponding to the coupled external device. The light emission controller 138 of the operation terminal 130 controls the light emission operation of the light emitting unit 32 based on the control information INF. Accordingly, the display system 6 enables the user to easily understand the buttons B available when viewing content provided from the coupled external device. Therefore, the display system 6 can improve the convenience of the user.

As described above, in the present embodiment, the control information generator of the display device generates control information corresponding to the coupled external device, and the light emission controller of the operation terminal controls the light emission action of the light emission unit based on the control information. This enables the user to easily understand the available button B, which makes it possible to improve the convenience of the user, for example. Other effects are similar to those in the case of the first embodiment.
