  Note that (a) the HDMI receiver 100 receives the content input from which HDMI input terminal, that is, the HDMI switch 11d supplies the content input from which HDMI input terminal to the HDMI receiver (b) ) Which channel the tuner 103 receives via which content is transmitted, (c) which server the IP broadcast tuner 104 receives from which content is distributed, (d) which channel the satellite broadcast tuner 105 receives Selection control for determining whether to receive the content transmitted through the channel is performed by the CPU 118. Also, (e) playback control such as playback, stop, fast forward, rewind, chapter transition in the BD drive 102 is performed by the CPU 118.

  The video selector 107 selects any one of the videos (1) to (6). The video selected by the video selector 107 is supplied to the video processing circuit 108. Note that the CPU 118 controls which video the video selector 107 selects.

  The video processing circuit 108 adjusts the image quality of the video supplied from the video selector 107. The video processing circuit 108 scales the video supplied from the video selector 107. Here, adjustment of image quality refers to changing at least one of luminance, sharpness, and contrast, for example. Scaling refers to reducing the size while maintaining the original aspect ratio of the video to be displayed. The video that has undergone image quality adjustment and scaling by the video processing circuit 108 is supplied to the output video signal generation unit 122. Note that the CPU 118 controls how the image processing circuit 108 changes the image quality and how much the image is reduced.

  The OSD generation unit (image creation means) 106 generates an OSD image. The OSD image generated by the OSD generation unit 106 is superimposed on the video supplied from the video processing circuit 108 and supplied to the output video signal generation unit 122. When the video supplied from the video processing circuit 108 is a 3D video such as a side-by-side format or a top-and-bottom format, the OSD generation unit 106 generates an OSD image corresponding to the format. In addition, what kind of OSD image is generated is controlled by the CPU 118.

When the 3D display is selected, the output video signal generation unit 122 determines the video signal (input video signal) supplied from the video processing circuit 108 and performs processing for 3D display according to the video signal. I do. On the other hand, when 3D display is not selected and the input video signal is a 3D video signal, processing for 2D display is performed on the input video signal. When the 3D display is not selected and the input video signal is a 2D video signal, the input video signal is sent to the LCD controller (display unit) 109 without being processed.

  The LCD controller 109 drives the LCD (display unit) 110 so that the video signal is displayed based on the 2D video signal or the 3D video signal supplied from the output video signal generation unit 122. Further, the LCD controller 109 controls turning on / off of the backlight of the LCD 110. Note that the CPU 118 controls how the backlight is turned on and off.

  When displaying the 3D video signal on the LCD 110, the glasses control unit 123 switches between the display of the L video signal and the display of the R video signal on the LCD 110, and the L lens and the R lens of the 3D glasses 3. The shutter operation of the 3D glasses 3 is controlled so as to synchronize with the shutter operation. The control signal for this purpose is converted into an infrared signal by the infrared light emitting unit 124 and transmitted to the 3D glasses 3. When the 3D glasses 3 receive the infrared signal, the 3D glasses 3 perform a shutter operation with the L lens and the R lens in accordance with the instruction of the signal.

  The voice selector 111 selects any one of the voices (1) to (6). The sound selected by the sound selector 111 is supplied to the sound processing circuit 112. Note that the CPU 118 controls which sound the sound selector 111 selects. However, the selection of the video by the video selector 107 and the selection of the audio by the audio selector 111 are linked. For example, when the video selector 107 selects the video supplied from the HDMI receiver 100, the audio selector 111 is also selected. The audio supplied from the HDMI receiver 100 is selected.

  The audio processing circuit 112 adjusts the volume and quality of the audio supplied from the audio selector 111 and performs virtual surround processing of the audio. Here, the adjustment of the sound quality refers to changing the frequency characteristics of the sound supplied from the sound selector 111 (for example, emphasizing a low frequency or emphasizing a high frequency). The virtual surround processing refers to processing for converting stereo sound into sound like surround using the characteristics of human hearing. The sound processed by the sound processing circuit 112 is supplied to the digital amplifier 113. Note that the CPU 118 controls how the sound processing circuit 112 changes the sound volume and sound quality, and the degree of virtual surround.

  The digital amplifier 113 drives the speaker 114 so that the sound supplied from the sound processing circuit 112 is output. Thereby, the sound selected by the sound selector 111 is output from the speaker 114.

The CPU 118 controls each of the above units according to the remote control signal received by the infrared light receiving unit 119, the image captured by the camera 120, and the output signal output from the human sensor 121. The output signal of the human sensor 121 is a binary signal indicating whether or not a viewer exists within the sensing range. Control using the infrared light receiving unit 119 includes, for example, control for switching channels selected by the tuners 103 to 105 according to a remote control signal, and video and audio selected by the video selector 107 and the audio selector 111 as remote control signals. For example, a control to switch according to the above. The control using the camera 120 includes, for example, control for switching how the image quality is adjusted in the video processing circuit 108 according to the viewer specified based on the captured image. In addition, examples of the control using the human sensor 121 include control for switching whether the backlight of the LCD 110 is turned on or off according to the detection result.

  Further, the CPU 118 executes a CEC (Consumer Electronics Control) command received by the HDMI receiver 100 from an external device (for example, a mobile phone terminal), or generates a CEC command that the HDMI receiver 100 transmits to the external device. Realizes cooperative operation with external devices.

  The ROM 116 is a memory in which fixed data such as a program executed by the CPU 118 is stored. The ROM 116 also stores JPEG data, SVG (Scalable Vector Graphics) data, and the like referred to by the OSD generation unit 106 to generate an OSD image. On the other hand, the RAM 117 is a readable and writable memory in which variable data such as data referred to by the CPU 118 for calculation and data generated by the CPU 118 by calculation is stored.

  The Ethernet I / F 115 is an interface for connecting the 3D TV 1 to the network. The IP broadcast tuner 104 described above accesses a server on the Internet via the Ethernet I / F 115.

Next, the processing of the output video signal generation unit 122 will be specifically described.
In the 3D TV 1, 3D automatic switching can be set by an operation from the remote controller 2. This setting is confirmed by the CPU 118 and held in the RAM 117, for example.

  The process determination unit 131 shown in FIG. 4 determines whether or not the 3D automatic switching setting is performed. When the 3D automatic switching setting is performed, the input video signal (input video signal) is converted into the 3D video. It is determined whether the signal is a 2D video signal. Further, when the input video signal is a 3D video signal, it is determined whether it is a frame packing method, a side-by-side method, or a top-and-bottom method.

  Further, the process determining unit 131 determines whether or not 3D display setting is manually performed when 3D automatic switching setting is not performed, and when 3D display setting is manually performed. Then, it is determined whether the input video signal is a 3D video signal or a 2D video signal. Further, when the input video signal is a 3D video signal, it is determined whether it is a frame packing method, a side-by-side method, or a top-and-bottom method.

  When the 3D display setting is manually performed and the input video signal is a 2D video signal, the 2D → 3D conversion unit 132 generates 2D video from the 2D video in order to generate a pseudo 3D video. Convert to 3D video.

  The 3D processing unit 133 processes the input video signal according to the 3D system of the input video signal, generates a 3D video signal, and outputs the 3D video signal to the LCD controller 109. If neither the 3D automatic switching setting nor the manual 3D display setting is performed, and the input video signal is a 3D video signal, a process for displaying the 3D video signal in 2D is performed. If the input video signal is a 2D video signal when the manual 3D display setting is not performed, the processing in the 2D → 3D conversion unit 132 and the 3D processing unit 133 is performed on the input video signal. Not done.

  Next, an outline of unique functions in the present embodiment will be described.

In the system of this embodiment, an external device (not shown) that can transmit 3D video is connected via the HDMI receiver 100. The 3D TV 1 displays an operation panel for operating the external device on the screen. FIG. 5 shows an example of the operation panel. In the example of FIG. 5, the external device is a disc player.

  As shown in FIG. 5, the operation panel 200 is provided with a “3D” button (stereoscopic image instruction button) 201. When the user selects the “3D” button 201 using the remote controller 2, the 3D TV 1 uses the CEC command to instruct the external device to transmit 3D video. Thereby, 3D video can be received from the external device via the HDMI receiver 100 and the received 3D video can be displayed on the LCD 110. Therefore, the user can transmit the 3D video to the external device and display it on the 3D TV 1 simply by selecting a predetermined button on the operation panel 200, and the user convenience is improved.

  FIG. 6 is a plan view showing an example of the operation surface of the remote controller 2 of the present embodiment. As shown in FIG. 6, a “3D” button 210 for 3D video, a “brightness up” button 211, and a “surround” button 212 are provided on the operation surface of the remote controller 2.

  When the user presses the “3D” button 210, the 3D TV 1 performs 3D display. As a result, the user can display 3D video on the 3D TV 1 simply by pressing a predetermined button on the remote controller 2, and user convenience is improved.

  By the way, as described above, the user needs to wear the 3D glasses 3 in order to view the 3D video, and the visually recognized video becomes darker than when the 3D glasses 3 are not worn. On the other hand, in the present embodiment, when the user presses the “brightness up” button 211 during 3D display, the 3D TV 1 increases the luminance of the backlight of the LCD 110. Thus, the user can suppress the darkness of the visually recognized video simply by pressing a predetermined button on the remote controller 2, so that the user's convenience is improved.

  In addition, if the backlight of LCD110 is LED (Light Emitting Diode), since a brightness | luminance can be made higher than the backlight using a cold cathode tube, it is desirable. In addition, if the LCD 110 displays four primary colors in which yellow (Y) is added to the three primary colors of red (R), green (G), and blue (B), it can be displayed brighter than an LCD that displays three primary colors. desirable.

  By the way, when the 3D TV 1 performs 3D display, the user views a video having a depth. Therefore, it is desirable to output sound having a depth corresponding to a video having a depth. Thus, in the present embodiment, when the user presses the “surround” button 212 during 3D display, the 3D TV 1 outputs sound in a virtual surround with a greater depth than in the case of virtual surround during 2D display. As a result, the user can output a sound having a depth corresponding to a 3D image having a depth only by pressing a predetermined button on the remote controller 2, so that the user's convenience is improved.

  Next, details of the unique functions in the present embodiment will be described. The specific function is realized by the CPU 118 of the 3D TV 1. FIG. 7 is a functional block diagram expressing the functions of the CPU 118 of the 3D TV 1 of this embodiment. As illustrated in FIG. 7, the CPU 118 includes a user instruction acquisition unit (instruction acquisition unit) 300, a device information acquisition unit (device information acquisition unit) 301, a device instruction unit (external instruction unit) 302, and an image creation instruction unit (image (Creating means) 303. The storage device such as the ROM 116 and the RAM 117 includes a device information storage unit 304.

  The device information storage unit 304 stores various device information such as function information, status information, and setting information in the 3D TV 1. Furthermore, the device information storage unit 304 stores various device information such as function information, status information, and setting information in an external device (not shown) connected via the HDMI receiver 100.

  Note that information unique to the 3D TV 1, such as model information and device ID, is preferably stored in the ROM. Further, it is desirable to store information that should be retained even when the 3D TV 1 is turned off, such as setting information of the 3D TV 1, in a flash memory. Further, information that may be deleted when the power of the 3D TV 1 is turned off, such as status information of the 3D TV 1 and device information of an external device, may be stored in the RAM 117.

  The user instruction acquisition unit 300 acquires user instruction information created by the remote controller 2 through a user operation from the remote controller 2 via the infrared light receiver 119. The user instruction acquisition unit 300 sends the acquired user instruction information to the device information acquisition unit 301.

  The device information acquisition unit 301 acquires the device information of the 3D TV 1 and the external device from the device information storage unit 304 based on the user instruction information from the user instruction acquisition unit 300. The device information acquisition unit 301 sends the acquired device information to the device instruction unit 302 and the image creation instruction unit 303. The device information acquisition unit 301 may acquire the device information of the external device from the external device via the HDMI receiver 100.

  The device instruction unit 302 gives instructions to various devices based on the device information from the device information acquisition unit 301. Examples of the device include a BL control unit 109a that controls the backlight (BL) of the LCD 110 in the LCD controller 109, the audio processing circuit 112, the external device, and the like. The instruction to the external device is performed by transmitting a CEC command from the HDMI receiver 100 to the external device.

  The image creation instruction unit 303 instructs the OSD generation unit 106 to create an OSD image based on the device information from the device information acquisition unit 301.

  Next, processing operations relating to the operation panel 200 shown in FIG. 5 will be described. FIG. 8 is a flowchart showing a flow of processing for displaying the operation panel 200. This process is performed when the user instruction acquisition unit 300 acquires user instruction information for displaying a video from the external device from the remote controller 2 via the infrared light receiver 119. In the following description, it is assumed that the external device connected to the HDMI receiver 100 is a disc player as shown in FIG. 5, but the present invention can be applied to any external device capable of transmitting 3D video.

  As shown in FIG. 8, first, the device information acquisition unit 301 acquires the device information of the disc player connected to the HDMI receiver 100 from the device information storage unit 304, or from the disc player via the HDMI receiver 100. (S100). Next, the device information acquisition unit 301 determines from the acquired device information whether the 3D video can be transmitted (output) by the disc player (S101).

  When the 3D video can be transmitted, the image creation instruction unit 303 instructs the OSD generation unit 106 to create an image of the operation panel 200 including the “3D” button 201 (S102). As a result, the image of the operation panel 200 including the “3D” button 201 is displayed on the LCD 110, and then the above process is terminated.

On the other hand, when transmission of 3D video is impossible, the image creation instruction unit 303 instructs the OSD generation unit 106 to create an image of the operation panel 200 that does not include the “3D” button 201 (S102). As a result, an image of the operation panel 200 that does not include the “3D” button 201 is displayed on the LCD 110, and then the above process ends. Therefore, since the “3D” button 201 is not included in the displayed operation panel 200, the user can easily recognize that the 3D video cannot be transmitted by the disc player, and the usability of the user is further improved.

  In addition, as a case where transmission of 3D video by the disc player is impossible, there may be a case where the disc player does not have a function of transmitting 3D video. Alternatively, there may be a case where the disc player does not have 3D video to be transmitted, such as the disc player having the function, but no disc is inserted, or no 3D video is recorded on the disc.

  FIG. 1 is a flowchart showing the flow of processing for switching the video transmitted by the disc player between 2D video and 3D video. This process is performed when the user operates the remote controller 2 to select the “3D” button 201 on the operation panel 200.

  As shown in FIG. 1, first, the device information acquisition unit 301 acquires the output state of the disc player (S110), and determines whether or not the disc player is transmitting 3D video (S111). Note that whether or not the video from the disc player is a 3D video can be detected by the processing determination unit 131 of the output video signal generation unit 122.

  If the 3D video is being transmitted, the device instruction unit 302 instructs the disc player via the HDMI receiver 100 to transmit the 2D video (S112). On the other hand, when the 3D video is not transmitted, that is, when the 2D video is transmitted or the video itself is not transmitted, the device instruction unit 302 transmits the 3D video via the HDMI receiver 100 so as to transmit the 3D video. The disc player is instructed (S113).

  Next, the image creation instruction unit 303 instructs the OSD generation unit 106 to update the image on the operation panel 200 (S114). Specifically, when 3D video is being transmitted, the “3D” button 201 is changed to an on-state image, and when 2D video is being transmitted, the “3D” button 201 is turned off. The OSD generation unit 106 is instructed to change to an image.

  Therefore, the user can select the “3D” button 201 on the operation panel 200 to transmit the 3D video to the disc player and display it on the 3D TV 1, which improves user convenience.

  Next, the processing operation relating to the “brightness up” button 211 shown in FIG. 6 will be described. FIG. 9 is a flowchart showing the flow of processing performed when the “brightness up” button 211 is pressed.

  As shown in FIG. 9, first, the device information acquisition unit 301 acquires the display state of the 3D TV 1 (S120), and determines whether or not a 3D video is being displayed (S121). When the 3D video is not displayed, that is, when the 2D video is displayed or the display itself is not performed, the image creation instruction unit 303 instructs the OSD generation unit 106 to create an error message. (S122). Thereby, for example, an error message “can be used only during 3D viewing” is displayed, and then the above process is terminated. Therefore, it is possible to avoid the problem that the displayed video is too dazzling by increasing the brightness of the backlight during 2D display.

On the other hand, when the 3D video is displayed, the device information acquisition unit 301 acquires the brightness setting value from the device information storage unit 304 (S123), and the device instruction unit 302 sets the backlight to the acquired setting value. The BL controller 109a of the LCD controller 109 so as to increase the luminance.
(S124). Note that increasing the luminance of the backlight can be realized by lengthening the lighting time of the backlight.

  Next, the image creation instruction unit 203 instructs the OSD generation unit 106 to create a message corresponding to the acquired setting value (S125). FIG. 10A shows a display example of the message. Note that the luminance setting value may be one, but is preferably plural. In the present embodiment, four setting values including three predetermined setting values and a setting value selected by the user are stored in the device information storage unit 304 as the luminance setting values. FIG. 10B shows an example of messages corresponding to these four setting values.

  Next, the user instruction acquisition unit 300 waits until user instruction information indicating that the “brightness up” button 211 is pressed again within a predetermined period is acquired from the remote controller 2 via the infrared light receiver 119 ( S126 and S127). When the user instruction information is acquired within a predetermined period, the device information acquisition unit 301 acquires another set value from the device information storage unit 304 (S128).

  As shown in FIG. 11, first, the device information acquisition unit 301 acquires the display state of the 3D TV 1 (S130), and determines whether or not a 3D video is being displayed (S131). When the 3D video is not displayed, that is, when the 2D video is displayed or the display itself is not performed, the image creation instruction unit 303 instructs the OSD generation unit 106 to create an error message. (S132). Thereby, for example, an error message “can be used only during 3D viewing” is displayed, and then the above process is terminated. Therefore, it is possible to avoid the problem of giving the user an uncomfortable feeling by outputting the virtual surround sound for 3D display with depth during 2D display without depth.

  On the other hand, when the 3D video is displayed, the device information acquisition unit 301 acquires the virtual surround setting value from the device information storage unit 304 (S133), and the device instruction unit 302 uses the acquired setting value to perform virtual surround. The voice processing circuit 112 is instructed to execute the process (S134). The virtual surround setting value indicates the degree of the depth.

Next, the image creation instruction unit 203 instructs the OSD generation unit 106 to create a message corresponding to the acquired setting value (S135). FIG. 12A shows a display example of the message. In addition, although the said setting value may be one, it is preferable that it is plural. In the present embodiment, as the setting values, four setting values, that is, three setting values set in advance and the setting value is zero, that is, the virtual surround process is not executed, are the device information storage unit 304.
Is remembered. FIG. 12B shows an example of messages corresponding to these four setting values.

  Next, the user instruction acquisition unit 300 waits until user instruction information indicating that the “surround” button 212 has been pressed again within a predetermined period is acquired from the remote controller 2 via the infrared light receiver 119 (S136 •). S137). When the user instruction information is acquired within a predetermined period, the device information acquisition unit 301 acquires another set value from the device information storage unit 304 (S138). Then, it returns to step S134 and repeats the said operation | movement.

  On the other hand, when the predetermined period has elapsed without acquiring the user instruction information, the above process is terminated. At this time, it is desirable that the image creation instruction unit 203 instructs the OSD generation unit 106 to stop displaying the message corresponding to the set value.

  Accordingly, since the user can output the virtual surround sound with the depth corresponding to the 3D video with the depth by simply pressing the “surround” button 212 of the remote controller 2, the user convenience is improved. In addition, since the virtual surround sound can be changed to another depth by simply pressing the “surround” button 212, the user convenience is improved.

As shown in FIG. 14, first, the device information acquisition unit 301 acquires the display state of the 3D TV 1 (S140), and determines whether or not a 3D video is being displayed (S141). When the 3D video is being displayed, the device information acquisition unit 301 prohibits the setting of 2D surround, and the image creation instruction unit 303 instructs the OSD generation unit 106 to display to that effect (S142). As a result, for example, as shown in FIG. 13, the 2D surround setting item 221 is toned down and a prohibition mark is added.

  On the other hand, when the 3D video is not displayed, that is, when the 2D video is displayed or when the display itself is not performed, the device information acquisition unit 301 prohibits the setting of the 3D surround and displays a display to that effect. As shown, the image creation instruction unit 303 instructs the OSD generation unit 106 (S143). Thereby, for example, the 3D surround setting item 222 is toned down and a prohibition mark is added. Therefore, by setting and outputting 3D surround sound with depth during 2D display without depth, or setting and outputting sound with 2D surround sound without depth during 3D display with depth, Problems such as giving the user a sense of incongruity can be avoided.

  Next, the device information acquisition unit 301 acquires various setting items and setting values related to audio adjustment from the device information storage unit 304 (S144), and creates an image of a setting menu including the acquired setting items and setting values. The OSD generation unit 106 is instructed as follows. As a result, an image of the setting menu as shown in FIG. 13 is displayed.

  Next, the user instruction acquisition unit 300 waits until user instruction information indicating the end of adjustment or user instruction information for instructing adjustment is acquired from the remote controller 2 via the infrared light receiving unit 119 (S146 and S147). When the user instruction information for instructing the adjustment is acquired, the device instruction unit 302 controls the corresponding device (for example, the voice processing circuit 112) according to the user instruction information (S148), and sets the setting information in the device information storage unit 304. Update (S149). Then, it returns to step S145 and repeats the said operation | movement.

  On the other hand, when user instruction information indicating the end of adjustment is acquired, the image creation instruction unit 203 instructs the OSD generation unit 106 to stop displaying the image of the setting menu, and then the process ends.
