As a result of this, the viewer can view the video easier than before and can also operate the remote controller easily.

Description

  The present invention relates to a three-dimensional video display device that displays a stereoscopic video.

  In recent years, stereoscopic image display devices that stereoscopically display still images and moving images have been reduced in price due to the progress of manufacturing technology, the liquid crystal display device itself has become thinner and lighter, and the development of image quality enhancement technology in display functions. It is rapidly spreading and is widely used in monitors for personal computers and digital TVs that receive and display digital broadcast waves. There are various display methods for stereoscopic video display devices, but the common point among them is that the video displayed using the parallax of the human right and left eyes is perceived as stereoscopic. It is. As conventional techniques, stereoscopic video display devices that display left and right images alternately in time, and stereoscopic video viewing glasses that open and close left and right shutter glasses in synchronization with synchronization signals such as infrared synchronization pulses emitted from the display devices And a stereoscopic video system.

  FIG. 17 is a diagram showing the positional relationship between the 3D video display device and the viewer from above. A viewer 1720 who views a stereoscopic video is positioned in front of the 3D video display device 1700. When the remote controller is operated by volume control or the like, a volume display menu screen that is superimposed by the remote controller is displayed. The depth plane is different. Specifically, the video viewed by the viewer via the stereoscopic video viewing glasses 1710 is the video superimposed on the 3D video as shown in FIG. When viewing a video displayed on a stereoscopic video display device through glasses for stereoscopic video viewing, the depth plane differs from the volume display menu, and the viewer feels uncomfortable, making it difficult to control the volume with the remote control. It was. FIG. 19 shows the original three-dimensional original image by the recording device at that time, the image of the superimpose screen, the left shutter signal, the right shutter signal, the image entering the human left eye, and the human image. This shows the timing relationship with the video entering the right eye.

  When viewing through 3D stereoscopic viewing glasses, the left and right images are alternately displayed, so the brightness of the image through the glasses is halved, the brightness through the glasses decreases, and the screen appears dark, making remote control difficult to operate. There are also challenges.

Japanese Patent Laid-Open No. 9-9296 JP 2003-9185 A

  Patent Document 1 describes the following technique. In a stereoscopic video apparatus that displays 3D video using glasses in a time-sharing manner for the left and right eyes, when the power is turned on, the viewer often does not wear stereoscopic video viewing glasses. The viewer sees the three-dimensional double image, which leads to discomfort and a reduction in visual acuity. In order to avoid this, the supply of the stereoscopic video signal is prohibited when the power supply circuit is reintroduced, and a remote control operation or the like is performed on the two-dimensional video.

  Patent Document 2 describes the following technique. In a three-dimensional goggles endoscope, a left LCD and a right LCD are arranged in front of the viewer's left and right eyes, respectively, and a left and right subject is observed by a sequential signal of the L / R field, and stereoscopically viewed. When displaying character information such as a menu, the character is displayed only on one eye side, or when displaying character information on both eyes, the position is shifted and it is difficult to see. As a solution to this, it is disclosed that a three-dimensional reset signal is generated by an operation with a remote controller to cancel the three-dimensional mode, and a two-dimensional mode in which the same display is made on the left and right to make the character information easier to see. FIG. 20 shows a configuration diagram of the endoscope remote controller 2010, the FMD 2020, and the FMD adapter 2030. With these configurations, when the menu button of the remote controller 2010 is pressed, when the index button is pressed, when the image processing measurement button is pressed, or when the power button is pressed, the 3D image displayed on the FMD 2020 is displayed. Was released to become 2D video.

  The prior art disclosed in Patent Document 1 is that stereoscopic glasses viewing glasses expect viewers to take off their glasses and display images in two dimensions only at that time. However, it was not a solution when the remote control was operated during video viewing.

  The prior art disclosed in Patent Document 2 is to make it easier for a viewer to operate a remote control by resetting a 3D video in a video device, which is a stereoscopic video viewing FMD, to a 2D video. However, it cannot be used for the shutter-type three-dimensional glasses method.

  The three-dimensional video display device of the present application includes a video display unit that displays a stereoscopic video, a signal reception unit that receives an operation instruction command from the outside, and a stereoscopic video displayed on the video display unit when the stereoscopic video is displayed. A synchronization signal that synchronizes with the left and right images of the image, generates a synchronization signal that instructs viewing of the stereoscopic image, and instructs the viewing of only one of the left and right of the stereoscopic image when the signal receiving unit receives an operation instruction command from the outside A command signal generator for generating the signal, and a signal transmitter for transmitting the generated synchronization signal to the three-dimensional glasses.

  Thus, it is possible to suppress a problem that it is difficult to see the video display of the operation when performing a remote control operation or the like.

  In the three-dimensional video display device, when the signal receiving unit receives an operation instruction command from the outside, the video display unit includes a two-dimensional image corresponding to the operation instruction command on at least one of the left and right images constituting the stereoscopic video. Synchronizing the command signal generation unit to instruct control to view only one of the left and right of the stereoscopic video when the video display unit displays the duplicated video. It may be one that generates a signal.

  In the above description, the synchronization signal instructing viewing of only one of the left and right images of the stereoscopic image is the left and right shutters of the three-dimensional glasses when either the left or right image is displayed on the image display unit. When the other image is displayed on the image display unit, the left and right shutters of the three-dimensional glasses may be closed.

  In the above description, the synchronization signal instructing to view only one of the left and right images of the stereoscopic image is the left or right one of the three-dimensional glasses when either the left or right image is displayed on the image display unit. When only the shutter is opened, and the other video is displayed on the video display unit, both the left and right shutters of the three-dimensional glasses may be closed.

  As a result, it is possible to suppress the problem that the operation screen is displayed on the 3D video display and is difficult to see.

Another 3D image display device of the present application alternately displays a signal receiving unit that receives an operation instruction command from the outside and left and right images constituting the 3D image alternately in time when the 3D image is displayed. When the signal receiving unit receives an operation instruction command from the outside, the video that alternately displays temporally one video of the left and right videos constituting the stereoscopic video and the other video generated from the one video A display unit, a command signal generation unit that generates a synchronization signal synchronized with the video displayed on the video display unit, a signal transmission unit that transmits the generated synchronization signal to three-dimensional glasses,
Is provided.

  As a result, the viewer views only one of the left and right videos on which the operation video is displayed, and the problem that the operation screen is displayed on the three-dimensional video display and is difficult to see can be suppressed.

  In the above invention, the command signal generation unit displays the video display unit alternately alternately in time with one of the left and right videos constituting the stereoscopic video and the other video generated from the one video. In this case, a synchronization signal for opening and closing the left and right shutters of the three-dimensional glasses may be generated.

  Further, in the above invention, the command signal generation unit displays the video display unit alternately in time with one of the left and right videos constituting the stereoscopic video and the other video generated from the one video. In this case, a synchronization signal for opening both the left and right shutters of the three-dimensional glasses may be generated.

  As a result, it is possible to suppress the problem that the operation screen is displayed on the 3D video display and is difficult to see.

When operating a remote control using 3D glasses when viewing 3D images, the display image of the remote control operation is doubled left and right by the shutter control of the 3D glasses, and the perspective is displayed incorrectly. Improve the difficulty of operation.

  Further, the state in which the three-dimensional glasses simultaneously open and close the left and right shutters by the remote control operation is continued during the overlay period, so that the screen of the video display device through the glasses becomes bright and the remote control operation becomes easy.

(Embodiment 1)
FIG. 1 is a diagram showing a configuration of a 3D video display system. The 3D video display system includes a 3D video display device 1, 3D glasses 2, and a remote control infrared light emitting device 3.

  The 3D video display device 1 is a video display device for displaying a 3D video. The three-dimensional video display device 1 includes a three-dimensional original video generation unit 4, a video data overlay unit 5, a video display unit 6, a glasses infrared command signal light emission unit 7, a glasses command electric light conversion unit 8, and a glasses command.

  The remote control infrared light emitting device 3 is a device for instructing the operation or the like from the viewer to the 3D video display device 1. The remote control infrared light emitting device 3 includes a remote control infrared signal light emission unit 25, a remote control electric light signal conversion unit 26, and a viewer remote control key unit 27.

  FIG. 2 is a flowchart illustrating an example of a control flow of the 3D video display system. 2A shows signal processing of the remote control infrared light emitting device 3, FIG. 2B shows signal processing of the 3D video display device 1, and FIG. 2C shows signal processing of the 3D glasses 2. .

  Signal processing of the remote control infrared light emitting device 3 will be described with reference to FIG. The remote control infrared light emitting device 3 enters an input waiting state (step 30) waiting for an event that the viewer presses the remote control key 27 to occur.

  When the viewer inputs a key for increasing the volume, for example, the remote control infrared light emitting device 3 detects the type of the input key (step 31).

  The remote control infrared light emitting device 3 emits an infrared signal in accordance with the key type input in step 31 (step 32).

  Signal processing of the 3D video display device will be described with reference to FIG. The three-dimensional image display device 1 receives the infrared signal emitted at step 32 of the remote control infrared light emitting device 3 at the remote control infrared signal light receiving unit 12 (step 41).

  The remote control photoelectric conversion unit 11 converts the infrared signal (optical signal) received in step 41 into an electrical signal (step 42).

  The remote control command analysis unit 10 analyzes the logical meaning of the received command based on the electrical signal converted in step 42 (step 43). In the present embodiment, for the purpose of explanation, the remote control command analysis unit 10 will be described below by taking as an example the case where the received command is a command for raising the volume.

  The superimposing 2D video generation unit 16 generates a volume display video 55 indicating the volume level as shown in FIG. 3 based on the analysis result of step 43 (step 44).

  The video data overlay unit 5 overlays the 3D video from the 3D video generation unit 4 or the like and the volume video 55 generated in step 44 (step 45).

  The video display unit 6 displays the video overlaid in step 45 (step 46).

  The spectacles command signal generation unit 9 is a command to be sent to the three-dimensional glasses 2 as a command to increase the volume analyzed by the remote control command analysis unit 10 in step 43 or a command to adjust the volume indicating the type of these controls. A signal is generated (step 47).

  The eyeglass command electro-optic conversion unit 8 converts the electrical signal command generated by the eyeglass command signal generation unit 9 into an optical (infrared) signal command (step 48).

The eyeglass infrared command signal light emitting unit 7 outputs the optical signal generated in step 48 to the three-dimensional glasses 2 (step 49).
Signal processing of the three-dimensional glasses 2 will be described with reference to FIG. The three-dimensional glasses 2 receive the optical signal emitted in step 49 of the three-dimensional image display device 1 by the glasses infrared command light receiving unit 17 (step 61).

  The spectacles command photoelectric conversion unit 18 converts the optical signal (infrared ray) received in step 61 into an electrical signal (step 62).

  The eyeglass command analysis unit 21 analyzes the logical meaning of the command converted into the electrical signal (step 63). In the description of the present embodiment, since the command has a content meaning volume adjustment, the glasses command analysis unit 21 analyzes and determines that the command is volume adjustment.

  Based on the analysis result of the glasses command analysis unit 21, the three-dimensional glasses 2 selectively branches the subsequent processing. Specifically, it is determined whether the command analyzed in step 63 is a command for 3D video or a command for 2D video (step 64). The command for 3D video corresponds to, for example, a command for opening the left shutter, a command for closing the left shutter, a command for opening the right shutter, a command for closing the right shutter, and the like. On the other hand, the command for 2D video corresponds to, for example, a command for simultaneously opening and closing both left and right shutters, a command for simultaneously closing, and the like. The 3D glasses 2 determines whether the received command is a 3D video command or a 2D video command based on a database or the like stored in the reference command list unit 20 indicating the type of each received command. can do.

  If it is determined in step 64 that the command is for 3D video, the 3D video processing shutter control unit 22 performs shutter control for 3D video on the eyeglass shutter unit 24 (step 65). Specifically, the 3D video display device 1 opens and closes the left and right shutters of the eyeglass shutter unit 24 in synchronization with the left-eye video and the right-eye video to be displayed.

  If it is determined in step 65 that the command is for a two-dimensional video, the two-dimensional binocular simultaneous open and simultaneous shutter control unit 23 performs shutter control for the two-dimensional video on the eyeglass shutter unit 24 (step 66). . Specifically, when the 3D image display apparatus 1 superimposes the volume adjustment display as described above, one image is displayed so that only one of the left and right images is viewed. In such a case, control is performed so that the shutters for both eyes of the three-dimensional glasses 2 are opened and the shutters for both eyes are closed when the other image is displayed.

  FIG. 3 shows an image viewed by the viewer when the remote control infrared device 3 outputs a volume adjustment command and the 3D glasses 2 perform a shutter opening / closing operation for 2D images, as shown in the flowchart of FIG. It is a figure explaining the example of.

  In N frames, the left-eye three-dimensional image 73 and the right-eye three-dimensional image 74 are original images that are shifted to the left and right by the amount of parallax. The left-eye superimposing image 75 and the right-eye superimposing image 76 are two-dimensional images that are not three-dimensionalized. That is, the images 75 and 76 are the same on the left and right. The eyeglass shutter unit 24 opens the binocular shutter while the left-eye three-dimensional image 73 is displayed. Conversely, while the right-eye three-dimensional image 74 is displayed, the eyeglass shutter unit 24 closes the binocular shutter. As a result, the viewer who views the 3D glasses 2 views the overlay image of the left eye image 73 and the superimpose image 75, so that the superimposed volume adjustment display does not shift from side to side.

  The volume adjustment command from the remote control infrared light emitting device 3 emits a signal only once or only a predetermined number of times, but the video data overlay continuation determination unit 13 However, while the overlay display continues, transmission of the spectacle command to the three-dimensional spectacles 2 may be continued by the spectacle command continuation unit 14 or the like.

  The three-dimensional glasses 2 continue the two-dimensional binocular simultaneous open / close shutter control by the continuous reception of the spectacle commands from the above and the three-dimensional video display device 1, and the binocular shutter simultaneous open state and the binocular shutter simultaneous Repeat the closed state. As a result, the viewer continues in a state where the volume display or the like does not fluctuate left and right.

  If it is determined in step 50 of FIG. 2B that the superimposed superimposed video is finished, the 3D video display device 1 switches the command to be transmitted to the 3D glasses 2 to the 3D glasses command. In the eyeglass command analysis 44 of the 3D glasses 2, the glasses shutter unit 24 is controlled by the 3D image processing shutter control unit 22, and glasses shutter 3D display driving is performed. Thus, immediately after the overlay is finished, the original 3D image enters the human eye.

  FIG. 4 is a diagram showing timing control in the operation example shown in FIG. The video of the 3D video display device 1 is displayed alternately in time with a left-eye video, a right-eye video, and a left-eye video. Similarly, the superimpose video is displayed alternately in time with the left eye video, the right eye video, and the left eye video. The left-eye shutter signal is turned on only for the left-eye image, the right-eye shutter signal is turned on only for the left-eye image, and then the left-eye shutter signal is turned off when the right-eye image is displayed. When the signal is also a right eye image, the signal is turned off. Thus, the image that enters the human left eye is only the left eye image, and the image that enters the human right eye is only the left eye image.

  In this way, when viewing a 3D image, when operating the remote control using 3D glasses, the depth surface differs between the 3D image and an overlaid superimposed image, for example, a volume display menu. It is possible to improve the difficulty of operating the remote control volume due to a sense of incongruity.

  In this example, the volume operation of the remote control is described, but the same applies to other remote control operations. For example, the same applies to video adjustment, input terminal switching, channel display, and the like.

  Further, in this example, during the overlay period, the binocular shutter of the glasses is opened and the image can be viewed, and a brighter image can be seen as compared with the case of one eye, so that there is also an effect that the remote control operation becomes easier.

  Further, the configuration can be either hardware or software.

  In the above embodiment, three-dimensional glasses have been described as an example, but the invention of the present application is not limited to this. For example, it can also be configured in the case of a naked-eye type three-dimensional display device and a remote control device.

  In the description of the present embodiment, when the 3D image display device 1 displays the left-eye image of the 3D image, the binocular shutter of the 3D glasses 2 is opened and the right-eye image is displayed. However, the present invention is not limited to this combination. 3D image display device The binocular shutter of the 3D glasses 2 may be opened when displaying the right eye image of the 13D image, and closed when displaying the left eye image. .

(Embodiment 2)
The present embodiment will be described with reference to FIGS. FIG. 5 is a diagram showing a configuration of a 3D video display system. FIG. 6 is a flowchart illustrating an example of a control flow of the 3D video display system. FIG. 7 shows an image viewed by the viewer when the remote control infrared device 3 outputs a volume adjustment command and the 3D glasses 2 perform a shutter opening / closing operation for 2D images, as shown in the flowchart of FIG. It is a figure explaining the example of.

  The difference between the present embodiment and the first embodiment is that the two-dimensional one-eye open both-eye close shutter control unit 93 of the three-dimensional glasses 2 in FIG. 5 and the two-dimensional image processing shutter control (step 96) in FIG. It is the shutter opening and closing operation of FIG. In the present embodiment, differences from the first embodiment will be mainly described. Since the other points are the same as those in the first embodiment, the description thereof is omitted.

  The two-dimensional one-eye open both-eye close shutter control unit 93 of the three-dimensional glasses 2 in FIG. 5 superimposes a three-dimensional image, in this embodiment, a left-eye image and a two-dimensional display image such as volume control. Is different from the first embodiment in that only the shutter of one eye is opened and the shutter of the other eye is closed. Note that when the right-eye image of the three-dimensional image is displayed, the binocular shutter of the three-dimensional glasses 2 is closed as in the first embodiment.

  FIG. 6 is a control flowchart in the case of the 3D video display system shown in FIG. 6A is a control flowchart of the remote control infrared device 3, FIG. 6B is a control flowchart of the 3D video display device 1, and FIG. 6C is a control flowchart of the 3D glasses 2. In the first embodiment, as in the above description, when viewing a three-dimensional video, a video superimposed with a left-eye video and a two-dimensional display video such as volume adjustment in this embodiment, The difference is that only the shutter for one eye is opened and the shutter for the other eye is closed.

  FIG. 7 is a diagram for explaining the operation contents when the 3D video display device 1 and the 3D glasses 2 are used in the configuration shown in FIGS. 5 and 6. A viewer wearing the 3D glasses 2 opens only one eye so that the 3D image can be viewed with only the left eye (single eye) on which the 2D image is superimposed. Further, while the other image of the three-dimensional image is displayed, the shutters for both eyes are closed.

FIG. 8 is a timing chart showing an example of the operation of FIG.
The three-dimensional video display device 1 displays left-eye video, right-eye video, and left-eye video alternately in time. Similarly, the 3D video display device 1 displays the superimposed video alternately in time with the left eye video, the right eye video, and the left eye video. The left-eye shutter signal is ON only for the left-eye image, the right-eye shutter signal is OFF, and then the left-eye shutter signal is OFF for the right-eye image, and OFF when the right-eye shutter signal is also the right-eye image. It becomes a state. Thus, the only image that enters the left eye of the person is the left eye image, and no image enters the right eye of the person.

  In this way, when viewing a 3D image, when operating the remote control using 3D glasses, the depth plane is different between the original image and the overlaid superimpose screen such as the volume display menu, and the viewer feels uncomfortable. Thus, it is possible to improve the difficulty of remote control volume operation and the like.

  In this example, the volume operation of the remote control is described, but the same applies to other remote control operations. For example, the same applies to video adjustment, input terminal switching, channel display, and the like.

  The configuration can be either hardware or software.

  In the above embodiment, three-dimensional glasses have been described as an example, but the invention of the present application is not limited to this. For example, it can also be configured in the case of a naked-eye type three-dimensional display device and a remote control device.

  In the description of the present embodiment, when the 3D image display device 1 displays the left-eye image of the 3D image, only the one-eye shutter of the 3D glasses 2 is opened, and the right-eye image is displayed. In this case, the binocular shutter is closed, but the present invention is not limited to this combination. 3D image display device A device that opens only the one-eye shutter of the 3D glasses 2 when displaying the right-eye image of the 13-dimensional image, and closes the binocular shutter when displaying the left-eye image. It may be.

(Embodiment 3)
FIG. 9 is a diagram illustrating a configuration of a stereoscopic video system according to the present embodiment. The 3D video display apparatus 1 newly includes a 3D video data frame processing unit 68 and a 2D video frame timing correction unit 69, and conversely, the video data overlay continuation determination unit 13 and the glasses command continuation unit 14. The eyeglass command end unit 15 is different from the first embodiment in that it is deleted. The three-dimensional glasses 2 are different from those of the first embodiment in that the two-dimensional both-eyes simultaneous opening and simultaneous closing shutter control unit 23 is deleted.

  FIG. 10 shows a configuration of the stereoscopic video system shown in FIG. 9. The three-dimensional video display device 1 (FIG. 10A), the three-dimensional glasses 2 (FIG. 10B), and the remote control infrared light emitting device 3 (FIG. It is a flowchart which shows the control content of c)).

  The difference in control between the present embodiment and the first embodiment is that 3D video data frame editing (step 103) and 2D video frame timing correction (step 104) are added to FIG. 10B. And the processing of glasses command signal generation (step 47), conversion of electrical signals into optical signals (step 48), and glasses infrared signal emission (step 49), and FIG. ), The process of determining whether the command is a 3D video command or a 2D video command (step 64) and 2D video processing shutter control (step 66) is deleted. It is a point.

  The 3D video data frame editing (step 103) and the 2D video frame timing correction (step 104) perform processing for creating a 2D video from the 3D video. When performing these processes, a video suitable for a 2D video is generated from the 3D left and right video (step 103), and the generated video is appropriately displayed at the frame rate of the 2D video. As described above, the 3D video data frame processing unit 68 and the 2D video frame timing correcting unit 69 perform the process of correcting the frame timing (step 104).

  As shown in FIG. 10C, the 3D glasses 2 delete the shutter control of the 2D video from the processing and perform the control of only the 3D video. Therefore, the 3D glasses 2 only perform an operation of viewing 3D video.

  FIG. 11 shows the relationship between the image displayed on the 3D image display device 1 when the control is performed, the operation of the 3D glasses 2, and the image viewed by the viewer. is there. The right-eye 3D video 114 is a video that has been frame-edited by the 3D video data frame processing unit 101 and the 2D video frame timing correction unit 702 from the left-eye 3D video 113. As a result, the video displayed by the 3D video display device 1 becomes a 2D data video with smooth movement. Since the left-eye superimposing image 75 and the right-eye superimposing image 76 are not three-dimensionalized, both are the same image. The eyeglass shutter unit opens the left-eye shutter 76 for the left-eye three-dimensional image 72, and conversely opens the right-eye shutter 77 for the right-eye three-dimensional image 73. An image 78 entering the viewer's left eye is a left-eye 3D image 72 and a left-eye superimposition image 74, and an image 79 entering the viewer's right eye is frame-edited from the left-eye image 72. The created two-dimensional image 73 and the superimpose image 75 for the right eye. As a result, the video displayed by the three-dimensional video display device 1 enters the viewer's eyes through the three-dimensional glasses 2, so that the volume and the volume display unit do not shake from side to side.

  FIG. 12 is a timing diagram illustrating the operation example of FIG. 11. The 3D video display device 1 displays a left-eye video, a frame-edited left video, and a left-eye video alternately in time. The superimpose image is displayed alternately in time with the left eye image, the right eye image, and the left eye image. The left-eye shutter signal is turned on when the left-eye image is on, the right-eye shutter signal is turned off, and then the left-eye shutter signal is turned off when the frame-edited left-eye image is on and the right-eye shutter signal is turned on. Become. In this way, the left eye image enters the human left eye, and the frame-edited left eye image enters the human right eye. The N + 1 frame performs the same operation as the N frame.

  In this way, when viewing a 3D image, when operating the remote control using 3D glasses, the depth plane is different between the original image and the overlaid superimpose screen such as the volume display menu, and the viewer feels uncomfortable. Thus, it is possible to improve the difficulty of remote control volume operation and the like.

  In this example, the volume operation of the remote control is described, but the same applies to other remote control operations. For example, the same applies to video adjustment, input terminal switching, channel display, and the like.

  The configuration can be either hardware or software.

  In the above embodiment, three-dimensional glasses have been described as an example, but the invention of the present application is not limited to this. For example, it can also be configured in the case of a naked-eye type three-dimensional display device and a remote control device.

  In the description of the present embodiment, the description has been given using the example in which the video displayed by the 3D video display device 1 for the right eye is processed from the left eye, but the description is not limited thereto. The video for the right eye may be edited and processed from the left eye.

(Embodiment 4)
FIG. 13 is a configuration diagram of a stereoscopic video system described in the present embodiment. The 3D video display apparatus 1 is different from the first embodiment in that a 3D video data frame processing unit 68 and a 2D video frame timing correction unit 69 are newly provided. In the description of the present embodiment, differences from the first embodiment will be mainly described.

  Since the 3D video data frame processing unit 68 and the 2D video frame timing correction unit 69 are the same as those described in the third embodiment, description thereof will be omitted.

  14 shows the remote control infrared device 3 (FIG. 14A), the three-dimensional video display device 1 (FIG. 14B), and the three-dimensional glasses 2 (FIG. 14C) in the system configuration of FIG. It is a flowchart which shows control. Since the control of the remote control infrared device 3 is the same as in the first embodiment, the description thereof is omitted. In addition to the control flow described in the first embodiment, the control of the 3D video display apparatus 1 includes the 3D video data frame editing (step 103) and the 2D video frame timing correction (step 103) described in the third embodiment. 104) is added. Since the control of the three-dimensional glasses 2 is the same as the control content described in the first embodiment, the description thereof is omitted.

  FIG. 15 is a diagram illustrating a relationship among the 3D video display device 1, the 3D glasses 2, and the video viewed by the viewer. In the N frame, the left-eye three-dimensional image 113 is the right-eye three-dimensional image 114, and the three-dimensional image data frame processing unit 101 and the two-dimensional image frame timing from the three-dimensional image 113 for the left eye. The data is converted into two-dimensional data adjusted by the correction unit 102 and smoothed in movement. The superimposing video 75 for the left eye and the superimposing video 76 for the right eye are not the same as the three-dimensional video. The eyeglass shutter unit 24 opens the binocular shutter on the left-eye three-dimensional image 113, and also opens the binocular shutter on the right-eye three-dimensional image 114. As a result, the left-eye image and the superimpose image enter the viewer's eyes through the three-dimensional glasses 2, so that the volume and the volume display unit do not shake from side to side.

  FIG. 16 shows the operation example of FIG. 15 in a timing diagram. The image of the three-dimensional image display apparatus 1 is alternately displayed in time with the left-eye image, the frame-edited left-eye image, and the left-eye image. . The superimpose image is displayed alternately in time with the left eye image, the right eye image, and the left eye image. The left-eye shutter signal is ON when the left-eye image is edited with the left-eye image frame, and the right-eye shutter signal is also ON. Next, the left-eye shutter signal is ON when the frame is edited with the left-eye image, right The eye shutter signal is also turned on. In this way, the left eye image and the frame-edited left eye image enter the human left eye, and the same image also enters the human right eye. The N + 1 frame performs the same operation as the N frame.

  In this way, when viewing a 3D image, when operating the remote control using 3D glasses, the depth plane is different between the original image and the overlaid superimpose screen such as the volume display menu, and the viewer feels uncomfortable. Thus, it is possible to improve the difficulty of remote control volume operation and the like.

  In this example, the volume operation of the remote control is described, but the same applies to other remote control operations. For example, the same applies to video adjustment, input terminal switching, channel display, and the like.

  In this example, during the overlay period, the glasses can be viewed with the binocular shutter open, and a brighter image can be seen as compared with the case of one eye. The configuration can be either hardware or software.

  In the above embodiment, the stereoscopic video viewing glasses have been described as an example, but the invention of the present application is not limited to this. For example, it can also be configured in the case of a naked-eye type three-dimensional display device and a remote control device.

  In the above description, the case where a frame-edited video is generated from the left-eye video has been described as an example, but the description of the present embodiment is not limited to this. An image obtained by frame editing from the right eye image may be displayed as the left eye image.

  The stereoscopic image viewing glasses and the control method thereof according to the present application can be used for devices for displaying and viewing stereoscopic images.
