Description

  The present invention relates to a video display device and a control method thereof, and in particular, performs video processing for 3D display on a 3D video output from a video playback device that outputs a 3D video connected to the video display device. The present invention relates to a video display device capable of displaying a 3D video and a control method thereof.

  Currently, the BS11 channel of Japanese digital satellite broadcasting adopts the “Side-by-Side” system in which video signals for the right eye and left eye are horizontally compressed and halved in the horizontal direction. 3D video content (hereinafter referred to as 3D content) is broadcast. Recently, Blu-ray discs that record 3D content have also been released.

  In order to view 3D content by the side-by-side method, a dedicated 3D video display device (hereinafter referred to as 3D television) and polarized glasses suitable for 3D television are required.

  In a 3D television compatible with the side-by-side method, images having binocular parallax are horizontally expanded, and a left-eye image is assigned to an odd-numbered line on a television screen, and a right-eye image is assigned to an even-numbered line for display. . The user sees the output image of the 3D television through the polarized glasses, so that the user sees the image as a stereoscopic image.

  In the future, with the widespread use of viewing environments for 3D content, it is expected that not only on-air viewing but also opportunities to view 3D content recorded by video playback devices such as HDD recorders and players connected to a 3D television will increase. That is, it is conceivable that the number of 3D televisions that switch between the display of conventional 2D video content (hereinafter referred to as 2D content) and the display of 3D content will increase.

  As a technique for switching between 2D content and 3D content for display, a method has been proposed in which identification metadata for identifying 3D content is embedded in a specific area of image data and the display method is switched based on the metadata. (See Patent Document 1).

  In addition, in a multi-layer disc, a method has been proposed in which a left-eye image is recorded on one layer and a right-eye image is recorded on the other layer, and both layers are alternately read out to be 3D during playback from the disc ( Patent Document 2).

  However, in the side-by-side method, an image is divided in the horizontal direction so as to be divided into left-eye and right-eye images, and then each image is enlarged and displayed in the horizontal direction. Therefore, when a two-dimensional OSD (On Screen Display) graphics image superimposed on 3D video by the playback device is displayed on the 3D television side, there is a problem that the video becomes very difficult to view.

  FIG. 8 shows an example (a) of the output image of the video reproduction apparatus and an example (b) of the output image when the output image is processed by the 3D television by the above-described method.

  When an operation from the user occurs while the content is being played back by the video playback device, a general playback device outputs a video in which an OSD image corresponding to the operation is superimposed and synthesized on the video being played back. Well-known information to be displayed includes an icon indicating a state such as reproduction or pause, a banner for displaying content information, a content list indicating a list of content, and the like. If the content being reproduced is 2D content, the user can appropriately visually recognize the OSD regardless of what OSD is combined. However, if the content being played back is 3D content, video processing adapted to the side-by-side method is performed on the output video on the 3D television side, and the OSD image portion is expanded in the horizontal direction. Display an image with low visibility that is difficult to see. This state is shown in FIG. The original video part is displayed as 3D video by video processing adapted to the side-by-side method. However, when an OSD image similar to 2D content is synthesized without considering video processing of 3D content, it looks like this as an example It becomes.

  As a result, there is a problem that the OSD image superimposed by the playback device is displayed to the user as a video that is difficult to view at a position different from the original drawing position. By performing such a display, it is assumed that the playback device or the 3D TV is mistaken for a failure, and if the user wants to clearly see the OSD image, the user performs a 3D display canceling operation, etc. Will be bothered.

  In the present invention, when a video playback device that plays back 3D content displays an OSD image in a superimposed manner, the video can be appropriately displayed by switching to the 2D display mode automatically. An object is to provide a display device and a control method thereof.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 shows an example of a system configuration in the present invention. Reference numeral 101 denotes a 3D television as a video display device. The 3D television can appropriately display 2D content, and has a function of outputting the above-described side-by-side 3D content as 3D video.

  Reference numeral 103 denotes a remote controller for operating the 3D television. In addition to the function of operating the 3D television 101, the remote controller 103 also has a function of operating the video playback device 102 via the 3D television. The remote controller 103 includes a button for switching between 2D display and 3D display. When the user presses this button, the 3D television 101 receives an instruction by button operation. The 3D television 101 does not execute the 3D display mode (3D display mode) using the images for the left eye and the right eye and the 3D video processing, that is, the 2D for displaying a normal 2D image. Switch the display mode (2D display mode). That is, the 3D television 101 switches between 3D video processing (three-dimensional video processing) and 2D video processing (two-dimensional video processing) according to a user instruction.

  The video playback device 102 has a built-in recording / playback drive for a removable disk such as a hard disk or a Blu-ray disk. It is assumed that 3D content is stored on a hard disk or a removable disk. Any storage method may be used. For example, a method of recording 3D content being broadcast is used.

  When reproducing the stored 3D content, the user instructs the 3D television 101 to reproduce the content using the remote controller 103. The 3D television 101 transmits a playback instruction for the received content to the video playback device 102. The video playback device 102 reads out and plays back from the disc storing the 3D content for which the playback instruction has been received.

  The 3D television 101 and the video playback device 102 are connected by a digital interface 104 typified by HDMI (High-Definition Multimedia Interface). In HDMI, control commands can be transmitted and received in addition to video data and audio data.

  Specifically, operations between devices such as content playback and recording, content list and device information acquisition are applied by applying a standard that defines operation commands between home appliances called HDMI-CEC (Consumer Electronics Control). I do. This CEC allows the user to operate the video playback device 102 in accordance with an instruction for operating the video playback device 102 input to the 3D television 101 via the remote controller 103.

  In this embodiment, a configuration using an HDMI cable is taken as an example, but the present invention can be similarly applied to other wired or wireless interfaces, and is not particularly limited.

  Next, the details of the 3D television 101 will be described with reference to the block diagram shown in FIG. Each processing block constituting the 3D television 101 is connected to a system bus, and commands and data are communicated between the blocks via the bus.

  The DRAM 201 is a volatile large-capacity semiconductor memory, and is a storage unit that stores output data from each block described later, such as an encoded stream, decoded image data, or audio data.

  The remote control light receiving unit 202 receives a signal such as an infrared ray transmitted from the remote control 103 by a user operation, and notifies the CPU 203 that an operation command corresponding to the signal has occurred. The CPU 203 is a microcomputer that controls each block constituting the 3D television 101. A read-only ROM 204 and a readable / writable RAM 205 are connected to the CPU 203, and programs and data for operating the CPU 203 are stored. In addition, when the video is displayed on the 3D television 101, the CPU 203 manages whether the display is performed in the 2D display mode or the 3D display mode.

  The video processing unit 207 is a block that performs various video processing on video displayed on the 3D television 101. In particular, in the 3D display mode for displaying 3D video, the block performs 3D video processing for overlapping the left-eye image and the right-eye image input in a side-by-side manner.

  The tuner demodulation unit 208 is a block that demodulates a digital broadcast wave received from an antenna (not shown). The tuner demodulation unit 208 outputs time-division multiplexed TS data including video / audio information for a desired channel. The decoding unit 209 separates the TS data generated by the tuner demodulation unit 208 into video and audio ESs, and decodes the ES data. The video data decoded by the decoding unit 209 and the video data input from the video reproduction device 102 are transmitted to the video processing unit 207 and subjected to appropriate video processing.

  The video output unit 210 is a block that outputs video data processed by the video processing unit 207 to a display panel (not shown). The video output unit 210 also has a function of generating an OSD image under the control of the CPU 203 and superimposing (combining) the generated OSD image on video data.

  The digital interface control unit 211 is an HDMI interface connected to the video playback device 102. The digital interface control unit 211 has a function of transmitting a command to be transmitted to the video playback apparatus 102 in a format stipulated by the interface standard by a user's remote control operation. Further, it has a function of receiving video data output from the video playback device 102 and transmitting it to the bus.

  When receiving and viewing 3D content included in a broadcast wave, the 3D television 101 demodulates the TS of the side-by-side 3D content received by the tuner demodulation unit 208 and decodes it by the decoding unit 209.

  At this time, when the user inputs an instruction indicating a transition to a 3D display mode in which 3D video is displayed using the remote controller 103, the CPU 203 that has received this instruction performs 3D video processing on the video data decoded by the decoding unit 209. The video processing unit 207 is instructed to perform the above. The video processing unit 207 performs 3D video processing processing conforming to the side-by-side method on the input video data. The video data that has been subjected to the 3D video processing is output to the display panel under the control of the video output unit 210.

  On the other hand, when viewing 3D content transmitted from the video playback device 102, the user inputs an operation instruction for playing back 3D video using the remote controller 103. In accordance with the input instruction, the CPU 203 exchanges information such as transmitting a command to the video playback device 102 and receiving a command from the video playback device 102.

  The video data of the 3D content transmitted by the video playback device 102 is received by the digital interface control unit 211 and subjected to 3D video processing by the video processing unit 207. The video data that has undergone the 3D video processing is output to the display panel under the control of the video output unit 210.

  Next, the operation flow in the present invention will be described with reference to the flowchart shown in FIG. This flowchart is control executed by the 3D television 101 in a state where the 3D content being played back by the video playback device 102 is displayed on the 3D television 101.

  In the 3D television 101, the remote control light receiving unit 202 constantly monitors the presence or absence of a remote control operation from the user (step S301). When the remote control light receiving unit 202 detects that a remote control operation has been performed, an operation command instructed by the remote control operation is acquired and notified to the CPU 203 (step S302).

  The CPU 203 interprets the received operation command and determines whether the command is a command that needs to control the video playback device 102 (step S303). If the command needs to control the video playback device 102, the process proceeds to step S404. If the received operation command is a command that does not need to control the video playback device 102, the process proceeds to step S309.

  In step S304, the CPU 203 determines whether to display an OSD image instead of the video being reproduced or superimposed on the video being reproduced as a response of the video reproduction device 102 to the command.

  For example, a command for requesting display of content list information recorded in the video playback device 102, a command for requesting acquisition of various information of the video playback device 102, a command for operating content being played back, etc. In this case, the video reproduction device 102 generates an OSD image.

  In this embodiment, for a plurality of commands that can be issued to control the video reproduction device 102, information regarding whether the video reproduction device 102 displays an OSD image by the command is managed. This ODS display information is stored in advance in an arbitrary memory such as the ROM 204 of the 3D television 101. The CPU 203 uses the OSD display information to execute the determination in step S304.

  In step S304, if the CPU 203 determines that the command is for displaying an OSD image, the process proceeds to step S305. If the CPU 203 determines that the command is for displaying an OSD image, the process proceeds to step S310.

  In step S305, the CPU 203 confirms whether the current 3D television is in the 2D display mode or the 3D display mode. Since the display mode switching control is executed by the CPU 203, the CPU 203 can make a determination by using display mode information managed by the CPU 203 itself.

  In step S306, when the CPU 203 determines that the current display mode is the 3D display mode, the process proceeds to step S307. If the current display mode is other than the 3D display mode, that is, the 2D display mode, the process proceeds to step S309.

  Through the processing up to step S306, the user is currently viewing the 3D content being played back by the video playback device 102 in the 3D display mode, and issues a command accompanying OSD image display to the video playback device 102. It can be determined that this is the state. If an OSD image is displayed in this state, the same video display as described in the background art is performed, and naturally the same problem occurs.

  Therefore, in the next step S307, the CPU 203 instructs the video processing unit 207 to automatically switch the display mode from the 3D display mode to the 2D display mode so that the OSD image can be appropriately displayed. The video processing unit 207 stops the 3D video processing in accordance with an instruction from the CPU 203 and applies the 2D video processing to the video transmitted from the video playback device 102. Thus, even when the video playback device 102 outputs 3D content, the 3D display is temporarily changed to 2D, but the OSD image can be appropriately displayed.

  The CPU 203 stores, as mode switching information, that the reason for switching from the 3D display mode to the 2D display mode is based on the display of the OSD image. This is information used for processing when returning from the 2D display mode to the 3D display mode, which will be described later.

  In step S308, the CPU 203 instructs the video output unit 210 to notify that the display mode has been automatically switched. The video output unit 210 outputs a video obtained by synthesizing a message indicating that the display mode has been automatically switched to the video transmitted from the video playback device 102 by displaying the OSD image to the display panel. As a result, the user can recognize that switching to 2D display has been performed by performing an operation involving OSD display, and can recognize that this is not a problem with the television or the video playback device.

  Subsequently, in step S309, the CPU 203 executes control according to the received operation command. If this operation command is to control the video playback device 102, the command is issued to the video playback device 102. For example, in the case of a command for requesting display of a content list screen recorded by the video playback device 102, the CPU 203 issues a command for requesting display of the content list screen to the video playback device 102.

  Note that the command to be transmitted to the video playback device 102 is obtained by converting a remote control operation command into a command format compliant with the HDMI standard (in the present invention, a format defined by HDMI-CEC).

  In response to the command received from the 3D television 101, the video playback device 102 generates an OSD image that displays a content list screen, superimposes it on the video of the 3D content being played, and transmits it to the 3D television 101. Since the 3D television 101 is in the 2D display mode at this time, it is possible to prevent the OSD image from being in an inappropriate state due to the 3D video processing. Further, since the video playback device 102 can generate a normal OSD image without being conscious of the type of content such as 3D or 2D, the device configuration can be simplified.

  Next, a process when returning to the 3D display mode after executing the control flow described above will be described. In other words, this processing is performed after the video playback device 102 plays 3D content and the 3D content is displayed on the 3D television in the 3D display mode, and then switches to the 2D display mode in accordance with the display of the OSD image. Applied. Then, when an OSD image is displayed, an operation command input from the user via the remote controller 103 is executed as a trigger.

  First, steps S301 to S304 are the same as the above-described flow, and thus description thereof is omitted.

  If the CPU 203 determines in step S304 that the command does not display an OSD image, the process proceeds to step S310. In step S310, the CPU 203 determines whether the command is an end command for canceling the display of the currently displayed OSD image. This determination is made using the managed OSD display information and the operation command acquired in S302.

  Examples of the operation that triggers the end command include an operation that cancels the current state, such as pressing a cancel button on the remote control 103 or pressing a return button. In this embodiment, it is assumed that an operation that can specify an end process for a command currently being executed on the video playback apparatus 102 is handled.

  If the CPU 203 determines in step S310 that the command is an end command, the process proceeds to step S311. If it is determined that the command is other than an end command, the process proceeds to step S309 and the command is executed as it is.

  In step S311, the CPU 203 refers to the mode switching information stored in the ROM 204 in step S307, and whether or not the current display mode (2D display mode) is switched from the 3D display mode to display the OSD image. Judging.

  If it is determined in step S311 that the 3D display mode has been switched to display the OSD image, the CPU 203 advances the process to step S312. Otherwise, for example, when an OSD is displayed while 2D content is being displayed, it is simply an end command for ending the display of the OSD image, so the process proceeds to step S309 and processing corresponding to the command is executed. To do.

  If it is determined in step S311 that the control for automatically switching to the 2D display mode has been executed for displaying the OSD image, the CPU 203 transmits an end command to the video reproduction device 102 via the digital interface control unit 211. To do. Receiving the end command, the video playback device 102 executes control for hiding the OSD image being displayed.

  In step S313, the CPU 203 instructs the video processing unit 207 to perform 3D video processing on the video received from the video playback device 102. That is, the control for automatically switching from the 2D display mode to the 3D display mode is executed. Further, in step S314, as in step S308, in order to notify the user that the mode has been switched to the 3D display mode, the CPU 203 performs control so that the message is combined with the video output to the display panel and displayed. At this time, since the displayed video is a 3D video, it is necessary to synthesize the message to be displayed with the video after the 3D video processing. This is because if 3D video processing is performed before 3D video processing, 3D video processing is also applied to the message, making visual recognition difficult.

  FIG. 4 is a diagram illustrating an example of an image displayed on the display panel when the above-described flow is executed. FIG. 4A shows a state in which 3D video obtained by performing 3D video processing on the 3D content played back by the video playback device 102 is displayed on the display panel. In this state, when display of the OSD image of the video playback device 102 is requested by a user operation, a video as shown in FIG. 4B is displayed on the display panel. This is a state in which the 3D video processing for the 3D content is interrupted and the mode is automatically switched to the 2D display mode so that the OSD image is appropriately displayed. When an operation for hiding the OSD image is performed by the user, a command for hiding the OSD image is transmitted to the video reproduction device 102. Thereby, the OSD image displayed in the state of FIG. 4B is not displayed. Further, since the 2D display mode is switched to the 3D display mode, 3D video is displayed again on the display panel.

  As described above, the 3D television 101 according to the present embodiment automatically controls switching between the 3D display mode and the 2D display mode so that the OSD image is appropriately displayed when an instruction to display the OSD image is given by the user. Execute.

  As a result, when the video playback device 102 that is playing back 3D content displays the OSD image in a superimposed manner, the OSD image can be appropriately displayed by automatically switching to the 2D display mode. A television 101 can be provided.

  In addition, since the 2D display mode and the 3D display mode are automatically switched according to the user's operation relating to display and non-display of the OSD image, the user does not need to manually switch the display mode separately, and the operability is improved.

  Subsequently, a second embodiment of the present invention will be described. In the first embodiment, when the video playback device 102 outputs an OSD image, the 3D television 101 performs control to switch the display mode from the 3D display mode to the 2D display mode. On the other hand, in this embodiment, instead of switching the 3D display mode to the 2D display mode for displaying all the OSD images, the display mode switching is controlled according to the type of the OSD image while displaying the video in the 3D display mode. It is.

  Hereinafter, the present embodiment will be described with reference to the drawings. The description of the same blocks and flowchart steps as those in the first embodiment is omitted.

  FIG. 5 shows the configuration of the OSD display information used in this embodiment. In the first embodiment, OSD display information that manages whether or not an OSD image corresponding to an operation executed by the video reproduction apparatus 102 is displayed is stored in advance. On the other hand, in this embodiment, OSD display information that defines whether the display mode is switched to the 2D display mode or remains in the 3D display mode is used for each command, that is, for each type of OSD image.

  FIG. 5 defines whether to keep the 3D display mode or switch to the 2D display mode for each control command for displaying the OSD image that is transmitted from the 3D television 101 to the video reproduction device 102. This is OSD display information.

  In the OSD display information shown in FIG. 5, the control command for switching to the 2D display mode is determined according to the area (OSD image size) occupied by the OSD image (displayed video), the display position, and the content.

  For example, for a control command for displaying EPG, ContentsMenu, etc., the video playback device 102 superimposes an OSD image on the entire screen and displays character information in response to the command. Switch from mode to 2D display mode.

  On the other hand, for control commands related to operations during playback, such as Pause, Forward, and VolumeUp, the area occupied by the OSD image is generally small and the display position is often at the screen edge. Further, there is almost no display of character information, and icons are generally displayed. Even when such an OSD image is displayed, if the 3D display is automatically converted to the 2D display, there is a high possibility that the user's viewing of the 3D video is hindered. Therefore, when displaying such an OSD image, it is better to continue displaying the 3D video as it is without switching to the 2D display mode.

  The command for switching to the 2D display mode may be arbitrarily determined from the command in advance and the OSD image of the video playback device. Moreover, it is good also as a structure which can be arbitrarily set by the user.

  FIG. 6 shows a flowchart applied to this embodiment. This flowchart is control executed by the 3D television 101 in a state where the 3D content being played back by the video playback device 102 is displayed by performing 3D video processing on the 3D television 101.

  Steps S601 to S603 are the same as steps S301 to S303 in the first embodiment, and a description thereof will be omitted.

  In step S604, the CPU 203 refers to the OSD display information shown in FIG. In step S605, the CPU 203 determines whether the command that needs to be controlled by the video playback device 102 in step S603 is a command that displays the OSD and needs to be switched to the 2D display mode. This determination can be performed by comparing the OSD display information referenced in step S604 with the control command corresponding to the input operation command. If it is determined in step S605 that the command requires switching to the 2D display mode, the process proceeds to step S606.

  Since step S606 is a step corresponding to step S305 of the first embodiment, the description thereof is omitted. Also, steps S607 to S615 are steps corresponding to steps S306 to S314, and thus description thereof is omitted. The above is the operation flow of the second embodiment.

  As described above, the 3D television 101 of this embodiment has OSD display information that predefines whether or not to switch to the 2D display mode for each control command for controlling the video playback device 102. It is determined whether or not to switch the display mode.

  Thus, when the video playback device 102 playing back 3D content displays an OSD image superimposed on the 3D content, the video playback device 102 switches to the 2D display mode depending on the type of the OSD image. Alternatively, by selecting to maintain the 3D display mode, it is possible to provide a 3D television that achieves both proper display of OSD images and suppression of 3D content viewing as much as possible.

  Subsequently, a third embodiment of the present invention will be described. In the first and second embodiments, when the video reproduction device 102 outputs an OSD image, the 3D television 101 performs control to switch the display mode. In addition, the 3D television 101 controls the video playback device 102 during display of 3D content. On the other hand, the present embodiment considers a case where the user directly controls the video playback device 102 using a remote control attached to the video playback device 102 instead of controlling the video playback device 102 via the 3D television 101. To do. That is, the present embodiment relates to a case where an OSD image is displayed or superimposed during playback of 3D content by a user inputting an instruction to the video playback device 102 without going through the 3D television 101.

  Hereinafter, the present embodiment will be described with reference to the drawings. The description of the same blocks and flowchart steps as those in the first and second embodiments is omitted.

  FIG. 7 shows a flowchart applied to this embodiment. This flowchart is control executed by the 3D television 101 in a state where the 3D content being played back by the video playback device 102 is displayed on the 3D television 101.

  First, in step S <b> 701, the CPU 203 of the 3D television 101 periodically acquires status information of the connected video playback device 102 via the digital interface control unit 211. This status information is information indicating various states that the video reproduction apparatus 102 can take. Accordingly, in addition to control of the video being played back by the video playback device 102, the CPU 203 also acquires status information such as display of an EPG and display of a menu screen.

  In order to acquire the status information, the 3D television 101 periodically polls the video playback device 102. There is no restriction on the polling period, but it is desirable that the period be as short as possible.

  In step S702, the video playback apparatus 102 transmits and analyzes the acquired status information, and determines whether or not the OSD image is currently displayed in the video playback apparatus 102. This determination is executed by the CPU 203 referring to the OSD display information and comparing with the status information. Note that, in the OSD display information in this embodiment, information related to the presence / absence of OSD image display is managed in advance in association with the status information of the video playback device 102.

  When the CPU 203 determines that the OSD image is displayed in step S702, in step S703, information indicating whether the current display mode of the 3D television 101 is the 2D display mode or the 3D display mode is acquired. The process proceeds to S704.

  In step S704, when the CPU 203 determines that the 3D display mode is selected, the CPU 203 issues an instruction to the video processing unit 207 to switch to the 2D display mode, and the video processing unit 207 performs the 2D display from the 3D video processing. Switch video processing to video processing.

  Since step S706 is a step corresponding to step S308 of the first embodiment, the description thereof is omitted. Step S707 is a step corresponding to step S311, and steps S708 to S709 are steps corresponding to steps S313 to S314.

  The control flow described above assumes a case in which the video playback apparatus 102 is directly operated in the configuration of the first embodiment. However, this embodiment can also be applied to the configuration of the second embodiment. Even if the status information acquired in step S701 is status information indicating the display of the OSD image, by referring to the OSD display information that determines in advance whether or not to switch the 2D display depending on the display content and the size of the occupied area. It is possible to maintain the 3D display mode.

  As described above, the 3D television 101 according to the present embodiment periodically acquires and analyzes the status information of the video playback device 102 even when the video playback device 102 is directly operated, thereby determining whether or not the OSD image is displayed. to decide. When the OSD image is being displayed, control is performed to automatically switch to the 2D display mode in accordance with predetermined OSD display information.

  Thereby, even when the video reproduction apparatus 102 is directly operated, the 3D television 101 capable of appropriately displaying an OSD image can be provided by automatically switching to the 2D display mode.

  In the third embodiment described above, the 3D television 101 is configured to recognize the OSD display state of the video playback device 102 by periodically acquiring status information from the video playback device 102. However, in the third embodiment, it is also possible to adopt a configuration in which the 3D television 101 does not periodically acquire status information, but the video playback device 102 actively transmits the status state to the 3D television 101. is there. In the video playback device 102, when an OSD image is to be displayed, a command indicating that the OSD image is displayed is transmitted to the 3D television 101 as status information. Of course, the OSD image type can also be transmitted. When the transmission means is HDMI, it is preferable to transmit status information to the 3D television 101 using CEC. As a result, the 3D television 101 can acquire information for determining whether or not the OSD is displayed, in the same manner as the 3D television 101 periodically polls and acquires the status information.

  In the above, three examples in the case where the present invention is implemented have been described, but the present invention is not limited to the side-by-side video display device. Any method may be used as long as it is a three-dimensional display method for performing 3D display by changing the input 3D video image in the spatial direction. Changing in the spatial direction is processing such as dividing or enlarging an image constituting a 3D video image or replacing scanning lines.
