Description

  Embodiments described herein relate generally to an information processing apparatus, an information processing method, and a program for displaying a 3D video.

  In recent years, various video display devices for viewing 3D video have been provided. As one of such video display devices, there is a video display device based on an autostereoscopic system (naked eye 3D system). In the autostereoscopic method, for example, a left-eye image and a right-eye image are simultaneously displayed on a liquid crystal display (LCD) (space division method), and a vertical lenticular lens disposed on the LCD is used to The direction in which the light beam corresponding to the pixel is emitted is controlled (lenticular method). Accordingly, the user can perceive a 3D video (stereoscopic video) because the pixel of the left eye video can be viewed with the left eye and the pixel of the right eye video can be viewed with the right eye.

  As an example of the 3D video, there is a video recorded on an optical disc such as a DVD or a Blu-ray Disc (registered trademark). The optical disc is reproduced not only by a dedicated reproduction-only device / recording / reproduction device but also by a personal computer having a disc reproduction program. In the case of reproduction by a dedicated device, the 3D video read from the optical disk is displayed on the entire LCD screen. However, some optical disks do not record 3D video, but only 2D video. Therefore, the lenticular lens placed on the LCD consists of a liquid crystal gradient index lens (a lens that forms a refractive index distribution with electrodes using flat liquid crystal) that can electrically switch the lens functions necessary for 3D image display. It is possible to switch between original video display and two-dimensional video display.

  On the other hand, when an optical disk is played back by a personal computer, a playback program window is displayed on a part of the LCD screen, a 3D image is displayed on the window, and a desktop screen other than the window or another window is displayed. Two-dimensional video display may be displayed. Therefore, the liquid crystal gradient index lens can change the position and size of the 3D video display area by partially controlling the electrodes.

  When a 3D image is displayed using a playback program of a personal computer, when an operation for displaying a menu screen of the playback program is performed or another application program is started, another window is displayed on the screen. Depending on the position and size of the 3D video display window, another window may be displayed overlapping the 3D video display window. Alternatively, although not initially overlapping, when the user performs an operation of moving the position of another window or an operation of changing the size, another window may overlap the 3D video display window. In the 3D video display window on the lower side of another window, the left-eye video and the right-eye video are partially missing. In the autostereoscopic method, the condition is that the left-eye image pixel is viewed by the left eye and the right-eye image pixel is viewed by the right eye. In such a case, the stereoscopic image cannot be perceived.

  An object of the present invention is to provide an information processing apparatus, an information processing method, and a program that do not hinder even if another video display area overlaps a 3D video display area.

  According to the embodiment, the information processing apparatus includes a display unit capable of partially switching between two-dimensional display and three-dimensional display, and display means for displaying video in the first area and the second area of the display screen of the display unit. And detecting means for detecting an overlap between at least a part of the first region and the second region. When the detection means does not detect the overlap between at least a part of the first area and the second area, the display means displays the image in a three-dimensional manner in the first area, and the detection means detects at least a part of the first area and the second area. When the overlap is detected, the display means displays the image two-dimensionally in the first area.

Hereinafter, embodiments will be described with reference to the drawings.
FIG. 1 is a perspective view illustrating an appearance of an information processing apparatus according to an embodiment. The information processing apparatus is realized as, for example, a notebook type personal computer 1. However, the information processing apparatus is used as another device such as a television receiver, a recorder for storing video data (for example, a hard disk recorder, a DVD recorder), a tablet PC, a slate PC, a PDA, a car navigation device, a smartphone, or the like. Can also be realized.

As shown in FIG. 1, the personal computer 1 includes a computer main body 2 and a display unit 3.
A three-dimensional display (3D display) 15 is incorporated in the display unit 3. The display unit 3 is attached to the computer main body 2 so as to be rotatable between an open position where the upper surface of the computer main body 2 is exposed and a closed position covering the upper surface of the computer main body 2. The 3D display 15 includes an LCD (liquid crystal display) 15A and a lens unit 15B.

  The principle of 3D video display is to display a plurality of videos with different positions and angles at the same time according to the viewing position. It is based on the autostereoscopic method that can recognize For this reason, images having a plurality of parallaxes are simultaneously drawn on the LCD 15A, images in a plurality of directions are displayed by one pixel, and light from the pixels is emitted in a plurality of directions by a lens unit 15B having a vertical lenticular lens function.

  The lens unit 15B made of a flat liquid crystal layer is affixed on the LCD 15A. The lens unit 15B is, for example, a liquid crystal gradient index (GRIN) lens that can electrically switch functions necessary for 3D image display. In this liquid crystal GRIN lens, the refractive index distribution is created by the voltage applied to the electrodes, so that, for example, 3D image display can be performed in a certain area in the screen, and 2D image display can be performed in another area. In other words, by changing the refractive index of the lens between the 3D video display area and the 2D video display area, a 3D display mode for 3D video display and a 2D display mode for 2D video display are provided. It is possible to switch partially within the screen of the 3D display 15. The positions and sizes of the 3D video display area and the 2D video display area can be freely set. In the region set to the three-dimensional display mode, the image displayed in the region and the image observed with the left eye and the image observed with the right eye have parallax according to the interocular distance, viewing distance, etc. The refractive index is controlled. In the region set to the two-dimensional display mode, the refractive index is controlled so that the image displayed in the region is displayed as it is without being refracted. As described above, in the 3D display 15, each of a plurality of regions having an arbitrary position and size set in the screen can be set to one of the 3D display mode and the 2D display mode.

  The 3D display 15 displays a composite video (also referred to as parallax video data) including a left-eye video and a right-eye video in the 3D display mode area, and displays a 2D video in the 2D display mode area. Therefore, the user perceives 3D video (stereoscopic video) when viewing the area set in the 3D display mode on the screen, and perceives 2D video when viewing the area set in the 2D display mode. be able to.

  On the right side of the computer body 2, for example, an antenna terminal 30A for TV broadcasting is provided. Further, an external display connection terminal corresponding to, for example, the HDMI (high-definition multimedia interface) standard is provided on the back surface of the computer main body 2, for example. The external display connection terminal is used to output video data (moving image data) included in video content data such as broadcast program data to an external display.

FIG. 2 is a diagram showing a system configuration of the computer 1.

  The CPU 11 is a processor that controls the operation of the computer 1. The CPU 11 executes application programs such as an operating system (OS) 13A and a video content reproduction program 13B that are loaded from the HDD 21 to the main memory 13. The video content reproduction program 13B is software having a function for viewing video content data. The video content reproduction program 13B is a live reproduction process for viewing broadcast program data received by the TV tuner 30, a recording process for recording the received broadcast program data in the HDD 21, and a broadcast program data / data recorded in the HDD 21.

  Furthermore, the video content reproduction program 13B also has a function for viewing 3D video. The video content reproduction program 13B can also convert the 2D video included in the video content data into a 3D video in real time (2D-3D conversion) and display it on the screen (3D display screen) 15. The video content reproduction program 13B can perform 2D-3D conversion of various video content data (for example, broadcast program data, video data stored in a storage medium or storage device, video data received from a server on the Internet, etc.). it can.

  Further, the video content reproduction program 13B has a message display control function for controlling display of a message presented to the user while the video content data is being viewed. This message is, for example, a message for notifying an error or status requested to be displayed by various application programs such as the OS 13A and the video content reproduction program 13B, a telop, a closed caption, and a control panel for operation.

  The CPU 11 also executes a basic input / output system (BIOS) stored in the BIOS-ROM 19. The BIOS is a program for hardware control.

  The north bridge 12 is a bridge device that connects the local bus of the CPU 11 and the south bridge 16. The north bridge 12 also includes a memory controller that controls access to the main memory 13. The north bridge 12 also has a function of executing communication with the display controller 14.

  The display controller 14 is a device that controls the LCD 15 used as a display of the computer 1. A display signal generated by the display controller 14 is sent to the LCD 15. The LCD 15 displays an image based on the display signal.

  The south bridge 16 controls each device on a peripheral component interconnect (PCI) bus and a low pin count (LPC) bus. The south bridge 16 incorporates an IDE (Integrated Drive Electronics) controller for controlling the HDD 21 and ODD 22 and a memory controller for controlling access to the BIOS-ROM 19. Furthermore, the south bridge 16 also has a function of executing communication with the sound controller 17 and the LAN controller 20.

  Further, the south bridge 16 controls the plurality of regions in the lens unit 15B to be set to either one of the three-dimensional display mode and the two-dimensional display mode in response to a request from the video content reproduction program 13B. Can be output to the lens unit 15B. The lens unit 15B changes the refractive index of the portion in the liquid crystal layer corresponding to each of the plurality of regions, for example, according to the control signal output by the south bridge 16, thereby changing the region to the three-dimensional display mode. Set to one of the dimension display modes. Thus, a window for displaying 3D video by the video content playback program 13B and a window (not limited to one) for displaying 2D video by another application program can be set on the screen of the LCD 15A. A countermeasure when the windows overlap will be described later.

  The sound controller 17 is a sound source device and outputs audio data to be reproduced to the speakers 18A and 18B. The LAN controller 20 is, for example, a wired communication device that executes wired communication of the Ethernet (registered trademark) standard, and the wireless LAN controller 23 is a wireless communication device that executes, for example, wireless communication of the IEEE 802.11 standard. The USB controller 24 executes communication with an external device via, for example, a USB 2.0 standard cable.

  The EC / KBC 25 is a one-chip microcomputer in which an embedded controller for performing power management, a keyboard (KB) 26, and a keyboard controller for controlling a pointing device 27 are integrated. The EC / KBC 25 has a function of powering on / off the computer 1 in accordance with a user operation.

  The TV tuner 30 is a receiving device that receives broadcast program data broadcast by a television (TV) broadcast signal, and is connected to the antenna terminal 30A. The TV tuner 30 is realized as a digital TV tuner capable of receiving digital broadcast program data such as terrestrial digital TV broadcast. The TV tuner 30 also has a function of capturing video data input from an external device.

  FIG. 3 is a block diagram illustrating an example of a functional configuration of the video content reproduction program 13B. The video content playback program 13B has a video playback function for playing back the video content data 31 as 3D video or 2D video. The video content playback program 13B also has a message display control function for displaying various messages displayed during the video playback period so that the user can easily see them.

  When the video content reproduction program 13B is executed by the CPU 11, a video read module 32, a video processing module 34, a video display module 36, and a 2D / 3D mode switching module 38 are realized. The video read module 32, the video processing module 34, the video display module 36, and the 2D / 3D switching module 38 realize a video playback function.

  The video read module 32 reads the video content data 31 from, for example, a storage medium such as a DVD or a storage device such as the HDD 21. Note that the video read module 32 may receive the video content data 31 via the TV tuner 30, the LAN controller 20, the wireless LAN controller 23, and the like. The video content data 31 includes 2D video data for displaying 2D video and / or 3D video data for displaying 3D video. These video data are, for example, compressed and encoded video data (for example, MPEG encoded data). In that case, the video data is decoded and used. The video content data 31 may include various types of metadata. The video read module 32 outputs the read (received) video content data 31 to the video processing module 34.

  The video processing module 34 generates video data using the video content data 31 output by the video read module 32. Specifically, the video processing module 34 first determines whether the video is displayed in the 2D display mode or the 3D display mode. For example, when the video content data 31 includes 3D video data including a right eye video and a left eye video, the video processing module 34 determines to display the video in the 3D display mode. When playing back video content data read from a storage medium, 3D display and 2D display are specified on the storage medium, and the read signal may include specification information. In such a case, the display mode is determined according to this designation information. The video processing module 34 can also determine to display the video in the display mode specified by the user. The user can also select the display mode using, for example, an operation screen including a button for selecting either the 2D display mode or the 3D display mode. Furthermore, the user can determine an area (window) for displaying video data. Note that the display area may be initially determined by default without being determined by the user. The size and position of the display area can be arbitrarily changed from the initial values.

  When the video processing module 34 is determined to display video in the 3D display mode and the video content data 31 includes 3D video data, the video processing module 34 processes the 3D video data to be suitable for 3D display. . For example, when the video content data read from the storage medium for 3D content includes a stream of video data for the left eye and a stream of video data for the right eye, the video processing module 34 performs video data for the left eye of each frame. The pixels of the right-eye video data are rearranged to create one frame of 3D video (also referred to as parallax video) data. In some cases, the storage medium for 3D content stores 1-frame 3D video (parallax video) data in which left-eye video data and right-eye video data are arranged side by side and outputs this as a stream. is there. In this case, the video processing module 34 uses the data read from the storage medium as it is.

  The video processing module 34 requests the 2D / 3D switching module 38 to set the video display area in the 3D display 15 to the 3D display mode. More specifically, the video processing module 34 displays information (such as coordinates) indicating the video display area and information indicating that the specified area (that is, the video display area) is set to the 3D display mode. Output to the 3D switching module 38. The video display area is a window area for displaying video based on the video content data 31, for example. Then, the video processing module 34 outputs the generated 3D video data to the video display module 36.

  When the video processing module 34 is determined to display a video in the 3D display mode and the video content data 31 does not include 3D video data but includes 2D video data, the 2D video data Is subjected to 2D-3D conversion. By the 2D-3D conversion, a plurality of depth values corresponding to a plurality of pixels included in each image frame in the 2D video are estimated, and the estimated depths are considered in consideration of binocular parallax, viewing distance, and the like. A plurality of parallaxes corresponding to the value are calculated. That is, a plurality of parallaxes corresponding to a plurality of pixels included in the image frame are calculated. The video processing module 34 generates left-eye video data and right-eye video data based on the calculated parallax, and rearranges the pixels of the left-eye video data and right-eye video data of each frame. One frame of 3D video (parallax video) data is created. The video processing module 34 requests the 2D / 3D switching module 38 to set the video display area in the 3D display 15 to the 3D display mode. Then, the video processing module 34 outputs the generated 3D video data to the video display module 36.

  Further, when it is determined that the video processing module 34 displays the video in the 2D display mode and the 2D video data is included in the video content data 31, the 2D / 3D switching module 38 stores the content in the 3D display 15. Requests that the video display area be set to the two-dimensional display mode. Then, the video processing module 34 outputs the 2D video data to the video display module 36.

  The 2D / 3D switching module 38 switches the display mode of the video display area in response to a request from the video processing module 34. Specifically, the 2D / 3D switching module 38 sets the designated area to the designated display mode based on the information output by the video processing module 34. For example, when the video processing module 34 requires the video display area to be set to the 3D display mode and the video display area is set to the 2D display mode, the 2D / 3D switching module 38 Is switched from the 2D display mode to the 3D display mode. In addition, when the video processing module 34 is required to set the 2D display mode and the video display area is set to the 3D display mode, the 2D / 3D switching module 38 displays the video display area in the 3D display mode. Switch from mode to 2D display mode.

  In the 3D display mode, the portion corresponding to the image display area in the lens unit 15B is controlled to have a lens function (refractive index) necessary for 3D display. In the 2D display mode, the portion corresponding to the image display area in the lens unit 15B has a lens function necessary for 2D display (that is, the 2D image is displayed as it is without being polarized). Controlled).

  The video display module 36 displays a video in a video display area in the LCD 15A. Specifically, when 3D video (parallax video) data including left-eye video data and right-eye video data is output by the video processing module 34, the video display module 36 displays the 3D video data. Is used to display a three-dimensional video composed of a left-eye video and a right-eye video in a video display area in the LCD 15A. When the 2D video data is output by the video processing module 34, the video display module 36 displays the 2D video on the video display area in the LCD 15A using the 2D video data.

  With the above-described configuration for the video playback function, the user can view the 3D video or the 2D video displayed on the 3D display 15 (video display area). Note that when a 3D image is displayed on the 3D display 15, the left-eye video and the right-eye video displayed in the video display area in the LCD 15A depend on the part corresponding to the video display area in the lens unit 15B. The emission direction of each pixel is controlled. Thus, the user can perceive the image stereoscopically with the naked eye.

  Next, the processing of the video content reproduction program 13B when another window overlaps the 3D video display window will be described with reference to the flowchart of FIG.

  Through the processing described above, the reproduction program 13B displays the 3D video in the 3D display mode in block 402. That is, the video display module 36 supplies 3D video data to a designated area (first window) in the LCD 15A, and the 2D / 3D switching module 38 corresponds to the lens unit 15B and the first window of the lens unit 15B. An electrode drive signal is supplied to control the portion so as to have a lens function (refractive index) necessary for three-dimensional display. That is, the refractive index is controlled so that light from each pixel is emitted in multiple directions.

  When the read video content data is 2D video data as shown in FIG. 5A, the video processing module 34 performs 2D-3D conversion on the 2D video data, and the left eye video data and the right data Eye image data is generated, and 3D image (parallax image) data in which left eye image data and right eye image data are arranged side by side as shown in FIG. 5B is supplied to the first window of the LCD 15A. To do. As a result, a 3D image is displayed in the first window as shown in FIG.

  As shown in FIG. 6 (a), the video processing module 34 reads 3D video data composed of a left-eye video data stream (L) and a right-eye video data stream (R) as shown in FIG. In this case, as shown in FIG. 6B, 3D video (parallax video) data in which left-eye video data and right-eye video data are arranged side by side is supplied to the first window of the LCD 15A. As a result, a 3D image is displayed in the first window as shown in FIG.

  As shown in FIG. 7A, the video processing module 34 is a frame of 3D video (parallax video) in which the left-eye video data and the right-eye video data are arranged side by side as shown in FIG. If it is data (one stream), the data is supplied as it is to the first window of the LCD 15A as shown in FIG. 7B. As a result, a 3D image is displayed in the first window as shown in FIG.

  In any case, as a result of the process in block 402, a 3D image is displayed on the first window W1 on the LCD 15A as shown in FIG.

  The reproduction program 13B determines in block 404 whether another window (second window) is displayed. The second window includes a playback program menu screen and other application program screens.

  When the second window is displayed, the reproduction program 13B determines in block 406 whether or not the second window W2 overlaps at least a part of the first window W1 as shown in FIG. 8B. If the second window W2 overlaps at least part of the first window W1 and the second window W2 is active, the display of the first window W1 is lost, and the left-eye video and the right-eye video are partially displayed. It will be missing. In this case, a stereoscopic image cannot be perceived.

  If the overlap of the two windows is detected at block 406 and the second window W2 is active, the playback program 13B determines at block 408 whether the video content data is 3D-only content. If the video content data is 3D-only content, the 3D video display mode of the first window is stopped at block 410 as shown in FIG. 8C, and a predetermined 2D video is displayed instead. Note that the video content in FIG. 6A includes 3D-only content and 3D content (not 3D-only).

  Some optical disks that store 3D video data permit only 3D display that allows stereoscopic viewing, and prohibit other displays. Such an optical disc also stores designation information “3D only”, and the data stored in such an optical disc is 3D-only content. In block 408, it is determined whether or not “3D only” designation information is included in the video content data read from the optical disc.

  Therefore, since display of 3D-only content is prohibited in the state shown in FIG. 8B, in order to stop the 3D video display of the first window, supply of video content data to the LCD 15A in block 410 To stop. However, in order to reduce the uncomfortable feeling that the first window W1 becomes dark, a predetermined two-dimensional image such as a logo mark of a reproduction program may be displayed. In this case, the 2D / 3D switching module 38 sends an electrode drive signal for controlling the lens unit 15B so that the portion of the lens unit 15B corresponding to the first window W1 has a lens function (refractive index) necessary for two-dimensional display. Supply. The block 410 is not limited to displaying a predetermined two-dimensional image, but a three-dimensional image (parallax image) shown in FIG. 6B may be supplied to the first window of the LCD 15A. In this case, since the lens unit 15B does not have a lens function (refractive index) necessary for three-dimensional display, the image is displayed as an image with a narrow width in the horizontal direction as shown in FIG. Note that the display mode of the active second window may be either the two-dimensional display mode or the three-dimensional display mode.

  Even if the second window W2 overlaps at least part of the first window W1, if the first window W1 is active, the left-eye video and the right-eye video of the first window W1 will not be lost. Block 410 need not be executed.

  After block 410, playback program 13B determines in block 414 whether the overlap of the two windows has been eliminated. Since the sizes and positions of the windows W1 and W2 can be arbitrarily changed, the user may perform an operation so as to eliminate the overlap while viewing the display in FIG. 8C or FIG. 9C. The process waits at block 414 until the overlap is eliminated. When the overlap is eliminated, the process returns to block 402, and the 3D display of the 3D video is resumed in the first window W1. It should be noted that even when the 3D display of the 3D image is stopped in block 410, the interruption position may be stored so that the 3D display of the 3D image can be resumed from the interruption position shown in FIG. good.

  If the video content data is not 3D-only content, at block 412, the video processing module 34 returns the first window W1 to the 2D display mode. Content that is not 3D-only includes 3D video content obtained by performing 2D-3D conversion on 2D video data as shown in FIG. 5, 3D video content (other than 3D only content) shown in FIG. 6, and tertiary shown in FIG. Includes original video content. The 2D / 3D switching module 38 supplies the lens unit 15B with an electrode drive signal for controlling the lens unit corresponding to the first window W1 to have a lens function (refractive index) necessary for two-dimensional display. As described above, the portion of the lens unit corresponding to the first window W1 is controlled so as to have a lens function necessary for two-dimensional display. Therefore, light from each pixel of the LCD 15A is not emitted in multiple directions. Therefore, the data supplied from the video display module 36 to the first window W1 may be 2D video data or 3D video data. That is, the video display module 36 has the two-dimensional video data in FIG. 5A, the three-dimensional video data in FIG. 5B, and one of the left-eye video data and the right-eye video data in FIG. No video data), the parallax video data of FIG. 6B, and the parallax video data of FIGS. 7A and 7B. As a result, the 3D display of the 3D image in the first window W1 is stopped as shown in FIG. 8C, and the 2D display of the 2D image corresponding to the 3D image displayed so far is started. The When the 3D image data of FIGS. 6B, 7A, and 7B is displayed in the first window W1, the lens unit 15B does not have a refraction function, and therefore FIG. As shown in FIG. 5, the image is compressed and displayed in the horizontal direction. When one of the two-dimensional video data in FIG. 5A and the left-eye video data and the right-eye video data in FIG. 6A (video data without parallax) is displayed, the display image is compressed in the horizontal direction. It will never be done.

  After the block 412, the determination in the block 414 is executed, and when the overlap is eliminated, the process returns to the block 402, and the 3D display of the 3D video is resumed in the first window W1.

  As described above, according to the present embodiment, when a 3D image is displayed in a 3D display in a window having a display capable of partially displaying in 3D and 2D, overlapping of other windows is detected. Then, the 3D display of the 3D image of the certain window is stopped. As a result, it is possible to prevent a stereoscopic video of the certain window from being broken by another window and display a meaningless video or a video having a sense of discomfort or discomfort. Instead of stopping the 3D display, displaying the 2D video corresponding to the stopped 3D video in the certain window allows the user to continue viewing the content, but is preferable for the user. When the user changes the position and size of another window and the overlap is eliminated, the original 3D image can be returned to the 3D display, and the convenience of the user is improved.

  Note that all the procedures of the video reproduction process of the present embodiment can be executed by software. For this reason, it is possible to easily realize the same effect as that of the present embodiment simply by installing and executing this program on a normal computer through a computer-readable storage medium storing a program for executing the video reproduction processing procedure. Can do.
