Description

  Embodiments described herein relate generally to a video processing apparatus and a video processing method.

  In recent years, stereoscopic image display devices (so-called naked-eye 3D televisions) that allow viewers to view stereoscopic images with the naked eye without using special glasses have become widespread. This stereoscopic video display device displays a plurality of images with different viewpoints. If the viewer's position is appropriate, the viewer sees different parallax images for the left eye and the right eye, and thus can recognize the image in three dimensions.

  Among stereoscopic video content (3D content), for example, normal 3D content such as frame packing (FP), side-by-side (SBS), and top-and-bottom (TAB) includes two parallax images for left eye and right eye. It is. When viewing 2D video content as a stereoscopic video, a plurality of parallax images (for example, three or more parallaxes) are generated by 2D3D conversion, and the two-dimensional video is three-dimensionalized and then displayed on the liquid crystal panel.

  A stereoscopic video composed of two parallax images for the left eye and right eye can feel a great sense of depth and depth, but has a narrow range (viewing zone) where it can be seen stereoscopically. On the other hand, a stereoscopic video composed of three or more parallax images has a wide viewing area but is inferior in stereoscopic effect. Thus, there is a trade-off relationship between the stereoscopic effect of the stereoscopic image and the wide viewing area.

  Embodiments according to the present invention will be specifically described below with reference to the drawings.

  FIG. 1 is an external view of a video processing apparatus 100 according to an embodiment, and FIG. 2 is a block diagram showing a schematic configuration thereof. The video processing apparatus 100 includes a liquid crystal panel 1, a lenticular lens 2, a camera 3, a light receiving unit 4, and a controller 10.

  The liquid crystal panel (display unit) 1 displays a plurality of parallax images that can be observed as stereoscopic images by a viewer in the viewing area. The liquid crystal panel 1 is, for example, a 55-inch panel, and 11520 (= 1280 * 9) pixels in the horizontal direction and 720 pixels in the vertical direction are arranged. In each pixel, three subpixels, that is, an R subpixel, a G subpixel, and a B subpixel are formed in the vertical direction. The liquid crystal panel 1 is irradiated with light from a backlight device (not shown) provided on the back surface. Each pixel transmits light having a luminance corresponding to a parallax image signal (described later) supplied from the controller 10.

  The lenticular lens (aperture control unit) 2 outputs a plurality of parallax images displayed on the liquid crystal panel 1 (display unit) in a predetermined direction. The lenticular lens 2 has a plurality of convex portions arranged along the horizontal direction of the liquid crystal panel 1, and the number thereof is 1/9 of the number of pixels in the horizontal direction of the liquid crystal panel 1. The lenticular lens 2 is affixed to the surface of the liquid crystal panel 1 so that one convex portion corresponds to nine pixels arranged in the horizontal direction. The light transmitted through each pixel is output in a specific direction with directivity from the vicinity of the top of the convex portion.

  The liquid crystal panel 1 of the present embodiment can display a stereoscopic image by a multi-parallax method (integral imaging method) of 3 or more parallax or a 2-parallax method, and can also display a normal two-dimensional image. .

  In the following description, an example in which nine pixels are provided corresponding to each convex portion of the liquid crystal panel 1 and a 9-parallax multi-parallax method can be adopted will be described. In the multi-parallax method, the first to ninth parallax images are displayed on nine pixels corresponding to the respective convex portions. The first to ninth parallax images are images obtained by viewing the subject from nine viewpoints arranged along the horizontal direction of the liquid crystal panel 1. The viewer can stereoscopically view the video through the lenticular lens 2 by viewing one parallax image of the first to ninth parallax images with the left eye and the other parallax image with the right eye. According to the multi-parallax method, the viewing zone can be expanded as the number of parallaxes is increased. The viewing area refers to an area in which an image can be viewed stereoscopically when the liquid crystal panel 1 is viewed from the front of the liquid crystal panel 1.

  On the other hand, in the 2-parallax method, the right-eye parallax image is displayed on four of the nine pixels corresponding to each convex portion, and the left-eye parallax image is displayed on the other five. The left-eye and right-eye parallax images are images in which the subject is viewed from the left viewpoint and the right viewpoint among the two viewpoints arranged in the horizontal direction. The viewer can stereoscopically view the video through the lenticular lens 2 by viewing the left-eye parallax image with the left eye and the right-eye parallax image with the right eye. According to the two-parallax method, the stereoscopic effect of the displayed image is more easily obtained than in the multi-parallax method, but the viewing area is narrower than that in the multi-parallax method.

  The liquid crystal panel 1 can also display a two-dimensional image by displaying the same image on nine pixels corresponding to each convex portion.

  In the present embodiment, the relative positional relationship between the convex portion of the lenticular lens 2 and the displayed parallax image, that is, how to display the parallax image on the nine pixels corresponding to each convex portion, The viewing zone can be variably controlled according to the situation. Hereinafter, control of the viewing zone will be described by taking a multi-parallax method as an example.

FIG. 3 is a view of a part of the liquid crystal panel 1 and the lenticular lens 2 as viewed from above. The shaded area in the figure shows the viewing area, and the image can be viewed stereoscopically when the liquid crystal panel 1 is viewed from the viewing area. The other areas are areas where reverse viewing and crosstalk occur, and it is difficult to stereoscopically view the video.
3 shows the relative positional relationship between the liquid crystal panel 1 and the lenticular lens 2, more specifically, the distance between the liquid crystal panel 1 and the lenticular lens 2, or the horizontal shift between the liquid crystal panel 1 and the lenticular lens 2. FIG. It shows how the viewing zone changes depending on the amount.

  Actually, since the lenticular lens 2 is attached to the liquid crystal panel 1 with high accuracy, it is difficult to physically change the relative position between the liquid crystal panel 1 and the lenticular lens 2. .

  Therefore, in the present embodiment, the relative positional relationship between the liquid crystal panel 1 and the lenticular lens 2 is apparently displayed by shifting the display positions of the first to ninth parallax images displayed on each pixel of the liquid crystal panel 1. Change and thus adjust the viewing zone.

  For example, when the first to ninth parallax images are respectively displayed on nine pixels corresponding to the respective convex portions (FIG. 3A), the parallax images are displayed while being shifted to the right as a whole (FIG. 3). (B)), the viewing zone moves to the left. Conversely, when the parallax image is displayed shifted to the left as a whole, the viewing zone moves to the right.

  Further, when the parallax image is not shifted in the vicinity of the center in the horizontal direction, and the parallax image is displayed with a larger shift toward the outside toward the outer side of the liquid crystal panel 1 (FIG. 3C), the viewing zone is closer to the liquid crystal panel 1. Moving. In addition, what is necessary is just to interpolate suitably the pixel between the parallax image which shifts and the parallax image which does not shift, and the pixel between the parallax images from which the shift amount differs according to a surrounding pixel. Contrary to FIG. 3C, when the parallax image is not shifted near the center in the horizontal direction, and the parallax image is displayed with a large shift toward the center toward the outside of the liquid crystal panel 1, the viewing area is the liquid crystal panel 1. Move away from the camera.

  As described above, the viewing area can be moved in the left-right direction or the front-rear direction with respect to the liquid crystal panel 1 by shifting the whole or part of the parallax image. In FIG. 3, only one viewing area is shown for the sake of simplification, but actually, as shown in FIG. 4, a plurality of viewing areas 21 exist in the viewing area P, and these are linked together. Moving. The viewing zone is controlled by the controller 10 shown in FIG. Note that the viewing area other than the viewing area 21 is the reverse viewing area 22 in which it is difficult to view a good stereoscopic image due to occurrence of reverse viewing or crosstalk.

  Returning to FIG. 1, each component of the video processing apparatus 100 will be described.

  The camera 3 is attached at a predetermined elevation angle near the lower center of the liquid crystal panel 1 and photographs a predetermined range in front of the liquid crystal panel 1. The captured video is supplied to the controller 10 and used to detect information about the viewer such as the viewer's position and the viewer's face. The camera 3 may shoot either a moving image or a still image.

  The light receiving unit 4 is provided, for example, on the left side of the lower part of the liquid crystal panel 1. And the light-receiving part 4 receives the infrared signal transmitted from the remote control which a viewer uses. Whether the infrared signal is to display a stereoscopic image or a two-dimensional image, whether to use a multi-parallax method or a two-parallax method when displaying a stereoscopic image, whether to control the viewing area, Including signals indicating the like.

  Next, details of the components of the controller 10 will be described. As shown in FIG. 2, the controller 10 includes a tuner decoder 11, a parallax image conversion unit 12, a viewer detection unit 13, a viewing area information calculation unit 14, an image adjustment unit 15, and a display method selection unit 16. And a storage unit 17. The controller 10 is mounted as one IC (Integrated Circuit), for example, and is disposed on the back side of the liquid crystal panel 1. Of course, a part of the controller 10 may be implemented by software.

  A tuner decoder (reception unit) 11 receives and selects an input broadcast wave and decodes an encoded video signal. When a data broadcast signal such as an electronic program guide (EPG) is superimposed on the broadcast wave, the tuner decoder 11 extracts it. Alternatively, the tuner decoder 11 receives an encoded video signal from a video output device such as an optical disk playback device or a personal computer instead of a broadcast wave, and decodes it. The decoded signal is also called a baseband video signal, and is supplied to the parallax image conversion unit 12. When the video processing apparatus 100 does not receive a broadcast wave and displays a video signal received exclusively from a video output device, a decoder having a decoding function may be provided as a receiving unit instead of the tuner decoder 11.

  The video signal received by the tuner decoder 11 may be a two-dimensional video signal, or may be a three-dimensional video signal including left-eye and right-eye images (that is, two parallax images). Examples of the latter include video signals by frame packing (FP), side-by-side (SBS), top-and-bottom (TAB) method, and the like. The video signal may be a three-dimensional video signal including three or more parallax images.

  The tuner decoder 11 reads a flag indicating the content type included in the baseband video signal. Thereby, it is possible to determine the content type of the input video signal.

  The parallax image conversion unit 12 converts the baseband video signal into a desired video signal in accordance with the video display method selected by the display method selection unit 16 described later. The parallax image conversion unit 12 converts the baseband video signal into a plurality of parallax image signals and supplies them to the image adjustment unit 15 in order to stereoscopically display the video. When the selected video display method is a 2D video display method (2D method), the parallax image conversion unit 12 supplies the video signal of the 2D video content to the image adjustment unit 15 as it is.

  The parallax image conversion unit 12 has different processing contents depending on which of the multi-parallax method and the two-parallax method is adopted. The processing content of the parallax image conversion unit 12 differs depending on whether the baseband video signal is a two-dimensional video signal or a three-dimensional video signal.

  When the two-parallax method is adopted, the parallax image conversion unit 12 generates left-eye and right-eye parallax image signals corresponding to the left-eye and right-eye parallax images, respectively. More specifically, as follows.

  When a two-parallax method is adopted and a 3D video signal including a left-eye image and a right-eye image is input, the parallax image conversion unit 12 can display the left-eye and right-eye parallax images in a format that can be displayed on the liquid crystal panel 1. Generate a signal. When a 3D video signal including three or more images is input, for example, using any two of them, the parallax image conversion unit 12 generates a left-eye parallax image signal and a right-eye parallax image signal.

  In contrast, when a two-dimensional parallax method is used and a two-dimensional video signal that does not include parallax information is input, the parallax image conversion unit 12 uses the left eye for the left eye based on the depth value of each pixel in the video signal. And a right-eye parallax image signal is generated. The depth value is a value indicating how much each pixel is displayed so as to be seen in front of or behind the liquid crystal panel 1. The depth value may be added to the video signal in advance, or the depth value may be generated by performing motion detection, composition identification, human face detection, and the like based on the characteristics of the video signal. In the parallax image for the left eye, the pixel seen in the foreground needs to be displayed shifted to the right side from the pixel seen in the back. Therefore, the parallax image conversion unit 12 generates a left-eye parallax image signal by performing a process of shifting the pixel that appears in the foreground in the video signal to the right. The larger the depth value, the larger the shift amount.

  On the other hand, when the multi-parallax method is adopted, the parallax image conversion unit 12 generates first to ninth parallax image signals corresponding to the first to ninth parallax images, respectively. More specifically, as follows.

  When the multi-parallax method is adopted and a two-dimensional video signal or a three-dimensional video signal including an image of 8 parallax or less is input, the parallax image conversion unit 12 uses the left-eye and right-eye from the two-dimensional video signal. The first to ninth parallax image signals are generated based on the depth information in the same manner as the generation of the parallax image signal.

  When a multi-parallax method is adopted and a three-dimensional video signal including an image of 9 parallax is input, the parallax image conversion unit 12 generates the first to ninth parallax image signals using the video signal.

  The viewer detection unit 13 detects the viewer using the video shot by the camera 3. More specifically, the viewer detection unit 13 performs face recognition using an image captured by the camera 3 and acquires viewer information (for example, viewer face information and position information). Moreover, since the viewer detection part 13 can track even if a viewer moves, it can also grasp the viewing time for every viewer.

  The viewer detection unit 13 supplies the number of viewers to the display method selection unit 16 and supplies the viewer position information to the viewing area information calculation unit 14.

  The viewer's position information is represented as, for example, positions on the X axis (horizontal direction), Y axis (vertical direction), and Z axis (direction orthogonal to the liquid crystal panel 1) with the center of the liquid crystal panel 1 as the origin. The The position of the viewer 20 shown in FIG. 4 is represented by coordinates (X1, Y1, Z1). More specifically, the viewer detection unit 13 first recognizes the viewer by detecting a face from the video captured by the camera 3. Next, the viewer detection unit 13 calculates the position (X1, Y1) on the X axis and the Y axis from the position of the viewer in the video, and calculates the position (Z1) on the Z axis from the size of the face. When there are a plurality of viewers, the viewer detector 13 may detect a predetermined number, for example, 10 viewers. In this case, when the number of detected faces is larger than 10, for example, the positions of 10 viewers are detected in order from the position closer to the liquid crystal panel 1, that is, the position on the Z-axis is smaller.

  The viewing area information calculation unit 14 calculates a control parameter for setting a viewing area in which the selected viewer is accommodated, using the position information of the viewer selected by the viewer selection unit 16 described later. This control parameter is, for example, an amount by which the parallax image described in FIG. 3 is shifted, and is a single parameter or a combination of a plurality of parameters. Then, the viewing zone information calculation unit 14 supplies the calculated control parameter to the image adjustment unit 15.

  More specifically, in order to set a desired viewing zone, the viewing zone information calculation unit 14 uses a viewing zone database in which control parameters are associated with viewing zones set by the control parameters. This viewing area database is stored in the storage unit 17 in advance. The viewing zone information calculation unit 14 searches the viewing zone database to find a viewing zone in which the selected viewer can be accommodated.

  The image adjusting unit (viewing zone control unit) 15 supplies the liquid crystal panel 1 after adjusting the parallax image signal according to the calculated control parameter in order to control the viewing zone. . The liquid crystal panel 1 displays an image corresponding to the adjusted parallax image signal.

  The display method selection unit 16 selects one of a plurality of video display methods and supplies the selected video display method to the parallax image conversion unit 12. The video display method includes a 2D method for displaying a two-dimensional image, a two-parallax method for displaying a stereoscopic image including two parallax images for right eye and left eye, and a stereoscopic image including three or more parallax images. There is a multi-parallax method for displaying.

  The display method selection unit 16 may refer to the setting of the 3D viewing mode and select a video display method based on the setting content. This 3D viewing mode is set from a setting menu for the user to switch the 3D display method, and is set to a two-parallax method or a multi-parallax method (direct stereo setting auto / off). A button for selecting the two-parallax method and a button for selecting the multi-parallax method may be provided on the remote controller, and the 3D viewing mode may be set by the viewer pressing one of the buttons.

  The display method selection unit 16 may be supplied with information related to the content type of the input video signal from the tuner decoder 11 and may select a video display method based on the content type.

  The storage unit 17 is a non-volatile memory such as a flash memory, and stores the setting of the 3D viewing mode in addition to the viewing area database. The display method selection unit 16 reads the 3D viewing mode setting from the storage unit 17. The storage unit 17 may be provided outside the controller 10.

  The configuration of the video processing apparatus 100 has been described above. In the present embodiment, an example is shown in which the viewing zone is controlled by using the lenticular lens 2 and shifting the parallax image, but the viewing zone may be controlled by other methods. For example, instead of the lenticular lens 2, a parallax barrier may be provided as the opening control unit 2 '. FIG. 5 is a block diagram showing a schematic configuration of a video processing apparatus 100 ′ that is a modification of the present embodiment shown in FIG. 2. As shown in the figure, the controller 10 ′ of the video processing apparatus 100 ′ includes a viewing zone control unit 15 ′ instead of the image adjustment unit 15. The viewing zone control unit 15 ′ controls the aperture control unit 2 ′ according to the control parameter calculated by the viewing zone information calculation unit 14. In the case of this modification, the control parameters are a distance between the liquid crystal panel 1 and the opening control unit 2 ', a horizontal shift amount between the liquid crystal panel 1 and the opening control unit 2', and the like.

  In the present modification, the viewing zone is controlled by controlling the output direction of the parallax image displayed on the liquid crystal panel 1 with the aperture control unit 2 ′. In this way, the aperture control unit 2 ′ may be controlled by the viewing zone control unit 15 ′ without performing the process of shifting the parallax image.

(First embodiment)
Next, a video processing method by the video processing apparatus 100 (100 ′) configured as described above will be described with reference to the flowchart of FIG.
(1) The tuner decoder 11 decodes the input video signal and generates a baseband video signal (step S11).
(2) The display method selection unit 16 refers to the setting of the 3D viewing mode stored in the storage unit 17 (step S12), and selects the multi-parallax method when the 3D viewing mode is set to the multi-parallax method. (Step S13) When the 3D viewing mode is set to the 2-parallax method, the process proceeds to Step S14.
(3) The tuner decoder 11 reads a flag indicating the content type included in the baseband video signal (step S14). If the content type of the input video signal is determined, if it is 2D video content, the display method selection unit 16 selects the 2D method (step S15), whereas if it is 3D content, the display method selection unit 16 sets 2 A parallax method is selected (step S16).
(4) The parallax image conversion unit 12 processes the baseband video signal based on the display method selected by the display method selection unit 16 (step S17). Specifically, the parallax image conversion unit 12 converts the baseband video signal into two parallax image signals for the left eye and the right eye when the 2 parallax method is selected, and when the 2D method is selected. The baseband video signal of 2D video is output as it is, and when the multi-parallax method is selected, the baseband video signal is converted into three or more parallax image signals.
According to the first embodiment, the 2-parallax method or the multi-parallax method is selected according to the 3D viewing mode, and the 2-parallax method or the 2D method is selected according to the content type. In the case of the multi-parallax method, since the viewing area is wide, many people in front of the video processing apparatus can enjoy stereoscopic video. On the other hand, in the case of the 2-parallax method, the viewer can view the left and right parallax images of the 3D content as they are, and thus can enjoy a stereoscopic image with excellent stereoscopic effect.

(First modification)
Next, the video processing method according to the first modification of the first embodiment will be described with reference to the flowchart of FIG. As described above, 3D content including two parallax images is excellent in stereoscopic effect but has a narrow viewing area. Therefore, when the number of viewers is large, it is difficult for all viewers to view stereoscopic images. Therefore, in this modified example, even when the 3D viewing mode is set to the 2-parallax method, the multi-parallax method is switched according to the number of viewers. Since steps other than step S160 are the same as those in the first embodiment, detailed description thereof is omitted.
(1) The viewer detection unit 13 detects a viewer using the video shot by the camera 3 (step S161).
(2) The display method selection unit 16 determines whether or not there are a plurality of viewers and does not fit in the viewing zone (step S162), and when there are a plurality of viewers and does not fit in the viewing zone, multi-parallax A method is selected (step S163), otherwise a two-parallax method is selected (step S164).
According to the first modification, when there are a plurality of viewers and they do not fall within the viewing area, the multi-parallax method is selected, so that the plurality of viewers can enjoy the stereoscopic video.

(Second modification)
Next, a video processing method according to a second modification of the first embodiment will be described along the flowchart of FIG. In the first embodiment, in the case of 2D video content, a 2D video is displayed as it is, but in this modification, a 2D video is converted to a 3D video (2D3D conversion) to display a 3D video. Since steps other than step S15 ′ and step S17 ′ are the same as those in the first embodiment, detailed description thereof is omitted.
(1) When the content type is 2D video content (2D content), the display method selection unit 16 selects a multi-parallax method (step S15 ′).
(2) The parallax image conversion unit 12 performs 2D3D conversion of the two-dimensional video signal, and converts the baseband video signal of the 2D video content into a stereoscopic video signal including three or more parallax images (step S17 ′). . Note that the baseband video signal of the 2D video content may be converted into a stereoscopic video signal including two parallax images for the right eye and the left eye.
According to the second modified example, even in the case of 2D video content, the viewer can enjoy stereoscopic video by performing 2D3D conversion and displaying in a multi-parallax method.

(Second Embodiment)
In the second embodiment, a display method is selected based on the content type (3D content type) of stereoscopic video. The video processing method according to this embodiment will be described below along the flowchart of FIG.
(1) The tuner decoder 11 decodes the encoded input video signal, generates a baseband video signal, and then reads a flag indicating the 3D content type included in the baseband video signal (step S21).
(2) As a result of determination of the 3D content type (step S22), the display method selection unit 16 selects a multi-parallax method in the case of 2D3D converted content (step S23), and in the case of 3D content other than 2D3D converted content Selects a two-parallax method (step S24). Here, the 2D3D converted content is a stereoscopic video content converted from a two-dimensional video to a stereoscopic video by 2D3D conversion.
Even in the case of 3D content, when there are a plurality of viewers and they do not fall within the viewing zone, the multi-parallax method may be selected. That is, instead of step S24, step S160 of the first modified example described above may be performed.
(3) The parallax image conversion unit 12 processes the baseband video signal based on the display method selected by the display method selection unit 16 (step S25). Specifically, the parallax image conversion unit 12 converts the baseband video signal into two parallax image signals for the left eye and the right eye when the two-parallax method is selected, and when the multi-parallax method is selected. Converts the baseband video signal into three or more parallax image signals.
According to the second embodiment, an appropriate display method is selected from a two-parallax method that prioritizes the stereoscopic effect of a stereoscopic image and a multi-parallax method that prioritizes the viewing area according to the 3D content type.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention.
