Problems solved by technology
However, it is difficult to automatically adjust the viewing area because viewers are not always in the same location and the number of viewers is not always fixed
In fact, in many cases the stereoscopic effect cannot be obtained by automatically adjusting the viewing area
In such cases, the viewer has to move unnecessarily to find the right position and in the end it may be difficult to enjoy stereoscopic video easily
[0006] In addition, naked-eye conventional 3D televisions have no effective means of telling individual viewers whether they are in a position where a stereoscopic effect can be obtained
Therefore, individual viewers move excessively to find a better position and feel that it is difficult to enjoy stereoscopic video easily

Embodiment Construction
[0019] Embodiments will now be explained with reference to the drawings.
[0020] figure 1 is an external view of the video display device 100 according to an embodiment, and figure 2 It is a block diagram showing its schematic structure. The video display device 100 has a liquid crystal panel 1 , a lenticular lens 2 , a camera (camera, camera) 3 , a light receiver 4 and a video processing device 5 .
[0021] The liquid crystal panel 1 can display parallax images, so that the viewer can watch stereoscopic video. For example, the liquid crystal panel 1 is a 55-inch panel having 11520 (=1280*9) pixels in the horizontal direction and 720 pixels in the vertical direction. In addition, each pixel is composed of three sub-pixels, that is, R sub-pixels, G sub-pixels, and B sub-pixels arranged in the vertical direction. The liquid crystal panel 1 is irradiated with light from a backlight device (not shown) arranged behind. Light having a brightness corresponding to a parallax im...

A video processing device has a viewer detector to recognize a face of a viewer using a video shot by a camera in order to acquire position information of the viewer, a subscreen display controller to superimpose a live video shot by the camera on a part of a display screen of a display device as a subscreen, a viewing area frame display controller to display, in the live video in the subscreen, a viewing area frame representing a viewing position where the viewer is viewable a stereoscopic video, and a face frame display controller to display a first face frame showing that the stereoscopic video is viewable when the viewer is located within the frame, and to display a second face frame showing that the stereoscopic video is not viewable when the viewer is located outside the frame.
Description
[0001] References to related applications [0002] This application is based upon and claims the benefit of priority from prior Japanese Patent Application No. 2011-242674 filed on November 4, 2011, the entire contents of which are incorporated herein by reference. technical field [0003] Embodiments of the present invention relate to a video processing device and a video processing method capable of adjusting a viewing area where a stereoscopic video can be viewed. Background technique [0004] A TV set capable of displaying stereoscopic video that can be watched by the naked eye has attracted people's attention. However, with such televisions, the stereoscopic effect may not be obtained depending on the viewing position, and a viewer who wishes to obtain a sufficient stereoscopic effect needs to move to a position where the stereoscopic effect can be obtained. Specifically, when there are a plurality of viewers, it is very troublesome for each viewer to move to a positio...
