[0024] figure 1 It is an external view of the video processing device 2 having the viewing zone adjustment device 1 according to the first embodiment, figure 2 It is a block diagram showing its schematic configuration. As shown in these figures, the video processing device 2 includes a stereoscopic video display device 3, a display control unit 4, an imaging device 5, a light receiving unit 6, a tuning decoder 7, and a parallax image conversion unit 8.
[0025] The stereoscopic video display device 3 includes a display panel 31 having pixels arranged in a matrix, and a light control unit 32 arranged opposite to the display panel 31 and having a plurality of exit pupils that control light from each pixel. For the display panel 31, for example, a display panel 31, a plasma display, an EL (Electro Luminescent) panel, etc. can be used. The light control unit 32 is also generally called a parallax barrier. Each exit pupil of the light control unit 32 controls the light. Even at the s...

[0069] According to the second embodiment, when determining the viewing area adjustment policy, not only the number of viewers but also the type of input video is considered.
[0070] Figure 7 It is a block diagram showing the schematic configuration of a video processing device 2 having the viewing zone adjustment device 1 of the second embodiment. Figure 7 The sight adjustment device 1 except figure 2 In addition to the viewing zone adjustment device 1, it also has a video type detection unit 15.
[0071] Figure 7 The video type detection section 15 detects the video type of the input video data. For example, the video type detection unit 15 detects whether the input video data includes video data (stereoscopic three-dimensional data) including depth information or parallax information, or normal two-dimensional video data without depth information or parallax information.
[0072] The reason for using the video type detection unit 15 to detect the video type is that if the inp...

[0086] According to the third embodiment, in addition to the second embodiment, the viewing area adjustment policy is also determined in consideration of the user's preference.
[0087] Picture 10 It is a schematic block diagram of the video processing device 2 having the viewing zone adjustment device 1 of the third embodiment. in Picture 10 In the sight adjustment device 1, except Figure 7 In addition to the configuration of the viewing zone adjustment device 1, it also has a user preference setting unit 16.
[0088] Picture 10 The user preference setting unit 16 sets the viewing zone adjustment policy desired by the user. The user selects a desired viewing area adjustment policy from a plurality of viewing area adjustment policies using a remote control or the like. The user preference setting unit 16 adopts the viewing area adjustment policy selected by the user as necessary based on the viewing area adjustment policy decision table described later.
