Video display apparatus, video display system, and video display method

A video display system comprising a server that performs image correction processing for a video input signal and a video display apparatus that receives a video signal, having been subjected to the image correction processing, from the server and that displays a video based on the video signal,

• wherein the video display apparatus includes:
• a viewer detection unit that detects a positional relation between a display screen on which the video is displayed and a viewer who watches the video, and that generates viewer position information including a result of the detection;
• an apparatus-side communication processing unit that transmits the viewer position information to the server;
• a video decompression unit that decompresses a compressed image;
• and
• a video display unit that displays the video on the display screen,
• the server includes:
• a server-side communication processing unit that receives the viewer position information;
• an image processing unit that sets, based on the viewer position information, a correction region for an image based on the video input signal, and that executes the image correction processing for the correction region;
• and
• a compression processing unit that performs compression processing for the image having been subjected to the image correction processing while relatively decreasing a compression ratio of the correction region and relatively increasing a compression ratio of an out-of-correction region of the image, which is a region different from the correction region,
• the server-side communication processing unit transmits the image having been subjected to the compression processing to the video display apparatus,
• the apparatus-side communication processing unit receives the image having been subjected to the compression processing, and
• the video decompression unit performs decompression processing for the received image having been subjected to the compression processing.

A video display method that receives an input of a video input signal and that displays a video based on the video input signal, comprising the steps of:

• detecting a positional relation between a display screen on which the video is displayed and a viewer who watches the video;
• setting, based on the positional relation, a correction region of an image based on the video input signal;
• executing image correction processing for the correction region;
• and
• displaying, on the display screen, the video based on the video input signal associated with the image having been subjected to the image correction processing.
