Video display system, video display device, and video display method

A video display device wearable by a user and connected with a video image processing device that retains a plurality of video data captured by a plurality of cameras, the video display device comprising:

• a sensor that detects a direction of a sight line of the user;
• a video receiver that receives a wide range video data of the entire celestial sphere generated by the video image processing device and having a 360-degree range around an area where the plurality of cameras is installed;
• a video extractor that segments a predetermined area of video data including a detection result of the sensor from the wide range video data of the entire celestial sphere;
• a luminosity adjuster that adjusts a luminosity of the predetermined area of video data extracted by the video extractor to fall in a certain range of luminosity corresponding to a luminosity of the wide range video data of the entire celestial sphere, and
• a video display that displays the predetermined area of video data adjusted by the luminosity adjuster.
