Video display system, video display method, and video display program

Abstract

An video display system having room in a generation time of a next frame to be generated on the basis of a gaze direction of the user is provided. A video display system includes a wearable device including a reception unit that receive a video, a display unit that displays the video received by the reception unit, an irradiation unit that irradiates eyes of a user with near infrared light, and an imaging unit that images the eyes of the user viewing the video displayed on the display unit, on the basis of the near infrared light, the user wearing the wearable device and viewing the video; a gaze detection unit that detects a gaze point of the user on the basis of a captured image captured by the imaging unit; and a video generation unit that generates a video to be displayed on the wearable device on the basis of the gaze point detected by the gaze detection unit, and the wearable device includes a control unit that instructs an imaging start timing to the imaging unit so that the imaging of the imaging unit can be executed at a timing at which it is estimated that the user is viewing the frame each time each frame of the video to be displayed on the display unit is displayed.

What is claimed is: 
     
         1 . A video display system comprising:
 a wearable device including a reception unit that receives a video,
 a display unit that displays the video received by the reception unit, 
 an irradiation unit that irradiates eyes of a user with near infrared light, and 
 an imaging unit that images the eyes of the user viewing the video displayed on the display unit, on the basis of the near infrared light, the user wearing the wearable device and viewing the video; 
   a gaze detection unit that detects a gaze point of the user on the basis of a captured image captured by the imaging unit; and   a video generation unit that generates a video to be displayed on the wearable device on the basis of the gaze point detected by the gaze detection unit,
 wherein the wearable device includes a control unit that instructs an imaging start timing to the imaging unit so that the imaging of the imaging unit can be executed at a timing at which it is estimated that the user is viewing the frame each time each frame of the video to be displayed on the display unit is displayed.
