Abstract:
Appropriate reduction of transferred data volume is used to deliver interruption-free video to a user, minimizing viewing discomfort. A head-mounted display secured to the head of a user and a video generating device that generates a video for presentation to the user by the head-mounted display are combined in a video system. In the head-mounted display, a presentation unit presents the video to the user, an imaging unit captures an image of the user's eye, the first communication unit sends the captured image to the video generating device, and receives the video from the video generating device. In the video generating device, a second communication unit receives captured images from the head-mounted display and sends a video to the head-mounted-display, a gaze point acquisition unit acquires, based on the captured images, the gaze point of the user in the video, a calculation unit defines a designated region based on the acquired gaze point, and generates the video, wherein the data volume per unit pixel count used for the exterior of the designated region is reduced compared to the data volume used for the interior of the designated region.

Claim (Index 17):
A video generating program, executed by a video generating device, for generating a video to be transmitted to a display that is presenting an image to a user, wherein the program comprises:\n a function to receive an image capture by the display of the user's eye and to transmit the video to the display, a gaze point acquisition function for acquiring the gaze point of the user in the video, based on the image received by the communication unit, a gaze point motion acquisition function for acquiring the user's gaze point motion, based on the gaze point acquired by the gaze point acquisition function, a calculation function for generating the video, wherein\n based on the gaze point acquired by the gaze point acquisition function, using the gaze point as a reference, \n a designated region is set, having a shape defined by a major axis and a minor axis, or a long edge and a short edge, \n the direction of the major axis or the direction of the long edge of the designated area is set according to the direction of the gaze point motion, acquired by the gaze point motion acquisition function, and \n the video is generated with a reduced video data volume per unit pixel count outside of the designated region, compared to the video calculated for the inside of the designated region..
