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 15):
A video generating method implemented in a video system comprising\n a display used for presenting an image to a user, and a video generating device for generating the video to be presented by the display, wherein the video generating method comprises\n a video presentation step of presenting the video to the user, performed by the display, \n an imaging step of capturing an image of an eye of a user, performed by the display, \n a transmission step of sending to the video generating device the image captured in the imaging step, performed by the display, \n a reception step of receiving from the video generating device the video for presentation in the video presentation step, performed by the display, \n a reception step of receiving from the display the image captured in the imaging step, performed by the video generating device, \n a transmission step of sending the video to the display, performed by the video generating device, \n a gaze point acquisition step of acquiring the user's gaze point in the video, based on the image captured in the imaging step, performed by the video generating device, \n a gaze point motion acquisition step of acquiring the motion of the user's gaze point, based on the gaze point acquired in the gaze point acquisition step, performed by the video generating device, and \n a calculation step of generating the video, performed by the video generating device, wherein\n based on the gaze point acquired in the gaze point acquisition step, \n using the gaze point as a reference, 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 in the gaze point motion acquisition step, 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.
