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.

A gaze detection system includes a head mounted display and a gaze detection device detecting the gaze of the user. The head mounted display illuminate users eyes with infrared light, displays three-dimensional image comprising a plurality of layers in the depth direction and captures an image of user's eye illuminated by the infrared light. The gaze detection device detects the user's right eye's gaze direction (vector) and left eye's gaze direction (vector) with use of the captured images. The gaze detection device identifies the layer that the user is gazing at by selecting the layer having the shortest distance between the intersection points of the right eye gaze vector and the left eye gaze vector with each layer as a gaze point in the depth direction.
