Abstract
A head-mounted display device includes: an image-light generating unit for right eye that generates image light from image data for right eye and emits the image light; an image-light generating unit for left eye that generates image light from image data for left eye and the image light; a light guide units that guide the emitted image lights to the left and right eyes of the user; and a display control unit that transmits control signals for controlling the emission of the image lights respectively to the image-light generating unit for right eye and the image-light generating unit for left eye. The display control unit transitions, according to a condition set in advance, the head-mounted display device to a power saving state for causing one of the image-light generating unit for right eye and the image-light generating unit for left eye to stop the emission of the image light.
