Patent ID: 8803764

Claim:
A head-mount type display device adapted to make a user visually recognize a virtual image, comprising: an image light generation section adapted to generate image light representing an image using image data and then emit the image light; a light guide section adapted to guide the image light, which is emitted, to eyes of the user; a receiving section adapted to receive the image data; and a control section, which is connected to the receiving section, controls image display by the image light generation section, and has a transmitting section adapted to transmit the image data to the receiving section, wherein the control section controls luminance of the image light generation section so as to degrade visibility of the virtual image for a predetermined period of time in a case in which a disturbance in data communication between the transmitting section and the receiving section is presumed, and wherein the control section controls the luminance of the image light generation section so as to degrade the visibility of the virtual image for a predetermined period of time in a case in which a clock rate of the transmitting section is varied in accordance with a variation in a data amount of the image data transmitted between the transmitting section and the receiving section.
