Abstract:
Provided is a head-up display device capable of properly superimposing a virtual image on actual scenery in accordance with the travel condition of a vehicle. The head-up display device comprises: a vehicle information acquisition unit for acquiring vehicle information including a pitching inclination detected by a first orientation sensor and a rolling inclination detected by a second orientation sensor; a control unit for controlling video display on the basis of the vehicle information; a video image display device for forming a video image on the basis of a command from the control unit; a mirror for reflecting the video image formed by the video image display device and projecting the video image onto a windshield or a combiner; and a mirror drive unit for changing the angle and/or the position of the mirror on the basis of a command from the control unit. The control unit adjusts the display state of the virtual image in the video image display area on the basis of the pitching inclination and/or the rolling inclination in the vehicle information, and/or adjusts the angle and/or the position of the mirror via the mirror drive unit.
