  • Patent number: 10866415
    Abstract: A head-up display apparatus displays a virtual image suitably overlapped with actual scenery in accordance with a running condition of a vehicle. The head-up display apparatus acquires various kinds of vehicle information which can be detected by a vehicle and the display of the video image is based on the vehicle information. A mirror is configured to reflect the video image formed by the video image display to project onto the windshield. A mirror driver is configured to change an angle of the mirror and a display distance adjusting mechanism is configured to adjust a display distance of the virtual image with respect to the driver. The angle of the mirror is adjusted via the mirror driver based on the vehicle information such that the virtual image can be displayed with respect to the driver to be overlapped with the scenery.
