Abstract
A head-up display (HUD) automatic correction method includes: projecting, by a HUD device, a head-up display image onto a windshield of a vehicle; photographing, by a camera disposed outside of the vehicle, the head-up display image; generating, by an image processing unit, a correction signal by analyzing the head-up display image photographed by the camera; and controlling, by a HUD controller, the HUD device to correct the head-up display image using the correction signal.
