Abstract

A head up display device includes an image generation unit, an imaging unit, an infrared light splitting element, and at least one infrared light detecting element. The infrared light splitting element is located on a transmission path of at least one ambient light beam, and configured to split an infrared light beam from the at least one ambient light beam. The at least one infrared light detecting element is located on a transmission path of the infrared light beam of the at least one ambient light beam, and configured to detect light intensity of the infrared light beam. When the at least one infrared light detecting element detects that the light intensity of the infrared light beam exceeds a predetermined threshold, the head up display device reduces light intensity of a portion of the at least one ambient light beam transmitted to the image generation unit.
