Abstract

A HUD including a projection display unit, a housing, a cover, a region detection unit, an object removing mechanism and an object removal control unit is provided. The projection display unit spatially modulates light emitted from a light source as image information and projects image light obtained from spatial modulation onto a windshield to display an image. The housing accommodates the projection display unit and has an opening portion through which the image light exits. The cover covers the opening portion. The region detecting unit detects an object adhesion region in which the object is adhered to the cover. The object removing mechanism removes an object adhered to a front surface of the cover by scraping the front surface of the cover. The object removal control unit activates the object removing mechanism when important display content is included in a portion of the image light, the portion being blocked.
