Abstract
The present invention enables recognition of traffic light lamp color in place of or in addition to simply displaying the traffic light lamp color in a color image. A projection unit projects, towards a part subject to projection, display light L that can display an image at a variable display distance. A lamp color information acquisition unit acquires a lamp color of a traffic light which a vehicle will be driving through. A display distance adjustment unit changes the display distance of the image based on the lamp color acquired by an information acquisition unit.
