Abstract: There are provided right and left side-rearward cameras, an inside camera to detect a driver's eyeball position, main HUDs comprising projectors to form virtual images by projecting image information picked up by the cameras to reflecting mirrors and drive portions to adjust positions of the virtual images, and a ECU to control the projectors and the drive portions. The controller is configured to perform the process of calculating a distance between the eyeball position and a normal virtual-image display position which is located at a front end and an end portion, in a vehicle width direction, of a bonnet, and controlling the main HUDs such that a normal main view v1 is displayed at the normal virtual-image display position.
