Abstract
A synthetic image viewed from a virtual point of view above a vehicle is generated, using images captured by a plurality of cameras shooting surroundings of the vehicle. In the synthetic image, an illustration image or an actual image of the vehicle is displayed in a vehicle region in which the vehicle is present. The area around the vehicle that is not shot by any of the cameras is displayed as a blind spot region.
