Abstract
A camera is disposed on a door mirror whose operating position is changeable between a deployed position and a retracted position, so that the positional relationship of the camera with a vehicle body changes as the operating position of the door mirror changes. A region corresponding to the operating position of the door mirror is partially extracted from the entire shot area of an image taken by the camera. That is, the angular direction of the region partially extracted from the entire shot area taken by the camera when the door mirror is in the deployed position and the angular direction of the region partially extracted from the entire shot area taken by the camera when the door mirror is in the retracted position are made different from each other by an angle equal to the angle difference between the two positions of the door mirror. The camera-taken images of the extracted regions are conformed to the screen of a display. Thus, the vehicle traveling direction appearing on the display remains unchanged regardless of changes in the operating position of the door mirror.
