In an image processor for synthesizing images that have been taken by multiple
cameras mounted on a vehicle, even if any movable part of the vehicle has changed
its state, the synthesized image will have no unnatural part. A pixel synthesizer
receives the images that have been captured by the cameras included in an imaging
section and generates the synthesized image by reference to a mapping table. Receiving
a signal indicative of the state of a movable part such as the door or hood of
the vehicle, a display mode changer disables at least one of the cameras that is
taking an image to be affected by any change in the state of the movable part.
For that purpose, the changer rewrites mapping data stored on the mapping table
and thereby eliminates the image in question from the synthesized image.
