MONITOR AND VEHICLE PERIPHERY MONITOR

A parameter selection section ( 109 ) selects one from a plurality of image synthesis parameters stored in a parameter storage section ( 100 ) according to an output of a vehicle state detection section ( 108 ). An image synthesis section ( 104 ) reads out camera images from frame memories ( 103 ) according to the selected image synthesis parameter and generates a synthesized mage showing a state of vehicle surroundings. A moving object detection section ( 105 ) detects, in the thus generated synthetic image, a moving object region estimated as a region where a moving object is present.
