An image comparison section provided in a monitoring system compares current image data with past image data acquired in at least one preceding cycle when a vehicle is determined to be in motion on the basis of an output signal input from a motion sensing section. On the basis of a comparison result, the image comparison section determines whether or not a camera or an image processing section broke down. When there is a failure, the image comparison section outputs an output signal reporting the failure to the image processing section. Upon receipt of the output signal, the image processing section performs image processing intended for the event of a failure, and transmits failure information while superimposing the failure information on an image signal, thereby changing a display device to a monochrome display or an alarm display.
