Abstract
It is an object to identify a failed portion in a circuit for image processing and notify a service center of the failed portion, thereby enabling the failed circuit to be promptly replaced. Circuit portions of image processing units are constructed on separate substrates. As processing routes of an image signal which is inputted from an A/D converting unit, a route in which the image signal passes through a given circuit portion and a route in which the image signal doesn't pass therethrough are set. Data of a predetermined pattern is processed by those processing routes. The presence or absence of a failure of each circuit portion is discriminated from the processing results. The discrimination result is transmitted to an external apparatus installed in a service center.
