Abstract

PURPOSE: To enable a simple circuit to compensate the omission of information, by respectively comparing a picture signal with the 2nd higher reference voltage and the 3rd lower reference voltage than the 1st reference voltage and by extracting white information and black information of high density from the comparison output signals.
