Abstract
A video signal processing apparatus comprises an A/D converter for digitizing an analog video signal, an integration circuit for integrating the digitized video signal within a predetermined integration range, a picture display device for displaying a picture based on an integration output, and a control unit which, when an offset adjustment signal is inputted to the A/D converter, corrects the offset value so as to eliminate a difference between the integration value of the integration circuit and a preliminarily set specified value, and determines whether or not offset adjustment is completed based on the number of times when the corrected offset value is within a range defined by adding a predetermined error to the specified value.
