ABSTRACT:
A video signal processing circuit, in which a horizontal synchronizing signal is separated from an input analog video signal by a synchronism separating circuit, whether a “H” period of the horizontal synchronizing signal continues for more than a prespecified period of time or not is checked by a synchronizing signal monitoring counter, and power supply to an A/D converter is controlled thereby according to a result the confirmation.
