Abstract:
A signal processing circuit includes an auto gain control circuit and amplifies a signal with an amplification ratio determined based on a synchronous signal level having a positive potential with respect to a black level included in a high definition television video signal. In consequence, during the processing of the high definition television video signal, the signal processing is performed with a desired amplification ratio.
