A video signal processing circuit is supplied with an analog composite video signal formed by combining at least a luminance signal with a sync signal, and processes the analog composite video signal. The video signal processing circuit has an analog filter which removes high-frequency components from the analog composite video signal, a sync separation circuit which separates a sync signal from an output signal from the analog filter, an AD converter which performs AD conversion on the analog composite video signal, and a digital video signal processing circuit which performs predetermined video signal processing on the composite video signal digitized by the AD converter, by using the sync signal obtained by the sync separation circuit.
