Abstract
A video signal processing circuit of a CCD-type color video camera includes a gamma-correcting circuit section, a delay circuit section, a chrominance signal processor and a luminance signal processor. Accordingly, the circuit is configured such that gamma-compensation processing is performed before the separation of the luminance and chrominance signals, and a DC fluctuation due to the gamma-compensation processing is compensated in the luminance signal processor. Thus, horizontal noise caused by the gamma correction can be eliminated, which not only improves picture quality but also enables a reduction in chip size.
