ABSTRACT:
A video signal processing circuit of a single chip color camera including a color separation filter for performing a color separation on incident light passing therethrough so as to output color separated light, a solid state pickup device for picking up the color separated light passed through the color separation filter and outputting a video signal, main circuit means for generating a first luminance signal, a second luminance signal, a first color difference signal, and a second color difference signal from the video signal, compensating signal generating means for obtaining a compensation signal from the first and second color difference signals, operational means for applying the compensation signal to the first luminance signal to produce as output luminance signal, and color temperature detection means for detecting a color temperature of the incident light and outputting a DC control voltage so as to determine the compensation signal.
