ABSTRACT:
A color imaging apparatus which produces a luminance signal and a plurality of chrominance signals in order to generate a composite color video signal which is capable of compensating a color reproduction characteristic in response to a variation of the color temperature of the incident light. A signal representative of the color temperature of the light is used to control the gain of the color difference signals and/or control the phase difference between a plurality of color subcarriers on which the chrominance signals are modulated. The color temperature signal can be produced from a white-balancing circuit or by a separate color temperature detector.
