摘要： A color signal processing device for processing a carrier chrominance signal is arranged to produce a first sampling signal by sampling the carrier chrominance signal according to a sampling clock signal synchronized with a reference phase of the carrier chrominance signal and a second sampling signal which is of a sampling phase opposite to that of the first sampling signal and to form baseband signals conforming to a color signal by using the first and second sampling signals. This arrangement enables the device to process the color signal without causing any signal deterioration that tends to result from DC fluctuations of the carrier chrominance signal.

Control circuitry is provided for controlling a multiplexing ratio of the first and second video signals in the multiplexing circuitry. A display is provided for simultaneously displaying at least a part of a video image which corresponds to the first video signal, and also for displaying a state of the multiplexing operation being performed by the multiplexing circuitry under the control of the control circuitry. Preferably, only a peripheral portion of the image is faded in the view finder. Alternatively, a bar graph on the side of the image in the view finder indicates the degree of fading the image is subjected to.
