Abstract
A camera system having an analog interface through which any one of camera head units can be selectively connected to a chrominance/luminance signal generator unit. The camera head unit includes an image pickup device, a drive circuit, and a synchronizing signal generator circuit. The chrominance/luminance signal generator unit includes a camera processor circuit, a Y/C separation/demodulation circuit, and a signal identifying circuit. Synchronizing signals are added to the output signal from the camera head unit, and used for the kinds of signal to be discriminated. The camera processor and the Y/C separator/demodulator are switched in response to the results from the identifying circuit. Therefore, the signals from a plurality of camera head units can be switched and processed by a single signal processor, or chrominance/luminance signal generator unit.
