PURPOSE:To simplify a color signal processing circuit in a finder and to reduce the shape, weight, etc., of the finder, by providing a phase detector for detecting a color subcarrier signal in a color video camera to supply a carrier color signal and the color subcarrier signal to an electronic view finder. CONSTITUTION:A burst gate circuit 60 and phase detector 61 are installed to the output side of a filter which is installed in a color signal processing circuit, and a detector 61 compares phases between the output of a frequency divider 24 and a burst signal from a tape recorder picked up out of the circuit 60, to control the output signal of 4fsc transmitter in phase in a video camera. A oscillator 23, the frequency divider 24 and the detector 61 constitute an APC group to control an output signal in phase by the burst signal included in external signals out of a composite video signal input terminal 35. The output signal supplies a carrier color signal and color subcarrier signal to a color electronic view finder 46, and thus the constitution of a signal processing circuit is simplified. |
