Video signal processing apparatus for controlling exposure, focus, and white balance for a VTR incorporated in a video camera

Abstract

A video signal processing apparatus for a video camera having a video tape recording and reproducing device integrated therewith. The apparatus includes an automatic phase control (APC) circuit for controlling the phase of a color signal component contained in a video signal, a generating circuit having a microcomputer for generating a control signal for controlling the iris, focus and white balance of a video signal supplied from the video camera, and a digital operation circuit which is commonly used by the APC and generating circuits. The digital operation circuit includes an input device for receiving an output signal from the APC circuit and the video signal from the video camera, a processing device for processing the output signal and the video signal received by the input device, a device for supplying respective processed signals from the processing device to the APC and generating circuits, and a control device for controlling the input device, the processing device and the supplying device.
