Abstract
A system for setting up a video camera. A signal processing circuit provides a plurality of signal channels which may be selectively connected to receive the camera output signal. A microcomputer is provided which stores digital correction values corresponding to minimum error values of distinct sub areas of the video signal. An error measuring circuit determines error values between the average value of a video signal taken over distinct sub areas of a television picture and a reference value. Each of the channels are selectively connected to the digital error measuring circuit to detect an error in the video signal passing through a connected channel.
