ABSTRACT:
A video signal amplitude registration system for a television camera is provided in which the video amplitude of two or more related video signals derived from scanning a common reference are compared with a rising ramp voltage so as to generate a control voltage proportional to the misregistration of the video signal amplitudes at both the black and white signal levels.
