Abstract
An automatic registration system for use in a plural pickup tube color television camera comprises an edge detector circuit which provides an edge signal representing the position of an edge of a sharply-edged object; a time difference detector circuit for detecting the difference in time between the scanning of the edge by, for example, a green pickup tube, and that by a red or blue pickup tube, and providing a deflection signal; a multiplier providing the product of the edge signal and the deflection signal as an error signal; a sample hold circuit for providing a misregistration signal, in response to the error signal, having a magnitude and polarity respectively indicative of the degree and direction of misregistration of the pictures of the pickup tubes; and a circuit for correcting misregistration in response to the misregistration signal. The circuit for correcting misregistration can include an up/down counter whose direction of counting is determined by the polarity of the misregistration signal.
