Abstract

PURPOSE:To facilitate automatic correction and to prevent the generation of an error signal by obtaining a correcting signal by detecting the phase difference between output pulses of a reference channel and another channel, and resetting the output of a phase comparator in every constant period. CONSTITUTION:Video input signals of channels G and R, after being preprocessed, are binary-coded and then windowed by a window circuit 10 with the extracted signal of a detected part. A resetting circuit 11 generates a reset pulse to reset an error signal during the last detection period until the beginning of each period. Processed signals of respective channels free of the error signal are compared by a phase comparator 9 to obtain a control signal for registration correction.
