Abstract

In processing a video signal, vertical correlation is utilized between video signals of successive line intervals. Video signals from the two line intervals are examined, their existences, polarities and magnitudes between them. If both signals exist with the same polarity, a smaller signal in magnitude is derived at a system output and otherwise no signal appears at the output. This system can be applied to a color television camera circuit.
