The circuit includes circuit parts each with a delay circuit having different delay times in accordance with a kind of correlation existing in information contents of an input video signal and a control circuit having detecting circuits and a control signal supplying circuit. Each detecting circuit detects large amplitude components in the output signal of a first subtractor of a corresp. noise reduction circuit part. The control signal supplying circuit supplies the output signal of the detecting circuit as a control signal to limiter circuits of the noise reduction circuit parts other than the corresp. circuit part.
