Noise reduction circuit.

摘要

The present noise reduction circuit comprises a first circuit (20, 22) for extracting a relatively high frequency component of an input singal and amplitude-limiting a component of said amplitude-limited high frequency component exceeding a predetermined level, a second circuit (2l) for delaying said input singal such as a video signal by a predetermined time, and a third circuit (24) for adding outputs of said first and second circuits and outputting an added result as an output of said noise reduction circuit.
