Abstract
Disclosed is an automatic noise removal device which detects an amplitude of noise contained in a high frequency component of a picture signal during a flyback period of the picture signal, produces a threshold level depending on the detected signal, and removes from a video signal a high frequency component of the picture signal contained in a picture signal at a lower level than the threshold level.
