ABSTRACT:
A noise reducer wherein, depending upon the magnitude of a difference signal between an input television signal at the present time and a television signal recorded in a frame memory and with noise reduced, the mixing ratio between the present-time input signal and the television signal obtained from the frame memory is varied, and a part of the mixed signal is applied to the frame memory while the other part is used as a television signal with noise reduced; a noise reducing system wherein, in order to make the reduction of noise possible even for a moving object, a movement of a picture in one frame time is detected, the output of the frame memory is compensated for with the movement, and depending upon the magnitude of a difference signal between the present-time input television signal and the movement compensated output signal of the frame memory, the mixing ratio between the present-time input television signal and the compensated output signal of the frame memory is varied.
