ABSTRACT:
In a method of processing a video signal, including the step furnishing (11) a filtered signal in response to the video signal, the filtering is adapted (22) in dependence upon a statistical property (AC) of a modification effected by the filtering in a previous time interval of the video signal. Preferably, the filtering is adapted (22) in dependence upon an average modification (AC) effected by the filtering in a previous field or frame of the video signal.
