Abstract
A video noise reduction system including a coefficient modifier for modifying at least a portion of the incoming video information. Video storage is provided to store the modified information and an adder is provided for adding at least a portion of incoming picture information with at least a portion from a corresponding stored picture point from an earlier field. The noise reduced picture information is provided at the store output. The degree of noise reduction may be varied in dependence on movement detected between fields and whether luminance or chrominance components are present.
