Abstract
A video noise reduction system for incoming video information from a plurality of picture points. A first processor is capable of synthesizing each picture point from incoming picture point information from adjacent picture points to provide noise reduced picture information. A store is provided for storing picture information from at least one frame and a second processor is capable of synthesizing each picture point from incoming and stored information from a corresponding picture point from a current and earlier frames to effect noise reduction. A detector is provided to detect any movement between pictures to allow processing by the first processor when movement is occuring and from the second processor when no movement is occuring. A third processor may be provided to allow synthesizing from adjacent picture points from current and earlier pictures to effect noise reduction when the picture content is detected to be stationary and has only low frequency components therein.
