Abstract
In a video noise reducer, where pixel information is recursively filtered, with recursion being disabled at a disjuncture (caused by motion, planning, shot-change or otherwise), recursively filtered pixel information prior to disjuncture continues to be output until pixel information following the disjuncture has been recursively filtered to an appropriate degree of noise reduction.
