A method and system for reducing noise in image and audio signals for
processing and output display includes determining noise estimates for a
given signal and performing a noise reduction routine for two adjacent
data in a signal array. By using a predetermined conversion factor and a
permissible delta (deviation) between the two adjacent data, energy may
be shifted from the higher valued data to the lower valued data to reduce
the noise level without changing the total intensity of the signal array
(corresponding to image and/or audio data).
