Abstract
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).
