Claim One:
1. A method for reducing correlated noise in image data, comprising: receiving a set of correlated data from an imaging device, the set of correlated data corresponding to a set of two or more correlated image pixels for a present image frame; determining a composite value for the set of correlated data; receiving a prior composite value corresponding to the set of two or more correlated image pixels from a prior image frame; determining a new filtered composite value for the set of two or more correlated image pixels for the present image frame; determining a pixel correction value based upon the new filtered composite value for the set of two or more correlated image pixels for the present image frame; and applying the pixel correction value to the set of correlated data to reduce correlated noise in the set of two or more image pixels for the present image frame.
