Patent ID: 7492394

Claim:
A method of correcting erroneous image signals from a multicolor pixel array, the method comprising the steps of: providing a high signal and a low signal based on an image signal of a previously processed pixel of the multicolor pixel array, the previously processed pixel having a single color designation, said image signal of said previously processed pixel being an image signal from a set of image signals that represents a single captured image of a scene of interest, said high signal and said low signal defining a signal range about said image signal of said previously processed pixel; and digitizing an analog signal of a current pixel of the multicolor pixel array, which is separated from the previously processed pixel by a same predetermined of pixels as other processed pixels in the multicolor pixel array, using said high and low signals as references to derive a digitized signal of said current pixel within said signal range, including limiting said analog signal of said current pixel by said high and low signals, said analog signal of said current pixel being another image signal from said set of image signals.
