ABSTRACT:
This invention is directed to reducing the size of the memory required to store correction information, by defining the two-dimensional non-uniformity characteristics in terms of two functions that are orthogonal. The orthogonal correction functions are stored in separate memories. During a scan, a pixel counter addresses the X memory while a line counter addresses the Y memory. The correction factors thus obtained are applied sequentially to correct the pixel data value at the current X and Y coordinates.
