In typical image processing circuitry, used in scanning environments, windowing (the application of an image processing function to a particular group of pixels) is controlled either through a series of counters, comparators, and effect storage blocks used to generate rectangular windows or through a large block of memory used as a mask to be applied over the input video to determine the required effect for a particular pixel. Neither of these approaches represent an ideal solution for the generation of window effects in a scanner environment.
