Abstract
A system and method provides the necessary image information to enable tonal correction for independent regions of a compound document. A scanner scans an image and generates image data. A histogram circuit, connected to the scanner, generates histogram data from the image data for a predetermined number of regions corresponding to the image. A windowing circuit, operatively connected to the scanner and in parallel with the histogram circuit, generates a window corresponding to an independent area of the image that requires image enhancement and an association circuit associates corresponding histogram data with the generated window. The associated histogram data and window are used by an image enhancement process to modify the image data to provide a more desirable reproduction of the scanned image.
