Abstract
A system and method generates a histogram of a scanned image by determining a number of pixels of the image to be scanned to generate the histogram. It is then determined whether the determined number of pixels is less than or equal to a capacity of a histogram buffer. The image is scanned to generate pixels having grey values associated therewith and a portion of the generated pixels is stored in the histogram buffer if it is determined that the number of pixels exceeds the capacity of the histogram buffer, thereby generating a histogram of the image.
