Abstract
A method for reducing a bit depth of an image to reduce storage memory, the method comprises the steps of creating a histogram of an image; modifying the histogram so that a maximum slope of a to-be-calculated cumulative histogram will be no greater than substantially 1.0; (c) calculating the cumulative histogram from the modified histogram; and (d) interpreting the cumulative histogram to give a desired bit depth reduction.
