Abstract
A method for improving image contrast for a display apparatus obtains a frame of image data having one or more code values for each pixel in the frame of image data, analyzes the frame of image data to identify a distribution of dark regions therein. The method further adjusts at least one of the one or more code values for the frame of image data according to the distribution of dark regions in the frame of image data and attenuates a brightness level available for the image frame according to the distribution of dark regions in the frame of image data.
