According to one aspect, there is provided a method of determining if pixel level values of a digital picture image can benefit from an adjustment in levels to enhance the edge appearance of the image. The method involves: (1) locating edges within the image; (2) determining pixel level values across found edges; (3) determining existing overshoot from the pixel level values found at step 2; and (4) determining, based on the overshoot magnitude, if an adjustment in pixel level values will be beneficial to the edge appearance of the image.
