Abstract

The present invention comprises of a digital image processing method which simultaneously enhances color saturation and sharpness on a pixel-by-pixel basis directly in RGB color space, the most popular color space used to represent digital color images, and does not cause color hue shifts. The method comprises the steps of: developing a surround function to analyze the local brightness uniformity in a digital image; generating an intermediate image using the brightness uniformity; calculating enhancement values in each of RGB channels of each pixel with a gain function; and adding the enhancement values to the respective RGB channels for each pixel to produce an adjusted digital color image with enhanced color saturation and sharpness.
