Patent ID: 7636485

Claim:
A method for enhancing the appearance of teeth and eyes in a face appearing in a digital image, while balancing their color and uniformity, said method comprising the steps of: acquiring an input digital image having pixel values representative of teeth and eye regions of a face contained in the image from a digital image source; determining a preferred color for the teeth and eye regions, the preferred color for the teeth and eye regions being difference from the color of the teeth and eye regions in the input image; calculating a difference between each pixel value of the input digital image and a mean color value determined from the pixel values of the input digital image with a digital processing unit; providing an enhanced digital image of the teeth and eyes by combining: a) a scaled combination of said difference; and b) the preferred color for the teeth and eye regions with the a digital processing unit, whereby the mean and variance of the color distributions of the pixels of the teeth and eyes in the enhanced digital image are shifted from the input image.
