Abstract
A method of increasing the color saturation of the RGB values of at least one pixel of an image, the method involving: calculating a luminance value based on RGB values of a first pixel; calculating a first maximum increase of said color saturation based on the highest of said RGB values and on said luminance value; calculating a second maximum increase of said color saturation based on the lowest of said RGB values and on said luminance value; and increasing the color saturation of said first pixel based on said first and second maximum increases.
