Abstract: A method for performing a modification of the color saturation of at least one pixel of an image involving: determining, based on pixel values of a first pixel, at least one of a color saturation value, luminance value and hue value corresponding to said first pixel; determining, based on said at least one value, a saturation factor; and modifying the color saturation level of said first pixel based on said saturation factor.

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.
