Method for increasing color saturation of red, green, blue values of pixel of digital image, involves increasing color saturation of pixel of image based on calculated maximum increases of saturation factor

摘要

The method involves calculating a luminance value based on red, green, blue (RGB) values of a pixel, and calculating a maximum increase of saturation factor (SF-maxH) of color saturation on the basis of highest values of the RGB and luminance value. Another maximum increase of saturation factor (SF-maxL) of the color saturation is calculated on the basis of the lowest of the RGB values and the luminance value, and the color saturation of the pixel is increased based on the maximum increases in saturation factor. An independent claim is also included for a device for increasing color saturation of RGB values of a pixel of an image.
