Circuitry for image processing

摘要

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.

1. A method, comprising:
increasing color saturation of RGB (red, green, blue) values of pixels of an image by, calculating a luminance value (Y) based on RGB values of a first pixel; calculating a first maximum increase (SFmaxH) of color saturation based on a highest of said RGB values and on said luminance value; calculating a second maximum increase (SFmaxL) of color saturation based on a lowest of said RGB values and on said luminance value; increasing the color saturation of said first pixel in the RGB color space based on said first and second maximum increases; and modifying the increased color saturation of the first pixel in the RGB color space based on a modification defined in the HSV (Hue, Saturation, Value) color space.
