Systems and methods for performing color adjustment of pixels on a color display

摘要

System and methods are provided for performing saturation adjustment of one or more pixels. In one embodiment, an input color value of a pixel is received. The input color value includes an input saturation component. An adjusted color value is extracted from a predetermined look-up table that maps the input color value to the adjusted color value, the adjusted color value having an adjusted saturation component that is different from the input saturation component. The adjusted color value is output.

1. A processor-implemented method for performing saturation adjustment of one or more pixels, the method comprising:
receiving an input color value of a pixel, the input color value including an input saturation component; extracting, using a data processor, an adjusted color value from a predetermined look-up table that maps the input color value to the adjusted color value, the adjusted color value having an adjusted saturation component that is different from the input saturation component; and outputting the adjusted color value; wherein the look-up table is generated through steps of:
receiving an original color value represented in a red-green-blue (RGB) color space;convening the RGB representation of the original color value to a representation in a hue-saturation-lightness (HSL) color space, the HSL representation of the original color value including an original saturation component;generating an intermediate representation in the HSL color space by changing the original saturation component of the HSL representation of the original color value based on a predetermined criterion;converting the intermediate representation in the HSL color space to a final representation in the RGB color space, the final representation in the RGB color space corresponding to a final color value; andstoring a mapping of the original color value and the color value into the look-up table.
