Abstract
A method for adjusting a degree of saturation of a target pixel is provided. In a first color space, the target pixel is represented by a brightness factor and a set of color factors. Based on the set of color factors, the method first generates an original saturation and a hue factor. Then, selectively according to the brightness factor, the hue factor, and the original saturation, an adjusting gain is generated. The method, according to this invention, multiplies the original saturation by the adjusting gain to generate a new saturation for the target pixel.
