Claim Text:
1. A method for image color enhancement, comprising steps of: a) collecting color components of an image, and converting the color components from a RGB space into a HSV space, and obtaining parameters in the HSV space as hue, saturation, and value respectively; b) performing gain operations selectively on the saturation and the value by judging the saturation in the HSV space; and c) converting the obtained parameters in the HSV space back into the RGB space, wherein the step of b) comprises judging whether the saturation value is equal to zero, wherein a first gain function used for the gain operation in the step b) is an exponential function and is expressed as a formula S wherein a second gain function used for the gain operation in the step b) is an exponential function and is expressed as a formula V
