US 2016/0110845 A1 · METHOD FOR ENHANCING COLORS OF IMAGE AND SYSTEM THEREOF

Abstract

A method and a system for enhancing colors of an image are disclosed. The method comprises: converting the color components in an RGB color space of each pixel in an image into a hue component, a saturation component, and a value component in an HSV color space of the pixel; stretching the saturation component when it is greater than 0 and smaller than 1; converting the hue component, the stretched saturation component, and the value component into an enhanced red component, an enhanced green component, and an enhanced blue component in the RGB color space. Through the method, the phenomenon of color shift can be prevented, thus enabling the image to be brighter and vivider. Hence, the viewers' visual experience can be improved. The method can relieve the problems of color shift and picture washout.

A method for enhancing colors of an image, comprising the steps of:

extracting a red component, a green component, and a blue component in an RGB color space from each pixel in the image, successively;
converting the red component, the green component, and the blue component into a hue component, a saturation component, and a value component in an HSV color space of the pixel;
judging whether the saturation component is greater than 0 and smaller than 1;
stretching the saturation component to obtain a stretched saturation component, if the saturation component is greater than 0 and smaller than 1;
and
converting the hue component, the stretched saturation component, and the value component into an enhanced red component, an enhanced green component, and an enhanced blue component in the RGB color space.
