Abstract

A method for RGB data conversion includes the following steps: A) converting input values of RGB to an HSV color space; B) adjusting saturation values and/or brightness values on the condition that hue values of the HSV color space are unchanged; C) calculating color-enhanced values of RGB base on the hue vales, the saturation values and the brightness values after the step B). The present invention also provides an apparatus for RGB data conversion. In the method and apparatus for RGB data conversion of the present invention, the color quality of the display panel is improved by increasing the color saturation and/or brightness.

First claim

What is claimed is:

1 . A method for RGB data conversion, comprising the following steps:
A) converting input values of RGB to an HSV color space; B) adjusting saturation values and/or brightness values on the condition that hue values of the HSV color space are unchanged; and C) calculating color-enhanced values of RGB base on the hue vales, the saturation values and the brightness values after the step B).

2 . The method as claimed in claim 1 , wherein in the step B) the saturation values are adjusted by formula 1 and/or the brightness values are adjusted by formula 2,
