Abstract: The present invention relates to the art of color space conversion technique, and discloses a method for processing RGB data and a system for the same. The method comprises: S1: converting input values of three colors RGB into a HSV color space; S2: adjusting a brightness value V while keeping a hue value H and a saturation value S unchanged in the HSV color space; S3: converting the H, S, V values processed by step S2 from the HSV color space to the R, G, B, W color space to display. By converting the RGB color space to the HSV color space firstly, then enhancing the brightness V while keeping H, S unchanged in the HSV color space, and finally converting the HSV color space to the RGBW color space, it can be achieved that the brightness for display is enhanced while better hue, color saturation and natural color transition are maintained at the same time.
