Patent ID: 7813003

Claim:
A method of color conversion, comprising: receiving a RGB color signal of a pixel; and performing a color-space conversion on the RGB color signal for adjusting saturation or hue thereof, wherein luminance compensation is performed on the RGB color signal on which the saturation adjustment or the hue adjustment has been performed, to compensate the luminance of the RGB color signal influenced by the saturation adjustment or the hue adjustment, the saturation adjustment is firstly performed on the RGB color signal, and a first luminance compensation is performed on the RGB color signal on which the saturation adjustment has been performed, to compensate the luminance of the RGB color signal influenced by the saturation adjustment, and the hue conversion is performed on the RGB color signal on which the saturation adjustment and the luminance compensation have been performed to adjust the hue of the RGB color signal, and a second luminance compensation is performed on the RGB color signal on which the hue adjustment has been performed to compensate the luminance of the RGB color signal influenced by the hue adjustment.
