摘要: A method is disclosed for determining an adjustment amount to be made input chroma, C in , squeeze the chroma toward a region of preferred pref . This involving first defining change as: ΔC=C −C and weight =Gaussian(C ,C sigma ); luminance L =Gaussian(L ,L hue H =Gaussian(H ,H );. Then, is: Adjust =ΔC*(H *C *L ). An output generated by applying input: out =C
