ABSTRACT:
What is disclosed is a method for determining a hue adjustment to an input hue, Hin, to squeeze the input hue toward a region of preferred hue, Hpref. The method involving defining a change in hue as: ΔH=Hin−Hpref; defining a hue weight as a Gaussian: Hweight=Gaussian(Hpref,Hsigma) wherein the Gaussian function can be alternatively replaced by one of either the sum of two Gaussians or a Gaussian convolved with a Rect function; defining an amount of hue adjustment as: HAdjust=ΔH*Hweight. Then, an output hue is generated by applying the adjustment such that: Hout=Hin−HAdjust.
