<p> A variational model for spatially dependent gamut mapping is described that includes inputting a gamut constraint (110), choosing a one dimensional gamut projection scheme, including selecting a transform color coordinate system (115), computing transform equations (120), and verifying gamut conditions. The model also includes inputting an original image to be rendered (135), where the original image is in a given color coordinate system, transforming the gamut constraint (125), the image (140), and the transform equations to the transform color coordinate system, whereby a three dimensional function is transformed into a one dimensional quadratic functional, finding (150) a minimum solution to the functional, and transforming (155) a projected image in the transform color coordinate system into a color coordinate system of a rendering device.</p> |
