Novel methods and systems for image processing and gamut mapping are disclosed, where image parameters in a first color space are transformed into parameters in a second color space. In one example, the gamut mapping system processes the image parameters in a parametrized space using substantially rectangular spectral functions. In another example, the gamut mapping system processes the image parameters in a parametrized space using smooth spectral functions. The smooth spectral functions may include a linear combination of functions, including at least a cosine square function. Image parameters may include an intensity parameter, a center wavelength parameter, and a saturation parameter. |
