Abstract
A graphical effect having a transformed gamut is disclosed. The method includes predetermining a mapping of an input gamut to a desired output gamut so as to produce a desired artistic effect; and utilising the mapping to map the input image to an output image having a predetermined output gamut; A post processing step of utilization of a brush stroke filter enhances the effect. The output gamut can be formed from mapping a predetermined number of input gamut values to corresponding output color gamut values and interpolating the remaining mapping of input gamut values to output colour gamut values. The interpolation process includes utilising a weighted sum of the mapping of a predetermined number of input gamut values to corresponding output colour gamut values.
