Abstract:
1. A method of performing color conversion by a color converter included in an imaging device to convert a set of input color values to color values in an output color space for use in printing using said imaging device, the method comprising: receiving the set of input color values by the color converter included in the imaging device; representing an output color in said output color space as a geometric lattice having a plurality of lattice points, each of said plurality of lattice points having an address defined by a particular set of input color values; using the set of input color values with respect to said geometric lattice to determine a set of lattice points that neighbor a point corresponding to said set of input color values to be interpolated; choosing a random number; and utilizing said random number to select a first lattice point of said set of lattice points to provide as a pseudo-interpolated result of said color conversion.
