Patent ID: 6950110

Claim:
A color conversion system for converting a first color value to a second color value, the system comprising: a first module comprising an input coupled to the first color value, a lookup table coupled to the input and to an interpolator, the lookup table comprising a plurality of entries, each entry associating a first value to a second value, the interpolator coupled to an output; and a second module comprising a decompressor comprising an input coupled to the output of the first module, and an output providing the second color value; wherein the lookup table is created by: identifying an entry that has a second value equal to a predetermined value, and that is adjacent an entry having a second value equal to a number other than the predetermined value; compressing the second values of a first plurality of the entries to form corresponding intermediate values; and replacing the second value of the identified entry with a value determined by a regression that includes the intermediate value of the adjacent entry.
