Patent ID: 7903286

Claim:
A method for dynamically converting first color data to second color data using a look-up table, wherein the first color data is a subset of a first color space, and the second color data is a subset of a second color space, the method comprising: receiving at least one first color value in the first color data; identifying at least one look-up table entry needed for converting the at least one first color value; determining if the at least one look-up table entry has been previously calculated; if the at least one look-up table entry has not been previously calculated: (a) calculating a value for the at least one look-up table entry; and (b) storing the calculated value for the at least one calculated look-up table entry; if the look-up table entry has been previously calculated, skipping steps (a) and (b); and computing at least one value in the second color data corresponding to the at least one first color value based on the at least one first color value and the stored value of the at least one look-up table entry.
