MAPPING AN INPUT COLOR VALUE IN AN INPUT COLOR SPACE TO AN OUTPUT COLOR VALUE IN AN OUTPUT COLOR SPACE

摘要

Provided are a method, system, and article of manufacture for mapping an input color value in an input color space to an output color value in an output color space. A lookup table in a computer readable medium maps an input value having color components in an input color space to an output color value in an output color space. The lookup table has n number of possible values for a fixed color component in the input color space and less than n number of possible values for t color components in the input color space. An input value in the input color space is received and a determination is made of surrounding input values in the lookup table surrounding the input value in a t dimensional space, wherein each surrounding input value has a same value for the fixed color component. A determination is made from the lookup table of surrounding output values in the output color space to which the determined surrounding input values map. The determined input and output surrounding values and the input value are used to estimate an output value in the output color space for the received input value in the input color space.
