Abstract
A system that stores a color management transform, typically using a grid table, where one or more of the input channels represents parameters used to control the reproduction of the conventional color image channels. The invention augments the existing grid-table based transform structure with additional channels to control the operation of the color models involved. These additional channels are not the conventional calorimetric or colorant image channels such as red, green, and blue, but are to control other aspects of the color transformation, such as exposure level or saturation. The augmentation also includes identification information that identifies the type of control (exposure, grey component replacement, etc.) the extra channels provide.
