Abstract
Described herein are technologies for color transformation in a graphics processing hardware using at least two hierarchical one or multi-dimensional lookup-tables (LUT) in order to obtain a minimized overall LUT storage space yet achieves transformation output of desired accuracy. Particularly, a first interpolation of an input signal is implemented using a main LUT and successive interpolations using higher order difference LUTs. Outputs of the first and successive interpolations are then combined to generate a transformed pixel output.
