Abstract
By converting a first color space to a second color space, using a two-dimensional lookup table in said second color space, and converting from said second color space to said first color space, it may be possible to use one or more two-dimensional lookup tables (LUTs) to do a task conventionally handled by three-dimensional lookup tables. This may reduce storage requirements and memory bandwidth requirements in some embodiments. In general a color pixel with N color components can be processed with n number of M dimensional LUT where M<N and n is some chosen positive integer number.
