Abstract
A memory footprint of look up tables for color transforms can be reduced by separating the look up tables into factors, applying frequency domain transforms, dividing the look up tables into zones, or establishing hierarchical levels with increasing resolution. The methods can be applied to still image or video cameras with limited computation resources that can benefit from reduced memory footprints.
