Abstract
A process, apparatus, and system for generating and using lookup tables to convert image signals from a multi-component format to a single-index CLUT format for an arbitrary CLUT palette. In a preferred embodiment, lookup tables are generated for an arbitrary CLUT palette and used to convert (with Y, U, and V dithering) three-component subsampled YUV9 video signals to 8-bit CLUT signals.
