Abstract
Image signals are converted from one color format to another using a lookup table based on interleaved indices generated from the components in the first color format. In a preferred embodiment, image signals in a YUV format are converted to image signals in a CLUT format by interleaving bits from the U and V components and appending bits from the Y component. By interleaving the U and V components, cache efficiency is improved when color conversion is implemented on a general-purpose processor with limited on-chip cache.
