ABSTRACT:
Image data in an initial color format (e.g., subsampled YUV9 data) is color converted to a selected RGB16 color format by executing compiled computer program code. The same compiled computer program code can be used to convert the image data in the initial color format into image data in any of two or more different RGB16 formats. In a preferred embodiment, lookup tables (configurable during run-time processing) are used to make the color conversion processing more efficient. The selected RGB16 color format can be changed during run-time processing, in which case certain lookup tables are reinitialized for the newly selected RGB16 format.
