Color image display apparatus and method therefor

摘要

A single frame buffer is used in displaying on a display both an image from a first-type image source specified by a red-green-blue (RGB) value and an image from a second-type image source specified by an index value for a look-up table. A data-type buffer stores a data-type indicating whether each value stored in the frame buffer is the RGB value or the index value corresponding to each pixel on the display. A buffer writer may compress the RGB value. A buffer reader may decompress the RGB value from the compressed RGB value.
