ABSTRACT:
An arrangement which provides for storing a single lookup/bypass bit with each pixel stored in a frame buffer to indicate whether the color format used to display that pixel on the output display is to use the lookup tables, and for storing an indication apart from the frame buffer which to indicate the decode format for the pixels stored in the frame buffer and retrieved for display by programs providing graphics output in different color formats. The arrangement allows fifteen bit color formats to be stored in standard sized frame buffers without the addition of memory devices.
