ABSTRACT:
An apparatus and method for updating a color look up table and expanding video data for use in various applications such as a multimedia computer. The color look up table updating scheme permits selective updating of one entry in the table or up to all of the entries in the table. Updating of the color look up table is preferably performed during the horizontal blanking period. The table may be comprised of two buffers, and a combined output of these two buffers further enhances a multiplicity of colors available to a user.
