Abstract
The present invention provides a system and method for converting color data from a higher color resolution to a lower color resolution. Color data is converted by first receiving a plurality of bits representing color data for an image. Next, a subset of pixels represented by the plurality of bits is selected. The color data for each pixel within the selected subset is then divided into least significant bits and most significant bits. Next, the least significant bits for each pixel within the selected subset are compared to a corresponding value in a lookup table. Finally, for each pixel within the selected subset, if the least significant bits are greater than the corresponding value in the lookup table, then the most significant bits are incremented.
