Abstract
Data pixels defining first and second images are stored in first and second image buffers, respectively. A second image coordinate location within a display matrix of a display device having display pixels that have multiple stable states is stored in a memory. Data pixels of the first image are read from the first image buffer. If a data pixel read from the first image buffer is within the second image coordinate location, a data pixel from the second image buffer corresponding with the data pixel read from the first image buffer is read, and the data pixel read from the second image buffer is combined with the corresponding data pixel read from the first image buffer to generate a derived data pixel. Synthesized pixels corresponding with at least each of the data pixels of the second image are generated. The synthesized pixels respectively include the derived data pixels.
