Methods, apparatus and computer readable medium are described that
compress and/or decompress digital images in a lossless or a lossy
manner. In some embodiments, a display controller may quantize pels of a
digital image and may identify runs of successive quantized pels which
are equal. The display controller may generate a symbol to represent an
identified run of pels. The symbol may comprise a run length and a
quantized pel that may be used to reconstruct the run of pels. The symbol
may further comprise an error vector for each of the pels of the run that
may be used to further reconstruct the run of pels.
