Abstract
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.
