Abstract
A compressor can compress an image by reducing the amount of data while preserving the information. Some compressors use run length coding wherein image data is converted into a series of run length code words. The efficiency of run length coding can be increased with the introduction of differential run length code words. The differential run length code words can augment the original set of run length codes. Differential run length codes vary from current run length codes by encoding runs of differences.
