Abstract
A bit train of a plurality of continuous pixels is compressed according to a new run-length compression scheme. In this run-length compression scheme, the run information of one unit of compression includes run-length information indicating the continuous number of the same pixel data blocks, or the number of pixels followed, and pixel data having a two-bit configuration for discriminating three or more colors of the pixels.
