Image signal encoding method and system

摘要

An encoding/decoding method for carrying out conversion between run lengths and corresponding run length codes is provided. The run length codes has a format including a first part for storing first information and a second part for storing second information. The first information indicates the length of the code and the second information indicates the corresponding run length. The total number of bits of each of the run length codes is set as an integral multiple of a predetermined number of bits. The present encoding/decoding method is suitable for use in an image processing system, such as a facsimile machine.
