Abstract
A facsimile signal coding system, in which a facsimile signal is divided into a plurality of scanning line groups each including a predetermined number of scanning lines. A substantially central one of the scanning lines of each group is encoded by a coding method without referring to information of a scanning line adjacent to the central scanning line. Information of the remaining lines above the central scanning line is sequentially encoded upwardly from the central scanning line using information of the just precedently encoded line as reference information. Information of the remaining lines below the central scanning line is sequentially encoded downwardly from the central scanning line using information of the just precedently encoded line as reference information.
