ABSTRACT:
A coding method for facsimile signals in which a binary facsimile signal is divided into fundamental picture elements sampled every N picture elements and elemental picture elements lying between adjacent ones of the fundamental picture elements. The fundamental picture elements are sequentially encoded for each succession, whereas the elemental picture elements are encoded only at required ones to effectively reduce the transmission time.
