PROCESSOR FOR INCREASING THE RUN-LENGTH OF FACSIMILE DATA Abstract of the Disclosure A facsimile scene typically includes a plurality of lines, each line having a plurality of picture elements (pels). Often, pel signals are adaptable for run-length coding, a run being one or more successive pels having the same brightness level. To increase the length of a run and hence to permit a more efficient use of a transmission link, a processor is disclosed for permuting a measure of the pel signals responsive to a reference signal. Illus- tratively, the reference signal is the pel signal from a previous line. In one exemplary bi-level pel signal embodiment, the measure is the current pel signal. Specif- ically, if the reference pel signal is a logic one, the current pel signal is loaded beginning at one end of a memory; if the reference pel signal is a logic zero, the current pel signal is loaded beginning at the other end of the memory. In a second embodiment, the measure is an error signal for indicating a difference between the reference signal and the current pel signal. But for load- ing the error signal rather than the current pel signal, the operations aforedescribed are again followed.
