Facsimile encoding communication system

摘要

Binary 0's and 1's from picture elements in each line are counted with respect to each mode determined by adjacent picture elements to form symbol patterns determined by both the counts and the information content of a memory. Each pattern is encoded into a code word to be transmitted having a bit number determined by the arrangement of binary symbols included in it. Also the code words can be transmitted on the basis of address numbers of picture elements, starting with the output from a coder associated with a mode having the two-valued signal with the least address number.
