Abstract
Facsimile transmission arrangement for documents which are divided into document lines and which contain photographs in addition to text. The text zones of a document line are subjected to a normal run-length coding. The photo zones are subjected to a photo coding. Therein, areas which have a uniform grey tone are first converted into a sequence of binary '0' and '1' elements which succeed each other in a regular alternation. Thereafter a first and a second code word are generated which indicate the number of binary '0' elements and the number of binary '1' elements, respectively of the sequence. These code words are transmitted to the receiver either directly or after having been converted into a Huffman code.
