Title: Facsimile equipment
Inventor: HIDAKA YASUHIRO
IPC: H04N1/00
Filed: 1994-02-21
Abstract: PURPOSE:To shorten the communication time of pixel data by sending previous line substitution execution information consisting of a smaller number of bits when pixel data of one read line match a previous line which is already sent. CONSTITUTION:After communication protocol ends, pixel data of a set document are read out (ST1) and stored in a memory 13 (ST2). At this time, the pixel data of one line are read and stored in the memory 13 (ST3). The currently read pixel data are compared with pixel data which are read out one line before and stored in the memory 13 (ST4) to judge whether or not the pixel data of both the line match each other (ST5). When it is judged that the read pixel data are the same as the pixel data of the last line, the pixel data are not transmitted and the previous-line substitution execution data are sent (ST8). Consequently, the previous line substitution execution information consisting of a smaller number of bits than the encoded pixel data can be sent, so the transmission time is shortened.
