Abstract

Abstract PURPOSE:To decrease generating code bits and shorten the required transmission time by detecting the skip line immediately after the line having a variation point, and generating a skip code in coding the skip line. CONSTITUTION:A run-length detection circuit 1 inputs a picture signal 100 serially, which is obtained by scanning an original, and when a variation point requiring signal 106 changes from an H level to an L level, the variation point detection begins. When the variation point is detected, a variation point detection signal 101 is outputted an MR code circuit 3 and a decision circuit 2, and when the picture signal processing of the one line has terminated, a line terminating signal 102 is outputted to the MR code circuit 3 and the decision circuit 2. When a totally- white line is inputted immediately after the line having the variation point, the decision circuit 2 decides this line as a skip line, and a skip line signal 105 is outputted to the MR code signal 3 and a skip controlling circuit 4. The skip controlling circuit outputs a skip code 107 based on this signal 105, and the skip operation is executed.
