A coding method for a multilevel-gradated picture signal is disclosed, in that a series of binary codes obtained by processing a multilevel-gradated original picture signal for binary representation are segmented every predetermined number n of picture elements on each scanning line to form blocks, respectively capable of assuming value '0' to '2n-1'; and the value of a block having changed its value and its position on the scanning line are encoded so as to be reproduced on the reproducing side.
