Abstract
In an MR coding operation for processing a facsimile image, relationships among changing pixels 'a1', 'a2', 'b1' and 'b2' are judged, and then after performing process operations of a horizontal mode and a vertical mode, confirmation is made whether or not the changing pixels 'b1' and 'b2' must be newly checked. When the changing pixels 'b1' and 'b2' are not required for a new detection, the changing pixels 'b1' and 'b2' which have been obtained during the preceding coding operation are employed in the subsequent coding operation. As a consequence, the operation to obtain the changing points in the pixels can be omitted and thus a highspeed coding process may be achieved.
