    • 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.
    • 在用于处理传真图像的MR编码操作中,判断变化像素“a1”,“a2”,“b1”和“b2”之间的关系,然后在执行水平模式和垂直模式的处理操作之后,确认 做出是否必须重新检查改变像素“b1”和“b2”。 当新检测不需要改变像素“b1”和“b2”时,在随后的编码操作中采用在前一编码操作期间获得的改变像素“b1”和“b2”。 结果,可以省略获得像素中的变化点的操作,从而可以实现高速编码处理。
