ABSTRACT:
Transmission of an entered image, in the color mode, without passing memory means, and, in the monochromatic mode, after storage once in the memory means allows to avoid unnecessarily long image entering operation for image reading in case of monochromatic images, and also to provide an image transmitting apparatus of a smaller size and a lower cost in comparison with the conventional color communication apparatus. Also processing of a received color image without passing memory means and of a received monochromatic image through the memory means allows to store such monochromatic image even in the absence of a recording material and to provide an image receiving apparatus of a smaller size and a lower cost in comparison with the conventional color communication apparatus.
