Abstract
In the processing and transmission of an image, there is generated additional information relative to the transmitting apparatus or to the image signal to be transmitted, then an image signal representing an input binary image and an iamge relative to the additional information is binary encoded, or an input multi-value image signal is multi-value encoded, and the binary encoded image signal and the multi-value encoded image signal added with data relative to the additional information are selectively released. Also in the processing of a received image, a binary encoded image signal or a multi-value encoded image signal contained in the received image signal is decoded, also additional information relative to the received image signal is extracted from the multi-value encoded image signal, and there is selectively released a binary image containing an image according to the image signal obtained by decoding the binary encoded image signal and relating to the additional information relative to the received image signal, and an image containing a multi-value image according to the image signal obtained by decoding the multi-value encoded image signal and an image according to the extracted additional information. Such configuration provides an image communication apparatus capable of maintaining compatibility with a conventional monochromatic image communication apparatus and also adaptable to a color image without image quality deterioration in the associated character information.
