ABSTRACT:
An image communicating system such as a facsimile for transmitting and/or receiving image data. This system comprises a reader to read an original image at the first resolution, a coder to code the image signal of the first resolution obtained by the reader, an image memory to store the signal coded by the coder, a converter to convert the signal read out from the image memory to a signal of a recording resolution on the reception side, and a transmitter to transmit an output signal of the converter. The image memory is commonly used as a reception memory, a broadcasting transmission memory, and a retention memory for multicopy, so that the memory capacity can be reduced. The pixel density of the transmitting image data is converted in accordance with the recording pixel density on the reception side. Thus, the image data of a high quality can be derived and printed by a high-speed laser printer on the reception side without changing the image size.
