Abstract
Abstract It is provided an image communication apparatus which comprises multi-level generation section for generating multi-level data from received image data, color conversion section for color-converting the multi-level data from the multi-level generation section, and setting section for setting a single color mode, in which the received image data is dealt with as single color data irrespective of the color conversion section, when it is determined by communication protocol that the communication mode is the single color mode, so as to ensure satisfactory communication even with a single color image.
