Disclosed are a monochrome facsimile apparatus capable of supporting
communication of color information in sYCC color space, and a
color-information communication method that uses this facsimile
apparatus. If a compact flash card has been inserted into the monochrome
facsimile apparatus, which is capable of communicating color file
information, the facsimile apparatus notifies the transmitting side, by
prescribed bits of the FIF of a DIS signal, that it has a function for
receiving JPEG-coded information, lacks a function for receiving
full-color information in Lab color space, and has a function for
receiving full-color information in sYCC color space. If the facsimile
apparatus senses, by prescribed bits of the FIF of a DCS signal, that a
designation to transmit full-color information in sYCC color space has
been received from the transmitting side, then the facsimile apparatus is
allowed to receive color information, which is then stored on the compact
flash card without being printed, by information receiving means having
the function for receiving JPEG-coded information and the function for
receiving full-color information in sYCC color space.
