The facsimile apparatus comprises a control portion for performing control of the whole of the facsimile apparatus, an operation portion, a display portion, a RAM for image memory, a ROM for storing programs and data, a communication control portion for performing connection to the other facsimile, a JPEG coding portion for coding a transmitting color original document, a monochrome coding portion for coding the transmitting monochrome original document, and an original document reading portion. The facsimile apparatus converts the color original document to the monochrome original document when transmitting the color original document in monochrome and adds the message indicating that the color original document was transmitted in monochrome to the color original document when the facsimile apparatus tries to transmit the color original document and the other facsimile declares that the other facsimile has only an ability of receiving the color original document in monochrome.

1. Field of the Invention
The present invention relates to a color image transmitting apparatus having a function for transmitting and receiving a color document.
2. Description of the Related Art
Other and further objects, features, and advantages of the invention will be more explicit from the following detailed description taken with reference to the drawings wherein:
FIG. 1 is a simplified schematic block diagram showing electric configuration of a facsimile apparatus according to an embodiment of the invention;
FIG. 2 is a sequence diagram explaining signals flowing between apparatuses in processing of transmitting the image data performed by the facsimile apparatus according to the embodiment of the invention;
Now referring to the drawings, preferred embodiments of the invention are described below.
The following description will describe the color image transmitting apparatus according to embodiments of the invention with reference to the accompanying drawings. FIG. 1 is a block diagram showing electric configuration of the color facsimile apparatus according to an embodiment of the invention. In FIG. 1, the facsimile apparatus according to the embodiment comprises a control portion 101, an operation portion 102, a display portion 103, a JPEG (Joint Photographic Experts Group) decoding portion 104, a monochrome decoding portion 105, a RAM (Random Access Memory) 106, a ROM (Read Only Memory) 107, a printing portion 108, a communication control portion 109, a JPEG coding portion 111, a monochrome coding portion 112, a monochrome conversion information adding processing portion 113, a monochrome conversion portion 114, and an original document reading portion 115.
The control portion 101 comprises CPU (Central Processing Unit) and controls operation of the facsimile apparatus. The operation portion 102 is composed of various operation keys, switches and the like. The display portion 103 consists of a liquid crystal screen and the like. A user's operation is accepted via the operation portion 102 and the display portion 103. The original document reading portion 115 is provided with a line sensor such as a CCD (Charge Coupled Device) image sensor or a CIS (Contact Image Sensor) and reads an image of a transmitting original document placed on an original document table or a sheet feeder (not shown.)
