The color to be colored in the transmission message is extracted from the color conversion table 9 indicating the color information corresponding to one of the various information unique to the various messages determined by the determination unit 8, and the conversion execution unit 10 converts the color of the message into the extracted color. Convert.

A header character string creating unit 11 creates a header character string for each page when adding a header to the upper part of the image data to be transmitted, converts the header character string into image data, and combines the image data with the transmitted image data. It is. In some cases, the color conversion table 9 is referred to when converting the header character string into image data.

Next, the operation when the conversion execution unit 10 converts the base color of a message will be described with reference to the flowchart of FIG. I will explain it.

FIG. 2 is a flowchart showing the operation of the transmission / reception control unit 5. First, from the main control unit 7,
List of message numbers of messages to be sent, destination user I
D (hereinafter UID), destination telephone number, registrant UI of the message
A transmission request including information specific to a transmission message such as D is received (step 101).

Upon receiving the transmission request, the transmission control unit 5 acquires a pointer to image data corresponding to the received list of message numbers from the message storage unit 6 (step 10).
2). In the message storage unit 6, one-to-one correspondence with the given message number is performed.
And returns a list of pointers to the image data to the transmission control unit 5.

The transmission / reception control unit 5 having acquired the pointer of the image data to be transmitted passes a call request including the transmission destination telephone number to the line control unit 4. (Step 103).

Upon receiving the call request with the transmission destination telephone number, the line control unit 4 performs a call process on the line network 3 and secures a line with the transmission destination terminal. If the line reservation fails, the transmission process is stopped. After securing the line, communication negotiation is performed with the transmission destination terminal. At this time, information is obtained as to whether the other party facsimile terminal is a terminal capable of receiving a color image. After the end of the negotiation, a response to the call request accompanied with information on whether the other terminal can receive the color image is returned to the transmission / reception control unit 5.

Upon receiving the response to the call request, the transmission control unit 5
It is determined whether the destination terminal is a terminal capable of receiving a color image (step 104). If the destination terminal is not capable of receiving the color image, the page is determined from the list of pointers of the image data acquired in step 102. Image data is acquired for each page, and an image transmission request accompanied by a pointer to image data for each page is passed to the line control unit 4 (step 111).

The above step 111 is repeated for each page (step 112), and when transmitting a plurality of messages, it is repeated for each message (step 113).

If the destination terminal can receive the color image, it sends a message type determination request with a message number to the message type determination unit 8. The various determination unit 8 acquires a message type ID corresponding to the message number from the internally held data,
A response to the message type determination request with the obtained message type ID is returned to the transmission control unit 5. The message type ID is one-to-one with the message type
(Step 105).

The transmission / reception control unit 5 having acquired the message type ID
Refers to the message type color conversion table 9 and acquires the color corresponding to the message type ID of the message to be transmitted (step 10).

A coloring method is also possible. FIG. 15 shows an output image by facsimile in this case.

The transmission / reception control unit 5 receiving the response to the color conversion execution request passes the page transmission request including the pointer to the transmission image data to the line control unit 4 and checks whether the next page exists in the image data. Confirm (Step 10
9). If the next page exists, the above steps 107 to 109 are repeated for each page, and when the hour page no longer exists, it is confirmed whether image data of the next message to be transmitted exists (step 110). .

If the next message exists, the above step 10 is executed.
5 to step 110 are repeated for each message,
The process ends when the next message no longer exists.
