BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram of the entire facsimile apparatus according to this embodiment. As shown in FIG. 1, the facsimile apparatus includes a system control unit 10 that performs control processing of the entire facsimile apparatus and processing of image information, and a program RO that stores programs and information for executing communication control.

An analog public line control unit 24 for controlling the above is provided, which are mutually connected by a system bus 26.

The control programs and information stored in the program ROM 12 are classified as follows according to each functional block. That is, a division information table 3 in which information indicating how the divided image information sent from the other device is divided is shown for each document size and resolution.

Protocol control section 34, system control section 36 for causing the system control section 10 to execute control of the entire system, and image information composition processing of the divided image information sent from the other device by referring to the division information table. Image information synthesis processing unit 38 to be executed by the system control unit 10
It has.

Further, the input unit 22 is connected to a scanner (not shown) that outputs image information of the transmission document by scanning the transmission document while irradiating it with light and quantizing the reflected light. Then, this image information is input to the facsimile apparatus via the input unit 22. This scanner can also scan large documents such as A0, A1, and A2 sizes.

The facsimile apparatus having the above-mentioned structure is connected to the partner machine of the facsimile apparatus having the same structure as described above through a line.

Next, each of the three processes of the image information dividing process, the communication protocol control, and the image information synthesizing process in the facsimile apparatus having the above configuration will be described.

First, the flow of the image information division processing will be described with reference to the flowchart of FIG. In this image information division processing, for example, the image of an A0 size original document as shown in FIG. 3A is compressed and expanded as shown in FIG. 3B.
Is executed when the size exceeds the maximum size that can be processed. It should be noted that FIG. 3 deals with the case of reading with a resolution super fine of 16 line (dot) / mm in both vertical and horizontal directions. Therefore, horizontal 84
An A0 size original image of 0 mm and 1188 mm in length has a width of 13440 dots and a height of 19008 dots, which is the maximum size that can be processed: 4864 dots in width and 64000 in height.
It will exceed line in width.

In FIG. 2, the operator operates the display / operation unit 16
By operating, the information regarding the document size and resolution of the document to be transmitted is input (step 10).
0).

Next, the original set on the scanner is read with the input original size and resolution, and the input unit 2
It is sent out to the system bus 26 via 2 and stored in the memory 20 as image information (step 102).

Next, based on the inputted information on the document size and resolution, the long line length in the main scanning direction is made as large as possible within a range not exceeding the maximum processing capacity of the compression / expansion unit 14. Number of divided long originals and long 1
The number of line dots is calculated (step 104).

More specifically, the number of divided long originals is obtained by rounding up a value obtained by dividing the number of dots per line of the original by the maximum number of dots processed in the main scanning direction, and rounding up. For example, in the case of FIG. 3, the number of dots per line of the document is 13440 dots, and the maximum number of dots to be processed in the main scanning direction is 4864 dots.
3440/4864 = 2.7631. . . By rounding up to a small number, the number of divided long originals = 3 can be obtained.

Further, the number of long one-line dots can be obtained by dividing the number of one line dots of the original document by the number of divided long original documents obtained as described above. For example, in the case of FIG. 3, the number of long one-line dots = 13440/3 = 448
0 dot is obtained.

Next, the image information stored in the memory 20 is divided into a plurality of divided long originals so that the width in the main scanning direction is the number of long one-line dots calculated as described above. It is divided into measures (step 106). For example, as shown in FIG. 3 (C), an A0 size original is equally divided in the sub-scanning direction into three parts of length A, length B, and length C having a width of 4480 dots and a length of 280 mm. To be done.

When the image information is divided into a plurality of long lengths, these long length originals are respectively compressed by the compression / expansion unit 14, and the generated long length compression code data are connected in the sub-operation direction. An integrated long original compressed and stored in the memory 20 is constructed (step 108).
For example, the three lengths A, B, and C shown in FIG. 3C are compressed and sequentially connected on the memory as shown in FIG. 3D to form one integrated length original. . This integrated long original has a width of 4480 dots and a vertical length of 5702.
Since it is 4 lines, it can be transmitted according to the normal facsimile protocol within the maximum processing width and the number of lines in FIG. By dividing the document vertically as described above, it is possible to transmit even a large document size.

Even if the original size is the same, if the resolution is different, the division method is also different. In the example shown in FIG.
A0 size original same as Fig. 3, but 8 lines / mm in height and width
6720 dots in width and 95 in height read at the resolution of fine
The 04 line image (FIG. 4A) is handled. Therefore, in the example of FIG. 3, the image cannot be contained in the maximum processing width unless the image is divided into three parts.
As shown in (B), the length A and width B with a width of 3368 dots are 2
It will be good if it is divided. The long length A and the long length B are respectively compressed and connected in order on the memory as shown in FIG. 4C to form one integrated long original. This integrated long document also has a width of 3368 dots and a vertical length of 19008 li.
Since it is ne, it falls within the maximum processing width and the number of lines in FIG. 3 (B), and can be transmitted according to a normal facsimile protocol.

Next, the integrated long-length information divided and compressed as described above and the information necessary for dividing the integrated long-length information and synthesizing into the original image are transmitted or received. The flow of communication protocol control will be described below.

The processing flow of the transmitting side facsimile apparatus will be described with reference to FIG. When the operator operates the display / operation unit 16, the telephone number of the facsimile machine on the receiving side is input (step 120).

When the telephone number is input, the telephone number of the receiving side indicated by this telephone number is called (step 122), and the line with the other party is established through phase A as in the conventional case (not shown), NSF (Non-Standard Facilities), DIS
It waits for a (Digital Identification Signal) signal (step 124 negative determination).

When the NSF and DIS signals are received (Yes at step 124), the facsimile information field of the NSF frame (1) is searched to determine whether or not there is information indicating "there is the function 1 of this transmission / reception method". (Step 126). The function 1 of the transmission / reception method is a function of performing image information composition processing for reconstructing an integrated long document into original image information based on transmission document size information and resolution information as described later.

If the partner machine does not have the function of this transmission / reception system (No at step 126), the original image information cannot be reconstructed even if the integrated long information is transmitted to this partner machine, so the line is disconnected and the partner machine is disconnected. The communication with is ended (step 128).

When the partner machine has the function of this transmission / reception method (Yes at Step 126), "function 1 of this transmission / reception method"
NSS (Non-Standard facilities Set up) that includes information indicating "use", size of transmitted document, and resolution information
(1) Create a facsimile information field of a frame (step 130).

Next, the NSS (1) signal containing the above information is transmitted to the partner device (step 132).

Then, a TCF signal (Training Check) is transmitted to train the line (step 13
4), a CFR signal (Confir
It waits until it receives the "mation to Receive" (step 136 negative judgment).

When the CFR signal is received from the other party (step 136, affirmative judgment), the integrated long document formed on the memory 20 is transmitted (step 138).

When the transmission of the integrated long original is completed, an EOP signal (End of Procedures) for notifying the end of the integrated long original and the fact that there is no other document to be sent is transmitted (step 140), and this message is sent to the other device. MCF signal (Message Confirmation) indicating that the signal was completely received by
Is waited for (NO at step 142).

When the MCF signal is received (step 142)
Positive judgment), DC for instructing the other machine to disconnect the line
At the same time as transmitting the N signal (Disconnect), the terminal itself disconnects the line and terminates the communication (step 144).

In the example of the transmission processing shown in FIG. 5, only the size and resolution of the transmission original are transmitted as the division information necessary for the image information composition processing. However, in actuality, the image information combining process cannot be performed only with these pieces of division information, and as described later, the other device searches the division information table 30 to obtain other necessary division information. There is. In order to save this trouble, all the information necessary for the image information composition processing may be collectively transmitted to the partner machine. An example of the transmission process in such a case is shown in FIG. Note that in FIG. 6, the same steps as those in FIG.

In FIG. 6, when the NSF signal is received (Yes at step 124), it is determined whether or not there is information indicating "there is the function 2 of this transmission / reception system" in the NSF (2) frame (step 127). Note that this transmission / reception method function 2
Means a function of performing image information combining processing for reconstructing an integrated long original into original image information based on all necessary division information.

When the partner device does not have the function 2 of this transmission / reception method (No in step 127), the original image information cannot be reconstructed even if the integrated long information is transmitted to this partner device, so the line is disconnected and the partner device is disconnected. The communication with the machine is terminated (step 128).

When the partner machine has the function of this transmission / reception method (Yes at step 127), "Function 2 of this transmission / reception method"
NSS containing information indicating "use", transmission original size information, resolution information, number of long originals to be divided, number of 1-line dots of one long original, and position of line of long original to be divided (Non-Standard facilities Set
up) (2) The facsimile information field of the frame is created (step 131).

Next, the NSS (2) signal containing the above information is transmitted to the partner device (step 133).

Thereafter, the same transmission process as in FIG. 5 is performed to transmit the integrated long document to the partner machine. In this way, by transmitting all the information necessary for the image information synthesizing process to the partner device at once, the process of the partner device can be reduced. It should be noted that the NSF signal is searched to automatically identify which one of the "function 1 of this transmission / reception method" and "function 2 of this transmission / reception method" the other device has, and the transmission is performed based on this identification result. The division information to be used may be switched.

Next, the processing flow of the receiving side facsimile apparatus will be described with reference to FIG. The system waits until the call from the partner device arrives (No judgment at step 146), and when the call arrives (affirmative judgment at step 146), transmits an NSF signal including information indicating "there is a function of this transmission / reception method" to the partner device ( Step 148). The "function of the present transmission / reception method" indicates either "function 1 of the present transmission / reception method" or "function 2 of the present transmission / reception method" depending on the function of the facsimile device on the transmission / reception side.

Then, the process waits until the NSS signal is received (No at step 150), and when the NSS signal is received (Yes at step 150), the information indicating "there is a function of this transmission / reception system" in the facsimile information field of the NSS frame. It is determined whether there is any (step 152).
This NSS frame is also NSS (1) frame and NSS
(2) Indicates one of the frames.

When the partner machine does not have the function of this transmission / reception system (No at step 126), the partner machine does not have the ability to divide and compress a large document and transmit it. Therefore, the line is disconnected and the communication with the partner machine ends. (Step 154).

When the partner device has the function of this transmission / reception method (Yes at step 152), the NSS frame information is stored in a predetermined area of the memory 20 (step 156).

Next, when the TCF signal is received, a predetermined operation for line training is executed (step 15).
8) Then, after completion of the line training, a CFR signal for notifying reception preparation completion is transmitted (step 160).

When the compressed image of the integrated long original is received from the other device, it is stored in the memory 20 (step 162). This process is continued until the EOP signal is received (step 164 negative judgment).

When the EOP signal indicating the end of the transmission is received (NO at step 164), the MCF signal is transmitted to notify that the message has been completely received (step 166).

Next, when the DCN signal of the line disconnection command is received, the line is disconnected and the communication is terminated (step 16).
8).

FIG. 8 shows an example of the communication protocol procedure on the transmitting side and the receiving side as described above. According to FIG. 8, except for storing information related to “functions of this transmission / reception system” in NSS signals and NSF signals, which are optional signals, and transmitting / receiving, in the conventional communication protocol procedure, A2 or more not specified in the facsimile protocol It can be seen that the large size original can be sent and received. The facsimile apparatus according to the present embodiment may be provided with a digital line control unit for controlling a digital line, and communication may be performed using a communication protocol for the digital line.

Next, the flow of the image information synthesizing process for synthesizing the compressed image data of the integrated long original received as described above into the original of the original by the facsimile apparatus on the receiving side will be described with reference to the flowchart of FIG. explain.

In FIG. 9, N stored in the memory 20 is stored.
The size information and the resolution information of the transmission original are read from the SS (1) frame, the division information table 30 is searched, and the number of long sheets to be divided corresponding to the read information, the number of dots of one line of the long original, and the number of dots The division line to be divided is recognized (step 170). That is,
The facsimile apparatus that performs the processing of FIG. 9 has “function 1 of this transmission / reception method”. The contents of the division information table 30 are set, for example, as shown in Table 1 below.

[0065]

[Table 1]

When the present facsimile machine has the "function 2 of the present transmission / reception method", the long size to be divided from the NSS (2) frame stored in the memory 20 together with the size information and the resolution information of the transmission original. The number, the number of dots per line of the long original, and the division line to be divided are read and recognized (step 170). Therefore, in this case, the division information table 30 is not always necessary.

Next, the data for the number of long one-line dots is read from the storage area of the compressed image data of the integrated long original stored in the memory 20, and the compression / expansion unit 14 performs the expansion processing on this data. (Step 17
2). In addition, when reading the data for each long one line that undergoes this decompression processing, the first data is read from the beginning of the compressed image data, and thereafter, the compressed image data is sequentially read from the next address of the previously read data. read. For example, the compressed image data of the integrated long document stored in the memory 20 as shown in FIG.
Each line is sequentially read from the leading line of the long sheet A and is expanded.

Then, the decompressed data is sequentially stored from a predetermined address of the memory 20 (step 174).
That is, one long decompressed image is continuously formed on the memory 20 line by line.

When decompressing the compressed image data line by line, EOL which is a delimiter code added to the end of one line of these compressed image data is counted (step 176).

Then, the compressed image data is decompressed line by line and stored in the memory 20 until the counted EOL number reaches the division line number indicating the last line in one length (step 20). 178 negative determination).

When the number of EOLs reaches the division line number (Yes at step 178), one long decompression process has been completed. Therefore, this long decompression data is recognized as one long original, The predetermined address is changed to store the next long decompressed data (step 180).
The predetermined address does not necessarily have to be changed to the address of the next data of the decompressed data previously decompressed, and may be an address of a blank area on the memory 20 that can store one long decompressed data. .

Next, the number of elongated long originals is counted (step 182). If the counted number of long originals does not reach the number of long originals (No determination at step 184), the data is read from the line of the next long portion in the compressed image data of the integrated long original, and the extension processing is performed. Is executed (step 172) and the same processing is repeated (steps 174 to 182).

When the number of long originals reaches the number of long originals (step 184), the expansion process is terminated. By the above decompression process, decompressed data having a predetermined address as the start address is formed in the memory 20 for each of the long length A, the long length B, and the long length C, as shown in FIG.

Next, the process of printing out the decompressed data formed for each long original as one original will be described with reference to FIG.
Will be described below.

The data of the same line of the decompression data of each long original is read (step 190). The data of this same line is the line in the same order from the top line of each long document, the top line is read first, and the line next to the line just before being read is next. It is read sequentially.

Next, the same lines of each long original are combined,
One line of the printed document is created (step 192).

Then, the one-line data of the created print original is transferred to the buffer of the recording unit 18 (step 1
94). It should be noted that the transferred one-line data is connected in order on the buffer.

The above processing (steps 190 to 194) is repeated until the final line of the printed document is transferred (step 196 negative judgment).
