Description

[Detailed description of the invention] Technical field The present invention relates to an image processing device.

Conventionally, as the conventional image processing apparatus 1'g, a copying apparatus as a means for copying an original image, a facsimile apparatus as a means for transmitting an original image to a remote location, etc. have been widely used. When copying an original, the general copying apparatus currently in use can make a copy of an image with the same thickness and width as the original, or make an enlarged copy or a reduced copy.

Alternatively, if it is necessary to change the image intensity, the density can be changed uniformly over the entire copied image. However, with only such image processing functions,
There may be cases where it is not possible to fully meet the user's needs.

In contrast, the original image is converted into an electrical signal and read.
Image editing involves processing the image information converted into electrical signals to extract and duplicate a portion of the original, or compositing multiple images, or changing the image density of only a portion of the original. Copying devices have been proposed that have the following functions. However, as a copying apparatus is equipped with many such functions, the apparatus becomes more complicated, and the copying operation becomes cumbersome, resulting in a longer image processing time.

With facsimile, you can simply send an original image to a remote location using a telephone line, and if you need to make a copy along with sending the original, you can use an appropriate copying machine in addition to the facsimile machine. There are seven problems that require equipment. Furthermore, since facsimile machines do not have an editing function, if you want to send a document image after editing it, a human must edit the document image, which wastes effort and time. There are some problems. Furthermore, even when performing so-called short-distance communication, in which a document image is transmitted to other locations within a premises such as a factory or office, facsimile machines use telephone lines, which poses the problem of high costs.

Objective The objective of the present invention is to eliminate the above-mentioned problems and
An object of the present invention is to provide an image processing device that can perform image processing such as image editing, short-range communication and long-distance communication of image information easily, quickly, and inexpensively.

The address of the instruction code of the program stored in 80-8 is outputted to internal 80-5 via line Q'3 80-105. A signal line 80-103 extending from the I10 processor 80-1 to the path arbiter 80-2 and the path controller 80-3 is a signal line that transmits the status signal of the I10 processor 80-1 to both of them. Mat9, I10 processor 80-1
The signal lines 5o-1oa connecting the address/data/towing/sofa block 80-4 are signal lines for transmitting address information signals and data information signals, and the I10 processor 80-1 multiplies these signals. In plex mode, output to signal lines 80-104. That is, the I10 processor 80-1 time-divides the address information signal and the data information signal, and first outputs the address information signal and then outputs the data information signal to the address/data/<rafts block 80-4. .

The path arbiter 80-2 is a 1/1] processor 80-1.
According to the status signal supplied from the signal line 80-

and internal path 80-5, and receives and passes address information and data information between these buses.

Internal paths 80-5 of DMA controller 80 include a 16-bit address path with 64 kilobytes of address space and an 8-bit I data bus.

A clock generator 80-6 generates a clock signal of a predetermined wave number based on a reference oscillation output from an external crystal oscillator or the like to the I10 processor 8.80 through signal lines 110-120. '0-1. ．． bus arbiter 8

Transfer Acknowledgment (XACK) for MWTC and MRDC signals via 122
Upon receiving the signal, the multipath 30 determines whether or not the wait state is entered and whether the wait state is released, and based on the determination signal, the I10 processor 80- A path ready signal is output to 1.

The synchronization signal generation circuit 80-7 receives the above-mentioned I'ORC signal and INTA signal, and the address decoder e'o-1.
0 through the signal line 80-125, a signal for confirming the response of the ROM 8Q-8 is generated, and this signal is sent to the clock generator 80-8 through the side line 80-1213. By supplying the I10 processor 80-1 to the next operation, the I10 processor 80-1 can move on to the next operation.

ROM 80-8 stores a microprogram for I10 processor 80-1. Internal bus 80-5 to RoM
The signal line 80-130 leading to the sofs number is an address that transmits information indicating the address of the fetched instruction code when the I10 processor 80-1 fetches the microprogram stored in the ROM'80-8. It is a signal line, and ROM'8 (side line 0-48 leading to 1-8)
131 is a data signal line for the fetched instruction code.

The address decoder 80-10 selects the ROM 80 based on the chip selection signal of the I10 processor 80-1 supplied via the internal bus 80-5 and the signal line 80-135.
-'8 selection signal R via signal line 80-125
It is output to OM80-8 and synchronization signal generation circuit 80-7. From bus controller 80-3 to address decoder 8
Signal lines 80-113 extending from 0 to 10 transmit S2 signals, which are seven types of status information. That is, the S2 signal is a signal for identifying whether it is address information latched in the address/data buffer block 80-4, address information for the internal bus 80-5, or address information for the multipath 30. , and the address decoder 80-10 performs the identification.

Here, the operation of receiving and passing address information and data information between the DMA controller 80, the multipath 30, and the internal bus 80-5 will be described. First, a case where the multipath 30 receives and passes information will be described. I, 10 When outputting addresses and information to the processor 8o-1 or the address/data buffer 80-4, the bus controller 80-3 or the address/data buffer y8
When the ALE signal is supplied to 0-4, address/take buffer 80-4 latches address information into the address buffer. Further, when the path arbiter 80-2 acquires the right to use the multipath 30 after latching, the path arbiter 80-2 uses the address/data buffer □780-
The address/data buffer 80-4 outputs the latched address information to the multipath 30. Here, if the DMA controller 80 is in the write mode and the multipath 30 has been acquired, the I10 processor 80-1 outputs data information to the address/data buffer 80-4, and then outputs the data information to the address/data buffer 80-4. When the take buffer 80-4 receives DEN from the path controller 80-3, it outputs the data information to the multipath 30. On the other hand, when the DMA controller 80 is in the read mode, the take buffer 80-4 outputs the data information to the multipath 30. -4 reads data information on the multipath 30 and supplies the data information to the I10 processor 80-1.The I10 processor 80-1 reads the data information from the disk memory 80, which is the data transfer destination. This is done by confirming the XACK signal sent to 80-1.

Next, the operation of the address/data buffer 80-4 connected to the internal bus 80-5 is almost the same as described above, but in this case, when outputting address information to the internal bus 80-5, the path arbiter 80-4 -2 does not require an AEN signal. Further, whether or not to output data information to the internal bus 80-5 is determined by the bus controller 80-3 through the PDEN control.
Determined by the signal.

As the disk memory 90, for example, a Sword computer board [15-10] is used. The disk memory 90 has an internal disk controller circuit (not shown), and this circuit is connected to an internal path 80-5 of the DMA controller 80 via a data bus 80-141. Via side lines aO-142 and 80-143,
synchronous signal generation circuit 80-7 and I/'0, respectively.
It is connected to processor 80-1.

Data bus 80-. 140 transmits command information, result information, data information, and status information, and allocates an address to the former three pieces of information as a set of information, and the three pieces of information are sequentially transmitted to the disk controller circuit. They are distinguished by their output. Further, one address is individually assigned to the status information. Here, the command information is information that specifies the address and number of bytes on the disk memory 90, and the result information is information that specifies the address and number of bytes on the disk memory 90.
This information indicates the result of checking for errors when transferring information between.

The signal line 80-142 transmits a command busy (CBυSY) signal, and the synchronization signal generation circuit 80-7 identifies the above three pieces of information and status information. In addition, command information,
a set of information consisting of result information and data information;
Status information differs in the timing at which the data becomes ready, and each has a read mode and -)
The synchronization signal generation circuit 80-7 receives the xoRi:: signal transmitted via the signal line 80-1.12 and the CBIISY signal transmitted via the signal line 80-'142. Thus, four types of waiting times are created and given to the clock generator 80-6 from the line 80-'12B, and the above-mentioned two sets of information supplied to the I10 processor 80-1 are sent to the clock generator 80-6. 8
It is identified and captured at the clock timing from 0-6.

The signal lines 80-143 transmit a data read request (DREQ) signal indicating that the disk memory 80 is in a ready state, and an external termination (EXT) signal indicating completion of the MA transfer.

The flow of image information during DMA transfer will be explained step by step.

The storage area A) is 1!39584'O bytes, which cannot all be stored in the bank space of the buffer memory. The buffer memory space is then divided into three banks: bank 0. Divide into bank l and bank 2,
The bank is switched by the puncture switching signal outputted from the CPU circuit block 10 via the signal line 132 (see FIG. 4 and FIG. 6-2), and the specified bank is assigned to the memory map as shown in FIG. 8. . This division and allocation process will be described in the explanation of FIGS. 9-1 and 9-2.

The communication program space uses 8 kilobytes of the RAM (32 kilobytes 1-) 10-3 in the CPU circuit block 10. In addition, the work RAM space is 32 kilobytes of RAA in the CPU circuit block lO.

FIG. 8-1 shows an address map of the panf memory 22 in the buffer memory circuit block 20. This buff 7
The memory 22 is A4 size (29 mm x 210 mm)
)'s ability to store information that is divided into 16 pixels per 1lIII11 is annoying. League part 500 is A4
A size original is main scanned in the vertical direction (297 mm direction), and then the CCD 570. , 580 and 580 are 1ml
The pixels are divided into 16 pixels per 11 scans and 4752 bits of pixels are supplied to the image processing control unit 10'0. Also,
The league section 500 is used to hold the document in the width direction (210 mmO)
Since the CCDs 570, 58r) and 590 also scan in this direction by 16 lines per 1IIlffl, the document is scanned by 3380 lines in the width direction. Therefore, an A4 size document is decomposed into 151,386?20-bit pixels, and the image processing control unit 100 has 47 pixels.
52-bit pixels are supplied serially 3360 times.

The procedure for assigning an address to the image information supplied in this way and storing it in the buffer memory 22 will be explained. First, an A4 size document is divided into square unit blocks of 1 mm x 1 mm, which are composed of 82370 blocks.

One middle block has 18 lines with 16 bits.

In other words, if there is 256 bits of image information, 16 bits in the vertical direction is taken as one word, and one address is given to each word, one unit block consists of a group of pixels with 16 addresses. I don't like being treated like that. ]
The 4752-bit serial image information for 1 line, that is, the first line of the original to be scanned, is divided into pixel groups of 16 bits each corresponding to 1 mm in the vertical direction of the original and sent to the image processing control unit 100. The first 18-bit pixel group that is supplied and transferred is 00OO of the buffer memory 22.
OH address, the pixel group on the next 16 bits is 0001f))1
address, and similarly, pixel groups of 18 bits each are successively 1B
(IOH) Address 2, oo, 0208 address, 000
Address 308..., 01280) will be stored as address 1.

The addressing of each line to the buffer memory 22 is determined by the CPU circuit processor 10 using the address counter 21-
This is done by setting the initial value to 6. Also, when outputting the image information from the buffer anomaly 22 to the printer section 600, it is read out every 16 addresses starting from the initially set address, similarly to when storing the image information.

Next, the 4752-bit image information for the second line is processed from address 0OOOIH to 01 in the same way as for the first line.
．． It is stored up to address 281H. In this way, the first
Line 1536 (98mm in the width direction) from the line to the 1538th line from address 0000'OH to 8F5FF
This address space is stored in buffer memory 2.
Set it to bank 0 above 2.

Next, 1 from the 1537th line to the 3072nd line
536 lines are stored in the same way as bank 0 from 70000H to 1]j5FFH4, and this address space is designated as bank 1 on the buffer memory 22. Zarani No. 30
288 lines from the 73rd line to the 3360th line are stored in EOQO, (from address IH8 to address F4EIF) 1, and this address space is designated as puncture 2 on the header memory 22.

As shown below, if you use the method of asking one address for one word of image information and storing it, a 1 mm x 1 mm square will be used as a unit block, and A4 size data will be stored at consecutive addresses in the Panzer memory 22''. This means that the entire area of the original can be stored. This allows the operator to use the console unit 200
If you specify the image processing area in mm1i using can be transferred at high speed without going through the CPU circuit block IO.

In other words, by specifying a set of the first address and the last address, the image information of 1B main scanning line (In+n+width) is transferred by DMA, which reduces the need for address settings during DMA transfer and increases the speed of transfer. can be achieved.

Furthermore, storing image information in this manner is more effective when extracting image information for editing, since the addresses are continuous from the right side to the left side of the image to be extracted. For example, when extracting image information with a length of 20 mm in the vertical direction, the address setting by the CPυ circuit block 10 is 2.
This will result in 0 times.

Further, since the address corresponds to the position on the original image in units of mm, when editing the image, the operator can simply specify the position on the original in units of mm, which is convenient. In this example, since CCDs 570, 5808, and 580 having a reading capacity of 18 bits per 1m+n were used, the 16 bits in the vertical direction were made to correspond to the air address, but since the bits corresponding to the air address , that CC
D570. ．． It goes without saying that other values may be used depending on the capabilities of 580 and 580, and that the same effect can be obtained even if the address is set in units other than mm, for example, units of inches.

Although the multi/head address bus 30 has a bit address bus, the area that can be accessed by this multi/head 30 is 1 megabyte. In other words, 106 pieces of 8-bit data can be accessed, and when accessing 16-bit data, it will span 2 addresses, so in this case, the 8th-bit data will be accessed.
As shown in FIG. 2, consecutive addresses are assigned to every other 16-bit data address, so that 18-bit data is input/output only when an even address is accessed.

(3,,5) Disk Memory No. 1 O-11N (A) The physical address structure of the disk memory 80 is shown. Reference numeral 91 denotes a drive, which is numbered ○, l, . . . corresponding to the number of disk devices. In this embodiment, only one disk drive 6 is used, that is, only the drive with number 0 is used.Drive 81
has three heads 92, each head 82 takes charge of 354 tracks 93, each track 83 consists of 1a sectors 84, and each sector 84 can store data of st2/<ite. Therefore, the storage capacity of disk memory 90 is approximately lθ megabytes.

In the disk memory 80 having such a configuration, the first
Addresses on the Dinuk memory 80 are changed according to a fixed sequence as shown in Figure 0-1 (B), and data is accessed continuously. As shown in this figure, sequence number SN, head number HN, and track number TN
There is a relationship determined by the following equation (1).

5N=3X TN+ nN (however, HN=O~24s
-o~353) (1) That is, when a certain sequence number S'N is determined, the track number TN and head number HN are determined correspondingly, and the addresses of the head 82 and track 83 to be accessed next are Sequence number SN+ which is the determined sequence number SN plus 1
These are the head number and track number obtained corresponding to 1. Sectors 84 in track 93 are accessed in ascending order of sector number 5cTN.

Fig. to-2' shows an index table provided in a predetermined area in the disk memory 90, and the use status of the disk memory 80 is managed by this index table. In this embodiment, among the sectors 94 with head number HNjO and track number TN=0, sectors with sector numbers 5CTN=0 to 13 are used as index table areas, and in particular, sectors with sector numbers 5CTN = 0 to 8 sectors to disk memory 90
The sector number 5CTN is assigned to the Seftabi Ntoma Eve table 84A which shows the usage status of each sector above.
= Sectors 9 to 13 are allocated to the file index table for file management. Sector number SCT, 'N=
Sectors 0 to 13 are loaded mtJ into the fixed area 8000H to 78FFH of RAM 10-3 by a program (oven program) that reads the index table into RAM 10-3 in the CPU circuit block 10, and undergo predetermined operations. Then, the fixed areas of RA old 0-3 are written to the disk memory 80 as old by a program (close program) that stores them in the disk memory 80.

The sector bitmap table is shown in Figure 1O-3.
Divide area 1]4A into two 4-byte blocks each from 5N=0 to SN=1081 in descending order of sequence number SN, and each block uses 1 track, that is, 18 sectors. Data indicating the status is stored by allocating one bit per sector.

As data indicating the usage status of a sector, for example, if a certain sector is in use, '1°' is stored in the safebint corresponding to that sector, and if it is unused, '0' is stored.

When registering a new data file in the disk memory 80, find an area where the number of consecutive sectors required for registration are empty, obtain the sequence number SN and sector number 5CTN corresponding to that area, and then Store l" in the sector bit corresponding to the sector. Conversely, when erasing a data file, store "o" in the sector pinto indicating the corresponding area. However, the bit corresponding to the index table, that is, block 1411+ is stored in advance in 0, and writing to this 2.ri0 is prohibited to prevent data files from being erroneously registered in the index table.

File index table is Nodisk memory 3
0, namely, image data files (image files), application files, and control programs for the tree system. Assuming that the image file is file type O and the application file is file type 2, the management status of these files using the file index table is shown in Section 10.
- Shown in Figure 4.

The file index block FITI consists of four blocks of 2 bytes each: status A, MAX block, 1 block size, and current B number, and is deleted when the disk memory 80 is initialized.
Stores the usage status of the entire file index table. Status A is an area used for system expansion, and is left unused in this embodiment. The MAX block stores data for the total number of files that can be registered in the disk memory 80, and in this embodiment, the total number is 50 (3).
2H). One block size indicates the length of the index of various data related to the file per file17, and in this embodiment, the length of - is 38 (26H) bytes as described below. The current B number is
The number of files registered in the disk memory 90 is stored, and when a new file is registered, it is compared with the number stored in the MAX size, and if the number does not exceed that number, it is incremented by 1. New registration is done, and MAX
If the size exceeds the number, no new registrations will be taken advantage of. Conversely, if you want to delete one file that has already been registered, use Karen l, 8
The number stored in the number is decremented by 1 and the file is deleted from the disk memory 80.

FIT2 and FIT3 indicate file index blocks for file type 0 and file type 2, respectively, and each stores 38 bytes of data. In FiT2 and Fl, T3,'
RSV is a 2-byte area used for system expansion, and is unused in this embodiment. File No. is a 2/'-ite area for identifying the file number when the operator arbitrarily assigns a number from 1 to 89 to a file and registers it in the disk memory 80. The file type is a 2-byte area in which data of a double file type "0'' or "2'° is written. Puncture and address in FIT3 are determined by CPU circuit block 10.
: indicates the puncture and address of RAM 10-3 in , and is a 2-byte and 4-byte area, respectively, used when allocating an application file to RAM 10-3. This is a 6-byte area that stores the byte count length.

The sector count is a 2-byte area that stores the number of sectors used for the registered file.

The sequence number, drive number, head number, track number and sector number are as follows for the registered file.
Sequence number and drive number at the beginning of the storage area.

This is a 2-byte area each for storing the head number, track number, and sector number. XO, Y in FIT2

The method of MH encoding and MR encoding of image information using this system and transmitting it to other systems is CCIT
According to Recommendation 7.4 of T.T., the following points should be considered when applying Recommendation 7.4 to the present invention.

(1) In the device of the present invention, the vertical direction of an A4 size document.

(in the direction of 287 mm) is one line, and the resolution is 16 bits/ml11, so what is the maximum run length, i.e. when the l lines are all white or all black? The length is 4752, which exceeds the maximum expression range of 2823 (=25[10+E13)] of the extended letter MH code.

(2) In the device of the present invention, the parameter K is set to infinity.
Transmission is performed using the dimensional encoding power formula. That is, for an A4 size document, the first line that is first transferred to the DDX interface 60 is MH encoded, and then the remaining 3358 lines are MR encoded.

Regarding point (1), the reason why the length direction is set as one line is as follows. In other words, (i) reducing the number of transmission lines to reduce the transmission time; and (
2) By reducing the overall movement distance of the sensor in the sub-scanning direction in the league part 500, the league part 500 is made smaller.

Regarding point (2), the reason why the parameter K is set to infinity is to save the time of repeating MH encoding each time by setting the parameter K to a small finite value. The basis for setting this is that the image information to be transmitted has already been binarized by the CG driver 50 and stored in the buffer memory 22, and the parameter K is set to a small number 41 ((j is the reading error This is because the meaning of making it smaller is lost.

The process of transmitting image information from this system to another system via the DDX line 800 will be described.

First, from the buffer memory 22 to the signal line 13? The image information for 1 life ('4752 bits) transferred via the line buffer 80- is transferred via the data/clock interface 60-1 and the write switch 60-3.
4.Supplied to 80-5 or 80-B. This image information is transferred to a line buffer 60-4, 60-5 or 60-4 at a transfer rate of 1 bit per 0.1 microseconds (p's) in synchronization with a 10 megahertz (MHz') clock (S). In other words, the transfer time of one line of image information is 475.2gg. -4, and when the line buffer 60-4 finishes storing the image information of the first line, the J converter 60-7 transfers the image information to the line buffer 0-4.
Open the gate of Line Pack Aro 0-5 and 60-
6 is closed, the stored image information is fed into the RL counter 60-8, and the white and black run lengths for that information are counted and roughly run length encoded for that first line. Image information is RLHMH/M
It is converted into an MH code by an R converter 60'-10. While the line buffer 60'-4 is outputting image information, the switch 60-3 switches between the line buffers 60-4 and 60'-4.
-6 is closed, the gate to line buffer 60-5 is opened, and the image information of the second line is transferred to line buffer 60-5.
Supply to 0-5. All image information on the first line is M)
If the image information of the second line is encoded, the switch 80-7 supplies the image information to the RL forward/reverse counter 60-7, the relative pixel change position from the first line is counted, and the RLMM ) MR encoding is performed by the I/MR converter 80-10. The image information of the third line transferred to the line buffer 60-6 is also processed in the same way as the second line. 60
The image information output from -6 is the RL forward/reverse counter 6.
0-7, and is supplied to an RLM MH/MR converter 80-10, where it is MR encoded.

Next, the run-length encoded image information supplied to the RL→MH/MR converter 80-10 is compressed by M)l encoding or MR'i:f encoding.

As mentioned above, in the device of the present invention, the maximum run length is 4752, which exceeds the maximum expression range of 2623 for the extended M)I code.
Expand the code further.

(1) Normal M when run length RL<256'O)
Represented by I symbol. That is, when RL<84, it is represented by one terminating code.

64≦R'L<,! 580 is represented by one make-up code and one terminating code.

(2) When run length RL≧25GO, the make-up code “0000000 till” of 2560 is regarded as a special code and handled as in the following (a) and (b).

(a) 25130≦R1,≦2623 = 25so
+ In the case of e3, as in case (1), one make-up code (in this case, the make-up code of 25H)
and one couminating code.

(b) 2560 when 21323'<RL≦4752
Following the make-up code, one more make-up code is added as required, and then one terminating code is added. That is, in case (2), there is a case (a') in which the make-up code of 2560 is immediately followed by a terminating code of the same color, and a make-up code of 2560 is followed by a make-up code of the same color, and then is followed by a terminating code (b
). An example of processing in case (2) is shown below. The underlined numbers are the added makeup codes.

Explain the meaning of the numbers.

12-2 IN is each signal, its name, image processing unit 10
6 is a diagram showing a lower number (arrow) between the DDX interface 60 and the DDX interface 60; FIG. Here, FC and 5Gft
, are the safety ground wire and the signal ground wire, respectively.

The image processing unit 10 receives the call request signal ((RQP) using DDX
This is a signal requesting the interface BO to connect (make a call) with another system, and this signal C±Connection status (I)
When CND) is energized, the number is deenergized at the same time, and the non-connectable No. 4M (NRYD) is energized, and when l,% and t±
Treated as invalid. Call signal (CIP) 4i”
This is a signal from the DDX interface 80 to the image processing unit IO indicating that a call has arrived from another system, and the processing for CND and NRYD is similar to CRQP.

The dialed number signal (DLN) is activated simultaneously with the activation of CRQP and transfers the 7-digit station number of another system. .

The connection request signal (CN, Q) is a signal that the image processing unit IO requests the DDX interface 60 to connect to the DDX line, and is activated at the same time as either CRQP or CIP is activated, and NRYD It is disabled when energized. Also, while it is necessary to seize the line, C
NQ is energized, and de-energizing CNQ disconnects the line.

The non-receivable signal (NRYP) is activated when the image processing unit 10 cannot be in a state where it can transmit or receive within 6 seconds. NXRY D indicates that the line cannot be connected when the D'DX line 800 is busy or the not ready switch of the NCU 302 is activated. This NRYD line is always energized or deenergized depending on whether line connection is disabled or enabled, respectively. Furthermore, if the CHD is not activated even after a certain period of time has passed after CRQP is activated, the image processing unit IO determines that connection is not possible.

When CND activates RQP or CIP and activates GNQ, the system and the other system with which it communicates (other station)
It is activated when the communication conditions of and are satisfied, indicating that the line connection has been completed and the system is ready for communication. CND is de-energized when CNQ is de-energized or when the other station disconnects the line. Sendai 4 呵 and other issues (RD
S) and ready-to-receive signal (RDR) indicate that the image processing unit IO can be in a state where it can transmit and receive image information for one A4 size document within 6 seconds, respectively, and the CNQ Simultaneously with energization, RDS or RDR is energized.

Transmission mode signal 1+ (f4Ds) and reception mode signal (
MRR) respectively send image information from this system1.
) and receive mode, and these modes are determined by looking at the RDS and RDR of both the calling and called parties. Immediately after sending or receiving,
Each can also receive or transmit.

The Ready to Transfer signal (RDT) is activated within 6 seconds after the MDS or MDR is activated, indicating that image information can be transferred in transmit or receive mode.

The transmission data request signal (RQS) is energized and deenergized at regular intervals, and the DDX interface 60 requests the image processing section 10 to transfer one line of image information. When the RQS is detected, the image processing unit 10 activates the transmission data valid signal (SVA) and sends one line of image information (
SDT) is transferred. RQS is de-energized upon completion of its transfer. The RQS repetition period is set longer than the minimum transmission time. SVA is activated according to RQS, indicating permission to send SDT (sampling in synchronization with i clock (SCK)), and deactivated when SDT transfer is completed. RVA is activated at regular intervals. The DDx interface 60 receives from another system, requests to receive one line of decompressed image information (,, RDT), and allows the ROT to be sampled in synchronization with the reception clock ('RCK). The repetition period of RVA is the same as that of RQS.

SDT and RDT represent binary transmitted and received image information in black and white, SfJ and RCK, respectively.
are the sampling clocks of SDT and RDT, respectively.

In the device of the present invention, when transmitting between this system and another system on the DDX line 800, the transmission direction is the calling system (calling station) and the called system (calling station). Both stations (called station) compare the RDS and RDFI and decide as shown in Figure 12-3, thereby preventing errors in the transmission direction.

That is, in FIG. 12-3, the energized state is indicated by an arrow indicating the O1 transmission direction, and the deenergized state and the transmission disabled state are indicated by x. When R[]S is activated, and when only RDR and RDS on the calling side and RDS on the called side are activated, the transmission direction is from the called side to the calling side. shall be taken as a thing. Also, when only the RIIS on the calling side and at least RDR on the called side are activated, and when the RDS and RDR on the calling side and at least R[], R on the called side are activated,
11, the direction of transmission is from the calling side to the called side. Transmission is disabled with combinations of RDS and RDR of both the calling and called stations other than those described above.

FIG. 12-4 shows an example of a procedure for transmitting data between a calling station and a called station. Here, ID
S is a transmission capability identification signal, which identifies the transmission capabilities of the calling and called stations, i.e., RDS and R
This is a signal that mutually informs each other of DR. For example, the transmission format is “0000 RDS RDR1
The 8 bits of 0'' are sent sequentially from the most significant bit to the least significant bit, and both stations are connected to the R of this system.
From the DS and RDR and the RDS and RDR of the other station, the transmission direction is determined as shown in Figure 12-3.

RDY is a transmission ready signal, and its transmission format is, for example, "00010010°."

is transmitted in the same manner as in the case of IDS, indicating that preparations for transmitting and receiving image information for one document in the transmission direction determined by IDS communication are completed.

MHI is MH encoded first line image information, MR
2 to MRn+1 (1≦n≦3360) is MR encoded image information of the 2nd to ni1 lines, and Hn is M)l
Encoded image information of the nth line and MRn+
1 to MR338Q are MR=encoded nth 1 to 3rd
360 lines of image information, MHI to MR3380
shows the image information for one A4 size document.

RTQ is a retransmission request signal, and if there is an error in the received l-line image information, that is, when the called station demodulates the transferred image information, the length of one line becomes 0 or 4752 bits. If not,
This information is not taken into the buffer memory 22 of the called station, and the called stage manager issues a retransmission request to the calling station.

RTC is a transmission end signal, and the calling side stage code is C.
Line termination code EO in Recommendation T,4 by CITT
A signal obtained by adding 1 to L is transmitted to indicate completion of transmission of image information for one image.

DCN is a line disconnection signal, and its transmission format is, for example, "01000010", which is sent out in the same manner as IDS to mutually notify each other of line disconnection.

Immediately after the line is connected, the calling and called stations begin sending IDSs to each other, and repeat this process at least three times until their stations are ready for the transmission mode. Here, for example, at time A, if the transmission direction cannot be determined, it is determined that transmission is impossible (see Figure 12-3), and both stations send DCN to each other and disconnect the line. When their own station is ready, both stations send RDY at least three times until both stations are ready, and when both stations are ready and RDY is sent from both stations, that is, at time B.
In , the called station enters a receiving state without sending control signals toward the calling station, and the calling station enters a transmitting state.

When transmitting image information for one A4 wallet document, for example, if a transmission error occurs in the image information of the nth line at time E, the called station will send an RTQ to all calling stations. In response to this, the calling station performs MH encoding on the image information of the n-th line, sequentially encodes the image information from the p n+l line to the 3360th line, and transmits the MRi-encoded data.

When the transmission of the image information is completed in this way, the calling station 11 sends an RTC to the called station, and then both stations send IDS to each other, and at this time, the transmission conditions are set as shown in Figure 12-3. If the above is satisfied, other image information is subsequently transmitted and received from time point C. On the other hand, if that condition is not met, a DCN is sent to the phase tour and the line is disconnected.

(6) Image editing method Image editing is performed by appropriately performing DMA transfer between the buffer memory 22 and the disk memory 90. That is,
League, A4 size manuscript 1 read with fII500
Image information for one sheet is stored at a predetermined address in the backup memory 20, and a part of the image information is stored in the disk memory 80 via the DMA controller 80. Therefore, the buffer memory 22 is erased, the image information previously stored in the disk memory 30 is restored to the desired address space of the backup memory 22, and the image data is transferred to the printer unit 60.
By copying at 0, it is possible to obtain a copy with unnecessary parts of the document trimmed.

Image editing such as changing the image position and cropping is performed according to an image processing program created based on commands (described later) input from the command menu section 220 shown in Figure 3-2. Such an image processing program is
The image processing program that can be stored in the disk memory 80 and stored therein is defined as an application file. Further, image information stored in the disk memory 80 is defined as an image file. When registering these files in the disk memory 80, as described above, the file is asked for a two-digit file number as a file name, and an instruction is given as to whether or not the file can be deleted. do.

(6,':3) Editing procedure 191, 20th interval, 21st figure and 22-1 to 22-2
A procedure for editing image information using the editing station 400 will be described using FIG. 2-b.

When the editing station 400 starts up, first step S is performed.
At step L, the display division of the CRT 300 screen and initialization of system constants are performed. C; RT300 is 40 horizontal characters,
It has a screen 301 that can display 24 vertical lines. No. 22
Figure-1 shows an example of display division of the screen 301, where:
A working area 310 from the first line to the 19th line is used to display characters transferred from the image processing unit IO to the editing station 400. 20th shot 3
20 is a blank area, and no display is made in this area, making the boundaries between the working area 310 and the following areas clear to the operator. 330 of the 21st shot is the mode display area, and the h6 collection station 4
Displays which mode (described later) 00 is used.

The 22nd stroke 340 is a message area where the editing station system wholesaler 450 displays to the operator commands and parameters to be input next, error codes, etc.

The 23rd stroke 350 is a user input button, which monitors characters such as file numbers input by the operator.

The 24th stroke 360 is a status display area, which is an area for displaying the status of the image processing unit 1O to notify the operator.

As other initialization, when a command is input, the command echoed back from the image processing unit 10 is displayed in the working area 310, the carry return code is recognized, and the command is sent back from the image processing unit 10. The next command is displayed from the left end of the next line, and if the command is displayed from the 1st line to the 18th line, the working area 310 is scrolled up by one line, and the command is always displayed in the working area 310. so that it can be accommodated in

When the editing station 400 is not online with the image processing control unit 100, the screen 301 in FIG. 22-1 is displayed.
For example, if all 1 color and message area 3
40, the operator's online request, i.e., “REQU
EST "as a message to accept the key" NOT
"READY, ENTER REQUEST KEY" is displayed, and in step S2 it waits for the human input of the "REQ! JEST" key.

Box 1 Stage Adventure 400 can be roughly divided into two modes:
That is, it operates in echo mode and edit mode. In the echo mode, the character image input by the operator via the console section 200 is directly transferred to the image processing section 10, and is also transferred from the image processing section 10 to the editing station 40.
The characters transferred to CRT3 (10
This is the mode that is displayed on the screen.

Edit mode creates application files,
This is a mode in which correction and execution commands are given to the image processing unit 10. In this mode, the character manually created by the operator is
First, c7 in the editing station control section 450) RAM4
The 5G data is temporarily stored and is transferred to the image processing unit 10 after being arbitrarily modified by the operator on the CRT 3.00. Also,
In the editor) mode, the editing station control unit 450 receives data from the disk memory 90 via the image processing unit 10.
In particular, the period for receiving the absorption file transferred to the command mode is set as the command mode.

FIG. 21 shows the operation of the editing station control section 450 when there is key human power in each mode. First, the mode is determined in step SA, and if the echo mode is determined as a result, the process proceeds to step SB, where the echo-packed character from the image processing unit 10 is displayed in the working area 31.0, and step SG Move to
The routine returns to the normal routine shown in FIG. If it is determined that it is the edit mode, the process proceeds to step SC, and since the working area 310 is being used by the screen editor in this mode, the character is displayed on the user's canilia 350, and the process proceeds to step SG. Also, if it is determined that the mode is command mode, proceed to step SD,
It is determined whether the reception of the application cage 3 file is completed. Here, if it is determined to be a fixed decision, the process moves to step sF, sets the occupancy completion flag of the application file, and moves to step SG. On the other hand, if the determination is negative, the process proceeds to step SE, where the transferred characters are sequentially stored in the RAM 45G, and the process proceeds to step SG.

By instructing the "R11QUEST" key, the process advances to step 7'S3, the editing station 400 is set to the echo mode, and in step S4, an image editing program startup request signal is output to the image processing section 10. next,
In step S5, activation of the image editing program is confirmed, and if the evaluation is determined, the process moves to step S4, and if the judgment is affirmative, the process moves to step S8. In step S6,
For example, the screen of the CRT 30 (l) should be entirely black, and the message area 340 should be marked with "0N-LINE" in green text.
” is displayed to inform the operator that the request to start the editing program has been validated, and the mode display area 33
0, displays "ECHOMODE" to inform that the editing station 400 operates in echo mode;
Step S? Waiting for command personnel.

In step S8, the input of the command key input from the console unit 200 is determined, and according to the determination result, step S10. S15. S20. , proceed to S25 or S30.

In the echo mode, since the screen editing function of the CRT 300 does not exist, if there is an input to the key group 228 related to screen/lean editing, it is processed as an invalid input in step SIO, and the input is processed as an invalid input in step S7.
and waits for the next 4 inputs. Further, the same processing is performed when keys for ending the edit mode, that is, the -build reset key and the edit end key are input.

If the command character in the key group 222 has the human power, the process advances to step S1B via step S15;
The input command is transferred to the image processing unit 10, and the system operates according to the command. For example, as shown in FIG. 23-2, when the RE" key is input, the characters "RE" are displayed on the screen 301, and by instructing the carry/return key 225, the league drive signal is switched to the league section. 500 to read the original f/4 image.

Coordinate input request keys 227, ie, 117, 1. When the position designation key and the region designation key are pressed, the process advances to step S20, where it becomes possible to designate a desired point on the document placement section 240 with the stylus pen 280.

When editing an image by specifying the area to be edited), when you press the ``Specify area'' key, a message such as ``ENTERTOP RIGHTPOSITI'' appears in the message area 340.
"ON" is displayed, and the left half of the working area 310 is displayed in white to prompt the operator to point A (see Figure 1O-5). Edit area.

315 is displayed.

When the operator indicates point A, a coordinate display line 312 is drawn, for example, in green, on the image editing area 311 in the vertical and lateral force directions of point A' corresponding to point A, as shown in Figure 22-3. In addition, the X and Y coordinates of point A, that is, x0 and YO, are displayed in mm on the user input canister 350. Next, in message area 33'O, "ENTE" is displayed.
"RBOTTOM LEFT POSITION" is displayed to prompt the operator to manually move point B. When point B is input, in step S2+, the vertical and horizontal lengths of the edited image are calculated from the coordinates of point B and the coordinates of point A. ×1 and Yl are calculated, and then in step S22, the manually specified editing area at point A and point B is placed in the corresponding area 313 on the image editing area 311, as shown in Figure 22-4. for example,
Display in red. At the same time, message area 330 is OK! AREA l5RECOGN IZED
''' is displayed to notify the operator that the editing area specification is complete, and the user input canister 350 displays XO, YO,
i and Yl are expressed as numerical values in units of n+m. Next, the process moves to step 518, and these numerical values are sent to the image processing unit 10.
Transfer to.

In addition, when specifying the position and performing the image & i collection, specify the °°position specification'' key.In this case, specify only one point, that is, specify only point A in the case of area specification.

When that point is input, 1 For example, the coordinate display line 31 is displayed in red.
2, and user Canilia 350 has XO and Y
Display O in units of Iam. When the editing station 400 recognizes the specified position 1ξ in this way, the message area,
OK to A330 i POSITIONIS REC
:0GNIZED'' is displayed to inform the operator that the coordinates have been validly input, and the image processing unit
The gauze value information of xO and YO is transferred to.

When the area specification or position specification is completed, the process returns to step S7, and the editing station 400 again uses the console unit 200.
Wait for the human power from , and then by the human power of the new command, the command and the specified coordinates that were displayed before executing the area specification or position specification are displayed on the working area 310 as shown in Figure 22-2. . In addition, if the operator instructs another command key after instructing the °゛area designation゛ key or °゛position designation °“ key and before inputting coordinates, the area designation or position can be specified. The state of waiting for input of a specified outer frame is canceled, and the command that was displayed before the instruction of the °°area designation' key or the °°position designation'° key is displayed in the working area 310.

To release the editing station 400 from the control of the image processing unit IO and cancel the online state, manually enter the KL command using the alphabet key i'l-223. At this time, step 5213 is passed through step S25.
Step S27 outputs the character information "KL" to the image processing section 10 to request termination of the image editing angle program. This step S2? When the editing station control section 450 detects that the editing program of the image processing section 1O has not been completed, a negative determination is made, the end input is invalidated, and the process moves to step S7. Further, if an affirmative determination is made in step S27, the online state is canceled and the process moves to step S1.

Inputting a group of keys 228 related to application files;
In other words, when there is an instruction using the “°routine work” key, the °°application file call key, and the °“application file creation key”, the second
As shown in FIG. 1, in step S30, the editing station 4
00 is set to edit mode.

Here, ``Create application software''.

The "°°Application File Recall" key is a key used to instruct when creating a new application file, and the "°°Application File Recall" key is a key used to instruct when calling and modifying an application file registered in the disk memory 8o. The ``Standard Work'' key is a key used to call up the application file and instruct the image processing unit 10 to sequentially transfer its command strings to the image processing unit 10 for image editing.

When these keys are input, input determination is made in step S31 for each case of routine work, calling an application file, and creating an application file. In edit mode, to handle application files.

Specifying the file number is essential. Therefore, in the case of
``The color is blue and the message area 340'' is ENT.

The file number FN of the image file is displayed in the upper right corner of the area. On the right side of the screen, for example, this is colored blue, and within that plane there is an area 316 determined from the changed coordinate position information XO' and YO', x1 and Yl.
B and 317B are displayed in green. Further, a rightward arrow 318 is displayed in the center of the screen to indicate movement of the image.

When the image file movement display is completed, the message area 340 displays 'END OF TRACE'.
"MODE" is displayed to inform the operator that the trace has ended.
When you point at any point, a list of commands for the application file you are creating will be displayed.

In other words, it is possible to visually understand where the image information is moved by the application file that is currently being traced.

When creating an application file, as mentioned above, image file number 1 image area ('XO,
YO, Xl, Yl), Edited image change position (XO'
, YO') and the number of copies to be printed, or by creating a program using them as variables, it is possible to add flexibility to image editing.

For example, the following command WT can be configured as an application file that performs trimming using variables.

(1) RE (CR) Read the original by the reader unit 500 and store it in the filer memory 22 (2) XO,
'10. Xi, Yl) + 17) Il - Shift y Ilwo storage space between 2 and 2 (3) 5TCN, O) (C:'R) Register the image file of (2) in the disk memory 80 as file number N (4) LO(N, (i) (CR) File number N

(S) (CR) Duplicate S images of image information stored in the panzer memory 22.

Create a John file.

In this way, when the operator creates an application program and the creation is completed, the operator inputs the editing end key in step S34. At this time, the process advances to step S35, and the editing station control unit 450 displays "5TORE THIS COMM" in the message area 340.
AND FILE? ” is displayed to confirm whether or not to register the application program stored in the RAM 4.58 in the disk memory 90 as a file.

When the operator negates this message and inputs the "'N passkey", a negative determination is made in step 53B, and the editing station 450 exits the edit mode and enters the l!
I11 side 301 all 301 is step S3? and return to echo mode.

On the other hand, when the operator requests file registration by manually pressing the ゛°Y゛゛° key, a fixed determination is made in step S36, and the process advances to step S38, where the operator previously specified 1j in step S32. Based on the obtained file number, a R1 STEEN (...) command is sent to the image processing unit IO to obtain permission to transfer the application file. If a file with the same file number as that file number is not registered in the disk memory 90, a negative determination is made in step 83.9 and the process proceeds to step S40, where the image processing unit IO is transferred to the &i collection station control unit 450. The file registration is permitted and the file transfer is executed.

When file 0 recording ends, step S3? Shifts to L and returns to echo mode. A signal indicating that a file having the same file number as the created file has already been registered is transferred from the image processing unit IO to the editing station control unit 450.

If so, a determination is made in step S39 that t'r is certain, and the process proceeds to step S41, where a message such as "FILE ALREADY REGIST" is displayed in the message area 340.
ERED.

DELETE OLD? ''' is displayed and the operator is asked whether to delete the file with the corresponding file number in the disk memory 90.

If the operator affirms, proceed to Step 7'S42,
The editing station control unit 450 sends a DE(...) command to the image processing unit IO, and then in step S3
Return to 8. If the operator denies it, the process advances to step S43, and the editing station control unit 450 displays 'ENTERFIUENO,ANDCAR' in the message area 340.
RIAGERETU'RN'' to prompt the operator to input a new file number. When the operator manually enters a new file number, the process moves to step S3B.

Note that if the response of the image processing unit 10 to the ED command is other than the error code °'08'', the editing station control unit 410 determines that it is impossible to transfer the application file, erases the screen 301, and shifts to echo mode. At the same time, in the message area 340, the error codes listed in Table 7 are added.

Next, processing LIIll-1 when there is an instruction of the application file call key will be described. Step S3
When the file number is entered manually in step 2, the JilI collection station 400 is set to command mode, and 11
The 1M collection station control unit 450 issues the xR(...) command to the image processing unit 10 according to the input file number.
Output to. Therefore, in step 5413, the image processing unit IO calls the corresponding application file from the task memory 80 and transfers it to the RAM 458. When the editing station control unit 450 completes receiving the application file 41-, it moves to the edit mode S33 in step S47, erases and inserts lines and characters, etc., using the same procedure as for creating the application file, and creates the application. /) ---Repair the John file. In addition, if an error code is sent from the image processing unit IO,
The editing station control unit 450 erases the screen of the CRT 300 and returns to the echo mode, and also displays an error code, an error message corresponding to the error code, and a status in the message area 340, status table, and J\area 360, respectively. and is displayed.

Next, the procedure for routine business input processing will be described. The operator is
When the standard job key is pressed 1 and the file number of the desired application file is input, the editing station control unit 450 stores the specified file in the RAM 45, as in the case of calling the application file.

S45-S47). Then, in step Sj8, the editing station control unit 450 searches the command group stored in the RAM 45G from the beginning, and searches for variables N, F, P, and S. In step S49, if those variables are not found as a result of the search, the process moves to step S53,
The command group of the application file is transferred to the image processing unit 10 one by one. On the other hand, if it is determined that there is a variable, the process advances to step S5Q.

In step S50, the editing station control unit 45
When 0 first discovers the variable N, (1: Displays a comment in the message area 340 of the RT 300 asking for the file number to be entered manually, and then copies the number (+7 entries) of the variable 11 manually. Next, when the variable F is found, it is displayed in the sage area 340 to specify the image position, and the variable F is manually input by the operator.
Substitute with O, Xi and Yl. Next, when the variable P is found, the image position specification is displayed in the message area 34.0, and the variable P is manually input by the operator &iXO',
If the position specification input is related to the combination of CRC...) and LO'(...) commands, the 23-5 [5! The process shown in 'I is carried out, and if it is related only to the LO (, -...) command, the process shown in Figure 23-2 is carried out. Also,
When a strange aS is discovered, the message area 340 displays the desired message. A display prompting the operator to input M copies is displayed, and the variable S is replaced with the numerical value input by the operator.

When the operator replaces all variables in the command group with numerical values, the process proceeds to step S51, and the editing station control unit 450 performs tracing processing as shown in Figure 23-8 to change the editing form to the working area 3101. Then, in step S52, the message area 34 is displayed.
0 °' OK? " is displayed and the operator confirms whether the image editing format is as desired.The operator, for example, points the "N" key to f<1.t and confirms that
If 2 is denied, the editing station control unit 45
0 erases the screen of the CRT 300 and moves to step S37. On the other hand, if the operator, for example, instructs the ``Y'' key to set 1', the process moves to step S53, and the 1, 1 JIi collection station control unit 450 saves the screen as it is, In the command group, the next image processing unit I

The image processing section 10 echoes back the transmitted command character to the editing station system vi1 section 450, and the editing station control section 450 processes the command.
It is displayed in the status display area 380 to make the operator aware of the status of the tree system.

When the editing station control unit 450 finishes executing the series of commands, the editing station control unit 450 performs step S3? , complete routine work, and return to echo mode. If an error occurs in the process of command execution by the image processing unit °lO, the editing station control unit 450 interrupts the transmission of the command, erases the screen of the CR'T 300, and displays an error code in the message area 346. and switch to echo mode.

In addition, the processing in the two series of edit modes, that is,
In the process of command file creation, command file calling, and routine work, the operator performs step S33.
Alternatively, if the edit reset key is instructed during the input processing in step S5,0, the screen of the CRT 300 is immediately erased, and the process moves to step 537 to return to the echo mode. Also, if there is an end input, it outputs a KL command to the image processing section 10, and outputs a KL command to the image processing section IO and the editing station 40.
The online state with 0 is canceled and the process moves to step S2.

(7) Editing and transmission using the league operation unit In this system, the league operation unit 550 shown in FIG. 14 is used to read and copy original images.

It is possible to perform internal and external communication and image editing using application files. As previously mentioned, league section 500 operates in copy mode and edit mode. The operator selects one of these modes to copy,

Since the image processing apparatus of the present invention is configured with a DOX interface that performs tail-end communication of image information between this system and other systems on the DDXl line network, and a printer unit that copies image information, it is possible to read image information. , image information processing such as image editing, short-distance communication of image information using an optical fiber network, long-distance communication of image information using a DDK line, and copying of image information easily, quickly, and inexpensively. It can be carried out.

(2) The image processing control unit is provided with a buffer memory to temporarily store image information, and is also provided with a switching device to transfer image information within the device of the present invention and from other systems to this system via an optical fiber cable. Switch the flow of the image information being sent and select one or more of the memory, optical fiber interface, and printer section.

Since the image information can be transferred to each section, J2
It is possible to process T-reading, short-distance communication, and copying in parallel, and it is possible to shorten the time required to open the image.

(3) Image information transferred from other systems on the DDX line network via the DDX line network and DDX interface is stored in a buffer memory, and regarding the processing of the image information stored in the buffer memory,
The same effect as the main term (2) can be obtained.

C4) When communicating image information between this system and other systems via the oox line network, image information of a document of a predetermined size is transmitted between this system and the other system within a predetermined time. A signal RD indicating that it is possible to transmit
S and a signal RDR indicating that it can be received are sent to each other, and in both systems, the transmission direction of image information is determined from a fixed combination of RDS and RDR of both systems, so errors in the transmission direction can be avoided. can be prevented and DD
It is possible to reduce the transmission time of image information using the K line.

(5) The DDX interface performs run-length encoding on one line of image information in the vertical direction of the original image, and then performs data compression on the run-length encoded 1947 minutes of image information using a two-dimensional encoding method. , if the run-length length of image information for one line exceeds 2623, one make-up code corresponding to the required run-length length is added following the make-up code corresponding to the run-length length 2580, and then Since data compression is performed by adding one terminating code, the total number of lines of the original image to be transferred can be reduced when communicating using a DDX line. Since this can be done efficiently, the transmission time can be shortened.

(e) When communicating image information between this system and another system via the nnxU line network, the image processing control unit sends a signal CRQP requesting connection to the other system to the DDK interface; A signal CNQ requesting acquisition of the DDX line and a signal indicating that the image processing control unit cannot transmit or receive one image information within a predetermined time (a signal CNQ indicating that the image processing control unit cannot transmit or receive one image information within a predetermined time. The signals RDS and RDR, which respectively indicate that the DDX interface can be in the current and receiving state, the signal RQS, which indicates that one line of image information is being supplied to the DDX interface during the valid period, and the image information SDT are transferred. ,
The DDX interface sends signals CIP and D
A signal NRYD indicating that the DX line cannot be connected;
A signal CND indicating that the DDX line connection has been completed and communication is possible, a signal MDS indicating that the DDX interface is in a mode in which it can send image information to other systems, and a signal MDS indicating that the DDX interface is in a mode in which it can send image information to other systems. A signal MDR indicating that the mode is ready for reception, a signal RQS requesting transfer of 1947 minutes of image information, and a signal RVA requesting reception of 1947 minutes of image information received from the DDX interface or another system and demodulated. and image information received and demodulated from other systems. These signal groups enable reliable communication of image information between this system and other systems.

(7) I] When communicating image information via a DX line, once the relationship between this system and another system is determined between the calling system and the called system, both systems communicate the transmission conditions to each other, and when the transmission conditions of both systems are established, the other system is ready for transmission 4m
The calling system then starts transmitting image information for each line, and the called system monitors each transmitted line for transmission errors. When the called system discovers a transmission error, it requests the calling system to retransmit the image information after the line where the transmission error occurred.

In response to the request, the calling system performs data compression using a two-dimensional encoding method that one-dimensionally encodes the line starting from the line where zero transmission errors occurred, and then two-dimensionally encodes the following line. transmission is resumed. That is, image information can be transmitted reliably, and even if a transmission error occurs, the error can be quickly removed.

(8) The optical fiber interface converts the optical signal transmitted from other systems on the optical fiber network to the 0 column into an electrical signal, reproduces commands and image information related to image recording from the signal, and creates an image. Co-and and image information related to image recording for other systems, which are supplied to the processing control unit and transferred from the image processing control unit, are converted into optical signals and output to the optical fiber network, so one image recording is possible. Image information can be recorded without requiring any operations on the system that performs the recording.
It is possible to speed up image processing.

(8) The image processing unit (CPυ circuit block) sends a status request to the printer unit, and the printer unit responds to the status request by notifying the image processing unit of the status of the printer unit. sends a recording preparation command according to its status, and the printer section records image information in response to that command, so the image processing information forming unit side can recognize the status of the printer section. Image recording can be performed directly, and thus image recording can be performed effectively.

(10) The image processing control unit is equipped with a disk memory that can store image files, application files, and control programs for the image processing control unit, making it easy to store and edit a large amount of image information. can be done.

(11) The image processing control section sends a scan start command to the league section, and the league section scans the original image in response to the command, and supplies image information to the image processing control section. , the image processing information forming unit, and the department side can directly command the reading of the original image, thereby making it possible to read the image efficiently.

(12) The league department is equipped with a league operation section, and the application cage 3 file stored in the disk memory can be started from the league operation section, making it easy for the league department to perform routine tasks such as image editing. can.

(13) Enable image information to be sent from the league operation unit to multiple other systems on the optical fiber network and DDX line by specifying the destination, especially when sending to other systems on the optical fiber network. Now you can specify the number of copies for each destination, so
Picture 1! Information can be transmitted easily and quickly.

(14) The editing station is equipped with a command menu section through which the operator inputs a group of commands for image editing, and a digitizer through which the operator inputs the coordinates of the image to be edited, making it easy to input information for image editing. It can be carried out.

(15) The editing station is equipped with a display means such as a CRT, and information for image editing and messages generated from the image processing control section are displayed on the screen of the CRT, so that the operator can You can proceed with your work while interacting, you can easily edit images and create application files for image editing, and even if there is an error in input information, you can quickly deal with it. It can be done efficiently.

(1B) A command to start the reader section is provided in the command menu section of the editing station, and by inputting that command, it is possible to have the league section perform the operation of reading the document image. In cases where it is necessary to cause the unit to perform a reading operation, the operation can be executed simply by operating the command menu unit, thereby simplifying the image editing work.

(17) Since the command menu section is provided with a command that allows you to select a dither pattern, such a selection can be made only by operating the command menu section.
The same effect as 16) can be obtained.

(18) When reading a document image, the command menu section has commands for specifying areas to be shaded and dithered in the image, greatly increasing image processing ability and making the work easier. can be done.

(18) A command to start the printer section is provided in the command menu section, and the printer section can be manually operated to perform image recording operations using that command. Therefore, it is possible to perform recording operations on the printer section during image editing work. In cases where it is necessary to perform this, an effect similar to that of upward tilt (1θ) can be obtained.

(20) The command menu section includes a command to input the file number as the file name of the image file, a command to register the image file with the file name in the disk memory, and a command to register the registered image file in the buffer memory. Since a temporary storage command is provided, image editing can be performed easily, reliably, and quickly.

(21) Since the area on the digitizer and the address of the buffer memory are made to correspond, image editing can be easily performed without errors.

(22) When editing images and creating editing programs, the CART display screen displays what the operator will do next, so it is easy for operators with no experience in image editing to You can also understand the operating procedures and edit images easily and quickly.
