Description

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

2. Description of the Related Art Conventionally, as a contact image processing device, a copying device as a means for duplicating a document image, a facsimile device as a means for transmitting a document image to a remote location, etc. have been widely used. The -9 general copying apparatus currently in use is capable of copying an image of the same size as the original, enlarging it, or reducing it. Alternatively, if it is necessary to change the image 7) S degree, the density can be changed uniformly over the entire reproduced image. However, such image processing functions alone may not be sufficient to meet user demands.

On the other hand, it is possible to convert a document image into an electrical signal and read it more, process the image information converted into an electrical signal, extract a part of the document, and copy it, or combine multiple images, or , a copying device equipped with image editing functions such as changing the image density of only 1/“:h of the original has been proposed.However, as the copying device is equipped with many such functions, the device becomes complicated. Moreover, the problem arises that the copying operation becomes complicated and the image processing time becomes longer.

On the other hand, with facsimile, the original image can only be sent to a remote location using a telephone line, and if it is necessary to make a copy at the same time as sending the original, an appropriate copying device must be used in addition to the facsimile machine. There are issues that need to be addressed. 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.

Purpose An object of the present invention is to provide an image processing device that eliminates the above-mentioned problems and can perform image processing such as image editing, short-range communication of image information, and long-distance communication easily and quickly, and at low cost.

10 processor 8o-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 decoder/sofa block 80-4.

The bus arbiter 80-2 couples with the multipath 30 via the signal line 80-108 in accordance with the status signal supplied from the I10 bus 80-1, acquires the right to use the multipath 30, and obtains the right to use the multipath 30. When signal line 80-10? An address information transfer enable (8EN) signal is output to the bus controller 80-3 and address/data buffer 80-4 via the address/data buffer 80-4. In this embodiment, an Intel 8288 manufactured by Intel Corporation is used as the path arbiter 80-2.

When the bus controller 80-3 performs DMA transfer from the buffer memory 2o to the disk memory 80 via the signal line 80-110 to the multipath 30 when the AEN signal is supplied from the path arbiter 8o-2 (read mode ) outputs the memory read (MRDC) signal, and when performing DMA transfer from the disk memory 90 to the buffer memory 20 (write mode), outputs the memory write (MWT) signal.

Provides data transmit/read (DT/R) signals. The signal line 80-112 from the bus controller 80-3 to the synchronization signal generation circuit 80-7 is an I10
When the processor 8o-1 accesses the internal bus 80-5 in read mode, the Ilo read command (IORC) signal output from the bus controller 80-3 and the read-only memory (R
OM) When fetching the microprogram stored in the bus controller 80-8, the interoperable acknowledge (INTA) signal output from the bus controller 80-3 and the above-mentioned ALE signal are transmitted. As this bus controller 80-3, for example, an Intel 8288 manufactured by Intel Corporation is used.

The address/data buffer block 80-4 includes two address/data buffers, each having a signal line 80-4.
It is coupled to multipath 30 and internal bus 80-5 via 115 and 80-118, and receives and passes address information and data information to and from these buses.

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

80-8 is a clock generator; 1. Based on the reference oscillation output from an external crystal oscillator, etc., a clock signal of a predetermined frequency is sent to the I/O via signal lines 80-120.

and I via signal line 80-121.
10 processor 80-1. An initial reset signal at power-on and a manual reset signal are output to the path arbiter 80-2 and the bus controller 80-3. Further, the clock generator 80-4 receives a transfer acknowledge (XACK) signal as a recognition response to the MWTC signal and the MRDC signal from the multipath 30 via the signal line 80-122, and the multipath 30 enters the wait state i. and whether the wait state has been released or not is determined, and based on the determination signal, a bus ready signal is output to the I10 processor 80-1 via the signal line 80-123.

The synchronization signal generation circuit 80-7 confirms the response of the ROM 80-8 using the above-mentioned IORC signal and INTA signal and the chip selection signal supplied from the address decoder 80-10 via the signal line 80-125. Generating a signal and providing this signal to clock generator 80-6 via signal line 80-128 enables I10 processor 80-1 to proceed to the next operation.

ROM 80-8 stores a microprogram for I10 processor 80-1. ROM from internal path 80-5
The signal line 80-130 leading to l30-8 is an address signal line 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. The signal line 80-131 leading to the ROM 80-8 is
This is the data signal line of 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 path 80-5 and the signal line 80-135.
-8 selection signal is sent to RO via signal line 80-125.
It is output to M80-8 and the synchronizing signal generation circuit 80-7. From path controller 80-3 to address decoder 80
The signal line 80-113 leading to -10 transmits the S2 signal, which is a type of status information. That is, the S2 signal is latched in the address/data buffer block 80-4. signal, address decoder 80-1
0 performs that identification.

Here, the operation of the DMA controller 80 in receiving and passing address information and data information to and from the multipath 30 and the internal path 80-5 will be described. First, a case will be described in which the multi/hess 30 and the information are received and transferred. When the I10 processor 80-1 outputs address information to the address/data buffer 80-4, the path controller 80-3 outputs address information to the address/data buffer 80-4.
When the ALE signal is applied to address/data buffer 80-4, address/data buffer 80-4 latches address information into the address buffer. Also, after the latch, the bus arbiter 80
-2 acquires the right to use the multipath 30, the bus arbiter 80-2 supplies the AEN signal to the address/data buffer 80-4, and
0-4 multipath 30 for latched address information
Output to. Here, if the DMA controller 80 is in write mode (36) and the multipath 30 has been acquired, the I10 processor 80-1 outputs data information to the address/data buffer 80-4, and The address/data buffer 80-4 is connected from the path controller 80-3 to the D
Upon receiving the EN signal, it outputs data information to multipath 30. In contrast, when DMA controller 80 is in read mode, address/data buffer 80-4 reads data information on multipath 30 and provides the data information to I10 processor 80-1. F1] Reading of data information by the processor 80-■ is transmitted from the disk memory 90, which is the data transfer destination, to the I10 processor 80-1. This is done by confirming the XACK signal.

Next, the operation of the address/data buffer 80-4 connected to the internal path 80-5 is almost the same as described above, but in this case, when outputting address information to the internal bus 80-5, the bus arbiter 80-4 -2 by AEN (No.

It has a disk controller circuit (not shown) inside, and this circuit is connected to the internal path 80-5 of the DMA controller 80 via the data/hes 80-140.
It is connected to a synchronizing signal generation circuit 80-7 and an I10 processor 80-1 via Shingas lines 80-142 and 80-143, respectively.

Data buses 80-140 convey command information, result information, data information, and status information;
Assign all addresses to the three [〆f-reports] of party i xll
The three pieces of information are sequentially input/output to the disk controller circuit to be distinguished. Also, one address will be assigned in China and Germany for status ↑1'1 report. Here, the command information is information that specifies the address of the disk memory 80-hi and the number of 7 hates, and the result information is [1 This is information indicating the results.

Signal line 80-142 is command busy (CBIISY)

The mouth 1 path 80-7 identifies the above-mentioned three information and status information.In addition, the information of I N1 consisting of command information 017, result I information and data information, Status information differs in the timing at which the data becomes ready, and also in read mode and ;l) include mode.
Therefore, the synchronization signal generation circuit 80-7 connects the signal line 80-1

The bank space of the buffer memory is 896 kilobytes from address 10000) to EFFFFH, but as mentioned above, the buffer memory circuit block 20
The storage capacity of - is 1995840 bytes, which cannot all be stored in the bank space of the /header memory. The buffer memory space is then divided into three banks: bank 0. Divided into bank 1 and bank 2,
The bank is switched by the puncture switching signal outputted from the CPU four-way block 10 via the signal line 132 (see FIG. 4 and FIG. 6-2), and the designated bank is switched to the 8th bank.
Assign to the memory map as shown. This process of division and overturning will be described in the explanation of Figure No. 1 and Figure 9-2.

The program space for the intersection 11 is the CPU circuit block 10.
Of the RAM (32 kilobytes 1-) 10-3, 8 kilobytes) are used. The work RAM space is 24 kilobytes, which is obtained by subtracting 8 kilobytes used for the communication program from the 32 kilohydride RAM 10-3 in the CPU circuit block 10.

Figure m8-1 shows the address map of the panf memory 22 in the buffer memory circuit block 20. This buffer memory 22 is A4 size (287mm x 210mm)
It has the ability to store information decomposed into 16 pixels per 1 mm of original documents. The reader unit 500 main scans the A4 size document in the vertical direction (297 mm direction), and then the CCD 570.58θ and 590 scan the A4 size document at 18
The image is divided into pixels and 4752-bit pixels per scan are supplied to the image processing control section 100L. Also, league part 5
00 sub-scans the document in the width direction (210 mm direction),
CCD570, 580 and 590 are also 1m in this direction.
Since 1B lines are scanned per m, the document has 3 lines in the width direction.
360 lines are scanned. Therefore, an A4 size document is decomposed into 15,586 to 20-bit pixels, and the image processing control unit 100 stores 4,752-bit pixels in series.
Supplied 360 times.

The procedure for locating the image information supplied in this way and storing it in the buffer will be explained. Masu, A4
Size I! :jl hJ+ is composed of lmm x 1mm square unit blocks [komin - 111 blocks, 82370 blocks.

One r15.4i”t block contains 18 bits.
If there are 8 lines, or 256 bits of image information, and one word is +13 bits i in the vertical direction, and one address is given to that l word, one medium block has 18 addresses. It is composed of a group of pixels. The serial image information of 4752 bits for the first line, that is, the first line of the document scanned, corresponds to 1 mm in the vertical direction of the document! The first 16-bit pixel group is divided into pixel groups of 16 bits each and is supplied to the image processing control unit 100. 0
0010) address 1, and thereafter, pixel groups of 16 bits each are sequentially arranged at address 00020H at every 16 (IOH) address.

Address θQO3QH..., is stored as address 01280H.

Addressing of each line to the panzer memory 22 is determined by the CPU circuit block IO using the address counter 21-6.
This is done by setting the initial value to . Also, when outputting the image information from the buffer memory 22 to the printer section 600, it is read out every 18 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
1536 lines from line to 1536th line (@
Hmm in the direction) is stored from address 0OOOOH to address 6F5FFH, and this address space is stored in the buffer memory 22-
The bar of 1- is set to 0.

Next, do 1536 lines from i 1537th line to 3072nd line in the same way as bank O? It is stored from address 00008 to DF5FFH, and this address space is designated as bank 1 of breadboard memory 22''-. Furthermore, the third
288 from line 073 to line i'53380
The line is stored from address EOOOOH to address F4EIFH4, and the area between these addresses +, :, -+ is set as bank 2 of /henfa memory 1) 22J-.

If you use the method of adding 1 address to 1 word of image information and storing it as shown below in 1-1-, 1) of ]mmXlmm is used.
(The buffer memory 22
-1: The entire area of an A4 size document can be stored at consecutive addresses. As a result, when the operator specifies the image processing area in millimeters using the console S++ 200, when registering the specified area in the disk memory 80, all that is required is to set the starting address and ending address of the specified area to 1. DMA transfer can be performed, and image information can be transferred at high speed without going through the CPU circuit program 10.

In other words, by specifying a set of the first address and the last address, the image information of 16 main scanning lines (f: 1 mm width) is transferred by DMA, so the number of DMA transfer address settings is reduced, and the transfer speed is reduced. Speed-up can be achieved.

Furthermore, storing image information in this manner is more effective when extracting and editing one image information because the addresses are continuous from the right side to the left side of the image to be extracted. For example, when extracting image information whose length in the vertical direction is 2On+m, the CPU circuit block 10 only needs to set the address 20 times.

Furthermore, since addresses correspond to positions on the original image in units of 1111, the operator can conveniently specify the position on the original in units of mm when editing the image.

In addition, in this example, it has a readability of 16 bits per 1 mm (:CD5?0.580 and 590C were used, so it was decided that one address corresponds to 18 bits in the vertical direction, but the bit corresponding to one address The number may be other values depending on the capabilities of the CCD 5?0.580 and 590, and it is of course possible to obtain the same effect by setting the address in units other than Inff1, for example, units of inches.

It corresponds to the address space of address 39C3EH. The multipath 30 has a 16-bit data bus and a 20-bit address bus, but the area that can be accessed by this multipath 30 is 1 megabyte. In other words, 106 pieces of 8-bit data can be accessed, and when accessing 16-bit data, it spans 2 addresses, so in this case, as shown in Figure 9-2, 16 bits of data can be accessed.
Consecutive addresses are assigned every i address for bit data, and 16-bit data is input/output only when an even address is accessed.

Since the actual address in the pack memory circuit block 20 is the address shown in FIG. 9-1, the multipath 3
When accessing the buffer memory 22 from 0, the address in FIG. 8-2 is converted to the address in FIG. 9-1 by the address converter 21-26 in the buffer memory circuit block 20, as described above. . The address converters 21-213 allow the address area of the buffer memory 22 to be set in any address space.

(', 3.5) Disk Memory FIG. 10-1 (A) shows the physical address structure of the disk memory 80. 81 is a drive, which has numbers 0, 1, . . . corresponding to the individual disk drives. ...and number it. In this embodiment, only one disk device, that is, a drive numbered 0, is used. The drive 91 has three heads 92, and each head 92 has 354 tracks 83.
Each track 93 consists of 18 sectors 94, and each sector 94 can store 512 bytes of data. Therefore, the storage capacity of disk memory 90 is approximately 10 megabytes.

In the disk memory 80 having such a configuration, the first

The sequence number SN, head number IN, and track number TN have a relationship determined by the following equation (1).

5N=3X TN+HN (Start, HN=0~2.
TN=Ci ~353) (1) That is, when a certain sequence number SN is determined, the i/rack number TN and head number HN are determined correspondingly, and the addresses of the head 92 and track 83 to be accessed next are determined from the previous one. These are the head number and track number obtained corresponding to the sequence number SN+1, which is the sequence number SN defined in 1 plus 1. And; Sectors 84 in rack 93 are accessed in ascending order of sector number 5CTN.

FIG. 10-2 shows an index table provided in a predetermined area within the disk memory 9o, and the use status of the disk memory 9o is managed by this index table. In this embodiment, among the sectors 94 with head number HN=O and track number TN=0, the sector with sector number 5CTN=O-13 is used as the area of the index table. Sectors with numbers 5CTN=0 to 8 are assigned to the sector bit map table 94A indicating the usage status of each sector on the disk memory 80, and sectors with numbers 5CTN=9 to
Allocate 13 sectors to the file index table for file management. Sector number 5CTN=1)~13
The sector is written to addresses 8.000H to 78FFH in the fixed area of RAM 10-3 by a program (open program) that reads the index table into RAM 10-3 in the CPU circuit block 10, and is subjected to a predetermined operation. , RA old 0-3 is written to the disk memory 80 again by a program (close program) that stores the fixed area of RA old 0-3 in the disk memory 80.

As shown in FIG. 10-3, the sector bitmap table includes five sectors of the area 94A in ascending order of sequence number SN.
Separate writing III into 1062 4-byte blocks from N-0 to 5N=1081, 1 per block
Data indicating the usage status for a track, that is, for 18 sectors, is stored by allocating 1 node per 1 sector. For example, the data indicating the sector usage status is as follows:
If a certain sector is in use, 1° is stored in the sector bit corresponding to that sector, and 0′ is stored in the sector bit if it is unused.

When registering a new data file in the disk memory 90, find an area where the number of consecutive sectors required for registration are empty, and enter the sequence number SN and sector number 5CTN corresponding to that area. 1J, 11 bits are stored in the sector bit corresponding to that sector. Conversely, when erasing a data file, 0'0' is stored in the sector bit indicating the corresponding area. However, 1°" is stored in advance in the bit corresponding to the index table, that is, block 0, and writing to block 0 is prohibited to prevent data files from being erroneously registered in the index table.

The file index table is stored in disk memory 80
It manages three types of files registered in the system: image data files (image files), application files, and control programs for this system. Assuming that the image file is file type 0 and the application file is file type 2, the management status of these files using the file index table is shown in the first O-

It consists of four blocks of 2 bytes each, numbered 8, and is provided when the disk memory 90 is initialized to store 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 90, and in this embodiment, the total number is 50 (328).

(26H) bytes. The current B number stores the number of files registered in the disk memory 90, and stores the number of files registered in the disk memory 90.
When registering a new file, compare it with the number stored in the MAX size, and if the number does not exceed that number, it will be added by 1 and the new registration will be performed, and if it exceeds the number in the MAX size New registrations will not be accepted without being added to the list. Conversely, when deleting one file that has already been registered, the number stored in the current number B is decremented by 1, and the file is deleted from the disk memory 90.

FIT2 and FIT3 indicate file index blocks for file type 0 and file type 2, respectively, and each stores 38 byi* data. In FIT2 and FIT3,

File No. is a 2-byte 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 90. The file type is a 2-byte area in which data of the above-mentioned file type °°0°'' or °°2°' is written. The puncture and address in FIT3 are the CPU circuit block 1O-

This system encodes image information using MH encoding and IIIR encoding.
The method of encoding and transmitting it to other systems is CI
The following points should be considered when applying Recommendation 7.4 to the present invention.

(1) With the wood invention device, the vertical direction (2
97 mm direction) is one line, and the resolution is 16 bits/mm, so the maximum run length, i.e.
When the lines are all white or all black, the run length is 4752, which exceeds the maximum expression range of 2823 (=2580+83) of the extended M)1 code.

(2) In the tree invention device, the parameter K is set to infinity.
Transmission is performed using the dimensional encoding method. That is, for an A4 size document, the first line that is first transferred to the DDX interface 60 is M)I 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. That is, (i) the transmission time is shortened by reducing the number of transmission lines. and,(
ii) By reducing the overall moving 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 set the parameter K to a small finite value and save the time of repeating MH encoding every time, and the parameter K is set to infinity. The reason for this is that the image information to be transmitted has already been binarized by the COD driver 50 and stored in the buffer memory 22, and the parameter K is set to a small limit value to reduce the reading error. This is because it is lost.

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

First, image information for 1 life (4752 bits) transferred from the buffer memory 22 via the signals m and 137 is transferred to the line buffer Go via the data/clock interface 60-1 and the write switch 60-3. −
4, 80-5 or 80-6. This image information is transferred to line buffer 130-4, θ0-5 or 6 at a transfer rate of 1 bit per 0.1 microseconds (ps) in synchronization with a IO megahertz (MHz) clock signal.
Transferred to 0-6. That is, the transfer time for one line of image information is 475.2 pLs. The image information of the first line that is transferred first is first supplied to the line buffer 60-4 by the switch 60-3, and when line pack arrow 0-4 finishes storing the image information of the first line. ,! , l] converter 80-7 is the line buffer 60-
4 and line buffers 60-5 and 60
-6 is closed and the stored image information is fed to the RL counter 60-8 for which the white and black run lengths are counted and the first line of which is run length encoded. Image information is RLM MH/
It is converted into an M)I code by an MR converter eo-to.

While the line buffer 60-4 is outputting image information, the switch 60-3 closes the gates to the line buffers 130-4 and 60-6, opens the gate to the line buffer 60-5, and opens the gate to the second line buffer 60-5. Line image information is supplied to the line/thin edge 60-5. If all the image information of the first line is MH encoded, the image information of the second line is supplied to the RL forward/reverse counter 60-7 by the switch 60-7, and the relative pixel information from the first line is The changed position is counted and converted into MR by RL8 MH/MR converter 80-10.
encoded. The image information of the third line transferred to the line buffer 60-6 is also processed in the same way as the second (67) line.
, 130-5 and 60-8, the image information is outputted from R1, M MH via RLjE/inverse counter 60-7.
/ is supplied to the R converter Go-10 and subjected to MR encoding.

Next, the run-length encoded image information supplied to the RL→MH/MR converter 80-10 is MH encoded or MR encoded and compressed.

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 H code.
Expand further.

Represents HBr. That is, when RL<84, it is represented by one terminating code.

If 64≦RL<2580, it is represented by one make-up code and one terminating code.

(2) When run length RL≧2580, the make-up code 2560 “00000001111” is regarded as a special code and handled as shown in (68) in the following (a) and (b).

(b) When 2623<RL≦4752 Following the make-up code of 2580, one more make-up code is added as required, and then one terminating code is added. That is, in case (2),
The 2560 make-up code is immediately followed by a terminating code of the same color (a), and the 2560 make-up code is followed by a make-up code of the same color, followed by a terminating code (b). be.

6 is a diagram showing the direction (arrow) of signals between the Dx interface 60 and the Dx interface 60. FIG. Here, FG and SG are respectively,
This is a safety ground wire and a signal ground wire.

The call request signal (CRQP) is processed by the image processing unit 10 using DDX.
This signal requests the interface 80 to connect (call) with another system, and this signal is a connection raw signal (CH
D) is deenergized at the same time as it is energized, and when the connection failure signal (NRY[l) is energized, it is treated as invalid. The call signal (CIP) is a signal indicating to the DDX interface 60 or the image processing unit 1O that a call has arrived from another system, and the processing for CND and NRYD is similar to CRQP.

The dial number signal (DLN) is changed to the old pattern at the same time as CRQP is activated, and transfers the 7-digit station number of the other system.

The connection request signal (CNQ) is a signal in which the image processing unit 10 requests the DDX interface 60 to connect to the []DX line, and is activated at the same time as either CRQP or CIP is activated, and NRYD is activated. It is considered invalid when it is in force. Also, while it is necessary to seize the line, CN
Q is energized, and de-energizing CNQ will disconnect 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. In NRYD, the DDX line 800 is busy, and the not ready switch of NCU 302 is 4=1.
Indicates that the line cannot be connected, such as when the line is activated. The NRYD line is always energized or deenergized, depending on the state of the line connection, whether active or not, respectively. Also, after CRQP was energized,
If CNII is not updated to the old pattern even after a certain period of time has passed,
The image processing unit 10 determines that connection is impossible (step 7).

Indicates 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. The ready-to-send signal (RDS) and the ready-to-receive signal (RDR) indicate that the image processing unit 10 can be in a state where it can transmit and receive image information for one A4 size document within 6 seconds, respectively. , CNQ activation and RDS or RDR

The transmission data request signal (RQS) is energized and deenergized at regular intervals, and the DDX interface 60 requests the image processing unit IO to transfer one line of image information.

When RQS is activated, the image processing unit 10 changes the transmission data valid signal (SVA) to the old pattern and transfers one line of image information (SDT) from the buffer memory 20 to the []I]X interface 60. . RQS is de-energized upon completion of its transfer. The RQS repetition period is set longer than the minimum transmission time. SVA is deactivated in response to RQS, indicating that SOT is allowed to be sampled in synchronization with the transmission clock (SCK), and is deactivated upon completion of SDT transfer. The RVA is activated at regular intervals, requests the DDK interface 60 to receive one line of decompressed image information (RDT) received from another system, and sends the RDT.
Indicates that sampling is allowed in synchronization with the reception clock (RCK). The repetition period of RVA is R
It is similar to QS.

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 8001, the transmission direction is the calling system (calling station) and the called system (calling station). The calling station) compares the RDS and RDR and makes a decision as shown in Figure 12-3, thereby preventing errors in the transmission direction.

In other words, in Figure 12-3, A.1 situation m;
, when only the calling side's RDR and at least the called side's RDS are powered, and when the calling side's When only the RDR, RDS, and RDS on the called side are activated, the transmission direction is from the called side to the calling side. In addition, when only the calling side's RDS and at least the called side's RDR are enabled, and when the calling side's RDS and RDR and at least the called side's RDR are
When energized, the direction of transmission is from the calling side to the called side. Transmission is disabled in combinations other than those described above for RDS and RDR of both the calling and called stations.

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 informs each other of the transmission capabilities of the calling and called stations, ie, RDS and RDR. For example, the transmission format is “OOOOORDS RDRI
The 8 bits of ``O'' will be sent sequentially from the most significant bit to the least significant bit, and both stations will transmit from the RDS and RDR of the tree system and the RDS and RDR of the other station as shown in Figure 12-3. Determine direction.

RDY is a ready-to-transmit signal, and its transmission format is, for example, "00010010" to be sent in the same way as in the case of IDS, and the IDS intersection 1. Indicates that the preparation for transmitting/receiving image information for one document in the transmission direction determined by .) is complete.

Old 11 is MH encoded first line image information, H
F! 2 to MRn+1 (1≦n≦3360) are MR encoded image information of the 2nd to (n+1)th lines, and MHn is M)! encoded image information of the nth line, and M

This is Shihakuμ'' information for the 3360th line, Agu ~ MR3
380 indicates image information for one A4 size document.

RTQ is a retransmission request signal, and if there is an error in the received one line of image information, that is, if there is an error in the received one line of image information, the length of one line of the demodulated image information from the called station is 0. or 4752 bits, this information is stored in the called station's buffer memory 2.
2, the called station issues a retransmission request to the calling station.

RTC is a transmission end signal, and the calling station
Line end in T, 4 recommendation by CI TT ☆11A
(75) A signal obtained by adding 1 to EOL is transmitted to indicate completion of transmission of one image's worth of image information.

The DCN is a line disconnection signal, and its transmission format is 1, for example, ``01000010'', which is sent in the same manner as the IDS to notify phase 71' of line disconnection.

After the line connection 1r1, the calling and called stations start sending IDSs to each other, and repeat this process at least three times until the stations are ready for the transmission mode. Here, for example, at time A, if the direction of transmission cannot be determined, both stations determine that transmission is impossible (see Figure 12-3) and send DCN to the other station to 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, the called station enters the receiving state without sending control signals to the calling station, and the calling station enters the transmitting state.

(76) When transmitting image information for one A4 size document, for example, if a transmission error occurs in the image information of the nth line at time E, the called station will notify the calling station. In response, the calling station MH-encodes the image information of the n-th line, sequentially MR-encodes the (n+1)th line to the 3360th line, and transmits them.

When the transmission of the image information is completed in this way, the calling station sends the RTC to the called station, and then both stations send the IDS to each other, and at this time, the transmission conditions are set as shown in Figure 12-3. If the above is satisfied, then other image information is received from time point C. Conversely, if the condition is not met, D
Sends CN and disconnects the line.

(6) How to edit images Image editing goes to 7 Rahua memory 22 and Dinuku memory 80
DMA transfer is appropriately performed between the host and the host. That is, the image information for one A4 size original stripe (87) read by the league unit 500 is stored in a predetermined address of the buffer memory 20, and the image information -Sl() is sent via the DMA controller 80. Then, the image information previously stored in the disk memory 80 is stored in the buffer memory 22 again.
By returning to the desired address space of No. 2 and duplicating the image ψ data in the printer unit 600, a duplicate with unnecessary portions of the document trimmed can be obtained.

, 2, image editing such as image position change and cropping is performed according to an image processing program created based on commands (described later) manually entered from the command menu section 220 shown in 3-21A. Such an image processing program can be stored in the disk memory 80, and the stored image processing program is defined as an application file. Image information stored in the disk memory 80 is defined as an image file. When registering these files in the disk memory 90,
If ■ As mentioned above, the file has two digits as the file name! 88) Ask for the file number and indicate whether the file can be deleted or not.

FIGS. 16A, 16B, and 16C show examples of in-depth image editing. First, the league unit 500 reads a single document L1 shown in FIG. Manuscript/1 front section 240
Then, specify point A and point B with the stylus pen 280, extract the image information within the old range from the stored image information, and add the file number to the old image information, for example.
01" and register it in the disk memory 80. Similarly, the second document L2 is extracted by specifying the 0 point and the D point, as shown in FIG. Image information M2
Then, ask for the file number ``02°'' and save it to disk memory 8.
Register to 0. Next, erase all the buffer memory 22, specify the E point and the F point as shown in the same figure (C), and erase the old and The image information in M2 is transferred to the address spaces corresponding to the areas N1 and N2 of the buffer memory 22, respectively.In other words, the image information for one A4 size document is stored in the buffer memory 22 as the old image information and N2 is stored in a state where it is arranged as shown in FIG. 16 ('C).

The contents of the buffer memory 22 are transferred to the printer section 600 and repeated, thereby producing a desired edited image L3.

(6, 3) Editing procedure 1) Figure 19, Figure 20, Figure 21, and Figures 22-1 to 22-2
A procedure for editing image information using the editing station 400 will be described with reference to FIGS. 2-6.

When the editing station 400 starts up, first step S is performed.
At step 1, display division of the CRT 300 screen and initialization of system constants are performed. The CRT 300 has a screen 301 that can display 40 horizontal characters and 24 vertical lines. No. 22-1
The figure shows an example of display division of the screen 301, where the first
A working area 310 from the line to the 18th line is used to display characters transferred from the image processing unit 10 to the editing station 400. 320 on the 20th line 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 on the 21st line is a mode display area, which displays in which mode (described later) the operator is using the editing station 400. 340 on the 22nd line is a message area, in which the editing station control unit 450 displays to the operator commands and parameters to be input next, error codes, etc.

350 on the 23rd line is a user input field, which monitors characters such as file numbers input by the operator.

360 on the 24th line is a status display area, which is an area for displaying the status of the image processing unit 10 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 carriage return code is acknowledged, and the command is sent back from the image processing unit 1°. 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 the message area 340 is all blue,
The operator's online requests, i.e. “REQUES”
“NOT REA” as a message that accepts the T” key.
DY, ENTER REQUEST KEY" is displayed, and the input of the °'REQUEST" key is waited for in step S2.

Editing station 400 operates in two main modes: echo mode and edit mode. In the echo mode, the character input by the operator via the console section 200 is transferred as is to the image processing section 10, and is also transferred from the image processing section 10 to the editing station 400.
In this mode, the characters transferred to the CRT 300 are displayed as they are on the CRT 300.

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 input by the operator is
First, it is temporarily stored in the RAM 45B in the collection station control section 450, and after being arbitrarily modified by the operator using the CRT 300, it is transferred to the image processing section 10. In addition, in the edit mode, the period during which an application file transferred from the disk memory 90 to the edit station control unit 450 via the image processing unit 10 is received is particularly referred to 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 it is determined that the mode is echo mode, the process proceeds to step SB, where the echo-packed character from the image processing section 10 is displayed in the working area 310, 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 character is being used by the working area 310 or screen editor in this mode, the character is displayed in the user input area 350, and the process proceeds to step SG). If it is determined that the mode is the command mode, the process immediately proceeds to step SD, where it is determined whether or not reception of the application file has been completed. Here, if the determination is affirmative, the process moves to 7 steps SF, sets the application file reception completion flag, 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 45B, and the process proceeds to step SG.

By instructing the "REQUEST" key, the process advances to step S3, where the editing station 400 is set to 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, startup of the image editing program is confirmed, and if the determination is negative, the process moves to step S4, and if the determination is fi fixed, the process moves to step S6. In 7 step S6, CR
For example, the screen of the T300 may be completely black, and the message area 340 may display "0N-LINE'" in green text to inform the operator that the request to start the editing program has been enabled, and also to indicate the mode. Display area 330 displays "EC:HOMODE" to inform that editing station 400 operates in echo mode, and waits for command input in step S7.

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. The process moves to S25 or S30.

In the echo mode, there is no screen editor available for the CRT 300, so if there is an input to the key group 229 related to screen editing, it is processed as invalid manual input in step S10, and the input is processed in step S7.
and wait for the next input. Further, the same process is performed when the keys for ending the edit mode, that is, the edit reset key and the edit note key are input.

Key 1! "If the command character in t222 is input, the process goes through step 315 and then goes to step 5ll (
The command entered by one person is transferred to the image processing unit IO, and the system operates according to the command. For example, as shown in FIG. 23-2, when the "RE" key is pressed manually, the characters "RE" are displayed on both sides 301, and when the carriage return key 225 is pressed, a league drive signal is supplied to the league section 500. The original image is read.

When the coordinate input request key 227, that is, the ``° position specification'' key and the area specification key is specified, step S2
0, and it becomes possible to indicate 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 "E" appears in the message area 340.
NTERTOP RIGHTPO 5 ITION" is displayed, and the left half of the working area 310 is colored white to violate the operator's instructions for point A (see Figure 1O-5), and the left half of the working area 310 is colored white. The image information editing area 315 is displayed.

When the operator indicates point A, as shown in Figure 22-3, a coordinate display line 312 is drawn, for example, in green, on the image editing area 3]1, in the vertical and horizontal directions of point A' corresponding to point A. Also, the X and Y coordinates of point A, that is, x0 and YO, are displayed in mmr 1 on the user input canister 350. Next, “ENTE” is displayed in the message area 330.
RBOTTOM LEFT PO3ITION'" is displayed to prompt the operator to input point B. When point B is input, in step $21, the vertical and horizontal directions of the edited image are calculated from the coordinates of point B and the coordinates of point A. Length x 1 and Yl are calculated, and in step S22, the editing area specified by inputting the A point and B point is converted to the image editing area 311'' as shown in Figure 22-4. For example, the area 313 is displayed in red. At the same time, message area 33
'OK' for 0! AREA l5RECQGNIZE
11'' is displayed to notify the operator of the completion of editing area specification, and the user input canister 350 is displayed with XO, YO.
, XI and Yl are expressed in mm units. Next, the process moves to step S18, and these numerical values are sent to the image processing section 1.
Transfer to 0.

Also, if you want to specify a position and edit the image, press the ``Position Specification°°'' key. In this case, specify only one point,
That is, the force at point A in the case of area specification is specified. When that point is input, the coordinate display line 312 is displayed in red, for example, and x0 and YO are displayed in mm units on the user input canister 350. When the Jluf collection station 400 or designated position is recognized in this way, the message area 3

and YO number i171 information is transferred.

When the area specification or the digit 11 specification is completed, step S7
The editing station 400 returns to the console section 2 again.
Wait for input from 00, and by inputting a new command,
The command and the designated coordinates that were displayed before execution of the area designation or position designation are displayed in the working area 310F, as shown in FIG. 22-2. Also, "area specification"
If the operator instructs another command key after instructing the key or the ``position specification'' key and before inputting coordinates, the system waits for input of the seat frame for area specification or position specification. is canceled, press the ``Specify area'' key or °
The command that was displayed 17 before the instruction of the ``position designation'' key is displayed in the working area 310.

To release the editing station 400 from the control of the image processing section 10 and cancel the online state, a KL command is input using the alphabet keys 223. At this time, the process proceeds to step 5213 via step S25,
The character information of "KL" is output to the image processing section 10 to request termination of the image editing program, and step S2?
Proceed to. In this step S27, if it is detected that the editing program of the editing station control section 450 or the image processing section 1O has not been completed, a negative determination is made, the manual effort 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.

Manpower of 228 keys related to application files,
That is, when there is an instruction for the ``Standard Work'' key, the ``Application File Call'' key, and the ``Application File Creation Park'' key, the editing station 400 performs the operations in step S30 as shown in FIG. Set to edit mode.

Here, the ``Create application file'' key is a key for instructing when creating a new application file, and the ``Call application file'' key is used to recall and modify an application file recorded in the disk memory 80. This is a key used to instruct when adding an image, and the ゛key is used to instruct when an application file is called up and its command strings are sequentially transferred 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, since application files are handled, it is essential to specify the file number. Therefore, in any case, first in step S32, the editing station control unit 450 makes the screen of the CRT 300 blue, and changes the message area 340G,
: ”ENTERFILE NO, AND CARRI
"AGE RETURN" is displayed and the operator is requested to input the file number.Then, "EDIT MODE" is displayed.
” is displayed in the mode display area 330 to inform the operator that the editing station 400 is in the edit mode, the screen of the CRT 300 is returned to black, and the following processing is executed in accordance with the respective processing procedure in each case. .

First, the procedure for creating an application file will be described.

When the application file number is input in step S32, the editing station control unit 450 displays 'EN' in the message area 340 in step S40.
TERMENU! ” is displayed to prompt the operator to create an application file.Then, the cursor 302
is blinked in the left-1 corner of the working area 310 to wait for command input, and then the operator inputs a desired command group in sequence to create an editing program. 1
By inputting one command I7 and adding a carriage return, the command is transferred to the RAM 456 in the editing station control section 450, and is then transferred to
Displayed in working area 310. In this way, the input commands are stored in the RAM 45B, so by instructing the screen edit keys 229, you can erase the line or character on which the cursor 302 is flashing, or delete a new Insertion of lines or characters, movement of the cursor 302, etc. can be performed. If the creation of new lines in the editing program exceeds the number of lines that can be accommodated in the working area 310, the working area 31
0 is scrolled up one line at a time, and the cursor is 30
Working area 31 can also be reached by moving down and moving down.
θ is scrolled up and down.

When creating an application file, area designation input processing is performed in the same way as in echo mode, but position designation input processing is performed as follows. The position specification input when creating an application file is 0 (
This is related to the input of the coordinates XO and YO of the ADH(...) command that is input next to the ...) command, so make sure that the LO(...) command has been entered in advance, and Search for CR(...) from the command group that has already been input, and extract coordinate information XO, YO, XI, and Yl of the same file number. As a result, if the coordinate information cannot be extracted, the process shown in Figure 22-2 is performed as in the echo mode. On the other hand, if the coordinate information can be extracted, as shown in FIG. 22-5, the right half of the working area 310 is made white, and XO, YO,
For example, the area 314A defined by l is displayed in green.

Then, the left half of the working area 310 is made white,
Within that plane, LO (...) command and ADR (...
-) Displays the area 314B defined by the coordinates x θ' and Yo' newly specified by the command in red. Also, in the right corner of both areas 314A and 314B,
Displays the file number FN of the image file.

If the new editing area created by XO', YO', XIo and Ylte exceeds the editable area, the inputs of XO' and YO' are invalidated and a new valid input is awaited. The edit image area displayed by inputting coordinate information is erased by inputting a command.
Display the command group being created again.

When the ``Trace'' key is input, the LO (...) command is selected from the command group of the program being created.
A CR with a file number equal to that file number (・
...) command, and as shown in Figure 23-6, the left side of the screen of the CRT 300 is set to white, and the areas 316A and 317A determined from the coordinate information XO, YO, XI, and Yl within that screen are set to red. and furthermore,
The file number FN of the image file is displayed in the lower right corner of the area. On the right side of the screen, for example, this is colored blue, and within that plane is an area 316B determined from the changed coordinate position information XO' and YO', x1 and Yl.
and 317Bfe are displayed in green. Further, a rightward arrow 318 is displayed in the center of the screen to indicate movement of the image.

When all image file movement displays are completed, the message area 340 displays 'END OF TRA'.
CEMODE” is displayed to notify the operator that tracing has ended.The operator then presses the console unit 20OL.
When you point to any point, the commands for the application file you are creating will be displayed again.

That is, it is possible to visually understand where the image information is moved by the application file currently being traced.

When creating an application file, as mentioned above, image file number 1 image area (XO, Y
O, Xl, YI), i Collection 4'l (7) a In addition to specifying the new position (XO', YO') and the number of prints numerically, you can create a program using them as variables, giving you flexibility in image editing. can have.

For example, the following command 11'4 can be configured as an application file that performs trimming using variables.

(1) RE (OR) The league unit 500 reads the original and stores it in the backup memory 2.
Stored in 2 (2) CR (N, 0.F) (OR) On the disk memory 90, file number N, area Fl: XO, YO, X

(S) (CR) Copy eight copies of the image information stored in the backup 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 writes "5TORE THIS C0DN" to the message area 340.
AND FILE? ” is displayed to confirm whether or not to register the application program stored in the RAM 458 in the disk memory 80 as a file.

When the operator denies this message and inputs the "°N°°" key, a negative determination is made in step 53B, and the editing station 450 exits the edit mode, erases one screen 301, and proceeds to step S37. Return to echo mode.

On the other hand, when the operator inputs the °°Y°" key to request file registration, an affirmative determination is made in step S38, and the process proceeds to step 938.
Based on the file number set in step 32, the editing station control unit 450 sends an ED(...) command to the image processing unit 10 and obtains permission to transfer the application file. If a file with the same file number as that file number is not registered on the disk memory 80, a negative determination is made in step S39 and the process proceeds to step S40, in which the image processing unit IO sends a message to the editing station control unit 450. File registration is permitted and file transfer is executed.

When the file registration is completed, the process moves to step S37 and returns to the echo mode. If a signal indicating that a file with the same file number as the created file has already been registered is transferred from the image processing unit 10 to the editing station control unit 450, the process proceeds to step S39.
If an affirmative determination is made in step S41, the message area 340 is filled with, for example, "FILE ALREA".
DY REGISTERED.

DELETE OLD? ''' is displayed to ask the operator whether or not to erase the file with the file number set to - in the disk memory 90.

If the operator agrees, the first editing station control section 450 sends D to the image processing section IO in step S42.
Send the E (...) command, then step 93
Return to 8. If the operator denies it, the process advances to step S43, and the editing station control unit 450 displays 'ENTER FILE NO, ANDCAR' in the message area 340.
"RIAGE RETURN" is displayed to prompt the operator to enter a new file number manually. When the operator enters a new file number manually, the process moves to step S38.

Note that if the response of the image processing unit 10 to the ED command is other than the error code “08°°, the 1 editing station control unit 450 determines that it is impossible to transfer the application file, erases the screen 301, and shifts to echo mode. At the same time, a corresponding error code is displayed in the message area 340.

Next, the processing procedure when there is an instruction from the application file call 17 key will be described. When the file number is input in step S32, the editing station 400 is set to command mode, and the editing '! , the L station control unit 450 outputs XR (・
...) outputs the command to the image processing section 10. Therefore,
In step S46, the image processing unit 10
Call the corresponding application file from 0 and R
Transfer to AM45B. Editing station control unit 450
When it completes receiving the application file, it sets the edit mode to 1 in step S47, then moves to step S33, and deletes and inserts lines and characters using the same procedure as in creating the application file. Modify application files. In addition,
If an error code is sent from the image processing section 10, the editing station control section 450 erases the screen of the CRT 300 and returns to echo mode, and displays the error code in the message area 340 and status display area 360, respectively. and display the error message and status corresponding to the error code.

Next, the procedure for routine business input processing will be described. The operator is
When the "°" key is pressed and the file number of a desired application file is input, the editing station control unit 450 stores the specified file in the RAM 45B, as in the case of calling an application file (steps S32 and S45). ~547).And,
In step 548, the editing station control unit 450
The command group stored in AM458 is searched from the beginning to find variables N, F, P, and S. Step S49
If, as a result of the search, those variables are not found, the process moves to step S53, and the command group of the application file is transferred one by one to the image processing unit 10. On the other hand, if it is determined that there is a variable, the process advances to step S50.

In step S50, the editing station control unit 45
0 first discovers the variable N, displays a comment in the message area 340 of the CRT 300 asking for the input of a file number, and then converts the variable N into a numerical value entered manually by the operator. Next, when the variable F is found, a message area 340 is displayed asking you to specify an image area, and the variable
Replace with Next, when the variable P is found, a message area 340 is displayed asking you to specify the image position, and the variable P is replaced with the values XO' and YO' input by the operator, and the position specification input is changed to CR (・・) and LO(・
...) command, the process shown in FIG. 23-5 is performed, and if it is related only to the LO(...) command, the process shown in FIG. 23-2 is performed. Also, when the variable S is discovered, the message area 340
is displayed asking you to enter the desired number of copies, and the variable S is set to 1? to the number entered by the operator. ′jConvert.

In this way, when the operator replaces all the variables in the command group with numbers (iri), the process proceeds to step S51, and the editing station control unit 450 performs the tracing process as shown in Figure 23-6 to process the editing form. Area 310
,,I:, and then in step S52, "°OK9"° is displayed in the mensage area 340 to confirm with the operator whether the form of the first image box is as desired.

If the operator denies the confirmation by instructing the "N" key, for example, the editing station control unit 450
erases the screen of the CRT 300 and moves to step S37. On the other hand, if the operator affirms this, for example by pressing the °゛Y゛Y゛ key, the process moves to step S53, and the editing station control unit 450 saves the screen as it is,
The command sequence is sequentially transferred to the image processing unit 10 to execute a predetermined program.

The image processing unit 10 echo-packs the transmitted command character to the f1MN station control unit 450, and the editing station control unit 450 displays the command in the status display area 360 so that the operator can recognize the status of the tree system. let

The editing station control unit 450 controls the image processing unit 10 to
After executing the l command, 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 10, the editing station control unit 450 interrupts the command transmission, erases the screen of the CRT 300, displays an error code in the message area 340, and sends an echo. Move to mode.

In addition, in the processing in the above-mentioned edit mode, that is, in the processing of command file creation, command file calling, and routine work, if the operator instructs the edit reset key during the input processing in step S33 or step S50, The screen of the GRT 300 is immediately erased, and the process moves to step S37 to return to the echo mode.

Further, if there is an end input, a KL command is output to the image processing section 10, the online state between the image processing section 10 and the editing station 400 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 on- and off-campus communication and image editing using application files. As mentioned above (123), the league section 500 is in copy mode and nib-in 1-

Effects As explained above, according to the image processing apparatus of the present invention, the following effects can be obtained.

(1) A league unit that reads manuscript images; an image processing control unit that controls image processing and stores processed images;
An editing station that edits image information; an optical fiber interface that communicates image information between this system and other systems on the optical fiber network; and an optical fiber interface that communicates image information between this system and other systems on the DT) X line network. Since the image processing apparatus of the present invention is constituted by a DDX interface for mutually communicating image information between the two, and a printer section for copying image information, it is possible to read image information, process image information such as image editing, and use an optical fiber network. Short-distance communication of image information using a DDX line, long-distance communication of image information using a DDX line, and copying of image information can be easily and quickly performed at low cost.

(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. By switching the flow of the image information being sent to the buffer memory, optical fiber interface, and printer section, it is now possible to select one or more of them and transfer it to each section, making it possible to read, short-distance communication, and copy image information. Processing can be performed in parallel, and image processing time can be shortened.

(3) Image information transferred from other systems on the DDX line network via the DDX line network and DDK interface is stored in the buffer memory, so the processing of the image information stored in the buffer memory is explained above. The same effect as product (2) can be obtained.

(4) When communicating image information between this system and other systems via the DIIX line network, an image of a predetermined size of a document is sent between one system and the other system within a predetermined time. Signal R indicating that information can be transmitted
DS and a signal RDR indicating that it can be received are sent to each other, and in both systems, the RDS of both systems is
Since the transmission direction of image information is determined from a certain combination of and RDI'i, errors in the transmission direction can be prevented and the time for transmitting image information using the DDK line can be shortened. can.

(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 one line of image information using a two-dimensional encoding method. When 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 2560, 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, and data compression can be performed efficiently. Since this can be done frequently, the transmission time can be shortened.

(6)I]I]x When communicating image information between this system and another system via the line network, the image processing control unit sends a signal to the DDX interface requesting connection to the other system. CRQP, a signal CNQ requesting acquisition of the DDX line, a signal NRYP indicating that the image processing control unit cannot be in a state where image information can be transmitted or received within a predetermined time, and a signal CNQ requesting capture of the DDX line. Signals RDS and RDR that respectively indicate that it is possible to be in a state where it can transmit and receive, and image entertainment p for 1 life.
A signal RQS indicating the valid period for supplying the image data to the DDX interface and image information IfgsDT are transferred. Also,
The DDX interface sends to the image processing control unit a signal CIP indicating that a call has arrived from another system, a signal NRYII indicating that the DIIX cotton pad cannot be connected, and DD.
A signal CND indicating that the X line connection has been completed and communication is possible, and a signal MDS indicating that the DDX interface is in a mode where image information can be sent to other systems.
, DR to signal 46 indicating that the mode is set to receive image information from other systems, signal RQS requesting transfer of 1 line of image information, and 1 signal received by the DDX interface from other systems and demodulated. A signal RVA requesting reception of image information for a line and image information received and demodulated from another system are transferred. These signal groups enable reliable communication of image information between this system and other systems.

(7) When communicating image information via a DDX line, once the relationship between the calling system and the called system is determined between the tree system and the other system, both systems can communicate with each other. When the transmission conditions of both systems are established, they mutually send a transmission preparation completion signal, the calling system starts transmitting image information for each line, and the called system starts transmitting. Transmission errors are monitored for each line received. 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 in which the transmission error occurred, and then two-dimensionally encodes the following line. Resume transmission. 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 optical signals transmitted serially from other systems on the optical fiber network into electrical signals, and reproduces image recording commands and image information from the signals to perform image processing. supply to the control section,
In addition, commands and image information related to image recording for other systems transferred from the image processing control unit are converted into optical signals and output to the optical fiber network, so that the system that records one image can easily operate the commands and image information. Image information can be recorded without requiring , and image processing can be speeded up.

(9) The image processing unit (CPU 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 precipiter unit. Sends a recording preparation command according to the status, and
Since the printer section records image information in response to the command, it is possible to record images directly from the image processing information forming unit while recognizing the status of the printer section. can be done effectively.

(10) The image processing control unit includes a disk memory,
The disk memory can store image files, application files, and control programs for the image processing control unit, so a large amount of image information can be stored and
Editing etc. can be easily performed.

(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. , it is possible to command the reading of the original image directly from the image processing information forming unit side,
Thereby, images can be read efficiently.

(12) The league section is equipped with a league operation section, and the application file stored in the Dinuk memory can be started from the league operation section, so that the league section can easily carry out the routine work of image editing.

(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
Image 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 coordinates of the image to be edited are input, 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 manually created information, you can quickly deal with it. It can be done efficiently.

(lf3) A command to start the league section is provided in the command menu section of the W collection station, and by inputting that command, it is possible to have the league section perform the operation of reading the manuscript image. When it is necessary to cause the league section to perform a reading operation, the operation can be executed simply by operating the command menu section, thereby simplifying the image editing work.

(17) Since the command menu section has a command that allows you to select a dither pattern, you can make such a selection simply 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.

(19) The command menu section includes a command to start the printer section, and by inputting that command, the printer section can be made to perform image recording operations, so it is possible to cause the printer section to perform recording operations during image editing work. In cases where execution is necessary, the same effect as the superposition (16) 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.

(2I) Since the area on the digitizer is made to correspond to the 7 traces in the buffer memory, image editing can be performed easily and without error.

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

(23) When editing images, etc., if the image editing area specified by the editing station exceeds the editable area of the device, a warning is displayed on the CRT screen, so image editing can be performed reliably. I can do it.

(24) When editing an image, an identification number is attached to each editing area, and the area is displayed as a frame on the CRT screen, and the identification number is displayed within the frame. Therefore, the operator can visually confirm the editing area, and therefore can easily and reliably perform image editing.

(25) Since the execution form of the editing program can be traced on the CRTR7 screen, the execution form can be visually checked, and therefore not only the operator who created the editing program but also other operators can perform image editing. This can be done easily and reliably.

(26) When creating an editing program, the number of recorded images, editing area, etc. can be manually set as variables, so the system can be made flexible, making image editing easier. can be done.
