Description

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

BACKGROUND OF THE INVENTION Conventionally, as image processing apparatuses, copying apparatuses as means for copying original images, facsimile apparatuses as means for transmitting original images to remote locations, and the like have been widely used. When copying a document, general copying apparatuses currently in use can copy an image of the same size as the document, or perform enlarged copy or reduced copy. Alternatively, if it is necessary to change the image density, the density can be changed uniformly over the entire copied 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, process the image information converted into an electrical signal, extract a part of the document, and copy it, or combine multiple images, or +i!, such as changing the image density of only a part of the image. 11. Copying devices with image editing capabilities have been proposed. However, as a copying apparatus is provided with many such functions, the apparatus becomes more complex, resulting in a problem that the copying operation becomes complicated and the image processing time becomes longer.

On the other hand, with facsimile, it is possible to simply send an original image to a remote location using a telephone line, and if it is necessary to make copies along with sending the original, an appropriate copying device is required in addition to the facsimile machine. There are some issues that need to be addressed. Furthermore, since facsimile machines do not have an editing function, if you want to send a manuscript image after editing it, a human must edit the manuscript image, which requires a lot of effort and time. There is a problem with wastage. Furthermore, facsimile machines use telephone lines when transmitting original images to other parts of the premises, such as factories and offices, using so-called short-distance communication, 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 that can easily and quickly perform image processing such as image editing, and short-distance and long-distance communication of image information at a low cost.

The address/data buffer block 80-4 includes two address/data buffers, each having a signal line 80-4.
It is coupled to multipath 60 and internal path 80-5 via buses 115 and 80-116, and receives and passes address information and data information to and from these buses.

Determines whether or not the multipath 30 enters the wait state and releases the wait state, and outputs a bus ready signal to the I10 processor 80-1 via the signal line 80-123 based on the determination signal. .

The synchronization signal generation circuit 80-7 generates a signal for confirming the response of the ROM 80-8 using the above-mentioned l0RC signal and INTA signal and a chip selection signal supplied from the address decoder 5o-io via the signal line 80-125. By generating this signal and supplying this signal to the clock generator 80-6 via the signal line 80-126, the I10 processor 80-1 can proceed to the next operation.

The operation of receiving and passing address information and data information to and from the internal bus 80-5 will be explained below. First of all, is the multipath 60 and its information received and delivered? One case will be described. I10 processor 80-1 address/data (when outputting the sofa 80-41 neighbor address, ALE 4 words are supplied to the pass control draw 780-3 force e address/data notebook y 80-4) , address/data (sofa 80-4 will send the address information to the address/data page 2, and after lunch)
0, the bus arbiter 80-2 supplies the AEN signal to the address/data buffer 80-4, and the address/data buffer 80-4 transfers the latched address information to the multi-node 60. Output to.

Here, if the DMA controller 80 is in write mode and the multipath 60 has been acquired, the I10 processor 80-1 outputs data information to the address/data buffer 180-4, and 80-4 is the path controller 80-3 to DEN
Upon receiving the signal, it outputs data information to multipath 60. In contrast, when DMA controller 80 is in read mode, address/data buffer 80-4 reads the data information on multipath 60 and provides the data information stream to I10 processor 80-1.
The reading of data information by the processor 80-1 is as follows:
Check the XACK signal sent from the disk memory 90, which is the data transfer destination, to the I10 processor 80-1 (-0). will be carried out.

7 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 80-2 is not required. In addition, the data information is transferred to the internal path 80-5.
Whether or not to output the signal to the bus controller 80-3 is determined by the PDEN signal from the bus controller 80-3.

As the disk memory 90, for example, WDS-10 of Sword Computer is used. The disk memory 90 has an internal disk controller circuit (not shown), and this circuit is connected to the internal bus 80-5 of the DMA controller 80 via a data bus 80-140.

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 0 and 0.

Note that a set of information consisting of command information, result information, and data information and status information differ in the timing at which the data becomes ready, and also differ in read mode and write mode. The generation circuit 80-7 receives the I signal transmitted via the signal line 80-112.

(3, 4) Multipath Memory Space FIG. 8 is a memory map of the CPU circuit block 10, buffer memory circuit block 20, and DMA controller 80 related to the multipath 60. The multipath 60 has a 1 megabyte address space from 0OOOOOH to FFFFFH as a memory mapped memory space. This space is divided as shown in Figure 8, and addresses FCOOOH-FFFFFH are used as the program memory space of the CPU 10-1 of CPU circuit processor 7 and 10, and addresses 10000H and 06000H are used as the buffer memory bank space (described later).
~07FFFH address cPU circuit block 10 and DMA
A program space for communication with the controller 8o and addresses 0OOOOH-05FFFH are assigned to the work RAM space of the CPU circuit block 1o. Here, each address space will be explained.

The program memory space includes a RAM 10-3 that stores a control program for the device of the present invention in the CPU circuit block 1°.
memory space.

The buffer memory puncture space is from address 100OOH to E.
It has a capacity of 896 kilobytes up to address FFFFH, but as mentioned above, the storage capacity of the buffer memory circuit block 2° is 1.995840 bytes, and it is not possible to store all of it in the punctured space of the buffer memory.

Therefore, the Panzer memory space is divided into three banks, namely:
Bank 0. It is divided into bank 1 and bank 2, and the signal line 132 (FIGS. 4 and 6) is connected to the CPU circuit block 1o.
The banks are switched by the puncture switching signal outputted through the 8th block (see FIG. 2), and the designated bank is allocated to the memory map as shown in FIG. This division and allocation process will be described in the explanation of FIGS. 9-1 and 9-2.

The communication program space uses 8 gigabytes of the RAM (32 kilobytes) 10-3 in the CPU circuit block 1°. In addition, the work RAM space is
32 kilobyte key 10- in CPU circuit block 1o
Use 24 kilobytes, which is obtained by subtracting 8 kilobytes used for the communication program from 6.

FIG. 9-1 shows an address map of the buffer memory 22 in the buffer memory circuit block 2o.

This buffer memory 22 is A4 size (297mm x 2
It has the ability to store information decomposed into 16 pixels per 1 mm from a 10 mm original. The reader section 500 main scans the A4 size document in the vertical direction (297 m direction), and then the CCDs 570, 580, and 590 scan the A4 size document at 1 per page.
The image is divided into 6 pixels and 4752 bits of pixels are supplied to the image processing control section 100 per scan. Also, League Division 50
0 sub-scans the document in the width direction (21mm direction), and C
CD 570, 580 and 590 also have 1 in this direction
Since 16 lines are scanned per u, the document has 3 lines in the width direction.
360 lines are scanned. Therefore, an A4 size document is decomposed into 1,596,6720-bit pixels, and the image processing control unit 100 stores 4,752-bit pixels in series.
Supplied 360 times.

The procedure for assigning addresses to the image information supplied in this way and storing them 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, and each block is composed of 62,370 blocks.

In one unit block, there are 16 lines of 16 bits, that is, 256 bits of image information.
If 6 bits are one word and one address is given to one word, one unit block will be composed of a group of pixels having 16 addresses. 47 for the first line, that is, one line of the original to be scanned first
The 52-bit serial image information is divided into pixel groups of 16 bits each corresponding to one vertical interval of the document and supplied to the image processing control unit 100, and the first 16-focus pixel group transferred is Address 0OOOOH of buffer memory 22,
The next 16-bit pixel group is at address 0OOIOH, and in the same way, pixel groups of 16 bits each are sequentially addressed to 16 (
IOH) address 00020H, ooo3ou
Addresses are stored like address 01280H.

The addressing of each line to the buffer memory 22 is determined by the CPU circuit block 10 using an address counter 21-6.
This is done by setting the initial value to .

Also, the image information is transferred from the buffer memory 22 to the printer section 6.
When outputting to 00, as in the case of storing image information, it is read every 16 addresses from the initialized address.

Next, the 4752-bit image information for the second line is processed from address 000IH to 01 in the same way as for the first line.
It is stored up to address 281H. In this way, 1536 lines (96u in the width direction) from the first line to the 1536th line are stored from address 0OOOOH to address 6F5FFH, and this address space is designated as bank 0 on the buffer memory 22.

Next, 1 from the 1537th line to the 3072nd line
The 536th line is stored in addresses 70000H to DF5FFH in the same manner as Punk 0, and this address space is designated as Punk 1 on the buffer memory 22. Furthermore, the 307th
E for 288 lines from 3rd line to 3360th line
Store from address OOOOH to address F'4EIFH,
This address space is designated as bank 2 on the buffer memory 22.

If you use the method of assigning one address to one word of image information and storing it as shown below, you can store an A4-sized image at consecutive addresses on the buffer memory 22 using an I MX I M square as a unit block. This means that the entire area of the original can be stored. As a result, when an operator specifies an image processing area in units of friends using the console unit 200, when registering the specified area in the disk memory 9G, DMA transfer can be performed by simply setting the start address and end address of the specified area. The image information can be transferred at high speed without going through the CPU circuit block 10.

That is, by specifying a set of the first address and the last address, the image information of the main scanning line (1 m width) is transferred to the DMA.
Since the data is transferred, fewer address settings are required during DMA transfer, and the transfer speed can be increased.

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 whose length in the vertical direction is 20M, the address setting by CPU circuit block 1° is 20M.
It will only take a few times.

Further, since the address is in the middle and corresponds to the position on the original image, when editing one image, the operator only has to specify the position of the original -F on a frame-by-frame basis, which is convenient. In this example, since CCDs 570, 580 and 590 having a reading capacity of 16 bits per wn were used, it was decided that one address corresponds to 16 pinpoints in the vertical direction, but the number of pits corresponding to one address is , the CCD
Depending on the capabilities of 570, 580 and 590, the same numerical values may be used, and the same effect can of course be obtained even if the address is set in units other than U, such as inches.

Figure 9-2 shows the flow from the multipath 60 to the sofa memory 2.
The address map when looking at 2 is shown. 0 in Figure 9-1
The address space from 0.70000H to DF5F'FH is set as 0.70000H to DF5F'FH, and the address space from 0.70000H to DF5F'FH is set to 2. Address C2100OOH~EEBFEH, 1000 as shown in the diagram
Address 0H~EEBFEH, 100OOH~39C3EH
Correspond to the address space of the address. Multipath 60 is 1
It has a 6-bit data bus and a 20-bit address bus, but the area that can be accessed by this martennobus is 1 megabyte. In other words, 106 pieces of 8-bit data can be accessed; When accessing data, it will span two addresses, so in this case, as shown in Figure 9-2, consecutive addresses are assigned every other address for 16-bit data, and even-numbered addresses are accessed. Only when this happens, 16 bits of data will be output.

Since the actual address in the panzer 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. 9-2 is converted to the address in FIG. 9-1 by the address converter 21-26 in the panzer memory circuit block 20, as described above. do. These address converters 21-26 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 90. 91 is a drive, numbered 0, 1, . . . corresponding to the number of disk devices. ...and number it. In this embodiment, only one disk device, that is, the number 0 drive is used. The drive 91 has three heads 92, and each head 92 has 354 tracks 9.
Each trunk 93 consists of 18 sectors 94, and each sector 94 can store 512 bytes of data. Therefore, the storage capacity of the disk memory 90 is approximately 10
It is a megabyte.

Sequence number SN, head number HN, and trunk number T
There is a relationship between N and the following equation (1).

SN=3 X TN+HN (However, HN=0~2
．． TN-0 to 353) (1) In other words, when a certain sequence number SN is determined, the corresponding trunk number T
N and the head number HN are determined, and the address of the head 92 and track 9B to be accessed next is the sequence number S, which is the previously determined sequence number SN plus 1.
These are the head number and track number obtained corresponding to N+1. Sectors 94 within track 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 90, and the use status of the disk memory 90 is managed by this index table. In this embodiment, the area is the sector 94 with the rack number TN=0,
Sectors with sector numbers 5CTN = Q to 13 are used as an index table area, and sectors with sector numbers 5CTN = O to 8 are used as a sector bit map table 94A showing the usage status of each sector on the disk memory 90. and sector number 5CTN.
= Sectors 9 to 13 are allocated to the file index table for file management. Sector number 5CTN=O~
The 13th sector is a program (which is an index table) to be read into the RAM 10-3 in the CPU circuit block 10.
Open program) writes to the fixed area from address 6000H to address 7BFFH of RAM10-3, receives a predetermined operation, and then writes the fixed area of RAM10-3 to 1.
The program stored in the disk memory 90 (close program) is written to the disk memory 90 again.

As shown in Figure 10-3, the sector bit map table divides the area 94A into 1062 blocks of 4 bytes each from 5N=O to 5N=1061 in the order of sequence numbers SN, Block (-1
Data indicating the usage status of the trunk, that is, 18 sectors, is stored by allocating one column per sector. As data showing the usage status of the sector, if it collapses,
If a certain sector is in use, f "1" is stored in the sector bit corresponding to that sector; if it is unused, "0" is stored.

When registering a new data file in the disk memory 90, find a continuous empty area of the number of sectors necessary for the registration, obtain the sequence number SN and sector number 5CTN corresponding to that area, The sector bits (2'1'') corresponding to that sector are stored. Conversely, when erasing a data file, the sector bits (2'0's) indicating the corresponding area are stored. However, the index table ( "1°' is stored in advance in the two-pair window bit, that is, block O, and writing to this block OC2 is prohibited. 1. No data file is registered in the index table. Let's do C2.

The file index table is stored in disk memory 90.

The management status of these files using the file index table is shown in Figure 10-4 (2).

The file index block FIT 1) consists of four blocks of 2 bytes each, with status A, MAX block, 1 block size, and number B, and is provided when the disk memory 90 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 of four files that can be registered in the disk memory 90, and in this embodiment, the total number is set to 50 (32H). ]Block size is 1
This indicates the length of the index of various data related to each file, and in this embodiment, the length is 38 (26H) bytes as described below. Current B
The number stores the number of files registered in the disk memory 90, and when one file is newly registered, M
Compared to the number stored in AX size, if the number does not exceed that number, 1 is added and a new registration is performed, and if it exceeds the number of MAX size, it is not added and a new registration is performed. Make it unacceptable. Conversely, when deleting one file that has already been registered, the number stored in the current B number is decremented by 1, and the file is deleted from the disk memory 90.

FIT 2 and FIT 6 indicate file index blocks for file type 0 and file type 2, respectively, and each stores 38 bytes of data. In FIT 2 and FIT 3, R8V is a 2-byte area used for system expansion, and is unused in this embodiment.

The file number can be set arbitrarily by the operator from 1 to 99.
This is a 2-byte area that identifies the file number when it is registered in the disk memo J'90 with a number up to . The file type is the file type “0” mentioned above.
Alternatively, it is a 2-byte area in which data "2" is written. Puncture and address in FIT 3 are CP

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

Sequence No., Drive No., Head No.) Rack No. and Sector N are the sequence number and drive number of the beginning of the storage area for the registered file.

This is a 2-byte area each for storing a head number, track number, and sector number. XO, Y in FIT 2
O, XI, and Yl are 2-byte areas each, and in the case of file type "0°", C2 contains coordinate data indicating where on the copy paper the image information of the area to be edited is placed. Remember: XO, YO, XI and Yl are

and point B farthest from the 0 point using the stylus pen 280.
The coordinates XO and YO of point A and the vertical length Xl and horizontal length Yl of the editing area are determined by the instruction using , and these values are stored in hexadecimal. For file type 2, use FIT as shown in FIT 3.
The areas corresponding to XO, YO, Xi and Yl of No. 2 are unused areas.

When transferring a certain image data file from the disk memory 90 to the buffer memory 20, first, specify the file number, and then the index table is transferred to the RAM1Q-3m by the open program to obtain the index block of the specified file number. Next, the address on the sofa memory 22 is calculated from the data stored in XO, YO, DMA transfer is performed to.

Also, when changing the position of the editing area on the copy paper,
Since Xl and Yl remain unchanged, only XO and YO can be used as parameters, and only XO and YO can be changed by an image position change command (described later) from the console unit 200.

In addition, the disk memory 90 stores the control program of this system, and the file is set as [file type].
Its file index block is configured similarly to FIT 3.

This system converts image information into MH and MH encoding.1. The method of transmitting it to other systems is COI
Based on the T.4 recommendation of the TT, the following points should be considered when applying the T.4 recommendation to the present invention.

(1) With the device of the present invention, the vertical direction (2
97 direction) as one line, and the degree of plowing is 16 pisoto/
M, the maximum run length, that is, the run length when one line is all white or all black is 4.
752, which exceeds the maximum expression range of 2623 (=2560+63) of the extended MH code.

(2) In the device of the present invention, the parameter K is set to infinity.
Transmission is performed using a dimensional encoding method. 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 3359 lines are MR encoded.

Regarding point (1), the reason why the length direction is set as one line is as follows. In other words, (1) reducing the number of transmission lines to shorten the transmission time; and (
it)! By reducing the overall movement distance of the sensor in the sub-scanning direction in the J-reader section 500, the reader section 50
We aim to downsize the 0.

Regarding point (2), setting the parameter K to infinity means setting the parameter K to a small finite value and setting it to K l
This is to save the time of repeating MH encoding for each i'il, and the reason why the parameter K can be set to infinity is that the image information to be transmitted has already been binarized by the COD driver 50, and once stored in the buffer memory 22. This is because the meaning of reducing the reading error by setting the parameter K to a small finite value is lost.

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

First, one line of image information (4752 bits) transferred from the buffer memory 22 via the signal line 167 is transferred to the line buffer 60 via the data/clock interface 60-1 and the write switch 60-6. −
4.6CI-5 or 60-6. This image information is transferred to line buffer 60-4, 60-5 or 6°-6 at a transfer rate of 1 bit per 0.1 microsecond (μS) in synchronization with a 10 megahertz (MHz) clock signal. Ru. That is, the transfer time for one line of image information is 475.2 μs. The image information of the first line that is transferred first is first supplied to the line buffer 6o-4 by the switch 6o-3, and when the line buffer 60-4 finishes storing the image information of the first line, The switch 60-7 opens the gate of the line buffer 60-4, closes the gates of the line buffers 6o-5 and 60-6, and transfers the stored image information to the RL converter 60-.
The first line of image information for which the white and black run lengths have been counted and run length encoded is supplied to the RLeMH/MR converter 6.
0-10 Ni! ,,l Converted to MH code. While the line buffer 6o-4 is outputting image information, the switch 6o-3 switches between the line buffers 60-4 and 6o-4.
Close the gate to the line buffer 60-5, open the gate to the line buffer 60-5, and transfer the image information of the second line to the line buffer 60-5.
Supply to 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 positions are counted and Mm encoded by RLMMH/MR converter 60-10.

The image information of the 3'th line transferred to the line buffer 60-6 is also processed in the same way as the 2'th line. The image information output from 5 and 60-6 is sent to the RL forward/reverse counter 60-7.
The signal is then supplied to the RLMMH/MR' converter 60-10, where it is MR encoded.

Next, the running coded image information supplied to the RL4+MH/MR converter 60-10 is MH coded or MR coded and compressed.

As described above, in the device of the present invention, the maximum run length is 4752, which exceeds the maximum expression range of 2623 for the expanded MH code, so the MH code is further expanded by the following method.

(1) Run length RL〈256o normal M
It is represented by II code. That is, in the case of RL (64), it is represented by one terminating code.

64≦RL (2560 is represented by one make-up code and one terminating code.

(2) 2560 when run length RL≧2560
The make-up code ゛0000000111bi is regarded as a special code and handled as shown in (a) and (b) below.

(a) 2560≦RL≦2623 =2560 +
, 63 As in case (1), one make-up code (in this case, 2560 make-up codes)
and one terminating code.

(b) 2623 (If RL≦4752, following the make-up code of 2560, add one more make-up code as needed, and then add one terminating code. That is, (2 ), the 256o make-up code is immediately followed by a terminating code of the same color (a), and the 256o make-up code is followed by a make-up code of the same color, followed by a terminating code. There is a case (b).A processing example for case (2) is shown below.The underlined numerical values are the added makeup codes.

Example + 2560=2560-1-0 2561, =2560+1 2623=2560+63 2624=2560+6440 4289=2560+1728+1 4752=2560+2176+16 Next, in Figure 11 (A), (B) and (C), and Figure 12-1 The meaning of each signal flowing along the signal line interconnecting the illustrated image processing unit 10 and the DDX interface 60 will be explained.

FIG. 12-2 shows each signal, its name, and the direction (arrow) of the signal between the image processing unit 10 and the DDX interface 60.
FIG. Here, FG and SG are a safety ground line and a signal ground line, respectively.

The image processing unit 10 receives the call request signal (CRQP) from the DD.
This signal requests the X interface 60 to connect (call) with another system, and this signal is a connection raw signal (C
ND) is deactivated at the same time as it is activated, and when the connection failure signal (NRYD) is activated, it is treated as invalid. The call signal (CIP) is a signal indicating that the DDX interface 60 has received a call from another system to the image processing unit 1o, and the processing for CND and NRYD is the same as CRQP.

The dial number signal (DLN, ) is activated 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 that the image processing unit 1o requests the DDX interface 6o to connect to the DDX line, and is activated at the same time as either CRQP or CIP is activated, and NRYD is activated. It is considered invalid when the Also, while it is necessary to seize the line, CN
Q is energized, and deactivating CNQ will disconnect the line.

The non-receivable signal (NRYP) is activated when the image processing unit 1o cannot be in a state where it can transmit or receive within 6 seconds. NRYD indicates that the line cannot be connected when the DDX line 800 is in a busy state or when the non-treasury inch of the NCU 802 is activated. This NRYD line is always activated or deactivated depending on whether the line connection is disabled or enabled, respectively. Further, if CND is not activated even after a certain period of time has passed after CRQP is activated, the image processing unit 10 determines that connection is not possible.

-CND is activated when the communication conditions between this system and the other communication partner system (partner station) are established by activation of CRQP or CIP and activation of CNQ, and the line connection is completed; Indicates that this system is ready for communication. CND is deactivated when CNQ is deactivated or when the other station disconnects the line. Clear 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-sized document within 6 seconds, respectively, and indicate that the CNQ activation and At the same time, RDS or RDR is activated.

Transmit mode signal (MDS) and receive mode signal (MR
R) indicates that the system is set to a mode of transmitting and receiving image information, respectively; these modes are determined by looking at the RDS and RDR of both the calling and called parties. Immediately after transmission or reception is completed, 1. It can also be received or sent.

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 activated and deactivated at regular intervals, and the DDX interface 60 requests the image processing section 10 to transfer one line of image information.

When RQS is activated, the image processing unit 10 activates the transmission data valid signal (SVA), and sends one line of image information (SVA) from the breadth memory 20 to the DDX interface 60.
DT) is transferred. RQS is deactivated upon completion of the transfer. The RQS repetition period is set longer than the minimum transmission time. SVA is activated in response to RQS, indicating permission to sample SDT' in synchronization with the transmit clock (SCK), and activated upon completion of SDT transfer. The RVA is energized at regular intervals, and the DDX interface 6o requests to receive one line of expanded image information +'l1 (RDT) received from another system.
Indicates that RDT is allowed to be sampled in synchronization with the reception clock (RCK). The repetition period of RVA is similar to RQS.

SDT and RDT are binary transmitted and received image information such as black and white, SCK and RC, respectively.
K are 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). The called station) compares the RDS and RDR and makes a decision as shown in Figure f12-3, thereby preventing errors in the transmission direction.

That is, in Figure 12-6, as shown by the energized state ○, the transmission direction by arrows, and the deenergized state and transmission disabled state by trees, only the RDR on the calling side and at least the RDS on the called side are shown. is activated and the calling party's RDR
When only the RDS and the RDS on the called side are activated, the transmission direction is from the called side to the calling side. Also, when only the RDS on the calling side and at least the RDR on the called side are activated, and when the RDS on the calling side is activated,
When the DS and RDR and at least the RDR on the called side are activated, the transmission direction is from the calling side to the called side. Transmission is disabled for combinations of RDS and RDR of both the calling and called stations that are not binary.

! Figure 12-4 shows an example of a procedure for performing transmission between a calling station and a called station. Here, I
DS is a transmission capability identification signal, which is a signal that mutually informs the transmission capabilities of the calling and called stations, ie, RDS and RDR. The transmission fo, -
As a mat, for example, OOOORDS RDR10
” will be sent sequentially from the most significant bit to the least significant bit, and both stations will be connected to the R of this system.
1. The transmission direction is determined from the DS and RDR and the RDS and RDR of the other station as shown in FIG. 12-3.

RDY is a transmission preparation completion signal, and its transmission format is, for example, "00010010", which is sent in the same way as IDS. Indicates that preparations for sending and receiving image information are complete.

MHI is MH encoded first line image information, MB
2 to MRn+1 (1≦n≦3360) are MR encoded image information of the 2nd to n+1th lines, MHn is MH encoded image information of the nth line, and MRn+1
~MR3360 is MR encoded n+1th to 336th
0 line image information, MHI~Mi336o,
-i Displays one image information i for one A4 size document.

RTQ is a retransmission request signal, and if there is an error in one line of received 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 written into the buffer memory 22 of the called station, but the called station issues a self-transmission request to the calling station.

RTC is a transmission end signal, and the calling station
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 frame.

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

After connection is established, the calling and called stations begin transporting IDSs to each other, repeating the transport at least three times until they are fully prepared 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 FIG. 12-6), and both stations send DCN to phase 4J and disconnect the line. When their own stations are ready, both stations send RDY at least three times until both stations are ready, and when both stations have finished preparing and RDY has been sent from both stations, that is, at time B, both stations transmit RDY. The calling 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 size document, for example, if a transmission error occurs in the image information of the nth line at time E, the called station will issue an RTQ to the calling station. In response to this, the calling station performs MH encoding on the image information of the n-th line, sequentially MR-encodes and transmits the (n+1)th line to the 3360th line.

When the transmission of image information is completed in this way, the calling station sends an RTC to the calling station, and then both stations send IDS to each other, and at this time, the transmission conditions are set as shown in Figure 12-6. If the above is satisfied, other image information is subsequently transmitted and received from time point C. Conversely, if the condition is not met, they mutually send DCN and disconnect the line.

(6) Image editing method (Elephant editing uses buffer memory 22 and disk memory 90)
DMA transfer is appropriately performed between the host and the host.

That is, image information for one A4 size original read by the reader unit 500 is stored at a predetermined address in the buffer memory 20, and a part of the image information is 1) transferred to the disk memory 90 via the MA controller 80; Store in. Therefore, the buffer memory 22 is erased, the image information previously stored in the disk memory 90 is restored to the desired address space of the buffer memory 22, and the image data is copied by the printer section 600, thereby creating the original. A duplicate can be obtained with unnecessary parts trimmed.

Image editing such as changing the image position and trimming is performed according to an image processing program created based on commands (described later) input from the command menu section 220 shown in Figure 6-2. Such an image processing program can be stored in the disk memory 90, and the stored image processing program is defined as an application file.

In addition, the image (number information) stored in the disk memory 90 is defined as an image file. When registering these files in the disk memory 90, as described above, the file has a two-digit file name. It assigns a file number and indicates whether the file can be deleted.

16(A>, (B) and (C) show an example of simple image editing. First, the first document L1 shown in FIG. 16(A) is read by the reader unit 500, and its image information is are stored in the buffer memory 22. Points A and B are specified using the document placement section 240 and the stylus pen 280, and
The image information within the range of Ml is extracted from the stored image information, and the file number "0" is added to the image information M1, for example.
1' is added and registered in the disk memory 90. Similarly, for the second document L2, image information M2 is extracted by specifying point C and point 0, as shown in FIG.
, with the file number “'02” added to the disk memory 9.
Register to 0. Next, the buffer memory 22 is completely erased, and points E and F are designated as shown in FIG. 1mi within M2
The image information is transferred to address spaces corresponding to areas N1 and N2 of buffer memory 22, respectively. In other words, Ba.

The image information for one A4 size document is stored in the Noah memory 22, with image information N1 and N2 arranged as shown in FIG. 16(C).

The contents of the buffer memory 22 are transferred to the printer section 600 and copied to obtain a desired edited image L3.

(6,1) Meaning of command Editing commands used when editing a single image will be explained.

The editing command is executed by the console section 20 as shown in FIG.
The image processing unit (CPU circuit block) 10 edits the image based on the editing command. Here, C is a command in the block of the command key group 222 in FIG. 6-2, and is input by pressing the desired command key 222 or the alpha vent key group 223, and the Image processing can be performed. P is a parameter and specifies coordinates and the like. The input procedure for parameter P is as follows:
This is done by opening the parentheses after pressing the command key, entering the parameters, and then closing the parentheses. Several types of parameters can be entered as necessary depending on the correspondence with the command, and the "," key is pressed between each parameter to distinguish between them. (CR) is a carriage return, which indicates that the key 225 in FIG. 3-2 is pressed at the end of inputting one editing command. 1 image processing section 1

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

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 601 that can display 40 horizontal characters and 24 vertical lines. 22nd
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 section 10 to the editing station 400.

620 on the 20th line is a blank area, and no display is made in this area, making the boundaries between the working area 610 and the following areas clear to the operator.

630 on the 21st line is a mode display area, which displays in which mode (described later) the operator is using the editing station 400. 640 on the 22nd line is a message area in which the editing station control unit 450 displays commands and parameters to be input next, error codes, etc. to the operator.

650 on the 23rd line is a user name Canilia, 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 where the status of the image processing section 10 is displayed and notified to the operator.

As other initialization, when a command is input, the echo-packed command from the image processing unit 10 is displayed in the working area 310, the carriage 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 19th line, the working area 610 is scrolled line by line. 310 (2).

The editing station 400 processes the image 1' and the processing control unit 100.
When the user is not online, the screen 601 in FIG.
“UEST” is the message that accepts the key “NOT”.
READY, ENTER REQUEST KEY
” and waits for input of the “REQUEST” key in step S2.

The editing station 400 can be roughly divided into two modes: t
That is, it operates in echo mode and edit mode. In the echo mode, characters input by the operator via the console section 200 are transferred as they are to the image processing section 10, and are also transferred from the image processing section 10 to the editing station 400.
In this mode, the characters transferred to the CRT 30G are displayed as they are on the CRT 30G.

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, the RAM 456 in the editing station control unit 450
The image data is temporarily stored in the CRT 300-1 and then transferred to the image processing section 10 after being arbitrarily modified by the operator using the CRT 300-1. 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 the echo mode is determined as a result, the process proceeds to step SB, where the echo-punctured character from the image processing unit 10 is displayed in the working area 310, and the process proceeds to step SG. Then, 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 input canister 650, and the process proceeds to step SG. Also, if it is determined that the mode is command mode, □Step SD
Then, it is determined whether reception of the application file is completed. Here, if the determination is affirmative, step S
The process moves to step F, sets the reception completion flag of the application file, and moves to step SG. On the other hand, if the determination is negative, the process advances to step SE, where the transferred characters are sequentially stored in the RAM 456, and step S
Move to G.

By instructing the "REQUEST"' key, the process proceeds to step S3, where the editing station 400 is set to the echo mode, and in step S4, an image editing program activation request signal is output to the image processing section 10.

Next, in step S5, the startup of the image editing program is confirmed, and if the determination is negative, the process proceeds to step S4, and if the determination is positive, the process proceeds to step S6. Step S6
In this case, the screen of the CRT 300 is, for example, entirely black, and the message area 340 is marked with "0N-LI" in green letters.
NE” is displayed to notify the operator that the request to start the biased program has been validated, and the mode display area 660 displays “' ECHOMODE” &
A message is displayed to inform that the editing station 400 operates in the echo mode, and a command input is waited for in step S7.

In step S8, input of a command key input manually from the console unit 200 is determined, and according to the determination result, steps sto, S15. S20. S25 and transition to S3o.

In the echo mode, the CRT 3Q[l screen editing function does not exist, so if there is an input from the screen editing key group 229,
Step S1. It is treated as an invalid input at step O, and the process moves to step 87' to wait for the next destination. Further, the same process is performed when the keys for ending the edit mode, that is, the edit reset key and the edit end key are input.

, if a command character in the key group 222 is input, the process advances to step 816 via step 815, the input command is transferred to the image processing section 10, and the system operates according to the command. For example, 1
As shown in Fig. 23-2, when the RE"' key is input, the characters "'RE" are displayed on the screen 301, and when the carriage return key 225 is pressed, a reader drive signal is supplied to the reader section 500 and the original is read. The image is read.

When the coordinate input request key 227, that is, the “position designation key” and the “area designation” 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 the “area specification” key is pressed, a message such as “ENTERTOP RIGHT PO8ITIO” is displayed in the message area 640.
N'', the left half of the working area 310 is displayed in white to prompt the operator to point A (see Figure 10-5), and the left half of the working area 610 is displayed in white to display image information. Edit area 315 is displayed.

When the operator indicates point A, a coordinate display line 312 is displayed in green, for example, in the vertical and horizontal directions of point A' corresponding to point A on the image editing area 311, as shown in Figure 22-3. In addition, the X and Y coordinates of point A, that is, XO and YO, are displayed in the user input canister 350 in units of myn. Next, “ENT” is displayed in the message area 330.
ERBOTTOM LEFT PO8ITION" is displayed to prompt the operator to input point B. When point B is input, in step S21, the vertical and horizontal lengths of the edited image are calculated from the coordinates of point B and the coordinates of point A. Xl and Yl are calculated, and then in step S22, the editing area specified by inputting the A point and B point is placed in the corresponding area 313 on the image editing area 611, as shown in Figure 22-4. For example, the message area 33 is displayed in red.
0 is “’OK! AREA l5RECOGNI
ZED” is displayed to inform the operator that the editing area specification is complete, and the user input canister 350 is displayed with XO, YO.
, XI and Yl are displayed as medium values. Next, the process moves to step S16, and these numerical values are sent to the image processing section 10.
Transfer to.

In addition, when editing an image by specifying a position, 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 input, for example, the coordinate display line 612 is displayed in red, and the user input area 650 displays XO and YO in the middle.When the editing station 400 recognizes the specified position in this way, the message area 660 “O”
K! PO8I'Tl0NIS RECOGNTZED
``'' is displayed to notify the operator that the coordinates have been validly input, and the numerical information of XO and yo is transferred to the image processing section 10.

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.
Waits for an input from , and by inputting a new command, the command and the specified coordinates that were displayed before execution of area specification or position specification are displayed on the working area 610 as shown in Figure 22-2. . In addition, if the operator instructs another command key after instructing the "area specification" key or position specification key and before inputting coordinates, the coordinate input for area specification or position specification will be performed. The waiting state is released and the “area specification” key or “position specification” key is released.
The command that was displayed before the ° key instruction is displayed in the working area 610.

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 alphanumeric key group 226. At this time, the process proceeds to step 826 via step 825, and “
Output the character information of 'KL' to the image processing section 10,
Request termination of the image editing program, step S
Proceed to step 27. In step 827, when the editing station control section 450 detects that the editing program of the image processing section 10 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;
That is, when there is an instruction using the ``Standard Work'' key, the ``Call Application File'' key, and the ``Create Application File'' key, the editing station is activated in step S30 as shown in FIG. 400
is set to edit mode.

Here, the “application file creation” key is
This is a key to instruct when creating a new application file, and the "Application file call" key is a key to instruct when calling and modifying an application file registered in the disk memory 9o. The "regular work" key is a key used to instruct an application file to be called up and a sequence of commands thereof to be sequentially transferred to the image processing unit 10 for image editing.

When these keys are input, in step S31, input determination is made 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 step S32
, the editing station control unit 450 uses a CRT 3QQ.
For example, set the screen to blue and write 'ENTERFILENo, AND CARRIA' in the message area 340.
GE RETURN ”, != Display L, request the operator to return the file number. Then, “ EDIT
MODE” is displayed in the mode display area 330 to inform the operator that the editing station 400 is in the edit mode, and the screen of the CRT 300 is returned to black.
For each case, perform the following processing according to the respective processing procedure.

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

When the application file number is entered in step S32, the editing station control unit 450 enters "ENT" in the message area 340 in step S40.
ERMENIJ! ' is displayed to prompt the operator to create an application file. And the cursor 302
is blinked in the upper left corner of the working area 310 to wait for command input, and then the operator creates an editing program by sequentially inputting the desired command group. By converting a command and adding a carriage return, the command is transferred to RAM 456 in edit station control 450 and simultaneously displayed in working area 610. In this way, the input command group is stored on the RAM 456, so
By instructing the screen editing keys 229, screen editing functions such as erasing the blinking line or character of the cursor 302, inserting a new line or character, and moving the cursor 302 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 line by line, and cursor 6
The working area 61 can also be moved up and down by 02.
0 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 LO (
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 614A defined by l is displayed in green.

Then, the left half of the working area 610 is made white,
Within that plane, LO (...) command and ADH (...
-) Displays the area 614B defined by the coordinates XO' and YO2 newly specified by the command in red. Also,
The file number FN of the image file is displayed at the upper right corner of both areas 314A and 614B.

Note that if the new editing area formed by XO', YO', XI, and Yl exceeds the editable area, the inputs of XO' and YO2 are invalidated, and a new valid input is awaited. The edit image (image area) displayed by inputting coordinate information is erased by inputting a command, and the command group being created is displayed 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 FIG. 26-6, the left side of the screen of the CRT 300 is set as a white wafer, and areas 616A and 616A defined from the coordinate information XO, YO, 617A is displayed in red, and 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, this is colored blue, for example, and the changed coordinate position information XO is displayed on the right side of the screen.
A region 31 defined by ' and YO' and Xl and Yl
6B and 617B are displayed in green.

In addition, a rightward arrow 618 is displayed in the center of the screen.
Indicates movement of the image.

When the display of image file movement is finished, the message area 640 displays °“END OF TRAC”.
EMODE"' is displayed to notify the operator of the end of the trace. When the operator then points to an arbitrary point on the console section 200, the command group of the application file being created is displayed again.

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 the application file, as described above, image file number 9 Tsumugi East image area (XO, Y
O, Xl, , Yl), edit image change position (XO
', YO') and the number of prints can be specified numerically, and programs can be created using them as variables to provide flexibility in image editing. For example, the following command group can be configured as an application file that performs trimming using the number of dots.

(1) RE (CR) The reader unit 500 reads the document and stores it in the sofa memory 22 (2) CR (N, O, F) (CR) File number N, area F (XO ,YO
,
Register as f4) LO(N, O) (CR) Change position of image file with file number N (5) ADR(P
) (CR) Set the change position to P (XO', YO') (6)
CL (CR) Erase buffer memory 22 (7) LD (N, O) (CR) Store image file with file number N in buffer memory 22 (8) DE (N, O) (CR) File number N
Delete the image file (,9) PR(S)
(CR) Copy eight copies of the image information stored in the buffer memory 22.

That is, the file number N9 editing image area is F.

An application file is created with the image position P and the number of copies As.

In this way, when the operator creates an application program and the creation is completed, the operator inputs the editing end key in step 834.

At this time, the process proceeds to step S35, and the editing station control unit 450 stores the 5TORETHI in the message area 640.
S,, coMmANDFILE? ” and R
It is confirmed whether the application program stored in the AM 456 is to be registered in the disk memory 90 as a file. When the operator denies this message and inputs the "N11 key," a negative determination is made in step S36, and the editing station 450 exits the edit mode, erases the screen 301, and returns to step S37.
and return to echo mode.

On the other hand, when the operator inputs the "Y I+ key" to request file registration, an affirmative determination is made in step 836, and the process proceeds to step 838, in which the file number set by the operator in advance in step S32 is registered. Then, the editing station control unit 450 sends an ED(...) command to the image processing unit 10 and obtains permission to transfer the application file.A file with the same file number as that file number is stored on the disk memory 90. If the file has not been registered, a negative determination is made in step S39 and the process proceeds to step 840, where the image processing section 10 permits the editing station control section 450 to register the file, and the 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 is transferred from the image processing unit 10 to the editing station control unit 450 indicating that a file with the same file number as the created file has already been registered, step 839
An affirmative determination is made in step S41, and the message area 340 is filled with “FILE ALREA”.
DY REGISTERED.

DELETE OLD "i'" Display L Te, asks the operator whether or not to delete the file with the corresponding file number in the disk memory 9°.

If the operator agrees, the process advances to step S42, and the editing station control section 450 sends the DE to the image processing section 1o.
(...) command and then returns to step 838. If the operator declines, the process proceeds to step 84.3, where the editing station control unit 450 enters the message area 340 ``ENTERFILE No, ANDC''.
ARRIAGE RETURN'' is displayed to prompt the operator to input a new file number. When the operator inputs a new file number, the process moves to step S38.

Note that if the response of the circular image processing unit 1o to the ED command is other than the error code '08,' the editing station control unit 45o 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 an application file call key is specified will be described. When the file number is input in step S32, the editing station 400 is set to command mode, and the editing station control unit 45
0 outputs an XR (...) command to the image processing section 10 according to the input file number. Therefore, in step S46, the image processing unit 10 calls the corresponding application file from the disk memory 90, and stores it in the RAM 4.
Transfer to 56.

When the editing station control unit 450 completes receiving the application file, it resets to the edit mode in step S47, then moves to step S33, and performs the same steps as in creating the application file.
Modify application files by deleting or inserting lines and characters.

Note that if an error code is sent from the image processing unit 10, the editing station control unit 450
The screen of 300 is erased to return to the echo mode, and an error code, an error message corresponding to the error code, and a status are displayed in message area 640 and status display area 660, respectively.

Next, the procedure for routine business input processing will be described. When the operator instructs the "routine work" key and inputs the file number of a desired application file, the editing station control unit 450 stores the specified file in the RAM 456, as in the case of calling an application file ( Step S32°S45-547). Then, in step 848, the editing station control unit 450
The command group stored in 456 is searched from the beginning to find variables N, F, P, and S. In step 849, if those variables are not found during the search, the process moves to step 853, and the command group of the application file is transferred one by one to the music diary 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 4
When the operator 50 first discovers the variable N, it displays a comment in the message area 640 of the CRT 300 asking for the file number to be entered manually, and then replaces the variable N with the numerical value entered manually by the operator. Next, when variable F is found, a message area 340 is displayed asking you to specify an image area, and variable F is changed to the values XO, YO, XI, and Yl input by the operator.
Replace with Next, when the variable P is found, it is displayed in the message area 340 to specify the image position, and the variable P is replaced with the values xo' and yo' manually entered by the operator, and the position specification input is changed to CR ( ) and LO(・
...) command, the process shown in Figure 23-5 is performed, and if it is related only to the LO(...) command, the process shown in Figure 23-2 is performed. Also, when the variable S is discovered, the message area 640
, the operator is prompted to input the desired number of copies, 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 26-6 to change the editing form to the working area 610. message area 64 in step S52.
Is 0 OK? The image is displayed to confirm with the operator whether the image editing format is as desired. If the operator negates the confirmation by, for example, instructing the "'N" key, the aii east station control unit 450 displays the CRT 3
00 screen is erased and the process moves to step 837. On the other hand, if the operator, for example, instructs the +i Y ++ key and affirms this, the process moves to step S53, where the editing station control unit 450 saves the screen as it is and sequentially sends the command string to the image processing unit 10. and execute the specified program.

The image processing unit 10 echoes the transmitted command character back to the editing station control unit 450, and the editing station control unit 450 displays the command i in the status display area 660 to inform the operator of the status of this system. Recognize it.

When the image processing section 1° finishes executing the series of commands, the editing station control section 450 proceeds to step S37, ends the routine work, and returns to the echo mode. If an error occurs in the process of command execution by the image processing section 10, the editing station control section 450 interrupts the transmission of the command, erases the screen of the CRT 300, and displays an error code in the message area 340. and switch to echo mode.

It should be noted that in the above-mentioned processing in the edit mode, including processing, command file creation, command file calling, and routine work processing, the operator instructs the edit reset key during the input processing in steps 833 and 350. If so, the screen of the CRT 300 is immediately erased, and the process moves to step S37 to return to the echo mode. Also, if there is an end input, +l! K to the li image processing section 10
The L command is output, the online state between the image processing unit 10 and the editing station 400 is canceled, and the process proceeds to step S2.
to move to.

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

(1) A reader unit that reads a document image, an image processing control unit that controls image processing, stores processed images, etc.
An editing station that edits image information, an optical fiber interface that mutually communicates image information between this system and other systems on the optical fiber network, and an optical fiber interface that performs mutual communication of image information between this system and other systems on the DDX line network. Since the image processing apparatus of the present invention is composed of a DDX interface for mutual communication of image information 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, 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 section is provided with a buffer memory for temporarily storing image information, and is provided with a switching device.
The flow of image information within the device of the present invention and image information transferred from other systems to this system via an optical fiber cable is switched, and one or more of the buffer memory, optical fiber interface, and printer section are selected. Since the information can be transferred to each part, reading of image information, short-range communication, and copying can be processed in parallel, and image processing time can be shortened.

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

(4,) When communicating image information between this system and other systems via the DDX line network, documents of a predetermined size must be sent between this system and the other systems within a predetermined time. Signal R indicating that image 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
It is possible to reduce the transmission time of image information using a DX line.

(5) The DDX interface converts the image information of one line in the vertical direction of the original image into a run-length encoder, and then data compresses the run-length encoded image information for one line using a two-dimensional encoding method. When performing this, the run length of one line of image information is 2623.
If the length exceeds 2560, data compression is performed by adding one make-up code corresponding to the required run-length length following the make-up code corresponding to the run-length length 2560, and then adding one terminating code. Now, when communicating using the DDX line,
Since the total number of lines of the concave image of the original to be transferred can be reduced and data compression can be performed efficiently, the transmission time can be shortened.

(+3) When communicating image information between this system and another system via the DDX line network, the image processing control unit sends a signal CRQP requesting connection to the other system and a DDX A signal CNQ requesting to capture the line, a signal NRYP indicating that the image processing control unit cannot be in a state where it can send or receive image information within a predetermined time, and a signal NRYP indicating that the image processing control unit cannot send or receive image information within a predetermined time. It transfers signals RDS and RDR, which respectively indicate that a state may occur, a signal RQS which indicates that one line of image information is being supplied to the DDX interface during the valid period, and image information SDT. Also, D.D.
The X interface sends to the image processing control unit a signal CIP indicating that a call has been received from another system, a signal NRYD indicating that the DDX line cannot be connected, and a signal indicating that the DDX line connection has been completed and communication is possible. A signal CND indicating
, 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 it is in a mode in which it can receive image information from other systems, and one line of image information. A signal RQS requesting transfer, a signal RVA requesting reception of one line of image information received and demodulated by the DDX interface from another system, and image information received and demodulated from the other 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 this system and another system, both systems can communicate with each other. When the transmission conditions of both systems are established, a transmission ready message is sent to each other, and the calling system starts transmitting image information line by line, and the called system starts transmitting image information line by line. Transmission errors are monitored for each line that is transmitted. 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 serially transmitted from other systems on the optical fiber network into electrical signals, and reproduces commands and image information related to image recording from other electrical sources to create images and images. The commands and image information related to image recording for other systems that 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. In the system that performs
Image information can be recorded without requiring any operations, and image processing can be accelerated.

(9) The stroke count processing section (CPU circuit block) sends a status request to the printer section, and the printer section notifies the image processing section of the status of the printer section in response to the status request. The recording school preparation command is sent out according to the status, and the printer unit records image information in response to the command, so the image processing information forming unit can recognize the status of the printer unit. Image recording can be performed directly from the side, and thus image recording can be performed effectively.

(10) Image (The urine processing control unit is equipped with a disk memory, and 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, edited, etc.) can be easily done.

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

(12)! The J-reader section is equipped with a reader operation section, and the application file stored in the disk memory can be activated from the reader operation section, so that routine work of image editing can be easily performed on the reader section side as well.

(13) Image information can be sent from the reader operation unit to multiple other systems on the optical fiber network and DDX line by specifying the destination, and in particular, to other systems on the optical fiber network. When sending, you can specify the number of copies for each destination, so 11! ui Image information can be transmitted easily and quickly.

(14) The editing station has a command menu section where the operator inputs a group of commands for image editing, and an editing station.
Since a digitizer is provided to convert the coordinates of the 1llll image, information for image editing can be easily converted.

(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 the work while interacting, you can easily create a collection of concave image fences and an abbreviation file for image editing, and even if there is an error in the input information, etc., you can quickly deal with it. This allows you to edit images efficiently.

(16) A command to start the reader unit is provided in the command menu section of the editing station, and by inputting that command, the reader unit (= original image) can be read. When it is necessary to cause the reader section to execute 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 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.
) can produce the same effect.

(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. It can be done easily.

(19) A command to start the printer section is provided in the command menu section, and the printer is activated by inputting that command.
Since the printer section can be caused to perform the image recording operation, the same effect as the addition (16) can be obtained when it is necessary to cause the printer section to perform the recording operation during image editing work.

(20) The command menu section includes command 1 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. Since a command for temporarily storing data in the buffer memory is provided, image editing can be performed easily, reliably, and quickly.

(21) Since the area on the digitizer is made to correspond to the address in the panzer memory, image editing can be easily performed without errors.

(22) When editing images and creating editing programs, the CRT 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.

(23) When editing images, etc., if the image editing area specified by the editing station exceeds the editable area of the device, a warning will be 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 assigned to each specified 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 CRT screen, the execution form can be visually confirmed, and therefore not only the operator who created the editing program but also other operators can can be done easily and reliably.

(26) When creating the Miit collection program, we made it possible to set the number of recordings, editing area, etc. as variables, making the system more flexible and making it easier to edit images. It can be done easily.
