Description

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

BACKGROUND ART Conventionally, as image processing apparatuses, copying apparatuses as means for duplicating original images, facsimile apparatuses as means for transmitting original images to remote locations, and the like have been widely used. When copying an original, the general copying devices currently in use make copies of images of the same size as the original.
Enlarged or reduced copies can be made. Alternatively, when it is necessary to change the density of one image, it is possible to uniformly change the density 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 A copying apparatus has been proposed that has an image editing function such as changing the image density of only a portion of the image. However, as a copying apparatus is equipped with many such functions, the apparatus becomes more complicated, and furthermore, 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 a copy at the same time as sending the original, a secondary copying device is 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 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. It is about providing.

A signal line 80-103 from the I10 processor 80-1 to the bus arbiter 80-2 and the bus controller 80-3 is a signal line that transmits the status signal of the I10 processor 8o-1 to both of them. Further, a signal line 80-104 connecting the 1107' processor 80-1 and the address/data buffer block 80-4 is a signal line for transmitting an address information signal and a data information signal, and is a signal line for transmitting an address information signal and a data information signal.

8 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 the multipath 30 and internal bus 80-5 via 115 and 5o-tte, and receives and passes address information and data information to and from these buses.

Internal bus 80-5 of DMA controller 80 includes an 18-bit address bus with 84 kilobytes of address space and an 8-bit data bus.

80-6 is a clock generator, which generates a clock signal of a predetermined frequency based on a reference oscillation output from an external crystal oscillator or the like through a signal line 80-120,
0 processor 80-1. The bus arbiter 80-2 is supplied to the bus controller 80-3 and the synchronization signal generation circuit 80-7, and is also supplied to the T1 via the signal line 80-121.
0 processor 80-1, bus arbiter 80-2, and path controller 80-3, it outputs an initial reset i signal at power-on and a manual reset signal. In addition, the clock generator 80-4 is connected to the multipath 30 via the signal line 80-122.

Determines whether or not the multipath 30 enters the wait state and whether or not the wait state is released, and outputs a bus ready signal to the T10 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 IORC signal and INTA signal and a chip selection signal supplied from the address decoder 80-10 via the signal t&80-125. generate.

By supplying this signal to clock generator 80-6 via signal line 80-128, T10 processor 80-1 is enabled to proceed to the next operation.

ROM 80-8 stores a microprogram for T10 processor 80-1. ROM from internal bus 80-5
The signal line 80-130 leading to 80-8 is an address signal line that transmits information indicating the address of the fetched instruction code when the T10 processor 80-1 fetches the microprogram stored in the ROM 80-8. The signal line 80-131 leading to the ROM 80-8 is a data signal line for the fetched instruction code.

The address decoder 5o-to selects the ROM 80 based on the chip selection signal of the T10 processor 80-1 supplied via the internal bus 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 bus 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 an identification signal for identifying whether the address information is latched in the address/data buffer block 80-4, the address information for the internal bus 80-5, or the address information for the multipath 30, address decoder 8
0-10 performs its 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 bus 80-5 will be described. First, the multipath 30 and the case where the information is received and passed will be described. When I10 processor 80-1 outputs address information to address/data buffer 80-4, /Hess controller 80-3 outputs address information to 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 /Hess arbiter 80-2 supplies the AEN signal to the address/data buffer 80-4, and the address/data buffer γ
80-4 transfers the latched address information to multipath 3
Output to 0. Here, if the DMA controller 80 is in write mode and the multi/< bus 30 has been acquired, the I10 processor 80-1 outputs data information to the address/data buffer 80-4, and /cheetah/<Rough 780-4 outputs data information to multipath 30 upon receiving the DEN signal from bus controller 80-3. In contrast, when DMA controller 80 is in read mode, address/data buffer 80-4 reads data information on multipath 30-hi and supplies the data information to I10 processor 80-1. The I10 processor 80-1 reads data information from the disk memory 8, which is the data transfer destination.
XAC 0 to I10 processor 80-1
This is done after confirming the K signal.

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 bus arbiter 80-4 -2 does not require an AEN signal. Further, whether or not to output data information to the internal bus 80-5 is determined by the bus controller 80-3 through the PDEN control.
Determined by the signal.

As the disk memory 80, for example, WIIS-10 manufactured by Nendo 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.
0-142 and 80-143, respectively, the synchronization signal generation circuit 80-7 and the I10 processor 80-
Connected to 1.

The data buses 80-140 transmit command information, result information, data information, and status information, and the former three pieces of information are collectively assigned one address to form a set of information, and the three pieces of information are sequentially transferred to the disk. They are distinguished by their input and output to the controller circuit.

Further, one address is individually assigned to the status information. Here, the command information is information that specifies an address and the number of bytes on the disk memory 90, and the result information is information that specifies the error check results during data transfer between the DMA controller 80 and the disk memory 90. This is the information shown.

The signal line 80-142 transmits a command busy (CBUSY) signal, and the synchronization signal generating circuit 80-7 identifies the above three pieces of information and status information. In addition, command information,
a set of information consisting of result information and data information;
The timing at which the data becomes ready is different for status information, and the read mode and write mode are also different, so the synchronization signal generation circuit 8
0-7 is l0R transmitted via signal line 80-112
C; signal and C transmitted via signal line 80-142
BtlSY signal, four types of waiting times are created and applied to the clock generator 80-6 from the signal line 80-128, and the above-mentioned two waiting times are supplied to the I10 processor 80-1.
The set of information is identified and captured based on the timing of the clock from the clock generator 80-8.

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

The packa memory bank space has a capacity of 886 kilobytes from address 1'00008 to address EFFFFH, but as mentioned above, the Yatsufa memory circuit pro-nk 20
The storage capacity of is 1185840 bytes, which cannot all be stored in the bank space of the buffer memory. The buffer memory space is then divided into three banks: bank 0. bank! and bank 2, C
The bank is switched by the bank switching signal outputted from the PU circuit block IO via the signal line 132 (see Figure 4 and Figure 8-2), and the specified bank is assigned to the memory map as shown in Figure 8. . This division and allocation process will be described in the explanation of FIGS. 9-1 and 8-2.

FIG. S- shows the address map of the buffer memory 22 within the buffer memory circuit block 20. FIG. This buff
7 Memory 22 is A4 size (297m+nX 210+
It has the ability to store information obtained by decomposing a document (nm) into 16 pixels per mm. The league unit 500 main scans the A4 size document in the vertical direction (29? + om direction), and then the CCDs 5? The pixels are supplied to the image processing control section 100. Also, league part 5
00 sub-scans the document in the width direction (210 mm direction),
CCD570, 580 and 580 are also 1m in this direction.
Since 18 lines are scanned per meter, the document is scanned 3 times in the width direction.
380 lines are scanned. Therefore, an A4 size document is decomposed into +59813720-bit pixels, and the 4752-bit pixels are serially supplied to the image processing control section 100 3360 times.

The procedure for assigning addresses to the image information supplied in this manner and storing them in the backup memory 22 will be explained. First, an A4 size document is divided into medium blocks of 1 mm x 1 mm squares, each consisting of 82370 blocks.

One unit block has 16 lines with 16 bits I.
In other words, if there is 256 bits of image information, 16 bits in the vertical direction are treated as one word, and one address is given to each word, one medium block is composed of a group of pixels with 16 addresses. become. 4 for the first line, that is, 1 line of the first scanned document
752 bits of serial image information is 1m in the vertical direction of the document.
It is divided into pixel groups of 16 bits each corresponding to m and is supplied to the image processing control unit 100, and the first 16 bits are
The pixel group of bits is at address 0OOOOOH of the buffer memory 22, the next 18-bit pixel group is at address 0OOIOH, and similarly, the pixel groups of 16 bits each are sequentially moved to address 18 (IOH).
For each address, 00020H address.

(44) 00030H1% address..., it is stored like 01280H address.

The CPU circuit block 10 uses the address counter 21-6 to check the backup memory 22 for each line.
This is done by setting the initial value to . Also, when outputting image information from the buffer memory 22 to the printer section 600, one readout is performed for every 18 addresses starting from the initialized 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 2818. In this way, 1536 lines from the 1st line to the 1536th line (9f1mm in the width direction) are created from address 0OOOOH to 6F5FFH.
This address space is stored in the buffer memory 22.
Set the upper bank to 0.

Next, 1 from the 1537th line to the 3072nd line
Similarly to bank 0, 538 lines are stored from addresses 70000)1 to DF5FFH, and this address space is designated as bank 1 on the buffer memory 22. Furthermore, the fourth
5) Store 288 lines from the 3073rd line to the 3360th line from address EOOOOH to address F4EIFH, and make this address space bank 2 on the sofa memory 22.

If you use the method of storing 1 word of image information with 1 address as shown below, 1+++1llX1mm
The buffer memory 22J is constructed using a square as a unit block.
This means that the entire area of an A4 size document can be stored in consecutive addresses of - and . As a result, when the operator specifies the image processing area in mm units using the console unit 200,
When registering a designated area in the disk memory 90, DMA transfer can be performed simply by setting the start address and end address of the designated area, and the image information fecpu circuit block 1
It is possible to transfer data at high speed without going through 0.

That is, by specifying a set of the first address and the last address, image information of 16 main scanning lines (1 mm@) can be transferred to D.
Since MA transfer is performed, fewer address settings are required for 1 MA 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 with a vertical length of 20 mm, the address setting by the CPU circuit block 10 is 2.
This will result in 0 times.

Further, since the address corresponds to the position on the original image in units of 1111, when editing the image, the operator only has to specify the position on the original in units of 111 ml, which is convenient. In addition, in the unimplemented example, since CCDs 570, 580 and 590 having a reading capacity of IB pips per 1 mm were used, it was decided that 1 address corresponds to 16 bits in the vertical direction, but the number of bits corresponding to 1 address is may be other values depending on the capabilities of its CG[15?Q, 580 and 590, and may also be in units other than mm, e.g.

Of course, the same effect can be obtained even if the address is set in inches or the like.

Figure 8-2 shows the multipath 30 and buffer memory 22.
Shows the address map when viewed. 0O in Figure 9-1
OOOH ~ [The address space at address 1F5FFH is set to bank 0, ? The address space at addresses 0000H-DF5FFH is bank 1, and the address EOOOOH-F4EIFH is bank 2, and these spaces are designated as addresses 100OOH to EEBFE)1 and 100OO, respectively, as shown in Figure 8.
Address H-EEBFEH corresponds to the address space of 100OOH to 39C3EH. Multipath 30 is 16
Although it has a bit data bus and a 20-bit address bus, the area that can be accessed by this multipath 30 is 1 megabyte. In other words, 8-bit data is
When accessing 16-bit data, it will span two addresses, so in this case, as shown in Figure 8-2, every other consecutive address for 16-bit data will be accessed. Addresses are assigned so that 16-bit data is input/output only when an even address is accessed.

Since the actual address in the buffer memory circuit block 20 is the address shown in FIG. 8-1, 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 21-28 in the buffer memory circuit block 20, as described above. . These address converters 21-28 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. 91 is a drive, numbered 0.1, . . . , corresponding to the number of disk devices. ...and number it. In Kinomi Nagitaru, only one disk device, that is, the number 0 drive is used. The drive 81 has three heads 92, and each head 92 has 354 tracks 83.
Each track 83 consists of 18 sectors 84, and each sector 84 can store 512 bytes of data. Therefore, the storage capacity of disk memory 90 is approximately 10 megabytes.

In the disk memory 90 having such a configuration, the first
Addresses on the disk memory 80 are changed according to a fixed sequence as shown in Figure 0-1 (B), and data is accessed continuously. As shown in this figure, sequence number SN, head number HN, and track number TN
There is a relationship determined by the following equation (1).

5N=3X TN+HN (However, HN=O~2.
TN=O~353) (+) In other words, when a certain sequence number SN is determined, the corresponding track number TN
and the head number HN are determined, and the address of the head 92 and track 93 to be accessed next is the sequence number SN, which is the previously determined sequence number SN plus 1.
These are the head number and track number obtained in response to +1. Sectors 84 in track 93 are accessed in ascending order of sector number 5CTN.

FIG. 10-2 shows an index table provided in a predetermined area in the disk memory 80, and in this embodiment, the usage status of the disk memory 80 is managed by this index table. -0,) Of the sectors 84 with rack number TN=0, the sectors with sector numbers 5CTN=0 to 13 are used as the index table area, and the sectors with sector numbers 5CTN-0 to 8 are used as the disk memory. 80, and sector numbers 5CTN-9 to Sector bitmap table 94A indicating the usage status of each sector on
Allocate 13 sectors to the file index table for file management. Sectors with sector numbers 5CTN=0 to 13 are stored in the fixed area 13 of RAM10-3 by a program (open program) that reads the index table into RAM10-3 in CPU circuit block lO.
From address 000H? The BFFH address is written and subjected to a predetermined operation, and then written to the disk memory 90 again by a program (close program) that stores the fixed area of RAM10-3 in the disk memory 80.

As shown in Figure 10-3, the sector bit map table divides the area 134A into 1062 blocks of 4 bytes each from 5N=O to 5N=1081 in order of decreasing sequence number SN, and Data indicating the usage status of one track, that is, 18 sectors, is stored by allocating one bit to each sector. As data indicating the usage status of a sector, for example, if a certain sector is in use, "l'" is stored in the sector bit corresponding to the safeter, and if it is unused, "0" is stored.

When registering a new data file in the disk memory 80, find an area where the number of consecutive sectors required for registration are empty, obtain the sequence number SN and sector number 5CTN corresponding to that area, and then °1” in the sector bit corresponding to the sector.

Store. Conversely, when deleting a data file,
°0''' is stored in the sector bit indicating the corresponding area. However, "i" is stored in advance in the bit corresponding to the index table, that is, block 0, and writing to this 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 90.
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 Part 10-
Shown in Figure 4.

File index block FITI has status A, MAX block, l block size and current)
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 (32H).
Set to . 1 block size is per l file,
Indicates the length of the index of various data related to the file, and in this example, the length is set to 38 as described below.
(28H) bytes. The current B number stores the number of files registered in the disk memory 80, and stores the number of files registered in the disk memory 80.
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. 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.

FIT2 and FIT3 indicate file index blocks for file type 0 and file type 2, respectively, and each stores 38 bytes of data. In FIT2 and FIT3, R9
V is a 2-byte area used for system expansion, and is unused in this embodiment. File No. is a 2-byte area for identifying the file number when the operator arbitrarily assigns a number from 1 to 88 to a file and registers it in the disk memory 80. The file type is a 2-byte area in which data of the above-mentioned file type °゛0゛° or °°2゛° is written. The bank and address in F1-3 are RA on CPU circuit block lo.
These are 2-byte and 4-byte areas, respectively, which indicate the bank and address of M10-3 and are used when storing application files in RAM10-3. The byte count is a 6-byte area that stores the data length of the registered file.

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.
The track number and sector number 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, YO in FIT2
, XI and Yl are each 2-byte areas,
When the file type is "PaO°", coordinate data indicating where on the copy paper the image information of the area to be edited is placed is stored.
As shown in Figure 0-5, place the manuscript on the manuscript storage section 240, and use the stylus pen 280 to edit the editing area (diagonal line) closest to the 0 point - point A and point B furthest from the 0 point. By instructing, the coordinates xO and YO of point A, the vertical length x 1 and the horizontal length Yl of the editing area are determined, and these values are stored in hexadecimal. File type 2
In the case of , as shown in FIT3, XO of FIT2,
The areas corresponding to YO, XI and Yl are unused areas.

When transferring a certain image data file from the disk memory 8o to the buffer memory 20, first, the file number is specified, and the open program transfers the index table to the RAM 10-3 to obtain the index block of the specified file number. Next, the address on the buffer memory 22 is calculated from the data stored in XO, YO, Xl and Yl of that block, and the image information in the disk memory 90 is transferred to the corresponding area of the buffer memory 22 by be transferred.

Also, when changing the position of the editing area on the copy paper,
Since ×1 and Yl are unchanged, only XO and YO are used as parameters, and only xO and YO need to be changed by a one-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 sets the file to file type 1.
The file index block is configured similarly to FIT3.

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

(1) With the device of the present invention, the vertical direction (2
97 mm direction) is one line, and the resolution is 16 bits/mm, the maximum run length, that is, 1
When the lines are all white or all black, the run length is 4752, which exceeds the maximum expression range 2823 (=2560.133) of the expanded M)1 code.

(2) In the device of the present invention, 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 IIDX interface 60 is MH encoded 17, 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, (i>The number of lines to be transmitted is made small to reduce the transmission time, and (
11) 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 save the time of repeating MH encoding every time by setting the crmeter K to a small finite value, and the parameter K is set to infinity. The reason why this can be set 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 finite value to minimize the reading error. This is because it is lost.

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

First, image information for 1 life (4752 bits) transferred from the buffer memory 22 via the signal 1i 137 is transferred to the line buffer 80 via the data/clock interface 80-1 and the write switch 80-3.
-4.80-5 or 60-6. This image information is transferred to line buffers 130-4, 60-5 or 60-6 at a transfer rate of 1 bit per 0.1 microseconds (ps) in synchronization with a 110 megahertz (MHz) clock signal. . That is, the transfer time of the image information of 1 line is 475.2 gs. The image information of the first line that is transferred first is switched by the switch 60-3.
First, the image information is supplied to the line buffer 60-4, and when the line buffer 80-4 finishes storing the image information of the first line, the switch 60-7 opens the gate of the line buffer T60-4, and the line buffer 60-4 Then, the gate 80-8 is closed and the stored image information is transferred to the RL counter 80.
-8, the white and black run lengths of the information are counted, and the run length encoded first line image information is converted into MH code by RLMMH/MR converter 8O-1o. be done. While the line buffer 60-4 is outputting image information, the switch 60-4
-3 closes the gates to line buffers 80-4 and 80-6, opens the gate to line buffer 80-5, and supplies the second line of image information to line buffer 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 80-7 by the switch 80-7, and the relative pixel information from the first line is The change position is counted and RLMMH/
MR encoding is performed by an MR converter 80-10. The image information of the third line transferred to the line buffer 80-8 is also processed in the same way as the second line. The image information output from 60-6 passes through RL forward/reverse counter 60-7 and then goes to R.
LM) is supplied to the I/MR converter 60-10, and the MR
encoded.

Next, the run-length encoded image information supplied to the RL44 MH/MR converter 60-10 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 MH code, so the MH code is further extended by the following method.

(1) Normal MH when run length RL < 2580
Expressed by sign. That is, when RL<84, it is represented by one terminating code.

If 64≦RL<2560, it is represented by one make-up code and one terminating code.

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

(a) 2580≦RL≦2823 = 2580 +
83 case (1), one make-up code (in this case, the make-up code of 2560) and 1
terminating codes.

(b) When 2B23<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),
A 2560 make-up code is immediately followed by a terminating code of the same color (a), and a 2580 make-up code is followed by a make-up code of the same color and then a terminating code (b). There is. An example of processing in case (2) is shown below. The underlined numbers are the added makeup codes.

Example: 2580 = 2580 = 2580 = 2580 + 1 2B23 = 2580 + 63 2824 = 2580 + 84 ÷ 0 4289 Wealth 25 EIO + 172841 4752-2580 + 2178 + 18th C), and in Fig. 12-1 The meaning of each signal flowing along the signal line interconnecting the image processing unit IO and the DDX interface 60 will be explained.

Figure 12-2 shows each signal, its name, image processing unit 10 and D
Direction of signal between DX interface 60 (arrow)
FIG. Here, FC and SG are a safety ground line and a signal ground line, respectively.

The call request signal (CRtJP) is sent by the image processing unit IO to [l
For the DX interface 60, connection with other systems (
This signal requests a connection raw signal (call origination).
CND) is energized and deenergized at the same time, and when the connection disable signal (NRYD) is energized, it is treated as invalid. The paging signal (arp) is a signal from the DIIX interface 60 that indicates to the image processing unit 10 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 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 10 requests the DDx interface 60 to connect to the DDX line, and is activated at the same time as either CRQP or CIP is activated, and NRYD is activated. It is considered invalid when the Also, while it is necessary to capture one 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 IO cannot be in a state capable of transmitting or receiving within 6 seconds. NRY[) indicates that the line cannot be connected when the DDX line 800 is busy or the not ready switch of the NCU 302 is activated. This NRYD line is always energized or deenergized depending on whether line connection is disabled or enabled, respectively. Furthermore, if the CHD is not activated even after a certain period of time has passed after CRQP is activated, the image processing unit 1o determines that connection is not possible.

CND is caused by the activation of CRQP or CRP and the activation of CNQ.
It is activated when the communication conditions are established, indicating that the line connection has been completed and the system is ready for communication. CNI] is de-energized when CNQ is de-energized or when the other station disconnects the line. Clear to send signal (RDS)
) and ready-to-receive signal (RDR) indicate that the image processing unit IO can be in a state where it can transmit and receive image information for one A4-sized document within 6 seconds, and indicate CNQ activation and At the same time, R113 or RIllI'
l is energized.

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. It is also possible to perform reception or transmission immediately after completion of transmission or reception, respectively. ' The Ready to Transfer signal (RDT) is activated within 6 seconds of the MDS or MDR being activated, indicating that image information is now available for transfer in transmit or receive mode.

The transmission data request signal (RQS) is turned on and off at regular intervals, and the DDX interface 60 requests the image processing unit 10 to transfer image information for one life. 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 buffer memory 20 to the DDK interface 60.
DT) is transferred. RQS is de-energized upon completion of its transfer. The RQS repetition period is set longer than the minimum transmission time. SVA is activated in response to RQS, indicating permission to sample SDT in synchronization with the transmission clock (SCK), and deactivated upon completion of SDT transfer.

The RVA is activated at regular intervals, requests the DDX interface θ0 to receive one line of expanded image information (R[]T) received from another system, and synchronizes the RDT with the reception clock (RCK). Indicates that sampling is permitted. The repetition period of RVA is R
It is similar to QS.

SDT and RDT are two pieces of transmitted and received image information in black and white, SCK and RCK, respectively.
are the sampling clocks of SDT and RDT, respectively.

In the device of the present invention, when transmitting between this system and another system on the DDX line 800, the direction of the transmission is between the calling system (calling station) and
The RDS and RDR are compared in both the system on the called side and the called side station (called side station), and the decision is made as shown in Fig. 12-3, thereby preventing errors in the transmission direction.

That is, in FIG. 12-3, as shown by the arrow indicating the energized state and the O1 transmission direction, and the deenergized state and the transmission disabled state by x, only the RDR on the calling side and at least the RDS on the called side are shown. When 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 calling side's RDS and at least the called side's RDR are activated, and when the calling side's RDS
When the RDR and at least the RIIR 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 other than those described above.

FIG. 12-4 shows an example of a procedure for transmitting data between a calling station and a called station. Here, ID
S is a transmission capability identification signal, which identifies the transmission capabilities of the calling and called stations, i.e., RDS and R
[This is a signal that informs each other of IR. For example, the transmission format is “OOOOORDS RDR10
” will be sent sequentially from the most significant bit to the least significant bit, and both stations will transmit the Rf of the tree system.
From the IS and RDR and the RDS and RDR of the other station, the transmission direction is determined as shown in Figure 12-3.

RDY is a transmission preparation completion signal, and its transmission format is, for example, "ooo too to °", which is sent in the same way as in the case of IDS. Indicates that the preparation for sending and receiving image information for one sheet has been completed.

H old is MH encoded first line image information, MR2
~MRn+1 (t≦n≦3380) is MR encoded image information of the 2nd to n÷1 lines, MHn is M)I encoded image information of the nth line, and MRn+1
~MR3380 is MR encoded n+, 1st to 33rd
60 lines of image information, M) 11 to MR3360
shows the image information for one A4 size document.

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

[]CN is a line disconnection signal, and its transmission format is, for example, "01000010" as T[lS
is sent in the same manner as above to notify each other that the line has been disconnected.

Immediately after the line is connected, the calling and called stations
Second, it starts transmitting the IDS continuously and repeats the transmission at least three times until its own station is ready for the transmission mode. Here, for example, at time A, if the transmission direction cannot be determined, transmission is disabled (see Figure 12-3); and both stations send DCN to each other and disconnect the line. When their own station is ready, both stations send RDY at least three times until both stations are ready, and when both stations are ready and RDY is sent from both stations, that is,
At time B, the called station enters the receiving state without sending control signals to the calling station, and the calling station enters the transmitting state.

When transmitting image information for one A4-sized document, for example, if a transmission error occurs in the image information of the nth line at time E, the called station sends 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 3380th line.

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

(6) Image editing method Image editing is performed by appropriately performing DMA transfer between the buffer memory 22 and the disk memory 90. That is,
Image information for one A4 size document read by the league section 500 is stored at a predetermined address in the buffer memory 20, and a part of the image information is stored in the disk memory 80 via the DMA controller 80. Therefore, by erasing the buffer memory 22, restoring the image information previously stored in the disk memory 90 to the desired address space of the buffer memory 22, and copying the image data in the printer unit 600, unnecessary parts of the original can be removed. You can get a cropped copy of the .

Image editing such as changing the image position and cropping is performed according to an image processing program created based on commands (described later) input from the command menu section 220 shown in Figure 3-2. Such an image processing program is
The image processing program that can be stored in the disk memory 90 and stored therein is defined as an application file. Further, image 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, a two-digit file number is given to the file as a file name, and an instruction is given as to whether or not the file can be deleted. do.

Extract the image information within the range of Ml from the stored image information, and add the file number ゛°0 to the old image information.
It is registered in the disk memory 90 with a suffix of 1°. Similarly, for the second document L2, the image information M2 is extracted by specifying the 0 point and the D point, as shown in FIG.
is registered in the disk memory 80 with the file number "02" added to it. Next, the buffer memory 22 is completely erased, and as shown in FIG. and image information in M2 are transferred to address spaces corresponding to areas N1 and N2 of the buffer memory 22, respectively. That is, the buffer memory 22 stores image information for one A4 size document, and the image information Nl and N2 are stored in the buffer memory 22 as shown in FIG.
) and are stored in an arrangement like this.

The contents of the buffer memory 22 are sent to the printer section 6o.

The edited image L3 is then transferred and copied to obtain the desired edited image L3.

(6,1) Meaning of commands The editing commands used when editing images will be explained. Editing commands are input through the command menu section 220 on the console section 200, as shown in FIG.

(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. CRT300 has 40 horizontal characters,
It has a screen 301 that can display 24 vertical lines. 22nd-
FIG. 1 shows an example of the display division of the screen 301, where 310 from the 1st line to the 19th line is a working area, in which characters transferred from the image processing unit IO to the editing station 400 are displayed, etc. . 320 on line 20
is a blank area, no display is made in this area,
The boundaries between the working area 310 and the following areas are made clear to the operator. 330 in the 21st row 1'' 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 1O to notify the operator.

As other initialization, when a command is input, the command echoed back from the image processing section 10 is displayed in the working area 310, the carriage return code is recognized, and the next command sent back from the image processing section 10 is displayed. The 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 line by line, so that the command is always stored in the working area 310. Do it like this.

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 request, i.e., "I'1EQ
As a message to accept the UES key, ``'NOT''
READY, ENTER REQUEST KEY”
is displayed and waits for the input of the "REQUEST" key in step S2.

Editing station 400 operates in two main modes: echo mode and edit mode. In the echo mode, the character screen input by the operator via the console section 200 is directly transferred to the image processing section 10, and 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, the RAM 45fl in the editing station control unit 450
The image data is temporarily stored in the image processing section 10, and after being arbitrarily modified by the operator on the CRT 300, it is transferred to the image processing section 10. Further, 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 1O 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 SH, where the character echoed back 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 can be changed to the user person Canilia 3.
50, and the process moves to step SG. Further, if it is determined that the mode is the command mode, the process proceeds to step SD, and it is determined whether or not reception of the application file is completed. Here, if the determination is affirmative, the process moves to step 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 proceeds to Stella 7'S3, the editing station 400 is set to the echo mode, and in step S4, an image editing program startup request signal is output to the image processing section 10. Next, in step S5, 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. In step S6, C;
For example, the screen of the RT300 may be entirely black, and the message area 340 may display ``θN-LINE'' in green text to inform the operator that the request to start the editing program has been validated, and the mode may also be displayed. The area 330 displays "ECI (ONCl[lE") to inform that the editing station 400 operates in the echo mode, and waits for a 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. S15,920. The process moves to S25 or S3O.

In the echo mode, the screen editing function of the CRT 300 does not exist, so if there is an input to the key group 229 related to screen editing, it is processed as an invalid input in step SIO, and the process moves to step S7 to proceed to the next step. Wait for input. 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 S18 via step S15, where the input command is transferred to the image processing unit 10, and the system operates according to the command. . For example, as shown in FIG. 23-2, when the "'RE" key is input, the characters "RE" are displayed on the screen 301, and by instructing the carriage return key 225, a league drive signal is supplied to the league section 500. Then, the original image is read.

When the coordinate input request key 227, that is, the ``° position designation'' key and the °° area designation key, is specified, step S
Proceeding to step 20, 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 specify the °°area designation'' key, the message area 340 displays, for example,
"ENTERTOP RIGHTPO8ITION" is displayed, the left half of the working area 310 is made white to prompt the operator to point A (see Figure 1O-5), and the left half of the working area 310 is made white;
An image information editing area 315 is displayed.

When the operator indicates point A, a coordinate display line 312 is drawn, for example, in green, in the vertical and lateral force directions of point A', which corresponds to point A, in the image editing area 3117, 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 ml11. Next, in the message area 330, °“EN
TERBOTTOM LEFT PO9ITION" 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. ×1 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 311, as shown in Figure 22-4. For example, the message area 330 is displayed in red.
°'OK I AREA l5RECOGN IZ
E[l” is displayed to notify the operator that the editing area specification is complete, and the user input area 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.

Furthermore, when editing an image by specifying a position, the user instructs the °゛position specification゛key. In this case, only one point is designated, that is, only point A in the case of area designation. When that point is input, for example, the coordinate display line 312 is displayed in red.
and xO and YO are displayed in the user input canister 350.
is displayed in units of 11 ml. When the editing station 400 recognizes the specified position in this way, the message area 3
OK to 30 I PO3lTl'0NIs RECOG
NIZED'' 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 310 as shown in Figure 22-2. . In addition, if the operator instructs another command key after instructing the ``area specification'' key or the position specification key and before inputting coordinates, the coordinates of the area specification or position specification The input waiting state is released, and the command that was displayed before the "area designation" key or the "position designation key" was specified is displayed in the working area 310.

To release the editing station 400 from the control of the image processing unit IO and cancel the online state, input the KL command using the alphabet keys 223. At this time, the process proceeds to step S28 via step S25, and
KL'' character information is output to the image processing section 10 to request termination of the image editing program, and the process proceeds to step S27.In step S27, the editing station control section 450 outputs the editing program of the image processing section 10. If it is detected that the process has not been completed, a negative determination is made, the termination input is invalidated, and the process proceeds to step S7.Furthermore, if a positive determination is made in step S27, the online state is canceled and the process proceeds to step Sl. do.

Inputting a group of keys 228 related to application files;
That is, when there is an instruction using the ``Standard Work'' key, the ``Create Application File'' key, and the ``Create Application File'' key, the editing station 400 is moved in step S30 as shown in FIG.
is set to edit mode.

Here, the °°Create application file' key is a key used to instruct when creating a new application file, and the 'Call application file' key is used to call and modify an application file registered in the disk memory 90. This is a key for instructing when adding a file, and the "Standard job" key is a key for instructing when an application file is called up and the command string is sequentially transferred to the image processing section 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 changes the screen of the CRT 300 to blue, and displays the screen in the message area 340.
ENTERFILE NO, AND CARRIAGE
"RETURN" is displayed and the operator is requested to input the file number.Then, "EDIT MODE" is displayed.
Edit station 4 by displaying it in the mode display area 330
Informs the operator that 00 is in edit mode,
The screen of the CRT 300 is returned to black, and the following processes are executed in accordance with the respective processing procedures 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 enters the message area 340 in step S40.
TERMENU + ''' is displayed to prompt the operator to create an application file, and the cursor is moved to 30.
2 flashes in the upper left corner of the working area 310 and waits for command input, and then the operator inputs a desired command group in sequence to create the 1st edition east program. By inputting one command and adding a carriage return, the command is transferred to RAM 45B in editing station control section 450 and displayed in working area 310 at the same time. In this way, the input command group is stored on the RAM 458, so by instructing the screen editing key group 228, the screen editing function, that is, the cursor 3
02 blinking line or character, inserting a new line or character, moving the cursor 302, etc. can be executed. When the number of lines that can be accommodated in the working area 310 is exceeded by creating a new line in the editing program, the working area 310 is scrolled up line by line as in echo mode, and also by moving the cursor 302 up and down. The working area 310 is also 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 (
...) command, which is input next to the ADR (...) command coordinates x 0 and YO, so make sure that the 0 (...) command has been input in advance. Then, OR(...) is searched from the command group that has already been entered manually, and coordinate information XO, YO, Xi, and Yl of the same file number is extracted. 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 such coordinate information can be extracted, as shown in FIG. The area 314A determined by 1 is displayed in green, for example. Then, the left half of the working area 310 is made white, and the LO (...) command and the A! IR(
...) The area 314B defined by the coordinates xO' and YO' newly specified by the command is displayed in red.

Further, the file number FN of the image file is displayed at the upper right corner of both areas 314A and 314B.

If the new editing area created by XO', YO', X1O, 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 CRT30Q is set to white, for example, and the areas 318A 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 upper right corner of the area.The right side of the screen is colored blue, for example, and the area defined by the changed coordinate position information XO' and YO' and Xl and Yl is displayed on the right side of the screen. 318B
and 317B are displayed in green. Further, a rightward arrow 318 is displayed in the center of the screen to indicate movement of the image.

When the image file movement display is completed, the message area 340 displays 'END OF TRACE'.
MODE'' is displayed to inform the operator that the trace has ended.Then, when the operator points to a point d on the console unit 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 an application file, as mentioned above, the image file number, 1liil collection image area (XO, YO', Xi, Yl), lxA east image change position (XO', YO'), and number of prints are set numerically. In addition to specifying them in , you can create programs using them as variables to add flexibility to image editing.

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

In this way, when the operator creates an application program and the creation is completed, the operator inputs the editing end key in step S34. At this time, the process advances to step S35, and the editing station control unit 450 displays "5TORE THIS COMM" in the message area 340.
AND FILE? ” is displayed to confirm whether or not to register the application program stored in the RAM 4513 in the disk memory 80 as a file.

The operator denies this message.
When the ° key is pressed, a negative determination is made in step S3B, and the editing station 450 ends the edit mode, erases the screen 301, moves to step S37, and returns to the echo mode.

On the other hand, when the operator inputs the °°Y'° key to request file registration, an affirmative determination is made in step 53B, and the process advances to step S38.
Based on the file number set in step 32, the editing station control unit 450 sends an ED(...) command to the image processing unit IO to obtain permission for application file transfer. 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 5311 and the process advances to step S40, where the image processing unit 10 controls the editing stage overturn control unit 450. The file registration is permitted and the file transfer is executed.

When the file registration is completed, the process moves to step S37 and returns to the echo mode.0 The image processing unit IO informs the editing station control unit 450 that a file with the same file number as the created file has already been registered. If the signal has been transferred, step S39
An affirmative determination is made in step S41, and the message area 340 is filled with 1, for example, FILE ALREAD.

40°'ENTERFILE NO, ANDCARR
IAGE 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 image processing section 10 to the ED command is other than the error code "'08", the editing station control section 450 determines that it is impossible to transfer the application file, erases the screen 301, and shifts to the editing 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 S48, the image processing unit 1O calls the corresponding application file from the disk memory 80, and stores it in the RAM 45.

Reset to edit mode in step 7, then step S
33, the application file is corrected by deleting one line and characters and inserting a cap using the same procedure as for creating the application file. Note that 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 also displays a message in the message area 340 and status display area 360. Each,
To display an error code, an error message corresponding to the error code, and a status.

Next, the procedure for routine business input processing will be described. The operator is
When the user instructs the "Standard job" ° key and inputs the file number of the desired application file, the editing station control unit 450 stores the designated file in the RAM 45B as in the case of calling an application file (steps S32 and S45). ~547).And,
In step 848, the editing station control unit 450
The command group stored in AM45B 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 finds the variable N, displays a comment in the message area 340 of the CRT 300 asking for the input of the file number, and then replaces the variable N with the numerical value input 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 F is displayed.
are replaced with the values XO, YO, XI, and Yl input by the operator. Next, when variable P is discovered, message area 3

...) 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. 23-5 is performed.

The process shown in Figure 23-2 is performed. Further, when the variable S is found, a message area 340 displays a message 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 23-8 to change the editing form to the working area 310. message area 3 in step S52.
"OK?" is displayed at 40 to confirm with the operator whether the image editing format is as desired. If the operator denies the confirmation by instructing the II N 11 key, for example, the editing station control unit 450 controls the CRT 30.
0 screen is erased and the process moves to step S37. On the other hand, if the operator affirms this by instructing the "Y" key, for example, the process moves to step S53, and the editing station control unit 450 saves the screen as it is, and sequentially sends the command sequence 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
Editing station control unit 450 displays the command in status display area 380 to allow the operator to recognize the status of the system.

When the image processing section 10 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 executing a command by the image processing unit IO, the editing station control unit 450 interrupts the transmission of the command, erases the screen of the CRT 300, displays an error code in the message area 340, and sends an echo. Move to mode.

It should be noted that in the two series of editor i-mode processes, that is, command file creation, command file calling, and routine work, the operator must perform step S3.
3 or during the input process in step S50.
If the key is instructed, the screen of the CRT 300 is immediately erased, and step S3? to return to echo mode. Also, if there is an end input, it outputs a KL command to the image processing unit 10, and outputs a KL command to the image processing unit 10 and the editing station 4.

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, a system and an optical fiber network, and an optical fiber interface that performs mutual communication of image information between this system and other systems on the IIDX line network. Since the image processing apparatus of the present invention is constituted by a DDX interface that performs mutual communication of image information between the Short-distance communication of image information using a fiber network, 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 the image information within the device of the present invention and from other systems to the tree system via an optical fiber cable. By switching the flow of the image information being sent, it is possible to select one or more of the buffer 7 memory, optical fiber interface, and printer section and transfer it to each section. Copies can be processed in parallel, and image processing time can be shortened.

(3) Since the image information transferred from other systems on the DDX line network via the DDX line network and the DIIX interface is stored in the buffer memory, regarding the processing of the image information 11N stored in the buffer memory, ” The same effect as Section 1 (2) can be obtained.

(4) When communicating image information between this system and other systems via the D[] Signal R indicating that image information of the original 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 RDR, errors in the transmission direction can be prevented and D
It is possible to reduce the transmission time of image information using a DX line.

(5) The tlDX 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. In this case, the run length of 1947 minutes 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. When communicating using the DDX line,
Since the total number of lines of the original image to be transferred can be reduced and data compression can be performed efficiently, the transmission time can be shortened.

(6) When communicating image information between this system and another system via the RoroX network, the image processing control unit sends a signal CRQP to the DDK interface requesting connection to the other system; 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 NRYP indicating that the image processing control unit cannot transmit or receive image information within a predetermined time. The signals RDS and RDR, which respectively indicate that the DDX interface is ready, the signal RQS, which indicates that 1947 minutes of image information is being supplied to the DDX interface during the valid period, and the image information SOT are transferred. Also, DDX
The 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. Signal CND
, a signal M[lS indicating that the DDX interface is in a mode in which it can transmit image information to other systems, a signal NOR indicating that it is in a mode in which it can receive image information from other systems, and one line of image. A signal RQS requesting the transfer of information, a signal RVA requesting reception of 1947 minutes 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 signal 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 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 the optical signals transmitted from other systems on the optical fiber network to the right column into electrical signals, reproduces image recording commands and image information from the signals, and performs 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. 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 printer 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.

(lO) The image 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, making it easy to store and edit a large amount of image information. can be done.

(11) The image processing control section sends a scan start command to the league section, and the league section scans the original image in response to the command, and supplies image information to the image processing control section. , 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 league section is equipped with a league operation section, and the application file stored in the disk memory can be activated from the league operation section, so that routine work of image editing can be easily performed on the league section side as well.

(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, and in particular to other systems on the optical fiber network. In this case, since the number of copies can be specified for each destination, image information can be transmitted easily and quickly.

(14) The editing station is equipped with a command menu section where the operator inputs a group of commands for image editing, and a digitizer where the operator inputs the coordinates of the image to be edited, making it easy to input information for editing a single image. 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 with the station, you can easily edit images and create application files for image editing, and even if there is an error in input information, you can quickly deal with it. Editing can be done efficiently.

(16) The command menu section of the ml station has a command to start the league section, and the manual operation of that command allows the league section to perform the operation of reading the manuscript image. In cases where it is necessary to cause the section to perform a reading operation, such an 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, we have included a command to specify areas to be shaded and dithered in the image, which greatly increases image processing ability and makes the work easier. It can be done easily.

(18) The command menu section has a command to start the printer section, and by inputting that command, the printer section can be made to perform an image recording operation, so it is possible to make the printer section perform an image recording operation 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. (21) Since the area on the digitizer and the address of the buffer memory are made to correspond to each other, image editing can be performed easily, reliably, and quickly. can be done easily and without error.

(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 Users can also understand the operating procedures and perform image processing easily and quickly.

(23) When editing images, etc., if the image editing area specified by one 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 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 CR7 screen, the execution form can be visually checked, 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 an editing program, the number of recorded images, editing area, etc. can be entered as variables, making the system more flexible and making image editing easier. be able to.
