Abstract

PURPOSE:To make the gradation processing or the like of original pictures possible, by selecting a processing mode of picture information read from originals which are transmitted to an external device. CONSTITUTION:Original picture information read from a reader part 500 is converted to original picture digital information by a CCD driver 50 or the like of a picture processing control part 100 and is stored in a buffer memory 20 through an exchange 40. This information is transmitted to the external device through the exchange 40 by long-distance and short-distance communication devices formed with interfaces 60 and 70. In this case, an operation part interface 58 is operated in response to an operation part 550 of the reader part 500, and the driver 50 is controlled through a dither controller 54 by a CPU10 to select gradation or the like of transmission picture information. Thus, the gradation processing of original pictures can be performed also in the picture processing device where picture processings and short-distance and long-distance communications of picture information are performed easily and quickly.

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, 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 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 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 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.

the purpose The object of the invention is to eliminate the above-mentioned problems.

An object of the present invention is to provide an image processing device that can easily and quickly perform image processing such as image editing, and short-distance and long-distance communication of image information at 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 30 and internal bus 80-5 via 115 and 80-118, and receives and passes address information and data information to and from these buses.

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

80-6 is a clock generator, which generates a clock signal of a predetermined frequency based on the reference oscillation output from an external crystal oscillator, etc., through the signal line 8'O-120.

-7, and via signal line 80-121 to I10 processor 80-1. An initial reset signal at power-on and a manual reset signal are output to bus arbiter 80-2 and bus controller 80-3. Further, the clock generator 80-4 is connected to the MWT from the multipath 30 via the signal line 80-122.
Upon receiving the transfer acknowledge (XACK) signal as a recognition response to the C signal and the MRDC signal, it is determined whether the multipath 30 enters the wait state and whether the wait state is released. A has-ready signal is output to I10 processor 80-1 via line 80-123.

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 80-10 via the signal line 80-125. By generating this signal and supplying this signal to clock generator 80-6 via signal line 80-128, I10 processor 80-1 can proceed to the next operation.

ROM 80-8 stores a microprogram for I10 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 I10 processor 80-1 fetches the microprogram stored in the ROM 80-8. And the signal leading to ROM80-8! JX80-131 is a data signal line for the fetched instruction code.

The address decoder 80-10 selects the ROM 80 based on the chip selection signal of the I10 processor 80-1 supplied via the internal bus 80-5 and the signal line 80-135.
-8 selection signal 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 8O
The signal line 80-113 leading to -1o transmits the S2 signal, which is a type of status information. That is, the S2 signal is a signal for identifying whether the address information latched in the address/data buffer block 80-4 is address information for the internal bus 80-5 or for the multipath 30, address decoder 8
O-1o performs the 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. ■10 When the processor 80-1 outputs address information to the address/data buffer 80-4, the bus controller 80-3 outputs the address/data buffer γ80-4.
When the ALE signal is supplied to address/data buffer 80-4, address/data buffer 80-4 latches address information into the address buffer. Also, after the latch, the bus arbiter 80
-2 acquires the right to use the multipath 30, the bus arbiter 80-2 supplies the AEN signal to the address/data buffer 80-4, and
o-4 transfers the latched address information to multipath 30
Output to. Here, if the DMA controller 80 is in write mode and the multipath 30 has been acquired,
I10 processor 80-1 outputs data information to address/data buffer 80-4, and address/data buffer 80-4 outputs data information to bus controller 80.
Upon receiving the DEN signal from -3, it outputs data information to multipath 30. On the other hand, the DMA controller 8
0 is in read mode, the address/data buffer γ
80-4 reads data information on multipath 30 and provides the data information to I10 processor 80-1. I
The I10 processor 80-1 reads data information from the disk memory 90, which is the data transfer destination.
This is done by confirming the XACK signal sent to the processor 80-1.

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

As the disk memory 90, for example, the power source 3 ([
Use was-to of e. The disk memory 80 has an internal disk controller circuit (not shown), and this circuit is connected to an internal bus 80-5 of the DMA controller 80 via a data bus 80-140, and also has signal lines 80-142 and 80-143, respectively.

The data bus 8O-141) transmits command information, result information, data information, and status information, and one address is collectively determined for the former three pieces of information to form a set of information. They are distinguished by being sequentially input and output to the disk controller circuit. 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 80, and the result information is information that specifies the address and number of bytes on the disk memory 80.
This information indicates the result of checking for errors when transferring information between.

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

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

memory space.

The bank space of the buffer memory is from address 100OOH to E.
Although it has a capacity of 898 kilobytes up to address FFFFH, as mentioned above, the storage capacity of the buffer memory circuit block 20 is 1985840 bytes, and it is not possible to store all of it in the punctured space of the buffer memory. The buffer memory space is then divided into three banks: puncture 0. It is divided into bank 1 and bank 2, and is connected from the CPU circuit block 10 to the signal line 132 (Fig. 4 and 6-2).
The bank is switched by the puncture switching even signal outputted through the puncture switch (see figure), and the specified bank can be allocated 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.

The communication program space uses 8 kilobytes of the RAM (32 kilobytes) 10-3 in the CPU circuit block 10. In addition, the work RAM space is
32KB RA old 0 in CPU circuit block IO
Use 24 kilobytes, which is obtained by subtracting 8 kilobytes used for the communication program from -3.

FIG. 8-1 shows the inside of the buffer memory circuit block 20.
3 shows an address map of rough memory 22. This buffer memory 22 is A4 size (29mm x 210mm)
) has the ability to store information decomposed into 18 pixels per 1 mm. The league unit 500 main scans the A4 size document in the vertical direction (2i37mm direction), and then CC: D570.58 (l and 590 are 1 mm per 1 mm).
The image is divided into 8 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 (210 mm direction) and C
CD570, 580 and 590 also have 1+n in this direction.
Since 16 lines are scanned per m, the document is scanned 3 times in the width direction.
360 lines are scanned. Therefore, an A4 size document is 1588B? It is divided into 20 pixels, and the image processing control unit 100 stores 33 4752-bit pixels in series.
Supplied 60 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 18 lines of 16-bit image information, that is, 256-bit image information.
If 6 bits are one word and one address is given to the l 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 scanned first
52-bit serial image information is 1 mm in the vertical direction of the document.
The first 1θ bit pixel group transferred is at address 0OOOOOH of the buffer memory 22, and the next 16 bit pixel group is 0OOj9H. Similarly, pixel groups of 16 bits each are successively 1B (IOH) addresses, 00020H address.

t) 0030H address..., 01280H address, etc. are stored.

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, when outputting image information from the buffer memory 22 to the printer section 600, it is read out every 16 addresses starting from the initially set address, similarly to when storing the image information.

Next, the 4752-bit image information for the second line is processed from address 0OOOIH to 01 in the same way as for the first line.
281) Stored up to address 1. In this way, the first
Line 1536 (88mm in the width direction) from the line to the 1536th line from 000 (10) 1 to 8F5F
F) Store at address 1, and make this address space bank 0 on the buffer memory 22.

Next, 1 from the 1537th line to the 3072nd line
Make line 536 the same as bank 0? It is stored from addresses 0000H to DF5FFH, and this address space is designated as bank 1 on the buffer memory 22. Furthermore, the 307th
288 lines from line 3 to line 3360 are stored from address EOOOO)1 to address F4EIFH, and this address space is stored in bank 2 on buffer memory 22.
shall be.

As described above, if the method of storing one word of image information with one address attached is used, the entire area of an A4-sized document can be stored at consecutive addresses on the buffer memory 22 using a 1 mm x 1 mm square as a unit block. can be stored. As a result, when the operator specifies the image processing area in units of ■ using the console unit 200, when registering the specified area in the disk memory 90, all that is required is to set the start address and end address of the specified area. One 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, image information of 18 main scanning lines (1 mm width) can be transferred to D.
Since MA transfer is performed, 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 20+nm, the CPU circuit block 10 only needs to set the address 20 times.

Further, since the address corresponds to the position on the document image in ml11 units, when editing the image, the operator can simply specify the position on the document in mm units, which is convenient. Note that in this example, since CCDs 5?0.580 and 590, which have a reading capacity of 16 bits per mm, were used, it was decided that 1 address corresponds to 18 bits in the vertical direction, but the number of bits corresponding to 1 address is is that CCD
5?0.580 and 590, other numerical values may be used, and it goes without saying that the same effect can be obtained even if the address is set in units other than mm, for example, units of inches.

Figure 9-2 shows the flow from the multipath 30 to the buffer memory 2.
The address map when looking at 2 is shown. 0 in Figure 9-1
The address space from addresses OOOOH to 6F5FFH is bank 0, the address space from addresses 700008-OF5FFH is bank 1, and the address space EOOOOH-F4EIF) is bank 2, and these spaces are respectively 100OOH to EEBFE) as shown in Figure 8. No. 1, 100OO

Make it correspond to the address space of address 1. The multipath 30 has an 18-bit data bus and a 20-bit address bus, but the area that can be accessed by this multipath 30 is 1 megabyte. In other words, 8-bit data is
06 bits can be accessed, and when accessing 16-bit data, it will span two addresses.
In this case, as shown in Figure 8-2, every other consecutive address is assigned to the 16-bit data, and the 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 figure g9-1, when accessing the buffer memory 22 from the multipath 30,
As described above, the address converter 21-28 in the buffer memory circuit block 20 converts the address in FIG. 8-2 to the address in FIG. 9-1. The 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 80. Reference numeral 91 denotes a drive, which is numbered ○, l, . . . corresponding to the number of disk devices. In this embodiment, only one disk device, that is, a drive numbered 0, is used. The drive 91 has three heads 82, and each head 92 has 354 tracks 93.
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 FIG. 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=3. X T, N+ HN (however, HN=0~
2, TN=O~353) (1) That is, when a certain sequence number SN is determined, the track number TN and head number HN are determined correspondingly, and the addresses of the head 82 and track 83 to be accessed next are determined from the previous one. Sequence number that is the sequence number SN defined in 1 plus 1! These are the head number and track number obtained corresponding to 1liN+1. The sectors 84 in the track 93 are accessed in ascending order of sector numbers SC; TH.

FIG. 1O-2 shows an index table provided in a predetermined area within the disk memory 80, and the use status of the disk memory 80 is managed by this index table. In this embodiment, the area is head number HN=0. Of the sectors 94 with track number TN=0, sectors with sector numbers 5CTN=0 to 13 are used as the index table area, and in particular, sectors with sector numbers 5CTN=0 to 8 are used as the disk memory
0, and sector number 5CTN=
Allocate sectors 9 to 13 to the file index table for file management. Sector number 5CTN=0-1
Sector No. 3 is written to addresses 8000H to 78FFH in the fixed area of RAM 10-3 by a program (oven program) that reads the index table into RAM 10-3 in the CPU circuit block 10, and undergoes a predetermined operation. The fixed area of RA old 0-3 is written to the disk memory 80 again by a program (close program) that stores it in the disk memory 80.

As shown in Figure 10-3, the sector bit map table has the area 94A divided into 1062 4 bits from 5N=O to 5N=1061 in ascending order of sequence number SiN.
It is divided into byte blocks, and each block stores data indicating the usage status of one track, that is, 18 sectors, with one bit allocated to each sector. As data indicating the usage status of a sector, for example, if a certain sector is in use, ``''loo is stored in the sector bit corresponding to that sector, and if it is unused, 0° is stored.

When registering a new data file in the disk memory 90, find an area where the number of consecutive sectors necessary for registration are empty, set the sequence number SN and sector number 5CTN corresponding to that area, "°1" is stored in the sector bit corresponding to that sector. Conversely, when deleting a data file, "O11" is stored in the sector bit indicating the corresponding area. However, in the bit corresponding to the index table, that is, block 0,

) 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.

The file index block FITI consists of four blocks of 2 bytes each, numbered 8 (status A, WAX block, 1 block size, and 8), and is provided at the time of initialization of the disk memory 80 to store the entire file index table. Remember about usage status. Status A is an area used for system expansion, and is left unused in this embodiment. The WAX 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 (3
2H). The l block size indicates the length of the index of various data related to the file per l file, and in this embodiment, the length is 38 (28H) bytes as described below. The current B number stores the number of files registered in the disk memory 90, and when a new file is registered, it is compared with the number stored in the WAX size and if the number does not exceed that number. New registration is performed by adding 1, and if the number exceeds the MAX size, no addition is made and new registration is not accepted. On the other hand, the already registered 1
When deleting one file, the number stored in the current B number is decremented by 1, and the file is deleted from the disk memory 80.

FIT2 and FIT3 indicate file index blocks for file type 0 and file type 2, respectively, and each stores 38 bytes of data. In FIT2 and FIT3,
R9V is a 2-byte area used for system expansion.
It is not used 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 90. The file type is a 2-byte area in which data of the above file type °°O°" or °2" is written.The bank and address in FIT3 are the R
These are 2-byte and 4-byte areas, respectively, which indicate the banks and addresses of A old 0-3, and are used when allocating application files to RAM 10-3. The byte count is an 8-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.

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

This is a 2-byte area each for storing 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 °°0°, coordinate data indicating where on the copy paper the image information of the area to be edited is placed is stored. As shown in FIG. 1O-5, XO, YO, Xi, and Yl are calculated by placing the manuscript on the manuscript placement section 240, and then selecting the point A on the editing area (hatched) closest to the 0 point and the closest point from the 0 point. By pointing the far point B using the stylus pen 280, the coordinates xO and YO of point A and the vertical length XI and horizontal length Yl of the editing area are determined, and these values are stored in hexadecimal. Ru. File type 2
In this case, as shown in FIT3, XO, Y of FIT2
The areas corresponding to O, Xi and Yl are unused areas.

When transferring a certain image data file from the disk memory 80 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 XO, YO, Xi image information of that block is DMA transferred into the corresponding area of the buffer memory 22.

Also, when changing the position of the editing area on the copy paper,
Since Xt and Yl are 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 80 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 Ml encoding and MR encoding of image information using this system and transmitting it to other systems is
According to Recommendation 7.4 of T.T., 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
87 mm direction) is one line, and the resolution is 16 bits/ml1, so the maximum run length, that is, the run length when one line is all white or all black, is 4752, which is expanded. Exceeds the maximum expression range of Ml code 2B23 (=2580+63).

(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, after the first line transferred to the DDX interface 60 is M)I encoded, the remaining 3358 lines are MR encoded.

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

Regarding point (2), the reason why the parameter K is set to infinity is to save the time it takes to repeat the encoding with a small finite number (M each time as IN), and the parameter K is set to infinity. The reason why it can be set to large is that the image information to be transmitted has already been binarized by the COD driver 50,
It is 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.

t-t-, one line of image information (4752 bits) transferred from the buffer memory 22 via the signal line 137 is transferred to the line via the data/clock interface 60-1 and the write switch 60-3. buffer 60
-4.80-5 or 60-8. This image information is transferred to a line buffer 60-4,80-5 or
-6. That is, the transfer time for one line of image information is 475.2 ps. The image information of the first line that is transferred first is first applied to the line buffer 80-4 by the switch 60-3, and the line buffer 60-4 transfers the image information of the first line. When the storage is completed, the switch 80-7 opens the gate of the line buffer 60-4, closes the gates of the line buffers 60-5 and 60-6, and transfers the stored image information to the RL counter 60.
-80-8, the white and black run lengths of the information are counted, and the run-length coded first line image information is converted into an MH code by an RLMMH/MR converter 80-10. be done. While the line buffer 60-4 is outputting image information, the switch 60-4
-3 closes the gates to line packs 760-4 and 60-6, 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 RLjE/inverse counter 60-7 by the switch 60-7, and the relative pixel change from the first line is The positions are counted and RL4+
MR encoding is performed by the MH/MR converter 80-10.

The image information of the third line transferred to the line 7 person transfer 60-8 is also processed in the same way as the second line.
The image information output from the line buffers 80-4, 80-5 and 60-6 is RLiF, /adic counter 60-
7, and is supplied to an RLHMH/MR converter 80-10, where it is MR encoded.

Next, the run-length encoded image information supplied to the RL→MH/MR converter 80-10 is 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) When run length RL<25130, normal M
Represented by H symbol. 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 in the following (a) and (b).

(a) 2560≦RL≦2823=2580+8
Case 3 (7) As in case (1), it is represented by one make-up code (in this case, a make-up code of 2580) and one terminating code.

(b) 21 (If 23<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, ( In case 2), the 2560 make-up code is immediately followed by a terminating code of the same color (a), and the 2560 make-up code is followed by another make-up code of the same color, followed by a terminating code. There is a subsequent case (b).A processing example for case (2) is shown below.The underlined numerical values are the added makeup codes.

Example: 2580 = 2580 + 0 2581 = 258 (DI 2 + 323 = 2580 + 83 2824 = 2560 ÷ 64 104289 25EiO + 1728 + 1 4752 = 2560 + 2178 + 18 Next, Figure 11 (A), (B) and (C), and Figure 12-1 The meaning of each signal flowing along the signal line interconnecting the image processing unit IO and the DDX interface 80 shown in FIG. 1 will be explained.

Figure 12-2 shows each signal, its name, image processing unit 10 and D
8 is a diagram showing the direction (arrow) of signals between the DX interface 80 and the DX interface 80. FIG. Here, FC and SG are respectively,
This is a safety ground wire and a signal ground wire.

The call request signal (CRQP) is processed by the image processing unit 10 using DDX.
This signal requests the interface 60 to connect (call) with another system, and this signal is a connection raw signal (CN
D) is energized and deenergized at the same time, and when the connection failure signal (NRYD) is energized, it is treated as invalid. The paging signal (arp) is a signal that the DDX interface 60 indicates to the image processing unit 10 that a call has arrived from another system, and the processing for CNII and NRYD is similar to CRQP.

The dialed number signal (IILN) 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 from which the image processing unit IO requests the DDX interface 60 to connect to the DIIX 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, C
NQ is energized, and de-energizing CNQ disconnects the line.

The non-receivable signal (NRYP) is activated when the image processing unit 10 cannot be in a state where it can transmit or receive within 6 seconds. NRYII indicates that one 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. Further, if the CHD 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 caused by the activation of CRQP or CIP and the activation of CNQ, which causes the communication between this system and another system (other station) to be communicated with.
It is activated when the communication conditions are established, indicating that the line connection has been completed and the system is ready for communication. CND is de-energized when CNQ is de-energized or when the other station disconnects the line. Clear to send signal (RD!1
li) and a ready-to-receive signal (RDR) indicate that the image processing unit 1θ can be in a state where it can transmit and receive image information for one A4 size document within 6 seconds, and the CNQ activation signal At the same time, RDS or RDR is activated.

Transmission mode signal (MI]S) and reception mode signal (M
RR) indicates that the system is set to a mode of transmitting and receiving image information, respectively, and these modes are RDS and R[) of both the calling and called parties.
Determined by looking at R. It is also possible to perform reception or transmission immediately after completion of transmission or reception, respectively.

A ready-to-transfer signal (RDT) is asserted within 6 seconds after the MDS or MDR is asserted to indicate that image information can be transferred in transmit or receive mode.

The transmission data request signal (RQS) is energized and deenergized at regular intervals, and the DDX interface 6o requests the image processing unit 10 to transfer 1547 minutes 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 (
RQS is deenergized upon completion of the transfer. The RQS repetition period is set longer than the minimum transmission time. SVA is energized according to RQS and SOT
This indicates that sampling is allowed in synchronization with the transmission clock (SCK), and the power is reduced when the transfer of 5LIT is completed. The RVA is energized at regular intervals, and the DDX interface 8o requests reception of 1547 minutes of decompressed image information (RDT) received from another system.
Indicates that DT is allowed to be sampled in synchronization with the reception clock (RCK). The repetition period of RVA is similar to RQS.

SDT and RDT represent the binary transmitted and received image information in black and white, SCK and RCK, respectively.
are the sampling clocks of SDT and R1)T, respectively.

In the device ξ of the present invention, when transmitting between this system and another system on the DDX line 800, the transmission direction is the calling side system (calling side station) and the called side system. (Called station) compares RDS and RDR and makes a decision as shown in Figure 12-3, thereby preventing errors in the transmission direction.

That is, in Fig. 12-3, as shown by ○ for the listening state, arrows for the transmission direction, and X for the reduced power state and the transmission disabled state, only the RDR on the calling side and at least the RDS on the called side are shown. 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 party's RDS and the called party's (74) at least RDR are activated, and.

RDS and RDR of the calling party and at least RD of the called party
When R is activated, the direction of transmission 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 mentioned above.

FIG. 12-4 shows an example of a procedure for transmitting data between a calling station and a called station. Here, ID
S is a transmission capability identification signal, which identifies the transmission capabilities of the calling and called stations, i.e., RDS and R
This is a signal that mutually informs each other of DR. For example, the transmission format is OQ 00 RDS RI)
The 8 bits of "R10" will be sent sequentially from the most significant bit to the least significant bit, and both stations will transmit the RDS and RDR of this system and the RDS and RII of the other station.
From R, the transmission direction is determined as shown in FIGS.

RDY is a transmission preparation completion signal, and its transmission format is, for example, "00010010" (75), which is sent in the same way as in the case of IDS. Indicates that preparations for transmitting and receiving image information for one image have been completed.

and the old one is MH encoded first line image information, MR2
~MRn+1 (+≦n≦3380) is MR encoded image information of the 2nd to n+1th lines, MHn is MH encoded image information of the nth line, and MRn+1
~MR3380 is the Ml'l coded n+1st to 3rd
360 lines of image information, MHI-MR33
80 indicates image information 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 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.

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 each other of line disconnection.

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

In the transmission of 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 the 1st line to the 3360th line of the n-th line, and transmits the same.

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.

As a result, if the transmitted and incoming VIDEO signal is identified as command information, the command/image identification circuit 70-3 generates a command recognition (CACK) signal and during the command reception period. During this period, this signal is passed through the signal line 70-103 to the AND gates 70-4 and 70-4.

At this time, since the VIDEO signal and the CLK signal have already been input to AND gates 70-4 and 70-5 via signal lines 70-101 and 70-102, respectively, CA c K (input of No. 8 Accordingly, AND gates 70-4 and 70-5 supply a command signal and a clock signal to all reception command registers 70-10.

When the command reception is completed and the CACK signal is de-energized,
At that point, an interrupt is applied to the CPU circuit block 10, and the CPU circuit block 10 supplies an address designation signal (ADR signal) to the reception command register 70-10 via the signal line 13B-1 and the address decoder 70-11. What is the receive command register? 0-1'O address, and further sends an I10 read command (Ilo

(6) Image editing method Image editing is performed by appropriately performing DMA transfer between the buffer memory 22 and the disk memory 80. That is,
The image information for one A4 size document read by the league unit 500 is stored in a predetermined address of the buffer memory 20, and a part of the image information is transferred to the DMA controller I/roller 80.
The data is stored in the disk memory 80 via the . Therefore, by erasing the buffer memory 22, restoring the image information previously stored in the disk memory 80 to the desired address space of the buffer memory 22, and copying the image data in the printer section 600, unnecessary parts of the original can be removed. You can obtain 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 80 and stored therein is defined as an application file. Further, image information stored in the disk memory 80 is defined as an image file. When registering these files in the disk memory 80, as described above, 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.

16(A), (B), and (C) show an example of simple image editing. First, the first autumn manuscript Ll shown in FIG. 16(A) is read by the league unit 500, and its image information is is stored in the buffer memory 22. By specifying point A and point B using the document placement section 240 and the stylus pair 280,
Image information within the range of Ml is extracted from the stored image information, and the image information is stored as the old image information, for example.

Disk memory 90 with file number °°01°
Register. Similarly, for the second autumn manuscript L2,
As shown in FIG. 9B, the image information M2 extracted by specifying the 0 point and the D point is registered in the 0-order buffer memory with a file number '02°° added to the disk memory 90. 22, specify the E point and F point, and set the file numbers ``01'' and '' as shown in the same figure (C).
The image information in the areas Ml and M2 stored in the image file 02'' is transferred to the address space corresponding to the areas Nl and N2 of the buffer memory 22, respectively. Image information for one document is stored 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, 3) Editing procedure Figures 18, 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, the display division of the CRT 300 screen and initialization of system constants are performed. The CRT 300 has a screen 301 that can display 40 horizontal characters and 24 vertical lines. No. 22-1
The figure shows an example of display division of the screen 301, where the first
A working area 310 from line 1 to line 18 is used to display characters transferred from the image processing unit 10 to the editing station 400. 320 on the 20th line is a blank area, and no display is made in this area, making the boundaries between the working area 310 and the following areas clear to the operator. 330 on the 21st line is a mode display area, which displays in which mode (described later) the operator is using the editing station 400. 340 on the 22nd line is a message area, in which the editing station control unit 450 displays to the operator commands and parameters to be input next, error codes, etc.

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

360 on the 24th line is a status display area, which is an area for displaying the status of the image processing unit 10 to notify the operator.

As other initialization, when a command is input, the command echoed back from the image processing 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 when the command is displayed from the 1st line to the 18th line, the working area 310 is scrolled up one by one, 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 requests, i.e. “REQUES”
T ``as a message to accept the key'' NOT RE
ADY, ENTER REQUEST KEY" is displayed, and the process waits for the input of the 'REQUEST' key in step S2.

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

Edit mode creates application files,
This is a mode in which correction and execution commands are given to the image processing unit 10. In this mode, the character input by the operator is
First, it is temporarily stored in the RAM 45B in the editing station control section 450, and after being arbitrarily modified by the operator on the CRT 300, it is transferred to the image processing section 10. In addition, in the edit mode, the image processing section 1
The period during which the application file transferred to the editing station control section 450 via the editing station control section 450 is received is particularly referred to as the command mode.

FIG. 21 shows the operation of the editing station control section 450 when there is key human power in each mode. First, the mode is determined in step SA, and if it is determined that the mode is echo mode, the process proceeds to step SH, where the character echoed back from the image processing section 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 advances to step SC, and since the working area 310 is being used by the screen editor in this mode, the character is transferred to the user input area 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 judgment is affirmative, the process moves to step SF, sets the reception completion flag of the application file, and moves to step SG61)-0. On the other hand, if the judgment is negative, the process moves to step SE, where the received application file is transferred. The characters are sequentially stored in the RAM 45B, and the process moves to step SG.

By instructing the "REQUEST" key, the process advances to step S3, the editing station 400 is set to echo mode, and the image processing section 10 is sent an image (1) in step S4.
04) Output a start request signal for the image editing program. Next, in step S5, the startup of the image editing program is confirmed,
If the determination is negative here, the process proceeds to step S4, and if the determination is affirmative, the process proceeds to step S8. In step S6, C
For example, the screen of the RT 300 is made entirely black, and the message area 340 displays "0N-LINE" in green letters to notify the operator that the WA collection program activation request has become valid; Mode display area 330
displays “ECHOMODE” to indicate that the editing station 400 operates in echo mode;
A command input is awaited in step S7.

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

In the echo mode, 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 editing 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 S16 via step S15.
The input command is transferred to the image processing unit 1°, and the system operates according to the command. For example, the second
As shown in Figure 3-2, when you press the “RE” key, screen 3 appears.
The characters "RE'" are displayed at 01, and by instructing the carriage return key 225, a league drive signal is supplied to the league unit 500, and the document 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 the ``area specification'' key is specified, a message such as ``EN'' appears in the message area 340.
TERTOP RIGHTPO9ITION'' is displayed, and the left half of the working area 310171 is shown in white to prompt the operator to point A (see Figure 10-5), and the left half of the working area 310 is shown in white. An image information editing 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. Furthermore, the X and Y coordinates of point A, that is, xO and YO, are displayed in mm units on the user input canister 350. Next, in the message area 330, press “ENTER”.
"BOTTOM LEFT POSITION" is displayed to prompt the operator to input point B. When point B is input,
In step S21, the vertical and horizontal lengths x 1 and Yl of the edited image are calculated from the coordinates of point B and point A, and then in step S22, the editing area specified by inputting point A and point B is calculated. is displayed in the corresponding area 313 on the image editing area 311 in red, for example, as shown in Figure 22-4. At the same time, the message area 330
'OK! AREA IS RECOGNIZED'
” is displayed to inform the operator that the editing area has been specified, 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 5IEi, and these numerical values are transferred to the image processing section IO.

Also, when editing an image by specifying a position, specify the "position specification" key. In this case, specify only one point, that is, point A in the case of area specification. When input, for example, the coordinate display line 312 is displayed in red, and xO and YO are displayed in the user input canister 350.
Display in meters. Edit station 400 like this
When it recognizes the specified position, '' appears in the message area 330.
OK j PO3ITIONISRECOGNIZED
” is displayed to notify the operator that the coordinates have been validly input, and the numerical information of x0 and YO is transferred to the image processing unit IO.

When the area specification or position specification is completed, the process returns to step S7, and the editing station 400 returns to the console 1. l1
200, 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. do. Also, the state from when you specify the ``area specification'' key or ゛position specification °° key to when you input coordinates is canceled S, and before you specify the °°target area specification'' key or the °゛position specification key. The displayed command is displayed in the working area 310.

To release the editing stage 3 400 from the control of the image processing unit 10 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 1o 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 moves to step S7.Furthermore, if a constant appearance determination is made in step S2?, the online state is canceled and the process returns to step St. to move to.

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 400 performs editing in step S30, as shown in FIG. mode is set.

Here, the ``Create Application File'' key is a key used to instruct when creating a new application file, and the ``Create Application File'' key is used to call and modify an application file registered in the disk memory 80. This is a key used to instruct when adding a ``regular task'' key, and the ``regular work'' key is a key used to instruct when an application file is called up and the command sequence is sequentially transferred to the image processing unit 10 for image editing. .

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

Specifying the file number is essential. Therefore, in any case, in step S32, the editing station control unit 450 makes the screen of the CRT 300 blue, for example, and displays the message area 340 with 'ENTER FILE'.
"NO, AND CARRIAGE RETURN" is displayed and the operator is requested to input the file number.Then, "EDIT MODE" is displayed and the mode display area 33 is displayed.
0 to inform the operator that the editing station 400 is in the edit mode, the screen of the CRT 300 returns to black, and in each case, the following processing is executed according to the respective processing procedure.

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 'ENT' in the message area 340 in step S40.
ERMENU! ” is displayed to prompt the operator to create an application file. The cursor 302 is then blinked in the upper left corner of the working area 310 to wait for command input, and the operator then inputs the desired command group in sequence. By inputting one command and adding a carriage return, the command is transferred to the RAM 458 in the editing station control section 450 and simultaneously displayed in the working area 310. In this way, the input command group is stored on the RAM 4513, so by instructing the screen editing key group 229, the screen editing function, that is, the cursor 30
2, the blinking line or character can be deleted, a new line or character can be inserted, and the cursor 302 can be moved. By creating a new line in the editing program,
If the number of rows that can be accommodated in the working area 310 is exceeded, the working area 310 will be
In addition to scrolling up line by line, working area 310 is also scrolled up and down by moving cursor 302 up and down.

When creating an application file, area designation input processing is executed in the same way as in the echo mode, but position designation input processing is performed as follows. The position specification input when creating an application file is LO (
Since this is related to inputting the coordinates XO and YO of the ADR (...) command that is input next to the ...) command, make sure that the 1,0 (...) command has been input in advance. Then, CR(...) 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 the coordinate information can be extracted, the 22-5
As shown in the figure, the right half of the working area 310 is
For example, the area 314A defined by XO, YO, Xl, and Yl is displayed in green, for example, in white. Then, the left half of the working area 310 is made white, and the LO (...) command and ADR (
...) Coordinates newly specified by the command XO'
and YO' is displayed in red. Furthermore, the file number FN of the image file is displayed between the upper right portions of both areas 314A and 314B.

Note that if the new editing area formed by XO', YO', XI, and Yl exceeds the editable area, the inputs of XO' and YO' are invalidated, and new effective manpower is awaited. The edited image area displayed by inputting the coordinate information is erased by the manual 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 Figure 23-6, the left side of the screen of the CRT 300 is set to white, and the areas 316A and 317A determined from the coordinate information XO, YO, Xi, and Yl within that screen are set to red. and furthermore,
The file number FN of the image file is displayed in the upper right corner of the area. On the right side of the screen, this is colored, for example, in blue, and a rightward arrow 318 is displayed in the center of the changed coordinate plane to indicate the movement of the image.

When the image file movement display is completed, the message area 340 displays 'END OF TRACE'.
MODE" is displayed to notify the operator of the end of tracing. 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 an application file, as mentioned above, image file number 9 is used for image area (XO, Y).
O, XI, Yl), change position of i collection image (XO',
YO') and the number of prints by numerical value,
By creating a program using these variables, it is possible to add flexibility to five-image editing.

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

(+) RE (CR) The reader section 500 reads the document and stores it in the buffer memory 2.

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.
ANII FILE? ” is displayed to confirm whether or not to register the application program stored in the RAM 45B in the disk memory 90 as a file.

When the operator denies this message and inputs the ``N°'' key, a negative determination is made in step S38, and the editing station 450 exits the edit mode, erases the screen 301, and proceeds to step S37. Return to echo mode.

In response, the operator inputs the °Y" key to save the file D.
When B is requested, an affirmative determination is made in step 83B, and the process proceeds to step S38, where the operator has previously requested step S32.
Based on the file number set in , the editing station control unit 450 sends an ED(...) command to the image processing unit 10 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 90, a negative determination is made in step S39, and step S
Proceeding to step 40, 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 indicating that a file with the same file number as the created file has already been registered is transferred from the image processing unit 10 to the editing station control unit 450, step S38
If an affirmative determination is made in step S41, the message area 340 is filled with, for example, "FILE ALREA".

AGE 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 unit 10 to the ED command is other than the error code '08', the editing station control unit 450 determines that it is impossible to transfer the application file, erases the screen 301, and shifts to echo mode. At the same time, a corresponding error code is displayed in the message area 340.

Next, the processing procedure when 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 the 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 S4B, the image processing unit IO calls the corresponding application file from the disk memory 80, and stores it in the RAM 45.

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.

In this way, 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 23-6 to process the editing form. is displayed in the area 310-L, and then displayed in the message area 340 in step S52. ” is displayed, and the operator confirms whether or not the edited form of picture 1 is as desired. If the operator, for example, instructs the “N” key to deny the confirmation, The editing station control unit 450 is a CRT30
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 353, 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 in the status display area 380 so that the operator can recognize the status of this system. let

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

In addition, the processing in the two series of edit modes, that is,
In the process of command file creation, command file calling, and routine work, the operator performs step S33.
Alternatively, if the edit reset key is instructed during the input processing in step S50, the screen of the CRT 300 is immediately erased, and step S3? to return to echo mode. Also, if there is an end input, a KL command is output to the image processing section 10, and the image processing section 10 and editing station 400
The online state is canceled and the process moves to step S2.

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; Since the image processing apparatus of the present invention is constituted by 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 used 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 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 to the buffer memory, optical fiber interface, and printer section, it is now possible to select one or more of them and transfer it to each section. can be processed in parallel, and the image processing time can be shortened.

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

C4) When communicating image information between this system and other systems via the IIDX line network, image information of a document of a predetermined size must be transmitted between this system and the other system within a predetermined time. A signal R indicating that it is possible to transmit
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 with RDR, it is possible to prevent errors in the transmission direction, and it is possible to shorten the transmission time of image information using a DDX line.

(5) The DDX interface performs run-length encoding on one line of image information in the vertical direction of the original image, and then performs data compression on the run-length encoded 1947 minutes of image information using a two-dimensional encoding method. When the run length length of image information for one line exceeds 2623, one make-up code corresponding to the required run-length length is added following the make-up code corresponding to the run-length length 2560, and then , data compression is performed by adding one terminating code, so when communicating using the D[lX 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 the tree system and other systems via the DDX line network, the image processing control unit sends a signal CRQP requesting connection to the other system to the DDX interface and the DDX line. a signal CNQ requesting capture of image information; a signal NRYP indicating that the image processing control unit cannot be in a state where it can transmit or receive image information within a predetermined time; The signals RDS and RDR, which respectively indicate that 1947 minutes of image information is to be supplied to the DDX interface, and the signal RQS which indicates that the period is valid for supplying 1947 minutes of image information to the DDX interface, and image information SDT are transferred. Also, DDX
The interface sends to the image processing control unit a signal CIP indicating that a call has arrived 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 CHD
, a signal MDS indicating that the DDX interface is in a mode in which it can send image information to other systems, and a signal M[lR, indicating that it is in a mode in which it can receive image information from other systems, and an image for one line. A signal RQS requesting the transfer of information+, th, a signal RVA requesting reception of 1947 minutes of image information received and demodulated by the DDK interface from another system, and an image information received and demodulated from the other system are transferred. do. These communication suspension groups allow reliable communication of image information between this system and other systems.

Near) DDX When communicating image information via the @ line, once the relationship between this system and another system is determined between the calling system and the called 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 incoming line. If the called system detects a transmission error, it sends a message to the calling system.
Requests retransmission of 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, reproduces image recording commands and image information from the signals, and controls image processing. In addition, the commands and image information related to image recording for other systems that are transferred from the image processing control unit are converted into optical signals and output to the optical fiber network, so that the side that performs image recording In this system, image information can be recorded without requiring any operation, and image processing can be performed at high speed.

(8) The image processing unit (CPU circuit block) sends a status request I to the printer unit, and the printer unit responds to the status request by notifying the image management unit of the status of the printer unit and processing one image. The processing unit should record according to its status! Since the printer unit records image information in response to the command, the image processing information forming unit directly records the image while recognizing the status of the printer unit. Therefore, image recording can be performed effectively.

(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 the routine work of image editing can be easily performed on the leader section side as well.

(13) Image information can 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,
When transmitting to other systems on the optical fiber network, the number of copies can be specified for each destination, so image information can be transmitted easily and quickly.

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

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

<18) A command to start the league section is provided in the command menu section of the m-collection station, and by inputting that command, the league section can be made to read the manuscript image. When it is necessary to cause the league 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, the command menu section has commands for specifying areas to be shaded and dithered in the image, greatly increasing image processing ability and making the work easier. can be done.

(18) 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. Since a command for temporarily storing the image in the buffer memory is provided, image editing can be performed easily, reliably, and quickly.

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

(22) When editing images and creating editing programs, etc., the CRT display screen displays what the operator will do next. Users can easily and quickly understand the operating procedures even when editing images.
