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 machines as a means for copying original images, facsimile machines 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.

Purpose The purpose of the present invention is to eliminate the above-mentioned problems and to easily and quickly perform image processing of image collections, short-range communication, and long-distance communication of image information at low cost. An object of the present invention is to provide an image processing device.

The address/data buffer block to-g has two address/data buffers, each with a signal line 10-
//! and 1rO-//l to multipath 3θ and internal bus 10-j, and receives and passes address information and data information to and from these buses.

The internal bus to-r of the DMA controller 10 comprises a 16-bit address bus with an address space of ≦Dakilobytes and a t-bit data bus.

10-≦ 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! I via rO-/co0

The synchronization signal generation circuit 10-7 receives the above-mentioned IORC signal and INTAffi signal, and the address decoder 10-10.
A signal for confirming the response of the ROM10-1 is generated by the chip selection signal supplied from the ROM10-1 via the signal line 10-/KOJ, and this signal is sent to the clock generator 10-1 via the signal AGO-NOKO6. By supplying I10

A signal for selecting or is outputted to Royto-z and the synchronizing signal generating circuit to-y via signal line 110-/co3. A signal @10-113 from the bus controller 10-J to the address decoder to-io transmits a B signal which is a type of status information. That is, the Sco signal is a signal for identifying whether the address information latched in the address/data buffer block 10-* is address information for the internal bus tO-S or address information for the multipath 30. , address decoder 10-10 performs the identification.

Here, the operation of the DMA controller 10 in receiving and passing address information and data information to and from the multi-node 3θ and the internal bus tO-S will be described.

First, we will discuss the multipath 3θ and the case where the information is received and passed. When the I10 processor 10-/ outputs address information to the address/data buffer to-II, the bus controller 1rO-J supplies AL details to the address/data buffer to-U.
The address/data buffer (to-y) latches address information into the address buffer. Also, when the bus arbiter tO-S acquires the right to use the multipath 30 after latching, the bus arbiter tO-S latches the address information into the address/data buffer 10- The AEN signal is supplied to the DM l, and the address/data 7 to -411+ outputs the latched address information to the multipath 30.
If the A controller 10 is in write mode and the multipath 30 has been acquired, then! The processor 10-/ outputs data information to the address/data buffer tO-U, and the address/data buffer to-ni
, upon receiving all the DEN signals from the bus controller 10-j, outputs data information to the multipath 3θ. On the other hand, when the DMA controller IO is in read mode,
Address/data buffer tO-a reads data information on multipath 3θ and supplies the data information to I10 processor 10-/. Reading of data information by the I10 processor 10-/ is performed by confirming the 1xACK signal transmitted from the disk memory 90, which is the data transfer destination, to the I10 processor 10-/.

Next, the operation of the address/data buffer to-p connected to the internal bus to-r is almost the same as described above, but in this case, when outputting address information to the internal bus lrH, the bus arbiter 10-2 does not require an AEN signal. Also, whether or not to output data information to the internal bus tO-S is determined by the bus controller to-3.
Determined by the number.

As the disk memory 90, for example, WDS-10 of Sword Computer is used. The disk memorator O has an internal disk controller circuit (not shown), and this circuit is connected to the internal bus tO-S of the DMA controller to via the data bus to-iqo, and also has a signal line to
-iu and to-i4!3, the synchronization signal generation circuit to-7 and I10 processor 10-
/ is connected.

The data bus to-t4to transmits command information, result information, data information, and status information, and the former three pieces of information are collectively assigned an l 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. Additionally, an l address is independently assigned to the status information. Here, the command information is information that specifies the address and number of bytes on the disk memory 90, and the result information is information that specifies the address and number of bytes on the disk memory 90.
The signal line 10-1 transmits a command busy (CBUSY) signal, and the synchronization signal generating circuit rO-7 transmits the above three information and status. Identify information. In addition, command information,
a set of information consisting of result information and data information;
Status information differs in the timing at which the data becomes ready, and also differs in read mode and write mode, so the synchronization signal generation circuit t

The bank space of the buffer memory is toooo ■ E from the sowing area
Although it has a capacity of r94 kilobytes up to FFFFIlit, as mentioned above, the storage capacity of the buffer memory circuit block is 1qtrrlIo bytes, and it is not possible to store all of it in the bank space of the buffer memory. Therefore, the buffer memory space is divided into three banks, namely, Punk O and Punk L Oyohi Hankuko, and the CPU
Circuit block/signal line from θ/,,? . This division will be explained below.

The communication program space uses t kilobytes of the RAM (n kilobytes) 10-3 in the CPU circuit block lθ. In addition, the work RAM space is

FIG. 9 shows an address map of buffer memory n in the buffer memory circuit block. This buffer memory n has an Al size (spy mm x 2t).

M) has the ability to store information obtained by dividing the original into 166 pixels per l. The leader section SOO is that A4! Main scan the original size in the vertical direction (297mm direction), then CCU! 170. ! IrO and! ri0 is 1III1
It is divided into 1/≦pixel and supplies 4I712-bit pixels per 1 scan to the image processing control unit ioo. Further, the reader section 200 sub-scans the document in the width direction (the direction of 10I!I11), and scans the document in the CCDZ70, 110 and ! Since the scanner 90 also scans in this direction by 1fi111 lines, the document is scanned by 3.3tO lines in the width direction. Therefore, AII size manuscripts are no! It is decomposed into 966,720-bit pixels, and the image processing control unit 100 has 117
A: 2-bit pixels are supplied in series 33≦O times.

The procedure for assigning addresses to the image information supplied in this way and storing them in the buffer memory n will be explained.

First, the AII size manuscript / mm x / l11
It is divided into 1m square unit blocks and is composed of t2370 blocks. In one unit block, there is a /l line (coj6 bits) with l≦bits, and if 74 bits in the vertical direction are taken as an l word and one address is given to that l word, there will be 7 bits. The unit block is composed of a group of pixels having lB addresses. The first line, i.e. 7 of the first scanned document.
The serial image information of 4I7j kobits for the line is divided into pixel groups of 6 bits each corresponding to 7 pixels in the vertical direction of the original, and is supplied to the image processing control unit 100. The pixel group of is oo of buffer memory n.
ooO′#earth, next! ≦bit pixel group is oooioH
It was stored like 0010m.

The addressing of each line to the buffer memory n is as follows:
This is done by the CPU circuit block IQ setting an initial value to address counter 2/-4.

Also, the image information is transferred from the buffer memory n to the printer unit ≦0.
When outputting to 0, as in the case of storing image information, it is read out every 16 addresses from the initially set address.

Next, for the image information of the f7r cobit for the second line, from 0000/Hti to 0 in the same way as the first line.
Stored up to /21/n. In this way, /! from the 1st line to the 1136th line! 136 lines (96 circles in the width direction) are stored from address oooooH to address glFFH, and this address space is designated as bank O on buffer memory n.

Next, make the lj3≦ lines from the 1st!37th line to the 3072nd line the same as in bank O to create 70000 ribs)
This address space is stored as bank l on buffer memory n. Furthermore, the 307th
21 rl lines from the 3rd line to the 3360th line are stored from the Eoooo'H location to the FIE/F location, and this address space is used as a bank code on the buffer memory n.

As described above, if the method of storing l words of image information with l addresses is used, all of an A41 size document is stored at consecutive addresses on buffer memory n, with a square of lll1m×/rm as a unit block. This means that the area can be stored. As a result, when the operator specifies the image processing area in units of lungs using the console unit Ko00, when registering the specified area in the disk memory 90, DMA transfer can be performed by simply setting the starting address and the ending address of the specified area. The image information can be transferred at high speed without going through the CPU circuit block 10.

That is, by specifying a set of the first address and the last address, image information of main scan/j lines (/mm width) is
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 with a length of 2 Drran in the vertical direction, address setting using the CPU circuit block /θ only needs to be performed once.

Further, since the address corresponds to the position on the original image in square units, when editing the image, the operator can simply specify the position on the original in square units, which is convenient. In this example, since CCDs 170, 110, and 190 having a reading capacity of 76 bits per '/' mm were used, it was decided that l addresses correspond to /≦bits in the vertical direction. The number of bits is that CCD17
Other numerical values may be used depending on the capabilities of 0, 110, and 190, and the same effect can of course be obtained even if the address is set in units other than fin units, such as inches.

The multipath 3θ has a 74-bit data bus and a 〃bit address bus, but the area that can be accessed by this multipath 30 is 1 megabyte. In other words, it is possible to access 106 pieces of t-bit data, but when accessing 74-bit data, it spans the first location, so in this case, as shown in Figure 9-2, /6-bit data is accessed. Consecutive addresses are assigned to data every seventh address, and 16-bit data is input/output only when an even address is accessed.

Since the actual address in the buffer memory circuit block is the address shown in Figure 9-7, the multipath 30
When accessing the buffer memory n from the buffer memory n, as described above, the address converter 27 in the buffer memory circuit block converts the address shown in FIG. 9-2 into the address shown in FIG.
Convert to the address in the diagram. This address converter allows the address area of the buffer memory n to be set in any address space.

(3, S) Disk Memory FIG. 10-1 (5) shows the physical address structure of the disk memory 90. Reference numeral 91 denotes a drive, which is numbered O2, 8, . . . corresponding to the number of disk devices.

In this embodiment, seven disk devices, that is, only the number 0 drive is used. The drive 9 has three heads 92, each head 9.2 has 31 tracks 93, each track 93 consists of 11 sectors, and each sector 9 stores 372 bytes of data. can.

Therefore, the storage capacity of disk memory 90 is approximately lθ megabytes.

In the disk memory 90 having such a configuration, the t-th
The address on the disk memory 9θ is changed according to a certain sequence as shown in o-tFA(B),
Access data sequentially.

As shown in this figure, the sheet ten large number 8NA, the head number t, and the track number TN have a relationship determined by the following equation (1).

SN-,? Xchutai HN (however, HN-M, TN-G

If) (1) In other words, when a certain sequence number SN is determined, the track number TN and head number group are determined accordingly, and the addresses of the next accessed head 9 and track 93 are based on the previously determined sequence number. These are the head number and track number obtained corresponding to the sequence number SN+/ which is SN plus l. And the sector within track 93? 4I access is
The sector number 5CTNO is performed in ascending order.

FIG. 10-2 shows an index table provided in a predetermined area within the disk memory 90, and the use status of the disk memory 90 is managed by this index table. In this embodiment, among the sectors 91 with head number HN-0 and rack number TN-0, sectors with sector numbers BCTN-O to BCTN-13 are used as index table areas, and among these areas, in particular, The sectors with sector numbers 8CTN-0 to 1 are assigned to the sector bit map table l indicating the usage status of each sector on the disk memory 9o, and the sectors with sector numbers 8CTN-9 to 1
3 sectors are allocated to the file index table for file management. Sector number 2 5CIN-θ ~ /3 is fixed area 6 of RAM 10-3 by a program (open program) that reads the index table into RAM 10-, E in CPU circuit block 10.
The data is written from address 000H to address 7BFFH, subjected to a predetermined operation, and then written to disk memory 90 again by a program (close program) that stores the fixed area of RAM 10-3 in disk memory 90.

The sector bitmap table is as shown in Figure 1O-3. 5 lA in descending order of sequence number SN
Divide into 1064 blocks of p bytes from N-0 to 8N-10≦, and one block contains 7 tracks.
In other words, data indicating the usage status of lr sectors is
Allocate and store l bits per sector. As data indicating the usage status of a sector, for example, if a certain sector is in use, the sector pick F corresponding to that sector is
If it is unused, "O" is stored.

When registering a new data file in the disk memory 90, find an area where the number of consecutive sectors required for registration are empty, and enter the sequence number 8N and sector location (?IN) corresponding to that area. 1/'' is stored in the sector bit corresponding to that sector. Conversely, when erasing a data file, 10'' is stored in the sector bit indicating the corresponding area. The bit, that is, block O, has ′
ll' is stored and writing to this block O 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 1 registered in the system, namely, image data files (image files), application files, and control programs for this system. Assuming that the image file is of file type O and the application file is of file type CO, the management status of these files using the file index table is shown in Part 10-
As shown in the figure below.

File index pull FIT/ is status A, MAX block, l block size and current)
It consists of one block of -bytes each, numbered B, and is provided at the time of initialization of the disk memory processor O 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 disk memory 0, and in this example, the total number is set to go(npt).
Set to . l 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 31 as described below.
(g) I) byte. The current B number stores the number of files registered in the disk memory 90, and when registering a new file, the current B number is compared with the number stored in the MAX size. If the MA does not exceed
If the number exceeds the number of size X, it is not added and new registrations are not accepted.

Conversely, when deleting one file that has already been registered, the number stored in the current number B is decremented by l, and the file is deleted from the disk memory 90.

FITJ and FITJ indicate file index pulls for file type O and file type 2, respectively, and each stores 31 bytes of data. In FITJ and FITJ, R8
V is a cobyte area used for system expansion, and is unused in this embodiment.

When an operator arbitrarily assigns a number from 1 to 9 to a file and registers it in the disk memory 90,
This is a 2-note area that identifies the file number.

The file type is a 2-byte area in which data of the above-mentioned file type 10n or +X" is written.F
The bank and address in the ITJ are 2-byte and 1-byte areas, respectively, used when puncturing and addressing the RAM 104 on the CPU circuit block lo and allocating an application file to FLAM lo-3. The byte count is an area where the data length of the registered file is stored.

The seven-byte count is a one-byte area that stores the number of sectors used for the registered file. Sequence/1
6. Drive, 4. The head rot, track shoulder, and sector rot are areas of each byte that store the starting cetance number, drive number, head number, track number, and sector number of one storage area for a registered file.

XO, YO, X/, and Y/ in FITJ are each a cobyte area, and in the case of file type "eIO", the coordinates indicate where on the copy paper the image information of the area to be edited is placed. Store data.XO, Y
As shown in Figure 10-5, O, By indicating the farthest point B using the stylus pen 210,
The coordinates XO and YO of the point and the vertical length X/ and horizontal length Y/ of the editing area are determined, and these values are stored in hexadecimal.

For file type co, as shown in FIT3, F
The areas corresponding to XO, YO, X/ and Y/ of IT2 are unused areas.

When transferring a certain image data file from the disk memory 90 to the buffer memory, first, when the file number is specified, the index table is transferred to the RAM 10-3 by the open program, and the index block of the specified file number is obtained. Next, the XO of that block.

The address on the buffer memory n is calculated from the data stored in YO, X/, and Y/, and the image information in the disk memory 0 is DMA-transferred into the corresponding area of the buffer memory n.

Also, when changing the position of the editing area on the copy paper,
Since X/ and Y/ are unchanged, only XO and YO can be used as parameters, and only those XO and YO can be changed by an image position change command (described later) from the console section -○○.

In addition, the disk memory 90 stores the control program of this system, and the file is set to file type l.
Its file index block is configured similarly to FITj.

This system converts image information into W and 2 numbers,
The method of transmitting it to other systems is CCITT's T,
According to the Recommendation T,4 (the following points should be considered when applying the Recommendation to the present invention.

(1) In the device of the present invention, the vertical direction (direction in the order of 2 to 7) of an A4I size document is 7 lines, and the resolution is /≦bit/mm, so the maximum run length, that is, the l line is all The run length in the case of white or all black is 4I7g, which exceeds the maximum representation range of 26λ3 (-1!60+63) of the extended dish code.

(b) The device of the present invention performs transmission using a two-dimensional encoding method with parameter K set to infinity.

That is, for an Ap size original, the first line that is first transferred to the 'DDX interface≦0 is double-encoded, and then the remaining 3359 lines are double-encoded.

Regarding point (1), the reason why the length direction is set as the l line is as follows. In other words, (1) reducing the number of transmission lines to reduce transmission time, and (
It) By reducing the overall movement distance of the sensor in the sub-scanning direction in the reader section joo, the reader section! Try to downsize OO.

Regarding point 0), the reason why the parameter K is set to infinity is to set the parameter K to a small finite value and save the time of repeating plate encoding every time.
The reason why can be set to infinity is that the image information to be transmitted has already been binarized by the COD driver and stored in the buffer memory n, and the parameter K is set to a small finite value to reduce the reading error. This is because the meaning of making it smaller is lost.

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

The image information of 1542 minutes (ti7s bits) transferred from the mass and buffer memory n via the signal line /37 is transferred to the line via the data/4 interface 40-/ and the write switch ≦0-J. Buffer≦0-4
! , ≦0-j or tO-4.

This image information is transferred to a line buffer 10 in synchronization with a 10 MHz (MH2) clock signal at a transfer rate of 7 bits with one kl of 0.7 microseconds (-a).
-! Or ≦O-Transferred to Party B. That is, the transfer time of the image information of the l line is 4I7. t, 2μB.

The image information of the 7th line that is transferred first is transferred to switch 4.
0-3, the line buffer ≦0-42 is first supplied, and when the line buffer to-q finishes storing the image information of the first line, the switch 4Q-7 opens the gate of the line buffer 40-p. , close the gates of line buffers to-S and to-4, supply the stored image information to the RL counter to-r, and
The image information of the first line whose white and black run lengths are counted and run length encoded is RL@
The B@/MR converter to-io converts it into a ■ code. While the line buffer 40-4< is outputting image information, the switch 60-j closes the gates to the line buffers to-y and 10-1, and the line buffer ≦0-j
The second line of image information is supplied to the line buffer tO-S. If all the image information on the first line is partially encoded, the image information on the second line is supplied to the RL forward/reverse counter 60-7 by the switch 40-7, and the relative pixel information from the first line is The changing position is counted and RL(c)■1 侃Converter to-/.

It is encoded by The image information of the third line transferred to the line buffer 40-6 is also processed in the same way as the second line.

Next, the run-length encoded image information supplied to the RLHMH/MR converter≦0-10 is plate encoded or

As mentioned above, in the device of the present invention, the maximum run length is 4Z7J'J, and the maximum expression range of the extended dish code is 1? In order to exceed ≦23, the following method is used to further expand the code.

(1) Run length RL (2A: In the case of tO, it is expressed by the usual MH code. In other words, if ...< ta, it is 1

Figure 12-2 shows each signal, its name, and image processing unit lθ, !
= A diagram showing the direction (arrow) of signals with the DDX interface 60. Here, FG and SG are a safety ground line and a signal ground line, respectively. The call request signal (CRQP) is a signal in which the image processing unit 10 requests the DDX interface 10 to connect (call) with another system, and this signal is activated by the connecting signal (CND). At the same time, the power is reduced, and the connection failure signal (NR
YD) is energized, it is treated as invalid.

The call signal (CIP) is a signal sent by the DDX interface to the image processing unit 10 indicating that a call has arrived from another system.

The connection request signal (CNQ) is a signal from which the image processing unit 10 requests the DDX interface 10 to connect to a DDX line, and is activated at the same time as either CRQP or CIP is activated, and NRYr)bf 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 lθ cannot become capable of transmitting or receiving within 6 seconds. When the NRYDI or DDX line 100 is in a busy state, or when the NCUrOλ not ready switch is activated, it indicates that the line cannot be connected. This NRYr@ line is always energized or deenergized depending on whether line connection is disabled or enabled, respectively.

Further, if CND is not activated even after a certain period of time has passed after CRQP is activated, the image processing unit 10 determines that connection is impossible.

CND is activated when the communication conditions between this system and the other communication partner system (partner station) are established due to the activation of CNQ or CIP and the activation of CNQ, and the line connection is completed. , indicates that this system is ready for communication.

CND is de-energized when CNQ is de-energized or when the other station disconnects the line. The ready-to-send signal (RDR) and ready-to-receive signal (RDR) are sent to the image processing unit/
Indicates that θ can be in a state where it is possible to send and receive image information for 7 A4 (size) documents within 6 seconds,
Simultaneously with CNQ activation, RDS or RDR is activated.

Transmit mode signal (MDS) and receive mode signal (MR
R) indicates that the system is set to a mode of transmitting and receiving image information, respectively; these modes are determined by looking at the RDS and RDR of both the calling and called parties. 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 after the MDS or MDR is activated, indicating that image information can be transferred in transmit or receive mode.

The transmission data request signal (RQS) is energized and deenergized at regular intervals, and the DDX interface 60 requests the image processing section /θ to transfer 1 ray 2 worth of image information.

When RQS is activated, the image processing unit lθ activates the transmission data valid signal (SVA), and transfers data from the buffer memory to the DD.
X interface Oto 0/2 minutes of image information (SDT
) transfer. 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 (PIcK), and deactivated upon completion of SDT transfer. R
The VA is energized at regular intervals, and the DDX interface 60 receives from another system, requests to receive the decompressed image information (RDT) for two minutes, and samples the RDT in synchronization with the reception clock (RCK). Indicates permission to do so. The repetition period of RVA is similar to RQS. 8DT and RDT are the transmission and reception of the λ value in white and black, respectively, 8CK and RCK.
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 100, the transmission direction is the calling system (calling station) and the called system (calling station). Both stations (called station) compare RDS and RDR and decide as shown in FIGS. 1 and 3, thereby preventing errors in the transmission direction. That is, in FIG. 72-3, as shown by the energized state by ○, the transmission direction by an arrow, and the deenergized state and transmission disabled state by X, only the RDR on the calling side and at least the RD on the called side
When S is activated, and when only the RDR and RDS on the calling side and the RDS on the called side are activated, the transmission direction is from the called side to the calling side. Also, only the RDS on the calling side and at least the RD on the called side
When R is activated, and when the RDR and RDR on the calling side and at least the RDR on the called side are activated, the direction of transmission is from the calling side to the called side. Transmission is disabled with combinations of RDR and RDR@l of both the calling and called stations other than those described above.

No. n-tlm shows an example of a procedure for performing transmission between the calling station and the called station.

Here, IDS is the transmission capability identification signal, which refers to the transmission capabilities of the calling and called stations, i.e., RD
This is a signal that informs S and RDR of each other. For example, the transmission format is \″0000 RDS
RDR/0'' will be transmitted sequentially from the most significant bit to the least significant bit, and both stations will transmit the system's RDR and the partner station's RDS and RD.
R, 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, "o o o i'o".

10” is sent in the same way as in the case of IDS, and the ID
This indicates that transmission and reception of image information for one document in the transmission direction determined by the communication of S has been completed.

MH/ is the image information of the first line encoded, MR2
~MRn+/ (/≦n≦33≦0) is MR encoded image information of the first to n+/th lines, MT(n is dish encoded image information of the nth line, and M(n -1-
/~MR,33tO is the kite encoded n+/~33rd
60 lines of image information, MH/-MRJ3tO
shows image information for seven sheets of Al-sized originals.

RTQ is a retransmission request signal, and if there is an error in the received image information of the line, that is, when the called station demodulates the transferred image information, the length of the line is O or 4t7JJ bits. If this information is not obtained, this information is not taken into the buffer memory n 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
A signal obtained by adding l to the line end code EOL in the T and II recommendations by the CI TT is transmitted to indicate completion of transmission of one image's worth of image information.

DCN is a line disconnection signal, and its transmission format is, for example, "0/0000/0" with ID
S is sent in the same manner as S to notify each other of line disconnection.

Immediately after the line is connected, the calling and called stations begin sending IDSs to each other, and repeat this process at least three times until their stations are ready for the transmission mode. Here, for example, at time A, if the transmission direction cannot be determined, both stations determine that transmission is impossible (see Figures 1-3) and disconnect the line by mutually sending DCNs. 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.

A4! In transmitting image information for 7 size originals,
For example, at time E, if a transmission error occurs in the image information of the nth line, the called station sends an RTQ to the calling station, and the calling station responds accordingly. , the image information of the nth line is encoded, and the image information from the n+/th line to the 3360th line are sequentially MR encoded and transmitted.

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 Figures 1 and 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.

(3°l) Optical Fiber Interface FIG. 13 is a block diagram showing an example of the configuration of the optical fiber interface circuit yO. Optical signals (VIDEO) carrying commands or image information transmitted from fiber optic network 700 through fiber optic cables 701 and 702

The command/image identification circuit 70-3 is a circuit for identifying whether the transmitted signal is a command for specifying the size of the document, text, or image information. When the transmitted VIDEO signal is command information, a command identification hood is added to the beginning of the information, and the command/image identification circuit 70-3 extracts that code and identifies it as command information. In addition, in the case of image information, the CLK signal has a predetermined frequency (e.g. /j.jMHz
), and the command/image identification circuit 70-3 identifies it based on its frequency.

As a result, if the transmitted VIDEO signal is identified as command information, the command/image identification circuit 70-3 generates a command recognition (CACK) signal, and during the period of receiving the command, the command/image identification circuit 70-3 generates a command recognition (CACK) signal. , send this signal to signal line 7

On the other hand, when the command/image identification circuit 70-3 determines that the "r<vx(3)" signal transmitted from the optical fiber network 700 is image information, the command/image identification circuit 70-3 performs image recognition. (IACK) signal is generated and this signal is sent to the signal line 7O during the period when image information is being received.

(a, 3) Editing procedure The procedure for editing image information using the editing station OO will be described with reference to FIGS.

When the editing stage Sunsan〇〇 starts up, first step S
The display division of the CRTJOO screen and the initialization of system constants are performed at /. CFtTJOO has a screen 30/ that can display Q characters horizontally and 24I lines vertically.

FIG. 22-7 shows an example of display division of the screen JO/, where 3IO from the 7th line to the 19th line is a working area, and the image processing unit 10 is connected to the editing station ti.
The characters transferred to oo are displayed. 3-0 on the third 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 first line is a mode display area, where the operator can
Displays which mode (described later) is used.

3410 on the nth line is a message area where the editing station control unit 4Iso displays to the operator the next command and parameters to be input, error hood, etc. 3jO on the nth line is a user input canister,
Monitor characters such as file numbers input by the operator. 360 on the 21st line is a status display area, which is an area where the status of the image processing section 10 is displayed and notified to the operator.

As other initialization, when a command is input, the echo-packed command from the image processing section /θ is displayed in the working area 31O, the carriage return code is recognized, and the next command sent back from the image processing section /θ is displayed. command is displayed from the left end of the next line, and if the command is displayed from the 7th line to the 9th line, the working area 31O is scrolled up line by line, and the command power is always displayed in the working area 31O. Make it possible to fit it. When the editing station lOO is not on-line with the image processing control unit 10O, screen 3 in FIG. 22-7 is displayed.
For example, if 0/ is all blue, message area 3
11O to the operator's online request, i.e., “REQ
Waits for input to accept the "UEST" key.

Editing station 1Ioo can be roughly divided into two modes:
That is, it operates in echo mode and edit mode. In the echo mode, characters input by the operator via the console section 200 are transferred as they are to the image processing section IO, and also from the image processing section 10 to the editing station UO.
In this mode, characters transferred to CRTJOO are displayed as they are on CRTJOO. The edit mode is a mode in which application files are created, modified, and execution commands are given to the image processing unit/θ. In this mode, characters input by the operator are first temporarily stored in the RAM μSt in the edit station control unit 1Iso. , the operator is C
After arbitrary correction on RTJO (1), image processing section /θ
will be forwarded to. Also, in edit mode, disk memory? The period during which the application file transferred from O to the editing station control unit 4ISO via the image processing unit /θ is particularly set as the command mode.

FIG. U shows the operation of the editing station control section IIgo when there is key human power in each mode. First, the mode is determined in step SA, and as a result, the
If it is determined that the mode is selected, the process proceeds to step SR, where the character echoed back from the image processing section 10 is displayed on the working area 31O, and the process proceeds to step SG, where the routine returns to the normal routine shown in the first figure. 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.
10, 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 reception completion flag of the application file, and
The process moves to step SG. On the other hand, if the determination is negative, the process proceeds to step SE, and the transferred characters are stored in the RAM.
The data are sequentially accumulated in Lt4, and the process moves to step SG.

By instructing the "REQUEST" key, the process advances to step S3, where the editing station 1loo is set to the echo mode, and in step Sl, it outputs a start request signal for the image editing program to the image processing section /θ. Next, in step Sj, the startup of the image editing program is confirmed, and if the determination is negative, the process moves to step S, and if the determination is affirmative, the process moves to step 84. In step S≦, CRT
For example, the screen of JO0 may be entirely black, and the message area 3170 may display "0N-LINE" in green text to notify the operator that the request to start the editing program has been validated, and the mode display area may be In 330, “
ECHOMODE” and edit station 11.
00 notifies that it operates in echo mode, and waits for a command input in step S7.

In step St, the command key input from the console unit 200 is determined, and according to the determination result, step S/θ, 813, 820, 82! ;Or move to S3.

In the echo mode, the screen editing function of the CRT 300 does not exist, so if there is an input from the key group 229 related to screen editing, it is processed as an invalid input in step S/θ, and the input is processed as an invalid input in step S7.
and wait for the next input.

There is also a key for exiting edit mode, i.e.
The same process is performed when the edit reset key and edit end key are input.

In the key n-2-2-2 (if the 1'r command character is input, step S15 is entered)
Proceeding to /4, the input command is transferred to the image processing unit /θ, and the system operates according to the command.

For example, as shown in Figure 2)-2, when the RE" key is input, the characters "RE" are displayed on the screen 30/, and by instructing the gear ridge return key 22k, the reader drive signal is sent to the reader section joo. The original image is read.

Coordinate input request key j, 27, i.e. “position specification”
key and 6 area designation key, step S
Then, it becomes possible to specify a desired point on the original document placement section 2IIO with the stylus pen-10. When editing an image by specifying the area to be edited, if you specify the 6 area specification key, a message such as EN
TERTOP RIGHTPO8ITION", the left half of the working area 310 is displayed in white to prompt the operator to point A (see Figure 70-3), and the left half of the working area 310 is displayed in white to display image information. The editing area 31k is displayed.

2) When the operator indicates point A, a coordinate display line is drawn in green, for example, in the vertical and horizontal directions of point A/, which corresponds to point A, on the image editing area 3//, as shown in FIG. ? /, 2 are displayed, and the X and Y coordinates of point A, that is, XO and YO, are displayed in the user input canister 3jO in units of x. Next, in the message area 330, press “ENTER”.
"BOTTOM LEFT PO3lTlCN" is displayed to prompt the operator to input point B. When point B is input,
In step 82/, the vertical and horizontal lengths X/ and Y/ of the edited image are calculated from the coordinates of point B and the coordinate of point A, and then in step s22, the lengths X/ and Y/ are calculated by inputting the points A and B. The editing area is displayed in red, for example, in the corresponding area 313 above the image editing area 31, as shown in the second) image editing area. At the same time, message area! , 30 Displays "OK! AREA Is RECOGNIZED" to inform the operator that the editing area specification is complete, and displays XO, YO, X/, and Y/ in mm units in the user input area and iro. . Then step S
/4 and transfer these numerical values to the image processing unit /θ.

In addition, when editing an image by specifying a position, specify the 1 position specification key. In this case, specify only 7 points, that is, specify only point A when specifying an area. When input, for example, the coordinate display line 3/l is displayed in red, and the user input canister 310 displays XO and YO in units of coordinates.In this way, the editing station 1Ioo
When recognizes the specified position, @0KIPO8ITIONIs RECOGNIZED is sent to message area 3.30.
” is displayed to inform the operator that the coordinates have been validly input, and the numerical information of XQ and YO is transferred to the image processing unit 10.

When the area specification or position specification is completed, the process returns to step S7, and the editing station 110o again waits for input from the console unit -○○, and by inputting a new command, the command displayed before the execution of area specification or position specification is changed. The specified coordinates are displayed on the working area 310 as shown in the second diagram. Additionally, if the operator issues another command key after pressing the 'area designation' key or 1 position designation key and before inputting coordinates, the (///) area designation or The state of waiting for input of coordinates for specifying a position is canceled, and the command that was displayed before the instruction of the ``area specification'' key or the 1 position specification key is displayed in the working area 310.

To release the editing station t100 from the control of the image processing unit 10 and cancel the online state, input the KL command using the alphabetical key group λ3.

At this time, proceed to Step S Colo via Step S O,
The character information of "KL" is output to the image processing unit 10 to request termination of the image editing program, and the process proceeds to step S27.In step 8.27, the editing station control unit lI5θ sets the image processing unit /θ If it is detected that the editing program has not ended, a negative determination is made, the end input is invalidated, and the process moves to step S7.
Step Su? If an affirmative determination is made in step S/, the online state is canceled and the process moves to step S/.

Input a group of keys 22t related to application files,
In other words, if there is an instruction using the ``Standard Work'' key, the ``Call Application File'' key, and the ``Create Application File'' key, edit at step f3JO as shown in Figure 1. Station clock oO is set to edit mode.

Here, the ``Create Application File'' key is a key that instructs when creating a new application file, and the ``Call Application File'' key is a key that instructs when creating a new application file. This key is used to call up and modify an application file registered in , and the 'Standard job' key calls up an application file and sequentially transfers its command sequence to the image processing unit lθ for image editing. This is the key to give instructions when performing.

When those keys are input, step S, ? / performs input determination for each case of routine work, application file calling, and application file creation. In edit mode, since application files are handled, it is essential to specify the file number. Therefore, in any case, first step 831
, the editing station control unit lIgo is a CRT 3o
For example, if the screen of o is blue and the message area is 3g θ
@ENTERFILE No, AND CARRI
AGE RETURN'' is displayed and the operator is requested to input the file number.Then, ``EDIT MODE'' is displayed.
” is displayed in the mode display area 330 to inform the operator that the editing station θO is in the edit mode, the screen of the CRT 3θO is returned to black, and the following processing is executed according to the respective processing procedure in each case. do.

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

In step 83.2, when the application file number is input, in step S, the editing station control unit lt3θ enters the message area 3DAO.
NTERMENU! ” is displayed to prompt the operator to create an application file.Then, the cursor 3θ
The operator waits for command input by blinking the icon in the upper left corner of the working area 310, and then inputs a desired group of commands one after another to create an edited program. By inputting one command and adding a carriage return, the command is transferred to the RAM Il,tA in the editing station control section lv and displayed in the working area 310 at the same time. in this way,
Since the input command group is stored on the RAM ljA, by instructing the screen editing key group 229, the screen editing function, that is,
Erase the line or character where the cursor 3θ is blinking,
You can insert new lines or characters, move the cursor, etc. If the number of lines that can be accommodated in the working area 310 is exceeded due to the creation of new lines in the editing program, the working area 310 will be scrolled up one line at a time in the same way as in echo mode, and in addition to The downward movement also causes the working area 310 to move up and down.

When creating an application file, processing for input specifying one area is executed in the same way as in the echo mode, but processing for input specifying a position is executed as follows. The position specification input when creating an application file is LO (
This is related to the input of the coordinates Xθ and YO of the ADH(...) command that is input next to the ...) command, so make sure that the LO(...) command has been input in advance, and Search for CR (...) from the command group that has already been input, and find the coordinate information XO of the same file number.

Extract YO, Xノ and Y/. As a result, if the coordinate information cannot be extracted, the process shown in the figure is performed in the same way as in the echo mode. On the other hand, if such coordinate information can be extracted, the right half of the working area 31O is made white, for example, and XO, YO, Area 3/4 defined by X/ and Y/! For example, A is displayed in green. Then, the area 3/'IB defined by the working error coordinates XO' and YO' is displayed in red. Also, both areas? /l The file number FN of the image file is displayed in the upper left corner of A and 311IB.

Note that if the new editing area formed by XO', Yθ', X/ and Y/ exceeds the editable area,
' and YO' inputs are invalidated and a new valid input is awaited. The focused image area displayed by inputting coordinate information is erased by inputting a command, and the command group being created is displayed again.

1 Trace" key is input, the LO (...) command from the command group of the program being created and the CR (...) with the same file number as the LO (...) command are input.
・) Search for the command and, as shown in Figure 2J-4, set the left side of the screen of the CRT3θO as white, for example, and create an area defined by the coordinate information XO, YO, X/ and Y/ within that plane, 7/ 1, A, and 7/7 A are displayed in red, and the file number FN of the image file is displayed in the upper left corner of the area. On the right side of the screen, this is colored blue, for example, and the changed coordinate position information XO is displayed within that plane.
Area 31 defined by ' and TO' and X/ and Y/
A B and 3/7BTt are displayed in green. Further, a rightward arrow 37 is displayed in the center of the screen to indicate movement of the image.

When all the image file movement indications are completed,
Message area 3 is "END OF TRA"
CEMODE" is displayed to notify the operator of the end of tracing. When the operator then points to an arbitrary point on the console section O, 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, m collection image area CXO, Y
O, X/, Y/), edited image change position (Xθ'
, YO2) and the number of prints by numerical values, it is also possible to create a program using these as variables to provide flexibility in image editing. For example, the following command group can be configured as an application file that performs trimming using variables.

(1) RE (CR) Leader section! Read the original using rOO and store it in buffer memory n (u) CR (N, D, F) (cR) File number N, area F (XO, YO,

S) (CR) Make 8 copies of the image information stored in the buffer memory 22.

That is, file number N2 edit Ii [7i image area completion is F
.

Create an application file with the image position as P and the number of copies as S.

In this manner, the operator creates an application program, and when the creation is completed, the operator inputs the editing end key in step S3Q.

At this time, the process proceeds to step S3s, and the editing station control unit 30 enters the message area 3.
IS COMMAND FILE 'i'” is displayed.
Check whether the application program stored in RAM IIj& is to be registered as a file in disk memory □. When the operator denies this message and inputs the @N'' key, a negative determination is made in step Sat, and editing station 4tso Gi x
The date mode is ended, the screen 3θl is erased, the process moves to step S37, and the echo mode is returned.

On the other hand, when the operator inputs the °Y'' key to request file registration, an affirmative determination is made in step 834, and the process proceeds to step 83g, where the file number is registered based on the file number set by the operator in advance in step 83g. , the editing station control unit +yθ sends the FD(...) command to the image processing unit 10 and obtains permission to transfer the application file.A file with the same file number as that file number is registered on the disk memory 9θ. If not, a negative determination is made in step S, ?9, and the process proceeds to step 5lIo, where the image processing unit 70 permits the editing station control unit θ to register the file, and the file transfer is executed.

When the file registration is completed, the process moves to step S3 and returns to the echo mode. If a signal is transferred from the image processing unit 10 to the editing station control unit 50 indicating that a file with the same file number as the created file has already been registered, step 839
An affirmative determination is made in step 81/, and the message area 31I0 is filled with, for example, @FILE ALRE.
ADY REGISTERED, DELETEOL
D'i''' is displayed, and the operator is asked whether or not to erase the file with the corresponding file number in the disk memory qo.

If the operator affirms, proceed to step S, 4ii
The image collection station control unit TISO sends the image data to the image processing unit 10, and then returns to step 83g. If the operator denies it, step I
Proceed to VJ, edit station control unit O is message 1! J 7 J'IOni''ENTERFILE NO

Prompt the operator to enter a new file number. When the operator inputs a new file number, the process moves to step 83g.

Note that if the specific volume of the image processing unit/θ with respect to the ED command is other than “error hood @θg”, the editing station control unit 3o determines that it is impossible to transfer the application file, erases the screen 30/, and sends an echo. At the same time as changing to the mode, the corresponding error code is displayed in the message area 3'IO.

Next, the processing procedure when an application file call key is specified will be described. Step S? - When the file number is entered at editing station 1lOO

Call the corresponding application file from RA
M4 (, Transfer to tA. Editing station control unit qs
When o completes receiving the application file, it resets to the edit mode in step 5II7, then moves to step S33, and deletes and inserts lines and characters using the same procedure as in creating the application file. Modify application files. In addition,! If an error code is sent from the 1iji image processing unit IO, the editing station control unit aSO
00 screen and return to echo mode, message area 3'IO and status display area 3
10 and 10 respectively display an error hood, an error message corresponding to the error hood, and a status.

Next, the procedure for routine business input processing will be described. Operation (1, 2
3) When the person instructs the ``1 Regular Work'' key and inputs the file number of the desired application file, the editing station control unit lIs;o transfers the specified file to the RAMIA, as in the case of calling an application file.
(Step S, ?, 2.8 digits 3-5II7
). Then, in step SIIg, the editing station control unit 1lso selects the RAMl1. ! The command group stored in tA is searched from the beginning, and the variables N, F, P and S are searched.
Search for. In step SII9, if those variables are not found as a result of the search, 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 SSO.

In step S3θ, the editing station control unit 1l
When ro first discovers the variable N, it displays a comment in the message area 30 of the CRT 30θ asking for the input of the file number, and then replaces the variable N with the numerical value input by the operator. Next, when variable F is found, a message area 3'IO is displayed asking you to specify an image area, and variable F is replaced with the values input by the operator (/col) XO, YO, X/ and Y/. do. Next, when the variable P is found, a message area 3170 is displayed asking you to specify the image position, and the variable P is set to the value X input by the operator.
O', YO', and if the position specification input is related to the combination of CR (...) and LO (...) commands, as shown in Figure 2.7-& If the process is related to only the LO(...) command, the n-th process shown in the figure is performed. Further, when the variable S is found, a message area 3410 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 SSl, where the editing station control unit GUSO performs tracing processing as shown in Figure 3-6 to change the editing form to the working area. 310, and then in step S32 the message area, yl
"OK'i'" is displayed on Io to confirm with the operator whether the image editing format is as desired. If the operator negates the confirmation by instructing the @N'' key, for example, the editing station control unit tUO erases the screen of the CRT 300 and proceeds to step 837.On the other hand,
If the operator, for example, instructs the "Y" key and affirms, the process moves to step SS3, where the editing station control unit no saves the screen as it is and transfers the command string to the M1 image processing unit 10. , execute a predetermined program.

The image processing unit 10 echoes the transmitted command character to the editing station control unit l13θ,
The editing station control unit lI3θ displays the command in the status display area 36θ to make the operator aware of the status of the system. When the image processing unit 10 finishes executing a series of commands, the editing station control unit lkO performs step S, ? Proceed to step 7, complete routine work, and return to echo mode. If an error occurs during the command execution process by the image processing unit/θ, the editing station control unit 1. At t and tθ, command transmission is interrupted, the CRT 300 screen* is erased, an error hood is displayed in the message area 31Io, and the mode shifts to echo mode.

In addition, in the processing in the above-mentioned edit mode, that is, in the processing of command file creation, command file calling, and routine work, if the operator instructs the edit reset key during the input processing of step S33 or step SSO, Immediately, the screen of the CRT 300 is erased, and the process moves to step S3 to return to the F-mode.

Further, if there is an end input, a KL command is output to the image processing section IO, the online state between the image processing section 10 and the editing station θO is canceled, and the process moves to step S-.

(7) Editing and transmission using the reader operation unit In this system, the 74th/illustrated reader operation unit 530 is used to read and copy original images.

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

(1) A reader unit that reads a document image, an image processing control unit that controls image processing, stores processed images, etc.
An editing station that edits image information, an optical fiber interface that mutually communicates image information between this system and other systems on the optical fiber network, and an optical fiber interface that performs mutual communication of image information between this system and other systems on the DDX line network. Since the image processing apparatus of the present invention is composed of a DDX interface for mutual communication of image information and a printer section for copying image information, it is possible to read image information, process image information such as image editing, and use an optical fiber network. It is possible to easily and quickly carry out short-distance communication of image information, long-distance communication of image information using a DDX line, and copying of image information at low cost.

(,2) m The image processing control unit is provided with a buffer memory to temporarily store image information, and a switching device is provided,
The flow of image information within the device of the present invention and image information transferred from other systems to this system via an optical fiber cable is switched, and one or more of the buffer memory, optical fiber interface, and printer section are selected. Since the image information can be transferred to each section, reading, short-range communication, and copying of image information can be processed in parallel, and image processing time can be shortened.

(, y) Image information that is transferred from other systems on the DDX line network via the DDX line network and DDX interface (/, ?/) is stored in the buffer memory. Regarding processing of image information,
When communicating image information between this system and other systems via the 0 (4Z) DDX line network, the same effect as product (2) can be obtained. , a signal RDS indicating that image information of a y7C draft of a predetermined size can be transmitted within a predetermined time, and a signal RT)R indicating that it can be received are mutually sent, and in both systems, the RDS and RDS of both systems are transmitted to each other. Since the transmission direction of image information is determined based on a certain combination with RDR, errors in the transmission direction can be prevented, and the time required to transmit image information using a DDX line can be shortened.

(, 5-) The DDX interface encodes image information for 7 lines in the vertical direction of the original image into run-length encoders, and then converts the image information for 2 lines of run-length encoded data into data using a two-dimensional encoding method. When performing compression, if the run length of the 7242 minute iii image information (/, ?, 2) information exceeds 26 3, the make-up code corresponding to the run length 60 is followed by
1 make-up code corresponding to the required run length length
After adding one terminating code, data compression is performed by adding one terminating code, so DDX
When communicating using a line, the total number of lines of the original image to be transferred can be reduced, and data compression can be performed efficiently, so that the transmission time can be shortened.

(4) When communicating image information between this system and another system via the DDX line network, the image processing control unit sends a signal CRQP requesting connection to the other system to the DDX interface, and a DDX A signal CNQ requesting to capture the line, a signal NRYP indicating that the image processing control unit cannot be in a state where it can send or receive image information within a predetermined time, and a signal NRYP indicating that the image processing control unit cannot send or receive image information within a predetermined time. It transfers signals RDS and RDR, which respectively indicate that the state may occur, a signal RQS which indicates that 7242 minutes of image information is being supplied to the DDX interface during the 11 period, and image information SDT. 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. a signal RQS that the DDX interface requests from another system, a signal RVA that requests reception of l-line image information that the DDX interface receives and demodulates from another system, and image information. These signal groups enable reliable communication of image information between this system and other systems.

(?) When communicating image information via a DDK 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, they mutually send a transmission preparation completion signal, the calling system starts transmitting image information for each line, and the called system starts transmitting. Transmission errors are monitored for each incoming line. When the called system discovers a transmission error, it requests the calling system to retransmit the image information 91 times starting from the line where the transmission error occurred. In response to the request, the calling system performs data compression using the co-dimensional encoding method, which starts with the line where the transmission error occurred and encodes the line one-dimensionally, and then encodes the following line two-dimensionally. Resume transmission. That is, image information can be transmitted reliably, and even if a transmission error occurs, the error can be quickly eliminated.

(ff) The optical fiber interface converts optical signals transmitted serially from other systems on the optical fiber network into electrical signals, and the signals are used to send commands and image information related to image recording from (/Jj-). G, m to reproduce and supply to the image processing control unit, and to convert commands and image information related to image recording to other systems into optical signals transferred from the image processing unit 818 and output to the optical fiber network. The L data (7) allows image information to be recorded without requiring any operation in the image recording system, thereby increasing the speed of image processing.

(ri) 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 status planning image processing unit of the printer unit. A recording preparation command is sent out according to the status, and the printer unit records image information in response to the command, so the image processing information forming unit can be used directly from the image processing information forming unit while recognizing the status of the printer unit. Image recording can be performed, and thus image recording can be performed effectively.

(/θ) The image processing control unit is equipped with a disk memory that can store image files, application files, and control programs for the image processing control unit, so it is possible to store, edit, etc. a large amount of image information. It can be done easily.

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

(/co) The reader unit is equipped with a reader operation unit, and the application file stored in the disk memory can be started from the reader operation unit, so standard tasks such as image editing can be easily performed on the reader unit side as well. .

(/3) Enable image information to be sent from the reader operation unit to multiple other systems on the optical fiber network and DDX line by specifying the destination, and in particular to other systems on the optical fiber network. in case of,
Since the number of copies can be specified for each destination, image information can be transmitted easily and quickly.

(/da) 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 image editing. can be done.

(7t) 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 unit 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 WI images and create application files for image editing, and even if there is an error in the input information, you can quickly deal with it. can be done efficiently.

(/6) In the command menu section of the m-collection station -
A command has been provided to start the reader section, and by inputting that command, it is possible to make the reader section perform the operation of reading the document image, so if it is necessary to make the reader section perform the reading operation during image editing work. etc., such operations can be executed only by operating the command menu section, thereby simplifying the image editing work.

(/7) Since the command menu section has a command that allows you to select a dither pattern, you can make such a selection just by operating the command menu section.
) can produce the same effect.

(7g) 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.

(/9) In the command menu section, there is a command to start up the printer section, and by inputting that command, (1, 39
) Since it has been made possible to have the printer section perform image recording operations, it is possible to obtain the same effect as the extra product (/l) when it is necessary to have the printer section execute recording operations during image editing work. It will be done.

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

Since the area on the digitizer and the address in the buffer memory are made to correspond to each other, image editing can be performed easily and without error.

(22) When editing an image or creating an editing program, the CRT display screen displays what the operator will do next, so that an operator with no experience in image editing can Even if there is a problem, you can understand the operating procedure and edit images easily and quickly.

(3) When editing images, etc., if the image editing area specified by the editing station exceeds the editable area of the device, a warning will be displayed on the CRT screen, so image editing can be performed reliably. be able to.

(all) When editing images, etc., an identification number is attached 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.

<X> Since the execution form of the editing program can be traced on the CRT screen, the execution form can be visually confirmed, and therefore not only the operator who created the editing program but also other operators can understand the image editing can be done easily and reliably.

(24) When creating the m-book program, we made it possible to input the number of records, editing area, etc. as variables, making the system more flexible.
Therefore, image editing work can be easily performed.
