Description

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

BACKGROUND OF THE INVENTION Conventionally, as image processing apparatuses, copying machines as 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 root function, such as changing the image density of only a part of the image. However, as copying devices become more equipped with such features, what about the devices? The problem arises that the image processing becomes complicated, the copying operation becomes complicated, and the image processing time becomes long.

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 provide an image processing system that can easily and quickly perform image processing such as image editing, short-range communication of image information, and long-distance communication at low cost. The purpose of this invention is to provide a processing device.

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

First, the multipath 30 and the case where the information is received and passed will be described. When the I10 processor m-1 outputs address information to the address/data buffer to-g, if the bus controller toS supplies the AL area code to the address/data buffer jo-4, the address/data buffer 0 → latches address information into the address buffer. Further, when the bus arbiter 10-2 acquires the right to use the multipath 30 after latching, the bus arbiter tO-J transfers the address/data buffer tO-
The address/data buffer to-p+ outputs the latched address information to the multipath 30. Here, DMA controller IO
is in write mode and multipath 3θ has been acquired, I/10 processor 1rO-/ outputs data information to address/data buffer to-4I, and address/data buffer tO-a , upon receiving the DEN signal from bus controller 10-3, outputs data information to multipath 30. On the other hand, when the DMA controller 10 is in the continuous output mode, the address/data buffer rO-9 reads data information on the multipath 3θ and supplies the data information to the I10 processor 10-1. Reading of data information by the I10 processor 10-/ is performed by the disk memory 9, which is the data transfer destination.

The operation of p1 buffer tO-a is also substantially the same as described above, but in this case, the AEN signal from bus arbiter 10-2 is not required when outputting address information to internal bus rH. Also, whether or not to output data information to the internal bus x toz is determined by the PDE by the bus controller to
As the 6-disk memory 90 determined by No. 4,

Data bus to-i4! o 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 sequentially enter the disk controller circuit. They are distinguished by their output. 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 the information about the DMA controller to and the disk memory?

The program space for communication between the CPU and the DMA controller 10 and the 00000h 0tFFF alley are assigned to the work RAM space of the CPU circuit block/θ.

Here, each address space will be explained.

The program memory space is RA)/110 that stores a control program for the device of the present invention in the CPU circuit block 10.
-3 memory space.

The bank space of the buffer memory has a capacity of ff?j kilobytes from 100OOHTF to EFFFF) ('iS:), but as mentioned above, the storage capacity of the buffer memory circuit block is /9tllrqo bytes,
It is not possible to store everything in the bank space of the buffer memory. Therefore, the buffer memory space is divided into three banks,
That is, it is divided into bank O, bank/, and bank 2, and the bank is switched by a bank switching signal outputted from the CPU circuit block 10 through 13 signal lines (see Figure 4! and Figure 6-2). The specified bank is then assigned to the memory map as shown in the r-th figure. This division will be explained below.

The communication program space is within the CPU circuit block/θ (

(7) Among them, r kilobytes are used. Also,
The work RAM space is 32 in the CPU circuit block 10.
Two kilobytes are used, which is obtained by subtracting I kilobytes used for the communication program from the kilobyte RAM 10-J.

9-/Figure is inside buffer memory circuit block x (7)
The address map of buffer memory n is shown. This buffer memory n has the ability to store information obtained by decomposing an A41 size (J97 rMnX 10 circles) document into 6 pixels per lrm. Leader club! OO main scans the Al size original in the vertical direction (in the direction of J971m), and then performs the next item C.
OD! 70. ! lrO and! 90 decomposes into 6 pixels per 1III11 and supplies 471.2 bits of pixels per 1 scan to the image processing control section 100. Further, the reader unit 200 sub-scans the document in the width direction (@210 mm direction) and uses the CCDj! 70,110 and! Since the laser scans 74542 lines per InI11 in this direction as well, the document is scanned for 3360 lines in the width direction. Therefore,
The Al size original is decomposed into 9447J0 bit pixels, and the image processing control unit 100 stores 17! - Bit pixels are supplied serially 33 times 0 times.

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

First, send an A4c size document / tm x / mm
(D square) Divide into unit blocks and consist of 42370 blocks. One unit block has 16 bits and /6 lines, that is, 1. If image information of ZSt bits exists, and 16 bits in the vertical direction are taken as an l word, and one address is given to the l word, one unit block will be composed of pixels with an address of /B. . The first line, that is, the first scanned document!
Serial image information of 4!71.2 bits for a line is divided into pixel groups of 76 bits each corresponding to the width of the document in the vertical direction, and is supplied to the image processing control unit 00, and is first transferred. The coming 74-bit pixel group is o in buffer memory n.
ooooom, the next /bu bit pixel group is OOOIOH
It will be stored like otaroHti place.

The addressing of each line to the buffer memory n is as follows:
C'PtJ circuit block/θ is address Karan 12/-
This is done by setting the initial value to 6.

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 every 76 addresses from the initialized address.

Next, for the image information of 4'7j Kobitsushi for the second line, do the same thing as for the 7th line, from 0000/T@ ground to 0
/, 2r/Il'a are stored. In this way, l! from the first line to the 1!3t line! J6 line (9dmm in width direction) from oooooom ground to 6FjF
The data is stored at address FH, and this address space is designated as bank 0 on buffer memory n.

Second, first. ! Make 7!36 lines from tJ7 line to 3072nd line the same as bank O and yooooom
This address space is stored as bank l on buffer memory n. Furthermore, the 3073rd
EO the 211th line from the line to the 3360th line
It is stored from the OOOQ area to the PIIE/Tanman area, and this address space is used as a bank code on the buffer memory n.

As described above, if the method of storing 1 word of image information with an address is used, A4! This means that the entire area of the original size can be stored. As a result, when the operator specifies the image processing area for each vagina using the console section -〇〇, when registering the specified area in the disk memo 1J90, the DMA can be processed by simply setting the start address and the end address of the specified area. The image information can be transferred at high speed without using the CPU circuit block/valve.

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 whose length in the vertical direction is 1, it is only necessary to set the address of the CPU circuit circuit button 10 three times.

Furthermore, since the address corresponds to the position on the manuscript image in units of columns, when editing the image, the operator only has to specify the position on the manuscript in units of units, which is convenient. In this embodiment, a CCD j; 70. ! Since 10 and 190 were used, it was decided that 16 bits in the vertical direction correspond to 1 address, but the number of bits corresponding to 1 address depends on the CCD.
It goes without saying that other numerical values may be used depending on the abilities of Jio, 5iro, and 190, and the same effect can be obtained even if the address is set in units other than units of battle, such as units of inches.

It is a megabyte. In other words, t bits of data are divided into 10
6 pieces can be accessed, and when accessing /l bit data, it will span the first address, so in this case, as shown in Figure 9-2, every 7th address is accessed for the lt bit data. Consecutive addresses are allocated, and 74-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, the multipath 30
When accessing the buffer memory 〃, as mentioned above, the address converter 1-f in the buffer memory circuit block J converts the address in the word λ into the address 9-1.
Convert to the address in the diagram. This address converter makes it possible to set the address area of Batza memory n on any address space.

The method of converting image information into Gofu No. 2 and No. 2 using this system and transmitting it to other systems is based on CCITT's T
However, in applying the T,# recommendation to the present invention, the following points should be considered.

(1) In the device of the present invention, the vertical direction (J97 m direction) of an A4I size document is 1 line, and the resolution is /j
bits/mm, the maximum run length, that is, the run length when the l lines are all white or all black, is 0712, which is the maximum expression range λ6 of the extended dish code (−*sao + ts).

O) In the device of the present invention, the parameter K is set to infinity.
Transmission is performed using the dimensional encoding method.

In other words, A4! For a document of this size, the first line that is first transferred to the DDX interface 10 is immediately encoded, and then the remaining 3339 lines are plate encoded.

Regarding point (1), the reason why the length direction is set to l line 2 is as follows. In other words, (by reducing the number of transmission lines, the transmission time can be shortened, and (
1) By reducing the overall moving distance of the sensor in the sub-scanning direction in the reader section jOO, the reader section jOO is made smaller.

Regarding point 0), the reason why the parameter K is set to a large value is to save the time of repeating plate encoding each time by setting the parameter K to a small finite value, and the parameter K can be set to an infinite value. The reason is that the image information to be transmitted has already been binarized by the COD driver M and once stored in the buffer memory, and the parameter K
This is because the meaning of minimizing the reading error is lost by setting the value to a small finite value.

The process of transmitting image information from this system to another system via DDX @Ij[1r00 will be described.

The image information for 1 line 2 minutes (4I712 bits) transferred from the mass and buffer memory n via the signal line /37 is transferred to the line buffer via the data/clock interface 60-/ and the write switch 60-3. to-4
I, to-s or to-a.

This image information is synchronized with a /θ megahertz (MH2) clock signal,
Line buffer tO-a at bit transfer rate.

60-! or ≦0-1. In other words, the transfer time of the image information of the l line is 4!7! . λfig.

The image information of the first line that is transferred first is transferred to the switch 6.
0-3, the image information is first supplied to the line buffer to-p, and when the line buffer to-q finishes storing the image information of the seventh line, the switch 60-7 opens the gate for line buffer ≦0-. , close the gates of line buffer 40 and 10-≦, and transfer the stored image information to RL.
The image information of the seventh line is supplied to the counter 10-, for which the white and black run lengths are counted and further run length encoded.
The H/MR converter 40-10 converts it into a ■ code.

While the line buffer to-e is outputting image information, the switch 40-3 closes the gate to the line buffer to-a and closes the gate to the line buffer to-a and closes the gate to the line buffer to-s. It opens and supplies the second line of image information to the line buffer tO-S. If all the image information of the first line is encoded, the image information of the 1M2 line is supplied to the RI and forward/reverse counter 60-7 by the switch ≦0-7, and the relative information from the seventh line is The pixel change positions are counted and encoded by the RL (c) T/h/m converter to-10. The image information of the third line transferred to the line buffer 10-1 is also processed in the same way as the third co-line.
≦To the O line, to the line no. 4 I, to
The image information output from z and ≦0-≦ is RLiE
/ RL←W switch 60-10 via reverse counter 60-7
and is MR encoded.

Next, the run-length encoded image information supplied to the RL→■1/Mm converter 40-10 is plate encoded or quadrature encoded and compressed.

As mentioned above, in the apparatus of the present invention, the maximum run length is 7S, which exceeds the maximum expression range of the extended dish code, 242J. Therefore, the deer code is further extended by the following method.

(1) Run length RL (In the case of StO, it is represented by the usual dish code. In other words, in the case of RL (#, it is represented by seven terminating codes. 61≦<<, 2sto
The case is represented by one make-up code and one terminating code.

The meaning of each signal flowing along the signal line interconnecting the image processing w0 and the DDX interface ≦0 shown in FIG. 12-1 will be explained.

Figure 12-2 shows each signal, its name, and image processing unit 10D.
FIG. 3 is a diagram showing the direction (arrow) of a signal between DX interface≦0. Here, FG and 8G are respectively
This is a safety ground wire and a signal ground wire. Call request signal (
CRQP) is a signal in which the image processing unit IO requests the DDX interface 60 to connect (call) with another system, and this signal is deenergized at the same time as the connection raw signal (CND) is activated. , and also the non-connection signal (NRYD)
When it is activated, it is treated as invalid. A call signal (CIP) is a signal sent by the DDX interface 10 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. CNQ is invalid when it is necessary to seize the line.
is energized, and de-energizing CNQ will disconnect the line.

The non-receivable signal (NRYP) is activated when the image processing unit lθ cannot be in a state where it can transmit or receive within 6 seconds. Indicates that the line cannot be connected when the NRYDI or DDX line lOO is in an active state, or when the not ready switch of the NCUrO is activated. This NRY line is always energized or deenergized depending on whether the line connection is disabled or enabled, respectively.

Further, if CRQI'# (CND is not activated even after a certain period of time has passed after being activated), the image processing unit 10 determines that connection is not possible.

CND is activated when CNQ or CIP is activated, and when the communication conditions between this system and the other communication partner system (partner station) are established, 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 (RDS) and ready-to-receive signal (RDR) are sent by the image processing unit/
Indicates that θ can be in a state where it is possible to transmit and receive image information for one A4' size document 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 configured to transmit and receive wB image information, respectively;
It is determined by looking at the 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 is now ready for transfer in transmit or receive mode.

The transmission data request signal (RQS) is activated and deactivated at regular intervals, and the DDX interface 60 requests the image processing section 10 to transfer 7542 minutes of image information.

When RQIII is activated, the image processing unit lθ activates the transmission data valid signal (SVA) and sends 7 lines of image information (
SDT) is transferred. RQS is de-energized upon completion of its transfer. The RQS repetition period is set longer than the minimum transmission time. SVA is activated in response to RQS, indicating permission to sample SDT in synchronization with the transmission clock (BcK), and deactivated upon completion of SDT transfer. The RVA is activated at regular intervals, and the DDX interface 10 receives and decompresses 754 signals from other systems.
Request to receive 2 minutes of image information (RDT),
Indicates that sampling is allowed in synchronization with the reception clock (RCK). The repetition period of RVA is R
It is similar to QS.

8DT and RDT are image information transmitted and received in black and white, SCK and RCK, respectively.
are the sampling clocks of SDT and RDT, respectively.

In the device of the present invention, when transmitting between this system and another system on DDX times @ 100, the transmission direction is the system that is the calling side (calling side station) and the system that is the called side. (Called station) compares RDS and RDR and determines as shown in Figures 1 and 3, thereby preventing errors in the transmission direction. In other words, in Figure 1)3, the energized state is indicated by 0, the transmission direction is indicated by an arrow, and the deenergized state and the transmission disabled state are indicated by x.
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 in combinations of RDR and RDRryv of both the calling side and the called side stage personnel + RDRryv + other than the above.

FIG. 12-4I shows an example of a procedure for transmitting data between a calling station and a called station.

Here, ID8 is the transmission function identification signal, which is the transmission function of the calling and called stations, that is, RD
This is a signal that informs S and RDR of each other. For example, the transmission format is "0000 RDR
The t bits of RDR/0" are transmitted sequentially from the most significant bit to the least significant bit, and both stages are divided into the main and RDR of this system and the RDR and RDR of the other station.
From this, the transmission direction is determined as shown in Figure 1J-3.

RDY is a transmission preparation completion signal, and its transmission format is, for example, "000/00IO" with ID
8, indicating that the transmission and reception of image information for seven originals in the transmission direction determined by IDS communication has been completed.

Ml/ is the dish-encoded image information of the first line, MRko~MRnJuno()≦n≦3340) is the image information of the first to n+/th lines that are dish-encoded, and MHn is the dish-encoded image information. The image information of the nth line and the image information of the MRJ 3
, g O is the MR encoded image information of the n+th line to the 3360th line, and MH/~MR3,? 4ff
Image information for seven A41' size originals is shown.

RTQ is a retransmission request signal, and if there is an error in the received l-line image information, that is, when the called station demodulates the transferred image information, the l-line length is O or '1712 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
T by CI TT, 4! A signal obtained by adding 7 to the line end code EOL in the recommendation is transmitted to indicate completion of transmission of one image 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 connection, the calling and called stations begin serially sending IDSs to each other, repeating this transmission at least three times until they 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 the own station is ready, both stations send RDY at least three times until both mWs are completed, and when both stations are ready and RDY is sent from both stations, that is, at time B. At , the called station enters the receiving state without sending control signals to the calling station, and the calling station enters the transmitting state.

In the transmission of image information for one Al-sized original, for example, if a transmission error occurs in the image information of the nth line at time E, the stage number on the called side will be sent to the calling side station. RTQ is sent, and in response, the calling station encodes the image information of the nth line and sequentially encodes the image information from the n+/ line to the 3360th line.
R encode and transmit.゛... When the transmission of the image information is completed in this way, the calling station sends an RTC to the called station, and then both stations send ID8 to each other, and at this time, as shown in Figures 1 and 3. If the transmission conditions are met, then other image information is transmitted and received from time point C. Conversely, if the condition is not met, they mutually send DCN and disconnect the line.

If the transmitted VIDEO signal is command information, a command identification code is added to the beginning of the information, and the command/image identification circuit 70-3 removes the hood and identifies it as command information. Further, in the case of image information, the CLK number has a predetermined frequency (for example, Saw, jMH2), and the command/image identification circuit 70-3 identifies it based on that frequency.

Waits for input to accept the QUEST'' key.

Edit station lOO operates in two main modes: echo mode and edit mode. The echo mode is a mode in which characters input by the operator through the console unit 200 are transferred as they are to the image processing unit 10, and characters transferred from the image processing unit 10 to the editing station lOO are displayed on the CRTJOO as they are. The edit mode is a mode in which execution commands are given to the image processing unit 10 for creating and modifying the approval file. In this mode, the characters input by the operator are first processed by the editing station control unit 1I.
Temporarily stored in RAM 14 in SO, the operator can use the CRTJ.
After being arbitrarily modified on OO, it is transferred to the image processing unit/θ. Also, in the edit mode, data from the disk memory 90 is sent to the editing station control unit via the image processing unit/θ. The period during which the application file transferred to O is received is particularly set as command mode.

FIG. 1 shows the operation of the editing station control unit ljO when there is key human power in each mode. First, the mode is determined in step SA, and if it is determined that the mode is echo mode, the process proceeds to step SB, where the character echoed back from the image processing unit 10 is transferred to the working area, ? /11) and moves to step SG to return to the normal routine shown in FIG. If it is determined that it is the edit mode, the process proceeds to step SC, and since the working area 310 is being used by the screen editor in this mode, the character is displayed on the user input area 330, and the process proceeds 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 judgment is negative, proceed to step SE and store the transferred characters in the RAM.
Iil+ith Ml& is applied to Ltj, and the process moves to step SG.

By instructing the "REQUEST" key, the process advances to step S3, where the m-collection station tioo is set to echo mode, and in step S<t, it outputs an image editing block gram activation request signal to the image processing section/θ. . Next, in step S3, the startup of the image editing program is confirmed, and if the determination is negative, the process moves to Stellaf S Hiro, and if the determination is positive, the process proceeds to step 84. In step S6, CR
For example, the screen of T3oo is completely black, and the message area! '0N-LINE' is displayed in green letters on 4IO to notify the operator that the request to start the editing program has been validated, and 'ECHOMODE' is displayed in mode display areas J and ?0. , edit X + - inform John 1700 to operate in echo mode,
A command input is awaited in step S7.

In step S, the input of the command key input from the console unit -〇〇 is judged, and according to the judgment result, steps S/θ, 8/3. Migrate to Sa, 825 or S3.

In the echo mode, (since the screen edit function of JtTJOO does not exist, if there is an input for the key group 2 keys 9 related to screen editing, it will be processed as an invalid input in step S10, and the input will be processed 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.

If a command character in the key group 2λ is input, the process advances to step 8/4 via step S15.
The input command is transferred to the image processing unit/θ (iog), and the system operates according to the command. For example, the second? -2 As shown in Figure 2, when you press the "RE" key, the characters "RE" are displayed on the screen 30, and the carriage return key is pressed. By indicating 1t7, a reader drive signal is supplied to the reader unit SOO, and the document image is read.

ED'' is displayed to notify the operator that the coordinates have been validly input, and the information about the number of meters of X(?7 and YO) is transferred to the image processing unit IO.

Once the area specification or position specification is completed, the process returns to step S, and the editing station Toshio waits for input from the console unit IQ again, and depending on the input of a new command, displays the display before executing the area specification or position specification. The specified command and the specified spawn are displayed on the working area 3〕θ as shown in Fig. If the operator instructs another command key before performing a drifting input, the state of waiting for input of coordinates for area specification or position specification is canceled, and the @area specification key or 1 position specification key is pressed. The command that was displayed before the instruction is displayed in the working area 310.

To release the editing station q-oo from the control of the image processing section io and cancel the online state, input the KL command using alphabet keys 1:13. At this time, the process proceeds to step 8.26 via step S3, and the character information of "KL" is output to the image processing unit IO,
That Ii! Request termination of the iI image editing program and proceed to step 8.27. In steps S and 2, when the editing station control unit IIO detects that the editing program of the image processing unit IO has not finished,
A negative determination is made, the end input is invalidated, and the process moves to step S7. Further, if an affirmative determination is made in step S, the online state is canceled and the process moves to step S/.

When instructions are given to a group of keys related to application files, that is, the ``routine work'' key, the 1 application file call'' key, and the ``application (//) cage date file creation'' key. As shown in Figure 2, the editing stage screen is set to edit mode in step S30.Here, the ``Create Application File'' key is used to create a new application file. The "Application file call" key is a key for instructing when calling and modifying an application file registered in the disk memory 9θ, and the "1 fixed form" key is a key for instructing when an application file registered in the disk memory 9θ is called up and modified. This key is used to instruct when the command sequence is called and sequentially transferred to the image processing section 10 for image editing.

When these keys are input, input determination is made in step S3/ for each case of routine work, application file calling, and application file creation. In the edit mode, since it handles application files, it is essential to specify the file number. Therefore, in any (//,?) case, first in step 83.2, the editing station control unit 4ISθ makes the screen of the CRT 300 blue, and displays @BiWTER in the message area 3ψ.

Return the screen of o to black, and execute the following process in each case according to the respective processing procedure.

First, we will describe the procedure for creating the 7th aisle of the app cage.

Step S? , 2, when the application file number is input, in step S, the editing station controller DA sets the message area to 3%.
ER Corridor NU Bi is displayed to prompt the operator to create an application file. The operator then makes the cursor 30:l blink in the upper left corner of the working area 310 and waits for command input, and then the operator sequentially inputs a desired group of commands to create an editing program. By inputting one command and adding a carriage return, the command is sent to the editing station controller 11k.
The data is transferred to RAM 4I# in RAM 4I#, and simultaneously displayed in the working area 310. In this way, the input command group is stored in RAM 41. Since it is stored on tA, by instructing a group of font edit keys, you can perform screen editing functions, that is, erasing the line or character where the cursor 3θ is blinking, inserting a new line or character, and You can move 30 cursors, etc. If the creation of new lines in the editing program exceeds the number of lines that can be accommodated in the working area 31θ, the working area 3
10 is scrolled up one line at a time, and cursor 3
The tooling area J1 can also be adjusted by moving up and down.

When creating an application file, area designation input processing is performed in the same way as in echo mode, but position designation input processing is performed as follows. The position specification input when creating application 7 isle is LO
This is related to the input of the coordinates XO and YO of the ADH (...) command that is input next to the (...) command, so make sure that the LO (...) command is input in advance, and , searches for CR(...) from the command group that has already been input, and extracts the coordinate information XO#YO, X/ and Y/ of the same file number. As a result, if the S information cannot be extracted, the L?th? -, 2 Perform the process shown in the figure. On the other hand, if the coordinate information can be extracted, Section 3

RT? For example, assuming that the left side of the screen of θO is white, an area 3/A defined by the coordinate information xo, yθ, X/ and Y/ within that plane is A and ? /? A is displayed in red, and the file number FN of the image file is also displayed in the upper left corner of the area. On the right side of the screen, this is colored blue, for example, and within that plane there is an area 3/l determined from the changed coordinate position information XO' and YO' and X/ and Y/.
B and? 77 Display B in green. In addition, a rightward arrow, let, is displayed in the center of the screen to indicate the movement of the image. TRACEM
"ODE" is displayed to notify the operator of the end of tracing.Then, when the operator 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 depending on the application file currently being traced.

When creating an applicage file, as mentioned above, the image file number, the trii collection image area (X
O, TO, X/, Y/), change position of edited image (
In addition to specifying numerical values (Xo', Yo') and the number of copies to be printed, 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) Read the original by the reader unit 300 and store it in the sofa memory (-2) CR (N-o, F) (CR) File number N, area F ( XO, YO

(CR) Copy eight copies of the image information stored in buffer memory n.

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

Create an application file with the wjJ image position as P and the number of copies as S. In this way, the operator creates an ablination program, and when the creation is completed, the operator performs step S, ? Input the editing end key with +.

At this time, the process advances to step S35, and the editing station control S da SO sets the message area 3 da O to @8'I'0BE.
THIS COMMAND FILE 'i'" is displayed, and it is confirmed whether the application program stored in the R module 90 is registered as a file in the disk memory 90.The operator denies this message. When the 1N'' key is input, a negative determination is made in step SJA, and the editing station l/so exits the edit mode, disappears the screen 30/, and returns to step S3.

In response, when the operator inputs the 1Y'' key to request file registration Tr:, an affirmative (/j
O) After the determination is made, the process proceeds to step s3g, and based on the file number set in advance by the operator in step S3,
Editing station control unit 4t! iO sends an ED(...) command to image processing unit IO to obtain permission to transfer the application file. If a file with the same file number as that file number is not registered on the disk memory 90, step 8J? A negative determination is made in step SQ, and the process proceeds to step SQ, where the image processing unit lθ permits the editing station control unit lI&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. Mail f @ from the processing unit 10 to the editing station control unit 4t! 0, if a signal indicating that a file with the same file number as the created file has already been registered is transferred, step S
An affirmative determination is made in step 39, and the process proceeds to step 54Ii.
For example, @FILE ALR in message area 3
EADY REGISTERgD, DELETEO
LD? ” is displayed and the corresponding (/) in the disk memory 90 is displayed.

ENTERF'ILE NO
, AND CARRIA (JRETURN),
Prompts the operator to enter a new file number. When the operator inputs a new file number, the process moves to step 83g.

In addition, T! for the ED command! If the response from the fJ image processing unit IO is other than the error code @Og, the editing station control unit 1Izo determines that it is impossible to transfer the application file, erases the screen 30/, shifts to echo mode, and closes the message area. 31IO displays the corresponding error code.

Next, the processing procedure when an application file call key is specified will be described. When the file notification number is input in step S3, the editing stage target θθ is set to command mode, &! The collection station control unit 3θ is set to XR (...) according to the input file number.
The command is output to the image processing section 10. Therefore, in step S'lA, the image processing section 10 calls the corresponding application file from the disk memory 90, and stores it in the RAM.
Forward to Toshioto. When the editing station control unit 30 completes receiving the application file, it proceeds to step S.
The edit mode is reset at /47, and then the process moves to step SJ3, where the application file is modified by deleting and inserting lines and characters using the same procedure as for creating the application file. If an error code is sent from the image processing unit IO, the editing station control unit 3o erases the screen of the CRT 300 and returns to echo mode, and also displays messages in the message area 34IO and the status display area 310, respectively. , an error hood, an error message corresponding to the error hood, and a status are displayed.

Next, the procedure for routine business input processing will be described. When the operator instructs the ``1 routine work'' key and inputs the file number of the desired application file, the editing station control unit θ will move the specified file to the RAM da!r6 in the same way as when calling an application file. (Step S32. S to S+7). Then, in Step S4tg, the editing station control section 3θ is stored in the RAM.
Search the command group stored in 4'j& from the beginning to find variables N, F, P, and S. Step 81I?
If, as a result of the search, those variables are not found, the process moves to step S:3, and the command group of the application file is transferred one by one to the image processing section 10. On the other hand, if it is determined that one variable matches, step S! Proceed to O.

In step SRIO, the editing station controller 41
When Sθ first discovers the variable N, the message area of CRT30θ, ? A comment is displayed asking the user to enter the file number in lI0, and the variable N is replaced with the numerical value input by the operator. Next, when the variable F is found, it is displayed in the message area J4tO so as to specify an image area, and the variable F is replaced with the values XO, YO, X/ and Y/ input by the operator. Next, when a strange IP is discovered, a message area 3410 is displayed asking you to specify the image position.
Replace the variable P with the values XO' and TO' input by the operator, and if the position specification input is related to the combination of CR (...) and LO (...) commands, the The processing shown in Fig. 3-3 is performed, and if it is related only to the LO(...) command, the processing shown in Fig. 3-3 is performed. Also, when variable B is discovered, message area 3
1Io displays the desired number of copies to be input, and WISTr: is replaced with the numerical value input by the operator.

In this way, when the operator replaces all the variables in the command group with numerical values, the process proceeds to step S, t/, where the editing station control unit <sho performs the slicing process as shown in Figure 3-6 to change the editing form. is displayed on the working area 310, and then, in step 83.2, "@OK'i'" is displayed on the message area 3110 to confirm with the operator whether the image editing form is as desired. The operator
For example, if you deny the confirmation by pressing the @N" key, the edit stage (/, 2.t) John control unit 1lro erases the screen of the CRT 300,
The process moves to step SJ7. On the other hand, if the operator confirms this by instructing the *Y IT key, for example,
Proceeding to step 81.2, the editing station control unit 4
Igo saves the screen as it is, sequentially transfers the command string to the image processing unit IO, and executes a predetermined program.

The image processing unit IO echoes back the transmitted command character to the m collection station control unit 4tso,
The editing station control unit 1Iso displays the command in the status display area 360 to allow the operator to confirm the status of the system. When the image processing unit 10 finishes executing a series of commands, the editing station control unit l/-30 performs step S, ? ? , complete routine work, and return to echo mode. If an error occurs in the process of command execution by the image processing unit 10, the editing station control unit 30 interrupts the command transmission and
RT? Disappears the Oθ screen, displays an error hood in message area 3, and shifts to echo mode.

In addition, in the processing in the above-mentioned edit mode, that is, command file creation, command file calling, and routine work processing, the operator performs step S33 or step S! For the subcommittee which instructed the edit reset F key during the O input process, the CRT Joo screen is erased intoxicated, and the process moves to step S37 to return to the echo mode.

Also, if there is an end input, it outputs a KL command to the image processing unit IO, and sends the image processing unit IO and ail collection station 1I.
The online state with 00 is canceled and the process moves to step 8.2.

(?) Image collection and transmission using the reader operation unit In this system, in addition to reading the original image using the reader operation unit kkO shown in the first diagram, 1 also performs off-campus communication and image editing using application files. It can be carried out. As mentioned above, the reader section 30.theta. operates in the copy mode and the edit R mode.

Effects As explained above, according to the image processing apparatus of the present invention, the following 2-! You can get more results.

(1) A reader unit that reads the IJX fJ meeting, an image processing control unit that controls image processing and stores processed images, an editing station that edits image information, and other components on the optical fiber network with this system. An optical fiber interface that performs mutual communication of image information with the system, a DDK interface that performs mutual communication of image information between this system and other systems on the DDX 1I1F6'l network, and a DDK interface that performs copying of image information. Since the image processing device of the present invention is configured with a printer section, image information can be captured,
Processing of image information such as image project collection, short-range communication of single-image information using optical fiber networks, long-distance communication of information using DDx lines, and copying of image information This can be done easily, quickly, and at low cost.

(j) 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 in the device of the present invention and the Hikari 7 system to this system via the Hikari 7 AIPA cable. By switching the flow of image information transferred to the buffer memory, optical fiber interface, and printer section, it is now possible to select one or more of them and transfer them to each section. Copies can be processed in parallel, and image processing time can be shortened.

(, y) Image information transferred from other systems on the DDX line network via the DDX circuit feed and DDX interface is stored in the buffer memory, so regarding the processing of the image information stored in the buffer memory. ,
You can obtain the same effect as the upper product (ko).

(4') When communicating image information between this system and other systems via the DDX UfiJ line network, documents of a predetermined size must be exchanged between this system and other systems within a predetermined time. A signal RDS indicating that the image information can be transmitted and a signal RDR indicating that the image information can be received are sent to each other, and in both systems, the transmission direction of the image information is determined from a certain combination of the RDS and RDR of both systems. This makes it possible to prevent burdens on the transmission direction and to shorten the transmission time of image information using the DDX line.

(j) The DDX interface performs run-length encoding of 7242 minutes of image information in the vertical direction of the original image, and further performs data compression using the Tt-dimensional encoding method of the 7242 minutes of run-length encoded image information. The ten-length length of 7242 minutes of image information is 26.2
If the length exceeds 3, following the make-up code corresponding to the run-length length 0, add one make-up code corresponding to the required run-length length, and then add one terminating code. Since data compression is performed, when communicating using a DDX line,
Since the total number of lines of the original image to be transferred can be reduced and data compression can be performed efficiently, the transmission time can be shortened.

(lh) When communicating image information between this system and other systems via the DDXIim line network,
The image processing control unit sends or receives a signal CRQP requesting connection to another system, a signal CNQ requesting supplementation of DDX re-hulling, and image information to the DDK interface within a predetermined time. A signal NRYP indicating that the image information cannot be transmitted and received within a predetermined time, signals RDS and RDR indicating that the image information can be transmitted and received within a predetermined time, and 7242 minutes of elevation information are supplied to the DDX interface. The image information SDT and the signal RQS indicating that the image information is in the valid period are transferred. Also,
The DDX interface sends a signal CIP to the image processing control unit indicating that a call has arrived from another system, and a signal NRYD indicating that the DDX@ line cannot be connected, indicating that the connection of the DDX line has been completed and communication is possible. Signal C indicating that
ND, a signal RQS that the DDX interface requests from another system, a signal RVA that requests reception of the 1-2 minutes of image information received by the DDX interface from the other system, and a signal RVA that requests the reception of the image information for 1 2 minutes after receiving it from the other system. The adjusted image information is transferred. These signal groups enable reliable communication of image information between this system and other systems.

(ri) When communicating image↑〃information via a DDX line, once the relationship between this system and another system is determined between the calling system and the called system, both systems inform each other of transmission conditions, and when the transmission conditions of both systems are met, they mutually send a transmission ready signal, the calling system starts transmitting image information for each line, and the called system monitors transmission errors for each transmitted 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 one-dimensional encoding method that one-dimensionally encodes the line in which the transmission error occurred, and then two-dimensionally encodes the following line. transmission is resumed. That is, image information can be transmitted reliably, and even if a transmission error occurs, the error can be quickly removed.

(lr) The optical fiber interface converts optical signals serially transmitted from other systems on the optical fiber network into electrical signals, and reproduces image recording commands and image information from the signals to control image processing. In addition, 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 ll! ]7 In a system that performs image recording, image information can be recorded without requiring any operation, and image processing can be speeded up.

(9) The image processing section (CI'U circuit) sends a status request to the black printer section, and the printer section notifies the image processing section of the status of the printer section in response to the status request. sends a recording preparation command according to its status, and the printer unit records image information in response to that command, so the artist processing information forming unit side can recognize the status of the printer unit. Image recording can be performed directly from the image forming apparatus, thereby making it possible to perform image recording effectively.

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

(/l) The image processing control unit sends a scan start command to the reader unit, and the reader unit responds to the command to document fi! Since it scans it@ and supplies the image information to the image processing control unit, it is possible to command the reading of the original r# image directly from the image elevation processing information engraving unit side, and this allows the image to be read. Reading can be performed efficiently.

<tS) The reader unit is equipped with a reader operation unit, and the application file stored in the disk memory can be started from the league operation unit, so that the standard Tsukishima of Iil supremacy can be easily performed on the reader unit side as well. .

(ta) Enable image information to be sent from the league operation unit to multiple other systems on the optical fiber network and DDK line by specifying the destination, especially when sending to other systems on the optical fiber network. for,
Since the number of copies can be specified for each destination, image information can be transmitted easily and quickly.

(The Shinji station at Information can be input easily.

(is) The 01 collection station is equipped with a display means such as a C"RT, and information for image editing and messages generated from the image processing control section are displayed on the screen of the CRT, so the operator can You can proceed with your work while interacting with the editing station, and you can easily create application files for image (g! It is possible to deal with this problem, and it is possible to efficiently collect pictures.

(/A) The command menu section of the ffa collection station has a command to start the reader section, and by inputting that command, the reader section can read the document image, so it can be used while editing images. When it is necessary to cause the reader section to execute a reading operation, the operation can be executed simply by operating the command menu section, thereby simplifying the image editing work.

(17) Since the command menu section has a command that allows you to select a dither pattern, such a selection can be made by operating only one command menu section.
) can produce the same effect.

(n) :2: When reading a document image, commands are provided in the mantle menu section to specify areas to be shaded and dithered in the image, greatly increasing image processing ability and making the work easier. It can be done easily.

(19) The command menu section has a command to start the printer section, and by inputting that command, it is possible to make the printer section perform an image recording operation, so that the printer section can perform a recording operation during image editing work. In cases where execution is necessary, the same effect as the first term (/l) 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 buffer the registered image file. Since a command for temporarily storing data in the memory is provided, image editing can be performed easily, reliably, and quickly.

(,2/) Since the area on the digitizer and the address of the buffer memory are made to correspond, image editing can be easily performed without error.

(〃) When editing images and creating editing programs, the CRT display screen displays what the operator will do next, so it is easy for operators with no experience in image editing to You can also understand the operating procedures,
Image collection can be done easily and quickly.

(3) # When editing images, etc., if the WfJ image editing area specified by the editing station exceeds the secrecy area of the device, a warning will be displayed on the CRT screen, so li! ii image collection can be performed reliably.

(-ri) When editing images, etc., an identification number is assigned to each designated area, and the area is displayed as a frame on the CRT screen, and the identification number is displayed within the frame. As a result, the operator can visually confirm the editing area, and therefore can easily and reliably perform image editing.

(Discussion) Since the execution form of the editing program can be traced on one screen of the CRTIilj, the execution form can be visually checked, and therefore not only the operator who created the editing program but also other operators can see the execution form in one screen. It is possible to easily and reliably perform the rules.

(, 2A) When creating a MM collection, you can input the number of recordings, the area of the 8th collection, etc. as variables (
Since the system can be made flexible, the system can be made flexible and the M image aggregation work can be easily performed.
