Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a digital image processing system for recording digital images after processing them.

Regarding the copying process of conventional electrostatic copying machines, attempts have been made in recent years to digitize paintings using digital electronic technology and to perform printing by adding various processes. Such a digital image processing procedure is stored as a program in a magnetic disk unit in the apparatus, and is called up and executed as needed. In this method, the program and digital image data are stored on the same magnetic disk.
The drawback is that recording and reproducing increases the burden on the central processing unit that manages the device.

The program editing department, which creates and edits programs, is used in conjunction with the digital image processing department.
The drawback was that it was not possible to create and edit programs independently. Furthermore, since it is necessary to connect the program editing section and the digital image processing section to exchange data, the device configuration becomes larger and the control means become more complex, making it difficult to operate the device. .

SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks, it is an object of the present invention to provide a digital transaction processing system that is simple in structure and easy to operate.

In order to achieve the object of the present invention, the program collection section and the digital processing section are made independent, and the program is transmitted using non-volatile memory. Therefore, it can be provided with the function of a key counter conventionally used in electrostatic copying devices, and has the characteristic that there is no discomfort when using it. Another feature is that programs can be divided into smaller pieces, making program management easier.

The present invention will be described in detail below using the drawings.

Figure ts1 shows the system configuration to which the present invention is applied, where l is an editing station, ko is a digital image processing unit,
3 is a nonvolatile memory. The program created at editing station l is written into nonvolatile memory 3. A nonvolatile memory 3 is connected to the digital image processing section 2, the written program is read by the digital image processing section, and the program is selected and executed.

- A collection station 1 is composed of an editing circuit 10, a display unit used when creating a program, an operating circuit 1, and a printer 13. In addition, there is a digital image processing unit, a system controller, a reader unit that performs digital data processing under the control of system controller J, and a communication circuit that exchanges digital data with other digital image processing units. - It consists of a printer that records digital images, an image collection circuit that performs processing such as positional movement, storage, etc. of digital partial sampling, and an operation circuit. Here, the printer is, for example, a laser beam printer.

The non-volatile memory 3 may be removably attached to the editing station 1 and the digital image processing unit.For example, a reader controller 1 reads the document, an image editing circuit λ extracts a portion of the image, moves the position, and prints the image to the printer n. Editing station/-L creates a program for performing a series of processes such as printing out data, and writes it into the nonvolatile memory 3. After writing the program, the volatile memory 3 is removed from the editing station 1, connected to the digital image processing section λ as needed, and the written program is executed. In this case, there may be a plurality of programs, and the programs may be selected and executed by the digital image processing section.

In this way, by making the operating program independent from the editing station l and the digital image processing section λ, management becomes easier when there are a large number of programs. As non-volatile memory 3, magnetic bubble memo IJ, 1JL erase F
A feature is that the reliability of the device is improved when solid-state memory such as ROM is used. In addition to the above programs, the nonvolatile memory 3 may also be used to store information such as the number of prints and billing information for each user. In that case, management of the device becomes easier.

By replacing the key/counter with a non-volatile memory 3 instead of the function of conventional electrostatic copying machines where the machine does not operate unless a key/counter is inserted into the machine, it is possible to manage the use of the machine. It is. Users who have used electrostatic copying machines can accept such a replacement without any hesitation since there is no significant difference in function or shape.

Conventionally, digital image data and the above-mentioned program have been stored on the same hard magnetic disk, making management of the data stored on the hard magnetic disk complicated. 1st
By configuring the system as shown in the figure, such drawbacks could be eliminated. Furthermore, since the devices are divided by function, the functions and configuration of each device can be simplified, which improves the reliability of the system and facilitates system service and management.

(referred to as F) consists of toys.

The I/Oio6 is connected to a display, a keyboard, an operation circuit 12 such as a @Ki tablet, and a printer 13 that outputs a list of programs, etc.

It stores an execution program that causes the image collection path 2q to execute according to the program contents, and executes the program written in the nonvolatile memory 3 in response to a signal from the operating circuit.

Figure 3 shows non-volatile memory 3 and non-volatile memory IJI/Fior.
The signal connections with and 207 are shown. The data signal SD is
A signal for sending and receiving data to be written or read in a non-volatile memory element, depending on the type of non-volatile memory element, 2
The number of signal lines used changes, such as one line. The memory type determination signal SK determines whether or not the nonvolatile memory 3 is connected, and if it is connected, the KEPR
This signal is also used to determine the type of nonvolatile memory element such as OM, magnetic bubble memory, etc., and information such as whether it is exclusively for M capture.

The memory write inhibit signal S□ is a signal used by the user to specify whether or not programs and data can be changed/erased in the writable non-volatile memory, and can be selected using a switch external to the non-volatile memory 3. There are seven days.

Control signal S. is a signal for controlling the nonvolatile memory element when writing and reading data to and from the nonvolatile memory 3.

The details of Figure 3 are shown in Figure 3. Here, 300 is a nonvolatile memory element, and 30/-30 are switches or jumper wires used to determine the type of memory. 301
is a memory write signal switch that can be set arbitrarily by the user. Non-volatile memory I/F loy and 2
R/-Rj of 07 is a pull-up resistor. As a result, the non-volatile memory 3 becomes the non-volatile memory IJ/i'
101 and θ7, the memory type discrimination signal SK and the memory write prohibition signal S are all high level signals, and the write is enabled when the memory type is set. 3/ is a data signal S, a memo 17 m type discrimination signal SK, a memory write inhibit signal S, and a control signal S. This is a connector in which signal lines, power supply lines, etc. are arranged. In Figure 814, non-volatile memory 3
Non-volatile memo+) shows the state connected to I/IF 101 and Ko07. Here, 3 is an indicator indicating that the nonvolatile memory 3 is in a writable state, and when this is lit, writing is not possible. Reference numeral 33 denotes an indicator indicating the read/write status of the nonvolatile memory 3. The indicator 3J uses, for example, a two-color LED, so that the user can know that when the green light is lit, it is in the face-down state, when the red light is lit, it is in the writing state, and when the light is off, it is in the inactive state. can.

In the example shown in FIG. 3, since the memory type discrimination signal SK is of the reference line type, it is possible to discriminate between types of states including the case where the nonvolatile memory 3 is not connected.

This allows for various memory elements such as electrically erasable FROM (EEFROM).

Magnetic bubble memory and mask ROM % can be used depending on the purpose. For example, highly versatile programs that are used in large quantities are masked ROM,
Individual programs for each user can be used as EKFROM, and large-capacity programs can be used like magnetic bubble memory. In addition, non-volatile memo corresponding to the type of non-volatile memory 3! Further versatility can be achieved by providing dedicated hardware for the I/F ior'' and 207. In this case, the non-volatile memory controllers 107 and 206 can be configured in advance according to the type of non-volatile memory element. , non-volatile memory I/F/(H and co07
All you have to do is switch and use the hardware.

In addition, instead of using the memory type discrimination signal only to discriminate memory elements ATB such as EEPROM, magnetic bubble, and mask ROM, it is possible to disable rewriting (irrespective of the memory write signal) even though it is originally rewritable. Alternatively, it may be used to determine whether a special program for service or factory check is installed. A specific example of signal value assignment of the memory type discrimination signal SK is f.
gt table.

The memory configuration of the nonvolatile memory element 300 in Table 1 will be described. Below is the program, &! Nonvolatile memory for gold data, etc.
#The data to be stored will be called a file. Second
The table shows an example of a memory configuration of a nonvolatile memory element.

Memory is roughly divided into two types. It is divided into an index part that stores information such as the name of the file and the physical start address of the data part of the file, and a file database 11 and an evening part number ζ that stores the actual program and data part of the file. The index portion is stored starting from a specific address such as the physical start address of the nonvolatile memory 3, and is used for file management.

Specifically, the file name, file size indicating the size of the file data portion such as 100 bytes or /θ block, file type indicating the type of program, billing data, etc., and indicating whether the individual file has been rewritten or not. It consists of write protection, a file/data start address that indicates the physical start address of the file/data portion of an individual file, etc.

Diagram IIZ shows the procedure for reading 7 isles from the nonvolatile memory J. First, when taking a file in the non-volatile memory J, the above-mentioned memory type discrimination signal SK is determined in step SP/θ, and the non-volatile memory J is connected (in this embodiment, the value of the memory type discrimination signal SK is determined). is other than tS). If it is not connected, the error 7 lag is turned on in step SP#, and the program that requested to read the file is notified that there is a reader 2~. Next, in step SP/ /, the memory type determination signal SK selects the nonvolatile memory x/vio.
It is determined whether r and λ07 have a hardware I/F for reading. If the cine can be read, the process moves to step E3P/t. In step SP/co,
Switching is performed inside the nonvolatile memory I/F 'ioz and Q7 to the hardware I/F corresponding to the nonvolatile memory element. In step SP/J, the index part of the non-volatile memory element is read, and in step SP/4 it is determined whether there are the necessary 7 files. If there are no necessary files, the process advances to step SP#. Step SP/
In j, the 7 eye of the index part of the corresponding 7 eye of the non-volatile memory element. Reads the file data start address and uses the file size at the same time to grab the file data part. At the same time, the Step 2 flag is turned off to indicate that the reading has been completed normally.

By following the above steps, the file contents of non-volatile memory 3 can be
Automatic reading is possible regardless of the type.

Figure 181 shows the procedure for writing to the nonvolatile memory J#ζ7 isle.◎If there is a file write request, at step SP-0, the same process as step 5 PIO is performed. If non-volatile memory J is not connected, step SP
Go to J/ and turn on the error flag. Step S
In Pco/, it depends on the write protect switch X and 301K. Determine whether the memory is a read/write-only non-volatile memory that does not accept the memory write inhibit signal using the memory type determination signal 5KJ.The use of the non-volatile memory only for marking is to provide information such as fees to the user, number of prints, etc. that need to be constantly updated. It is used to store a certain file, and the purpose is to prevent file updates from being prohibited by a memory write signal.In the case of a read/write only nonvolatile memory, step E3 is used.
Proceed to P2J. In step 5P2-2, it is determined whether the write inhibit switch is on or whether the memory type determination signal SKK indicates whether file writing is physically impossible, such as in a mask ROM. If writing is not possible, proceed to snap SP3/.

In step 5P2J, it is determined whether there is a hardware I/F corresponding to the same number as step SP// and the nonvolatile memory element, and if there is, the step 5pJe number advance circuit is switched. If there is none, proceed to step SPJ/. In step SP, the index part of the nonvolatile memory element is read, and the step SP core determines whether the same file exists.If the same file exists,
The write protection of the file index portion is read to determine whether the file is rewritable, and if it is not rewritable, the process proceeds to step SP3/.

In step SPJ, each file size in the non-volatile memory 3 is read and it is determined whether the new file write or update number will exceed the capacity of the non-volatile memory 3. If the capacity system is insufficient, step SP
Proceed to 3/. In step 5P30, an index portion and a file data portion are written in accordance with the file to be written.

FIG. 2k shows an example of program registration. In addition.

The program mentioned here refers to the program executed by the digital image processor. Specifically, one of the multiple programs stored in the non-volatile memory 3 is selected according to the operation designation from the operation circuit j, the contents of the program are read out and executed sequentially, and the υ~da U1 communication is performed. Circuit n, printer w, and m integrated circuit are operated according to a series of stored operating procedures. In this example of the calendar, program editing and registration are performed at editing station l, so the procedure shown in FIG. 91 is performed at editing station l.

The program edited with the operation circuit/co is stored in the non-volatile memory 3.
When you enter the command to register in , first step SP
In step #O, enter information such as the name and number of the program to be registered. It is read in step SPY/ whether the same program (file) exists in the nonvolatile memory 3. If the normalization reading is not performed in step SP, an error is displayed in step SP, and the program registration is ended.

In step S'P, it is determined whether or not there is the same program, and if there is, step 5pp41! Displays whether it is OK to update the Michi program. Next, Stella 7
' 5P41j is waiting for operator power. If there is a key power of ``-YKS'' in step SP 4, proceed to step SP 7#ζ, and if ``NO'', program registration is ended.

In step SP7, the program is transferred to the non-volatile memory 3I.
Check whether the writing is completed normally or not in step s.
Determine by referring to page 1.

In this way, the program written in the nonvolatile memory J is connected to the digital ijig I processing section.

It is executed by the operation input from the operation circuit j to execute the program. Next, the procedure for executing ProGuerra 4 in the digital image processing section will be explained using FIG. 70.

if, Step 5 Name of the program to be executed in pzo 9
Enter information such as number. In step SPj/, it is determined whether the input program is the basic program stored in the ROM 2oz. This basic program is the same in content as non-volatile memory 3, but
It is provided so that relatively simple operations can be executed even without the nonvolatile memory 3. for example,
This is a program in which the reader controller 1 uses a rough printer n to directly copy an original as in a conventional electrostatic copying device.

If the program in the non-volatile memory 3 is selected, the program proceeds to step SPj and the program (file) is loaded. In step f3Pj3, it is determined whether the program 2 has been read normally, and if there is an error, step S
'E'! t), displays an error, and stops program execution. If the program is read normally, the process advances to step SPj≠, and the program that has failed to be read is executed.

If the basic program is selected, step 5pz
Step SPY from i! Proceed to the memory type determination signal S
K is used to determine whether the nonvolatile memory 3 is connected. If connected, step 5Pj
If the non-volatile memory 3 is not connected to the digital image processing unit, the next step SP! In combination with step 4, this is a procedure to prevent the basic program from being executed, that is, to prevent the digital image processing section from operating. Step 5pst is a procedure for determining whether or not the basic program can be executed when the nonvolatile memory J is not connected. Specify whether or not. If it is disabled, the basic program will not be executed and step 5 will be executed.
Proceed to pit. Step 5 Pj4 l By making it possible to select whether or not to run the basic program when the non-volatile memory 3 is not connected, it is possible to add flexibility to the way the digital image processing unit is managed. The feature is that it is easy to use.
