DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image data correction method for correcting image data, and more particularly to a display (a screen on a display device, in which display in a multi-window display form is possible here). And an image data correction method for correcting the image data.

[0002]

2. Description of the Related Art In recent years, in computer systems related to core business in public business processing (for example, window business in a city hall), imprints, slips, and declarations are often managed as image data.

[0003] Here, it is relatively easy to manage "data with little correction" such as seal imprints and slips as image data and to display them on a display or print them with a printer.

[0004] However, "data with many corrections" such as declarations
For, it was necessary to consider the correction of letters and numbers to be entered. When making this correction, it is common to provide a screen for inputting characters, etc., to input characters, etc., and to manage the input contents as character data. It was difficult to manage the revised state.

[0005] Even if the image data can be directly modified, managing the history of the modification requires a large amount of image data in view of the necessity of holding a large amount of image data. This is difficult from the viewpoint that the disk capacity for storing the data becomes large.

[0006]

The above-mentioned prior arts (prior arts related to handling image data) include:
There were the following problems.

[0007] The first problem is that it is difficult to directly modify image data. For this reason, conventionally, when an operator intends to correct image data, it is necessary to open a screen for inputting characters or the like and perform a predetermined correction process.

[0008] The second problem is that even if the image data can be directly corrected, the contents of the correction, when the correction was performed, and the correction of the image data before the correction. It is difficult to manage and refer to the history.

[0009] The reason why there is a demand for managing such a revision history is that, in the paperwork performed by a human before computerization, a ledger or list is modified in red or a noteworthy item is marked with a sticky note. In many cases, such processing as pasting was performed, and when such a work is computerized, it is desirable to realize the same function as managing image data with a ledger or the like. Because.

SUMMARY OF THE INVENTION In view of the foregoing, it is an object of the present invention to implement correction of image data in a form in which a character character (character data) is superimposed (attached) on image data, and the corrected image data and correction history Efficiently eliminates the need for complicated work in the prior art (such as the work of opening an input screen and correcting image data) (simplifies the correction of image data) and saves the correction history. It is an object of the present invention to provide an image data correction method that enables management with a relatively small file capacity and enables a computer system that handles image data to be constructed in a manner closer to a processing mode by human work.

[0011]

According to the present invention, there is provided an image data correcting method for a computer system having a display capable of displaying image data and character data in a multi-window display. An image file to be held, a data file to hold correction data which is character data indicating the latest correction content corresponding to the image data in the image file, and a past correction content corresponding to the image data in the image file are shown. A data history file that holds history data that is character data together with information indicating the number of times the correction has been made, a correction count file that holds the number of corrections to the image data in the image file, Based on instructions Transferring the image data in the image file and the correction data in the data file corresponding to the image data to a memory, and, based on the history reading instruction, the history immediately before the window in which the history reading instruction was issued. A read processing unit that transfers history data in the data history file to be displayed in a window to a memory; and a display unit that displays the latest corrected image data obtained by combining the image data read into the memory by the read processing unit and the corrected data. A combined display unit for displaying in the upper image window, and displaying, in a history window on the display, historical image data obtained by combining the image data read into the memory by the read processing unit and the historical data, and a correction instruction and an image window The latest corrected image data above A correction processing unit that updates the correction data in the memory based on the correction contents to be updated, and a new data file having the correction data updated by the correction processing unit based on the update instruction, and creates a new data file.

FIGS. 5A and 5B show an image window and a history window displayed on the display 11.

The image window shown in FIG.
This is a window for displaying data (hereinafter referred to as “latest corrected image data”) in which image data and the latest correction content (character data) are superimposed on the display 11. In this image window, a history instruction area (an area for instructing history reading), a correction line instruction area, and a text instruction area are arranged together with the latest corrected image data. In addition, as an arbitrary area, a color instruction area for instructing a color of a correction line or a character or a font instruction area for instructing a size of a character of a text can be arranged.

The history window shown in FIG. 5B is a window displayed by an instruction (such as a click with a mouse) on an image window or a history instruction area in the history window, and includes history image data (image data and past corrections). This is a window for displaying contents (character data) superimposed. In the history window, a history instruction area similar to the history instruction area in the image window is arranged. In response to the operator's history reading instruction in the history instruction area, the immediately preceding history window (when the correction is performed immediately before the correction contents displayed in the image window or history window in which the history reading instruction was performed). (History window) for displaying the contents of the correction in (1).

Next, the operation of the image data correction system of the present embodiment configured as described above will be described.

First, the overall operation of the image data correction method according to the present embodiment will be described (see FIG. 4).

The control unit 21 receives an instruction from the operator through the input device 101 (see FIG. 2), determines the content of the instruction, and controls the following processing.

First, it is determined whether or not the instruction is a read instruction (instruction to read a file for displaying the latest corrected image data in the image window) (step S1).

If it is determined in step S1 that the instruction is a read instruction, the processing for displaying the latest corrected image data in the image window on the display 11 (image window display processing) is executed. Transfers control to the read processing unit 22 (step S
2) Wait for the next instruction.

On the other hand, if it is determined in step S1 that the instruction is not a read instruction, the instruction is a history read instruction (an instruction to read a file for displaying the history image data in the history window). It is determined whether or not (step S3).

If it is determined in step S3 that the instruction is a history reading instruction, a process for displaying the history image data in a predetermined history window on the display 11 (history window display process) is executed. Control to the read processing unit 22 (step S4),
Wait for the next instruction. When the history window is being displayed, if the operator wants to display the previous history window, the operator issues a history reading instruction to the history window.

On the other hand, if it is determined in step S3 that the instruction is not a history reading instruction, it is determined whether or not the instruction is a correction instruction (an instruction prompting additional correction of the latest correction image data). A determination is made (step S5).

If it is determined in step S5 that the instruction is a correction instruction, a correction process is performed to execute a process (image correction process) for correcting the latest correction image data displayed in the image window. The control is passed to the unit 24 (step S6), and the next instruction is waited.

On the other hand, if it is determined in step S5 that the instruction is not a correction instruction, it is determined that the instruction is an update instruction (an instruction to change the data file 32 reflecting the above-mentioned correction). Is determined (step S
7).

If it is determined in step S7 that the instruction is an update instruction, the data file 32 is changed to reflect the correction of the latest corrected image data by the image correction processing in step S6 (update). The control is passed to the update processing unit 25 to execute the process (step S8), and the next instruction is waited.

On the other hand, if it is determined in step S7 that the instruction is not an update instruction, it is determined whether the instruction is an end instruction (step S9).

If it is determined in step S9 that the instruction is an end instruction, the current image data correction processing ends.

On the other hand, if it is determined in step S9 that the instruction is not an end instruction, the process waits for the next instruction.

Second, the operation in the image window display process (see step S2 in FIG. 4) will be described.

In this case, as described above, control is passed to the read processing unit 22 based on a read instruction from the operator.

The read processing unit 22 stores the image file 3
The image data is read (transferred) from 1 (which image file 31 is specified by the read instruction) into an area a (image data storage area) on the memory 41.

The read processing unit 22 has image identification information indicating the image file 31, and sets data “0” (information indicating the latest correction content) in the history identification information. The file 32 is extracted, and correction data (correction content records) corresponding to the above image data is read from the data file 32 into an area b (correction data storage area) on the memory 41.

Next, the combination display unit 23 displays the image data in the area a on the display 11 and further superimposes on the image data the character data (text and correction lines) indicated by the correction data in the area b. (The latest corrected image data in which the image data and the corrected data are combined is displayed on the image window).

Third, the operation in the history window display process (see step S4 in FIG. 4) will be described.

In this case, as described above, control is passed to the reading processing unit 22 based on the history reading instruction from the operator.

The read processing unit 22 extracts a data history file 33 holding history data that is immediately before correction data or history data displayed in the image window or history window in which history reading was instructed,
The history data (correction content record group) is read from the data history file 33 into an area c (history data storage area) on the memory 41.

Here, the extraction of the "data history file 33 holding the previous history data" is performed as shown in (1) and (2) below.

When the window for which the history reading instruction has been issued is an image window, the number of corrections is recognized with reference to the number of corrections file 34, and the data history file 33 (the processing target and the It is assumed that the identification information of the image file 31 is included in the image identification information.
As a desired data history file 33.

If the window for which the history reading instruction has been issued is a history window, the data history file 33 having the number of pieces of history identification information smaller by one than the number of pieces of history identification information of the data history file 33 for the history window is desired. Is recognized as the data history file 33.

Next, the combination display section 23 displays the image data in the area a on the display 11 and further superimposes the character data (text and correction line) indicated by the history data in the area c so as to overlap the image data. Is displayed (character image data indicating the image data is displayed on the history window).

It is needless to say that a plurality of history windows can be displayed on the display 11. In this case, a history data storage area (an area corresponding to the area c) corresponding to the number of history windows is provided. ) Is the memory 41
Will be on top.

Fourth, the operation in the image correction process (see step S6 in FIG. 4) will be described.

In this case, as described above, control is passed to the correction processing unit 24 based on a correction instruction from the operator.

The correction processing section 24 corrects the latest corrected image data in the image window on the image window on the basis of the contents of the correction input to the image window on the display 11 by the operator via the input device 101. This correction is performed in the form of addition or deletion of character data (character data indicating a correction line or text).

The correction processing unit 24 updates the correction data in the area b on the memory 41 based on the contents of the correction.

Fifth, the operation in the updating process (see step S8 in FIG. 4) will be described.

In this case, control is passed to the update processing unit 25 based on the update instruction from the operator as described above.

The update processing section 25 creates a file having the correction data in the memory area b updated by the above-described image correction processing as a new data file 32. That is, a data file 32 having a modification content record group corresponding to the modification data, the identification information of the image file 31 having the image data of the area a in the corresponding image identification information, and “0” in the history identification information is created. I do.

The data file 32 up to that point is changed to a data history file 33. That is, a value obtained by adding 1 to the number of corrections in the number-of-corrections file 34 is set to the history identification information in the data file 32 up to that time.

Further, 1 is added to the number of corrections in the number-of-corrections file 34.

Finally, the above-described image correction processing (correction processing of the latest corrected image data) will be described in detail with reference to FIG.

When the operator corrects the latest corrected image data on the image window, the correction line indicating area is designated by a mouse or the like, and the correction position (the position of the corrected portion on the latest corrected image data) is specified by the mouse or the like. Is indicated, the character data indicating the correction line "-" is added to the latest corrected image data.

When a text pointing area is pointed by a mouse or the like, a correction position is pointed by a mouse or the like, and characters are input by a keyboard or the like, character data indicating the text at the correction position is input.

In the process of inputting the contents of correction from the operator, when the color of the text or the correction line is specified, or when the size of the text is specified, the image window is displayed. These instructions are realized by instructions to the upper color instruction area and font instruction area.

The correction data input / updated by such image correction processing, although displayed on the image data, is character data displayed on the image data, and is separated from the image data. Managed. That is, the image data is not directly corrected, and only the correction data, which is character data, is input and updated.

[0071]

As described above, according to the present invention,
The following effects are produced.

The first effect is that an image window and a history window are displayed on a display, and an image data file holding image data and a data file holding character data indicating the contents of correction are provided (image data and correction). The modification of the image data can be simplified by storing the modified image data in the image file and the data file separately from the character data indicating the contents).

The second effect is that, by holding the data file and the data history file, it is possible to manage the modification history as character data and to manage the modification history, and furthermore, to manage the files required for the history management. This means that the capacity can be reduced. By realizing such history management, from the viewpoint of the operator, it is possible to easily identify the revision history while referring to the image window and the history window, and to accurately grasp the location of the revision so far. And the efficiency of the correction work can be improved.

A third effect is that the response time at the time of updating a file (data file) indicating the latest correction contents can be shortened, and the file capacity for storing the corrected image data can be reduced. It is possible to do. The reason for this effect is that the image file is not directly corrected, but only the correction is made as character data, which is overlaid on the image data. (The file is divided into an image file and a data file, so the response time when updating the file can be shortened, and the file capacity can be reduced.) .
