DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a form processing apparatus for designing a desired form, and a program recording medium therefor.

[0002]

2. Description of the Related Art Conventionally, when designing a form for preprinted paper (standard paper) such as a slip, an invoice, and a report submitted by a government office, a form image read by an image scanner or the like is displayed on a display screen. When a form output form is input and designated on the form image screen as a background, an output form corresponding to the form is set. When the form data is input in the state where the form is set in this way, the input form data is allocated according to the form and printed out. By the way, when the form is set, the layout position and size are set for each print target item, and the item name is set. Here, the item name is converted into Kana-Kanji characters by inputting character string data from the keyboard, moving the finalized character string to the corresponding item position, displaying various item names as selection candidates, and arbitrarily selecting from among them The specified item name was set by moving it to the corresponding item position. Further, if the output form of the form is changed after the form is set, the correspondence between the item name and the item position is broken, so the setting of the form is restarted from the beginning.

[0003]

However, setting an item name for each item to be printed increases the amount of work, thereby making it difficult to design a form. Further, when a desired candidate is selected from a list screen in which various item names are displayed as selection candidates, it is not easy to find a desired item name from a large number of item names. Sometimes they made the wrong choice. On the other hand, if the output format of the form is changed, re-designing the form from the beginning will also reduce work efficiency, and even if only the changed part can be modified, the item name and item position There is a danger of confusing the correspondence with, and there is a risk of correction mistakes, so even when making partial corrections, it is necessary to perform correction work while confirming the correspondence relationship for all items, and it is not necessarily workability Could not be improved. An object of the first invention is to make it possible to easily set a character string such as an item name by recognizing a character string on the form image when setting the form based on the form image. That is. The problem of the second invention is that after designing the form based on the form image,
Even if the output format of the form is changed, it is possible to automatically correct the form based on the analysis result obtained by analyzing the changed form image and the form information before the change. .

Set as (4) When the form output format is changed, image data is cut out from the character string area on the changed form image and characters are recognized, and the recognized character string and the form information setting means are used. The set character string before the change is compared with the set character string, and when a mismatch is detected between the two, the set character string before the change is rewritten with the recognized character string after the change.
According to the first aspect of the present invention, image data is cut out from a character string area on a form image screen, characters are recognized, and a character string candidate index table is searched based on the recognized character strings. Is displayed as a candidate. When a desired candidate character string is selected from among them, the candidate character string is set as form form information corresponding to the character string area on the form image. Therefore, when setting the form based on the form image, character recognition of the character string on the form image
Character strings such as item names can be easily set.

According to a sixth aspect of the present invention, there is provided a form processing apparatus for displaying and outputting a form image read in advance when designing a desired form, and setting an output form of the form with the form image screen as a background. In the apparatus, form information for storing an item allocation position for each item defining an output format of a form, a character string in the item, and a relative value between the reference position of the character string and the item allocation position as form form information Storage means, when the output format of the form is changed, character recognition means for cutting out image data from a character string area on the changed form image and recognizing characters, and character recognition by the character recognition means A column is compared with a character string before change in the form information storage means, and when a mismatch between the two is detected, a character string reference position after change is detected.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a block diagram showing the overall configuration of the form processing apparatus. The CPU 1 is a central processing unit that controls the overall operation of the form processing device according to various programs. The storage device 2 includes an operating system and various application programs,
It has a storage medium 3 in which a database, character font data and the like are stored in advance, and a drive system therefor. The storage medium 3 is fixedly provided or can be removably mounted, and can be a magnetic medium such as a floppy (registered trademark) disk, hard disk, optical disk, RAM card, or the like.
It is composed of an optical storage medium and a semiconductor memory. The programs and data in the storage medium 3 are loaded into the RAM 4 under the control of the CPU 1 as needed. Further, the CPU 1 receives programs and data transmitted from other devices via a communication line or the like and stores them in the storage medium 3 or stored in a storage medium provided in other devices. Existing programs and data can be used via a communication line or the like. The input / output peripheral devices such as an input device 5, a display device 6, a printing device 7, and an image scanner 8 are connected to the CPU 1 via a bus line.
Controls their behavior. The input device 5 is a keyboard for inputting character string data and the like and for inputting various commands.
It has a pointing device such as a mouse. Note that the display device 6 is a liquid crystal display device, a CRT display device, a plasma display device, or the like, and the printing device 7 is a non-impact printer such as thermal transfer or ink jet, or a dot impact printer. The image scanner 8 is a stationary scanner that reads a form image by scanning on preprinted paper.

FIG. 2A shows a part of the storage device 2. A form image file 2-1 stores a form image read by the image scanner 8 in a form of one form and one file. It is read out when designing the form, and is displayed and output on a design screen. The form form file 2-2 stores and manages the form when the form is designed on the form image display screen with the form image as a background. FIG. 3A shows the form form file 2-2. 3 shows a data structure of the data. The form file 2-2 stores and manages “assignment item name”, “data print item”, “character string start position”, and “relative value” for each item on the form as form form information. . Here, as shown in FIG. 4, when the item name print area A in the form image display screen is arbitrarily selected and designated, the CPU 1 assigns a character string cutout frame B to the area and prints an image from this frame B. The data is cut out and characters are recognized, and the item name index table 2-3 is searched based on the recognized character strings to narrow down the candidate character strings and display a list. When a desired candidate character string is selected from this list screen, the candidate character string is set in the form file 2-2 as an item name for the item name print area A on the form image. The item name set in this way is “assigned item name”. The “data print item” is set to specify the data print area C associated with the item name print area A on the form image, and the upper left coordinate of the data print area is the layout position (XY) of the data print item. The size in the X direction from this allocation position is set as the X width, and the size in the Y direction is set as the Y width. In this case, the data printing area C
On the top, an item range frame D for setting a data print item is displayed as a guidance, and by arbitrarily changing the position and size of the item range frame D, a data print item (allocation) corresponding to the item range frame D is displayed. Position and size) are set. "Character string start position" indicates the upper left coordinate of the character string cutout frame B, and "relative value" indicates the relative coordinate value (change amount) of the item allocation position with respect to the character string start position.

The item name index table 2-3 has a character string cutout frame B in the item name print area A on the form image screen.
When the image data cut out from
This is an index table for converting this recognition character string into an item name. When searching the item name index table 2-3, the CPU 1 extracts a keyword included in the recognition character string, and if it is a keyword such as "money" or "quantity", a numeric type item, "date", If the keyword is “year / month / day” or the like, the type of the recognized character string is determined as in the case of the date / time type item, and the type-based index table is searched based on the determination result. That is, as shown in FIG. 2B, the item name index table 2-3 is divided into a numeric type table, a date / time type table, and other character string type tables, and a type-specific table corresponding to the type of the recognized character string. Search for. Here, various types of similar item names are stored in the type-specific table. For example, the item names including “representative” include “representative name”, “representative address 1”, and “representative address 2”. ...... is stored. The form data file 2-4 stores form data to be printed, which is printed and output according to the form set in the form form file 2-2, for each data print item. FIG. 3B shows this data structure. Is shown. Each print item is a generated item to which an input item to which key-input data is assigned or various index tables is searched, and data automatically generated by arithmetic processing is assigned, and a form corresponding to the input item or the generated item is assigned. The data is stored in the form data file 2-4. The character recognition dictionary 2-5 is a normal dictionary file that is referred to at the time of character recognition.

Next, the operation of the form processing apparatus will be described with reference to the flow charts shown in FIGS. Here, a program for realizing each function described in these flowcharts is stored in the storage medium 3 in the form of a readable program code.
1 sequentially executes operations according to the program code. FIGS. 5 and 6 are flowcharts showing the operation when newly registering a form. FIG. 9 and FIG. 10 are display states specifically showing processing steps when a form form is newly registered. The new registration processing will be specifically described below with reference to FIG. 9 and FIG. First, the CPU 1 reads a form image arbitrarily designated from the form image file 2-1 and outputs the read form image (steps A1 and A2). When the form is set on the form image display screen based on the form image, first, the mouse cursor is moved to a desired item name print area A to specify the area (step A3). FIG. 9A is a display state diagram in this case, in which the item name printing area A of the character string image “representative address” is selected and designated.

Then, the CPU 1 scans the designated item name print area A and analyzes a set of display ON dots to specify a character string range (rectangular area) existing in the item name print area A. This range is automatically determined as a character string cutout frame B, and this frame B is displayed as a candidate at a corresponding position in the item name print area A (step A4). FIG.
(B) is a display state diagram in this case, in which a character string cutout frame B is candidately displayed so as to surround the character string image "representative address". If the display position of the character string cutout frame B is correct, this determination is instructed (step A5). Then, the start position (upper left corner of the rectangle) of the character string cutout frame B determined as shown in FIG. 9B is detected, and its coordinate value is set as the character string reference position.
It is stored and held in the work memory in M4 (step A
6). Next, an item range frame D for specifying a data print item to be allocated in the data print region C corresponding to the item name print region A is displayed as a candidate according to the character string start position (step A7). Here, the item range frame D is a frame of a predetermined size, and the data print area C on the form image is displayed.
Does not always coincide with the size, but has a size corresponding to the size of the standard data print area C. A data print area C in which the Y coordinate values are aligned so that the upper left corner of the item range frame D matches the start position of the character string cutout frame B.
The item range frame D is displayed as a candidate at a position inside the box.

When the character string cutout frame B is determined,
Image data in the character string cutout frame B is cut out, and a character recognition dictionary 2-5 is extracted based on the image data.
, And performs a character recognition process of converting each character into a character code (step A8). As a result, when a recognized character string corresponding to the character string image is obtained, it is determined whether or not a predetermined keyword is included in the character string, and if the predetermined keyword is included, a type corresponding to the keyword is determined. Search the item name index table 2-3 (Step A)
9, A10). Here, if there are keywords such as “amount” and “quantity” in the recognition character string, numeric items, “date”,
If there is a keyword such as "year / month / day", it is determined to be a date / time type item, but if it does not contain a predetermined keyword, it is determined to be another character string item. Then, the type-specific item name index table 2-3 is searched based on the item type and the recognition character string. As a result, if there is an item name having the same name as the recognized character string (step A11 in FIG. 6), it is displayed as a candidate (step A12). Here, when the candidate is determined as the allocation item name, the determination is instructed (step A).
13). Now, as shown in FIG. 9C, when the character string image "representative address" is recognized as "representative name", the item name having the same name as the recognized character string is the item name index table 2-3. , The item name is displayed as a candidate. Since this item name is different from the image content, when the next candidate display is instructed (step A13), other item names similar to the recognized character string are displayed in the item name index table 2-3.
And a list is displayed in the candidate window (step A14). FIG. 10D shows a display state in this case, in which a corresponding candidate is selected and designated by a mouse cursor, and the determination is instructed to determine the selected candidate as an allocation item name (step A15). If there is no corresponding item name in this list display, a character string is directly input from the keyboard (step A16).

The item name thus determined or input is identified and displayed in the character string cutout frame B (step A17). That is, the area is identified and displayed by color display or blinking display to distinguish it from the unset area on the form image. In the next step A18, the position and size of the character string cutout frame B in the data print area C are finely adjusted by dragging the mouse.
The data print item is specified (see FIG. 10E). Then, based on the character string cutout frame B, the allocation position of the data print item (the upper left corner of the rectangular frame) and its horizontal and vertical sizes are detected (step A19), and the start position of the character string cutout frame B is determined. Based on the allocation positions of the data print items, their relative values (change amounts) are calculated (step A2).
0). Then, the assignment item name, the assignment position and size of the data print item, the character string start position, and the relative value are set and registered in the form file 2-2 as data for one record (step A21). FIG. 10F shows various parameters set in the form file 2-2. When the registration process for one item on the form image is completed in this way, it is checked in step A22 whether all items have been completed.
Until the process is completed, the process returns to step A3 of FIG.

Next, after the form is newly registered as described above, if the output format of the form is changed, a form change process is performed. 7 and 8
Is a flowchart showing this form change process. FIGS. 11A and 11B are display state diagrams for specifically explaining the change processing. FIG. 11A shows a form before change, and FIG. 11B shows a form after change. First, in a state where the changed form is read by the image scanner 8 and registered in the form image file 2-1, if the changed form image is designated, the CPU 1 reads it out and causes it to be displayed and output ( Step B1). Then, the item name printing area A on the display image is focused on from the top, the focused area is extracted (step B2), and the extracted item name printing area A is scanned to display the set of display on dots. The character string cutout frame B is automatically determined in accordance with the analysis, and candidates are displayed in the item name print area A (step B3). here,
When the determination of the character string cutout frame B is instructed, the start position of the character string cutout frame B is detected and stored (step B4), and the image data in the character string cutout frame B is cut out to obtain a character. Perform recognition (Step B)
5). Then, the allocation item name corresponding to the area of interest (the first area) is read from the form file 2-2 (step B6). The assigned item name is the registered item name before the change, and the assigned item name is compared with the changed item name after character recognition (step B7). As a result, when a match of the item name is detected, it is determined that the form information of the item has not been changed. However, when a mismatch of the item name is detected, the processing for automatically changing the form information of the item is performed. The process proceeds (steps B9 to B16).

Now, focusing on the third item name printing area A on the changed form image shown in FIG. 11B, if the recognized character string is “representative address,” Since the item name before the change corresponding to is "representative name" as shown in FIG. 11A, a mismatch between the two is detected. Then, a window in which the item names before and after the change are associated is displayed (step B9), and an instruction to change the assignment is waited for (step B10). This item name corresponding window is displayed on the changed form image as shown in FIG. 11 (B). After the operator confirms the displayed contents and instructs to change the allocation, the CPU 1 stores the form form file 2-2 in the form form file 2-2. Form change processing for rewriting the assigned item name and character string start position before the change to the item name and character string start position after the change (step B11) and after changing the character string cutout frame B on the display image Are identified and displayed (step B12). In this case, the identification display is also performed by color display or blinking display, thereby clearly indicating a changed portion.

Next, the character string starting position after the change,
This character string and the assigned position before the change corresponding to the corresponding item name having the same name are read out, and their relative values are calculated (steps B13 and B14). That is, FIG.
The starting position of the character string after the change is "representative address" as shown in
The form form file 2-2 is searched based on this item name (step B13), and the layout position of the data print item corresponding to the corresponding item name "representative address" having the same name is changed. It is read out as the previous allocation position, and based on the character string start position after the change and the allocation position before the change, their relative values are calculated (step B1).
4). Further, based on the changed item name, a relative value corresponding to the corresponding item name having the same name is searched from the form file 2-2 (step B15), and the calculated relative value is searched. The difference is calculated by comparing the relative value before the change (step B16). Then, based on this difference value, the post-change allocation position is calculated (step B17), and a form change process is performed to rewrite the pre-change allocation position in the form file 2-2 with the post-change allocation position (step B17). Step B18). FIG. 11 (C)
Indicates the assignment position before and after the change, and the assignment position after the change is one position higher than that before the change. Such form change processing returns to step B2 until the end of all items is detected in step B19, and is repeated for one item. FIGS. 12A and 12B show the contents of the form file 2-2 before and after the execution of the form change process, wherein FIG. 12A shows the state before the change and FIG. 12B shows the state after the change.

As described above, when a form is newly registered, image data is cut out from the item name print area A on the form image screen and characters are recognized, and an item name index is created based on the recognized character string. The table 2-3 is searched, and the search result is displayed as a candidate. When a desired candidate character string is selected from the search result, the candidate character string is stored in the form image information corresponding to the item name print area A on the form image. Is newly registered in the form file 2-2, setting of the item name can be easily performed. In other words, the contents displayed as candidates are narrowed down to only the item names that are the same or similar to the character strings recognized as characters, so the number of candidates is limited, and even if the printed typeface is recognized as characters. As a result, the recognition rate becomes higher, and the same item name is immediately displayed as a candidate. Therefore, when a desired item name is selected from the candidates, the selection becomes easy. In this case, it is possible to set an item name for each item while designating an arbitrary item name printing area A from among the item name printing areas A on the form image screen. Can be set, and the form can be set freely. In addition, when searching the item name index table 2-3, a keyword included in a character string that is recognized as a character is determined, and a type table corresponding to the keyword is preferentially searched according to the determination result. The search can be performed efficiently. Further, an item range frame D for specifying the data print item corresponding to the item name print area A is displayed for guidance, and the size and position of the item range frame D are finely adjusted to determine the data print item. Since the allocation position and size can be set as the form information, it is possible to easily set not only the item name but also the corresponding data print item.

When the form is changed and registered, the form form file 2-2 includes an item allocation position for each item defining the form output format, a character string in the item, and a character string. Since the relative value between the reference position of the column and the item allocation position is set as the form information, when the output format of the form is changed, the form is created based on the contents of the form file 2-2. Can be automatically corrected. That is, the image data is cut out from the item name print area A on the form image and characters are recognized. When a mismatch between the recognized character string and the character string before change is detected, the reference position of the character string after change is detected. Is calculated based on the reference position and the item allocation position before the change, and the changed item allocation position is calculated based on the change amount and the relative value before the change. The item allocation position before the change can be corrected based on the calculated value. In this case, the item name before the change can be corrected to the item name after the change. Furthermore, even if the item name after the change is incorrectly recognized, the item name before and after the change is displayed correspondingly,
The operator can confirm it, and as a result, when there is an instruction to change the assignment, the form is automatically corrected, so that it is possible to prevent erroneous correction due to misrecognized item names beforehand. It becomes possible.

It should be noted that the form information of each item corresponding to the header area and the total area may be set on the form image, not limited to each item in the detailed area. Although the item name print area A on the form image is designated by the mouse cursor, the designation is not limited to the mouse but may be designated by an input means such as a key or an input pen.

[0019]

According to the first aspect of the present invention, when setting a form based on a form image, character strings on the form image are recognized by characters, so that a character string such as an item name can be easily formed. Can be set. According to the second invention, after designing the form based on the form image, even if the output format of the form is changed, the analysis result obtained by analyzing the changed form image and the change The form can be automatically corrected based on the previous form information.
