[0002]

2. Description of the Related Art Recently, in a word processor, a charge-coupled device (CCD) is mounted on a carriage portion on which a print head is mounted.
Device), an image scanner head is configured to read an original document placed on a paper feed unit as an image, recognize the document content, and handle the recognized document content as an edited document. Devices provided with such an image scanner function and a document recognition function have become widespread.

As a document read by an image scanner mounted on a word processor as described above, for example, a document in a table format surrounded by ruled lines printed on paper of a predetermined size (A4 size or the like) is read, and the contents are read. Recognize and create the contents as a document. Also,
If you read a tabular document that is surrounded by ruled lines created by handwriting, the handwritten image will be read as it is, so there will be large fluctuations in the row column pitch in the table. Was not performed.

[0004]

However, in a word processor having an image scanner function and a document recognition function in which an image scanner head is mounted on a carriage portion on which such a conventional print head is mounted, handwriting is performed by handwriting. When a table-format document that is surrounded by the ruled lines is read, the handwritten image is read as it is, so the row-column pitch in the table still has large fluctuations. And so on, the appropriate number of lines cannot be assigned to the recognized table, and there is a problem that it is difficult to shift to document creation.

An object of the present invention is to read a table created by handwriting with an image scanner and recognize the same, when creating a document, by recognizing the number of lines in the table by the number of characters between ruled lines in the line and column direction. The number of lines and the number of digits are determined in accordance with the maximum number of characters, thereby facilitating creation of a table document.

[0006]

According to the first aspect of the present invention,
Recognizing means for recognizing a handwritten table ruled line and a character string in the table ruled line, determining means for determining the maximum number of line digits of the character string for each table block of the recognized table ruled line, and inputting an output size An input means, a line-column pitch for each table block is obtained based on the determined number of line-columns and the input output size, and a new table for each table block is obtained based on the maximum number of line-columns and the line-column pitch of the character. Control means for obtaining a ruled line,
It is characterized in that the recognized table rule line is replaced with the determined table rule line.

According to the ruled line processing apparatus of the first aspect of the present invention, when a handwritten table ruled line and a character string in the table ruled line are recognized by the recognizing means, a character is set for each table block of the recognized table ruled line. The maximum number of rows and columns of the column is determined by the determination unit, and the control unit obtains the row and column pitch of each table block based on the determined number of rows and the output size input by the input unit. A table ruled line for each new table block is determined based on the number of line digits and the line column pitch, and the determined table ruled line is replaced with the recognized table ruled line.

[0008] Therefore, when a hand-drawn table document with an ambiguous digit pitch is read, the required number of line digits can be recognized / shaped as a table ruled line and easily used in a document.

The example shown in FIG. 8A shows a case of a table original in which a handwritten table is written on A4 size paper, and a range of an inner frame 280 mm in the figure in the width of 297 mm of the A4 paper is read. It is assumed that a table image is read by the image scanner 5 as the range. In addition,
In FIG. 8A, “the maximum number of output digits is 30” and “the number of table digits is 1”.
The “five digits” will be described later in the processing.

Then, a ruled line image is extracted from the read table image, and the coordinates of the ruled line are obtained from the ruled line image (step S3). For example, as shown in FIG. 9, the coordinates of each ruled line block surrounded by ruled lines are obtained as the coordinates in the digit direction as, and the coordinates in the row direction as (A), (A) and (C). The acquired digit coordinates and row coordinates are stored in the digit number memory 4b shown in FIGS. 3 (a) and 3 (b).

Step S52). The set of the digit coordinates and the set of the row number counter value 1 indicate that the first line in the ruled line block indicated by the digit coordinates in FIG. 9 is specified.

Then, the number of character digits in the column direction of the designated first line is identified (step S53), and it is determined whether or not the identified number of character digits is the maximum number of character digits in the ruled line block of digit coordinates. (Step S54). If it is the maximum number of character digits, the value of the digit coordinate set in the inter-digit counter 4f and the value of the number of character digits are stored in the digit number memory 4b in association with each other (step S55). If the number of character digits is not the maximum, or after the processing of step S55 is completed, it is confirmed whether or not the identification processing of the number of character digits has been completed for all lines in the ruled line block at the designated digit coordinates (step S56). ). If the character digit number identification processing has not been completed for all lines, the line spacing counter 4g is counted up (+

It is determined whether or not the number of character digits of the line is the maximum number of character digits in the ruled line block of the digit coordinates (step S54).

As described above, by repeatedly executing the processing from step S53 to step S57, the line having the maximum number of character digits in the ruled line block of the digit coordinates is recognized.
The relationship between the inter-digit coordinates and the maximum number of character digits, which is the recognition result, is stored in the digit number memory 4b.

When the process of recognizing the number of character digits of all lines in the ruled line block of the first designated digit coordinate is completed, it is confirmed whether or not the process of recognizing the number of character digits of the inter-digit block is completed. (Step S58). If the recognition processing of the number of character digits in all the inter-digit blocks has not been completed, the inter-digit counter 4f is counted up (+1), that is, the digit coordinates are changed to empty (step S5).
9) Returning to step S52, "1" is set again in the row number counter 4j. The set of the digit coordinates and the set of the row number counter value 1 indicate that the first line in the ruled line block indicated by the digit coordinates in FIG. 9 is specified.

Then, the number of character digits in the column direction of the designated first line is identified (step S53), and it is determined whether or not the identified number of character digits is the maximum number of character digits in the ruled line block of digit coordinates. (Step S54). If it is the maximum number of character digits, the value of the digit coordinate set in the inter-digit counter 4f and the value of the number of character digits are stored in the digit number memory 4b in association with each other (step S55). If the number of character digits is not the maximum, or after the processing of step S55 is completed, it is confirmed whether or not the identification processing of the number of character digits has been completed for all lines in the ruled line block at the designated digit coordinates (step S56). ). If the character digit number identification processing has not been completed for all lines, the line spacing counter 4g is counted up (+
1) (Step S57), and return to Step S53 to recognize the number of character digits in the digit direction of the next one line. It is determined whether or not the number of character digits of the line is the maximum number of character digits in the ruled line block of the digit coordinates (step S54).

As described above, by repeatedly executing the processing from step S53 to step S57, the line having the maximum number of character digits in the ruled line block of the digit coordinates is recognized.
The relationship between the inter-digit coordinates and the maximum number of character digits, which is the recognition result, is stored in the digit number memory 4b.

As described above, by repeatedly executing the processing from step S52 to step S58, FIG.
And the relationship between the inter-digit coordinate and the maximum number of character digits as a result of the recognition is stored in the digit number memory 4b.
The process for identifying the number of digits in the block is completed.

Next, step S6 of the main flow of FIG.
Then, the number of lines in the block for identifying the number of character lines in the recognized ruled line block is executed. The process of recognizing the number of lines in a block will be described with reference to the flowchart shown in FIG.

In FIG. 7, first, the first row coordinates (A) of the row coordinates acquired by the line spacing counter 4g in the RAM 4 are shown.
Is set (step S61), and "1" is set to the digit number counter 4i in the RAM 4 (step S62). By setting the row coordinates (A) and the digit number counter value 1, the first digit in the ruled line block indicated by the row coordinates (A) in FIG. 9 is designated.

Then, the number of character lines in the line direction of the designated first digit is identified (step S63), and whether the identified number of character lines is the maximum number of character lines in the ruled line block having the line coordinates (A) is determined. Is determined (step S64). If it is the maximum number of character lines, the value of the line coordinates (a) set in the line spacing counter 4g and the value of the number of character lines are associated with each other,
c (step S65). If it is not the maximum number of character lines, or after ending the processing of step S65, it is confirmed whether or not the identification processing of the number of character lines has been completed for all the digits in the ruled line block at the designated line coordinates (A). (Step S66). If the character line number identification process has not been completed for all digits, the digit counter 4f is counted up (+1) (step S67), and step S63 is performed.
To recognize the number of character lines in the next one-digit line direction. It is determined whether or not the number of character lines of the digit is the maximum number of character lines in the ruled line block having the line coordinates (A) (step S64).

As described above, by repeatedly executing the processing from step S63 to step S67, the digits of the maximum number of character lines in the ruled line block at the line coordinates (A) are recognized, and the line spacing as the recognition result is obtained. The relationship between the coordinates and the maximum number of character lines is stored in the line number memory 4c.

Then, the first designated row coordinate (A)
When the process of recognizing the number of character lines of all digits in the ruled line block is completed, it is checked whether the process of recognizing the number of character lines in the inter-line block has been completed (step S68). If the process of recognizing the number of character lines in all the interline blocks has not been completed, the line interval counter 4g is counted up (+1), and
That is, the line coordinates are changed and designated from (A) to (A) (step S69), and the process returns to step S62 to set "1" to the digit number counter 4f again. These row coordinates (b)
And the setting of the digit number counter value 1, the first digit in the ruled line block indicated by the row coordinate (a) in FIG. 9 is designated.

Then, the number of character lines in the line direction of the designated first digit is identified (step S63), and whether or not the identified number of character lines is the maximum number of character lines in the ruled line block at the line coordinates (a) is determined. Is determined (step S64). If it is the maximum number of character lines, the line number memory 4 associates the line coordinate value (a) set in the line spacing counter 4g with the character line number value.
c (step S65). If it is not the maximum number of character lines, or after ending the processing of step S65, it is confirmed whether or not the identification processing of the number of character lines has been completed for all the digits in the ruled line block at the specified line coordinates (A). (Step S66). If the identification processing of the number of character lines has not been completed for all digits, the digit counter 4f is counted up (+1) (step S67), and step S63 is performed.
And the number of character lines in the column direction of the next one line is recognized. It is determined whether or not the number of character lines of the digit is the maximum number of character lines in the ruled line block at the line coordinates (a) (step S64).

As described above, by repeatedly executing the processing from step S63 to step S67, the digit of the maximum number of character lines in the ruled line block of the line coordinates (A) is recognized, and the line spacing as the recognition result is obtained. The relationship between the coordinates and the maximum number of character lines is stored in the line number memory 4c.

As described above, by repeatedly executing the processing from step S62 to step S68, FIG.
The maximum number of character lines in each ruled line block at the line coordinates (c) shown in (1) is recognized, and the relationship between the line coordinates and the maximum number of character lines as the recognition result is stored in the line number memory 4c. The process of identifying the number of lines in a block is completed.

Next, step S7 of the main flow of FIG.
Returning to FIG. 8, the sheet size of the front document detected by the sheet size detection unit 6, the sheet size “A4” in the example of FIG.
Is detected, and the reading range 28 of the paper size A4 in FIG.
0 mm is detected. Then, the detected paper size A
Then, the ratio of the displayed table image to the reading range 280 mm of No. 4 is calculated (step S8). For example, reading range 2
Assuming that the size of the front image is 140 mm with respect to 80 mm, the ratio is “2: 1”.

Next, from this ratio "2: 1", the number of digits of the entire sheet is calculated from the number of digits of the table portion (step S9).
That is, each digit coordinate block stored in the digit number memory 4b by the digit number identification process in the block in the step S5.
Is the total number of characters in the
Assuming that the maximum number of digits in the table is “15 digits” as shown in FIG. 8A, the maximum number of digits of the paper output is “15 digits” × 2.
Becomes "30 digits".

Next, the number of digits in all the lines in the document written in each ruled line block designated by the column coordinates and line coordinates (A) to (C) in the displayed handwritten table image is identified ( In step S10, the line-to-line pitch between characters is determined from the paper size (reading range 280 mm) detected in step S7, the number of handwritten character points, and the total number of character line digits recognized in step S10 (step S11). FIG.
In the example of the table original shown in (a), the table size is “140 m”.
Since the maximum number of digits in the table is “15” for “m”, the character digit pitch between characters is “140 mm ÷ 15 digits = 9.3 mm”.

With reference to the point table 4h shown in FIG. 4 from the obtained character digit pitch "9.3", an optimum character point "22" for the digit pitch is obtained (step S).
12). The line digit pitch of the character obtained in this manner, the character coordinates in the displayed handwritten table image identified in step S10 and the characters in each ruled line block designated by the line coordinates (A) to (C) New ruled line coordinates (between digits and between lines) are obtained from the number of line digits (step S13). That is, the ruled line coordinates (between digits and lines) for shaping the ruled line coordinates of the displayed handwritten table image are determined by the number of character lines in each ruled line block identified in step S10, and step S11.
As shown in FIG. 10, based on the character line digit pitch obtained in step S12 and the character points acquired in step S12, the outer frame ruled line and digit space, line ruled line coordinates (X, Y), (X
1, Y), ~ (X3, Y), (X, Y1), ~ (X, Y
2) Ask for.

Then, instead of the table image data read from the currently displayed table document, only the ruled lines of the table based on the newly obtained digit and row coordinates are displayed as shown in FIG. 8B (step). S14). That is, characters written in the ruled line block by handwriting are deleted, and only the ruled line frame is displayed on the display device 7. Next, the processing mode is automatically switched to the document / table editing mode (step S15),
The input of the document data in the newly formatted table is enabled, and only the newly displayed table data is stored in the document memory 4d in the RAM 4 (step S16).

In the editing mode, when input of document data or an instruction to edit the table is input into the displayed table,
The editing process is executed according to each input instruction (step S
17), and confirms the end instruction of the editing process (step S1)
8) The edited data is given a name and stored in the document memory 4d (step S19), and the main-table original reading process ends.

As described above, in the word processor 1 of the present embodiment, the CPU 2 prints the table written by hand on the document sheet to be read in the front document reading process.
Is read by an image scanner 5 mounted on a carriage having a print head, and the coordinates of the ruled lines of the read table image are obtained / identified, and then written in each block surrounded by the line and column ruled lines of the table image. The maximum number of digits and the maximum number of lines of the table are recognized based on the maximum number of digits and the maximum number of lines of the character. Then, the CPU 2 calculates the ratio of the recognized maximum number of digits and the maximum number of lines to the detected paper size, calculates the number of character points and the line column pitch in the table block based on the ratio, and calculates the calculated number of character points. Since the coordinates of the ruled line of the new table are determined from the row and column pitches, only the ruled line of the table is displayed on the display device 7, and the process shifts to an editing process in which a document can be edited in the table. The operability can be improved by omitting the operation burden for shifting to the processing.

Therefore, in a word processor 1 equipped with an image scanner, when a handwritten table document having an unclear line-digit pitch is read, the required number of line digits is recognized / shaped as a ruled line and used in a document. Can be done easily. Further, in a word processor equipped with an image scanner, a function of reading a handwritten table original and an image shaping function can be enhanced to facilitate creation of a table document, and to facilitate reading and using a handwritten form. Can be. As a result, the table editing function of the word processor can be enhanced, and the usability can be improved.

In the front document reading process shown in FIG. 5, a case has been described in which all handwritten documents are deleted and only the ruled lines of the table are newly displayed to facilitate the transition to the editing process. By adding the flowchart shown in FIG. 11 to the portion indicated by "A" in FIG. 5, it becomes possible to store a handwritten table and handwritten characters.

That is, in the handwritten character recognition process shown in FIG. 11, handwritten characters in the displayed table image are recognized.
The recognized characters are converted into character codes, and the recognized character codes are stored in association with the corresponding ruled line coordinates in the table (step S101). Next, when each of the converted character codes is displayed in the table, it is displayed in the table based on the arrangement position of the character code, the character point, and the line column pitch. First, the ruled line is displayed based on the character code, and the character code is displayed at the corresponding arrangement position (step S102).

By adding the above two steps, the handwritten characters in the table can be recognized / displayed in the formatted table, and the trouble of inputting the characters after the process shifts to the editing process can be omitted. Can be.

In the above-described embodiment, the case where the present invention is applied to the word processor 1 has been described. However, the present invention can be applied to a system configuration in which an image scanner is separately provided.

In the above-described front document reading process, the size of the front document to be read has been described as "A4". However, it is needless to say that a front document of another paper size can be processed, and that the size of the document to be read is limited. If so, it is limited only to the readable range of the image scanner.

Can be easily used on top.

According to the ruled line processing apparatus of the present invention, when replacing the recognized table ruled line with the determined table ruled line, the image in the table ruled line is erased. The transition to the document input process can be facilitated.

According to the ruled line processing apparatus of the present invention, after erasing the image in the table ruled line, the process shifts to an editing process in which characters and the like can be entered in the table ruled line. The operability can be improved by omitting the operation burden for shifting to the processing.
