[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document editing apparatus, and more particularly, to a document editing apparatus that operates by recognizing handwritten characters and proof symbols online.

[0002]

2. Description of the Related Art Conventionally, in a document editing apparatus of this type, as shown in FIG. 7, a handwritten character figure and a proof figure input from a coordinate input section 11 are converted into an internal code by a recognition section 12, and the internal code is converted into an internal code. The code is interpreted by the document editing unit 14 to operate the document data, and the editing result of this document data is displayed on the display unit 14.

That is, when the operator inputs a character or a calibration symbol as a handwritten figure using the coordinate input section 11 such as a tablet or a light pen, the handwritten figure is output from the coordinate input section 11 to the recognition section 12.

The recognition unit 12 recognizes the handwritten figure from the coordinate input unit 11 as a character or a proof symbol by a method such as pattern matching, converts it into an internal code corresponding to the character or the proof symbol, and outputs it to the document editing unit 13. To do. Here, the internal code representing the character graphic and the calibration symbol graphic consists of a character code and a calibration code.

The document editing unit 13 evaluates the validity of the character code and the proofreading code input from the recognition unit 12, and updates the document data stored in advance when it becomes executable as an editing function.

The document editing unit 13 stores the updated document data and outputs the currently stored document data to the display unit 14. As a result, the update result of the document data is displayed on the display unit 14, so that the operator can visually check it. Regarding the above technique, Japanese Patent Laid-Open No. 61-
It is disclosed in Japanese Patent No. 107468.

In the recognition unit 12, there is a system in which the recognition operation is started after an operator's instruction for each input unit of one character or calibration symbol. In the case of this method, the recognition unit 12
Categorizes the graphic data into characters or calibration symbols according to the operator's instruction, and converts the graphic data into an internal code based on the classification result.

Each time a component such as a point or a line is input, the suitability of the graphic data as a character or a calibration symbol is verified, and the graphic data determined to have the compatibility by the verification is recognized. The method of performing may be used. In the case of this method, when the graphic data is input, the recognition unit 12 classifies whether it is a character or a calibration symbol.

In the case of Japanese consisting of hiragana, katakana, kanji, etc., it is necessary to classify a specific character from among thousands of character candidates. One particular symbol must be classified from dozens of symbol candidates such as lines and area designations.

Further, when the graphic data is a character, the sizes and arrangements thereof are almost the same, but in the case of a calibration symbol, the size and the shape are different depending on the operation target, and various shapes are obtained.

[0011]

In the above-mentioned conventional document editing apparatus, since inputted graphic data is classified from a large number of characters and proofreading symbols as various graphics, it is difficult to recognize correctly. Therefore, high-speed, complicated and expensive hardware is required to correctly perform recognition processing.

Further, in the case of the method in which the operator gives an instruction to start the recognition for each input unit, there is a problem that a quick editing process is hindered and the operation time increases.

Therefore, an object of the present invention is to solve the above-mentioned problems, to enable quick editing processing without requiring high-speed, complicated and expensive hardware, and to shorten the operation time of a document editing apparatus. To provide.

When the area code b is input from the area recognizing section 2, the operation recognizing section 3 selects the operation code candidates "open (line spacing)", "superscript", and "subscript" corresponding to the "line spacing 1".
Is read from the operation recognition table 3a.

After that, the operation recognition unit 3 selects a specific operation code corresponding to the coordinate data a from the coordinate input unit 1 from among the operation code candidates “open (line spacing)”, “superscript”, and “subscript”. Select and output. In this case, since the line segment is drawn on the "BCD", the operation recognition unit 3 selects "superscript" as the specific operation code and determines that the calibration character input is not necessary. Therefore, the area code b And this specific operation code is output to the document editing unit 5 as the area operation code d.

Since the operation code of the document editing unit 5 is "superscript", "BCD" in which a line segment is drawn above the character string "ABCDE" is raised (see FIG. 6), and the editing process is terminated. . The character string “A ^BCD E” edited by the document editing unit 5 and having “BCD” on the top is output to the display unit 6 as an edited result f.

The operator uses the coordinate input section 1 to input the character string “A
When the coordinate data a with a line segment is input under “BCD” in “BCDE”, the area recognition unit 2 causes the coordinate data a to be input.
From this, it is classified as "line spacing 1", and this "line spacing 1" and the information on the input position are output to the operation recognition unit 3 as the area code b.

When the area code b is input from the area recognizing section 2, the operation recognizing section 3 selects the operation code candidates "open (between)", "superscript" and "subscript" corresponding to the "line spacing 1".
Is read from the operation recognition table 3a.

After that, the operation recognition unit 3 selects a specific operation code corresponding to the coordinate data a from the coordinate input unit 1 from the operation code candidates “open (line spacing)”, “superscript”, and “subscript”. Select and output. In this case, since the line segment is drawn below "BCD", the operation recognition unit 3 selects "subscript" as the specific operation code and determines that the calibration character input is not necessary. Therefore, the area code b And this specific operation code is output to the document editing unit 5 as the area operation code d.

Since the operation code of the document editing unit 5 is "subscript", "BCD" with a line segment drawn below in the character string "ABCDE" is lowered (see FIG. 6) and the editing process is terminated. . The character string "A _BCD E" edited by the document editing unit 5 and having "BCD" turned down is output to the display unit 6 as an edited result f.

The operator uses the coordinate input section 1 to input the character string “A
"Line spacing" of "BCDE", "Line spacing", "FGGIJ"
When the coordinate data a in which a closed curve is drawn is input to the area recognition unit 2, the area recognition unit 2 classifies the coordinate data a into "line spacing 2", and the "line spacing 2" and the information regarding the input position are handled as the area code b by the operation recognition unit 3 Output to.

When the area code b is input from the area recognizing section 2, the operation recognizing section 3 reads out an operation code candidate "catch (line spacing)" corresponding to the "line spacing 2" from the operation recognizing table 3a.

After that, the operation recognition unit 3 outputs the operation code candidate “catch (line spacing)” to the coordinate data a from the coordinate input unit 1.
And output as a specific operation code corresponding to.
In this case, the operation recognition unit 3 determines that the proofreading character input is unnecessary, and therefore outputs the area code b and this specific operation code to the document editing unit 5 as the area operation code d.

Since the operation code of the document editing section 5 is "catch (line spacing)", the character string "ABCDE" with a closed curve is drawn.
The "line interval" between the character string "FGHIJ" and the character string "FGHIJ" is removed by the interval included in the operation designation (see FIG. 6), and the editing process ends. The text string "AB was edited by the document editing unit 5.
The character strings "ABCDE" and "FGHIJ" from which the "line spacing" between the CDE "and the character string" FGHIJ "has been removed are output to the display unit 6 as the edited result f.

The operator uses the coordinate input unit 1 to draw a closed curve in the "margin" of the document data, and the character "12" is drawn in the closed curve.
When the coordinate data a in which “3” is handwritten is input, the area recognition unit 2 classifies the coordinate data a into a “margin”, and the “margin” and information about the input position are input to the operation recognition unit 3 as an area code b. Output.

When the area code b is input from the area recognition section 2, the operation recognition section 3 reads out the operation code candidate "character input" corresponding to the "margin" from the operation recognition table 3a.

After that, the operation recognition section 3 selects and outputs the operation code candidate “character input” as a specific operation code corresponding to the coordinate data a from the coordinate input section 1. In this case, the operation recognition unit 3 determines that the calibration character input is necessary, and therefore outputs the area code b and this specific operation code to the character recognition unit 4 as the area operation code c.

When the area operation code c is input from the operation recognition section 3, the character recognition section 4 takes in the coordinate data a from the coordinate input section 1 into the inside, and performs pattern recognition with the taken coordinate data a as a character figure. Go and convert to character code. In this case, the handwritten character “123” is converted into a character code by pattern recognition, and the area operation character code e including the area operation code c and the character code of the handwritten character “123” is output to the document editing unit 5.

In the document editing section 5, the operation code is "character input".
Therefore, the character code of the handwritten character "123" is put in this "margin" (see FIG. 6), and the editing process is terminated. The document data edited by the document editing unit 5 and having the character code of the handwritten character “123” in the “margin” is output to the display unit 6 as the edited result f.

As described above, the document editing section 5 operates by performing an operation according to a simple rule.

As described above, after the area recognition unit 2 detects the area graphic based on the graphic data from the coordinate input unit 1, the operation recognition unit 3 limits the operation code candidates according to the area classification of the area recognition unit 2. The operation recognition section 3 detects an operation figure from the figure data from the coordinate input section 1, the character recognition section 4 performs character recognition as necessary, and based on the area figure, the operation figure, and the result of the character recognition. By updating the document data in the document editing unit 5, classification of calibration symbols composed of area figures and operation figures and character recognition are facilitated, and high-speed, complicated and expensive hardware is unnecessary. Therefore, a low-priced document editing device can be provided.

Further, if the operator learns rules that are easy to input, the figure recognition rate is high, so that quick editing work is possible and the operation time can be shortened.
