[0004]

In the conventional character recognition,
If there is no correct candidate among the recognition candidates, you cannot enter the desired character even if there are similar characters with the same radical in the candidate, so you have to rewrite the same character, which is a waste of effort. It was troublesome and troublesome.

An object of the present invention is to make it possible to easily input a desired character by using the character of the recognition candidate without rewriting the character even if the character itself to be input is not among the recognition candidates. .

[0006]

The present invention provides a tablet as a handwriting input means, a recognition dictionary having a combination of writing data of characters and a character code, and handwritten characters input from the tablet by referring to the recognition dictionary. A handwritten character recognition means for converting writing data of the above into a character code, a character configuration dictionary holding the character code and the configuration of the character,
This is achieved by providing partial correction means for correcting a specified portion of a character with reference to the character composition dictionary.

[0007]

In the handwritten character input device, when the character to be input is not in the recognition candidates, one character is specified from the recognition candidates, and one or more parts of the character are corrected to obtain the desired character. Can be entered.

According to the present invention, even if the correct candidate itself is not among the recognition candidates, it is possible to easily input the correct character using the characters of the recognition candidate. This eliminates the need to rewrite characters and reduces the time required to enter characters.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the character input device of the present invention will be described below with reference to the drawings.

FIG. 2 is an external view of this embodiment. The apparatus of this embodiment is roughly divided into a main body 201 and a stylus 202.
Composed of. The main body 201 includes a display-integrated handwriting input tablet 203.

FIG. 1 is a basic configuration diagram of this embodiment. The handwriting input means 101 is realized by handwriting with the stylus 202 on the display-integrated handwriting input tablet 203. The character recognition unit 102 uses the character recognition dictionary 103 to convert the information input by the handwriting input unit 101 into a character code. The partial correction unit 104 refers to the character structure dictionary 105, corrects one or a plurality of parts forming a character, and outputs another character. The display unit 106 displays the handwriting of the input handwritten character, the candidate character for character recognition, the character output by the partial correction unit, and the like. In this embodiment, the display is realized on the display-integrated tablet 203.

FIG. 3 shows the input screen structure of this embodiment. The character information display area 301 is an area for displaying an input character or character string. Handwritten character input display frame 302
Is a frame for inputting handwriting with the stylus 202 and displaying inking data of handwritten characters and candidates for character recognition. The software button 303 executes various functions when instructed by the stylus 202.

Character recognition information is registered in the recognition dictionary 103. In this embodiment, at least "total" and "correction" are registered.
Information such as "death", "deal", and "town" are registered.

FIG. 4 shows an example of dictionary contents of the character structure dictionary 105. Character code 4 of a certain character in one record
01, one or more character component codes 402 indicating the part forming the character, and position information 403 for each character component are stored. In addition, in this example of contents, an image is used instead of a character code or a character component code for easy understanding.

FIG. 5 shows an example of the input method of this embodiment. The user tried to input the character “total” and handwritten the character like 501 to perform character recognition, but the character “total” was not in the recognition candidates on the candidate display screen like 502. At this time, the partial correction means 104 refers to the character structure dictionary 105, and based on the position information 403, displays the first candidate character "compression" by dividing it into a plurality of parts "word" and "ding". To do. This divided part is called a character part. At this time, if the display attributes such as shade, inversion, outline, bold, typeface or display color are changed for each divided portion, it is possible to determine at a glance how the division is made. Here, when the user presses the portion of the character component “Ding” to be corrected, which is the first candidate for character recognition, with the stylus 202, the partial correction means 104 refers to the character structure dictionary 105 and refers to the character component “in addition to“ correction ”. The characters “total”, “sanction”, and “deal”, which are the characters replacing “Ding”, are displayed as candidates 503. When the user presses the “total” with the stylus 202 as in 504, the “total” becomes the first candidate as in 505. As described above, in this input example, even if the character desired by the user is not in the recognition candidates, the character can be easily input without rewriting the character.

FIG. 6 shows an example of another input method of this embodiment. When the user tries to enter the character "total",
Character recognition was performed by handwriting characters such as 01.
In the candidate display screen such as 02, the character "total" was not in the candidates. At this time, the partial correction means 104 refers to the character structure dictionary 105 to display the first candidates of the character parts "Koto" and "Ding" at the same time as the candidate characters. At this time, display attributes such as the display color are changed to the text part “Word”.
And "Ding" and other candidate characters are displayed differently, and the parts corresponding to the first candidate "correction" character parts "Koto" and "Ding" have the same display attributes as the respective character parts based on the position information 403. By displaying with, it is possible to determine at a glance which part of the character each candidate corresponds to. In this example of the input method, only the character components forming the first candidate character are displayed as candidates, but character components of other candidate characters may be displayed together. Here, when the user presses a character other than the first candidate that is not a character part with the stylus 202, that character becomes the first candidate and the character part of that character is displayed in the same manner. Further, here, when the user presses the character part “word” portion with the stylus 202 as in 603, the partial correction unit 104 refers to the character configuration dictionary 105 and refers to a character having a “word” portion as in 604. "Correction""total""correction"
Display "deal" as a candidate. When the user presses the “total” from among these with the stylus 202, the “total” becomes the first candidate as in 605. As described above, also in this input example, even if the character desired to be input by the user is not in the recognition candidates, the character can be easily input without rewriting the character. According to this input method example, the handwritten character input device of the present invention can easily perform radical input.

It is also preferable that a plurality of character parts can be designated so that characters can be input. For example, FIG. 8 shows another example of the input method of this embodiment.
When the user tries to enter the word "drug", 801
I did handwriting and recognized the character like
In the candidate display screen, there was no word "Taku" in the candidates. Here, after the user presses the component selection button, which is one of the software buttons 303, with the stylus 202, the user presses the “word” part of the candidate character “total” with the stylus 202, as in 803, and the candidate as in 804. Character "village"
When the user presses the "dimension" part of the stylus 202 with the stylus 202 and the enter button stylus 202, which is one of the software buttons 303, the partial correction unit 104 refers to the character structure dictionary 105 and displays the character parts as indicated by 805. "Word"
And the character "Tou" with the character part "Dimension" is displayed as the first candidate. As described above, according to this input example, even if the character to be input is not the character of the recognition candidate, if the character component forming the character is the character of the recognition candidate, the character can be easily input.

FIG. 7 is a processing flow of this embodiment. Starting at step 701, the handwritten character recognition means 102 refers to the recognition dictionary 103 at step 702 to perform recognition processing of the character handwritten by the user, and displays candidate characters at step 703. Then, in step 704, the type of the next input is determined. If it is determined in step 704 that the input is candidate selection, candidate selection processing is performed in step 705, and the candidate selected by the user is set as the first candidate, and step 70
Return to 3. If it is determined in step 704 that the input is partial correction, the partial correction means 104 refers to the character structure dictionary 105 to create and display correction candidates in step 706, and performs partial correction processing according to the user's selection.
