Abstract

PURPOSE:To efficiently perform the input of a KANJI (Chinese character) in which a large number of homonyms exist by designating an unrequired part in the conversion result of hand-written KANA (Japanese syllabary)/KANJI conversion, and setting a part other than a designated part as an effective conversion result. CONSTITUTION:A hand-written KANA character is inputted from a character input means 100, and a KANA character is recognized by a recognition means 200. The KANA character is converted to the KANJI by a KANA/KANJI conversion means 300. The conversion result is displayed on a display means 400. At this time, the KANJI is settled by indicating the unrequired part in the conversion result with a pen, etc., and setting a remaining part from which the said unrequired part is eliminated by an unrequired character erasing means 500 as valid.

Description

[Detailed Description of the Invention] [Summary] Regarding a handwritten kana-kanji conversion method that recognizes handwritten kana characters and converts them into kanji, an input operation that deletes unnecessary parts due to idiom input when inputting kanji with many homonyms is provided. The purpose is to simplify and improve the efficiency of text input, and when displaying the conversion result that has been converted into kana-kanji by recognizing handwritten kana characters, by specifying the unnecessary part of the conversion result, the remaining part will be displayed excluding the specified part. is configured to be determined as a valid conversion result.

[Industrial Application Field] The present invention relates to a handwritten kana-kanji conversion method for recognizing handwritten kana characters and converting them into kanji.

For handwritten character input devices that convert handwritten kana characters into kanji after recognizing them, if there are many homonyms for the kanji to be input, the system first outputs an idiom that includes the kanji to be input, and then converts it into kanji. Unnecessary characters may be deleted.

In such a case, you will need to convert from input mode to edit mode and delete unnecessary characters, but in order to increase the efficiency of text input, it is desirable to make the deletion of unnecessary characters as simple as possible. .

[Conventional technology] FIG. 5 is a diagram showing the configuration of a conventional system.

In Fig. 5, 1 is a handwritten character input section using a tablet or the like to write and input handwritten kana characters, 2 is a conversion instruction section that instructs ephemeral kanji conversion, 3 is a recognition section that recognizes input kana characters, and 4 is a recognition section that recognizes input kana characters. A recognition result holding unit that holds one or more recognized recognition candidates; 5 is a recognition next candidate instruction unit that instructs selection of the next candidate from among the plurality of recognition results; 6 is a recognized Kana character in the recognition result holding unit 4; 7 is a conversion result holding unit that holds one or more candidates converted into ephemeral kanji, and 8 is a conversion next candidate instruction that instructs to select the next conversion candidate from among multiple conversion results. Part 9 is a CRT that displays the conversion results of recognized kana characters or kana-kanji characters.
This is a display section such as 10, and a confirmation instruction section that issues a confirmation instruction when a desired character is displayed in selecting the next candidate of the 10 kana-kanji conversion results.

In such a conventional handwritten character input device, when a kanji to be input into the handwritten character input section 1 is written in kana with the conversion instruction section 2 instructing kana-kanji conversion,
Kana characters are recognized by the recognition unit 3, and one or more recognition results are stored in the recognition result storage unit 4. At this time, since kana-kanji conversion is instructed, the first candidate recognition result is given to the kana-kanji conversion unit 6, one or more conversion results are held in the conversion result holding unit 7, and the first candidate recognition result is held in the conversion result holding unit 7. 1
Candidates are displayed on the display section 9. At this time, if the displayed kanji is different from the kanji to be inputted, the user selects and displays the next conversion candidate using the conversion next candidate selection instruction unit 8, and then selects and displays the next conversion candidate until the desired kanji is displayed. Repeat the selection instructions.

When the kanji to be inputted has finally been selected, the confirmation instruction section 10 issues a confirmation instruction to complete the series of kanji input and move on to inputting the next character.

On the other hand, when inputting kanji using Kana-Kanji conversion, if there are many homophones for the kanji you are trying to input, input the idioms that include the kanji you are trying to input in Kana, output them using Kana-Kanji conversion, and then input unnecessary parts. Delete.

To delete unnecessary parts of the conversion result, it is necessary to change the previous input mode to an edit mode for character deletion, and after deletion, it is necessary to return to the input mode again.

[Problems to be Solved by the Invention] However, in such a conventional handwritten kana-kanji conversion method, when deleting unnecessary parts of kanji input with many homonyms as an idiom input, it is difficult to switch from input mode to edit mode. This requires a changing operation, which poses a problem in that efficient text input is hindered.

The present invention has been made in view of such conventional problems, and provides a handwritten kana-kanji conversion method that increases the efficiency of text input by simplifying the operation of erasing unnecessary parts by inputting Juku8B etc. The purpose is to

[Means to solve the problem] FIG. 1 is a diagram explaining the principle of the present invention.

In FIG. 1, the present invention comprises a character input means 100 for inputting handwritten kana characters, a recognition means 200 for recognizing kana characters input by the character input means 100, and a recognition means 1 for recognizing kana characters input by the character input means 100.
The object is a handwritten kana-kanji conversion system comprising a kana-kanji conversion means 300 for converting recognized kana characters of 00 into kanji, and a display means 400 for displaying the conversion result of the kana-kanji conversion means 300.

Regarding such a handwritten kana-kanji conversion method, in the present invention, when displaying the conversion result of the kana-kanji conversion means 300 on the display means 400, by specifying an unnecessary portion in the conversion result, the remaining portion excluding the unnecessary portion is displayed. In this embodiment, an unnecessary character erasing means 500 is provided which validates the input kanji and determines the input kanji.

This unnecessary character erasing means can erase, for example, an unnecessary part of the displayed conversion result by pointing with a pen for writing characters.

[Operation] In the handwritten kana-kanji conversion method of the present invention having such a configuration, by simply specifying the unnecessary part of the converted kanji based on the recognition of kana characters, the remaining part after deleting the unnecessary part can be deleted. It can be confirmed as a valid conversion result, and unnecessary parts can be deleted by inputting idioms.When inputting kanji with many homonyms, there is no need to change from input mode to edit mode to delete unnecessary parts. , it is possible to input the desired kanji by erasing unnecessary parts of the conversion result while in the input mode, and it is possible to input sentences efficiently.

[Embodiment] FIG. 2 is a block diagram showing an embodiment of the present invention.

In FIG. 2, reference numeral 1 denotes a handwritten character entry section as a character input means using a tablet or the like, in which kana characters are entered using a pen for character entry. 2 is a conversion instruction section, which indicates whether or not to perform kana-kanji conversion. 3 is a recognition unit which recognizes the kana characters written in the handwritten character entry unit 1 and outputs one or more recognition candidates as recognition results.

A recognition result holding unit 4 holds one or more recognition candidates of the written Kana characters recognized by the recognition unit 3 as recognition results. Reference numeral 5 denotes a recognition next candidate selection instructing unit, which instructs selection of the next candidate when the recognition result of the first candidate held in the recognition result holding unit 4 is different from the handwritten kana character. 6 is a kana-kanji conversion unit which converts kana characters into one or more kanji based on the recognition result of the kana characters held in the recognition result holding unit 4 while the conversion instruction unit 2 issues a conversion instruction.

A conversion result holding unit 7 holds one or more conversion results converted by the kana-kanji conversion unit 6.

8 is a conversion next candidate selection instructing unit, which instructs selection of the next candidate when the first candidate held in the conversion result holding unit 7 is different from the desired kanji. Reference numeral 9 denotes a display unit using a CRT or the like, which displays the first candidate for the recognized kana character obtained by the recognition result holding unit 4 when the conversion instruction unit 2 does not instruct kana-kanji conversion; In the display state of one candidate, each time a next candidate selection instruction is given from the recognition next candidate selection instruction unit 5, the second candidate, third candidate, and so on are sequentially switched and displayed. In addition, when a kana-kanji conversion instruction is given by the conversion instruction section, the display section 9 displays the conversion result of the first candidate held in the conversion result holding section 7 in reverse video, and displays the first candidate in reverse display. In this state, each time a next candidate selection instruction is given from the conversion next candidate selection instruction unit 8, the second candidate, third candidate, etc.
Display the conversion results in reverse video. Further, reference numeral 10 denotes a confirmation instruction section, and when a confirmation instruction is given by the confirmation instruction section 10 while the conversion result of the conversion result holding section 7 is highlighted on the display section 9, the confirmation instruction section 10 cancels the inversion display of the conversion result; Confirm the conversion result as input kanji.

Such a configuration is the same as the conventional system, but in addition to this, an unnecessary character erasing section 11 is newly provided in the present invention. The unnecessary character erasing unit 11 specifies an unnecessary part of the conversion result while the conversion result of the conversion result holding unit 7 is displayed in reverse video on the display unit 9, thereby adding information indicating an unnecessary character to the specified unnecessary character. It has a function to add a specified character and change the specified character part to a blank inverted display. Here, the unnecessary character portion is designated by the unnecessary character erasing section 11 by using the pen used for writing kana characters in the handwritten character entry section 1 on the display section 9.
By pointing to the unnecessary part of the conversion result that is displayed in reverse video, the character part specified by the pen can be displayed as a blank inverted display.

In this way, when the confirmation instruction section 11 issues a confirmation instruction with the unnecessary character deletion section 11 displaying the unspecified unnecessary part as a blank inverted display, the conversion result holding section 7 will display only the remaining characters to which no unnecessary character specification information has been added. is set to be valid, and only the valid characters are de-inverted on the display section 9 and displayed as confirmed.

Next, the processing operation according to the embodiment of FIG. 2 will be explained with reference to the operation flow diagram of FIG. 3.

In FIG. 3, first in step S1, kana characters are written in the handwritten character entry section 1 with a pen, and then in step S1
In step S2, the written kana characters are recognized by the recognition unit 3, and the recognition result consisting of one or more recognition candidates obtained as a recognition result is held in the recognition result holding unit 4 in step S3.

Next, in step S4, the presence or absence of a kana-kanji conversion instruction is checked, and if kana-kanji conversion is not instructed, the process proceeds to step 313, and the first one held in the recognition result holding unit 4 is checked.
The candidate recognition results are displayed in kana on the display section 9. Of course, regarding the kana display in step S13, if a kana display different from the handwritten character is performed, the recognition result holding unit 4 is instructed to select the next candidate by the recognition next candidate selection instruction unit 5
The next recognition result will be selected and displayed.

On the other hand, if the conversion instruction section 2 instructs kana-kanji conversion, the process proceeds from step S4 to step S5, where the kana-kanji conversion section 6 performs kana-kanji conversion on the recognition result of the first candidate held in the recognition result holding section 4. Then, one or more conversion results obtained by this kana-kanji conversion are held in the conversion result holding section 7 in step S6. Subsequently, in step S7, the first candidate conversion result held in the conversion result holding section 7 is displayed in reverse on the display section 9.

Next, in step S8, the recognition next candidate selection instructing unit 5 checks whether there is an instruction to select the next recognition candidate. If there is an instruction to select the next recognition candidate, the process advances to step S14, where the recognition result holding unit 4 selects the next recognition result. Select a candidate and repeat step S
Returning to step 5, the newly selected recognition next candidate (kana character) is converted to kana-kanji, the conversion result is held in step S6, and the converted kanji that is the first candidate of the conversion result is highlighted in step S7. Become.

On the other hand, if there is no instruction to select the next recognition candidate in step S8, the process proceeds to step S9, and it is checked whether the next conversion candidate selection instructing unit 8 has instructed the selection of the next conversion candidate. If there is an instruction to select the next candidate for conversion, the process proceeds to step S'15, where the next candidate for conversion is selected from the conversion result holding section 7, and the selected kanji character as the next candidate for conversion is displayed in reverse video at step S7.

If there is no instruction to select the next candidate for conversion in step S9, the process advances to step S10, and the check is made to see if an unnecessary character has been specified by the unnecessary character erasing unit 11 with /v. If there is a confirmation instruction, the process proceeds to step 812, where the highlighted display is canceled and the kanji that is the conversion result for which the confirmation instruction is made is confirmed as the input kanji.

On the other hand, step 310G: Unnecessary character erasing section 11
If it is determined that unnecessary characters are specified by
Proceeding to step 16, information indicating that the specified portion is an unnecessary character is added in the conversion result holding section 7, and the unnecessary character specified portion is displayed in reverse with a blank space on the display section 9. Next, in step S17, the confirmation instruction section 10 checks whether there is a confirmation instruction, and if there is a confirmation instruction, the process proceeds to step 318, where the conversion result holding section 7 validates only the characters to which no unnecessary character specification information is added. , only the valid characters are displayed on the display section 9 with their inversion removed.

This step 810. The processing of S16 to S18 will be specifically explained with reference to FIG. 4 as follows.

FIG. 4 shows the handwritten character entry section 1 and display section 9 in the embodiment shown in FIG. , "odd number" is input to perform processing to delete unnecessary parts.

First, as shown in Figure 4 (a), write "Kisuu" in kana characters on the handwritten character entry section 1, and press the "conversion" menu with the pen to instruct kana-kanji conversion. "Odd number" is highlighted in 9.

Next, as shown in Figure 4(b), to erase unnecessary characters, press the highlighted "odd number" with the pen.
The display switches to an inverted display with the specified unnecessary characters blank. Next, as shown in Figure 4 (C), when you press the "Confirm" menu with the pen, the display switches to a display in which only the remaining valid characters that become "odd" are uninverted, and unnecessary characters are deleted to display "odd". You can input kanji.

The process of inputting kanji with many homonyms and deleting unnecessary parts can be done in input mode, and can be done by changing the menu from input mode to edit mode as before. There is no need to delete characters.

[Effects of the Invention] As explained above, according to the present invention, by pointing out an unnecessary character portion with, for example, a pen while displaying a kana-kanji conversion candidate, the unnecessary character is erased, and the remaining characters are made valid. Only valid characters that have been confirmed as candidates can be input, making it easy to input sentences by handwriting and converting them to kana and kanji, and efficiently inputting sentences.
