Abstract

A basic dictionary contains information for character recognition processing on characters which are relatively high in use frequency and an additional dictionary contains information for character recognition processing on characters which are relatively low in use frequency. A dictionary information alteration means reads information for character recognition processing out of the additional dictionary when the information for character recognition processing on a character whose character code is inputted by a character code input means is stored in the additional dictionary, adds an attribute indicating that the character is an object of character recognition processing, and stores the information in an alteration dictionary. A character recognition means performs character recognition as to handwriting data inputted from a handwriting input means by referring to the basic dictionary and alteration dictionary.

Description

text input device

There are two types of character input devices for inputting characters as handwriting data and character codes. The present invention relates to a character input device for performing character recognition processing on inputted handwriting data.

Generally, in a character input device that inputs characters as handwriting data, it is necessary to perform character recognition processing on the handwriting data input by the user, and output one or more candidate marks.

In the character recognition process, candidate identifiers are found by referring to a dictionary prepared in advance for the character recognition process. That is, the standard handwriting patterns and character codes of general characters with relatively high frequency of use are stored in a dictionary for character recognition processing as information for character recognition processing. The character code corresponds to the standard handwriting pattern with relatively high consistency of the handwriting data input by the user.

However, when the user is a person who likes to use unfamiliar characters, the coincidence degree between the handwriting data input by the user and the standard handwriting pattern of the characters desired by the user is reduced, so that there is a problem that candidate marks cannot be output.

Therefore, a technique is provided in which when a user inputs his own handwriting data and a character code corresponding to the handwriting data, the handwriting data and the character code are associated and stored separately as information for character recognition processing , so even if the user is a person who likes to use unfamiliar characters, the candidate identifier desired by the user can be output.

Thus, according to the above-mentioned prior art, it is possible to improve the user's convenience at the time of handwriting input.

However, there are still unresolved problems with handwritten text input. That is, since the character recognition processing is performed with reference to the information for character recognition processing stored in a dictionary for character recognition processing prepared in advance (when the above-mentioned prior art is applied, there is also information for character recognition processing input by the user), so For example, when the user inputs handwriting data, if the information for character recognition processing of the desired character is not stored in the dictionary for character recognition processing, the desired candidate mark cannot be output, so there is a problem of inconvenience. In addition, for example, when the user inputs handwriting data, since the character recognition processing information of characters other than the desired characters is stored in the dictionary for character recognition processing, unnecessary candidate tags will be output, and in order to determine the characters, it is necessary to It is necessary to select and indicate a desired candidate logo from the output candidate logos, so there is also a problem of inconvenient use.

On the other hand, in a character input device, for a candidate mark that is a result of character recognition processing of an input character code or input handwriting data, kana-kanji conversion processing is sometimes performed, and kanji or kana-kanji mixed characters are used as The conversion result is output.

The kana-kanji conversion process is also performed by referring to the dictionary for the kana-kanji conversion process prepared in advance like the character recognition process. There are various usage methods, but the output of the conversion result is the same, so the conversion result desired by the user cannot be output, and therefore, there is a problem of inconvenience in use.

Therefore, for example, as described in JP-A-62-77672 and JP-A-3-116366, there are provided technologies capable of deleting a specific word in a dictionary for kana-kanji conversion processing and changing kana. This is realized by preparing another dictionary for correcting, adding, and deleting the dictionary for kana-kanji conversion processing.

However, the above-mentioned prior art is for correcting, adding, and deleting a dictionary for kana-kanji conversion processing, and is not suitable for a dictionary for character recognition processing that is referred to in character recognition processing.

Therefore, the purpose of the present invention is to provide a text input device, which can output the candidate logo desired by the user, thereby improving the convenience of the user when inputting handwritten text. Specifically, it is possible to output the candidate identifiers required by the user and not to output the candidate identifiers not required by the user.

In order to achieve the above object, the present invention utilizes a character input device to carry out character recognition processing. Said character input device is equipped with: a handwriting input device for inputting characters as handwriting data; Character code input device for input; a character recognition device that performs character recognition processing on the handwriting data input by the above-mentioned handwriting input device and outputs more than one candidate logo; at least displays the handwriting data input by the above-mentioned handwriting input device, and utilizes the above-mentioned A display device for the character code input by the character code input device and the candidate mark output by the above-mentioned character recognition device; the standard handwriting pattern and the character code of the characters with higher frequency of use are stored as the basic dictionary for character recognition processing information; and An additional dictionary that stores standard handwriting patterns and character codes of less frequently used characters as information for character recognition processing. In addition, in the above-mentioned character input device of the present invention, the character recognition processing information of the characters of the character code input by the above-mentioned character code input device is read out from the above-mentioned additional dictionary when the information for character recognition processing of the characters of the character code input by the above-mentioned character code input device is stored in the above-mentioned additional dictionary. A dictionary information changing device that adds an attribute (hereinafter referred to simply as an additional attribute) representing a mark that is an object of character recognition processing to information for processing; In the modified dictionary of processing information, the character recognition device performs character recognition processing by referring to the character recognition processing information stored in the basic dictionary and the character recognition processing information stored in the modified dictionary with additional information added thereto.

In addition, among the candidate marks output by the above-mentioned character recognition device and displayed by the above-mentioned display device, for the candidate recognition of a mark that is instructed not to be displayed from the outside, if the character recognition processing corresponding to the candidate mark If information is stored in the above-mentioned basic dictionary, then the above-mentioned dictionary information changing device of the present invention reads the information for character recognition processing from the basic dictionary and adds an attribute indicating that it is not an object of character recognition processing (hereinafter In addition, if the text recognition processing information corresponding to the candidate identifier is stored in the above-mentioned change dictionary with an additional attribute, then the dictionary information changing device changes the additional attribute to a prohibited attribute , and the above-mentioned change dictionary stores information for character recognition processing to which the prohibition attribute is added by the above-mentioned dictionary information change means.

In addition, the present invention can also change the content of the above-mentioned change dictionary.

Therefore, in the present invention, when an instruction to change the flag of the content of the above-mentioned modified dictionary is input from the outside, the display device can display the content of the above-mentioned modified dictionary in an overview. In the content of the above-mentioned change dictionary, when the information for character recognition processing with an additional attribute indicated is selected from the outside, the additional attribute is changed to the prohibited attribute, and the character recognition with the prohibited attribute is selected When processing information, if the information for character recognition processing is stored in the above-mentioned basic dictionary, then the dictionary information changing means deletes the information for character recognition processing from the above-mentioned change dictionary, and if the information for character recognition processing is stored in into the above-mentioned additional dictionary, the above-mentioned changing device will change the prohibited attribute into an additional attribute.

According to the present invention, when the user inputs a character code of a character not targeted for character recognition processing, the information for character recognition processing of that character can be targeted for character recognition processing and output as a candidate for recognition from the next time.

In addition, when the user selects a candidate mark that he does not want to display from among the displayed candidate recognitions, the information for character recognition processing corresponding to the candidate recognition can be deleted from the target of character recognition processing from the next time, and the output as candidate recognition.

Therefore, the user can output a desired candidate mark and not output an unnecessary candidate recognition, so that the user's convenience at the time of handwritten character input can be improved.

The dictionary information changing means 106 refers to the additional dictionary 107 and stores the information for character recognition processing of the character code input by the character code input means 105 in the changing dictionary 104 . The details of the additional dictionary 107 will be described later.

The output device 108 outputs the input process and results of characters in a form that can be seen by human eyes by displaying and printing. In this embodiment, it is realized by displaying on the input display panel 203 . The output device 108 has font data corresponding to character codes.

Next, the basic dictionary 103, the additional dictionary 107, and the modified dictionary 104 will be described with reference to FIGS. 4 to 6 .

FIG. 4 is a diagram showing an example of the content of the basic dictionary 103. As shown in FIG.

As shown in FIG. 4 , in the basic dictionary 103 , standard handwriting patterns and character codes of common characters that are frequently used are stored as information for character recognition processing, and the contents thereof will not change after initialization. The standard handwriting pattern is a standard handwriting pattern that the character recognition device 102 compares and uses when performing character recognition processing. In the example of FIG. 4 , information for character recognition processing of "え", "元", and "守" is stored.

FIG. 5 is a diagram showing an example of the contents of the additional dictionary 107. As shown in FIG.

As shown in Figure 5, in the additional dictionary 107, the standard handwriting pattern and the character code of the characters that are not stored as the information for character recognition processing in the basic dictionary 103 are stored in the form of character recognition processing information, and its content is in the initialization state Not changed after that. In the example of FIG. 5 , information for character recognition processing of "the" is stored.

FIG. 6 is a diagram showing an example of the contents of the change dictionary 104 .

Fig. 6(a) shows the initialization state of the change dictionary 104, and in the initialization state, nothing is stored in the change dictionary 104. And, as the user uses the character input device of the present embodiment, as shown in Fig. 6 (b)～Fig. It is stored as an attribute of information (whether or not information for character recognition processing is to be targeted for character recognition processing).

In the text input device of the present embodiment, the basic dictionary 103 and the additional dictionary 107 whose content is constant can be realized with non-rewritable storage devices such as cheap ROM, and only the change dictionary 104 whose content can be changed is used RAM and hard disk etc. A rewritable storage device is implemented.

Next, the user operation sequence of this embodiment will be described with reference to FIG. 7 .

Here, it is assumed that at least kana character recognition processing information is stored in the basic dictionary 103 and that the character recognition processing information of the character "Zhi" is not stored in the basic dictionary 103 but is stored in the additional dictionary 107 .

When the contents of the change dictionary 104 were in an initialization state as shown in Figure 6 (a), when the user wanted to input the word "Zhi", at first, as shown in Figure 7 (a), the input text was handwritten, and the writing The pen 202 presses the recognition button among the software buttons 303 . Like this, character recognition device 102 just carries out character recognition processing to the handwritten character (handwriting data) of input, but, because all do not store the character recognition processing information of this character of "Zhi" in basic dictionary 103 and change dictionary 104, so , and output only "e" in the information for character recognition processing stored in the basic dictionary 103 as a candidate identifier. Therefore, "え" is displayed as a candidate mark in the handwritten character input display frame 302 as shown in FIG. 7( b ).

Since the user cannot obtain the desired candidate mark, as shown in FIG. Input the pseudonym "こち" by handwriting, and as shown in FIG. 7( d), press the transfer button in the software button 303 with the writing pen 202. Like this, character recognition device 102 just carries out character recognition process to the handwritten character (handwriting data) of input, and " こ ち " is output as candidate mark, and then, character code input device 105 is to the candidate mark that character recognition device 102 outputs ( "こち") carries out kana-kanji conversion processing, and the word "zhi" is output as the conversion result. Therefore, in the handwritten character input display frame 302, as shown in FIG. 7(e), the character "Zigzag" is displayed as a conversion result. In addition, the character "Zhi" can also be output by pinyin conversion or Wubi glyph conversion. Of course, dictionaries (not shown in the figure) for each conversion should be provided in the device.

In this embodiment, when it is judged that the user can handwriting input the result of kana-kanji conversion, that is, the character code input by the character code input device 105 is the character "Zhi", the character recognition processing information of the character "Zhi" is used as the character The object to be recognized and processed, so that the character recognition device 102 can output the candidate mark of "Zigzag" from next time.

That is, the dictionary information converting means 106 reads the information for character recognition processing of "it" from the additional dictionary 107, adds an attribute ("addition") indicating that it can be used as an object of character recognition processing, and stores it in the modification dictionary 104. Inside. Like this, the content of change dictionary 104 just becomes the state shown in Fig. 6 (b), thereby, from next time just can output the candidate mark of this character of "Zhi".

After changing the content of the dictionary 104 into the state shown in Figure 6(b), when the user wants to input the character "Zhi", as shown in Figure 7(f), input the character by handwriting, use the writing pen 202 to press Identify button in software button 303 . In this way, the character recognition device 102 performs character recognition processing on the input handwritten characters (handwriting data). At this time, although the information for character recognition processing of "the" is not stored in the basic dictionary 103, since the information is written in the form of "addition", Attributes are stored in the modification dictionary 104, so the character recognition processing information "え" stored in the basic dictionary 103 and the character recognition processing information "え" stored in the modification dictionary 104 with the attribute of "additional" can be used as Candidate ID output. Therefore, in the handwritten character input display frame 302, as shown in FIG. 7(g), "え" and "之" are displayed as candidate marks.

In this embodiment, as the character code input device 105, an example of performing kana-kanji conversion processing is shown, but it is also possible to press the radical button in the software button 103 to input the character code through the radical input, or use a numerical value Enter character codes such as location and JIS. In addition, character input can also be realized through external devices such as a keyboard and a Chinese character input board.

In this way, according to this embodiment, as far as the characters whose character recognition processing information is not stored in the basic dictionary 103, once the user uses the character code input device 105 to input the character code of the character, then the character recognition processing information of the character It becomes the object of the character recognition process, and the candidate mark recognition of the character can be output from the next time, so the user's convenience at the time of handwritten character input can be improved.

In addition, in the present embodiment, the dictionary information changing means 106 automatically stores the information for character recognition processing of the characters whose character codes are input using the character code input means 105 in the changing dictionary 104 with the attribute of "additional". Store only when user enters instructions.

Generally, the types of Chinese characters input by the user are limited, and among the Chinese characters stored in the basic dictionary 103 as information for character recognition processing, there are still a large number of Chinese characters that the user has not input by handwriting or that the user does not use. Therefore, characters not used by the user may be included in the candidate marks output by the Chinese character recognition device 102 .

Therefore, in this embodiment, the information for character recognition processing of characters not used by the user may be deleted from the objects of character recognition processing, so that the candidate identifiers for the characters are not output. In addition, in this embodiment, the information for character recognition processing deleted from the object of character recognition processing can be used as the object of character recognition processing again, so as to output the candidate identifier of the character corresponding to the information for character recognition processing again. In this embodiment, as described above, the attribute of "addition" may be canceled for the character whose character recognition processing information is stored in the modification dictionary 104 with the attribute of "addition".

First, an example of deleting characters not used by the user from the target of character recognition processing will be described with reference to FIG. 8 .

When the content of change dictionary 104 is the state shown in Figure 6 (b), when the user wants to input the word "Yuan", at first, as shown in Figure 8 (a), by handwriting input characters, use writing pen 202 to press Press the identification button in the software button 303. Like this, character recognition device 102 just carries out character recognition processing to the handwritten character (handwriting data) of input, but at this moment, because the character recognition processing information of " element " and " allow " is stored in the basic dictionary 103, so " Yuan" and "allow" are output as candidate identifiers. Therefore, in the handwritten character input display frame 302, as shown in FIG. 8(b), "Yuan" and "Yun" are displayed as candidate marks.

When the user judges not to use the word "allow" and does not want to display the candidate mark of "allow", as shown in Figure 8 (c), use the writing pen 202 to press the forbidden button in the software button 303, and then, As shown in FIG. 8( d ), use the writing pen 202 to select the candidate mark indicating the word "allow".

Like this, as shown in Fig. 8 (e), after deleting the candidate mark of word "Yuan", after the user selects and indicates the candidate mark of "Yuan", as shown in Fig. 8(f), the obtained Hope the word "Yuan" in this text. At this time, in this embodiment, the information for character recognition processing of the word "allow" is deleted from the object of character recognition processing, and the candidate identification of the character "allow" will not be output from the next time.

That is, the dictionary information changing means 106 reads the character recognition processing information of "allow" from the basic dictionary 103, and stores it in the modification dictionary 104 as an attribute ("prohibited") indicating the flag to be deleted from the object of the character recognition processing. . Like this, the content of change dictionary 104 just becomes the state shown in Fig. 6 (c), and just can no longer output the candidate sign of " allow " from next time.

After changing the contents of the dictionary 104 into the state shown in Figure 6(c), when the user wants to input the word "Yuan", as shown in Figure 8(g), input the character by handwriting, use the writing pen 202 to press Identify button in software button 303 . Like this, character recognition device 102 just carries out character recognition processing to the handwritten character (handwriting data) of input, but here, although the character recognition processing information of this character of " allow " character is stored in the basic dictionary 103, because " prohibited " The attribute of is stored in the change dictionary 104, so only the "meta" character stored in the basic dictionary 103 as information for character recognition processing is output as a candidate identifier. Therefore, in the handwritten character input display frame 302, as shown in FIG. 8(h), only "yuan" is displayed as a candidate tag.

In addition, in this embodiment, the character recognition device 102 does not refer to the information for character recognition processing, and even if it does, it does not need to output it as the first candidate identifier. At this time, the candidate recognition is output in the order of "Yuan" and "Yuan".

Next, an example will be described in which the attribute "prohibited" stored in the change dictionary 104 is canceled and the character deleted from the object of the character recognition processing is again the object of the character recognition processing with reference to FIG. 9 .

When the contents of the change dictionary 104 are in the state shown in FIG. Press the dictionary button in the software button 303. Then, as shown in Figure 9(b), the content stored in the change dictionary 104 can be displayed in an overview, so the user can use the writing pen 202 to select and indicate that he/she wants to cancel, as shown in Figure 9(c). The "forbidden" attribute text("allow").

Then, the dictionary information changing means 106 deletes the information for character recognition processing of "Yun" from the changing dictionary 104 . Like this, the content of change dictionary 104 just becomes the state shown in Fig. 6 (b), because the character recognition processing information of "allow" is stored in the basic dictionary 103, so, the character recognition processing information of "allow" this character Just become the object of character recognition processing, and just can output the candidate mark of this character of " allow " word from next time.

After changing the content of the dictionary 104 into the state shown in Figure 6(b), when the user wants to input the word "Yuan", as shown in Figure 9(d), input the character by handwriting, use the writing pen 202 to press Identify button in software button 303 . In this way, the character recognition device 102 performs character recognition processing on the input handwritten characters (handwriting data), and outputs "Yun" and "Yuan" stored in the basic dictionary 103 with character recognition processing information as candidate tags. Therefore, in the handwritten character input display frame 302, as shown in FIG. 9(e), "Yun" and "Yuan" are displayed as candidate marks.

Here, if the user uses the writing pen 202 to select the candidate mark indicating the word "Yun", the word "Yun" can be obtained as shown in FIG. 9(f).

When the character recognition processing information of the character whose attribute of "forbidden" is removed is not stored in the basic dictionary 103, as mentioned above, the character code is a character that can be input by the character code input device 105, which means The information for character recognition processing of this character is stored in the additional dictionary 107. Therefore, in order to make the information for character recognition processing of this character an object of character recognition processing, the dictionary information changing means 106 does not change the information for character recognition processing of this character from Change dictionary 104 is deleted, and its attribute is changed to "append".

Next, an example in which the attribute "add" stored in the change dictionary 104 is canceled and the attribute is deleted from the object of character recognition processing will be described with reference to FIG. 10 .

When the content of the change dictionary 104 is in the state shown in FIG. The dictionary button among the software buttons 303 is pressed. Thus, the content stored in the change dictionary 104 can be displayed in an overview as shown in Figure 10 (b), so the user can use the writing pen 202 to select and indicate to cancel the " Append the text ("of") of this attribute.

Then, the dictionary information changer 106 changes the attribute of the character recognition information of "of" stored in the change dictionary 104 to "prohibited". Like this, the content of change dictionary 104 just becomes the state shown in Fig. 6 (d), and the character recognition processing information of this character of "Zhi" is deleted from the object of character recognition processing, and just no longer output from next time. Candidate identification of the character "Zhi".

After changing the content of the dictionary 104 into the state shown in Figure 6(d), when the user wants to input the character "え", he can input the character by handwriting as shown in Figure 10(d), and press the stylus 202 to Press the identification button in the software button 303. Like this, character recognition device 102 just carries out character recognition processing to the handwritten character (handwriting data) of input, although " it " character recognition processing information is stored in the change dictionary 104 here, but because its attribute is " forbid ", so, Only "e" stored in the basic dictionary 103 as information for character recognition processing is output as a candidate tag. Therefore, in the handwritten character input display frame 302, as shown in FIG. 10(e), only "え" is displayed as a candidate mark.

Next, the operation flow of this embodiment will be described with reference to FIGS. 11 to 14 .

Fig. 11 is a flowchart of the overall operation of this embodiment.

As shown in FIG. 11 , the character input device of this embodiment receives user input (step 1101 ) and determines the type of the input (step 1102 ).

When the type of input is the input of handwriting data, character recognition device 102 just refers to change dictionary 104 and basic dictionary 103 (step 1103, step 1104) this handwriting data is carried out character recognition processing, and output candidate mark (step 1105). The candidate marks output by the character recognition device 102 are displayed in the handwritten character input display frame 302 .

Here, when a certain one of the candidate logos displayed in the handwritten text input display frame 302 has been selected and indicated, and the forbidden button in the software button 303 is pressed, it means that the sign indicating that the candidate logo is not displayed has been input (step 1106 ), so the dictionary information changing device 106 just carries out prohibition registration processing (step 1107), and returns to step 1105, when the prohibition button in the software button 303 is not pressed, this candidate mark just becomes the literal after confirming (step 1108 ). The registration prohibition process will be described later.

In addition, when the type of input is character code input by the character code input device 105, the dictionary information changing device 106 performs additional registration processing (step 1109). The additional registration processing will be described later.

In addition, when the type of input is to press the dictionary button in the software button 303, it means to change the content of the dictionary 104, so the dictionary information changing device 106 performs the dictionary information changing process (step 1110). The dictionary information change processing will be explained later.

Fig. 12 is an operation flowchart of additional registration processing.

As shown in Fig. 12, the dictionary information changing device 106 first searches the changing dictionary 104 (step 1201), and judges whether the character recognition processing information of the characters input by the character code input device 105 has been pressed "addition". The attributes are stored in the change dictionary 104 (step 1202).

When utilizing the character code input device 105 with the character recognition processing of the character input of the character code mode to store in the change dictionary 104 by the attribute of "additional", the process ends, and if it is not stored in the change dictionary 104 , the basic dictionary 103 is searched (step 1203), and it is judged whether the information for character recognition processing is stored in the basic dictionary 103 (step 1204).

When utilizing the character code input device 105 to store in the basic dictionary 103 when the character recognition processing information of the characters input in the character code mode is stored in the basic dictionary 103, the processing ends immediately, and when it is not stored in the basic dictionary 103, it means that the character recognition Since the information for processing is stored in the additional dictionary 107, the information for character recognition processing is read from the additional dictionary 107 and stored in the modification dictionary 104 as an attribute of "additional" (step 1205).

Fig. 13 is an operation flowchart of prohibition registration processing.

As shown in FIG. 13, the dictionary information changing device 106 first searches the changed dictionary 104 (step 1301), and judges whether the character recognition processing information of the characters that are not displayed as candidate marks, that is, the characters that are deleted from the character recognition processing target is stored. within the changes dictionary 104 (step 1302).

When the character recognition processing information of the character deleted from the character recognition processing object is stored in the change dictionary 104, its attribute is judged (step 1303). When its attribute is "prohibited", the operation ends. When the attribute is "addition", the attribute is changed to "prohibited" (step 1304). In addition, when the information for character recognition processing of the character deleted from the object of character recognition processing is not stored in the change dictionary 104, it means that the information for character recognition processing is stored in the basic dictionary 103, so the basic dictionary The information for character recognition processing is read in 103, and the attribute "prohibited" is stored in the change dictionary 104 (step 1305).

Fig. 14 is an operation flowchart of dictionary information change processing.

As shown in FIG. 14, the dictionary information changing device 106 first shows an overview of the character recognition processing information and its attributes stored in the changed dictionary 104 (step 1401), and receives an instruction to select the character as the changed attribute object (step 1401). 1402).

Then, judge the attribute (step 1403) of the character recognition processing information of the received character, if it is "additional" attribute, just change its attribute to "prohibited" (step 1404), if it is "prohibited" attribute, just change the basic The dictionary 103 performs a search (step 1405), and judges whether information for character recognition processing of the character is stored in the basic dictionary 103 (step 1406).

If the character recognition processing information of the received character is stored in the basic dictionary 103, the character recognition processing information of the character is deleted from the change dictionary 104 (step 1407), and if it is not stored in the basic dictionary 103, The attribute of the information for character recognition processing of the character is changed to "add" (step 1404).

In this embodiment, a process of deleting only the information for character recognition processing stored in the basic dictionary 103 from the target of the character recognition processing can be performed separately. This processing can be performed without the character code input device 105 and the additional dictionary 107 .

In addition, in the present embodiment, for the characters whose character recognition processing information is stored in the change dictionary 104 with the attribute of "prohibited", even if a character code is input by the character code input device 105, it is not converted into character recognition. Handle the object's disposition. However, the attribute of "prohibited" may be canceled at the time of inputting a character code by the character code input device 105, and the process of switching to a character recognition processing target may be performed.

In addition, in this embodiment, when the information for character recognition processing of the character whose attribute has been canceled is not stored in the basic dictionary 103, the character of the character is not changed from the changed dictionary 104. The information for identification processing is deleted and its attribute is changed to “additional”, however, it may be deleted from the change dictionary 104 . This is because even if the information for character recognition processing is deleted from the modification dictionary 104, when a character code is input using the character code input device 105, the attribute "addition" can be stored in the modification dictionary 104 again.

In this embodiment, the information for character recognition processing of the character whose attribute has been removed from the "attachment" is changed to the attribute of "prohibited". Delete with information. This is because the information for character recognition processing is stored in the additional dictionary 107, so when the information is deleted from the change dictionary 104, it is also deleted from the target of the character recognition processing. At this time, when the character code is input by the character code input device 105, the attribute "addition" is stored in the modification dictionary 104 again.

In this embodiment, word processing information is stored in the modified dictionary 104, but the word processing information can also be stored in the storage location of the basic dictionary 103 or the additional dictionary 107 instead of storing the word processing information.

In addition, in this embodiment, an example in which there is one change dictionary 104 is shown, but a plurality of change dictionaries 104 may be prepared. At this time, the user can select an arbitrary change dictionary 104 from a plurality of change dictionaries 104 . This can be achieved, for example, by providing a software button or the like for selecting the change dictionary 104 . In addition, two modification dictionaries 104 may be prepared, wherein one modification dictionary 104 stores only information for character recognition processing whose attribute is "additional", and the other modification dictionary 104 stores only information for character recognition processing whose attribute is "prohibited". . In this way, it is effective to use only the "additional" attribute or only the "prohibited" attribute. Of course, multiple change dictionaries 104 can also be used at the same time.

As described above, in the character input device of the present invention, for a character input by the user as a character code, information for character recognition processing of the character can be targeted for character recognition processing and output as a candidate flag. In addition, information for character recognition processing corresponding to candidate markers unnecessary to the user may be deleted from the target of character recognition processing, so that the candidate markers may not be output. Therefore, it is possible to improve the user's convenience at the time of handwritten character input.
