Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention not only recognizes a predetermined character, but also allows the user to input the shape of an arbitrary character, number, symbol or figure, and convert that shape into a corresponding character code. The present invention relates to a character recognition device having a recognition character registration method and a registration function (hereinafter referred to as a recognition registration function) that can add recognition characters to be converted.

[0002]

2. Description of the Related Art Conventionally, in a character recognition device having a recognition registration function, when performing recognition registration, a pattern to be registered is input by handwriting and a character code corresponding to this input pattern is defined. In this case, the user is configured to directly input the character code or to input the character code by using a function such as Kana-Kanji conversion.

[0003]

However, in the above-mentioned conventional example, in order to assign the pattern to be registered to the character code, it is necessary to look for the desired code by looking at the character code table, and the procedure until registration is troublesome. there were. Further, when the user uses the recognition registration function, it may be used not only to register unrecognizable characters but also to facilitate recognition of characters having a poor recognition rate for the user. In this case, the user has to memorize the character having a poor recognition rate during normal use, check the pattern and the character code and register the character, which is very troublesome and the operability is poor. Furthermore, since the registration pattern is determined regardless of the character recognition function, the pattern to be registered is registered without noticing that the pattern to be registered is similar to the pattern of characters and symbols that can be recognized by existing recognition processing. However, there is a drawback that the character recognition rate of the existing pattern is reduced.

The present invention eliminates the above-mentioned conventional drawbacks and allows a user to register a recognition pattern with a simple operation without lowering the character recognition rate of an existing pattern. I will provide a.

[0005]

In order to solve this problem, the recognition character registration method of the present invention is a recognition character registration method for registering a new pattern as a recognition character.
By displaying the candidate character string by recognizing the input pattern and selecting a desired character on the display screen from the displayed candidate character string, the selected character is recognized as the recognized character of the input pattern. It is characterized in that a character code stored in advance corresponding to a character is registered.

Further, the character recognition device of the present invention is a character recognition device capable of registering a new pattern as a recognized character, and a display means for recognizing an input pattern and displaying a candidate character string, which is displayed. Selection means for selecting one character from the candidate character string, and registration means for registering a character code corresponding to the selected character as a recognition character of the input pattern. Here, the recognition of the pattern is performed by a plurality of recognition engines. In addition, the plurality of recognition engines includes a radical search recognition engine.

Each of the parts 101 to 107 is in charge of a functional element of user registration in online character recognition, and is roughly classified into a GUI (graphical user.
It is composed of a window application execution part by an interface) and a user dictionary part.

On the initial screen section 101, a list of registered users is displayed so that the owner of the currently set user dictionary can be confirmed. Other functions include a function for instructing to newly register a user and a command for editing registered characters in the user dictionary. The new user registration unit 102 is a unit that performs registration of the new user. The user dictionary editing unit 103 can display a list of characters in the user dictionary, and can instruct each character to be deleted or handwritten. It also includes an instruction function for newly registering characters written by the user.

The new character registration section 104 is a section for registering the character designated by the user dictionary editing section 103. The handwritten character reproduction unit 105 includes the user dictionary editing unit 10
This is a portion for reproducing and drawing the registered characters instructed in 3 in the order of handwriting. The user dictionary unit 106 is a unit that stores registered character information in order to realize the above functions. Here, a plurality of users have different user dictionaries. The recognition candidate output unit 107 is a unit that recognizes a handwritten pattern and returns a character code of a candidate character for the pattern.

FIG. 2 is a diagram showing the transition of the window state of the user registration application. The respective units 201 to 205 represent windows for executing the above-mentioned functions, and the system 206 is a unit to which control is returned when the user registration application is terminated. The arrows in the figure show the flow of control commands by button control in each window. The flow and transition of windows will be described below.

When the "new user registration" command is instructed on the new screen section 201, the new user registration screen section 202 newly appears in the form of a pop-up window. When the "registration &end" command is instructed on the new user registration screen section 202, this pop-up window is erased and the control returns to the new screen section 201 again. When the "edit user dictionary" command is instructed on the new screen section 201, the new screen section 201 is erased and a new user dictionary edit section 203 appears. When the "new character registration" command is instructed here, the new character registration screen section 204 appears in the form of a pop-up window. The character registration operation in this window can be repeatedly executed unless the "end" command is instructed. When "end" is instructed after the characters are registered, the new character registration screen section 204 is erased and the control is transferred to the user dictionary edit screen section 203.

The "character deletion" command on the user dictionary editing screen section 203 can be executed a plurality of times. When the "handwriting reproduction" command is further instructed, the handwritten character reproduction unit 205 appears in the form of a pop-up window.
Reproduction is started at the same time as the window is displayed, and it is possible to repeatedly display it by the "refresh" command. The "end" command closes the handwritten character reproduction section window and returns control to the user dictionary edit screen section. When the "end" command is instructed on the user dictionary edit screen section 203, the window of its own is deleted and the new screen 20
Display 1 on the side. Therefore, the user registration application can be terminated only when the “end” command is instructed on the initial screen unit 201.

As described above, the number of windows related to the user registration application is two when the pop-up windows 202, 204 and 205 are displayed on the screen, and the window 201 or 203 is displayed. When there is one, it is one.

Next, the details of the functions and the flow of processing in each screen will be described with reference to FIG.

(Initial Screen Section) The flow of processing in the initial screen section 101 will be described with reference to the flowchart of FIG. 3 and the display example of FIG.

In FIG. 17, 1701 is a message display area, 1702 is a user name list display and user dictionary owner display area, 1703 is a scroll bar when the registered users cannot fit on one screen, 1
Buttons 704 to 1707 are buttons that can call a function by a pen tap.

When the user registration application is started, a window (initial screen) is created in step 301 of FIG. 3, and at this time, the registered user name is read from the user name index file. This user name index file is a disk file having the structure shown in FIG. 23 and is a readable / writable file. The created window is as shown in FIG. In step 302, the owner of the user dictionary set in the system is determined.

When the owner is determined, step 303
At, the user who is the owner of the user dictionary in the user name display area 1702 is marked. For example, in FIG. 17, the user whose user name is “arai” is the owner. When the processing up to this point is completed, in the flow of FIG. 3, the state step 304 in which there is a command instruction from the user is entered. Here, when the user is directly selected by using a pointing device such as a pen, the process proceeds to step 308 to request the owner change of the user dictionary and change the owner setting.

The operation by the button command in FIG. 17 will be described. If the "edit user dictionary" button 1705 is pointed to, the branch 306 from step 304 is selected, and control is passed to the user dictionary edit routine. 17
If you point to the "New user registration" button 04, branch 3
07 is selected and control is transferred to the new user registration routine. If the "Cancel" button 1706 is designated, the user dictionary setting change by user name selection that has been performed so far is invalidated, and the user dictionary setting is returned to the state of step 302 before this application is started. If the "end" button 1707 is pointed to, branch 305 is selected to end the current user registration application.

(New User Registration Screen Section) The flow of processing in the new user registration screen section 102 will be described with reference to the flowchart of FIG. 4 and FIG.

Reference numeral 1801 in FIG. 18 is a user name input area for inputting a user name, 1802 is a function button for canceling the input of the user name, and 1803 is a function button for registering the input user name and terminating this window. is there.

The initial screen portion 1704 shown in FIG.
18 is displayed, a pop-up window shown in FIG. 18 is displayed in step 401. After that, the process moves to the state step 402 where the user has a command instruction. When an event signal due to pen down is detected in the user name input area 1801, the branch 40
4 is selected to call an existing recognition routine. Using this, the character handwriting drawn in the user name input area is subjected to online character recognition processing, the character data is converted into a character code (step 407), and a command instruction is awaited step 4
It returns to the state of 02.

When there is an instruction from the "register &end" button command 1803, the branch 403 is selected, and step 406 is executed.
The user name converted into the user name input area is judged as a new user name and is additionally registered in the user name index file. After that, it erases its own window and returns control to the initial screen section again. On the other hand, when the "Cancel" button command 1802 is instructed, the branch 405 is selected, all the characters entered in the user name input area are erased in step 408, and the state of step 402 in which the user name input command instruction is waited again Return to.

(User dictionary editing section) User dictionary editing section 1

The branch 306 is selected in step S6, and the flow operation of FIG. 5 starts. In step 512, the designated user dictionary is copied and copied as a backup and stored separately. This is so that the dictionary editing work can be canceled. Next, in step 501, the user dictionary is opened, and in step 502, the character code in the user dictionary is read into the buffer area.

Here, in order to make the characters in the user dictionary correspond to the characters to be displayed in a one-to-one correspondence, a character code correspondence table is created in step 601 of FIG. For example,
When the registered characters are 6 characters, it becomes as shown in FIG. The meaning of creating this character code correspondence table is that if there are multiple dictionary character data with the same character code, editing the characters with the "Delete" and "Reproduce" commands will cause the dictionary data to be This is because the search cannot be performed uniquely.

Based on this character code correspondence table, the user dictionary edit screen shown in FIG. 21 is displayed in step 503. The character code read at this time is the step 5
No. 04 is displayed in the registered character list display area 2101. After that, the process enters a step 505 of waiting for a command from the user.

When a signal due to pen down or the like is detected in the registered character list display area 2102, the branch 506 is selected and the character at the pen-down location is selected. The display number on the character code table shown in FIG. 24 is obtained from the position information of the selected character. The storage location of the dictionary character data actually stored in the user dictionary is determined from the display number, and the dictionary character data information to be edited is obtained.

"Character registration" button command 21 in FIG.
When 04 is designated, branch 507 is selected, and control is passed to the new character registration routine of branch 701 through the flow of FIG. When the "delete character" button command 2105 is designated, the branch 508 is selected, and step 801 of FIG. 8 is selected.
Then, it is determined whether or not the character in the registered character list display area is selected. If not selected, the process returns to the command instruction waiting state of step 505. If it has already been selected, in step 802 the dictionary data storage location of the character to be deleted is searched for using the character code correspondence table described above. When found, the dictionary character data stored in the actual user dictionary is deleted. At this time, the content of the user dictionary is changed, and at the same time, the character code correspondence table is also changed, and the process proceeds to step 504 to update the character display in the registered character list display area.

"Handwriting reproduction" button command 2 in FIG.
When 106 is instructed, the branch 509 is selected, and the process proceeds to step 901 in FIG. Here, if a character is selected, the control shifts to the handwriting reproduction routine, and if not selected, the state returns to the state of waiting for the character to be selected again.

"Cancel" button command 2107 in FIG.
Is selected, the branch 510 is selected in FIG.
In step 1001, it is determined whether a character in the registered character list display area is selected, and if it is selected, the character is invalidated in step 1002, and no character is selected on the display. After the state, the contents of the registered dictionary are returned to the state before the dictionary editing window was started in step 1003, and the control is transferred to step 501 in FIG. By this operation, editing work can be resumed again.

"End" button command 2108 in FIG.
Prompts you to close the user dictionary edit window,
The operation of returning the control to the previous initial screen portion is performed (branch 511).

(New Character Registration Unit) New Character Registration Unit 104
11 shows the flow of processing in FIG. 11 and FIG.
This will be described with reference to FIG.

In FIG. 19, 1901 is a message display area, 1902 is a handwritten character input area, 1903 is a typed character input area, 1904 is an input code list area, 1905 is a scroll bar capable of displaying a plurality of character codes, Reference numerals 1906 to 1909 denote function call buttons by pen taps. Reference numeral 1910 is a recognition candidate display column for displaying candidates of the result of recognizing the pattern written in the handwriting column 1902 by pressing the function call button 1909 (recognition button).

When the "character registration" 2104 of FIG. 21 is instructed in the user dictionary editing unit 103, the branch 507 of FIG. 5 is selected, the control moves to step 1101 of FIG. 11, and the screen shown in FIG. Create a skeleton of and display it in the form of a popup window. The character registration referred to here is an operation of assigning character data by a user's own handwriting to a corresponding character code. Therefore, a data input unit for acquiring the user's handwriting data and a corresponding character code input unit are required. A “handwriting” column 1902 in FIG. 19 is a handwriting data input unit, and a “printing” column 190
3 is a character code input section. Reference numeral 1904 in the lower center of FIG. 19 is an input code list for inputting this character code, and a method of inputting by selecting a character from this is adopted.

Therefore, the character types that can be registered must be displayed in the input code list, but this can be done by creating a character type file in which the character types that can be registered are stored in advance. In step 1102, the character types that can be registered are displayed by reading the character type file. When this display ends, in step 1103,
Wait for a command from the user. "Handwriting" in Figure 19
When the user's pen-down input signal to the column 1902 is detected, the branch 1104 in FIG. 11 is selected, and the handwriting data is stored in the buffer area as a set of two-dimensional coordinate points in step 1201 in FIG. At the same time, it is drawn in the "handwriting" column 1902.

FIG. 19 shows a state in which the user has entered the handwritten abbreviation for "job", and the character code corresponding to this character must be selected from the input code list as described above. By this, the branch 1105 is selected, and in step 1301 of FIG. 13, the character code is once stored in the buffer area, and the character code is acquired. The character selected in step 1302 is enlarged and displayed in the "print" column each time.

"Register" button command 1906 in FIG.
Is selected, the branch 1106 is selected, and in step 1401 of FIG. 14, it is confirmed whether both the handwritten character in the “handwriting” column 1902 and the character in the “printing” column 1903 are input, and the input is made. If so, in step 1403 the creation of a recognition dictionary for that character is started. The recognition dictionary is created by creating a standard pattern from character data, which uses a known technique. As a result, this standard pattern is newly created or added to the user dictionary 1404. If the handwriting data and the character code are not sufficiently input, a warning is issued in step 1402, and the processing is repeated so that the handwritten character data of the character to be registered and the character code are both input.

"Cancel" button command 1907 in FIG.
11 is selected, and in step 1501 of FIG. 15, the character data and character code entered in the “handwriting” column 1902 and the “printing” column 1903 are invalidated. , Move to step 1103,
Allow input again. When the "end" button command 1908 of FIG. 19 is designated, the branch 1109 is selected,
The current new character registration window is erased and control is returned to the user dictionary editing unit 103.

"Recognize" button command 1909 in FIG.
When the instruction is given, and the recognition candidate display field 1 in FIG.
The operation in the case where a candidate is selected from 910 is an important part of this embodiment, and therefore, FIG.
The flow will be described. In FIG. 20, the character “work” is selected from the character recognition candidate display field 1901 and input.

(Handwritten character reproduction unit) Handwritten character reproduction unit 1
The flow of processing in 05 will be described with reference to the flowchart of FIG. 16 and FIG.

In FIG. 22, 2201 is a handwritten character reproduction area, 2202 is a type display area for handwritten characters, 2203 is a handwriting stroke number display area for handwritten characters, and 22
Reference numeral 04 is a standard stroke number display area for the target characters, 2205 and 22.
Reference numeral 06 is a function call button by a pen tap.

When the "handwriting reproduction" 2106 in FIG. 21 is instructed by the user dictionary editing unit 103, the branch 509 in FIG. 5 is selected, and when the character is selected in step 901 in FIG. 9, FIG. 22. The skeleton of the screen shown in FIG. 22 is created by steps 1601 and 1602 of 1. and displayed in the form of a popup window. Since it has been confirmed that the character code is selected in the user dictionary editing unit 103, in step 1603, the character is first displayed in an enlarged font in the print area. Step 1
In 603, the number of strokes of the character is displayed together with the font display. This is performed by preparing a character standard stroke number database in which the standard stroke number is described for each character and searching for the corresponding character.

In order to reproduce the character data in the user dictionary, first, it is necessary to uniquely extract the data in the dictionary corresponding to the character selected in step 1604, but the above-mentioned character code correspondence table is used. It is possible if you do. Since the dictionary data of the corresponding character includes the coordinate point and the pen down and pen up information is added to this, it is possible to determine which stroke number of the handwriting (called a stroke) the coordinate point belongs to. Using this, in step 1604, the handwriting is drawn by successively connecting the coordinate points within the same stroke with a straight line. In step 1605, the number of pen downs is counted as the stroke number of the handwriting data, and this is displayed. In step 1606, if the operation of the button command is "redisplay" 2206, the reproduced drawing data is erased, the process returns to step 1604, and the handwriting reproduction is started again using the data in the dictionary.
If "end" 2206 is designated in step 1606, the current handwritten character reproduction window is erased and control is returned to the registered character editing unit 103.

FIG. 22 is a diagram showing that the character "A" is selected and the character handwriting is reproduced halfway.

(Recognition Candidate Output Unit) Next, the operation of the recognition candidate output unit 107 shown in FIG. 1 will be described with reference to FIGS. 19 and 20 and the process flow charts 11, 25 and 26.

1, the handwriting data stored in the process of branch 1104 of FIG. 11 is called. Next, the normal recognition engine is operated with the handwriting data acquired in step 2502 as an input. The recognition engine at this time means known online handwriting recognition, and any engine may be used, but in the present embodiment, a recognition engine installed in the same device is used. As a result, step 250
In 3, the candidate character string returned from the engine is displayed in the recognition candidate display area 1910 of FIG.

Next, the user selects the recognition candidate area 1 shown in FIG.
When any of the candidate characters displayed in 901 is tapped with the pen, "Job" 1 in the recognition candidate area 1910 in FIG.
It is displayed in reverse as 910a. At this time, the processing of the candidate selection 1110 of FIG. 11 is executed. That is, the code of the candidate character selected in step 2601 of FIG. 26 is acquired,
In step 2602, the acquired character is output to the type display area in step 1903 of FIG. The result is shown in FIG.

The window creating method and the signal detecting method described in the text can be realized by using existing techniques. Also, although the pen was taken as the pointing device, it is clear that selection and entry can also be performed by operating the mouse.

Further, in the recognition candidate output unit of the first embodiment, in step 2502 of FIG. 25, the recognition engine used in the same apparatus is used to output the candidate characters. However, the present invention uses the number of recognition engines. Is not a limitation.
For example, using a radical search and recognition engine that inputs a radical pattern and outputs all Kanji codes that have radicals in the input pattern, recognizes all codes of the radical that are output. It can also be a candidate character. Further, it is possible to display all the candidate characters that have come out as recognition candidates by using both the radical search recognition engine and the ordinary recognition engine. That is, it is possible to easily use a plurality of recognition engines. Figure 2
7 shows how to use the recognition engine of the first embodiment. FIG. 28 shows how to use the plurality of recognition engines according to the second embodiment.

The use of a plurality of recognition engines according to the second embodiment will be briefly described below. The recognition candidate output unit 107 shown in FIGS. 27 and 28 is the same as the recognition candidate output unit 107 shown in FIG. Reference numeral 2701 in FIG. 27 is a pattern for registration input by handwriting. 2703 is a recognition engine used in the same device as that described in the first embodiment. 2702 shows the code information of the candidate character string returned from the recognition engine in an easily understandable manner. 2801 to 2803 in FIG. 28 are the above-mentioned 2701.
To 2703 are exactly the same. 2805 is a second recognition engine, and in this case, a radical search recognition engine. Reference numeral 2804 shows the code information of the candidate character string in which all the characters of the string returned from the second recognition engine 2805 are collected in an easy-to-understand manner. As described above, in the recognition candidate output unit 107 of FIG. 28, a plurality of recognition engines 2803,
2805 is used to obtain and output a recognition candidate sequence.

The present invention may be applied to a system composed of a plurality of devices or an apparatus composed of a single device. Further, it goes without saying that the present invention can be applied to the case where it is achieved by supplying a program to a system or an apparatus.
