Abstract

PURPOSE:To correctly recognize a handwritten and inputted character without inputting it again. CONSTITUTION:When characters of 'ISHII' in HIRAGANA (cursive from of Japanese syllabary) are inputted by 5 strokes, the five strokes are sectioned into a character segmentation of a prescribed number and a character recognition is performed for every character segmentation. When the character recognition is performed for a second stroke which should be originally recognized as the component of the character which is the same as a first storke as a character with a third stroke, a division instruction symbol (gesture) 51 instructing the division is handwritten and inputted between these second stroke and third stroke. Thus, each stroke composing different characters is divided into different character segmentations. As a result, a character is possible to be recognized as a correct character.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an electronic notebook device,
The present invention relates to a handwriting input display device suitable for use in a portable computer or the like.

[0002]

2. Description of the Related Art Recently, a device such as an electronic notebook device which can input characters by handwriting is becoming popular. Unlike a normal word processor, a device that can input characters by handwriting can input characters by writing them on the board using a pen instead of the keyboard. You can easily enter characters as if you were writing them with a pencil. Compared with the case of using a keyboard, it is not necessary to store the key positions and the like, so that even a beginner can easily input characters.

As described above, in a device capable of handwriting a character, a device having an input frame for inputting a character and a device having no input frame can input a character at an arbitrary position. There is something.

In an apparatus provided with an input frame, the user manually inputs characters one by one in the input frame. This input frame is usually divided into a plurality of areas, and the user inputs one character in each area. Since the input position is limited, the operability will be poor for the user by that amount, but since the area for inputting each character is divided, it is necessary to cut out the input characters one by one. Instead, it is possible to recognize each character relatively accurately.

On the other hand, in a device that does not have an input frame, the user inputs characters by handwriting at an arbitrary position on the input board (tablet). In this case, the character input by handwriting was recognized as a character at a predetermined timing.

That is, when a character is input, the boundary between the input character and the character is determined. Then, each cut out character is recognized as one character, and the recognition result is displayed.

As a result, for example, as shown in FIG. 16 (a), when the user inputs the Chinese character "Akira", the two characters "day" and "month" constitute one character. In the case of being cut out as a character to be processed, the input character is recognized as the Chinese character of "my".

However, as shown in FIG. 16 (b), the characters "day" and "month" are relatively separated from each other, and these characters are cut out as separate characters. In such cases, "day" and "month"
Will be recognized as separate characters.

[0009]

In the conventional device, the result recognized as the characters of "bright" or the result recognized as the characters of "day" and "month" is the user's intention. If it is different, you have to enter it again,
There was a problem that it took time to input the intended characters.

The present invention has been made in view of such a situation, and it is possible to more quickly input a desired character, figure, or the like.

[0011]

A handwriting input display device according to the present invention includes an input means for handwriting a handwriting (for example, the pen 16 in FIG. 1) and a recognition means for recognizing the handwriting input by the input means (for example, a drawing). Step S on program 2
1), a display unit (for example, the display unit 13 in FIG. 1) for displaying the handwriting input by the input unit, and the recognition result obtained by the recognition unit, and a combination of a plurality of handwriting when recognizing the handwriting. It is characterized by including a changing means (for example, the division instruction symbol 51 in FIG. 4) for changing.

This device is further provided with a selection means (for example, a candidate order display unit 61 in FIG. 8) for selecting a predetermined one of the displayed recognition results when displaying a plurality of recognition results on the display unit 13. be able to.

[0013]

In the handwriting input display device having the above construction, when a predetermined handwriting is input, the recognition result obtained by recognizing the handwriting is displayed. Then, when the displayed recognition result is different from the intended result, a combination of a plurality of input and displayed handwritings can be divided or combined by inputting a predetermined gesture. Therefore,
It is possible to input the intended character without inputting new handwriting again.

[0014]

FIG. 1 is a block diagram showing the configuration of an embodiment of a handwriting input display device of the present invention. CPU1 is RO
Each unit is controlled according to the program stored in M2 to execute the character input display operation.
The RAM 3 stores predetermined data and the like as needed. The backup RAM 4 is always supplied with a predetermined amount of power from the battery 5, and stores the information to be stored even when the power of the apparatus is turned off. The timer 6 is always operated by the battery 5 based on the crystal oscillator 7.

The display controller 11 expands the data input via the bus line 8 into the V-RAM 12, and displays the expanded image on the display unit 13. The input tablet 15 is
By operating the pen 16, the input coordinate position data is output to the tablet interface 14, and the tablet interface 14 outputs this data to the bus line 8.
Via the CPU 1 or the display controller 1
It is designed to output to 1.

The microphone 18 outputs the collected audio signal to the solid-state recording processing circuit 17 and stores it. The audio signal output by the solid-state recording processing circuit 17 is supplied to the speaker 21 via the adder 20 and emitted. Dialer 19 is CPU1
And outputs a predetermined dial signal to the speaker 21 via the adder 20.

The plurality of key switch groups 22 are operated when switching the operation of the apparatus, and a signal corresponding to the operation is sent from the key interface 23 to the CP via the bus line 8.
It is designed to be output to U1. Further, by operating a predetermined one of the plurality of key switch groups 24, the power supply circuit 25 is turned on to supply electric power to each unit, and recording, reproduction, stop by the solid-state recording processing circuit 17,
It is designed to be able to perform volume adjustment and so on.

Further, the socket 26 has an IC (not shown).
It is designed so that a card can be inserted.
The C card interface 27 is designed to send and receive data to and from this IC card.

A modem, for example, can be connected to the pin connector 29, and signals can be exchanged with the extension interface 28 via this modem.

The input tablet 15 is made of a transparent material and is formed on the display unit 13. As a result, the display on the display unit 13 can be seen through the input tablet 15.

Next, referring to the flowchart of FIG.
The operation when handwriting a character will be described. When a character is handwritten on the input tablet 15 with the pen 16, the handwriting data is supplied to the handwriting handwriting database DB1 of the RAM 3 via the tablet interface 14 and stored therein. Further, the handwriting data is supplied to the V-RAM 12 by the display controller 11 and developed as bit map data. This bitmap data is displayed on the display controller 11
Is read out, and is output and displayed on the display unit 13. As a result, the pen 1 is displayed on the display unit 13.
The handwriting input in 6 will be displayed.

In step S1, the CPU 1 thus reads the handwriting data stored in the handwriting handwriting database DB1 and executes the character recognition process. The data obtained as a result of the recognition is supplied to and stored in the recognition result database DB2.

Next, in step S2, of the recognition results stored in the recognition result database DB2, the first recognition result having the highest score (high similarity) is read out and displayed on the display unit 13. To be done.

FIG. 3 schematically shows the above operation. That is, if the character "Ishii" in Hiragana is input, the handwriting data of this character is subjected to character recognition processing, and in this embodiment, three candidates are obtained.

That is, the character "Ishii" in hiragana is composed of five strokes, but in the first candidate, the five strokes are divided into four character segmentations. The first stroke constitutes one character segmentation, which is recognized as the hiragana "shi". Then, one character segmentation is composed of the second stroke and the third stroke, and in this embodiment, it is recognized as the katakana "ru". Furthermore, the 4th stroke and the 5th stroke are recognized as different character segmentations, the 4th stroke is the number "1", and the 5th stroke is ")".
Is recognized as

On the other hand, in the second candidate, like the first candidate, five strokes are divided into four character segmentations. The first character segmentation is composed of the first stroke and the second stroke and is recognized as the hiragana "i". The second character segmentation is composed of the third stroke and is recognized as the hiragana "shi". Furthermore, the 3rd and 4th character segmentation is comprised by the 4th stroke and the 5th stroke, respectively, and is recognized as a number "1" and a symbol ")" like the case in the 1st stroke.

Furthermore, in the third candidate, 5 strokes are divided into 3 character segmentations. The first character segmentation is composed of the first stroke and the second stroke and is recognized as the hiragana "i". The second character segmentation is composed of the third stroke and is recognized as the hiragana "shi". Further, the third character segmentation is composed of the fourth stroke and the fifth stroke and is recognized as the hiragana "i".

In the case of this embodiment, among the above three candidates, the input handwriting and the first character recognition result are obtained.
The th candidate is displayed on the display unit 13.

The recognition result is information on character segmentation (for example, coordinates of a rectangle circumscribing a handwriting (circumscribing rectangle), image data of a character, etc.), a character code corresponding to the recognition result, and It has a similarity (score) to the character represented by the character code.

Although it is not necessary to display the circumscribed quadrangle for each character segmentation, displaying it makes it easier to input the correction of the character segmentation described later.

Returning to FIG. 2, after step S2, the process proceeds to step S3 to receive new input from the user. Then, in step S4, it is determined whether or not the input received in step S3 is an instruction to modify the character segmentation. When the input handwriting does not instruct the correction of the character segmentation, the processing ends. If the input received in step S3 is an instruction to modify the character segmentation, the process proceeds to step S5 to further obtain a recognition result that matches the modification instruction.

That is, the CPU 1 accesses the recognition result database DB2, and performs the recognition process again according to the character segmentation correction instruction instructed by the user in step S3. Then, the recognition result obtained by the correction is supplied to and stored in the correction recognition result database DB3.

The correction of character segmentation is performed as shown in FIGS. 4 and 5, for example.

In the embodiment of FIG. 4, as a result of the processing in step S2, the first candidate is displayed as the character recognition result together with the handwriting. The user entered the character "Ishii" in hiragana, but among these handwritings, the first and second strokes that make up the character "i" were not recognized as one character. The second stroke is recognized as forming a character with the third stroke (“shi”) that should be recognized as an independent single character. Therefore, as shown in FIG. 4, the user inputs a substantially V-shaped division instruction symbol (gesture) 51 instructing to divide the character segmentation composed of the second stroke and the third stroke.

Upon receiving the input of the division instruction symbol 51, the CPU 1 divides one character segmentation composed of the second stroke and the third stroke into two character segmentations. That is, the second stroke and the third stroke are re-executed as the handwriting that constitutes different characters.

In the embodiment of FIG. 5, originally, the fourth stroke and the fifth stroke which should form one character are different character segmentations, so these two character segmentations are combined as one character segmentation. 4 shows a state in which a combination instruction symbol (gesture) 52 for is input. The combining instruction symbol 52 is a symbol in which a substantially V-shaped symbol is laid sideways so as to cross each of the plurality of character segmentations to be combined. When such an input is made, the CPU 1 processes a plurality of character segmentations spanning this combination instruction symbol 52 as one character segmentation.

FIG. 6 shows details of the processing for re-obtaining the recognition result that matches the correction instruction in step S5 in FIG. As shown in the figure, first in step S31, it is determined whether or not the inputted character segmentation correction instruction is an instruction for segmentation combination. In this example, the modification of character segmentation is either splitting or joining.

When the input is not an instruction to combine the character segmentations, that is, an instruction to divide the character segmentation (see FIG. 4).
When the division instruction symbol 51 as shown in (4) is input), the process proceeds to step S35, and the division position of the segmentation to be divided is obtained from the coordinate value of the circumscribed rectangle of the handwriting of the division instruction symbol (division instruction gesture) 51.

In the case of the embodiment of FIG. 4, the character segmentation that intersects the circumscribed rectangle of the division indicator 51 is the second.
Since it is the second character segmentation, this is selected as the character segmentation to be divided. Since the division instruction symbol 51 is positioned between the second and third strokes, the space between the second stroke and the third stroke is determined as the division position.

Next, in step S36, a result string having segmentation before and after the segmentation division position obtained in step S35 is obtained from the recognition result database DB2. That is, in the case of this embodiment, since the handwritings of the second stroke and the third stroke are processed as constituting different characters (character segmentation), the handwritings of the first stroke and the second stroke are processed. Recognized as one letter "i". Also, the third stroke is recognized as one character "shi".

Further proceeding to step S37, step S
The result obtained in 36 is the recognition result database D for correction.
It is supplied to B3 and stored. That is, the third in FIG.
The candidates are stored in the correction recognition result database DB3.

On the other hand, if it is determined in step S31 that the input gesture is the combination instruction symbol 52 for instructing combination, the process proceeds to step S32. From the coordinate values of the circumscribed quadrangle of the handwriting, the set of segmentation to be combined is obtained.

In the case of the embodiment shown in FIG. 5, since the combination instruction symbol 52 is input over the character segmentations each composed of the fourth stroke and the fifth stroke, these character segmentations are regarded as one character segmentation. Selected as the character segmentation to be processed.

Then, the process proceeds to step S33, and a result string including a result in which the character segmentation set obtained in step S32 becomes one character segmentation is obtained from the recognition result database DB2. In the case of the embodiment of FIG. 5, the character “i” obtained by recognizing the fourth stroke and the fifth stroke as one character is obtained.

Further proceeding to step S34, step S
The result obtained in 33 is the recognition result database for correction DB3
Supply and store. In the case of the embodiment shown in FIG. 5, the character "i"
Will be stored in the correction recognition result database DB3.

In the case where there are a plurality of recognized results after the processing of collecting the recognition results matching the correction instruction in step S5 in FIG. 2 is performed as described above, the processing proceeds from step S5 to step S6 and subsequent steps. , A predetermined one of them is displayed.

In step S6, the internal variable j is initialized to 1. Then, in step S7, the j-th recognition result is displayed on the display unit 13. That is, CP
U1 is the first (j = 1) of the data stored in step S5 from the correction recognition result database DB3.
The data is read, output to the display unit 13, and displayed. Next, in step S8, a new input from the user is received. Then, in step S9, step S
It is determined whether or not the handwriting received in 8 instructs to display the next candidate. If it is not the next candidate display instruction, the process further proceeds to step S13, and it is determined whether or not it is an instruction to display the previous candidate.

If it is determined in step S9 that it is the next candidate display instruction, the process proceeds to step S10, the variable j is incremented by 1, and the process proceeds to step S11. Step S
In 11, it is determined whether or not the variable j incremented in step S10 is larger than the number of candidates stored in the correction recognition result database DB3.
If it is determined that the variable j has a value less than or equal to the number of stored candidates, it means that there are still candidates to be displayed next, so the process returns to step S7 and corresponds to the variable j incremented in step S10. Display the recognition result.
That is, the next candidate is displayed.

On the other hand, when it is determined in step S11 that the variable j has become larger than the number of candidates stored in the correction recognition result database DB3, that is, when the last candidate has already been displayed. , Go to step S12, set the variable j to 1, return to step S7, 1
Display the th recognition result. That is, the display of the candidate of the recognition result is sequentially changed to the next candidate, and when the last candidate is reached, the display returns to the first candidate.

On the other hand, when it is determined in step S13 that the handwriting input in step S8 is an instruction to display the previous candidate, the process proceeds to step S14, and the variable j is decremented by 1. And step S15
When it is determined that the variable j is 1 or more, the previous candidate still remains as a recognition candidate, and thus the process returns to step S7 and the recognition result corresponding to the variable j decremented in step S14 is displayed. That is, the previous recognition candidate is displayed.

If it is determined in step S15 that the variable j has become smaller than 1, it means that there is no candidate earlier than this because the displayed result is the first recognition result. Therefore, in this case, the process proceeds to step S16, and the variable j is set to a value equal to the number of correction database candidates. That is, the last candidate is selected, the process returns to step S7, and this is displayed.

In this way, the candidate to be displayed is sequentially changed to the previous candidate, and when the first candidate is reached, the display is changed to the last candidate.

In step S13, when it is determined that the handwriting received in step S8 does not instruct the display of the previous candidate, the process returns to step S3, waits for a new input again, and corresponds to the handwriting. Will be processed.

As described above, steps S6 to S1
In 6, when there are a plurality of recognition candidates, any one of them can be sequentially selected and displayed.

The above step S3 or step S
The input (command) in 8 is the gesture 16 and the pen 16
Alternatively, the operation can be performed by operating a predetermined position on the input tablet 15. Alternatively, it is also possible to input with a mouse or a keyboard.

In this way, any one of the first to third candidates shown in FIG. 3 is sequentially displayed.

The above processing is summarized as shown in FIG. That is, as shown in FIG. 9A, when the character “Ishii” is input by handwriting, the handwriting is displayed. When the input handwriting is recognized, the first candidate of the recognition result is displayed at the lower right of the handwriting, as shown in FIG. The user can see this recognition result and know that the second stroke and the third stroke, which should be recognized as different characters, are included in one character segmentation.

Then, the user inputs a division instruction symbol 51 for dividing the second character segmentation into two character segmentations. as a result,
As shown in FIG. 7C, one character "i" is recognized and displayed by the first and second strokes, and one character "shi" is recognized and displayed by the third stroke.

Furthermore, since the fourth stroke and the fifth stroke which should be recognized as one character have been recognized as different character segmentations, if a combining instruction symbol 52 for connecting them is input, the same figure (d) is displayed. ), The character “i” obtained as a result of recognizing the fourth stroke and the fifth stroke as one character is displayed.

As described above, after inputting a character once by handwriting, by referring to the recognition result as necessary, by inputting an instruction for dividing or combining character segmentation, without rewriting the character, It is possible to recognize the originally intended character.

FIG. 8 shows another display example. In this embodiment, as shown in (a) of the figure, when a character of "various" is input, the handwriting is displayed. Then, character segmentation is cut out from this handwriting, and character recognition is performed for each character segmentation. Then, as shown in FIG. 6B, a circumscribed quadrangle indicating the character segmentation is displayed. In the case of this embodiment, the first stroke to the sixth stroke are respectively classified as different character segmentations A to F.

Further, FIG. 8C shows a state in which a plurality of results (four sets in the case of this embodiment) of recognizing the respective character segmentations A to F are displayed. When a predetermined set is selected from the displayed plurality of sets, the candidate rank display section 6 displayed on the leftmost side is selected.
The corresponding one of 1 is touched with the pen 16. Thereby, the touched combination is selected as the recognition result.

Further, in this embodiment, the scroll bar 62 is displayed on the rightmost side, and the scroll bar 62 on the uppermost side or the triangular display portion 62b on the lowermost side is drawn by the pen. By touching with 16, when there are 5 or more sets of displayed candidates, the display state can be scrolled up and down. If the display unit 62a is touched, the candidates are scrolled upward, and if the display unit 62b is touched, the candidates are scrolled downward.

FIG. 9 shows another display example.
In this embodiment, as shown in FIG.
When the strokes to the sixth stroke are input, the handwriting is displayed. Then, the character segmentation corresponding to the first-ranked recognition candidate is displayed as shown in FIG. Further, as shown in FIG. 7C, a plurality of candidates for a plurality of character segmentations are displayed simultaneously (4 sets in this embodiment).

Also in this case, the candidate ranking display section 61
A predetermined recognition result can be selected by touching a predetermined object with the pen 16 and the display unit 62a.
Alternatively, the display of the candidates can be scrolled by operating the display unit 62b, as in the case of FIG.

FIG. 10 shows another display example. In this embodiment, as shown in FIG.
In the state in which a plurality of recognition results are displayed, the front candidate display instruction gesture 71 is input by handwriting with the pen 16 as shown in FIG. 7B, or the next candidate is displayed as shown in FIG. By handwriting the display instruction gesture 72 with the pen 16, the recognition candidates can be scrolled upward or downward, respectively. In the case of this embodiment, the previous candidate display instruction gesture 71 and the next candidate display instruction gesture 72 are in the shape of a triangle that faces upward or downward.

Further, in the case of this embodiment, instead of inputting the previous candidate display instruction gesture 71 or the next candidate display instruction gesture 72, the display portion 62 of the scroll bar 62.
The display can be similarly scrolled by touching a and 62b with the pen 16.

FIG. 11 shows a handwritten handwriting database DB1.
Shows an example of the format. As shown in the figure,
The image number is arranged first, and then the number n of coordinate points of the image corresponding to the image number is arranged. Then, after that, the coordinate values (x ₀ , y ₀ ), (x ₁ ,
y ₁ ), ..., (x _n-1 , y _n-1 ) are arranged.
Similarly, when a plurality of images are input, the numbers of the images, the number of coordinate points, and the coordinate values are sequentially arranged. Finally, the end-of-file symbol is placed.

FIG. 12 shows an example of the format of the recognition result database DB2 and the correction recognition result database DB3. First, the recognition results corresponding to each character segmentation are sequentially arranged. In the recognition result for each character segmentation, the ID of the character segmentation is placed at the beginning, and then the start image number and the end image number of the character segmentation are placed. Then, the coordinates (x ₀ , y ₀ ) of the diagonal vertices of the circumscribed rectangle of the character segmentation,
(X ₁ , y ₁ ) are arranged. Further, the number N of recognition candidates is arranged next to the character code and the character codes and grade values of the first to Nth recognition candidates are arranged.

At the end of the recognition result for the one-character segmentation, a recognition result end code for the one-character segmentation is arranged. And then,
The character segmentation forming the character recognition result obtained by combining the character segmentation so that the grade value becomes high is sequentially arranged. The character recognition result is composed of a candidate ID, the number M of character segmentations forming the candidate, and the ID (ID _{0 to} ID _M ) of the character segmentation. And the file end code is added at the very end.

In the above description, the case of inputting characters by handwriting has been described as an example, but the present invention can also be applied to the case of inputting graphics.

13 and 14 show an embodiment in this case. FIG. 13A shows a state in which, as in the case of drawing an electric block diagram, three quadrangles and a line segment connecting the quadrangles are input and the handwriting is displayed. The figure (b) further displays the result of recognition of the handwriting shown in the figure (a), and also the figure segmentation of each figure.

In the case of this embodiment, the input figure is 5
It is divided into two graphic segmentations, but the second
The second figure segmentation is segmented including the line segments that should originally form the first figure. Therefore, as shown in FIG. 7B, the division instruction symbol 51 is placed at a predetermined position.
If you enter, as shown in FIG.
The line segment included in the th figure segmentation is
Modified to be included in the first graphic segmentation.

By the above processing, the figure segmentation is divided into the quadrangle and the line segment connecting the quadrangle.
Although the processing may be terminated by this, a plurality of graphic segments among them can be further combined into one graphic segment.

In this case, as shown in FIG.
The combination instruction symbol 52 is input so as to extend over the graphic segmentation (in the present embodiment, the third to fifth graphic segmentation) to be put together.
As a result, as shown in FIG. 14B, these third to fifth graphic segmentations are combined into one segmentation.

The graphics grouped in one graphic segmentation are, for example, transferred, deleted, etc.
The process is performed as a whole.

As described above, even in the case of inputting a figure, when there are a plurality of recognition candidates, desired candidates can be displayed one by one. FIG. 15 shows this embodiment. That is, in FIG. 15A, one input handwriting and one recognition result corresponding thereto are displayed. A plurality of the recognition results can be displayed at the same time as in the case shown in FIG.

Then, as shown in FIG. 15B or 15C, by inputting the previous candidate display instruction gesture 71 or the next candidate display instruction gesture 72, the recognition result to be displayed is scrolled to the previous candidate or the next candidate. Can be allowed to.

As described above, the present invention can be applied to the case of displaying arbitrary shapes such as characters and figures.
