2. Description of the Related Art A handwritten character processing device such as a tablet device or an OCR (optical character reading device) mainly plays a role as a data input terminal device for a computer such as a computer or a word processor. By inputting as a handwritten character pattern and performing pattern matching with a standard character pattern prepared in advance, the most similar standard pattern was specified and the character code corresponding to the specified standard pattern was obtained. Then, this character code was used so as to be output as input data of a computer or the like connected to the next stage as a recognition result.

[0003]

When printing a postcard using a word processor to which a conventional tablet device is connected as a data input medium, the user must distinguish between characters according to a standard character pattern and characters according to his or her handwriting. There are things I want. In other words, the user wants to print characters with standard character patterns for fixed forms such as postcards' addresses and postal codes, but for personal documents such as communication contents, print with their own handwriting. It is desired that one word processor realizes the proper use of the characters by the standard character pattern and the characters by one's own handwriting according to the desire of the user. However, the handwritten character processing device including the above-mentioned conventional tablet device can print only the document using the standard character pattern according to the JIS code obtained by recognizing the handwritten character, and the warmth written by one's own handwriting. There is a problem in that, if one tries to write the contents of a private document with a certain character, the postcard is once removed from the word processor and is written by using a pen of one's own, which is inconvenient.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a handwritten character processing apparatus which outputs while selecting a character according to a recognition result of an input handwritten character and a handwritten character as desired.

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

FIG. 1 is a diagram for explaining a functional configuration and processing of a handwritten character processing apparatus according to an embodiment of the present invention in accordance with a data flow.

FIG. 2 is a schematic flow chart showing the operation of the handwritten character processing apparatus according to one embodiment of the present invention.

In FIG. 1, the handwritten character processing apparatus comprises an input unit 10, a processing unit 20 and an output unit 30.

In the input section 10, a pen 1 operated by a user when a handwritten character is input, a tablet 2 integrally connected to the pen 1 and a bitmap storage area 3
including. When the operator operates the pen 1 to draw a character on the main surface of the tablet 2, the character is sequentially stored in the bitmap storage area 3 as image data. At this time, the tablet 2 sequentially inputs the pen position on the main surface by the operation of the pen 1 by the electrostatic induction method, and accordingly sequentially derives it while converting it into a two-dimensional XY coordinate signal. By setting the corresponding bit of, the handwritten character drawn by using the pen 1 is sequentially stored in the bitmap storage area 3 while being converted into image data.

The processing unit 20 operates so as to perform pattern recognition of handwritten characters and derive a corresponding character code. Specifically, the processing unit 20 includes the recognition dictionary 4a and the storage area 5, and is configured to include the recognition unit 4 that can access these. The recognition unit 4 reads out the handwritten character pattern developed in the image data in the bitmap storage area 3 as bitmap image data IM, and recognizes it in the recognition dictionary 4
A pattern matching is attempted while accessing a. In the recognition dictionary 4a, a plurality of standard character patterns are stored with corresponding corresponding character codes.
The recognition unit 4 pattern-matches the bitmap image data IM read from the storage area 3 with each of the standard character patterns stored in the recognition dictionary 4a, and meets the pattern matching condition (bitmap image data IM and similarity. The standard character pattern is specified, and the corresponding character code IC is recognized in the dictionary 4a.
It operates like reading from. The character code IC obtained by this pattern matching is stored in the storage area 5 together with the corresponding bitmap image data IM.
The storage area 5 includes data Di (i = 1, 2, 3, ..., N) created based on the bitmap image data IM read from the bitmap storage area 3. Each of the data Di includes a character code Di1, bitmap image data, input stroke information Di2, and a storage address Di3. The character code Di1 is the character code IC recognized by the recognition unit 4, and the bitmap image data and the input stroke information Di2 are the writing order of the bitmap image data IM corresponding to the corresponding character code Di1 and the handwriting input of the data IM. The input stroke information includes, for example, The storage address Di3 is a head address when the corresponding bitmap image data IM is stored in the bitmap storage area 3.

As described above, the processing unit 20 includes the recognition unit 4, and the recognition unit 4 reads the bitmap image data IM from the bitmap storage area 3. And the data IM
For the pattern matching while accessing the recognition dictionary 4a, recognizes the character code IC, and stores the input stroke information, the character code and the storage address as data Di in the storage area 5 based on the bitmap image data IM. The memory shown in FIG.
Recognition and memory operations are performed.

The output unit 30 displays or prints handwritten characters drawn by the operator operating the pen 1 on the tablet 2 or recognition characters corresponding to the character codes recognized by the recognition unit 4 by referring to the recognition dictionary 4a. It is configured to output via a printer (such as a printer). The output unit 30 displays or outputs the bitmap image data and the input stroke information Di2 or the character code Di1 derived by the processing unit 20 based on the recognized character mode signal EXT externally given by the operator as desired. Works like. That is, when the operator wants to output handwritten characters, which is his handwriting, the given bitmap image data and input stroke information D
i2 is read and the handwritten character is displayed on the screen or printed out. On the other hand, when the operator desires to output a recognized character that is a fixed character pattern according to the recognized character code IC, the character code Di1 is read and the fixed (standard) recognized character is developed as a pattern on the screen or paper. Is output.

As described above, the handwritten character processing device derives, as an output result, either the handwritten character or the recognized character designated by the recognized character mode signal EXT given from the outside. Accordingly, it becomes possible to selectively output a handwritten character which is a handwriting of the user or a recognized character which is a standard pattern.

When the output result is confirmed by the input of the recognized character mode signal EXT, the corresponding storage area of the storage area 5 is cleared (initialized). In other words, it is possible to change the data by inputting handwritten characters before it is confirmed.

The handwritten character processing apparatus operates the pen 1 to sequentially input handwritten characters written on the tablet 2, develops the handwritten characters in the bit map storage area 3 and sequentially stores them. I tried to obtain the bitmap image data IM of the handwritten characters
OCR may be provided to read the handwritten characters in advance, and develop the read characters into image data in the bit map storage area 3 to obtain the bit map image data IM.

The recognition section 4 accesses the recognition dictionary 4a based on the bit map image data IM and outputs the corresponding character code IC. However, the recognition dictionary 4a is output based on the bit map image data IM. It is also possible to access and read the corresponding standard character pattern and store it in the storage area 5 in place of the character code Di1. At this time, the output unit 30 outputs one of the handwritten character and the character based on the standard character pattern.

Next, the operation of the handwritten character processing apparatus will be described with reference to FIG. 1 according to the process flow chart of FIG.

The handwritten character processing apparatus uses the step ST in FIG.
In step 1 (abbreviated as ST1 in the figure), handwritten characters are input. Since the operator operates the pen 1 to draw handwritten characters on the tablet 2, this is sequentially captured as XY coordinate data on the main surface of the tablet 2 and converted into image data in the bitmap storage area 3. Be expanded. Next, processing unit 20 performs recognition including storage, recognition, and storage processing in the processing of step ST2. The recognition unit 4 reads the bitmap image data IM from the bitmap storage area 3 and identifies the corresponding standard character pattern while accessing the dictionary 4a. Then, the character code IC corresponding to the specified standard character pattern is obtained.

Thereafter, the processing of step ST3 is executed,
The processing unit 20 obtains the bit map image data IM read from the bit map storage area 3 and the start address when storing in the bit map storage area 3, and the bit map image data IM is converted into the bit map image data and the input stroke information Di2. Data in storage area 5
The top address obtained by being stored in i is stored in the corresponding data Di as the storage address Di3.

Next, in the processing of step ST4, the processing section 20 causes the operator to externally recognize the recognition character mode signal EX.
Based on T, it is determined whether or not the recognition character mode is set.
That is, if the operator wants to output the recognition character,
The processing unit 20 reads out the character code Di1 stored in the data Di of the storage area 5 and derives it to the output unit 30.
The output unit 30 develops the given character code Di1 into a corresponding standard (standard) character pattern and displays or prints out the recognized character on the screen.

On the contrary, if the recognized character mode is not designated by the signal EXT in the processing of step ST4, the processing section 20 reads the bit map image data and the input stroke information Di2 stored in the data Di of the storage area 5, and To the output unit 30. The output unit 30 develops a pattern on a screen or paper based on the supplied bitmap image data and the input stroke information Di2,
Operates to display or print out handwritten characters on the screen.

When the output of the output unit 30 is completed, the process returns to step ST1 again, and the same process is performed for the next handwritten character.

As described above, every time when one character is input as the handwritten character in the input unit 10, the processing unit 20 recognizes the character code Di1 as the recognition result, the bitmap image data regarding the handwritten character, and the input stroke information Di2. 2
One of these two types of data is output based on the type of data obtained based on the recognized character mode signal EXT given by the operator as desired.

[0028]

As described above, according to the present invention, the first output means outputs one of the handwritten character pattern and the fixed character pattern corresponding to the character code specified by the character code specifying means, as desired. Since the data is output, it is possible to easily use the fixed character pattern and the handwritten character pattern input by the operator's personal handwriting according to the user's wishes when the handwritten character is input.

Also, the second input means outputs either the handwritten character pattern or the standard character pattern specified by the character pattern specifying means, as desired, so that the standard character pattern and the handwriting by an individual handwriting are output. There is an effect that it is possible to easily use a character pattern for inputting a call.

According to the above-described effect, the output character pattern of the handwritten character processing device is arbitrarily set to either the handwritten character pattern or the recognized character pattern (standard character pattern or standard character pattern) according to the operator's request. Since the handwritten character processing device is connected as a data input medium, a word processor, a computer or the like has an effect of diversifying input data and improving usability for an operator.
