Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a real-time kanji recognition device that recognizes and processes kanji handwritten on an input tablet in real time. To provide a character input device suitable for re-inputting characters when the characters are unreadable or erroneously read.

<Background of the invention> For example, in the case of a conventional kanji recognition device, when a kanji input by handwriting becomes unreadable due to the personality of the person writing it, multiple candidate characters are displayed on the CRT screen during the recognition process. A method is adopted in which the person filling out the form selects one of the candidate characters and re-enters it. However, with this method,
The candidate characters may not include the character intended by the person writing the information, and in such a case, it becomes difficult to select from the candidate characters. In addition, when input characters are misread, there is no motivation for candidate characters to be picked up, so the user abandons inputting handwritten characters and enters kana characters by operating keys on the keyboard of the target system. Using the kana and kanji conversion processing function that I have, I re-enter the intended kanji.

<Object of the Invention> The present invention provides a character input device for a real-time kanji recognition device, which re-inputs the intended kanji using kana characters into an input tablet when handwritten characters are misread or unreadable. The purpose is to provide equipment.

<Configuration and Effects of the Invention> -1- In order to achieve ease of distribution, the present invention provides a character entry area and a touch key area on the input tablet, and also converts kana character input into kanji in the touch key area. A touch key is provided for inputting commands, and when the person who enters the touch key operates the touch key and writes the sound or precept of the kanji that he/she wants to input in the character entry area in kana characters, the handwriting and key type are displayed. , and sends a command for kana/kanji conversion processing to the target system, and the target system also executes processing to convert input kana characters into kanji.

According to the present invention, even if a handwritten kanji is illegible or misread, the intended kanji can be re-entered properly and quickly by writing the sound or precept of the kanji in kana characters on the input tablet. . In addition, since the kana/kanji conversion function of the target system is effectively utilized, the device is extremely easy to configure, and has the remarkable effect of achieving the purpose of the invention.

<Description of Embodiments> FIG. 1 shows an example of the configuration of a real-time kanji recognition device according to the present invention, in which a character input device 3 consisting of an input tablet 1 and a control section 2 is connected to a control body of a target system by a connection cord 4. It is electrically connected to section 5. The control main body section 5 has a keyboard 6 and a CRT display section 7 on the front side of the body, and a control processing circuit consisting of a computer circuit is incorporated inside the body. This control processing circuit is provided with the function of converting kana characters into kanji when the keys are pressed manually from the keyboard 6, and the characters input manually from the keys, the kanji to be converted, and even the handwritten characters input from the input tablet 1 are converted into kanji. , is displayed on the CRT display section 7.

The input tablet 1 includes a dedicated input pen (not shown).
This is for inputting predetermined characters or commands by touching or moving the pen tip to the board surface, and there is a character entry area 9 and a touch key area within the sensing area 8 where the touch of the pen tip can be detected. 10 is divided and formed. The character entry area is provided with a plurality of rectangular character entry frames 11 in the vertical and horizontal directions, while the touch key area 10 is provided with a plurality of touch keys 12 having various functions. This group of touch keys includes touch keys 12AC for inputting commands to instruct the target system to perform kana/kanji conversion processing.
When inputting kana characters by hand in the character entry area 9, if you touch and operate this conversion key 12A with the pen tip, the target system will convert the input kana characters into corresponding characters. It functions to convert the kanji into kanji.

FIG. 2 shows an example of the circuit configuration of the control section 2. The illustrated control section 2 includes a coordinate value detection circuit 13, a pen touch detection circuit 14, a pen-off detection circuit 15, a coordinate code generation circuit 16, and a character entry circuit. It includes a region common control circuit 18, a control code generation circuit 19, and an interface circuit 20.

The coordinate value detection circuit 13 is composed of a matrix circuit, and detects the X and Y coordinates of the pen tip that is in contact with the sensing area 8 . The pen-touch detection circuit 14 detects that the pen tip of the input pen touches the sensing area 8, while the pen-off detection circuit 15 detects that the pen tip leaves the sensing area 8. The character writing area common control circuit 18 determines whether the pen tip of the input pen has touched the character writing area 9 based on the output data of the coordinate value detection circuit 13. The coordinate code generation circuit 17 starts operating under the condition of merging the detection output of the pen touch detection circuit 14 and the discrimination output of the character writing area common control circuit 18, and converts the handwriting coordinate information of the input pen into, for example (
538, 204) and output to the target system through the interface circuit 20. Note that the circuit operation of the coordinate code generation circuit 17 is stopped by the detection output of the pen-off detection circuit 15. The control code generating circuit 9 starts operating when there is no detection output from the character entry area common control circuit 18 and there is a detection output from the touch key detection circuit 14. In this case, the touch key area 10 Since this is an input to a target system, a control code corresponding to the function of the inputted touch key is generated and sent to the target system via the interface circuit 20.

FIG. 3 shows the control operation of the above device example.

When kanji are input by hand into the character entry area 9 of the intervention power tablet 1, the handwriting of the input characters is encoded into coordinate information by the coordinate code generation circuit 17 and then sent to the target system for feature extraction, dictionary comparison, etc. A series of character recognition processes are executed. If a handwritten input character cannot be recognized, a message to that effect will appear on the CRT display section 7, and if a character is misread, the misread character will be displayed on the This allows the user to recognize misreading or unreading (step 21).Here, the user inputs the intended kanji by hand again into the input tablet 1, or inputs the 1l11 or sound of the kanji in kana characters. If you choose the former method and the kanji you need to re-enter is correctly recognized, select "Re-enter?" in step 22. Judgment and Step 23 “Is it a direct continuation?
'' are both ``YES'', and the process moves to the next character entry operation (step 24).

On the other hand, when adopting the latter method using kana human power, the determination in step 22 is "NO", and in this case, the conversion key 12A of the touch key area 10 is used before or after inputting characters into the character entry area 9. Touch and operate with the pen tip (
Step 25). As a result, the control code generation circuit 19 determines that the touched key is the conversion key 12A, and sends a command to instruct the function of the conversion key 12A, that is, kana/kanji conversion processing, via the interface circuit 20. It is sent to the target system (step 26, '27).

Then, the target system that received this command recognized the kana character from the handwriting strength of the input character input from the coordinate code generation circuit 17 via the interface circuit 20. Process the conversion into
The processing results are displayed on the CRT display section 7 of the control main body section 5.

In this way, all characters are handwritten into the input tablet 1 using the same procedure, and finally the touch key area 10
When you operate the character input end touch key (not shown),
The determination in step 29 becomes 'YES', and all processing operations are completed.
