Abstract

PROBLEM TO BE SOLVED: To provide a character input processor with which character data can be easily prepared while inputting them at such a speed as that at the time taking notes. SOLUTION: When erroneously recognized characters are not inputted again for the recognition of input character, they are preserved in a recognition file as recognized character data including this character (S1-S6), the form of characters is recorded as bit map data parallelly with this preservation, and the bit map data recorded in the recognition file are preserved in a note function file (S7-S10). Thus, data can be inputted at the speed of note function. Afterwards, the characters in the recognition file and the characters in the note function file are comparatively displayed and concerning the erroneously recognized character, correct answer character candidates are displayed by recognizing it again from the bit map data or it is corrected by inputting the correct answer character from a user.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character input processing device for inputting characters from a touch panel type screen using a pen and handling the characters as character data.

[0002]

2. Description of the Related Art From an electronic organizer to a handy type computer, a character input function has been developed which enables a user to write characters on a touch panel type screen with a pen, recognize the characters by software, and treat the characters as character data. It is becoming popular.

However, the recognition rate of handwritten characters is not yet sufficient, and there are erroneous recognitions. For example, there is little problem when writing characters slowly in a square style, but the recognition rate decreases when writing with common abbreviations at such a speed as to make a note in a notebook.

On the other hand, the above-described apparatus having a character recognizing function has a memo function for storing characters and figures almost written with a pen as image data as they are. This memo function does not recognize characters, but can sufficiently store it even if it is written at the normal memo writing speed. However,
Since the image data is stored as image data, the storage capacity of the device memory is greatly consumed.

[0005]

The conventional character input function has the following problems in character recognition.

(1) At a normal memo writing speed, erroneous recognition increases.

(2) The abbreviation corresponds to some typical characters, but does not sufficiently correspond to many abbreviations.

On the other hand, since the memo writing function does not have a character recognition function, it can exhibit the same effect as a memo written on paper.
In order to digitize the data and use it as data, it is necessary to re-input all documents to a word processor or the like.

When an electronic organizer or the like is used, it is desired that the memo document can be directly input as data into a personal computer or the like. However, as described above, the current character recognition function is not sufficient, so if you take notes with this function, the efficiency will be considerably lower than the memo in a normal notebook due to the fixed price of writing speed and correction of misrecognized characters, etc. This makes it very difficult to use.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a character input processing device which enables input at a memo writing speed while facilitating conversion into character data.

[0011]

According to the present invention, an input character is recognized by a character recognition function and stored in a recognition file.
Record the character shape as bitmap data,
Characters were input at the speed of the memo function, ignoring misrecognized characters, and then the user could point out or re-enter the misrecognized characters by comparing the characters in the recognition file with the characters in the bitmap data. And is characterized by the following devices.

In a character input processing device for inputting characters from a touch panel type screen using a pen and recognizing the input characters and saving the data as text data, characters that are erroneously recognized by the character recognition of the input characters are not re-input. In such a case, means for recognizing the input character, including the character, and storing it in a recognition file, and means for recording the shape of the input character stored in the recognition file as bitmap data and storing it in a memo function file And the character data stored in the recognition file and the bitmap data stored in the memo function file are compared and displayed. Is displayed and the character in the recognition file is corrected with the correct character selected from the character candidates or the correct character re-entered. Characterized by comprising a stage.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 and 2 show a character input processing flow showing an embodiment of the present invention.
1 to S10 are shown in FIG. 1, and the processing after S11 is shown in FIG. Hereinafter, each process will be described in detail with reference to FIG.

(S1) Character input: A character is input using a pen into a character input area provided on a screen of a device having a character recognition function such as an electronic organizer or a notebook computer. This screen image example is shown as A in FIG.

(S2) Character Recognition and Screen Display: Characters input to the character input area are recognized using a character recognition function in the same manner as before, and converted and displayed as text data on the screen.

(S3) Misrecognition check: For the character converted and displayed in step S2, it is checked whether or not the recognized character is erroneously recognized based on a judgment input from the user.

(S4) Re-entry of characters: In the case of erroneous character recognition, the user waits for an input to judge whether or not to re-enter a correct character. In this input, when the character is re-input, the erroneously recognized character is deleted from the screen, and the process returns to step S1.

(S5) Storage of recognized characters: If it is determined in step S3 that character recognition has been normally performed, the characters are stored in a recognition file. If the erroneously recognized character is not re-input in the process S4, the erroneously recognized character is stored in the recognition file as it is. The image stored in the recognition file is shown as B in FIG.

(S6) Character input end check ... Process S1
It is checked based on the judgment input from the user whether or not the character input by the processing from S5 to S5 is completed. If not, the process returns to step S1 to wait for a character input.

(S7) Bitmap data recording: processing S
In parallel with the character recognition in the process S2 for character input by No. 1, the shape of the input character is recorded as bitmap data in a bitmap file. In this data, information necessary for character recognition such as the stroke order of the input characters is also recorded. The image stored in the bitmap file is shown as C in FIG.

(S8) Check for erroneous recognition of input characters: It is checked whether or not the input characters were erroneously recognized in step S2 and re-input in step S4.

(S9) Deletion of erroneously recognized character bitmap data: When the erroneously recognized character is deleted again in step S8, the bitmap data and stroke order information of the erroneously recognized character are deleted from the bitmap file. I do.

(S10) Store in memo function file: The bitmap data recorded in the bitmap file and its stroke order information and the like are arranged as memo information in the memo function file of the apparatus in order and stored.

According to the above-described processing, if the erroneously recognized character is not re-input, the character data including the input character is stored in the recognition file.
The corresponding bitmap data is stored in the memo function file.

At this time, the user can correct the erroneously recognized character each time, can continue ignoring the erroneously recognized character, and input characters at the same input speed as the memo function. Can be.

(S11) Comparison between recognized character and bitmap data: The recognized character stored in the recognition file is compared with the bitmap data stored in the memo function file in association with the recognized character and displayed.

(S12) Check for misrecognized characters ... Process S1
For the recognized character and the bitmap data displayed in step 1, the user waits for an input to determine whether there is an erroneously recognized character. If there is no misrecognized character, the character input process ends.

(S13) Misidentified Character Pointing--A check in process S12 waits for the user to point out a misrecognized character.

(S14) Re-recognition of misrecognized characters: Re-recognition of characters using the misrecognized characters of the recognition file and the character information (bitmap data) of the memo function file corresponding to the re-recognized characters, Display suggestions.

(S15) Correct character check ... Processing S14
Wait for the user to indicate the correct character for another candidate character displayed in.

(S16) Selection of correct character: When the correct character is pointed out by the user in step S15, the correct character is selected as an input character, and the process returns to step S12 to determine whether there is a next incorrectly recognized character. Continue checking.

(S17) Re-input of correct character ... Process S15
When the correct character is not pointed out by the user in
When the correct character is not displayed, it waits for the correct character input from the user. The input character is stored as a correct character of the character in the selection and recognition file, and the process returns to step S12 to continue checking whether there is a next incorrectly recognized character.

Therefore, the input characters stored in the recognition file and the memo function file are compared by the processing of steps S11 to S17, and if there is an erroneously recognized character, another candidate character is displayed by pointing out by the user. The erroneously recognized character is corrected by selecting from the other candidate characters or inputting the correct character by the user.

At this time, the user can correct the character that has been input by ignoring the erroneously recognized character in steps S1 to S6 by selecting or re-inputting another candidate character, and the correction becomes easy.

Further, by using bitmap data including stroke order information and the like, the user can be encouraged to correct the stroke order of the user when an incorrect stroke order character input causes erroneous recognition.

Further, by adding a character recognition dictionary for abbreviations by selecting correct characters for bitmap data, the abbreviation recognition function can be improved.

[0037]

As described above, according to the present invention, an input character is recognized by a character recognition function and stored in a recognition file, and the shape of the character is recorded as bitmap data, and erroneously recognized characters are ignored. To input characters at the speed of the memo function and then compare the characters in the recognition file with the characters in the bitmap data, so that the user can point out or re-enter the misrecognized characters. The same speed as that of the conventional memo function can be ensured, and the erroneously recognized character can be corrected by selecting or re-inputting from the character candidates after the character input, and it becomes easy to convert the handwritten character into text data.
