Abstract

PURPOSE:To execute KANJI (Chinese character) input by KATAKANA (Japanese syllabary) character by having the function to convert to the KANJI when KATAKANA character is inputted to an optical character recognizing device in accordance with a certain rule. CONSTITUTION:A scanning means 2 scans an original picture 1, cuts out the pattern for respective characters and outputs to a recognizing means 4. The recognizing means 4 recognizes the character pattern inputted from a scanning means, decides whether or not said character is the one for which the KATAKANA KANJI converting is required on the slip, and stores the information and a character code obtained as the result into a memory means 4. A control means 5 displays a character image corresponding to the character code in the memory means 4 at a displaying means 8, extracts the KANJI character code of the candidate character corresponding in a dictionary means 6 for the character column 'easily' for which KATAKANA/KANJI converting is required on the slip, and displays the corresponding character image. An operator confirms the character, and when the error does not exist at the display, gives the indication of the confirmation completion through a key input means 7 to the control means.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an optical character reading device (hereinafter referred to as OCR).
Regarding.

[Conventional technology]

Conventionally, this type of QC can only recognize and input characters written on a form.

Therefore, when inputting kanji, the kanji to be entered must be entered correctly on the form.
If the user forgets how to write kanji and is unable to write them in kanji, kanji input will not be possible.

[Problem that the invention seeks to solve]

Therefore, an object of the present invention is to provide an 0CkL that has a function of converting katakana written in accordance with predetermined rules into kanji, and that allows kanji input without writing kanji on a form.
[Means for solving the problem] The optical character reading device of the present invention scans each character on a form with a scanning means and uses a recognition means to extract a character pattern. sends and recognizes the character, stores the code of the character and information as to whether the character is required to be converted into kana-kanji on the form in a storage means, and displays a character image corresponding to the character code. Display it on the means. Here, for characters or continuous character strings for which kana-kanji conversion is requested on the form, a signal requesting kana-kanji conversion is sent from the recognition unit to the control means, and in response, the control means uses the kanji dictionary. In addition to displaying attributes such as inverting the character image corresponding to the arbitrary character code Ruru or character code string of the candidate character from the registered dictionary means, the character code Ruru or character code of the remaining candidate characters can be displayed. Is the character image corresponding to the column a serial number? Add it and display it. The system is characterized in that the operator confirms the correct characters and then indicates the correct characters using the key input means, thereby converting kana to kanji and inputting kanji.

〔Example〕

Next, the present invention will be described in detail with reference to the drawings showing one embodiment of the present invention.

Referring to FIG. 1, when the operator gives an instruction to start reading the original image 1 to the key input means 7 by key input, a reading start instruction signal is transmitted to the control means 5. When the control means 5 receives the signal, it sends a scanning start signal to the scanning means 2. When the scanning means 2 receives the scanning start signal, it photoelectrically converts the original image 1 and performs a character pattern cutting process for each character. When the extraction process is completed for all characters, character patterns are sequentially output to the recognition means 3 for each character. Recognition means 3
is the character pattern i&! At the same time, it is determined whether the character is a character for which a kana-kanji conversion request has been issued on the form, and the resultant information and recognized character code are stored in the storage means 4.

The storage means 4 issues a display request to the control means 5.

The control means 5 accordingly displays a character image corresponding to the character code in the storage means on the display means 8. Here, if this character Rurui or the continuous character string is a kana character for which a kana-kanji conversion request appears on the form, the control means 5 searches the dictionary means 6 to find the kanji corresponding to the character or the continuous character string. Character codes are extracted and character images corresponding to those character codes are displayed on display means 8. Further, serial numbers are added to character images corresponding to the remaining candidate Kanji character codes in the dictionary means 6 and displayed on the display means 8.

When a signal indicating completion of kana-kanji conversion is transmitted from the operator via the key input means 7ft, the character code corresponding to the character image displayed on the display means at that time is stored in the storage means.

Next, the operation of one embodiment of the present invention will be described using specific input data as an example.

The original picture 1 shown in Fig. 2 is written on the form.

The part surrounded by ■ is the character required for kana-kanji conversion 1. The scanning means 2 scans the original image 1, cuts out a pattern for each character, and outputs it to the recognition means 4. Recognition means 4
recognizes the character pattern input from the scanning means, determines whether the character is a character required to be converted into kana-kanji on the form, and stores the information and character code obtained as a result. The information is stored in means 4. The control means 5 causes the display means 8 to display a character image corresponding to the character code in the storage means 4, but the dictionary means 6 displays the character image corresponding to the character code in the storage means 4 for a continuous character string "1" for which kana-kanji conversion is requested on the form. The Kanji character code of the candidate character corresponding to ``1'' is extracted, and the corresponding character image is displayed. At this time, to indicate that the Kana-Kanji conversion content needs to be confirmed, the background and figure of the first candidate character are displayed in reverse, and serial numbers are added to the remaining candidate characters in the dictionary means 6. It is stored in the storage means 4 and displayed on the display means. In this way, a display as shown in FIG. 3 is obtained.

The operator checks the highlighted characters on the background and figure, and if there is no error in the display, gives an instruction to the control means 5 via the key input means 7 to complete the confirmation.

Accordingly, the control means 5 stores the character code corresponding to the currently displayed character image in the storage means.

As shown in Fig. 3, if the highlighted characters in the background and figure are incorrect, the operator selects the correct character from among the candidate characters displayed on the display means 8 and enters the number attached to it. Input from the key input means 7. In the example in Figure 3, the character ``1 Ready'', which is displayed in reverse video, is an error, so we select the correct character from the candidate characters.
Select "Easy" and input the number @1 added thereto using the key input means 7.

The signal is transmitted to the control means 5, and the control means 5 accordingly replaces the character code corresponding to the key-input number in the storage means 4 with the character code of the current location and the highlighted character in the diagram, and converts it into a character code. The corresponding character image is displayed on the display means 8. At this time, the location and figure are not displayed in reverse.

In this way, a display as shown in FIG. 4 is obtained, and the kanji input is completed.

Note that in this example, the characters are surrounded by kana characters ■ to indicate that they require kana-kanji conversion on the form, but the notation is not limited to this type of notation. Various notations can be used, such as surrounding the target character with characters other than the target character.

〔Effect of the invention〕

As described above, the present invention makes it possible to realize 0CRi, which allows kanji input using kana characters, by providing an optical character recognition device with a function of converting kana characters into kanji when input according to certain rules. can.
