Abstract

PURPOSE:To decrease the misrecognizing cases of users without deteriorating the working factor of an optical character reader (OCR) by changing the display forms of characters which are may possibly misread based on the recognizing result of the OCR. CONSTITUTION:The display forms are changed via the control of a CRT 340 and based on the deciding result of an optical character decision control part 321 for such characters whose collation rates are under a prescribed level, the characters which have high possibility for hitting with their collation rates set under the prescribed level, and a character having one or more candidate characters having high collation rates respectively. Thus the characters having the deciding ambiguity are displayed in different forms without deciding those characters as unreadable. As a result, a user notices the characters having the deciding ambiguity. Thus it is possible to decreases the overlooking cases of misread characters without deteriorating the working factor of an automatic cash transaction device using an OCR.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an OCR input method in an automated teller machine, and in particular, to reduce missed characters that are read incorrectly without reducing the operating rate of the automated teller machine. The present invention relates to an OCR input method in an automated teller machine that can perform

[Prior art]

When using an optical character reader (hereinafter abbreviated as OCR) as an input means for public money operations in an automated teller machine,
The challenge is for the user to correct the misread characters due to OCR misreading without missing them.

For example, in the apparatus described in Japanese Patent Application Laid-Open No. 61-229186, the results of reading characters on a transfer form, etc., read by OCR are displayed as they are on a display device.

[Problem that the invention seeks to solve]

In the above-mentioned conventional technology, even when there is a character whose determination remains ambiguous or there are other promising candidate characters, the determination result is displayed in a --like manner.

For this reason, when a user unfamiliar with the machine checks for errors in a relatively large number of characters, such as on a transfer form, for example,
There was a problem that reading errors could be overlooked.

In particular, when inputting amounts without redundancy, such as check digits, there is a risk that serious failures may occur if reading errors are overlooked.

In addition, if all characters that are likely to be misjudged are displayed as unjudged in order to reduce oversights, the number of characters that need to be corrected increases, which increases the user's correction time and reduces the device's operating rate. there were.

The purpose of the present invention is to improve such problems, without reducing the operating rate of automatic teller machines using OCR,
An object of the present invention is to provide an OCR input method in an automated teller machine capable of reducing the chance of missing erroneously read characters.

[Means to solve the problem]

In order to achieve the above objects, 1. The OCR input method in the automatic teller machine of the present invention includes means for optically reading characters (optical character reading mechanism), and determining characters from image data input by the optical character reading mechanism. means (optical character determination control unit), and means for displaying the determination result (
The automatic teller machine equipped with a CRT (CRT) includes means (main control unit) for controlling the display format of the CRT based on the above determination result, and determines whether the determination probability of the character is less than or equal to a predetermined value as a result of the above determination.゛Alternatively, if there are other valid candidate characters, based on the data from the optical character determination control unit, the character that is determined to be most likely to be a correct candidate is displayed on the CRT in a format different from other characters. It is distinctive in its display.

[Effect]

In the present invention, for characters whose determination remains ambiguous, the character with the highest probability is displayed in a different display format.

For this reason, the user can reduce the number of missed errors by focusing on characters that remain ambiguous in their determination.

In addition, even if the judgment is ambiguous, it does not become unreadable.
The operating rate of the device is improved by displaying the character with the highest probability and reducing the number of corrections.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 3 is a configuration diagram of an automated teller machine in one embodiment of the present invention.

The automatic teller machine of this embodiment has a slip/card mechanism 31.

Further, the slip/card mechanism 310 and the slip/card control unit 320 handle automatic transactions using the card 300.

In addition, the optical reading mechanism 311 reads the transfer form 301,
The optical character determination control unit 321 determines the read characters.

In addition, the bill depositing and dispensing mechanism 312 and the bill depositing and dispensing control unit 322 deposit and withdraw bills 302, and the coin depositing and dispensing mechanism 3
13 and the coin deposit/withdrawal control unit 323 deposit and withdraw coins 303 .

The main control unit 330 also controls these, and communicates with the user via the CRT 340 and touch panel 341, and communicates with the host device (not shown) via the interface control unit 35.
Communicate via 0.

In particular, as a result of the determination by the optical character determination control unit 321, there are cases where the matching rate does not reach a predetermined level, cases where the matching rate does not reach the predetermined level but is likely to be correct, or other matching rates. It has a function of controlling the CRT 340 to display one or more candidate characters with a high value in a format different from that of other characters.

FIG. 1 is a flowchart showing OCR input in one embodiment of the present invention.

With this configuration, when the card 300 is read by the slip/card mechanism 310 and the identity of the cardholder is confirmed by the PIN entered from the touch panel 341, the optical character reading mechanism 311 reads the pre-filled transfer form. 301 is read (1001), and the character image data is sent to the optical character determination control section 321 for character determination (1002).

In this determination, a comparison with a character dictionary is performed to obtain a matching rate.

As a result, if the matching rate is greater than or equal to the predetermined value (1003),
Furthermore, it is checked whether there are other candidate characters (1004
).

Through these checks, the matching rate is higher than the predetermined value,
If there are no candidate characters, they are normally displayed on the CRT 340 (1007).

Furthermore, characters determined to be undeterminable are reported to the main control unit 330 and displayed in a different format on the CRT 340 (1005).

In addition, if the matching rate does not reach a predetermined level but there is a high possibility of matching, or if there is one or more other candidate characters with a high matching rate, the main control unit 330 is notified and the CRT 340 Displayed in different formats (100
