Abstract

PURPOSE:To simplify the method of re-inputting for re-recognition and to easily comprehend the re-input of characters at an OCR device. CONSTITUTION:When the data of a sheet 11 are transmitted from a facsimile terminal to a center, OCR characters are reproduced from the transmitted data by a center recognizing device, and data in a step for first inputting are analyzed by a recognition part. Then, the result is transmitted to the facsimile terminal of the transmission source as a confirmation slip 12, for example. In this case, characters having the low certainty of recognition are outputted to the second step. When this is observed and it is judged that re-inputting is required, at the facsimile terminal, only the desired characters to be re- inputted like No.3 (sheet 13) are described into the second step of the same input sheet. When re-input is judged by this sheet, at the center recognizing device, a recognition window switching part is switched to the second step, and the input of the second step is recognized and returned by the confirmation slip 12. When the transmitted recognized result is corrected, at the facsimile terminal, signals are transmitted to the center recognizing device and transmission is completed.

[Problems to be Solved by the Invention] Conventional facsimile O
Since the CR system is configured as described above, is there a character that cannot be identified by the center recognition device? It is returned to the terminal in the same column as the mark displayed and identified, so that it is difficult to distinguish characters that cannot be distinguished on the terminal side. What is more inconvenient is that the OCR sheet transmitted from the facsimile terminal has only one OCR character entry field, and the original character must be erased and the correct character must be entered for re-correction input. However, there is a problem that the processing on the terminal side is complicated.

The present invention has been made in order to solve the above problems, and an object of the present invention is to eliminate complications such as erasing a defective portion and to improve operability such that a corrected portion can be easily understood. ..

[0006]

In the re-input OCR device according to the present invention, an input having a plurality of writing sections of an initial input stage and a re-recognition stage for re-input is judged to be re-input. With respect to the input, a means for switching the recognition portion and recognizing the character input at the re-recognition stage is provided.

[0007]

In the re-input OCR device according to the present invention, the recognition portion is switched for the input judged to be the re-input, and the input is made to the recognition device.

【Example】

Example 1. FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. Particularly, the configuration of the center recognition device is shown.
In the figure, reference numeral 1 is an input to be transmitted or an input on an OCR sheet shown by a dotted line. Further, 2 is a recognition window switching unit, 3 is a recognition dictionary, and 4 is a recognition unit. 5 is a file,
6 is a control unit, 7 is an output unit, and 8 is a transmission output of the recognition result. The center recognition device 10 is composed of 2 to 7. Figure 2
FIG. 2 is a diagram showing an input sheet indicated by No. 11 of No. 1 and No. 3 of No. 13 which is an example of use of the OCR paper 1 used in FIG. ..

The operation of the embodiment of the present invention will be described. First,
The data of the input sheet 11 shown in FIG. 2 is sent from the facsimile terminal to the center. In FIG. 1, this is input 1. The center recognizing device 10 reproduces the OCR character from the transmitted image data, and the recognizing unit 4 analyzes the character at the stage for initial input with the help of the recognition dictionary 3. have. The result is stored in a file as needed, and then the result has a step of being transmitted from the output unit 7 to the facsimile terminal of the transmission source, for example, as a confirmation form 12. In this case, a character with a low degree of confirmation, that is, a character with a low probability of recognition is output in the second row. When the facsimile terminal sees this and determines that re-input is necessary, only the character to be re-input, such as No. 3, is written in the second row in the same input sheet. It is easy to re-enter without having to erase the original characters. Moreover, the modified part is easy to understand.

In the center recognition device 10, if the number of recognition steps is two, or if it is judged that it is re-input because it is written in the retransmit mark although it is not described, the recognition window switching unit 2
Has a step of switching to the second stage and recognizing the input of the second stage. The center recognition device 10 has a step of returning the recognition result by the confirmation form 12 for the recognition part in the second row. If the received recognition result is correct, the transmission source facsimile terminal sends an end signal to the center recognition device to complete the OCR transmission. If the result is not satisfactory and re-input is necessary, the input sheet 13 of FIG. 2 is erased the second stage this time, re-filled, and the transmission is repeated. The subsequent processing is as described above.

Embodiment 2. In the above embodiment, the re-inputting method using the facsimile has been described, but it may be applied to an OCR device capable of recognizing independent re-inputting. That is, FIG.
For the OCR input of the formats of the input sheets 11 and 13 of FIG. 1, the OCR device 10 having the configuration of FIG. 1 has the recognition window switching unit 2 and includes the following means. For the initial input, the OCR character at the initial stage, for example, the first stage is read. If it is determined that the re-input is made, the recognition window is switched and the OCR character in the second re-recognition stage is read, for example. In response to the normal termination signal, the control unit replaces the data in the re-recognition stage and the file 5
Accumulate in.

[0012]

As described above, according to the present invention, the OCR
Since the device is provided with a means for switching the recognition window for re-input for re-recognition, the entry for re-input on the OCR sheet does not have to be erased, and the correction character is simple. It has the effect of being easy to understand.
