The entire display or the enlarged portion is permitted or not permitted according to the presence or absence of the check in the check box 126. An image display area 121 to be displayed and a character string of items 1 to N (each item corresponds to one of the above-described character string IDs) are initially displayed based on the recognized character data file 153, and these characters are further displayed. Character input areas 122 to 125 for performing display accompanying input for changing a column are included. (Especially, if the check in the check box 126 is released while the character string is being enlarged and displayed as shown in FIG. 7, the entire FAX document shown in FIG. 6 is displayed.
As shown in FIG. 6, even if any of the items 1 to N is selected when the check in the check box 126 is canceled and the entire FAX document is displayed, the display of the image display area 121 is not changed. It will be. In the recognition character data correction process, as shown in FIG. 4 (and FIG. 2),
First, the whole image display control unit 732 displays the whole one FAX document in the image display area 121 (S
1) The character strings included in the FAX document displayed as a whole are sequentially displayed in the character input area 1 by the character string display control unit 733.
It is displayed on 22 to 125 (S2).

When these processes are completed, actually, FIG.
Is displayed as shown in FIG. An entire FAX document is displayed in the image display area 121, and the FAX
Character strings "ABC", "1234", "
Aioe is the character string "ABG" (item 1),
Character string "1234" (item 2), character string "Aieo"
(Item 3), the character input areas 122-1
25.

Subsequently, a part of the character string displayed entirely on the image display area 121 and a character input area 122 are displayed.
It is determined whether or not the item k (k is any of 1 to N) has been selected, for example, by clicking a mouse or the like while the pointer is over any one of -125 (S3 in FIG. 4).
If item k is not selected (No in S3), the process is skipped to S10, and if item k is selected (Yes in S3), position information corresponding to item k is obtained by display position setting unit 734. Then, the center position of the image display (image display) is set based on the obtained position information (S5).

After that, the enlarged display control unit 735 displays the FAX document (part) enlarged at a predetermined magnification in the image display area 121 (S6), and inputs an item k using a keyboard or the like. It is received by the control unit 731 (S7). When accepting such input,
A display screen 120 as shown in FIG. 7 is displayed. Here, the character string “AB” erroneously identified as the character string “ABG” by the processing in the file generation unit 171 in accordance with the selection of item 1 (the hatched pattern indicates the selection by the user)
C "is displayed in an enlarged manner, and the user is about to input a correct character string" ABC. "(When another item is selected, the enlarged display is performed similarly to prompt the user to input. The input by the user is performed in accordance with the enlarged display of the character string on the image display area 121 and a predetermined key operation or the like is performed, thereby determining whether or not the input for the item k is completed. If the input for the item k has not been completed (No in S8), the process returns to S7, and if the input for the item k has been completed (Y in S8).
es) The recognition character data for the item k is updated by the input control unit 731 and the recognition character data file 153 is updated.
Is rewritten (S9).

After these processes, it is determined whether or not a predetermined key operation for ending is performed (S10), and if no key operation for ending is performed (No in S10), S
The process from Step 3 is repeated, and if such a key operation is performed (Yes in S10), the main recognition character data correction process ends. As described above, in the FAX-OCR device 1, when the user corrects the recognition character data generated for the character string in the FAX document, the character string is enlarged and displayed according to the selection of one character string by the user. Therefore, the association between the image data in the image display area and the character input area where the input is being performed is easily confirmed, and the user is displayed in the character string displayed in the image display area and in the character input area. It is possible to concentrate on the comparison with the character string and the correction of the character string required according to the result of the comparison, and it is possible to efficiently correct the recognized character data with good operability.

Also, in the FAX-OCR apparatus 1, since the inclination, displacement, etc. of the image data itself are corrected prior to the correction of the recognized character data, the character string to be input can be accurately determined according to the user's selection. The image is enlarged and displayed in the vicinity of the center of the image display area, and unnecessary image data is assumed to be deleted in advance. Therefore, when correcting the recognition character data, the user compares the two character strings with the comparison result. It is possible to concentrate on the correction of the corresponding character string, and the work efficiency is improved.

Further, the FAX-OCR apparatus 1 performs enlarged display including the periphery of a character string without correcting the inclination and displacement of the image in advance. Differently, even if the image portion corresponding to the character string in the FAX document is inclined or specified to be shifted up, down, left, and right from the position to be specified, the character to be input is displayed as an image. Since it is included in the area, it is possible to prevent the correction (input) of the recognized character data from being hindered.

In the above embodiment, the image display area and the character input area are arranged on the same screen.
These two regions may be arranged on different screens. In addition, the permission or non-permission of the enlarged display is instructed according to the presence or absence of the check in the check box.
Hard keys can be used.
