DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recognizing device for reading a form, which includes not only a description content in a reject field but also a description content in an error field and a description content in a confirmation field as required. The present invention relates to a field image display processing device capable of displaying on a display in the form of image information.

[0002]

2. Description of the Related Art A recognizing apparatus for reading a form reads and recognizes the contents of description in a field to be read on the form, determines and outputs code information. In such a recognition device, conventionally, for a field including a rejected character, the description content of the field is displayed on a display in the form of image information.

[0003]

In the case of the conventional recognition apparatus, the contents of a field (error field) containing an error as a result of an operator's check in the recognition result, and the operator's confirmation for some confirmation. There is no function to display the description in the field (confirmation field) for which the description is desired to be displayed, if necessary. For this reason, it is necessary for the operator to review the form itself with respect to the error field, and the operator could not efficiently perform processing such as writing correction information on the display screen.

According to the present invention, the content of a description in an arbitrary field or the content of an error in a form is read as an image, and is read under a cursor instruction.
It is an object of the present invention to be able to display the read image on a display.

[0005]

FIG. 1 is a block diagram showing the principle of the present invention. In the figure, reference numeral 1 denotes an image processing mechanism, 2 denotes a display, 3 denotes a display table, 3-1 denotes a confirmation field table, 3-2 denotes an error field table,
3-3 indicates a reject field table, and 4 indicates a definition field.

The image processing mechanism 1 reads the description contents of each field on the form in the form of image information based on the contents of each table 3-i in the display table 3, and holds the image information.

[0007]

The operator specifies a field (confirmation field) for displaying the description content in the form of image information for confirmation on the definition body 4. In addition, fields containing characters that were rejected as a result of recognition processing (reject
Field) is automatically indicated on the definition field 4. Further
It is indicated on the definition 4 fields (error field) containing the character and logic errors exist.

A display table 3 is created for each of the fields specified on the definition body 4. That is, on the display table 3, a confirmation field table 3-1 corresponding to the confirmation table, an error field table 3-2 corresponding to the error field, and a reject field corresponding to the reject field The table 3-3 is created, and the image processing mechanism 1 holds the description contents in the corresponding fields in the form of image information based on the contents of each table.

[0009] The display processing mechanism (notation 6 in FIG. 2), which is not shown, displays the description contents in each field on the display 2 from the image information.

[0010]

FIG. 2 shows an embodiment of the present invention. Reference numerals 1, 2, and 3-i in the figure respectively correspond to those in FIG. 1, reference numeral 100 is an OCR device, and reference numeral 5 is a recognition processing mechanism for reading and recognizing a description content in a predetermined field on a form. , 6 is a display processing mechanism, 7 is a reading table, 8
Indicates a data area, and 9 indicates a cursor position determination unit.

For example, at first, the description content on the form is recognized by the recognition processing mechanism 5. The field containing the character that was rejected during the recognition process is entered in the reject field table 3-3.
Reject field is Ru been instructed.

On the other hand, when the operator designates the above-mentioned confirmation field in advance or after judging the result of the recognition processing, a confirmation field table 3-1 shown in the figure is prepared.
You.

[0013] In addition, based on the result of the recognition process is error-field table 3-2 Ru is created.

Next, from the information in the display table 3, an image
Processing unit 1 stores data in data area 8 in the form of image information.
Stored in each read table are field information 7-1 relating to the field, row information 7-2 where the field is located on the form, and a data area 8 storing the corresponding image information. 7-3 are described. The image information stored in the data area 8 is
The display on the display 2 is performed as follows. The position of the field corresponding to the cursor on the display 2 is determined by the cursor position determination unit 9 and collation is performed to determine whether or not the field matches the contents of the reading table 7 described above.

If they match, the corresponding image information is read out based on the contents of the storage destination 7-3 and notified to the display processing mechanism 6. That is, the description content in the field is read out from the image information stored in the data area 8 and displayed on the display 2.

FIGS. 3 and 4 show a processing flow relating to image reading. (S1): It is determined whether display is performed in units of characters or in units of fields. The case of the character unit will be described later with reference to FIG. (S2): For a field containing a reject character,
The reject field table 3-3 is set. (S3): When the image reading mode is instructed to read also the error field and the confirmation field, the process proceeds to slap (S4), and when only the reject field, the process proceeds to slap (S5). . (S4): As described with reference to FIG. 1, the error field table 3-2 and the confirmation field table 3-1 are set.

When the respective tables are set as described above, the reading table 7 shown in FIG.
Is stored. (S5): The description contents of the corresponding field are read using each table 3-i. (S6): The read image information is stored in the data area 8. (S7): In addition, the reading table 7 is created.

In the processing in units of characters shown in FIG. 4, the following processing is performed. (S8): The image of the rejected character is read. (S9): The read image information of the rejected character is stored. (S10): The reading table 7 is also created.

FIGS. 5 and 6 show a processing flow relating to image display. (S11): It is determined whether the cursor is positioned on the field. In other cases, it can be considered that interactive processing not directly related to the present invention is performed. (S12): The same determination as in step (S1) in FIG. 3 is performed. (S13): Line information and field information of the field are obtained. (S14): The reading table 7 is searched. (S15): If there is a matching read table 7 in the search result, the process proceeds to step (S16). (S16): The content of the description in the corresponding field is read out from the data area 8 and displayed.

As in the case of FIG. 4, in the processing in units of characters, the processing is performed as shown in FIG. (S17): The field information and character information of the field in which the cathode is located are obtained. (S18): The reading table 7 is searched. (S19): If the search table 7 exists as a result of the search, the process proceeds to step (S20). (S20): Based on the contents of the data area 8, the reject character is displayed in a form read from the image information.

[0021]

As described above, according to the present invention, the contents of a description in a desired field can be displayed while being held as image information. For this, the operator, using the screen of the display, mosquito
It is possible to instruct and display with a cursor, and to input a correct character code and the like.
