Abstract

PURPOSE:To save labor for inputting in document retrieval by recording the picture information of a document after adding the position information of a keyword area in the document filing device concerning the storage and retrieval of the picture information of the document. CONSTITUTION:A control part 12 reads a document 11 by a scanner 10 and displays the picture information on a display 13. By observing a document 14 on the display 13, an operator designates a start point 16a and an end point 16b of a keyword area 16 by a mouse 15. The control part 12 records the picture information of the document 14 after adding addresses for the start point 16a and the end point 16b of the keyword area 16 by the scanner 10. When the keyword of the document to be retrieved is instructed from a keyboard 21, the control part 12 takes out the keyword area 16 of each document, recognizes characters by a character recognition part 22 and defines them as keyword information. Then, the control part 12 compares the above-mentioned keyword with the keyword information and outputs the coincident information.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document filing device, and more particularly, to a document filing device that stores image information of a document and retrieves the image information of the stored document as necessary. .

In recent years, as a labor-saving device for processing documents that are generated in large quantities, image information is retrieved by optically scanning the document, and storage devices such as optical disk devices are used along with search data input corresponding to this image information. Document filing devices have been put into practical use that store and store documents (file them), retrieve them as needed, read them out, display them on a display, or print them (hard copies).

[Conventional technology]

In conventional devices, keyword information for searching image information is inputted from a keyboard or the like at any time when filing image information, and is stored together with the image information.

In addition, it is possible to specify the part of the optically scanned and read image information that you want to extract as keyword information using an area pointing device such as a mouse, and that part is character-recognized and automatically stored as keyword information along with the image information. be.

[Invention or problem to be solved]

In a conventional document filing device that inputs keyword information using a keyboard, it takes time and effort to input the keyword information. Furthermore, in conventional devices that extract keyword information from image information, if a character is incorrectly recognized during the character recognition process, it is necessary to correct the erroneously recognized character, and this correction process is time-consuming.

Furthermore, all conventional devices store keyword information of variable length in addition to image information for each document, and when the keyword information is long, the amount of keyword information to be stored becomes large.

The present invention has been made in view of the above points, and an object of the present invention is to provide a document filing device that does not require inputting keyword information and requires only a small amount of keyword information to be stored.

[Means to solve the problem]

FIG. 1 shows a diagram of the principle of the device of the present invention.

During the reading, the reading means 1 reads the document as image information.

The area specifying means 2 specifies a keyword area on the image information of the document.

The recording/reproducing means 3 records image information of a document with position information of a keyword area added thereto, and reproduces the image information.

The keyword input means 4 inputs a keyword for searching a document.

The character recognition means 5 extracts the keyword area indicated by the position information from the image information of the document reproduced for each document by the recording and reproducing means 3, performs character recognition, and obtains keyword information.

The comparison means 6 compares the keyword information with the keyword inputted by the keyword input means 4, and when they match, extracts the image information of the document.

[Effect]

In the present invention, the position information of the keyword area on the image information is added to the image information and recorded instead of the keyword itself, so even if the data length of the keyword information becomes long, the amount of keyword information to be recorded can be reduced. In addition, keyword information can be specified by specifying an area and singing without the hassle of inputting information.

〔Example〕

FIG. 2 shows a block diagram of an embodiment of the device of the present invention.

In the figure, IO is a scanner that reads the document 11 to obtain image information. This image information is supplied to the control unit l2,
From here, it will be displayed on the display 13. The operator looks at a document 14 as shown in FIG.
and end point 16b, and specify this starting point 16a and end point 16.
The position information of b is supplied to the control unit 12. As shown in FIG. 4, the control unit 12 receives document image information 1 from the scanner lO.
Addresses 18 and 19 of the start and end points of the keyword area 16 on this image information are added to 7 and recorded in the optical disk device 20.

When a keyword of a document to be searched is specified from the keyboard 21, the control unit 12 sets the address 1 of the start point and end point on the image information for each document reproduced from the optical disk device 20.
8. Extract the image information of the document specified in step 19, that is, the keyword area 16.

The keyword area 16 of each document is character-recognized by a character recognition unit 22 and is used as keyword information. The control unit compares the keyword information for each document with the keyword input from the keyboard, and when the two match, displays the document on the display 13 and, if necessary, prints the document on the printer 23.
Output from

FIG. 5 shows a flowchart of the search process executed by the control unit 12.

This process is started when a keyword is input, and first, in step 30, only the beginning of each document is performed, and it is determined whether the document has ended (step 31). If there is a document, the keyword area 16 is cut out from the image information 17 of the document according to the start point and end point address 18. 33). Thereafter, the recognized keyword information is compared with the keyword input from the keyboard (step 34), and if they are different, the process returns to step 30. If they match, the image information of the document cued above will be displayed on the display 13.Step 3
5) and determine whether to continue the search (step 3).
6) If the process is to be continued, the process returns to step 30; if the process is not to be continued, the process is terminated.

In this way, the positional information of the keyword area on the image information is added to the image information and recorded instead of the keyword itself, so even if the data length of the keyword information becomes long, the amount of keyword information to be recorded can be reduced. In addition, keyword information can be specified simply by specifying the area, without requiring any inputting effort.

In the above embodiment, one keyword area is specified for one document, but multiple keyword areas may be specified for one document.
It is not limited to the above embodiments.

〔Effect of the invention〕

As described above, according to the document filing device of the present invention,
It does not require any effort to input keyword information, and the amount of keyword information to be stored is small, which is extremely useful in practice.
