Description

  The present invention relates to a system for filing a document such as a form as image data, and more particularly to an image data filing system for storing image data according to a method of using image data to be stored.

Conventionally, a document such as a form has been stored in a database as image data, appropriately read out, and changed.
For example, Patent Document 1 below discloses a technique for reading various forms from an image input device, recognizing a part of the image, and storing the result of character recognition together with the form image in a database.

For this reason, access to documents converted to image data stored in the database has to be frequent. The frequent access to documents converted into image data means that the security has been reduced. As a result, there has been a high possibility of falsification or unintentional modification to an imaged and stored document.

  In view of such problems, an object of the present invention is to provide an image data filing system that can quickly search an imaged document and that is not likely to be altered or unintentionally altered. It is to provide.

And a system control unit for controlling the image data generation device and the image data storage database, and for searching a predetermined type of image data among the image data In an image data filing system that stores, reads, and changes image data for indexing, and stores, reads, and changes other predetermined types of image data as filing data for storage in an image data storage database.
The system control unit recognizes characters of the index image data, extracts an image ID number from the character recognition result, reads an image compression rate from the management table based on the extracted ID number, The index data for search and / or filing data for storage are compressed and stored in the image data storage database according to the compression rate.

According to a second aspect of the present invention, in the image data filing system, the system control unit obtains an input time through a signature data reading device that reads information related to a signature recorded on a card by an arbitrary recording unit, and a mobile phone. An input time reading device is connected, and the system control unit uses the signature data read by the signature data reading device and the input time read by the input time reading device as the index image data and / or the filing In addition to the data, it is stored in the image filing database.

According to the first aspect of the present invention, at least two types of data formats, that is, index data for searching from a document (hereinafter referred to as index data) and filing data for storage (hereinafter referred to as filing data) are stored in an image. An input device or a system control unit (hereinafter, these devices are referred to as image generation devices) generates, and the system control unit converts these images into images according to the compression rate associated with the ID number described in the form. Since compression is performed, the compression rate can be determined flexibly, and the database can be operated flexibly.

In the invention described in claim 2 , in addition to the effect of the invention described in claim 1, since copyright data is added to the image data and stored in the image filing database, the copyright information and the image data are collectively managed. be able to.

When these image data are generated by the image input device 90, they are temporarily stored in the image memory 92 of the image input device 90, and then the image data is transmitted to the system control unit.
The image data determination unit 91 of the system control unit identifies the type of the generated image data, and determines the corresponding storage purpose according to the purpose-specific image determination management table.

Next, the copyright information is added to the index data or filing data in the image copyright setting unit 100. The copyright information is added as follows. The signature data 94 is read by the signature data reading device 402, for example, a card reader, from an arbitrary method, for example, an electromagnetically recorded card. The input time is an input time reading device 403, for example, a device connected to the mobile phone 95 via an interface, and reads the time from an external organization through the mobile phone. The signature data 94 and the input time data 96 are collected as copyright information 97 by the copyright information creating apparatus 404 and associated with image data, for example, index data, by the copyright information adding apparatus 405.
The system control unit stores the index data and filing data associated with the copyright information in the image data storage databases 98 and 99.

  When the operator searches for a document, the system control unit searches for index data. At this time, copyright information may be used as a search condition. If the document is found, the system controller index data is displayed. In order to improve search efficiency and to modify data for adding comments to a document, the system control unit performs index data. When the operator refers to image data corresponding to the original document, the system control unit displays or prints filing data. When displaying or printing the index data or filing data, the copyright information may be displayed or printed at the same time by the system control unit.

The main part of the basic composition of the present invention is illustrated. It is the figure which represented typically the system which stores the produced | generated image data in an image data storage database according to the "image determination management table classified by purpose" which defined the storage objective to a database according to the kind of image data. In addition to FIG. 2, a system for compressing images and storing them in the image data storage database according to the “image processing management table for each purpose” that defines the compression method of image data according to the purpose of storage in the database is schematically shown. FIG. FIG. 3 is a diagram schematically showing a system that compresses an image and stores it in an image data storage database in accordance with a compression rate determined in advance according to the form size in addition to FIG. 2. In addition to FIG. 2, a diagram schematically showing a system for determining whether or not to perform character recognition according to the purpose of storage in the database and compressing an image at a different compression rate depending on the character recognition result and storing it in the image data storage database It is. FIG. 3 is a diagram schematically showing a system for recognizing index data used for search in addition to FIG. 2 and extracting a keyword from the result and storing it in an image data storage database. FIG. 3 is a diagram schematically showing a system in which image data is compressed at a compression rate for each predetermined form size and stored in an image data storage database in addition to FIG. 2. FIG. 3 is a diagram schematically showing a system for correcting an image in accordance with the purpose of storage in a database and storing the corrected image data in an image data storage database in addition to FIG. 2. It is the figure which represented typically the system which adds copyright information to image data, and stores it in an image data storage database. FIG. 10 illustrates an arrangement of devices in FIG. 9. FIG. 7 shows the arrangement of devices in FIGS. 5 and 6. FIG. 10 illustrates an arrangement of devices in FIG. 9. It represents the processing flow of FIG. FIG. 10 illustrates the processing flow of FIG. 9.
