Description

[Detailed Description of the Invention] (a) Technical Field of the Invention The present invention relates to an electronic file device for a seal stamp matching device that matches a registered image of a seal stamp, etc. with a stamp on a document, and in particular, the present invention relates to an electronic file device of a seal stamp matching device that matches a registered image of a seal stamp, etc. with a stamp on a document, etc. Regarding electronic file devices that can be registered even when

(b) Background of the technology In recent years, facsimile devices that read documents, drawings, etc. and transmit image data have rapidly become popular as part of efforts to streamline office work.

On the other hand, in financial institutions and the like, a method is being attempted in which a seal verification device automatically verifies a customer's stamp on a bill, check, etc. with a registered seal.

The verification device irradiates the stamp to be verified with light, projects it onto an image sensor through an optical lens, obtains image data corresponding to the stamp, and compares it with the image data of the registered seal that has been registered in advance. This is sometimes done by transmitting data between stores.

The seal matching device has a seal registration function and a matching function, and may also register and match not only seals but also addresses, company names, and names.

When registering these seals, etc., they are stored in a registration file, but an index and a corresponding area are set in advance in the registration file, and when that area is full, registration becomes impossible. It is necessary for management to be able to register at any time.

(c) Prior Art and Problems Hereinafter, a conventional method will be explained using a seal verification device as an example with reference to FIGS. 1 to 5. FIG. 1 is a perspective view showing the main part of the head of a verification device to which the present invention is applied, FIG. 2 is a schematic explanatory diagram of the verification device shown in FIG. 1, FIG. 3 is a block diagram showing a conventional method, and FIG. 4 and FIG. 5 are explanatory diagrams of FIG. 3.

As shown in FIG. 1, the light source lamp 3 of the reading section 6
The light irradiates onto the document 1 on which the stamp 2 is written. The irradiated light is focused on the image sensor 5 by the lens system 4 without being reflected at the vermilion stamp 2 portion. That is, the image of the stamp 2 stamped on the document 1 is projected onto the light receiving surface of the image sensor 5, and the image sensor 5 converts the optical image into verification image data.

As shown in FIG. 2, this collated image data is input to a data processing section 9, processed, collated with the registered image data read out from the registered file 7, and outputted to a CRT (cathode ray tube) 8. Is displayed.

The CRT 8 displays the matching image and the registered image in an overlapping manner to display the matching status, and can also display the matching rate.

To explain the conventional data processing method, in FIG. 3, reference numeral 10 denotes an input image buffer, which holds image data read by the image sensor 5 of the reading section 6.

Reference numeral 11 denotes a data calculation control unit which calculates the image center of the image data of the input image buffer 10, cuts out an image area, and transfers it to the image buffer 12.

12 is an image buffer, and input image buffer 10
The image data sent from the controller is held in correspondence with the image center and image area, and is sent to the registration file 7 at the time of registration, and sent to the matching section 14 at the time of verification. It also has a function of rotating the image data by a predetermined angle according to a command from the rotation control section 15 and sending the rotated image data to the collation section 14 .

Reference numeral 13 denotes a registered image buffer, which holds the registered mark indexed from the registration file 7 at the time of verification, and is used by the verification unit 1
It has a function to send to 4.

Reference numeral 14 denotes a matching unit that calculates a matching rate by comparing the registered image data sent from the registered image buffer 13 and the matching image data sent from the image buffer 12, sends it to the CRT 8, and starts the rotation control unit 15. It has the function of

Reference numeral 15 denotes a rotation control section, which has a function of rotating the image data held in the image buffer 12 by a predetermined angle in response to a command from the collation section 14.

With such a configuration and function, when registering a seal, the account number is input from the keyboard 16, and the read image data is stored in the input image buffer 10 and then transferred to the arithmetic control unit 1.
1, the center position is calculated and the area is cut out, the image is transferred to the center of the image buffer 12, and further stored in the registration file 7.

When performing verification, the pre-registered seal is called up to the registered image buffer 13 by inputting the account number as an index, and then the verification stamp is read by the reading section 6 and stored as verification image data in the input image buffer 10. The comparison image data is subjected to center calculation and area extraction processing in the arithmetic control section 11, and sent to the image buffer 12. Furthermore, the registered image data and the comparison image data are each sent to the matching section 14 for comparison. The image comparison is used as an overlapping image and matching rate.
Displayed on CRT8.

Then, the image buffer 1 is controlled by the rotation control unit 15.
The image data held in step 2 is rotated to find the maximum matching rate.

In this way, registration and verification of seals can be performed.

In such a seal verification device, the registration file 7 is explained in detail with reference to FIG.
is an electronic file composed of, for example, a magnetic disk, and in the figure, reference numeral 71 is an index area, in which code data, for example, account numbers, are registered in numerical order in advance, and at the time of registration, the address of the image data is placed at the position of the corresponding account number. An address number indicating the location is recorded.

A data storage area 72 stores image data at an address number position corresponding to the account number of the image data to be registered.

With such a configuration and function, when registering, when an account number is input using the keyboard 16, the address number of the image data is recorded at the position of the corresponding account number in the index area 71, and the address number of the image data is recorded in the position of the account number in the index area 71. When the image data read in step 6 is sent, it is stored in the position of the corresponding address number in the data storage area 72.

When performing verification, when an account number is input, the address number in the index area 71 is used to search for the corresponding address number in the data storage area 72, and the image data is read out and stored in the registered image buffer 1.
Sent to 3.

At this time, a binary search method, for example, is used to speed up the search. As shown in Figure 5, this method is to explain the case where, for example, there are numbers 1 to 10,000 and you want to search for the position of 4,000. Determine if there is. Next 1
Divide into ~2500 and 2501~5000 and determine which of them it is in. In this way, we divide it into two parts one after another, and finally find the position of 4000.

This method averages the search time and shortens the average search time compared to the method of sequentially searching for arbitrary numbers starting from 1.

In this way, registration in the registration file 7 and search during verification can be performed.

However, in the conventional registration file 7, only the account numbers preset and stored in the index area 71 are subject to registration of image data. That is, account numbers other than those registered in advance in the index area 71 cannot be registered.

Therefore, if it is necessary to register image data for an account number that has not been registered, cancel the registration in the registration file 7 midway, register it in a seal register, etc., and then save it at a later date when the capacity of the registration file 7 is full. There is a drawback that when it is expanded, it must be re-registered in the registration file 7.

This is not desirable in terms of operation of a system that uses a seal verification machine, so countermeasures are required.

(d) Purpose of the Invention The purpose of the present invention is to solve the above-mentioned drawbacks, and when registering a seal etc., even when the preset index area is full, or the account number corresponding to the index area is The purpose of the present invention is to provide an electronic file device that can be registered even when there is no electronic file.

(e) Structure of the invention The present invention provides a first
a first data storage area in which image data is registered corresponding to the index of each code data in the index area and the first index area;
a second index area in which code data not set in the first index area is sequentially registered; and a second data storage area in which image data is registered corresponding to the index of each code data in the second index area. This electronic file device is characterized in that it is equipped with the following features, and by doing so, the object can be achieved.

(f) Embodiment of the Invention An embodiment of the present invention will be described below with reference to FIGS. 6 and 7. FIG. 6 is a block diagram showing one embodiment of the present invention, and FIG. 7 is an explanatory diagram of FIG. 6. The same reference numerals indicate the same objects throughout the figures.

In FIG. 6, 17 is a registration file, which includes index areas 71 and 73 and a data storage area 7.
2, 74, and when the index area is full, that is, when the input account number is not registered among the account numbers registered in advance in the index area 71, the account number and Image data is recorded in the index area 73 and data storage area.

Reference numeral 18 denotes a registration control unit that searches whether the account number of the image data to be registered is generally registered in the index area 71 of the registration file 17, and if registered, sets the address number of the image data as the account number. Therefore, the image data is stored in the corresponding address of the data storage area 72, and if it is not registered by the search, the image data is stored in the index area 7.
It has a function to control registration using 3.

The index area 72 is the index area 71
This is to sequentially register account numbers that have not been registered.

With such a configuration and function, when registering image data, if the input account number is not among the account numbers pre-registered in the index area 71, that is, when the index area 71 is full, etc. The image data is registered in the index area 73, the address number of the image data is taken at the same time, and the image data is stored at the corresponding address in the data storage area 74.

In addition to registering image data corresponding to account numbers registered in advance in the index area 71 in this way, the index area 73 in which account numbers can be registered sequentially can be used to register new accounts that are not registered in the index area 71. A seal can also be registered for a number or when the index area 71 is full. In other words, normal registration can be performed as a temporary measure.

Then, when the capacity of the index area 71 and data storage area 72 of the registration file 17 is expanded at a later date, the data is transferred and registered from the index area 73 and data storage area 74, and registered in a regular arrangement.

Since the account number registered in the index area 73 cannot be searched by the binary search method described above, the account number is searched sequentially starting from one end. Therefore, the search takes a long time, but since the number of account numbers registered by such a procedure is limited, the time required is tolerably small.

(g) Effects of the Invention As explained above, according to the present invention, when registering a seal, it is possible to register a seal with an account number other than the account number registered in advance. There is no need to cancel and register using a seal register, etc., and the seal verification system can be operated smoothly.
