Description

Detailed Description of the Invention (a1 Technical Field of the Invention) The present invention relates to an image registration system that cuts out and registers the entire or partial image data of a document, etc., and particularly relates to an image registration system in which the cutout area of an image is automatically determined. Regarding the method.

(b) Technical background In recent years, facsimile machines that read documents, drawings, etc. and transmit image data have rapidly become popular as a part of streamlining 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 and projects it onto an image sensor through an optical lens to obtain image data corresponding to the stamp, which is then compared with the image data of the registered seal.
This verification may be performed by transmitting data between stores.

The seal verification machine has a seal registration function and a verification function.
In addition to seals, addresses, company names, and names may also be registered and verified.

When registering a part of these documents or a seal, the image area is cut out and registered as image data, the white part other than the stamp 2 reflects, and the reflected light is stored in a file, but the cutting operation is easy. is requested.

(C) Prior art and problems Hereinafter, a conventional method will be explained using a seal verification machine as an example with reference to FIGS. 1 to 4. FIG. 1 is a perspective view showing the main part of the head of a verification device to which the present invention is applied, and FIG.
3 is a block diagram showing a conventional method, and FIG. 4 is an explanatory diagram of FIG. 3.

As shown in FIG. 1, light from the light source lamp 3 of the reading section 6 illuminates 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 from the vermilion stamp 2.

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 registered image data read out from a registered file 7, and outputted to a CRT (cathode ray tube) 8. Is displayed.

The display unit 8 can display the matching image and the registered image in an overlapping manner to display the matching state and also display the matching rate.

In FIG. 3, which describes a conventional data processing method, reference numeral 1o denotes an input image storage 7a, which holds image data read by the image sensor 5 of the reading section 6.

Reference numeral 11 denotes a data calculation control unit that calculates the image center of the image data in the long image buffer 10, cuts out an image area, and controls transfer to the image area sofa 12.

Reference numeral 12 denotes an image storage sofa, which holds the image data sent from the input image buffer 1° corresponding to the image center and image area, and sends the image data to the registration file 7 at the time of registration.
At the time of verification, it is sent to the verification section 14. 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 has a function of holding the registered mark indexed from the registration file 7 at the time of verification and sending it to the verification section 14.

Reference numeral 14 denotes a matching unit that calculates a matching rate by comparing the registered image data sent from the registered image comparison sofa 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 several functions.

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

With such a configuration and function, when registering a seal, the read image data is stored in the input image buffer 10.
After being held in the image data, the arithmetic and control unit 11 calculates the center position and performs area cutting processing, and the image is transferred to the center of the sofa 12 and further stored in the registration file 7.

When performing verification, a pre-registered seal is called up by the account number etc. to the registered image filter 13, and then the verification stamp is read by the reading unit 6 and stored in the input image 10 as verification image data. The comparison image data is subjected to center calculation and area extraction 7 processing in the arithmetic control section 11, and is sent to the image buffer 12. Furthermore, the registered image data and the comparison image data are sent to the people matching section 14 for comparison. The image comparison is displayed on the CRT 8 as an overlapping image and matching rate.

Then, the rotation control unit 15 rotates the image data held in the image rotation sofa 12 to find the maximum matching rate.

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

In addition to verifying seals, we also check parts of document 1, such as addresses,
The purpose of checking company names, names, etc. is not to check the matching rate, but to check whether the contents match.

In such a seal verification machine, the conventional method for registering documents, etc. has been used4.
