Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an image storage device that stores image information obtained by scanning images such as drawings and seal impressions in a storage unit.

[Technical background of the investigation and its problems]

An example of this type of image storage device is seal registration.

It is possible to improve the seal verification device used for seal verification operations such as seal verification and seal searches performed by financial institutions.

Seal verification operations at financial institutions involve not only comparing the impression of the seal brought with you to verify your identity when withdrawing money with the impression on the seal book, but also confirming the bearer's address and name, etc., as necessary. Conventional seal verification equipment for performing such seal verification work uses paper, microfilm, etc. as a medium to check the stamp stamped on the application form when opening an account, as well as the address and name stamped out. If you create a seal fiii rumor and use the search key to enter the account code when withdrawing money, the corresponding seal impression in the seal book and the seal you brought will be displayed on the screen, allowing the operator to check the information. It is configured to be provided.

However, in a device that uses a seal register using paper, microfilm, or the like as a medium, it takes time to search for a corresponding seal register, and cannot contribute to efficient seal verification operations. For this reason, there is a need to create a seal register using an easily searchable medium such as a magnetic disk or an optical disk. Furthermore, in order to meet this request, the partial nature of the image to be stored, for example, the seal part requires high-resolution image information for seal imprint verification, and the part where the address etc. is written needs to be high resolution so that the characters can be read *τ It is necessary to create a seal book in accordance with the nature that image information of relatively low resolution is sufficient, in view of downsizing and effective use of storage units such as magnetic disks.

[Purpose of the invention]

The present invention has been made in view of the above circumstances, and its purpose is to reduce the size and increase the storage capacity of a storage unit that stores image information obtained by scanning images. The objective is to provide an image storage device that can.

[Summary of the invention]

In order to achieve the above object, the present invention stores image information in a specific area of an image to be stored at a resolution different from that in other areas.

This is the second scanner that can obtain . As this second scanner 2, for example, a facsimile scanner having a line sensor can be used.
) can scan an A4 size area. Then, there is an operation section 6 for specifying operation modes such as seal book creation mode or seal imprint verification mode, inputting search data such as account number, etc., and ° verification for performing seal imprint verification based on the created seal register. Terminal unit 4 and a first storage area A411 for storing search data such as an account number shown in FIG. 2 in order to store the image information of the application form in a searchable format. (Also called seal impression information)? The storage unit 5 has a plurality of searchable directories, including a second storage area M2 for storing image information of the entire application form (hereinafter also referred to as seal register information) and a sixth storage area M3 for storing image information of the entire application form (hereinafter also referred to as seal register information). For example, the control device 6 serves as a processing unit that processes a specific area (seal impression area) of the image (image of the application form) to be stored and stored in the image information total storage unit 5 at a resolution different from that of other areas. It is provided. Note that as the storage section 5, a magnetic disk or an optical disk can be used.

The verification terminal section 4 is configured as shown in the block diagram shown in FIG. 6, for example, and an interface circuit 10 is connected to the control device 6.
A first frame memory 11A stores the seal imprint information transferred from the second storage area M2, and stores the to-be-verified seal imprint information obtained by the first scanner 1. the second frame memory 11B, and the sixth frame memory 11B;
A sixth frame memory 11C that stores the seal book information transferred from the storage area M3 is connected. and the first and second frame memories 11A, 11
A matching circuit 12 is provided for normalizing the positional deviation between the two seals by rotational movement and parallel movement and superimposing them when comparing the two seal impressions based on the stored contents of the seals 12. The first frame memory 11A, the second
frame memory 11B and sixth frame memory 11
C is connected to a display control circuit 16, and this display control circuit 16 is configured to display the information in the selected frame memory and the verification result in the verification circuit 12 on the display section 1-4. Note that this display section 14 is, for example, a CR
It consists of a graphic display device using T.

Next, the operation of the device of the first embodiment will be explained. This device can select and execute six operation modes: seal book creation, seal imprint verification, and seal book search.

(1) Creation of Seal Registration Book Creation of a seal registration book is initiated by designating the seal registration book creation mode on the operation section 6.

First, an application form on which the new customer's name and address, newly assigned account number, etc. are written and a seal is affixed is scanned by the first and second scanners 1 and 2. That is,
The control device 6 causes the second scanner 2 to scan the entire application form and stores the obtained seal book information in a sixth storage area M3 of an empty directory in the storage section 5. The first storage area Mll/(: stores the account number, scans the seal imprint on the application form with the first scanner 1, and stores the obtained seal imprint information in the second storage area Mll/(:) of the directory. is stored in the storage area 1V12.

In the seal book created in this way, the 16 seal impressions stored in the second storage area 1v12 have a resolution of 16 (books/y1) so that detailed seal impressions can be verified. Sixth memory, the seal & book information stored in memory area M3 is enough for 8 lines (book/,
,) has a resolution. Let us consider the total amount of stored information when image information is stored in a specific area of an image at a resolution different from that in other areas. For example, assume that the application form size is 5th (210HX 150m5) and the maximum size of the seal imprint is 50+yaX, 30m. At this time, when comparing the total storage information amount C8 when the image information of the entire application form is obtained at a resolution of 16 (books/u) and the total storage information iC1 when stored as in the above example, it can be seen from the following formula: As is clear, in the case of this embodiment, the total amount of stored information is reduced to about 1/3, and it is possible to achieve miniaturization of the storage section for storing image information and increase in storage capacity.

(2) Seal Imprint Verification When performing seal imprint verification, the customer specifies the seal imprint verification mode using the operation section 6 and inputs the customer's account number. Then, the control unit 6 searches the storage unit 5 for the directory with the account number that matches the input account number, and stores the seal imprint information stored in the second storage area [42] of the directory in the first frame memory. Transfer to 11A. In addition, the first scanner 1 described in t4iJ scans the stamp imprint to be verified, which is affixed on a transaction application form, etc. that the customer hands to the bank staff at the time of deposit withdrawal, etc. Transfer to memory 11B. The seal imprint information and the to-be-verified seal imprint information thus transferred to the frame memories 11A and 11B are transferred to the collation circuit 12, where the positional deviation between the two is normalized and a direct alignment is performed. When it is determined that the two match, the display control circuit 1
6, a message indicating that they match is displayed on the display section 14. When it is determined that there is a mismatch, the display control
A display indicating that there is a mismatch and an image corresponding to the information of both seal impressions are displayed on the display section 14 via m13. If the circuit 12 is omitted, for example, images corresponding to both seals, curses, shadows, and trepidation will be displayed on the display unit 14 in different colors, such as red and green, and a match or a small match will be determined by the operator's visual inspection. . Particularly in this case, since the two displayed images have different colors, the overlapping portion is displayed in yellow, which facilitates visual judgment.

(3) Seal Book Search When performing a seal book search, K specifies the seal book search mode on the operation unit 6 and inputs the customer's account number. Then, the control unit 6 searches the storage unit 5 for a directory with an account number that matches the input account number, and stores the seal book information stored in the sixth storage area M3 of the directory in the sixth frame memory. 11C, and an image corresponding to the transferred information is displayed on the display unit 14 via the display control circuit 16. The images displayed in this way are used to confirm whether the characters in the name written on the transaction application form that the customer hands to the bank staff when making a deposit withdrawal, etc., match the characters stored in the register. It will be used to

Next, a second embodiment of the present invention will be described.

FIG. 4 is a block diagram showing a seal verification device according to a second embodiment of the present invention. The same members as those described in the first embodiment are given the same reference numerals, and detailed explanation thereof will be omitted.

Book/+u A second image processing section 22 that converts 4C into seal book information and a control device 26 that controls each section convert image information to a specific area of the image to be stored at a resolution different from that of other areas. The processing unit 24 that processes the data to be stored in the storage unit is configured. Since the form of the application form is constant, the position of the seal imprint on the application game is determined in advance, so that the first image processing section 21 can reliably extract the seal imprint information. Also, the second image processing unit 2
The conversion of resolution in step 2 is performed by a linear coordinate transformation called affine transformation, and especially when the resolution is summed by half as in this embodiment, the average value of four adjacent points of image information before conversion is The conversion process is extremely easy because it is only necessary to calculate the value and use it as the converted value. With this configuration as well, it is possible to reduce the size of the storage unit that stores image information and increase the storage capacity, similar to the first embodiment.

It should be noted that the above embodiment is merely an example, and it goes without saying that many modifications can be made within the scope of the spirit of the present invention. For example, the image to be memorized is not limited to the stamped application form as in each of the above embodiments, but can also be applied to drawings, etc. In short, the information density of the images is partially different. It can be applied to any image.

Further, the resolution of the image information for the specific area and other areas of the image is 16 lines/dragon as in the above embodiment.
