Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a seal verification device, which reads and stores the seal imprint of a contract seal in a financial institution such as a bank, and is capable of reading and storing a seal imprint of a contract seal and a seal later presented by a customer. (Prior Art) Conventionally, as shown in FIG. 4, this type of device has a file device a for storing seal imprint data, a file device a for reading the seal imprint of a contract seal, and registering it in the file device a. It is generally composed of a registration/verification section that reads out the seal imprint data and compares it with the seal imprint to be verified.

To explain the operation of the above configuration, first, the seal impression of the contract seal is read by the imaging device 1, and then, in the extraction circuit 2, parts unnecessary for registration, such as characters and ruled lines on the slip, are removed, and only the seal impression is extracted. , operate switch 3 to record on file device a.

The above-mentioned extraction operation is performed by first displaying a slip with a contract seal stamped on the display 4, then displaying two cursors each in the vertical and horizontal directions on the display 4, and adjusting the cursors to define the screen area to be registered. , by removing only the seal impression.

In the case of verification, first, the seal impression data from the file device a is temporarily stored in the memory 5, and this image is displayed on the display 4. On the other hand, as in the case of seal impression registration, the document with the stamp to be verified is captured by an imaging device! A sampling circuit 2 removes unnecessary images, extracts only the seal imprint to be verified, and displays it on a display 4. That is, the operator superimposes the registered seal imprint of the contract seal stamp and the to-be-verified seal imprint on the display 4 and compares them.

(Problem to be solved by the invention) However, in order to extract only the seal imprint from the slip during registration and verification, the screen area is defined by displaying and adjusting the kernel on the display, so this extraction operation is difficult. This is a major cause of poor service at counter operations.

SUMMARY OF THE INVENTION In view of the above problems, it is an object of the present invention to provide a seal verification device that has a simple configuration and facilitates verification.

(Means for Solving the Problems) In order to solve the above problems, the present invention makes it possible to set and select several external shapes of seal impressions to be registered in the reading section and the collation section, and the filing device The external shape data is recorded together with the seal imprint data, and both data are read out during verification.

(Function) With the above-described configuration, the present invention reads out both seal impression data and outline data during verification, and extracts the seal impression to be verified based on this outline data.

(Example) Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram of one embodiment of the present invention, and the same components as in FIG. 4 are given the same reference numerals. FIG. 2 is a front view of the external shape selection switch 30 of FIG. 1.

This device consists of a file device A for recording seal imprint data and external shape data indicating the shape and size of the seal imprint, and a file device A for recording the seal imprint of a contract seal and its external shape.
It is generally composed of a registration/verification section B which registers the seal imprint data and external shape data and compares them with the seal imprint to be verified.

The registration/verification unit B includes an imaging device 1 such as a TV camera or an image sensor, and a shape selection switch 3 for selecting the shape and size of the shape and size of the registered seal impression, as will be described later.
0, a sampling circuit 20 that extracts the image read by the imaging device 1 in the shape selected by the shape selection switch 30;
It includes a display 4 such as a CRT, and a memory 5.

As shown in FIG. 2, the external shape selection switch 30 is used to select three sizes (large, medium, and small) when the external shape of the seal imprint is round, oval, or square. It has become. The extraction circuit 20 includes an external shape selection switch 30
An image area is defined by the shape and size selected in , and a signal is generated that causes this area to be at a high level. This signal is logically ANDed with the image signal from the imaging device 1, and only the necessary images are extracted.

Next, the operation of the embodiment according to the above configuration will be explained.

FIG. 3 shows an image read by the imaging device 1 and displayed on the display 4, and FIG. 3 0) shows a round stamp 40a1.
FIG. 3(B) shows an oval-shaped seal impression 41a, and FIG. 3(C) shows a square-shaped seal impression 42a. In this case, since the seal is stamped on the slip, the stamp frame image 40b and stamp mark 40c of the slip are also displayed in the same way. Therefore, when registering the impression of a contract seal or when comparing the registered seal impression with the seal impression to be verified, these unnecessary images must be removed.

First, the case of seal impression registration will be explained. Here, Figure 3 (a)
The seal impression displayed in ~(c) is an image of the contract seal.

Therefore, the operator selects the displayed seal impressions 40a to 4.
Depending on the shape and size of 2a, one of the external shape selection switches 30 shown in FIG. 2 is selected and operated. Accordingly, the chip extraction circuit 20 generates an image signal of the selected external shape, and causes the display 4 to display the image. The operator can monitor these two images and position the slip in the horizontal, vertical, and rotational directions, and also operate the external shape selection switch 30 again to select the stamp 40.
The most appropriate external image can be selected and displayed for a to 42a. Note that the above-mentioned monitor operation is convenient if the seal impressions 40a to 42a and the external image are displayed in different colors on the display 4.

When only the seal impressions 40a to 42a are included in the external image by the above operation, the image is extracted by the extraction circuit 20 and stored in the file device A. At the same time, the outline data selected by the outline selection switch 30 is transferred to the file device A.
to be memorized.

Next, the operation of seal verification will be explained.

First, the seal impression data and outline data recorded in the file device A as described above are read out, temporarily stored in the memory 5, and then displayed on the display 4. On the other hand, the operator looks at the external shape data of Disgray 4 and presses the external shape selection switch 3.
When the external shape is selected with 0, this external image is displayed on the display 4. Further, when the slip with the stamp to be verified is read by the imaging device 1 and displayed on the display 4, the operator adjusts so that only the stamp to be verified is included in the external image, and erases unnecessary images. Then, the registered seal imprint and the to-be-verified seal imprint are superimposed and compared.

In the above embodiment, the file device is configured to store seal imprint data and outline data, but in addition to these data, position data of a registered seal imprint on a slip may also be stored.

(Effects of the Invention) As described above, according to the present invention, data on the external shape of the seal impression is stored together with the seal impression data, and this data is read out, so that seal stamp verification can be easily performed.
