The coordinates (Y2) are obtained by the above-described coordinates (Y2) calculation processing.
In this way, the coordinates P2 (X2, Y2) shown in FIGS. 7B and 7C are obtained by the processing in the flowcharts of FIGS. 9A and 9B. Then, coordinates P1 (X1, Y1) and P2 (X2, Y2) are used in step S46 in FIG.

  In the second embodiment, the case where the seal imprint 30b of the verification mark is circular is described as an example, and the present invention can be similarly applied to the case where the seal imprint 30b is elliptical. The shape of the seal 30b is not limited to these cases, and may be rectangular. Steps S42a to S42e (FIG. 8A) when the seal 30b is a rectangle (a square as an example) will be described with reference to FIGS. 11 and 8A.

  FIG. 11 is a diagram illustrating a coordinate acquisition process performed by the seal verification device according to the second embodiment. FIG. 11A shows a case where a vertical scanning line and a horizontal scanning line are set for the rectangular seal 30b. FIGS. 11B to 11E respectively show scanning of a vertical scanning line in the X direction (right direction).

  When a designated point (X0, Y0) is specified on the imprint 30b also for the rectangular imprint 30b, as shown in FIG. A vertical scanning line and a horizontal scanning line passing through the point (X0, Y0) are set respectively (step S41: FIG. 6). Then, the seal imprint extracting unit 25 executes the following processing of FIG.

[Step S42a] The seal stamp extraction unit 25 acquires the (X component) coordinates (X0) of the designated point acquired in step S30 of FIG.
[Step S42b] As shown in FIGS. 11B to 11E, the seal imprint extracting unit 25 moves the vertical scanning line from the designated point (X0, Y0) in the X direction (rightward) of the seal 30b. Dot scanning.

[Step S42c] The seal imprint extracting unit 25 determines whether there is one set of pixels on the vertical scanning line for the seal 30b.
In the next process, when the seal imprint extracting unit 25 determines that the set of pixels on the vertical scanning line for the seal 30b is one, the process proceeds to step S42d, and until then, the process is repeatedly performed to step S42b.

  For example, in FIGS. 11B to 11D, the set of pixels on the vertical scanning line for the imprint 30b is three and two, so that the vertical scanning line is further scanned to the right. In FIG. 11E, since there is only one set of pixels on the vertical scanning line for the seal 30b, the process proceeds to step S42d.

[Step S42d] The seal stamp extracting unit 25 acquires the coordinates (Xa) of the vertical scanning line when the number of pixels on the vertical scanning line for the seal 30b is one (see FIG. 11E).
[Step S42e] The seal imprint extracting unit 25 calculates the coordinates (X1 (= Xa + α)) by adding an arbitrary value α to the coordinates (Xa) acquired in step S42d (see FIG. 11E). . The value α is appropriately set according to how much gap is provided between the seal 30b and the seal 30b. In some cases, the value α need not be set.

The coordinates (X1) are obtained by the above-described coordinates (X1) calculation processing.
The coordinates P1 (X1, Y1) and P2 (X2, Y2) in the case of the rectangular seal 30b are obtained by similarly executing the processing of steps S43 to S45 on such a rectangular seal 30b. Can be

  In the seal verification system 10 described above, an image 30a of the printing surface of the transaction voucher in which the verification mark to be verified is stamped on the printing surface is obtained, and any one of the specified designations on the imprint 30b of the verification mark is obtained in the image 30a. The imprint area 30d of the imprint 30b is specified from two intersections obtained by scanning the vertical scanning line and the horizontal scanning line passing through the point in the X direction (left and right direction) and the Y direction (up and down direction), respectively. The seal 30b in 30d is extracted, and the extracted seal 30b is compared with the notification seal.

  In such a seal stamp collation method, an imprint area 30d is moved with respect to the seal imprint 30b of the collation mark, and any specified point on the seal imprint 30b of the collation mark is clicked with the mouse 32 without adjusting the size. By simply designating, the imprint area 30d for the imprint 30b can be specified. Therefore, it is possible to easily extract the seal imprint 30b of the verification seal from the read transaction slip, and it is possible to efficiently proceed to the subsequent seal verification.

[Third Embodiment]
In the third embodiment, a case where a seal imprint extraction process different from that of the second embodiment is used will be described with reference to FIGS. In the third embodiment, the seal verification process (FIGS. 4 and 5) is performed using the seal verification system 10 (FIGS. 2 and 3) of the second embodiment. In this seal verification process, the following seal extraction processing is executed.

  FIG. 12 is a flowchart illustrating a seal imprint extracting process performed by the seal stamp collation device according to the third embodiment. In the flowchart of FIG. 12, the same processes as those in the flowchart of FIG. 6 are denoted by the same step numbers.

  FIG. 13 is a diagram illustrating a seal imprint extraction process performed by the seal stamp collation device according to the third embodiment. 13A shows the coordinates P1 (X1, Y1) set for the seal 30b, and FIG. 13B shows the seal area 30d set for the seal 30b.

  [Step S41] As shown in FIG. 7A, the seal imprint extracting unit 25 sets a vertical scanning line and a horizontal scanning line that pass through the specified point (X0, Y0) specified for the seal 30b, respectively. .

  [Step S42] As shown in FIG. 7B, the seal imprint extracting unit 25 converts the coordinates (X1) using a vertical scanning line passing through the designated point (X0, Y0) specified on the seal 30b. It is calculated (see FIG. 8A).

  [Step S43] As shown in FIG. 7B, the seal imprint extracting unit 25 calculates the coordinates (Y1) using a horizontal scanning line passing through the designated point (X0, Y0) specified on the seal 30b. It is calculated (see FIG. 8B).

  [Step S50] As shown in FIG. 13A, the seal imprint extracting unit 25 sets the coordinates P1 (X1, Y1) for the seal 30b using the coordinates calculated in steps S42 and S43.

  [Step S51] As shown in FIG. 13B, the seal imprint extracting unit 25 sets the rectangular imprint area 30d defined in advance at the coordinates P1 (X1, Y1) (first intersection) set in step S50. Superimpose one of the vertices of. As a result, the imprint area 30d can be specified for the imprint 30b.

  The imprint area 30d used here is defined according to the size of the imprint of a generally used seal. Therefore, the size of the imprint area 30d can be appropriately changed in advance.

[Step S46] The seal imprint extracting unit 25 extracts the seal 30b in the seal area 30d specified in step S51.
[Step S47] The seal imprint extracting unit 25 converts the extracted seal imprint 30b into image data.

  By the above imprint extraction processing, the imprint 30b can be extracted and converted into image data. Then, the seal verification device 20 can execute the processing of steps S50 and S60 in FIG.

  In the third embodiment, the case where the coordinates P1 (X1, Y1) of the second embodiment are used in step S50 is described, but the coordinates P2 are used instead of the coordinates P1 (X1, Y1). (X2, Y2) may be used.

  In the seal verification system 10 described above, an image 30a of the printing surface of the transaction voucher in which the verification mark to be verified is stamped on the printing surface is obtained, and any one of the specified designations on the imprint 30b of the verification mark is obtained in the image 30a. A vertical scanning line and a horizontal scanning line passing through the point are scanned in the X direction (right or left direction) and the Y direction (up or down direction), respectively, at intersections obtained by scanning the predetermined rectangular imprint area 30d. By matching the vertices, the imprint area 30d of the imprint 30b is specified, the imprint 30b in the specified imprint area 30d is extracted, and the extracted imprint 30b is compared with the notification seal.

  In such a seal stamp collation method, an imprint area 30d is moved with respect to the seal imprint 30b of the collation mark, and any specified point on the seal imprint 30b of the collation mark is clicked with the mouse 32 without adjusting the size. By simply designating, the imprint area 30d for the imprint 30b can be specified. Therefore, it is possible to easily extract the seal imprint 30b of the verification seal from the read transaction slip, and it is possible to efficiently proceed to the subsequent seal verification.

Further, the imprint 30b can be more easily extracted than in the case of the second embodiment.
