The check target imprint storage unit 27 stores the check target stamp D read by the direct scanner 13 of the sales office window terminal 10. And the collation control part 28 controls each part in the stamp collation part 15. FIG.

  Next, the operation of the seal collation process relating to the first embodiment will be described. FIG. 4 is a flowchart of the seal collation process relating to the first embodiment. Prior to the operation of the seal collation process, the customer enters the store number, subject, and account number of his / her account in the form 8 and stamps a delivery stamp as the collation stamp D. Further, the customer gives this form 8 to the person in charge at the sales office window terminal 10. The person in charge who has received this sets the form 8 on the mat of the direct scanner 13 and starts the operation.

  S101: The shop terminal control unit 17 of the shop counter terminal 10 instructs the direct scanner 13 to read the form 8 set on the mat. In the form 8, a store number, a subject, and an account number are described, and a check stamp D is further stamped. The branch terminal control unit 17 instructs the terminal storage unit 16 to extract the checked seal D and store the checked seal D.

  S102: The branch terminal control unit 17 controls an OCR form reading unit (not shown), reads a store number, a subject, and an account number, and determines these information. If the person in charge does not use the OCR form reading unit, the person in charge inputs the store number, subject, and account number using the mouse / keyboard 12. Therefore, the branch office terminal control unit 17 sends these items to the mouse / keyboard 12. Instructs to accept input. These pieces of information are determined by input from the mouse / keyboard 12.

  S103: The store terminal control unit 17 transmits the determined store number, subject, and account number to the seal server 5 of the office center 2 for the seal verification. Then, the seal stamp server 5 is requested for a registered seal stamp, and a registered seal stamp image 32 including the registered seal stamp is acquired. The branch terminal control unit 17 instructs the seal collation unit 15 to extract a correct registered seal stamp from a plurality of registered seal stamp candidates in the acquired registered seal stamp image 32. Details will be described later with reference to FIG.

S104: The branch terminal control unit 17 instructs the display 11 to display a transaction screen at the same time. Thereby, the person in charge performs various inputs.
S105: Upon acquiring the registered seal image 32 including the registered seal image from the seal stamp server 5, the branch terminal control unit 17 instructs the terminal storage unit 16 to store the registered seal image 32 including the registered seal image. Then, the branch terminal control unit 17 instructs the seal collation unit 15 to read out the registered seal imprint stored in the storage unit and to collate the registered seal A with the collated seal D.

S106: The branch terminal control unit 17 instructs the display 11 to display the seal collation screen. Thereby, the person in charge confirms the seal collation screen.
S107: The branch terminal control unit 17 checks whether or not the person in charge has confirmed the seal verification using the mouse / keyboard 12.

S109: If the confirmation by the person in charge is OK, the branch office terminal control unit 17 transmits the completion of the seal verification to the host computer 3 via the financial institution network 4.

FIG. 5 is a flowchart of the registered seal acquisition process relating to the first embodiment.
S201: When receiving the registered seal image 32 from the seal stamp server 5, the verification controller 28 of the seal verification unit 15 instructs the registered seal image storage unit 21 to store the registered seal image 32.
S202: The collation control unit 28 instructs the registered imprint candidate extracting unit 22 to extract one registered imprint candidate from a plurality of imprints in the registered imprint image 32 stored in the registered imprint image storage unit 21. Then, the registered imprint candidate storage unit 23 is instructed to temporarily store the extracted registered imprint candidates.

  As a method for extracting an imprint from the registered imprint image 32, for example, a ruled line in the registered imprint image 32 is removed, and a continuous curve of a black image is determined as an outer frame of the imprint, and the imprint is detected. It shall be performed using the technology of

  S203: The collation control unit 28 instructs the overhang imprint determination unit 24 to determine whether or not the registered imprint candidate stored in the registered imprint candidate storage unit 23 is an overhang imprint. That is, it is instructed to determine whether or not the registered imprint candidates are within the registered imprint image 32. At the same time, it is determined whether or not the extracted number N of registered seal stamp candidates is N <4. When the extracted registered seal imprint candidate is an overhang imprint and N <4, the process proceeds to step 204. Otherwise, the process proceeds to step 206.

  Here, the process for determining the protruding impression performed by the protruding impression determining unit 24 will be described. FIG. 6 is an explanatory diagram showing the determination process of the overhang imprint relating to the first embodiment. 2A shows a case where there are two imprints A and B in the registered imprint image 32, and FIG. 2B shows four imprints A and B1, B2, B3 in the registered imprint image 32. FIG. Show the case. In FIG. 9A, the seal stamp A is contained in the registered seal stamp image 32, and the seal stamp A is later subjected to seal verification. The imprint B is not included in the registered imprint image 32 and is determined to be a protruding imprint as an imprint other than the registered imprint. The protruding seal B is excluded from the seal verification target. In FIG. 5B, the overprinting imprints B1 to B3 as imprints other than the registered imprint are excluded from the seal verification targets. In the protruding impression determination process, each imprint is extracted as a candidate, and it is determined whether or not it is an protruding impression according to the following protruding impression determination method.

  FIG. 7 is an explanatory diagram showing a method for determining an overhang imprint relating to the first embodiment. In the figure, C indicates a circular imprint. The protruding imprint determination unit 24 reads that the imprint is circular, and calculates the coordinate position of the imprint center position Q by image processing. As a method of determining the imprint center position Q, for example, in the case of a circular imprint, perpendicular lines are drawn from two different points on the outer frame of the imprint, and the lengths of the vertical lines from the intersection of the vertical lines to the outer frame of the imprint are equal. Centered on the intersection. If the seal is oval, the point where the outer frame curvature is the hardest and the loosest point are detected, a perpendicular line is drawn from the two points, and the intersection of the perpendiculars is the center. If the seal is a square, the intersection of the diagonal lines is the center. The method for determining the imprint center position Q may be performed using a known technique in addition to the above.

  Further, the protruding impression determination unit 24 calculates the width d and height h of the impression C by image processing. Thereby, the protruding impression determination unit 24 can calculate the protruding amount S. If S> 0, it is determined that the imprint C is a protruding imprint. In the case where the imprint C is an oval or square shape, similarly, the coordinate position of the imprint center position Q is calculated, the width d and the height h of the imprint C are calculated, and then the protrusion amount S is calculated. Furthermore, when the seal imprint C is oval and the stamp has an inclination, the protrusion is determined after the inclination is corrected.

  In addition to the method for calculating the protrusion amount S by calculating the coordinate position of the seal stamp center position Q as described above to determine the protrusion, for example, when the stamp is circular or oval, the shape of the stamp is not If the imprint can be discriminated to the extent that it can be estimated whether it is circular or oval from the frame, the outer frame that matches the outer frame of the extracted registered imprint candidate is estimated, and the estimated outer frame and the extracted registered imprint candidate outer frame If they do not coincide with each other, it may be determined as an overhang mark. By doing so, it is possible to determine the protrusion of the seal without calculating the seal stamp center position Q.

Returning to FIG. 5, step 204 and subsequent steps will be described.
S204: In step 203, when the extracted registered imprint candidate is a protruding imprint and N <4, the extracted imprint candidate is excluded.
S205: The collation control unit 28 instructs the counter unit 25 to add 1 when the retry count is the initial value = 0. Then, the process proceeds to step 202. As shown in FIG. 6B, up to four seal impressions as candidates can be determined.

S206: In step 203, when the extracted registered imprint candidate is not a protruding imprint and N <4, the collation control unit 28 instructs the protruding imprint determining unit 24 to extract the candidate imprint as a registered imprint. Then, the registered seal storage unit 26 is instructed to store the registered seal stamp.
S207: Further, the collation control unit 28 instructs the collation imprint storage unit 27 to store the collation stamp D read by the direct scanner 13.

  Next, the collation of the registered stamp A and the stamped stamp D will be described. FIG. 8 is an explanatory diagram illustrating a seal collation screen according to the first embodiment. The registered seal image 32 acquired from the seal stamp server 5 by the sales office window terminal 10 includes the two seal images A and B as described above. As described above, it is determined by the protrusion determination that the seal imprint B is a protrusion imprint, and the seal B is excluded. Then, the registered stamp A remains in the registered stamp partial image 34. That is, the imprint A is determined to be the registered imprint A, and the registered imprint partial image 34 is stored in the registered imprint storage unit 26. On the other hand, a check target imprint partial image 31 is obtained from the form 8 read by the direct scanner 13, and the check target imprint D is included therein. Then, the check target imprint partial image 31 is stored in the check target imprint storage unit 27.

  The branch office terminal control unit 17 of the branch office counter terminal 10 controls the seal stamp verification unit 15 to instruct the display 11 to display the registered seal stamp partial image 34 and the target seal stamp partial image 31. Here, the registered imprint A of the registered imprinted partial image 34 and the verified imprint D of the verified imprinted partial image 31 may be displayed side by side or displayed in an overlapping manner. When the registered seal A and the check target stamp D are displayed side by side, the person in charge performs seal verification visually. When the registered seal stamp A and the check stamp seal D are displayed in an overlapping manner, the store terminal control unit 17 instructs the display 11 to display different portions with different shapes. The figure shows that the portion of the registered imprint A and the collated imprint D that are different in shape from the imprint E displayed by superimposing the registered imprint A and the collated imprint D is a different display E-1. Thereby, the person in charge can perform seal stamp collation of the registered stamp A and the stamped stamp D.

  As described above, according to the first embodiment, when there are a plurality of imprints A and B in the registered imprint image 32 stored in the seal stamp server 5, the protruding imprint B can be determined from the registered imprint image 32. By automatically extracting the target registered seal A from the seal stamps A and B, it is possible to easily perform the matching operation between the registered seal A and the check target stamp D. Furthermore, the determination of the protruding impression B is possible by simple image processing.

  In the present embodiment, it is described that it is determined whether or not the number N of extractions is N <4. However, an arbitrary reference value may be set in advance, and the present invention is not limited to the number 4. Also, the seal stamp verification unit 15 is provided with a registered seal candidate number determination unit 43, which will be described later in the second embodiment, and the result of counting the number of registered seal candidates from the registered seal image 32 prior to the extraction of the registered seal candidate is represented by M. As a result, the process of S203 may be performed with N <M. In this case, for example, if there are two imprints in the registered imprint image 32 as shown in FIG. 6A, N <2 and in the case shown in FIG. 6B, N <4.

  Further, in the present embodiment, the description has been made on the assumption that a plurality of imprints are included in the registered imprint image 32. However, when only one imprint is included in the registered imprint image 32, the protruding imprint is displayed. It is also possible to perform the processing after S104 immediately without making the determination.

<Second Embodiment>
FIG. 9 is a block diagram showing a configuration of the sales office window terminal 50 according to the second embodiment. The sales office window terminal 50 as a seal verification device includes a display 11 as a display unit, a mouse / keyboard 12 as an input unit, a direct scanner 13, a communication printer 14, a seal verification unit 55, and a terminal storage unit. 16 mag. Among these, the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted. The second embodiment is further different from the first embodiment in having a specific character storage unit 51.

  The specific character storage unit 51 stores a character to be detected in order to detect a specific character from the character image included in the registered seal image 62 read from the seal stamp server 5. The specific characters are “notification”, “validation”, and “verification”, which will be described later. These specific characters are read from the specific character storage unit 51 under the control of the branch terminal control unit 57. Then, the same character as the specific character is detected from the registered seal image 62 by the character detection unit 44 of the seal collation unit 55 described below.

  FIG. 10 is a functional block diagram of the seal collation unit 55 relating to the second embodiment. The registered seal image storage unit 41 stores a registered seal image 62 obtained from the seal server 5 for stamp verification. The registered seal image 62 includes a registered seal and seals other than the registered seal. The registered imprint candidate extraction unit 42 extracts candidate imprints A, F, and G that are registered imprint candidates from the registered imprint image 62 stored in the registered imprint image storage unit 41, and calculates the position thereof. The registered imprint candidate number determination unit 43 determines the number of candidate imprints A, F, and G that are registered imprint candidates extracted by the registered imprint candidate extraction unit 42.

  Further, the character detection unit 44 detects a specific character such as “notification seal” stored in the specific character storage unit 51 from the character image included in the registered seal image 62 read out from the seal stamp server 5. The position is calculated. The distance calculation unit 45 calculates the distance between the specific character position detected by the character detection unit 44 and the positions of the candidate impressions A, F, and G. The upgrade / downgrade processing unit 46 selects a registered seal by performing an upgrade / downgrade process for each candidate seal in accordance with the distance between the specific character calculated by the distance calculator 45 and the candidate seal. The registered seal storage unit 47 stores the registered seal A that has been upgraded by the upgrade / downgrade processing unit 46 from the candidate seals A, F, and G, that is, finally determined. The check target imprint storage unit 48 stores the check target seal D read by the direct scanner 13 of the sales office window terminal 50. And the collation control part 49 controls each part in the seal stamp collation part 55. FIG.

FIG. 11 is a flowchart of the registered seal extraction process relating to the second embodiment.
S301: Upon receiving the registered seal image 62 from the seal stamp server 5, the verification controller 49 of the seal stamp verification unit 55 instructs the registered seal image storage unit 41 to store the registered seal image 62.
S302: The collation control unit 49 instructs the registered imprint candidate extraction unit 42 to extract one or more imprints in the registered imprint image 62 stored in the registered imprint image storage unit 41.

  S303: The collation control unit 49 instructs the registered imprint candidate number determination unit 43 to determine the number of candidate imprints extracted by the registered imprint candidate extraction unit 42. If the number is one, the process proceeds to step 307, and if there is a plurality, the process proceeds to step 304.

  Here, the upgrade / downgrade process performed by the upgrade / downgrade processing unit 46 according to the distance between the position of the specific character and the position of the candidate seal impression will be described. First, FIG. 12 is an explanatory view showing the seal and characters of the registered seal image 62 relating to the second embodiment. The registered seal image 62 is a part of an image obtained by reading an application form for opening an account (not shown). A plurality of ruled lines 63 are displayed on the application form for opening an account, and a description column surrounded by the plurality of ruled lines is formed.

  A character 64 of “notification stamp” as a specific character is a character indicating a position where the registration mark is imprinted, and is printed in advance in the notification stamp imprint field 65. In the notification seal stamp field 65, a seal A of the notification seal is displayed. Further, a “66” character 66 as a specific character is a character indicating a position where the seal is to be stamped, and is printed in advance in the seal stamp field 67. The seal stamp field 67 displays a seal stamp F of the seal. Furthermore, the “marking” character 68 as the specific character is a character indicating a position where the marking is to be stamped, and is printed in advance in the marking stamping column 69. In the seal stamp field 69, a seal impression G of the seal is displayed.

  FIG. 13 is an explanatory diagram showing the distance between the specific character and the seal stamp related to the second embodiment. The figure shows the positions of the character 64 of “notification”, the character 66 of “signature”, and the character 68 of “verification”, the center AQ of the imprint A, the center FQ of the imprint F, and the center GQ of the imprint G. Indicates that the distance to each position is calculated. A line segment indicated by a broken line indicates that the upgrade / downgrade process is not performed because it is outside a certain distance. Furthermore, a line segment indicated by a solid line indicates that the upgrade / downgrade process is performed because it is within a certain distance. That is, the upgrade / downgrade process is performed between the letter 64 of “notification” and the center AQ of the seal A, between the character 66 of the “signature” and the center FQ of the seal F, and the center of the character 68 of the “signature” and the seal G. It is determined according to the distance between GQ. That is, as a result of the upgrade / downgrade process, an imprint A that is within a certain distance from the letter 64 of “notification” is upgraded. Then, the imprint F within a certain distance from the “mark” 66 and the imprint G within a certain distance from the “mark” 68 are downgraded. By doing so, the imprint A immediately below the character 64 of “notification” can be finally extracted as a registered imprint.

Returning to FIG. 11, step 304 and subsequent steps will be described.
S304: In step 303, when there are a plurality of registered imprint candidate numbers determined by the registered imprint candidate number determination unit 43, the collation control unit 49 instructs the character detection unit 44 about the specific character read from the specific character storage unit 51. Instruct to detect from the registered seal image 62. The specific characters are “notification”, “signature”, and “validation” used in the application form at the time of opening an account. When the character used in the application form at the time of opening an account differs depending on the financial institution, the specific character to be detected is a character matched to that. The character detection unit 44 stores the position of the detected specific character in the registered seal image 62 as an image.

  S305: The collation control unit 49 instructs the distance calculation unit 45 to calculate the distance between the position of each specific character and a plurality of impressions. This distance is determined by the positions of the character 64 of “notification”, the character 66 of “signature”, and the character 68 of “verification” explained in FIG. 10, the center AQ of the imprint A, the center FQ of the imprint F, and the imprint. It is the distance between each position of the center GQ of G.

  S306: The collation control unit 49 instructs the upgrade / downgrade processing unit 46 to perform the upgrade / downgrade process for the distance calculated by the distance calculation unit 45. As described with reference to FIG. 10, the upgrade / downgrade processing unit 46 upgrades the space between the letter 64 of “notification” and the center AQ of the seal imprint A. Thereby, the collation control unit 49 determines that the seal A is a registered seal.

S307: The collation control unit 49 instructs the registered stamp storage unit 47 to store the stamp A as a registered stamp.
S308: Further, the collation control unit 49 instructs the collated imprint storage unit 48 to store the collated imprint D read by the direct scanner 13. The collation of the last registered seal A and the collated seal D is the same as that in the first embodiment, and thus the description thereof is omitted.

  As described above, according to the second embodiment, when there is a seal or a seal other than the registered seal in the registered seal image 62, a specific character such as “notification” is detected, and the specific character and the seal are detected. Since the registered imprint A is determined according to the distance between the registered imprint A, the desired registered imprint A from the plural imprints A, F, G, Can be easily performed. Since the determination of the registered seal is performed by the upgrade / downgrade process according to the distance between the specific character and the seal, there is an effect that the registered seal can be easily determined.
