Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
First, the configuration in the present embodiment will be described.

  FIG. 1 shows the overall configuration of an ID card creation system 100 in an embodiment to which the present invention is applied. As shown in FIG. 1, the ID card creation system 100 includes a host 1, a file server 2, a registration device 3, a photographing device 4, and an ID card creation device 5, and these devices are connected via a communication network N. Connected to each other. Here, the communication network N is a communication network constructed using a dedicated line, and various line forms such as a LAN (Local Area Network) and a WAN (Wide Area Network) can be applied.

  The number of registration devices 3 connected to one host 1 via the communication network N, the number of photographing devices 4, and the number of ID card creation devices 5 are not particularly limited.

  In the following, the ID card creation system 100 will be mainly described assuming that an ID card (employment (employee) certification card, etc.) of an employee belonging to an organization such as a company is created. It may be possessed by an organization that manages and supervises predetermined qualifications.

  The host 1 is connected to the file server 2, the registration device 3, the photographing device 4, and the ID card creation device 5 through the communication network N, and includes a DB (Data Base) 1 a. The DB 1a stores the ID number and personal information (name, address, affiliation, date of birth, etc.) of each employee. The host 1 controls updating and reading of information stored in the DB 1a.

  The file server 2 is constituted by, for example, a PC (Personal Computer) or the like, and is composed of each employee's ID number, face image data, personal information (name, address, affiliation, date of birth, etc.), and application form image data. A DB for storing files is provided. When the personal information of the ID card applicant (employee) is changed (when the ID card is updated), the file server 2 sends the applicant information file (ID number, face) transmitted from the photographing device 4 Image data, personal information, and application form image data) are stored in the DB. That is, the file server 2 stores the latest information for creating an ID car, and has a function as a spare DB when the DB 1a of the host 1 is down. Further, since the file server 2 has face image data and application form image data, it may be used for identity verification.

  The registration device 3 is composed of a PC (Personal Computer) or the like, and receives personal information (name, address, affiliation, age, gender, etc.) of the ID card registration applicant input using an input device such as a keyboard or a mouse. By sending it to the host 1, it requests ID card membership registration.

  The imaging device 4 acquires the face image data by capturing the face of the applicant in order to create an ID card. In addition, when the ID card is updated, the photographing apparatus 4 reads an update application form using the OCR unit 22 and the image scanner 23a (see FIGS. 2 and 3), and an information file (FIG. 5) is obtained from the read result and the applicant's face image data. And the created information file is transmitted to the file server 2 (see FIG. 4). Details of the photographing apparatus 4 will be described later with reference to FIGS.

  The ID card creation device 5 receives print data necessary for creating an ID card from the photographing device 4 and prints the print data on the surface of the ID card to create an ID card.

  FIG. 2 shows a side internal perspective view of the photographing apparatus 4. As shown in FIG. 2, the photographing device 4 includes a reading unit 20 and a device control unit 40 having a built-in video camera 41 for photographing a face image of the applicant.

  In the upper part of the reading unit 20, there are provided an insertion port 21 for an application form α and an input enabling lamp 26 a for displaying the application permission state of the application form α. The input-possible lamp 26a is turned on when the application form α is ready for input, and is turned off when the application form α is not ready for input.

  As shown in FIG. 2, the application form α includes personal information such as the applicant's address, name, date of birth, and ID number. When the application form α is input from the input port 21 in a reading direction, the application form α is transported vertically downward along the transport path by transport means such as a transport roller. An OCR unit 22 serving as a character recognition device of the present invention and a scanner unit 23 including an image scanner 23a are provided on a conveyance path for conveying the application form α downward in the vertical direction. An application bucket 24 is provided for storing an application conveyed from the section 23.

  The OCR unit 22 optically reads the ID number described in the application form α and recognizes the character as the ID number. After being read by the OCR unit 22, the application form α is conveyed to the scanner unit 23 provided downstream in the conveyance direction.

  The scanner unit 23 optically reads the contents of the application form α by the image scanner 23a and acquires application form image data. After reading by the scanner unit 23, the application form α is transported to the application form bucket 24 provided downstream in the transport direction, and sequentially stored.

  FIG. 3 shows an internal configuration of the photographing apparatus 4. The imaging device 4 includes a reading unit 20 and a device control unit 40 as shown in FIG.

  As shown in FIG. 3, the reading unit 20 includes a prevention pin driving unit 25, a notification unit 26, a roller driving unit 27, an application form presence / absence sensor 28, an OCR unit 22, and a scanner unit 23.

  The prevention pin drive unit 25 drives the prevention pin 25b as a conveyance prevention unit in accordance with a control signal input from the CPU 44 of the device control unit 40. Specifically, when the reading of the application form α is instructed by operating the operation unit 42, the prevention pin driving unit 25 resists the pressing force of the prevention pin 25b inserted on the conveyance path with a pressing force. As shown in FIG. When the application form α is inserted into the insertion slot 21, the application form α is conveyed by the control of the roller drive unit 27. At this time, the prevention pin drive unit 25 releases the tensile force applied to the prevention pin 25b. As a result, the application form α being conveyed is pressed in the direction B. Therefore, the application form α is conveyed while being pressed by the prevention pin 25b, and at the moment when the application form α has passed through the prevention pin 25b, the prevention pin 25b is inserted into the conveyance path and the next application form α is inserted. Stop.

  The notification unit 26 includes a throwable lamp 26a (refer to FIG. 2) for displaying a loading permission state of the application form α. The throwable lamp 26 a is configured by an LED (Light Emitting Diode) or the like, and is turned on or off according to a control signal input from the CPU 44. The input-possible lamp 26a is turned on when the application form α is ready for input, and is turned off when the application form α is not ready for input.

  The roller drive unit 27 includes a transport roller group 27a, and rotationally drives the transport roller group 27a in accordance with a control signal input from the CPU 44 to transport the application form α on the transport path.

  As shown in FIG. 2, the application form presence / absence sensor 28 is provided on the conveyance path below the OCR unit 22, detects an application form α conveyed from the OCR unit 22 to the scanner unit 23, and sends a detection signal to the CPU 44. Output. For example, the application form presence / absence sensor 28 detects the absence of the application form α and outputs a detection signal to the CPU 44 when the application form α being transported passes through the application form presence / absence sensor 28. Receiving the detection signal indicating the absence state of the application form α, the CPU 44 instructs the prevention pin driving unit 25 to drive the prevention pin 25b in the B direction. As a result, the application of the next application form α is permitted.

  The OCR unit 22 optically reads the ID number described in the application form α, recognizes characters from the image data obtained by the reading, and determines the text code data of the recognized ID number in the device control unit 40 Output to the unit 52 and the file editing control unit 45.

  The scanner unit 23 includes an image scanner 23a and a memory 23b. The image scanner 23a optically reads the contents of the application form α, acquires application form image data, and outputs the acquired image data to the memory 23b. The memory 23b stores application form image data input from the image scanner 23a.

  The apparatus control unit 40 includes a CPU (Central Processing Unit) 44, an operation unit 42, an image data compression unit 46, a front / back discrimination unit 48, a threshold memory 48a, a recognition unit 51, a discrimination unit 52, a file editing control unit 45, and a video camera 41. , A communication control unit 49, a display unit 50, and a memory 47.

The CPU 44 comprehensively controls each unit of the reading unit 20 and the device control unit 40.
The operation unit 42 includes a keyboard including cursor keys, numeric input keys, and various function keys, and outputs an operation signal generated by pressing the keyboard to the CPU 44. The operation unit 42 may include other input devices such as a mouse and a touch panel.

  The image data compression unit 46 compresses the application form image data stored in the memory 23a of the scanner unit 23 based on, for example, the run length of white or black pixels by the MMR method, and the compressed image. Data is output to the file editing control unit 45.

  The front / back discrimination unit 48 counts the information amount of the application form image data compressed by the image data compression unit 46, and compares it with the threshold value stored in advance in the threshold memory 48a, thereby discriminating the front / back side of the application form α. The determination result is output to the CPU 44. This threshold is a value set by the amount of image information for forming the predetermined form of the application form α. That is, in the application form α, personal information, ID number, etc. are printed on a predetermined form (for example, ruled lines for forming a plurality of item fields, address entry fields and name entry fields). Therefore, if the threshold value is set based on the information amount of the image data forming the form, the front and back of the application form α can be clearly determined. Actually, since the amount of information of the image data varies even in the same application form α, the threshold is preferably set slightly larger than the amount of information of the image information forming the form.

  The recognition unit 51 cuts out the applicant's ID number from the application form image data stored in the memory 23b, performs character recognition of the ID number based on the cut out image data, and sends the character recognition result to the determination unit 52. Output.

  The determination unit 52 determines the consistency of the applicant's ID number by comparing the ID number of the applicant whose character has been recognized by the OCR unit 22 with the ID number whose character has been recognized by the recognition unit 51. The result is output to the file editing control unit 45. The file server 2 may include a recognition unit 51 and a determination unit 52. In this case, the file server 2 discriminates the consistency between the ID number of the information file and the ID number that is extracted from the application form image data and recognized as a character, and if they do not match, issues a warning and Do not file application image data.

  The file edit control unit 45 validates the application form image data input from the image data compression unit 46 only when the front / back discrimination unit 48 determines that the front side of the application form α has been read. The ID number recognized by the recognition unit 51 is added to the header of the application form image data compressed by the image data compression unit 46.

  The file editing control unit 45 also includes an ID number recognized by the OCR unit 22, the applicant's face image data acquired from the video camera 41, the applicant's personal information acquired from the host 1, The application form image data with the ID number added to the header is synthesized to create an information file (see FIG. 5), and the created information file is output to the memory 47.

  If the file editing control unit 45 determines that the ID number of the applicant recognized by the OCR unit 22 matches the ID number recognized by the recognition unit 51 by the determination unit 52, the ID number Is used as a search key to read the corresponding information file from the memory 47 and instruct the communication control unit 49 to send the read information file to the file server 2.

  The video camera 41 includes an optical lens made of glass or plastic, an optical sensor such as a CCD (Charge Coupled Device) or a CMOS (Complementary Metal Oxide Semiconductor), and an image input through the optical lens is converted into an electrical signal by the optical sensor. To obtain an image signal.

  The communication control unit 49 is an interface connectable to a transmission medium connected to a communication network N such as a LAN or WAN, and performs control for communicating with an external device via the communication network N.

  The display unit 50 includes a display screen such as a CRT (Cathode Ray Tube) or an LCD (Liquid Crystal Display), and displays required display data on the display screen in accordance with a display control signal input from the CPU 44.

Next, the operation in this embodiment will be described.
With reference to the flowchart of FIG. 4, information file creation processing executed in the photographing apparatus 4 will be described.

  When the application form α is inserted into the insertion slot 21 when the ID card is updated, the ID number written in the application form α is read and character-recognized by the OCR unit 22, and the character-recognized ID number is stored in the information file. (Step S1). The application form α that has been read by the OCR unit 22 is conveyed to the scanner unit 23. When the ID number is stored as an information file in step S1, the face image of the applicant is photographed by the video camera 41, and the face image data obtained by photographing is stored as an information file in association with the ID number (step S1). S2).

  When the ID number is stored as an information file in step S1, the description content of the application form α is read by the image scanner 23a in parallel with the process of step S2, and the image data of the application form α is acquired ( Step S3). Then, the ID number portion is cut out from the application form image data acquired in step S3, and the ID number is character-recognized from the cut out image data (step S4).

  Next, the ID number recognized in step S4 is stored in the header portion of the application form image data acquired in step S3 (step S5), and the application form image data is identified by the ID number (step S1). It is stored as an information file in association with the ID number recognized by the OCR unit 22 (step S6).

  In parallel with the processing of steps S2 to S6, corresponding personal information is acquired from the DB 1a via the communication network N using the ID number recognized in step S1 as a search key, and the acquired personal information is acquired. Is stored in association with the corresponding ID number as an information file, thereby creating an information file M as shown in FIG. As shown in FIG. 5, the information file M is a file in which an ID number, personal information, face image data, and application form image data are combined.

  Next, the ID number stored in the information file M and the ID number stored in the header of the application form image data of the information file M are compared (step S7), and the consistency of the ID number is determined (step S8). .

  If it is determined in step S8 that the ID numbers do not match (step S8; NO), an error process is performed (step S10), and the information file creation process ends. In the error processing in step S10, for example, the display unit 50 displays that the ID numbers do not match. If it is determined in step S8 that the ID numbers match (step S8; YES), the created information file M is sent to the file server 2 via the communication network N (step S9), and this information file creation process is performed. Ends.

  As described above, according to the ID card creation system 100 of the present embodiment, the description content of the same application is read by the OCR unit 22 and the image scanner 23a, and the ID number of the applicant recognized by the OCR unit 22 and The applicant's ID number is erroneously recognized by comparing the applicant's ID number acquired from the image scanner 23a and recognized by the recognition unit 51, and determining the consistency of the applicant's ID number. The reliability of the ID card creation system 100 can be improved.

  Note that the description in the present embodiment can be changed as appropriate without departing from the spirit of the present invention.

  For example, in the present embodiment, the information file M having the data structure as shown in FIG. 5 is sent to the file server 2. However, as shown in FIG. If the mode information indicating the form is added, the file server 2 that receives the information file can determine the form of the received information file.

  FIG. 6 shows the data structure of an information file in three modes (mode 1, mode 2, and mode 3) as an example of the form of the information file. The mode 1 information file M1 includes an ID number, face image data, personal information, and mode information. Data representing mode 1 is stored in the “mode information” of the information file M1. For example, when it is not necessary to read the application form, the information file M1 is sent from the imaging device 4 to the file server 2.

  Mode 2 has two information files M21 and M22 for the same ID number, and each information file is sent to the file server 2 at different timings. The information file M21 includes an ID number, face image data, personal information, and mode information. The information file M22 includes an ID number, application form data, personal information, and mode information. Data representing mode 2 is stored in the “mode information” of the information files M21 and M22.

  For example, when the image scanner 23a is out of order, first, an information file M21 that does not include the application form image data is sent to the file server 2, and after the image scanner 23a is restored, the description contents of the corresponding application form are displayed. The application form image data is obtained by reading. Then, an information file M22 is created and sent to the file server 2. When the video camera 41 is out of order, first, an information file M22 that does not include face image data is sent to the file server 2, and after the video camera 41 is restored, a face image is taken and the information file M21 is captured. Is created and sent to the file server 2.

  The mode 3 information file M3 includes an ID number, application data, personal information, and mode information. Data representing mode 3 is stored in “mode information” of the information file M3. When it is not necessary to shoot a face image, the information file M3 is sent from the photographic device 4 to the file server 2.

  FIG. 7 shows a main configuration of the file server 2 that receives the information file. As shown in FIG. 7, the file server 2 includes a communication control unit 201, a memory 202, and an editing unit 203.

  The communication control unit 201 performs control for communicating with an external device via the communication network N. The memory 202 temporarily stores the received information file. The editing unit 203 determines mode information of the received information file. When the mode information of the received information file is mode 1 or mode 3, the editing unit 203 considers that the information file has no missing data, and stores the information file in the DB 204. On the other hand, when the mode information of the received information file is mode 2 (for example, when the information file M21 is received), the editing unit 203 temporarily stores the information file in the memory 202 and is included in the information file. It waits for reception of the same information file (information file M22) as the ID number and mode information. When the corresponding information file (information file M22) is received, the editing unit 203 combines the information files M21 and M22, and stores the combined information file in the DB 204. Alternatively, the face image and the application form image data are separately stored in association with the same ID number.

  As described above, even when a failure or the like occurs in the photographing apparatus 4 and missing data occurs in the created information file, the mode information indicating the form of the file is added to the information file, so that the file server 2 can obtain the mode information. From the above, it is determined whether or not there is missing data in the received information file, and if there is missing data, it waits for the reception of the information file containing the missing data. Only information files can be stored in the DB 204. Therefore, even if a failure occurs in the photographing device 4, the file server 2 stores the correct information file, so that the reliability of the ID card creation system 100 can be improved.

  In the above-described embodiment, the case where the face image of the renewal applicant is directly taken by the video camera 41 when the ID card is renewed has been shown. However, as shown in FIG. In the case of using the application form β, it may be possible to perform copy photography for photographing the face photograph P on the application form β. As shown in FIG. 8, the photographing apparatus 4a capable of such copying and photographing is provided with an electronic camera 30 such as a digital camera between the OCR section 22 and the scanner section 23, and is attached to the application form β. The face image data can be obtained by taking the face photograph P with the electronic camera 30.
