  Further, when, for example, a shooting prohibition mark <2> is detected from the image data captured by the digital camera device 10 as a subject to be photographed, the captured data is stored in the image memory 14b. It is deleted (destroyed) without being saved.

  Further, when, for example, a charging mark (<1> <3>, etc.) is detected from the image data captured by the digital camera device 10, the camera ID and the charging information corresponding to the detection mark are stored in the store. The side ECR 30 is notified by radio and stored in the billing information memory 32a. Then, when the camera ID is input in the store-side ECR 30, each charging information associated with the input camera ID and stored in the charging information memory 32a is read and added as a cash register amount, and the corresponding camera user Is presented (displayed) to be settled.

  This not only monitors the camera shutter sound in the store, but also performs control that prohibits imaging for each part that can be taken, such as for each book, page, article, etc. I can prevent illegal shooting such as digital shoplifting.

  Next, a detailed operation of the illegal photographing prevention system including the digital camera device 10 and the store-side ECR 30 according to the configuration of the second embodiment will be described.

  FIG. 10 is a flowchart showing an illegal shooting prevention function by the illegal shooting prevention system. FIG. 10A is a flowchart showing the digital camera process, and FIG. 10B is a flowchart showing the store-side ECR charging process. is there.

  First, in the digital camera device 10, for example, when photographing prohibition control or billing control is desired at a book store, a book photographing mode is set in advance by operating the input unit 16.

  When the shutter operation of the input unit 16 is determined in the digital camera device 10 (step A1), it is determined whether or not the mode data of the book shooting mode is stored and set in the shooting mode memory 13A in the RAM 13 (step A1). A2).

  In this step A2, if it is determined that the shooting mode memory 13A in the RAM 13 is not set to store the mode data of the book shooting mode and is in the other normal shooting mode (step A2 (NO)), the sound is recorded. A shutter sound is generated and generated by the generation unit 17 (step A3), and image data of the subject imaged by the imaging unit 14 in accordance with the shutter operation is stored and saved in the image memory 14b and subjected to normal photographing processing ( Step A4).

  In addition, when the normal photography process in the state which does not set the book photography mode by this digital camera apparatus 10 is performed in the book store provided with the illegal photography prevention system of this embodiment, the digital camera apparatus 10 The generated shutter sound is input to and detected by the audio input unit 34 of the store side ECR 30 (step B1).

  In this case, in the store-side ECR 30, the report sound unit 36 reports that there is a possibility that illegal shooting is being performed in the store by a voice message or the like, and notifies the store owner (step B2). ).

  As a result, for example, at a book store, camera shutter sound in the store can be constantly monitored, and it is possible to carefully prevent books and the like from being taken illegally by customers.

  On the other hand, when it is determined that the book shooting mode mode data is stored in the shooting mode memory 13A in the RAM 13 in accordance with the shutter operation by the digital camera device 10 (step A2 (YES)), On the other hand, special light (invisible light such as infrared light or ultraviolet light) is irradiated by the light irradiation unit 14a (step A5), and image data captured by the imaging unit 14 in the irradiation state of the special light is obtained. Analysis processing is performed (steps A6 and A7).

  A plurality of types of marks <1> and <2> stored and managed in the mark management information memory 13B (see FIGS. 6 and 7) in the storage device 12 in the image data being picked up by the image pickup unit 14. It is determined whether or not any of the above is detected (step A8).

  Here, when the subject by the digital camera device 10 is a page of a book, and the shooting prohibition mark <2> is detected from the image data being captured as shown in FIG. 7B, for example. (Step A9 (YES)), after the image data corresponding to the detected portion of the photographing prohibition mark <2> is deleted (discarded) in the image data (Step A10), the mark <2> does not exist. The image data of the part imaged is stored and saved in the image memory 14b (step A13).

  Thereby, for example, taking-out of a page of a book can be prohibited for a partial area in the page, and illegal shooting of a book page by a customer can be prevented. When the photographing prohibition mark <2> is detected from the entire captured book page, the entire page image data corresponding to this mark is deleted (discarded), so that the image memory 14b stores Virtually no image data is stored and saved.

  On the other hand, in step A8, the subject by the digital camera device 10 is a book page, and a charging mark <1> is detected from the image data being picked up as shown in FIG. 7A, for example. (Step A9 → A11 (YES)), the charging information stored and managed in the mark management information memory 13B in association with the charging mark <1> together with the camera ID stored in the storage device 12 (A publication / billing 10 yen) is read and transmitted from the communication control unit 19 to the store-side ECR 30 (step A12).

  Then, only the image data (in this case, the mark <1>) imaged in accordance with the irradiation of the special light (invisible light) is deleted from the image data being captured (step A13), The captured image data after the deletion of the mark <1> is stored and saved in the image memory 14b (step A14).

  When the store-side ECR 30 receives the charging information <A> for charging mark <1> with the camera ID transmitted from the digital camera device 10 (A publication / billing 10 yen) (step B3), the received information is received. The billing information is stored in the billing information memory 32a in the storage device 32 together with the camera ID (step B4).

  Further, another subject by the same digital camera device 10 in the same store after that is a page of another book. For example, as shown in FIG. When the mark <3> is detected (step A8 → A9 → A11 (YES)), the mark management information memory 13B is associated with the charging mark <3> together with the camera ID stored in the storage device 12. The billing information (Mr. B / billing 5 yen) stored and managed is read out and transmitted from the communication control unit 19 to the store-side ECR 30 (step A12).

  Then, only the image data (in this case, mark <3>) imaged in accordance with the irradiation of the special light (invisible light) is deleted from the image data being imaged (step A13), The captured image data after the deletion of the mark <3> is stored and saved in the image memory 14b (step A14).

  When the store side ECR 30 receives the charging information <Mr. B / Billing 5 Yen> corresponding to the charging mark <3> with the camera ID transmitted from the digital camera device 10 (step B3), this received The billing information is additionally stored in the billing information memory 32a in the storage device 32 together with the camera ID (step B4).

  Then, in the registering process by the store-side ECR 30 when the user of the digital camera device 10 leaves the store (step B5), when the camera ID of the user-owned digital camera device 10 is input by the input unit 33 (step B6). Each billing information associated with the camera ID and stored in the billing information memory 32a in the storage device 32 (in this case, “A publication / billing 10 yen” and “Mr. B / billing 5 yen”) The accumulated total amount (15 yen) is displayed on the display unit 35 as the cash register amount (step B7).

  Thus, for example, when photographing a page of a book by the digital camera device 10, the charging control marks <1>, <3>,... Printed on the necessary portion of the page with the special ink are detected. The billing information corresponding to the detection mark is transmitted to the store ECR 30 together with the camera ID, and the cash register amount is calculated and presented from the corresponding billing information by the input of the camera ID at the time of cash register processing. It is possible to charge the whole page or a part of the page without taking out the camera without taking out the payment, and it is possible to prevent illegal photographing of the books sold by the customer.

  FIG. 11 is a flowchart showing a billing totaling process by the store-side ECR 30 of the illegal photographing prevention system.

  This accounting totaling process is started every time the current date and time updated and stored in the timing memory 32c of the storage device 32 reaches the end of the month (step C1), and is stored in the accounting information memory 32a. Each billing information is read out, and the billing amount is accumulated and displayed on the display unit 35 for each publisher and author who is the payee of each billing information.

  As a result, in the store-side ECR 30 equipped with the illegal photographing prevention system, the amount of billing according to the photographing of the books sold by the digital camera devices 10 of a plurality of customers in the store obtained in one month of the month is obtained. The payment is automatically counted for each payee, and the payment process can be easily performed.
