Description

  The present invention relates to a camera photographing prohibition system, and more particularly to a camera photographing prohibition system that automatically prohibits a photographing operation by a mobile phone or the like equipped with a camera function in a photographing prohibited area.

  In recent years, mobile phones have become more and more multifunctional, and now mobile phones equipped with camera functions have become widespread. However, with the widespread use of mobile phones equipped with this camera function, problems such as voyeurism of books and publications at bookstores and the like by such mobile phones have occurred and are frequently reported in newspapers and news. In addition, problems such as voyeurism of secret matters in corporate development departments and research institutes are also increasing within companies. For this reason, countermeasures such as sounding the shutter sound are taken, and companies and the like have established a prohibited area for bringing mobile phones with cameras, etc. due to security measures, and temporarily leave the mobile phone when entering the prohibited area. It is difficult to completely control voyeurism. Under such circumstances, the mobile phone itself is required to have a function of recognizing the camera photographing prohibited area and automatically restraining the photographing.

  Therefore, when it is desired to prohibit shooting of a certain shooting target object, the shooting prohibition signal transmitting device transmits a shooting prohibition signal to the vicinity of the shooting target object to be prohibited from shooting, and the mobile phone equipped with the camera function receives the shooting prohibition signal. Conventionally, a camera photographing prohibition system has been proposed in which a video acquisition operation by photographing is prohibited when an image is received (see, for example, Patent Document 1).

  In addition, a radio wave with a control signal is transmitted to the area where the person who enters the restricted space covers the area where the person who enters the restricted space passes inside the entrance / exit of the space where the shooting is to be restricted, and this control signal is received. For such mobile phones, a camera photographing prohibition system in which the photographing mode is changed to a photographing prohibition state is also conventionally known (for example, see Patent Document 2). According to this conventional camera photographing prohibition system, the photographing mode of the mobile phone is automatically prohibited in the restricted space.

Further, the photographing prohibited area B has a size within a normal infrared reach range narrower than that of the photographing prohibited area A. For example, the photographing prohibited area B is provided by taking advantage of its characteristics.

  As shown by 10a in FIG. 1, when the mobile phone 10 moves to a photographing prohibited area A, which is a radio zone of the photographing prohibited BTS 30, and performs camera photographing, the portable telephone 10 sends a broadcast channel (BCCH) of a specific frequency from the photographing prohibited BTS 30. The shutter key is invalidated when the shutter key is pressed at the time when the photographing prohibition message transmitted in (1) is received.

  Further, as shown by 10b in FIG. 1, when the mobile phone 10 moves to the photographing prohibited area B that is the infrared light transmission range of the photographing prohibited infrared device 40 and performs camera photographing, the photographing prohibited infrared device 40 is inquired and receives an infrared signal from the photographing prohibited infrared device 40 to know that it is a photographing prohibited area. Since the mobile phone (MS) 10 (10a, 10b) has a structure in which the photographing prohibited BTS 30 and the photographing prohibited infrared device 40 cannot be identified in advance, the BCCH scan of the photographing prohibited BTS 30 and the photographing prohibited infrared device 40 inquiries are made simultaneously.

  Next, the configuration of the mobile phone (MS) 10 in FIG. 1 will be described. FIG. 2 shows a block diagram of an embodiment of the mobile phone 10. In the figure, an operation unit 11 is connected to a display unit 12, a key input unit 13, an audio control unit 14, a camera control unit 15, and a sequence control unit 16, and has a determination function for comprehensively controlling the mobile phone 10.

Omitted.

  The wireless control unit 17 wirelessly communicates with the nearest wireless base station (BTS) including the imaging prohibited BTS 30, and the received signal is demodulated and supplied to the received data analyzing unit 18, for example. For example, the data is modulated and transmitted wirelessly. The data analyzed by the reception data analysis unit 18 is supplied to the sequence control unit 16. In addition, a transmission data creation instruction is output from the sequence control unit 16 to the transmission data creation unit 19. The infrared transmission / reception unit 1A transmits / receives infrared light signals to / from the photographing-inhibited infrared device 40. The received infrared light signals are photoelectrically converted and supplied to the infrared reception data analysis unit 1B for data analysis. On the other hand, the transmission data created by the infrared transmission data creation unit 1C is converted into an infrared light signal and transmitted. Each of the infrared reception data analysis unit 1B and the infrared transmission data creation unit 1C is connected to the sequence control unit 16.

  In the MS 10 having the above-described configuration, when the operation unit 11 recognizes that the shutter key in the camera control unit 15 is pressed, the operation unit 11 confirms with the sequence control unit 16 whether photographing is permitted. Thereby, in the sequence control part 16, the reception process of infrared rays and BCCH is started simultaneously. In response to the activation from the sequence control unit 16, the infrared transmission data creation unit 1C creates inquiry transmission data using infrared rays, and instructs the infrared transmission / reception unit 1A to transmit the transmission data, and also instructs reception. At the same time, a BCCH reception instruction is issued to the radio control unit 17. When the infrared data is received by the infrared transmission / reception unit 1A, the received data is sent to the infrared reception data analysis unit 1B to perform data analysis processing.

  Thereafter, analysis data from the infrared reception data analysis unit 1B is transferred to the sequence control unit 16 to notify the operation unit 11 of the photographing permission / prohibition state. Also, in the prohibition of photographing by BCCH reception, the radio signal received by the radio control unit 17 is supplied to the reception data analysis unit 18 where the received data is analyzed. The analyzed reception data is transferred to the sequence control unit 16 and notifies the operation unit 11 of the photographing prohibited state.

  Next, the configuration of the shooting prohibited BTS 30 in FIG. 1 will be described. FIG. 3 shows a block diagram of an embodiment of the photographing prohibited BTS. In the figure, the radiography prohibition BTS 30 modulates transmission data in the radio control unit 31 and transmits it to the radio section. That is, when the transmission position is determined by the sequence control unit 32, the transmission data creation unit 33 creates transmission data of the photographing prohibition message in the BCCH data format.

  The radio control unit 31 sets a specific frequency of BCCH, and the sequence control unit 32 notifies the radio control unit 31 of the transmission timing, so that the transmission data of the above-described photographing prohibition message is transmitted by radio using the BCCH. The transmission signal from the MS wirelessly received by the wireless control unit 31 is analyzed by the reception data analysis unit 34 and output to the sequence control unit 32.

  Next, the configuration of the photographing-prohibited infrared device 40 in FIG. 1 will be described. FIG. 4 shows a block diagram of an embodiment of the photographing-inhibited infrared device. In the figure, a radiography prohibition infrared device 40 receives phototransmission inquiry data transmitted from the MS in the form of an infrared light signal by a data transmission / reception unit 41, photoelectrically converts it, and supplies it to a reception data analysis unit 42. Then, the data content of the received data is analyzed. As a result of this analysis, when the data content of the received data is a request for photographing permission from the MS, the received data is passed to the sequence control unit 43.

  The sequence control unit 43 is notified from the user operation unit 44 of either the photographing prohibited state or the photographing permitted state. When the photographing prohibited state is notified, the transmission data creating unit 45 indicates that photographing is prohibited. Is generated and supplied to the data transmission / reception unit 41, from which it is transmitted in the form of an infrared light signal. On the other hand, the sequence control unit 43 causes the transmission data creation unit 45 to create a message indicating that the photographing is permitted when the user operation unit 44 notifies the photographing permission state, and sends the message via the data transmission / reception unit 41. And transmit it in the form of an infrared light signal.

  Next, regarding the operation of the present embodiment described with reference to FIGS. 1 to 4, the flowchart for explaining the operation of the photographing prohibited BTS in FIG. 5, the flowchart for explaining the operation of the photographing prohibited infrared device in FIG. 6, and the mobile phone in FIG. The operation will be described in detail with reference to the flowchart for explaining the operation.

  First, the operation of the photographing prohibition BTS 30 shown in FIGS. 1 and 3 will be described with reference to the flowchart of FIG. The imaging prohibition BTS 30 performs BCCH transmission frequency setting processing in order to transmit an imaging prohibition message on the downlink broadcast channel BCCH having a specific frequency (step S1 in FIG. 5). In this BCCH transmission frequency setting process, the sequence control unit 32 selects a BCCH transmission frequency in the radio control unit 31. Next, the transmission data creation unit 33 performs BCCH transmission data creation processing for constructing BCCH data (step S2 in FIG. 5), and then performs BCCH transmission timing retrieval processing for searching for a transmission position in the sequence control unit 32 (FIG. 5). 5 step S3).

  In the above-described BCCH transmission timing search process, an RSSI measurement process for measuring the received electric field level (RSSI) of a specific frequency selected as the BCCH is performed when determining the search position of the transmission position (step S4 in FIG. 5). As a result of the RSSI measurement process, the sequence control unit 32 determines whether or not the obtained measured RSSI value is smaller than a predetermined value determined in advance (step S5 in FIG. 5). If it is equal to or greater than the specified value, the process returns to step S3 to search for the transmission timing again, searches for the transmission position, and measures RSSI in step S4.

  On the other hand, if the sequence control unit 32 determines in step S5 that the RSSI measurement value has fallen below the specified value, the transmission data creation unit 33 creates a shooting prohibition message, and the shooting prohibition message is specified in step S1. A BCCH transmission process is performed in which the radio control unit 31 transmits the signal using the BCCH having the frequency of (step S6 in FIG. 5). In the BCCH transmission process in step S6, the photographing prohibition message is continuously transmitted on the BCCH. Only when the RSSI measurement value falls below the specified value, the radiography transmission of the photographing prohibition message created by the transmission data creation unit 33 is performed using BCCH in order to prevent interference with BCCH transmitted by other base stations. It is.

  Next, the operation of the photographing prohibited infrared device 40 shown in FIGS. 1 and 4 will be described with reference to the flowchart of FIG. First, the sequence control unit 43 of the photographing-inhibited infrared device 40 performs infrared data reception start processing for starting reception of photographing permission data from the camera-equipped mobile phone 10b (step S11 in FIG. 6). Subsequently, the sequence control unit 43 determines whether or not the data transmitting / receiving unit 41 in FIG. 4 has received data (step S12 in FIG. 6). If no data has been received, the sequence control unit 43 performs data determination again. If there is received data, the received data analysis unit 42 in FIG. 4 analyzes the received data to determine whether the received data is photographing permission data transmitted from the camera-equipped mobile phone 10b (step S13 in FIG. 6).

  If the received data is not photographing permission data as a result of the received data analysis, the operation is terminated. If the received data is photographing permission data, the sequence control processing of the sequence control unit 43 is performed (step S15 in FIG. 6), and then it is determined whether or not the photographing prohibition state is set in the sequence control unit 43 (FIG. 6). In step S16), when the photographing prohibition state is set, the transmission data creation unit 45 performs transmission data creation processing for creating a prohibition notification message (step S17 in FIG. 6), and the data transmission / reception unit 41 creates it. The prohibition notification message is transmitted to the camera-equipped mobile phone 10b in the form of an infrared light signal (step S19 in FIG. 6).

  On the other hand, when it is determined in step S16 that the photographing prohibition state is not set (when the operation state is determined to be released), transmission data generation processing for generating a permission notification message is performed in the transmission data generation unit 45. Thereafter (step S18 in FIG. 6), the created permission notification message is transmitted to the camera-equipped mobile phone 10b in the form of an infrared light signal by the data transmitter / receiver 41 (step S19 in FIG. 6).

  The camera-equipped mobile phone 10b receives the message of the above infrared light signal by the infrared transmission / reception unit 1A shown in FIG. 2, analyzes the message content of the received signal by the infrared reception data analysis unit 1B, and prohibits the message content. In the case of notification, the operation of exiting the camera mode is performed by canceling the pressing of the shutter key of the camera-equipped mobile phone 10b. On the other hand, if the message content is a permission notification, the camera-equipped mobile phone 10b continues to shoot as it is.

  Next, the operation of the camera-equipped mobile phone (MS) 10 shown in FIGS. 1 and 2 will be described with reference to the flowchart of FIG. First, when the user of the camera-equipped mobile phone (MS) 10 enters the camera mode state to perform camera shooting, the operation unit 11 in FIG. 2 determines whether the shutter key of the camera control unit 15 is pressed (in FIG. 7). Step S21). If it is determined in step S21 that the shutter key has been pressed, the operation unit 11 sends the frequency of the notification channel (BCCH) defined for photographing prohibition to the radio control unit 17 via the sequence control unit 16. A photographing prohibition BCCH frequency setting process to be set is performed (step S22 in FIG. 7).

  Subsequently, the operation unit 11 performs a BCCH reception start process in which the radio control unit 17 scans the radiographing prohibition BCCH set through the sequence control unit 16 and receives and acquires a message wirelessly transmitted on the BCCH (see FIG. 7 step S23). Subsequently, almost simultaneously with the BCCH reception start processing operation, the operation unit 11 performs an infrared data transmission process in which the permission inquiry message created by the infrared transmission data creation unit 1C is transmitted from the infrared transmission / reception unit 1A as an infrared light signal (FIG. 7 step S24).

  Subsequently, the photographing prohibition in response to the permission inquiry message transmitted in the infrared light by the infrared data transmission processing in the above step S24 is received. The operation unit 11 determines whether or not the ACK message can be received as an infrared signal (step S25 in FIG. 7).

  When the wirelessly transmitted message on the BCCH is received or the infrared light signal of the ACK message including the prohibition of photographing is received, the operation unit 11 in FIG. 2 controls the audio control unit 14 to generate an alarm sound. Next, a camera mode canceling process is performed (step S27 in FIG. 7), and the camera control unit 15 performs a camera mode release process that disables the pressing of the shutter key in the camera control unit 15 and prohibits shooting by the camera control unit 15 (step S27 in FIG. 7). Return to. The user can know that he / she has entered the prohibited shooting area by sounding the alarm sound. Note that a message indicating that photographing is not possible may be displayed on the display unit 12 because the alarm sound is sounded or instead of the sounding of the alarm sound, because the photographing unit is in the photographing prohibited area.

  On the other hand, when the operation unit 11 cannot receive the radio signal on the BCCH in step S25, or determines that the ACK message containing the permission for photographing is received with the infrared light signal, the operation unit 11 presses the shutter key. A photo shooting process is performed to validate and perform a normal shooting operation (step S28 in FIG. 7).

  As described above, according to the present embodiment, in addition to the method of prohibiting photographing using infrared rays, by improving the BTS, a BCCH is transmitted at a specific radio frequency, and the mobile phone 10 transmits the BCCH. Since the photographing is prohibited at the time of reception, the user of the mobile phone 10 recognizes that it is a photographing prohibited area, or the photographing is automatically prohibited, and the leakage of information in the company due to voyeurism is greatly reduced. Can do.

  In addition, only the method of prohibiting shooting using infrared rays has a limit in the range of prohibited shooting areas, and it may not be possible to set the area over a wide range or may be blocked by obstacles. Since the radio frequency BCCH is used to transmit an imaging prohibition message and the pressing of the shutter key is invalidated, it is possible to set an imaging prohibition area that is wider than infrared communication and less affected by obstacles. Further, even in an MS in which no infrared device is mounted, it is possible to limit shooting using a specific radio frequency BCCH.

  Note that the present invention is not limited to the above-described embodiment. For example, in the above-described embodiment, the present invention is applied to a mobile phone with a camera function. However, the present invention includes a digital camera and other shooting functions. The present invention can be applied to any portable electronic device as long as it has a communication function with a wireless base station. Further, in the above embodiment, the shooting prohibited areas A and B are provided separately for convenience of explanation, but some or all of them may be overlapped. Further, the portable electronic device used in the system of the present invention may not have the infrared communication function with the photographing prohibited infrared device 40. In this case, when the portable electronic device is a mobile phone with a camera function, It can be configured by software with almost no change to the existing hardware structure.
