Description

  The present invention relates to an image photographing restriction system for restricting an image photographing action by a wireless terminal having an image photographing function in an image photographing prohibited area.

  In recent years, in wireless terminals such as mobile phones and PHS (Personal Handyphone System), functions other than voice calls have been increased in value-added and functions, and in particular, the number of wireless terminals having an image shooting function has increased. It is remarkable. Wireless terminals with such an image shooting function have longer portability and ease of use compared to dedicated image shooting devices such as digital still cameras whose main function is image shooting. It has been widely accepted as a daily image-capturing application that doesn't care much. In addition, the image quality and other shooting functions are inferior to those of the dedicated image shooting terminal, but the difference is gradually getting smaller.

  In the case of a dedicated device for image capture, first of all, the appearance of the device itself informs the act of image capture to the surroundings, and it is also natural to take a posture to hold it through the viewfinder. Psychology that restrains unauthorized shooting in inappropriate places and situations works. On the other hand, in the case of a wireless terminal, unauthorized image shooting in a place and in a situation where it is difficult to shoot with a dedicated image shooting apparatus becomes conspicuous because of its simplicity. Examples of such places include bookstores, art museums, concert venues, and the like. Also, many recent mobile phones and the like have a data communication function with a network for transmitting and receiving e-mail and Internet information. In this case, an operation for sending and receiving e-mails and Internet information is performed while viewing the display screen. The similarity between this operation and the operation for capturing an image is one of the factors that promotes unauthorized image capturing. One can say.

  In addition, there is a possibility that the captured image data can be easily distributed via the network on the spot by the data communication function with the above-mentioned network, which also becomes a big problem for copyright protection.

  In order to solve the above problems, some commercially available wireless terminals having an image capturing function emit a sound effect when the shutter is released, and an LED (light emitting diode) indicating that the image capturing function is effective. Some measures are taken such as turning on the lamp. However, if it is a malicious user, actions such as closing a speaker that emits a sound effect or hiding an LED are easy and are not a fundamental solution.

  For example, there are Patent Documents 1 to 3 and the like as prior art relating to the use restriction of a wireless terminal having an image capturing function. Further, although not related to image capturing, there are, for example, Patent Documents 4 and 5 as prior arts related to the restriction of functions in a wireless terminal.

  Patent Document 1 identifies a user who receives a service, whether or not the user is in a state where the service can be used, and whether or not the service security is infringed by a person other than the user. If the user is identified according to the detection result, the service starts to be provided. If a situation in which the service is not available is detected while the service is being provided, or security is violated. A security device is disclosed that interrupts the provision of services when a situation is detected.

  In Patent Document 2, a charging center registers a charge for photographing by an information terminal in a predetermined facility when entering the predetermined facility, and distributes an object as charging information to the information terminal from a cell station in the predetermined facility. Detecting information terminals in a given facility by sending a wireless exploration request, permitting photographing for information terminals that have been registered for charging, and permitting photographing for information terminals that are not registered for charging A system is disclosed.

  In Patent Literature 3, when it is desired to prohibit shooting of a shooting-prohibited object, a shooting-prohibiting signal transmitting device transmits a shooting-prohibiting signal to the periphery thereof, and in a device such as a wireless terminal device having a shooting function, A video acquisition restriction system is disclosed in which the camera unit monitors the arrival of a shooting prohibition signal, and when the shooting prohibition signal has arrived, the camera unit stops outputting video data.

  In Patent Document 4, when a mobile phone output restriction management device sends an output restriction instruction signal to a mobile phone in a place where use of the mobile phone is restricted, and the mobile phone receives the output restriction instruction signal, Enter power limit mode, stop direct communication with the radio base station, and the mobile phone output limit management device will instead answer the call from the radio base station until the mobile phone in power limit mode goes out of place. A mobile phone output restriction system for responding is disclosed.

  In Patent Document 5, when a mobile phone enters a communication restricted area, a request for location registration is made, and this is received by a terminal use restriction device, and an alarm sound is output from a speaker. A wireless terminal use restriction system is disclosed.

  However, in Patent Documents 1 to 4, a control signal for prohibiting a function is transmitted to a wireless terminal, and the wireless terminal that has received the control signal is realized by means of stopping the function. There is a possibility of unintentionally controlling other areas. On the other hand, if the transmission radio wave is weakened, a non-delivery area may occur.

  Note that Patent Document 3 proposes transmission of a prohibition signal using an invisible light beam regardless of wireless radio waves, and if this is the case, leakage of the prohibition signal to the outside is eliminated by partitioning the facility. This can be said to be an effective way to place a beam transmitting device on the stage etc. and send it to the audience if it is a place where shooting is limited, such as a concert venue, but like a bookstore or a museum It is not suitable for places where shooting objects are difficult to limit.

  In Patent Document 5, the presence of a mobile phone is detected near the entrance of the prohibited area, but use within the area cannot be restricted. Further, since this is not a proposal for restricting image shooting but a restriction for voice communication, a process of requesting location registration can be used. However, such a measure cannot be taken if the prohibition of image shooting is an object.

JP 9-297735 A JP 2003-78810 A JP 2000-152217 A JP 2000-324539 A JP 2003-163967 A

  An object of the present invention is to solve the problems based on the above-described conventional technology, and without adversely affecting a wireless terminal outside the image shooting prohibited area, regardless of location or situation, and within the image shooting prohibited area. Another object of the present invention is to provide an image capturing restriction system that can restrict image capturing by a wireless terminal.

  In order to achieve the above object, the present invention relates to a wireless terminal having a function of wirelessly transmitting operation mode information of an image capturing function, and operation mode information disposed in an image capturing prohibition area and transmitted from the wireless terminal. A wireless receiving unit that receives and determines whether the image capturing function of the wireless terminal is valid or invalid based on the operation mode information, and the wireless terminal image capturing function is enabled in the wireless receiving unit. An image photographing restriction system is provided, comprising: an alarm unit that issues an alarm when it is determined that

  Here, the operation mode information is included in a radio signal transmitted from the radio terminal to the base station, and the radio receiving means transmits a radio signal transmitted from the radio terminal to the base station. It is preferable to receive the operation mode information.

  Further, every time the wireless terminal transmits the operation mode information, the transmission power level is gradually increased from the minimum output level to the maximum output level. When the transmission power level reaches the maximum output level, the wireless terminal again The transmission power level of the operation mode information is simultaneously transmitted when the operation mode information is repeatedly transmitted every predetermined time while controlling to gradually increase from the minimum output level to the maximum output level. Information is preferably transmitted.

  Further, it is preferable that a plurality of the wireless receiving means are arranged in the image photographing prohibited area, and the position of the wireless terminal where the image photographing function is effective is determined by the plurality of wireless receiving means arranged.

  Moreover, it is preferable that the alarm means includes a speaker, and as the alarm, a sound or an alarm sound is emitted to the owner of the wireless terminal.

  Preferably, the alarm means includes an alarm lamp, and the alarm is issued to the owner of the wireless terminal by lighting or flashing the alarm lamp.

  Further, it is preferable that the alarm means includes a bulletin board type monitor device and issues a message by text to the owner of the wireless terminal as the alarm.

  Moreover, it is preferable that the warning means issues the warning to a person in charge of monitoring in the image photographing prohibited area.

  In the image capturing restriction system of the present invention, the receiving device receives the operation mode information transmitted from the wireless terminal in the image capturing prohibition area, thereby determining the wireless terminal in which the image capturing function is effective, and the corresponding wireless Image capturing by the terminal can be suppressed. In the image capturing restriction system of the present invention, since the wireless receiving means determines whether the image capturing function is valid or invalid based on the operation mode information transmitted from the wireless terminal, the operation mode information transmitted from the wireless terminal is outside the image capturing prohibition area. Even if it leaks, there will be no problem. For this reason, the image capturing restriction system of the present invention is not limited in application place, and can be used in any place and situation.

  Hereinafter, an image capturing restriction system of the present invention will be described in detail based on a preferred embodiment shown in the accompanying drawings.

  FIG. 1 is a schematic configuration diagram of an embodiment of an image capturing restriction system of the present invention. An image capturing restriction system 10 shown in FIG. 1 is for restricting image capturing by a wireless terminal in an image capturing prohibition area. The wireless terminal 12, wireless receiving means 14, and alarm means 16 to be restricted. And.

  The wireless terminal 12 has a wireless communication function and further has an image photographing function, such as a mobile phone and a PHS. The wireless terminal 12 wirelessly transmits operation mode information M indicating whether the image shooting function is valid or invalid.

  Here, since the wireless terminal 12 is owned by the owner and enters the image photographing prohibited area 18, the wireless terminal 12 may not exist in the image prohibited area 18. Wireless terminal 12 may exist.

  The operation mode information M may be transmitted to the radio reception means 14 as a dedicated radio signal, but from the radio terminal 12 to the base station during regular radio communication such as regular communication with a base station, telephone call, or e-mail. It is preferable to transmit the radio signal included in the radio signal transmitted thereto. Thereby, the transmission means of the operation mode information M can be realized without providing any special means. In this case, the radio receiving means 14 described later acquires the operation mode information M by receiving a radio signal transmitted from the radio terminal 12 to the base station.

  Further, the operation mode information M may be transmitted at regular intervals, or irregularly, for example, when the image shooting mode is enabled. For example, when the operation mode information M is transmitted at regular intervals, each time the operation mode information M is transmitted, the transmission power level is gradually increased from the minimum output level to the maximum output level. When the maximum output level is reached, it is preferable that the transmission power level information is transmitted at the same time when the operation mode information M is transmitted repeatedly while controlling to repeatedly increase from the minimum output level to the maximum output level. .

  Thus, for example, when the wireless reception unit 14 can receive the operation mode information M from the wireless terminal 12 even when the transmission power level is low, the wireless terminal 12 is relatively close to the wireless reception unit 14 and is transmitted. If the power level is not large, if the operation mode information M from the wireless terminal 12 cannot be received, it can be determined that the wireless terminal 12 is located relatively far from the wireless receiving means 14, and the wireless receiving means 14 The approximate position of the terminal 12 can be grasped.

  Here, it is sufficient that at least one wireless reception unit 14 is disposed in the image capturing prohibition area 18, but a plurality of wireless reception units 14 are disposed as necessary when the image capturing prohibition area 18 is wide. Is preferred. Thereby, as described above, the operation mode information M is repeatedly transmitted from the wireless terminal 12 at regular intervals, and the transmission power level information is transmitted at the same time, thereby improving the position determination accuracy of the wireless terminal 12. it can. In this case, the wireless reception unit 14 can further improve the position determination accuracy by including an antenna with high directivity.

  Subsequently, the wireless reception unit 14 is arranged in the image capturing prohibition area 18 and receives the operation mode information M transmitted from the wireless terminal 12. Based on the operation mode information M, the image capturing function of the wireless terminal 12 is received. Determine whether is valid or invalid.

  Subsequently, the warning unit 16 issues a warning when the wireless reception unit 14 determines that the image capturing function of the wireless terminal 12 is effective.

  Examples of the alarm by the alarm means 16 include output of an alarm sound or warning message by a speaker, lighting or blinking of a warning lamp such as an LED, or message display using characters using a bulletin board type monitor device. The alarm may be issued using alarm means other than those exemplified here. Also, a plurality of alarm means may be provided and used in combination.

  The warning by the warning means 16 may be issued over the entire image photographing prohibition area 18 or directly to the owner of the wireless terminal 12 for which the image photographing function is effective. Alternatively, when the person in charge of monitoring is monitoring with a monitor or the like installed in the central management center, the detection person is notified by displaying detection information such as the position of the target wireless terminal 12 on the monitor monitor. It is also possible to use such that the manager in charge verbally prompts the owner of the target wireless terminal 12 to refrain from taking an image.

  In the image capturing restriction system 10, the operation mode signal M is wirelessly transmitted from the wireless terminal 12. When the person carrying the wireless terminal 12 enters the image photographing prohibited area 18, the operation mode information M wirelessly transmitted from the wireless terminal 12 is received by the wireless receiving means 14 installed in the image photographing prohibited area 18. When the operation mode information M indicates that the image capturing function is effective, the warning means 16 issues a warning to the user of the wireless terminal 12, for example.

  Thereby, it is possible to suppress image capturing by the wireless terminal 12 in the image capturing prohibition area 18. In the image capturing restriction system of the present invention, since the wireless receiving unit 14 determines the validity / invalidity of the image capturing function based on the operation mode information M transmitted from the wireless terminal 12, the operation mode information M transmitted from the wireless terminal 12 is Even if it leaks outside the image capturing prohibition area 18, no problem occurs. For this reason, the image capturing restriction system of the present invention is not limited in application place, and can be used in any place and situation.

The present invention is basically as described above.
The image capturing restriction system of the present invention has been described in detail above. However, the present invention is not limited to the above-described embodiment, and various modifications and changes may be made without departing from the spirit of the present invention. It is.
