It is a schematic diagram which shows the structure of the outline of the communication system which is embodiment of this invention. It is a block diagram which shows the schematic structure of the communication apparatus in embodiment of this invention. 1 is a schematic block configuration diagram of a center device in an embodiment of the present invention. It is a general | schematic flowchart which shows the setting process of the camera control mode performed by a communication apparatus.

  FIG. 1 is a schematic diagram showing a schematic configuration of a communication system according to an embodiment of the present invention. The system includes communication devices 2 and 4, a center device 6 and a communication network 8. The communication device 2 is a communication device having the characteristics of the present invention relating to prevention of unauthorized use of the camera function. In this embodiment, the owner is a security guard 10 of a security company. The communication device 2 normally has a limited camera function to prevent unauthorized photographing. The limitation of the camera function can be achieved by prohibiting the operation of the camera function itself or prohibiting the recording of images taken using the camera function. As a result, the security guard 10 cannot illegally acquire an image using the camera function of the communication device 2.

However, for example, in a situation where various disasters such as a large earthquake have occurred, the security company needs to grasp the situation of the affected area where the guards 10 are present. For this reason, when the communication device 2 receives the disaster information from the disaster information distribution device 9 connected to the communication network 8, it temporarily cancels the camera function shooting restriction, and the security guard 10 shoots the situation of the disaster area, Allow this to be recorded and transmitted.
Note that the communication device 4 is an example of a communication partner of the communication device 2, and is not necessarily a communication device having the characteristics of the present invention.

  The communication devices 2 and 4 have a mobile communication function. For example, the communication devices 2 and 4 are a smartphone, a tablet computer, and a mobile phone. The communication devices 2 and 4 are wirelessly connected to the mobile communication base station 16 in the vicinity thereof, and can communicate with other communication terminals and the like via the mobile communication base station 16 and the communication network 8.

  The disaster information distribution device 9 is a device managed by a disaster information distribution provider (a provider that provides a disaster information distribution service such as a mobile phone carrier). In the following embodiment, an example in which a distribution provider distributes an earthquake early warning as disaster information will be described, but the scope of the present invention is not limited to this. As the disaster information of the present invention, for example, information on various disasters such as information on tsunami prediction, warnings on typhoons and tornadoes, information on fire, information on evacuation recommendations, and the like can be applied.

  When the disaster information distribution device 9 receives information such as the earthquake epicenter and magnitude (magnitude) analyzed by an organization such as the Japan Meteorological Agency when an earthquake occurs, the disaster information distribution device 9 is predicted to be affected by the earthquake (for example, seismic intensity 3 or more). The mobile communication base station 16 in the area) has a function for distributing this earthquake information as an emergency earthquake bulletin. Thereby, the earthquake early warning is delivered to the communication devices 2 and 4 existing in the communication area of the mobile communication base station 16 to be distributed.

  In this example, the case where an earthquake early warning is distributed only to the influence of an earthquake and the local communication devices 2 and 4 will be described, but the scope of the present invention is not limited to this. For example, the disaster information distribution device 9 distributes the earthquake early warning to all the communication devices 2 and 4, and determines whether or not the communication device 2 or 4 is an area affected by the earthquake from its own location information. You may judge. Since such a method for distributing disaster information such as an earthquake early warning is already widely known, detailed description thereof is omitted here.

  Next, the communication device 2 having the communication restriction function of the present invention will be described in detail. FIG. 2 is a block diagram illustrating a schematic configuration of the communication device 2. In addition to the control unit 20 and the storage unit 22, the communication device 2 includes a wireless unit 24, an operation unit 26, a camera 28, a microphone 30, a speaker 32, a display unit 34, and a vibration motor 36.

  The radio unit 24 includes a base station communication unit and a GPS receiving unit. The base station communication unit is a mobile communication unit that performs wireless communication with the mobile communication base station 16. The communication device 2 is monitored by the base station communication unit via the mobile communication base station 16 and the communication network 8. Communication with the center device 6 of the center 14, the other communication device 4, and the disaster information distribution device 9 is possible. The GPS receiver receives a GPS signal from a GPS satellite and acquires GPS information corresponding to its current position.

  The operation unit 26 is an input means for the security guard 10 to select an operation of the communication device 2 and to give an instruction to the control unit 20, and includes, for example, various button switches and a touch panel.

The camera 28 is an imaging unit that captures an image of a subject such as a person or a landscape in accordance with the operation of the operation unit 26.
The microphone 30 is a sound collection unit that collects the voice of the guard 10 during voice communication or the like.
The speaker 32 outputs the voice of the other party (the third party who owns the communication device 4) during voice communication, or outputs a ringing tone when an incoming call is received or an e-mail is received. An audio output unit.
The display unit 34 is an image display unit such as a liquid crystal display.
The vibration motor 36 provides a vibrator function for vibrating the communication device 2.

  The wireless unit 24, the operation unit 26, the camera 28, the microphone 30, the speaker 32, the display unit 34, and the vibration motor 36 are connected to the control unit 20 and operate upon receiving a signal from the control unit 20, or send signals to the control unit 20. Is output.

The storage unit 22 is a ROM (Read Only
Memory), RAM (Random Access)
Various programs executed by the control unit 20 and necessary data are stored. In particular, the disaster reference information 50 and the center device address information 52 are registered in the storage unit 22 in advance. The disaster standard information 50 is information that defines a target disaster (hereinafter referred to as a specific disaster) for which the transmission restriction in the communication device 2 is released, and the disaster indicated in the disaster information distributed by the disaster determination means 42 is a specific disaster. Use if there is. When the emergency earthquake bulletin is targeted, for example, a seismic intensity of 4 or more is set as the base seismic intensity to be canceled. The center device address information 52 is a telephone number or an IP address of the center device 6 and is used for communication with the center device 6. In addition, the storage unit 22 is provided with an area for storing image data 54 photographed by the camera 28 and instructed to be saved.

  The control unit 20 is configured using a microprocessor or the like, and performs various processes according to a program to be executed. For example, the control unit 20 functions as a communication control unit 40, a camera control unit 41, a disaster determination unit 42, a mode setting unit 44, and an image protection unit 46.

  The communication control means 40 constitutes a communication unit that performs a voice communication function and an Internet connection function together with the wireless unit 24. Specifically, in voice communication, a line connection is established with a communication terminal (communication device) as a communication partner, and a voice signal converted into an electric signal by the microphone 30 is transmitted via the communication control means 40 to the wireless unit. 24, and the voice signal converted into the radio signal by the radio unit 24 is transmitted to the mobile communication base station 16. The radio signal received from the mobile communication base station 16 is detected by the radio unit 24, and the communication control means 40 inputs the extracted audio signal and outputs it from the speaker 32 via the audio output circuit.

  The camera control unit 41 constitutes an imaging unit together with the camera 28 and controls the operation of the camera 28. For example, when the user operates the operation unit 26 to activate the camera function, the camera control unit 41 drives the solid-state imaging device constituting the camera 28 to capture an image, captures an image signal from the camera 28, and displays the image on the display unit 34. Display the input image. When a shutter operation is performed, the camera control unit 41 captures and buffers the input image and displays the captured image on the display unit 34. When a storage operation is performed, the camera control unit 41 displays the captured image as image data 54 in the storage unit 22. Write and record in the area.

  Further, the camera control means 41 restricts the photographing function using the camera 28 in accordance with the camera control mode set by the mode setting means 44. When the camera function activation operation is performed via the operation unit 26 and the restriction mode is set, the camera control unit 41 ignores the activation operation and does not activate the camera 28. On the other hand, when the release mode is set, the shooting / recording process is executed according to the input operation without limiting the shooting function. As a method of restricting the camera function, instead of disabling the camera function start operation and prohibiting the camera 28 from starting, the camera function application program itself is prohibited from starting and the shutter operation is disabled to capture. A configuration may be adopted in which recording of a captured image in the storage unit 22 is prohibited by prohibiting or invalidating a save operation.

  When the disaster determination unit 42 receives the disaster information distributed from the disaster information distribution device 9 via the wireless unit 24, the disaster determination unit 42 refers to the disaster reference information 50 in the storage unit 22 and the received disaster information corresponds to the specific disaster. It is determined whether or not. Specifically, if the earthquake seismic intensity of 4 or more is set in the disaster standard information 50, it is determined that the received emergency earthquake bulletin indicates, for example, a seismic intensity of less than 5, a specific disaster, and a seismic intensity of 3 is specified. Judge that it is not a disaster.

The mode setting means 44 sets a mode for refusal of photographing by the user. There are two types of camera control modes to be set. One is a restriction mode in which photographing is prohibited as a mode for restricting the camera function, and the other is a release mode in which photographing restriction is released and photography is permitted. The mode setting means 44 normally sets the communication apparatus 2 to the restriction mode, and when receiving disaster information indicating a specific disaster, temporarily switches to the release mode.
When the mode setting unit 44 receives disaster information indicating a specific disaster and switches to the release mode, the mode setting unit 44 refers to the center device address information 52 of the storage unit 22 and transmits the disaster reception information to the center device 6. The disaster reception information includes the contents of the received disaster information.

  The mode setting means 44 counts the elapsed time since the camera control mode is switched from the restriction mode to the release mode, and automatically switches from the release mode to the restriction mode again when a preset release time has elapsed. Further, when the mode return signal is received from the center device 6 before the release time elapses, the camera control mode is switched to the limit mode. Furthermore, when the corrected disaster information is distributed from the disaster information distribution apparatus 9 to the distributed disaster information, and this corrected disaster information does not indicate a specific disaster, the camera control mode is switched to the restriction mode.

  The image protection means 46 prohibits the user from operating the communication device 2 to erase the image data 54 photographed by the camera 28 from the storage unit 22 or copying or moving it to another recording medium. . In addition, the image protection unit 46 prohibits the attachment of image data to a transmission mail to a destination other than a preset transmission destination such as the center device 6. Note that the image data protection function by the image protection means 46 is not released even when the camera restriction mode is set to the release mode.

  Next, the center device 6 will be described in detail. The center device 6 is installed in a monitoring center 14 operated by a security company or the like to monitor a monitoring area. In addition, the center device 6 manages the security guard 10 such as a security headquarters that dispatches security guards 10, a command headquarters for issuing instructions to the security guards 10 remotely, and a disaster prevention headquarters provided in a disaster prevention center in a large building. It may be installed in the facility to perform.

FIG. 3 is a schematic block diagram of the center device 6. The center device 6 includes a communication unit 60, a display unit 62, an operation unit 64, a storage unit 66, and a control unit 68.
The communication unit 60 is connected to the communication network 8 and communicates with the communication device 2 carried by the security guard 10.
The display unit 62 includes a display device such as a liquid crystal display, a buzzer, an LED, and the like.
The operation unit 64 includes an input device such as a keyboard and a mouse.

  The storage unit 66 is realized by a memory device such as a ROM or a RAM, and stores various programs executed by the control unit 68 and necessary data. In particular, the storage unit 66 stores disaster report information 70. The disaster report information 70 includes address information (telephone number, IP address, or information on a security guard who is a user) of the communication apparatus 2 that transmitted the disaster reception information, disaster details (such as seismic intensity), and reception time of the disaster reception information. Are associated with each other.

  The control unit 68 is configured using a microprocessor or the like, and performs various processes according to the program to be executed. When receiving the disaster reception information transmitted from the communication device 2 via the communication unit 60, the control unit 68 associates the disaster content and the reception time read from the disaster reception information with the address information of the transmission source communication device 2, and the disaster report The information is stored in the storage unit 66 as information 70. The disaster report information for each communication device 2 that has transmitted the disaster reception information is automatically deleted when a preset release time has elapsed. As a configuration for receiving a signal indicating that the communication device 2 has returned to the restriction mode, the disaster report information related to the communication device 2 may be deleted when the signal is received.

  Further, the control unit 68 generates screen information that can be specified by at least the communication device 2 that transmitted the disaster reception information based on the disaster report information 70 and causes the display unit 62 to display the screen information. As a result, the monitoring staff of the monitoring center 14 can check which guard 10 is in the affected area and which communication device 2 is in a state where the photographing restriction is released. The monitor who has confirmed the disaster display screen distributes an instruction to report an image of the surroundings by e-mail to the communication device 2 in the affected area in order to grasp the situation of the affected area. The communication device 2 carried by other guards is contacted to perform other appropriate operations according to the situation, such as dispatching other guards to the guards 10 in the affected area. In addition, the control unit 68 transmits a mode return signal to the communication device 2 after receiving a report of the damage situation from the communication device 2 included in the disaster report information 70 or in response to an operation by a monitor.

Next, the flow of the camera control mode setting process in the communication apparatus 2 will be described with reference to FIG. FIG. 4 is a schematic flowchart illustrating a camera control mode setting process executed by the control unit 20 of the communication device 2.
As described above, the camera control mode of the communication device 2 is normally set to the restriction mode. When the disaster information distributed from the disaster information distribution device 9 is received, the following processing is executed.

When receiving the disaster information, the communication device 2 determines whether or not the disaster information indicates a specific disaster determined as a transmission restriction release target (S100). If no specific disaster is indicated, the restriction mode is maintained and the process is terminated.
When the disaster information indicating the specific disaster is received, the communication device 2 switches the camera control mode from the restriction mode to the release mode to release the photographing restriction (S102), and transmits the disaster reception information to the center device 6 (S104). .

  When the communication device 2 transmits the disaster reception information, the communication device 2 starts a timer for measuring a predetermined time and starts measuring the elapsed time after the release mode is set (S106). For example, the timer time (release time) is set to 120 minutes. Then, until the set release time elapses, the reception of the corrected disaster information transmitted from the disaster information distribution device 9 and the reception of the mode return signal transmitted from the center device 6 are waited (S108 to S112). .

When the corrected disaster information is received from the disaster information distribution device 9 before the cancellation time elapses and the content of the disaster information indicates that the disaster is not a specific disaster (Yes in S108), the camera control mode is returned from the cancellation mode to the restriction mode. (S114). When the mode return signal is received from the center device 6 until the release time elapses (Yes in S110), the camera control mode is returned to the restriction mode (S114).
If the release time elapses after switching to the release mode without receiving the corrected disaster information and the mode return signal (Yes in S112), the camera control mode is returned to the restriction mode (S114). The communication device 2 ends this processing when switching from the release mode to the restriction mode is set.

  As described above, the communication device 2 used in the communication system according to the present embodiment normally has a limited shooting function, and when specific disaster information is received, the limitation is released and shooting by the camera function is performed. It can be carried out. For this reason, it is possible to record and report images of disaster situations in the event of a disaster while suppressing the shooting of confidential information regardless of whether there is an unintentional private shooting or intention of fraud. .

The communication device and the communication system of the present invention are not limited to the above embodiment, and various modifications can be applied.
For example, the mode setting unit 44 may be configured to return to the prohibit mode at the timing when transmission of an e-mail with an image attached to the center device 6 is detected after setting to the release mode. In the configuration using the timer, the return to the restriction mode may be performed when the set release time elapses or when the e-mail transmission is completed.

Moreover, in the said embodiment, although it was set as the structure switched to cancellation | release mode when the received disaster information shows a specific disaster, it can also be set as the structure switched to cancellation | release mode irrespective of the content of disaster information. In this case, the determination process of S100 is omitted in the flowchart of FIG.
Further, the period for setting the release mode may be varied depending on the type of disaster information received from the disaster information distribution device 9 and the disaster level. For example, if the content of the earthquake early warning is seismic intensity 3, it is 10 minutes, seismic intensity 4 is 30 minutes, seismic intensity 5 is less than 60 minutes, and seismic intensity 5 or more is 12 hours. Also, 120 minutes for typhoon warning, 60 minutes for tornado warning, and 180 minutes for evacuation advisory. In this case, the communication device 2 stores the release time corresponding to the disaster content in the storage unit 50, and the disaster determination unit 42 determines to which specific disaster the received disaster information corresponds. And the mode setting means 44 measures the cancellation | release time according to the content of the determined specific disaster, and returns to restriction | limiting mode when the cancellation | release time passes after switching to cancellation | release mode.

In the above embodiment, correction of disaster information may not be considered in the termination condition of the release mode. In this case, the process of S108 is omitted in the flowchart of FIG.
Further, only one of reception of the mode return signal from the center device 6 and the elapse of the release time may be used. In the case of a configuration in which the mode return signal is not used and only the release time is used, the process of S110 is omitted in the flowchart of FIG. Omitted.

  Further, instead of the configuration in which the communication device 2 counts the release time, the center device 6 may be configured to count the release time. In this case, the center device 6 transmits a mode return signal to the communication device 2 when a predetermined release time has elapsed after receiving the disaster reception information from the communication device 2. When the connection with the communication device 2 is attempted and the connection fails, for example, the center device 6 repeatedly tries to transmit a mode return signal at a predetermined time interval. When receiving the mode return signal, the communication device 2 switches from the release mode to the restriction mode. In this configuration, the center device 6 can set the time limit for the release mode to a different length depending on, for example, the time zone of the day.

  Moreover, the communication apparatus 2 is good also as a structure which displays cancellation | release time on the display part 34, when switching setting from restriction | limiting mode to cancellation | release mode is carried out. Thereby, the security guard 10 can recognize the given photographing permission time, and can take care that the photographing of the disaster situation and the recording / transmission of the image are finished within the time.

  Furthermore, in the present embodiment, image data such as an image taken by the communication device 2 and image data such as the shooting time are recorded in the storage unit 22 and protected by the image protection unit 46 so as not to be tampered. 6 may be recorded. In this configuration, for example, when the recording of the photographed image in the storage unit 22 is completed, the image data related to the photographed image is transmitted to the center device 6, and the center device 6 records the image data in the storage unit 66. Note that at the timing when the communication device 2 returns from the release mode to the restriction mode, the communication device 2 transmits image data related to the image captured during the release mode to the center device 6 and the center device 6 associates the image data with the disaster report information. The image data can also be recorded. Accordingly, the monitoring center 14 can collectively record the images taken by the communication device 2 during the release mode in association with the disaster report information.

  Further, the communication device 2 is configured to generate sound from the speaker 32 continuously or intermittently during the period set in the permission mode, or to generate vibration by driving the vibration motor 36. You can also. By comprising in this way, the guard 10 can recognize that the restriction | limiting of the camera function is cancelled | released.

  In the above embodiment, the communication device 2 receives the disaster information from the disaster information distribution device 9. However, the present invention is not limited to this, and the center device 6 may receive the disaster information. In this case, the control unit 68 of the center device 6 determines whether the disaster information received via the communication unit 60 is specific disaster information. If the disaster information is specific disaster information, the disaster area indicated by the disaster information is determined. A mode switching signal is transmitted to all the communication devices 2 of the security guard 10 located in (area) so that the camera control mode is set to the release mode. For example, the center device 6 registers the jurisdiction area of the guard 10 in advance in association with the communication device 2 and determines the jurisdiction area corresponding to the disaster area indicated by the received disaster information. And a mode switching signal is transmitted with respect to the communication apparatus 2 linked | related with the extracted jurisdiction area. Alternatively, the center device 6 manages the location information of all the communication devices 2 using GPS or the like, determines the communication device 2 in which the current location is included in the disaster area indicated by the received disaster information and its adjacent area, and A mode switching signal may be transmitted to the communication device 2 that performs the above operation.

  In the embodiment described above, an example of restricting outgoing calls from the communication device 2 has been described. However, for emergency special numbers such as 110 (Police), 118 (Coast Guard), and 119 (Fire) As an exception, it may be possible to make an unconditional call.
