Description

  The present invention relates to a method for suppressing unauthorized photographing by a device having a photographing function such as a camera-equipped mobile phone or a digital camera.

  In recent years, with the spread of camera-equipped mobile phones and digital cameras, the damage of voyeurism and digital copying has also increased. When shooting with a shooting device, an unfair shooting is prevented by sounding a shutter sound, but it is difficult to identify a photographer in a noisy place.

  In addition, as a method of suppressing the communication function of the mobile phone, the radio device can output radio waves of the same frequency as the radio waves used when periodically searching for base stations (antennas) from the mobile phone, thereby enabling communication by interference. Although the function can be suppressed, the current photographing function is not affected by the transmission / reception of radio waves, and cannot be prevented by the above method.

  As a system that suppresses a photographing function, a system that detects a voyeurism of an individual by providing a device that detects that a photographing object has been photographed is known from Japanese Patent Laid-Open No. 2003-163822.

JP 2003-163822 A

  However, in the above-described method, it is necessary to provide a device for detecting that the image is taken for each object to be photographed. .

  That is, there is a problem that is not suitable when it is desired to suppress shooting within a certain area.

  Accordingly, an object of the present invention is to provide a method for inhibiting a photographing function by means for inhibiting photographing within a certain area.

  In order to achieve the above object, the present invention provides means for transmitting a signal for suppressing photographing within a specific area. In addition, in a camera-equipped mobile phone or digital camera that holds a shooting function, a function that can receive a signal for suppressing the above shooting, a function that can suppress shooting due to the reception, and a shooting device that is prevented from shooting A function to display is provided.

  When a user who has a camera device such as a camera-equipped mobile phone or digital camera that holds the shooting function in a specific area enters, the transmitter sends a signal to the camera device to prevent shooting at regular intervals. When the camera is turned on, the camera device receives a signal and controls the reception so that the shutter button cannot be pressed. Display on the display of the camera.

  When the user who owns the photographic device leaves the specific area, the photographic device is released from the specific area when it is detected that the signal output from the transmitter has not been received for a certain period of time. It is determined that it exists outside, and the deterrence function is automatically released.

  According to the present invention, since the photographing device can be automatically controlled and released depending on the transmission / reception state of the signal emitted by the transmitter, the function within the specific area is suppressed, thereby preventing unauthorized photographing. The reliability of the device itself in terms of security can be improved.

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

  FIG. 1 shows a block diagram of an embodiment to which the present invention is applied.

  In FIG. 1, reference numeral 10 denotes a photographing device that holds a photographing function such as a camera-equipped mobile phone or a digital camera, and 20 denotes a transmitter that can send a signal for inhibiting the function held by the photographing device.

  The photographing device 10 has a call function, a photographing function, and the like, a signal receiving unit 11 that receives a signal for inhibiting the function, a control unit 12 that inhibits and controls the function in the photographing device 10 by sending and receiving the signal, and a photographing device The display section 13 displays the suppression state of each function and the storage section 14 that holds the time when the function is not received and the signal output from the transmitter 20 is not received regularly. It is assumed that the data in the storage unit 14 does not disappear even when the power is turned off. Further, the transmitter 20 is installed in a specific area and has a function of transmitting different signals for inhibiting the function according to the function to be inhibited among the functions held by the photographing apparatus 10.

  Next, a method of inhibiting each function will be described with reference to the flowchart in FIG.

  Here, as an example, the function to be suppressed is limited to the shooting function.

  When the user who owns the photographing device 10 does not exist in the specific area where the function is inhibited, the function inhibition state of the storage unit 14 remains off (step 101). When the photographing device 10 enters a specific area where the function is inhibited, a signal for inhibiting the function is output from the transmitter 20 at a certain time interval to all the photographing devices existing in the specific area. There are various types of signals, such as infrared rays and wireless, but any type, frequency, etc. can be used as long as they can be received within the photographing apparatus.

  When the photographing apparatus 10 is powered on (step 102), the signal receiving unit 11 receives the signal output from the transmitter 20 unconditionally if it exists in the specific area (step 103), and the call function is performed in the specific area. When the function to be suppressed such as the shooting function or the shooting function is turned off (step 104), the control unit 12 performs control so that shooting is not possible even when the user presses the shooting button, and shooting of the shooting device is performed. The display unit 13 which is a part shows a suppression state such as “imaging off” to indicate that the corresponding function cannot be used (FIG. 4), and turns on the corresponding “suppression state” of the storage unit 14. (“Reception end time” is an initial value) (FIG. 3).

  When a signal is transmitted from the transmitter 20 at regular time intervals, when the photographic device 10 to be deterred enters a specific area, the specific function is not suppressed when the power is on, but also the admission The deterrence function is executed when a signal sent from the transmitter 20 is received even for a photographing device whose power is turned on later. Regarding deterrence when entering a specific area, it is expected that a signal for deterrence is generated from the entrance of an infrared gate or the like that has already been installed for the purpose of preventing theft. Once the function held by the photographing device 10 is inhibited, the photographing function is continuously inhibited while the signal output from the transmitter 20 is being received.

  When the shooting device 10 goes out of the specific area, when the signal output from the transmitter 20 is no longer received, when the “suppression state” is on and the “reception end time” is the initial value, The time when the reception is completed is stored in the “reception end time” of the storage unit 14.

  If a signal is not continuously received after a certain period of time has elapsed from the reception end time, it is determined that the photographing device 10 is outside the specific area, and the control unit 12 in the photographing device 10 At the same time, the display unit 13 displays the state where the suppression is released, turns off the “suppression state” of the storage unit 14, and returns the “reception end time” to the initial value.

  FIG. 3 shows data contents stored in the storage unit 14 in the photographing apparatus 10. The storage unit 14 is provided with a “suppression state” indicating whether or not each function held by the photographing device is suppressed and a “reception end time” indicating a time when the signal transmitted from the transmitter 20 is not received. We hold as standard of judgment to cancel automatically.

  FIG. 4 also shows the contents displayed on the display unit 13 in the photographing apparatus 10. A message (function name + suppression state (on, off)) indicating whether or not each function is inhibited is displayed on the screen so that the user who owns the imaging device can understand.

  Although the embodiment of the present invention has been described above, this mechanism is not limited to the shooting function, and can be applied to a case where another function held by the shooting device such as a call function is to be suppressed. Further, the transmitter 20 can be used as it is by expanding the function of a device that emits radio waves for suppressing the call function of a conventional mobile phone.
