TECHNICAL FIELD OF THE INVENTION
The present invention relates to an unauthorized shooting prevention system, and more particularly to an unauthorized shooting prevention system for a mobile terminal with a shooting function such as a digital camera or a camera-equipped mobile phone.
[0002]
[Prior art]
2. Description of the Related Art In recent years, portable terminals such as digital cameras and camera-equipped mobile phones have been reduced in size, making them portable and convenient, while privacy infringement such as a thief has become a social problem. Therefore, as a technique for preventing such a small camera from voyeur, for example, a system that issues a warning sound from a camera when shooting with a camera and notifies a person within the range of the warning sound that the shooting is performed, Systems and the like have been developed to prevent voyeurism by using both a warning sound and a light.
[0003]
In addition, as a conventional technique of this type, for example, in Japanese Patent Application Laid-Open No. 10-031265, a warning sound is generated to indicate that an image is to be captured of an image capturing target or that the image capturing has been performed, thereby calling attention. The technology is disclosed.
[0004]
Further, in Japanese Patent Application Laid-Open No. 2001-313006, infrared light which is invisible to humans but is received and reacted to the camera is irradiated to the outside from the subject with a certain intensity or higher, so that the subject can be captured from the voyeur camera. Protecting technology is disclosed. Furthermore, by using a luminous object that emits infrared light as a light source and directing the light directly or through an optical fiber to the front of the subject, (for example, the head and chest), the irradiation point is centered with respect to imaging from the front in the irradiation direction. There is disclosed a technique that makes it impossible to photograph a range of a certain radius.
[0005]
[Problems to be solved by the invention]
However, these conventional systems have the following problems. The first problem is that since a camera that performs photography emits a warning sound, it is useless in a loud noise place such as a downtown area or inside a train, and it is unclear who took it in a crowd.
[0006]
The second problem is that, if a warning sound is continuously emitted during shooting, shooting a moving image including sound also causes the warning sound to be recorded together, making it difficult to shoot a subject such as a bird that can only be shot in a quiet state. That is.
[0007]
A third problem is that if a warning is issued only once at the start of photographing, a warning sound can be output at another place and then the subject can be approached and photographed, so that voyeur photography cannot be prevented.
[0008]
A fourth problem is that when a warning sound is issued at the end of shooting, the camera shooting can be stopped away from the subject, so that voyeur shooting cannot be prevented.
[0009]
Fifth problem is that when irradiating infrared light from the subject to the outside to protect the subject from being shot by the voyeur camera, it is necessary to direct the light in the direction of the voyeur camera, preventing voyeur if the direction of the camera is unknown. That is not possible.
[0010]
A sixth problem is that when irradiating in all directions around the subject, it is necessary to wear a tool for irradiating the whole body with light, which is troublesome in daily life.
[0011]
The present invention has been made in view of the above problems, and the present invention prevents voyeurism by a portable terminal with a photographing function such as a digital camera or a camera-equipped mobile phone even in a loud noise place such as a downtown area or a train or crowded. It is an object of the present invention to provide a system for preventing unauthorized photographing.
[0012]
Another object of the present invention is to prevent the recording of a voyeur-prevention warning sound during shooting when shooting a moving image including sound, thereby enabling shooting of a subject even when shooting can be performed only in a quiet state. It is to provide a system for preventing illegal photographing.
[0013]
It is another object of the present invention to provide an unauthorized photographing prevention system which prevents unauthorized photographing even when the direction of the camera is unknown and is excellent in portability.
[0014]
[Means for Solving the Problems]
An unauthorized photographing prevention system according to the present invention is an unauthorized photographing prevention system including a photographing side portable terminal having a photographing function and a subject side portable terminal, wherein the photographing side portable terminal indicates that a photographing is being performed at the time of photographing. The object-side mobile terminal has a shooting rejection unit that sends a shooting rejection signal that disables the shooting function of the shooting-side mobile terminal when receiving the shooting-in-progress signal. And

The camera mode switch 201 is a switch that is turned on first when the user shoots with a camera. When the camera mode switch 201 is turned on, a photographing signal is transmitted from the signal transmitter 202, and at the same time, the shutter 204 is enabled by the shutter control unit 203.
[0020]
When the camera mode switch 201 is turned on, the signal transmitter 202 transmits a photographing signal to the outside of the portable terminal. The shutter control unit 203 enables the shutter 204 when the camera mode switch 201 is turned on. Further, when the photographing rejection signal is received by the signal receiver 205, the shutter 204 is switched to an invalid state by the shutter control unit 203, and photographing becomes impossible.
[0021]
The shutter 204 can shoot by pressing down the shutter 204 while the valid signal from the shutter control unit 203 is ON. The signal receiver 205 notifies the shutter control unit 203 when detecting a shooting rejection signal from the surroundings. As a result, the shutter 204 is switched to an invalid state, and photographing becomes impossible.
[0022]
The image storage control unit 206 transmits the image information obtained from the lens 207 to the storage device 208 by pressing the shutter 204. A lens 207 is a camera lens and transmits image information of a subject to the image storage control unit 206. The storage device 208 receives the image information transmitted from the lens 207 when the shutter 204 is pressed down from the image storage control unit 206 and stores the image information. The monitor 209 displays image information from the lens 207. Also, the image information stored in the storage device 208 is displayed.

[0024]
The setting change unit 301 is a unit for setting in advance the operation (described in FIG. 1) of the general portable terminal when detecting a signal during shooting. The setting storage unit 302 stores the setting value input by the setting change unit 301, and instructs an operation according to the setting when the signal receiver 303 detects a signal during shooting. For example, it instructs the signal transmitter 304 and the signal reception report unit 305 to perform operations such as transmission of an image rejection signal for image rejection and sound / light / vibration / display for image notification.
[0025]
The signal receiver 303 notifies the setting storage unit 302 when receiving the in-photographing signal from a nearby portable terminal. The signal transmitter 304 transmits a photographing rejection signal when there is a photographing rejection signal transmission request for photographing rejection from the setting storage unit 302. The signal reception report unit 305 performs an operation corresponding to a case where an operation request such as sound / light / vibration / display for photographing notification is issued from the setting storage unit 302.
