Description

Device for Protection of illegally Taking a Photograph}

The present invention relates to a photographing prevention device for preventing illegal photographing, and to a device for distorting a photographed image or obstructing the operation of a camera so as to prevent illegal photographing of an image or video.

With the miniaturization of cameras and the development of wireless communication technology, it frequently occurs that cameras are used to photograph the body of another person or to secretly photograph facilities or data corresponding to business secrets.

Legal regulations and penalties for illegal filming are becoming stricter, but these regulations and punishments are not a fundamental solution, and even though regulations and punishments are becoming strict, the so-called'sneaky camera' is on the rise.

As a technique for preventing such a secret camera, a technique that detects a light beam for focus detection or a radio wave that a secret camera transmits data when photographing by a secret camera is used or is being developed. .

However, a device to which such a detection technology is applied is expensive, and it is very difficult for an individual to carry out a camera detection task secretly from time to time, especially in possession of such a device.

In particular, there is a problem that detection itself is impossible in the case of a camera that does not emit light rays for focusing, or when data is transmitted by wire or an image is stored in a memory built into the camera.

As a technology for preventing a camera from being secretly developed, a technology has been developed and used in part to distort the image acquired by the camera or prevent the camera from focusing.

As one such technology, Korean Patent Laid-Open Publication No. 10-2018-0057505 (Document 1) discloses an invention entitled'Secret Camera Prevention Device'.

The device of the invention of Document 1 includes a first light-emitting unit that emits infrared rays and a second light-emitting unit that emits one of red, green, and blue light, and secretly distorts the image of the camera by the light from these light-emitting units. It is composition and function.

As one such technology, in Korean Patent No. 10-1977017 (Document 2), the name'Illegal Photography Prevention Device' discloses the invention.

The device of the invention of Document 2 includes an infrared light emitting element and a light diffusion member for diffusing light emitted by the infrared light emitting element, and as a specific example of the light diffusion member, a lens having negative refractive power is disposed for each infrared light emitting element. Holding something.

The devices according to the invention of Documents 1 and 2 irradiate light in an infrared or visible region in a specific direction so as to distort an image photographed by a camera. However, due to the nature of a secret camera, a person who wants to prevent shooting by a secret camera cannot know the installation location or location of the camera, so irradiating infrared or visible light for image distortion only in a specific direction is performed by the camera secretly. There is a problem that photographing is prevented or that the photographed image cannot be distorted.

Korean Patent Application Publication No. 10-2018-0057505 (Document 1) Korean Patent No. 10-1977017 (Document 2)

The present invention is to provide a photographing prevention device that prevents unintended photographing by a camera or illegal photographing.

Specifically, it is intended to provide a photographing prevention device capable of preventing unwanted photographing or photographing of an object that becomes a trade secret by a person as a subject.

In particular, the present invention provides a photographing prevention device capable of substantially preventing illegal photographing by causing distortion of the photographed image with respect to a camera that can be placed in a wide area without knowing the location of the camera for illegal photographing. I'm trying to do it.

In many conventional techniques, infrared light or visible light belonging to near-infrared rays is used as a means of hindering image acquisition by a camera in preventing illegal photographing.

The inventors of the present invention are a result of irradiating various light belonging to the ultraviolet region from the infrared region toward the photographing region and the camera of the camera, and the visible ray in the infrared or near-infrared region has a large effect of obstruction of photographing due to the refraction of light, but is currently developed. In the case of commercially available light sources, especially LED light sources, the output of visible light in the infrared or near-infrared area has a weak output, so there is a certain degree of interference with shooting in the close area, but the shooting interference effect is significantly lowered in a location away from the light sources. Found.

In addition, the light belonging to the ultraviolet region has a strong output and a large photographic disturbance effect even at a long distance, but is not suitable for use as a light source of a photographing prevention device in that it has a great adverse effect on human vision or skin.

Based on these findings and considerations, in this invention, it was concluded that light belonging to the near-ultraviolet region is suitable as a light source of the photographing prevention device.

In addition, as a result of numerous experiments and measurements, it has been found that light sources with center wavelengths of 405 ㎚ and 460 ㎚, respectively, have high light output of commercially available light sources and excellent light spreading of light emitted from the light source, which is advantageous for light diffusion.

However, these light sources have a problem that it is difficult to emit light over a wide area because the scanning angle of the light source is narrow and the rotation or refraction angle is small.

Accordingly, as a solution to this problem, a concave lens for diffusing light from the light source is arranged in a hemispherical shape with the light source as the center so that the light is diffused over a wide range.

The photographing prevention device of this invention configured in this way,

A light emitting unit including a plurality of one or more of a light source having a center wavelength of 405 nm and a light source having a center wavelength of 460 nm,

A plurality of concave lenses arranged in a hemispherical shape centered on the light emitting part.

A power supply for supplying power to the light emitting unit, and

A switch that controls the supply of power from the power supply to the light emitting unit

Consists of including.

According to this configuration, near-ultraviolet light having high light output and excellent light spreading is output from the light emitting portion, and the output light is emitted in a wide range by a concave lens surrounding the light emitting portion in a hemispherical shape.

Since the near-ultraviolet light emitted from at least the concave lenses is emitted in a range of 180 degrees in front of the direction in which the light sources of the photographing prevention device of the present invention are arranged and the light is emitted, it is arranged at least in front of the photographing prevention device of the present invention. It is possible to prevent all cameras from being taken.

Here, the term “prevention” does not mean that the camera's shooting itself is not performed, but that the camera's focus cannot be set or that the captured image is distorted and thus the image of the subject cannot be acquired.

As an additional feature of the present invention, a plurality of light sources constituting the light emitting part may be arranged in an annular shape around one point, and the center of the annular shape may be a center of a hemisphere in which the concave lenses are arranged. In addition, the light source may be disposed in the center of the annular shape formed by the light sources.

According to this configuration, light from the light sources can be irradiated relatively uniformly over the front surface of the photographing preventing device according to the present invention, so that photographing by the camera can be prevented over a wide range.

As a further feature of this invention, the light sources may be configured to emit light alternately or each light source to flash. In addition, the light sources may be mounted on a rotatable frame, and the frame may be configured to rotate around the center of the annular shape of the light sources to a motor driven by receiving power from a power supply unit.

According to these configurations, since the light sources alternately emit light, flash, or rotate, when the camera attempts to acquire the focus on the subject, it is disturbed by the light from the photographing prevention device of the present invention disposed near the subject and does not acquire the focus. I can't. Therefore, it is possible to fundamentally prevent photographing by the camera.

As another additional feature of the present invention, a concave mirror may be disposed at the rear and side surfaces of the direction in which light is irradiated from the light sources. This concave mirror has a parabolic profile, and the center of the profile may be disposed on a line passing through the annular center of the light sources.

According to this configuration, when light from a light source exits to the rear or to the side, such light is reflected by the concave mirror, and is mainly reflected towards the light source by the profile of the concave mirror.

Accordingly, the light exiting to the rear or side of the light source is also directed to the front surface of the light source and is diffused forward by the concave lens, so that the intensity of the light irradiated from the photographing preventing device of the present invention is increased.

FIG. 2 is a diagram illustrating a state in which the concave lens is removed from the state shown in FIG. 1.

Hereinafter, as specific details for carrying out the present invention, a configuration and operation of a photographing prevention apparatus according to an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a state in which a light source, a concave lens, and a concave mirror are combined in a photographing prevention apparatus according to an embodiment of the present invention, and FIG. 2 shows a state in which the concave lens is separated from the light source.

Referring to these drawings, as a light source, seven LED modules 11 and 12 that emit light having a central wavelength of 460 nm are provided to form the light source unit 10.

The six LED modules 11 are arranged side by side adjacent to each other to form an annular shape, and one LED module 12 is disposed between them, that is, in the middle of the six LED modules 11. The LED modules (11. 12) differ only in the arrangement position, and the same one was used.

In this embodiment, the center wavelength is 460 nm and thus the LED modules 11 and 12 emitting blue visible light are used, but the center wavelength does not necessarily have to be 460 nm, and it is sufficient to have a center wavelength approximately close to this wavelength. Do. Further, as the light source, an LED module having a central wavelength of 406 nm and emitting violet visible light can be used. In addition, the light source is not limited to the LED module, but the LED module is preferable in terms of high efficiency, low heat generation, and compact size.

Each of the first and second concave lenses 21 and 22 is provided with a circular lens portion 23 inside a hexagonal or pentagonal circumference, and the circular lens portion 23 acts to diffuse light, The periphery 24 of the lens portion 23 on which the lens is not formed is also transparent and is formed like the lens portion, so that light is emitted through the periphery 24. Although not shown in the drawing, the outer surface of the periphery 24 The irregularities are provided so that the light passing through the silver is irregularly refracted to facilitate the diffusion of the light.

Covers 25 and 26 are provided below the first and second concave lenses 21 and 22 to cover the side surfaces of the light source unit 10. The covers 25 and 26 are also formed of a transparent material to emit light from the side to the periphery, but irregularities are formed on the outer surface so that the sides of the internal LED modules 11 and 12 are not clearly visible while promoting light diffusion. Has been.

The concave lens module 20 is formed so that the center of the hemisphere coincides with the center of the light source unit 10. That is, among the LED modules constituting the light source unit 10, the center of the LED module 12 disposed at the center of the six LED modules around the periphery coincides with the center of the hemispherical shape of the concave lens module 20.

However, their centers do not necessarily coincide, and the concave lens module 20 does not have to be disposed in a hemispherical shape, and may be configured to be disposed so as to cover the direction in which light is emitted from the LED modules as a whole.

According to this configuration, light emitted from the light source unit 10 is emitted to the outside through any one of the concave lenses 21 and 22 in the front.

The emitted light is diffused by the concave lenses 21 and 22, and eventually, the light emitted from the concave lens module 20 is emitted from the entire surface of the light source unit 10 except for the side and rear sides.

On the other hand, a concave mirror 30 is disposed behind the light source unit 10, that is, to the rear in the direction in which light is emitted from the LED modules 11 and 12.

The concave mirror has a parabolic profile, so when the light emitted from the light source unit 10 is reflected from the surfaces of the concave lenses 21 and 22, the concave mirror functions to return it to the front. . The parabolic profile allows the center to pass through between the LED modules 11 and 12 of the light source unit 10 and emit forward.

On the other hand, the power line 13 for supplying power to the LED modules 11 and 12 is disposed through the concave mirror 30, but extends from the rear of the LED modules 11 and 12 to the side and a battery (not shown) ) Can be connected.

A battery (not shown) and a switch (not shown) are connected to the control module to supply power, and the switch is provided so that the user can operate it. When the switch is turned on, the control module operates to supply power from the battery to the LED modules 21 and 22 to cause the LED modules 21 and 22 to emit light.

The user possesses or wears the photographing prevention device of this embodiment, and in a situation in which illegal photographing is suspected, the light source unit 10 is directed in the direction suspected to be installed, and the switch is turned on so that near-ultraviolet rays from the light source unit 10 are turned on. Illegal shooting is prevented by making it appear.

On the other hand, although not provided in the photographing prevention apparatus of this embodiment, a motion recognition sensor may be provided in the photographing prevention apparatus.

The motion recognition sensor detects motion in front of the concave lens module, and sends a detection signal to the control module when motion is detected. Even when the switch is turned on, the control module operates the light source unit and emits light when a detection signal from the motion recognition sensor is input without emitting light.
