That is, the photographing prevention system of the present invention is configured such that when photographing a photographing object with the photographing apparatus, the interference light having the pattern shape is irradiated in the direction of the photographing apparatus. Thereby, even if a photographing object is photographed by the photographing apparatus, it is possible to prevent the photographing object from being photographed as it is. Therefore, it is possible to protect the copyrights of works exhibited at museums and exhibitions, and to prevent leakage of trade secrets by photographing products and know-how of factories and the like.

  In the imaging prevention system of the present invention, the light emitting unit can irradiate light having a wavelength outside the visible region. The light irradiated by the light emitting unit can be, for example, infrared (wavelength: 0.75 to 1000 μm). Since light of such a wavelength is safe, handling can be facilitated. In addition, it is possible to prevent the photographing object from being photographed as it is by a photographing apparatus including an image sensor such as a CCD or a CMOS.

  In this way, by setting the light emitted from the light emitting unit to have a wavelength outside the visible region, when a viewer views the object to be photographed with the eyes, the user observes and observes the object to be photographed as usual. be able to. On the other hand, when a viewer tries to photograph an object to be photographed with the photographing device, overexposure occurs in the portion irradiated with the interference light, and the corresponding portion in the photographed image data is whitened and photographed. It will be in the state where was given.

  The photographing prevention system of the present invention may further include a reflecting member that is disposed on the front side of the photographing object and reflects the light, and the light emitting unit irradiates the reflecting member with light having a pattern shape. be able to.

  Here, the reflecting member can be made of a material that transmits visible light. As a result, when the viewer views the object to be photographed with the eyes, the object to be photographed can be viewed and observed as usual.

  In the photographing prevention system of the present invention, the light emitting unit may include a light source and a mask that has a pattern shape and allows a part of the light emitted from the light source to pass therethrough.

  In the photographing prevention system of the present invention, a part of the reflective member may have a pattern shape in which a reflectance with respect to the light from the light emitting unit is different from other areas.

  The reflective member may be configured such that in a part of the region having a pattern shape (hereinafter referred to as a pattern shape formation region), the reflectance with respect to the light from the light emitting unit is higher than that of the other regions. In this case, the reflectance of the light from the light emitting portion may be lower than that in other regions. When attempting to photograph an object to be photographed with a photographing device, the intensity of the reflected light is high in the portion where the reflectance to the light from the light emitting portion is high, overexposure occurs, and the corresponding portion in the photographed image data is white. Is photographed and is given a pattern shape. Further, the reflecting member may be configured such that in the pattern shape forming region, the reflectance in a predetermined direction is higher or lower than other regions. Here, the predetermined direction can be a direction of a position where the photographing apparatus is assumed to be arranged.

  The imaging prevention system of the present invention further includes a reflecting member that is disposed on the front side of the object to be imaged, and that a part of the region has a pattern shape that is different in reflectance from the light emitting unit from the other regions. The light emitting unit can irradiate the reflective member with light.

  Here, the reflecting member can be made of a material that transmits visible light. As a result, when the viewer views the object to be photographed with the eyes, the object to be photographed can be viewed and observed as usual.

  In the photographing prevention system of the present invention, the reflecting member can be arranged so that light emitted from the light emitting unit is reflected in a direction of an observation position where the photographing apparatus is assumed to be arranged. . In the photographing prevention system of the present invention, the reflecting member can be disposed at an angle with respect to the photographing object, and the light emitting unit is configured to emit the light in a direction different from a position where the photographing object is disposed. Can be irradiated.

  Here, the direction different from the arrangement position of the object to be imaged is a direction in which the light irradiated from the light emitting unit is not incident on the object to be imaged when traveling straight. For example, the light emitted from the light emitting unit can be emitted in a direction substantially parallel to the surface of the object to be imaged. Moreover, it can adjust suitably according to the positional relationship with an imaging | photography object and the viewing position where a viewer is supposed to view an imaging | photography object. By setting it as such a structure, the light irradiated to a to-be-photographed object can be reduced, and the influence on a to-be-photographed object can be eliminated.

  In the photographing prevention system of the present invention, the light emitting unit is arranged on a back side of the photographing object, and can be configured to irradiate light from a back surface of the photographing object, and transmits the photographing object. Depending on the difference in the degree of light, it is possible to give a pattern shape to the photographing object in the image data obtained by photographing the photographing object with a photographing device.

  Here, the object to be photographed can transmit at least part of light, such as a poster or a painting. In such a case, the degree of transmission of the light emitted from the light emitting unit varies depending on the color distribution (such as shading) and the material of the object to be photographed. In places where the intensity of light passing through the object to be photographed is strong, overexposure occurs when the object to be photographed is photographed by the photographing apparatus, and the corresponding part in the image data is whitened. On the other hand, in a place where the intensity of light passing through the object to be photographed is weak, even if the object to be photographed is photographed by the photographing device, the state is almost taken as it is. Thus, according to the photographing prevention system of the present invention, a pattern shape can be imparted to the photographing object in the image data photographed by the photographing device, depending on the difference in the degree of light transmitted through the photographing object.

  In the photographing prevention system of the present invention, the light emitting unit can irradiate the photographing object with light having a pattern shape.

  By adopting such a configuration, in addition to the pattern shape generated due to the difference in the degree of light transmitted through the photographing object, another pattern shape is added to the photographing object in the image data of the photographing object photographed by the photographing device. Can be granted.

  According to another aspect of the present invention, there is provided a photographing prevention system comprising: a sensor that detects the presence of a person near the object to be photographed; and a control unit that starts irradiation of light by the light emitting unit when the sensor detects the presence of a person. Further can be included.

  By doing so, when there is no person near the object to be photographed, the light emission by the light emitting unit is turned off, and energy saving and the like can be achieved.

  According to the present invention, there is provided an imaging prevention method characterized in that a pattern shape is imparted to the imaging object in image data obtained by imaging the imaging object with an imaging device by light emitted from the light emitting unit. .

  It should be noted that any combination of the above-described constituent elements and a conversion of the expression of the present invention between a method, an apparatus, a system, a recording medium, a computer program, etc. are also effective as an aspect of the present invention.

  As described above, according to the present invention, it is possible to prevent an object to be photographed to prevent voyeurism or the like from being photographed as it is by a commonly used photographing apparatus.

In the following embodiments, similar constituent elements are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

(First embodiment)
FIG. 1 is a schematic side view illustrating the configuration of the photographing prevention system according to the present embodiment.
The photographing prevention system 150 is configured to give a pattern shape to the photographing target in the image data obtained by photographing the photographing target 200 with the digital camera 300 (photographing device) by the light emitted from the light emitting unit 100. Here, the digital camera 300 can be configured to include an image sensor such as a charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS). The photographing prevention system 150 according to the present embodiment is configured to prevent the photographing target 200 from being photographed as it is by the general digital camera 300 having such a configuration.

  The light emitting unit 100 is arranged on the back side of the shooting target 200 and is configured to irradiate light from the back of the shooting target 200. The light emitting unit 100 is arranged to emit light in the direction of a viewing position where a viewer is supposed to view the shooting target object 200 via the shooting target object 200. Here, the light source 101 of the light emitting unit 100 is formed over the entire back surface of the photographing object 200. In FIG. 1, the light emitting unit 100 and the imaging target object 200 are illustrated apart from each other in order to show light rays, but the light emitting unit 100 may be provided in contact with the imaging target object 200.

  The degree of transmission of the light emitted from the light source 101 of the light emitting unit 100 differs depending on the color distribution (such as shading) of the object 200 to be photographed. In places where the intensity of light transmitted through the subject 200 is strong, overexposure occurs when the subject 200 is photographed by the digital camera 300, and corresponding portions in the image data are whitened. On the other hand, in a place where the intensity of light transmitted through the photographing object 200 is weak, even if the photographing object 200 is photographed by the digital camera 300, the state is almost taken as it is. As described above, according to the photographing prevention system 150 according to the present embodiment, the pattern shape is given to the photographing target in the image data photographed by the photographing device according to the difference in the degree of light transmitted through the photographing target 200. Can do.

  The light source 101 of the light emitting unit 100 irradiates light having a wavelength outside the visible region. In this Embodiment, the light which the light source 101 of the light emission part 100 irradiates can be infrared rays (wavelength 0.75-1000 micrometers). The light source 101 can be, for example, a fluorescent lamp or a light emitting diode that emits infrared light.

  By irradiating such a light from the light emitting unit 100 and transmitting the photographing object 200, when the viewer views the photographing object 200 with the eyes, the light emitted from the light emitting unit 100 is visible. Therefore, the subject 200 can be viewed as usual. On the other hand, when the viewer tries to photograph the object 200 with the digital camera 300, overexposure occurs in a portion where the light transmittance is high, the corresponding portion in the photographed image is whitened and photographed, and the pattern shape is It will be in the granted state. In addition, when the viewer tries to photograph the object 200 while looking at the display of the digital camera 300, the image data that has passed through the image sensor of the digital camera 300 is displayed on the display. Further, it can be seen that a pattern shape is given to the photographing object 200 to be photographed. Therefore, it is possible to reduce the willingness of the viewer to photograph the object 200 to be photographed.

Here, the light-colored portion of the subject 200 is over-exposed by the digital camera 300 and becomes white because the transmittance of light emitted from the light emitting unit 100 is high. On the other hand, the dark color portion of the object 200 remains as it is because the transmittance of the light emitted from the light emitting unit 100 is low.

  As described above, according to the photographing prevention system 150 according to the present embodiment, when the photographing object 200 that is normally viewed when the viewer sees it with the digital camera 300 is photographed, the shading of the photographing object 200 is contrasted. Accordingly, a white portion is partially generated, and the image data of the photographing target 200 cannot be obtained as it is. Thereby, even if the photographing target 200 for which voyeurism or the like is desired is photographed, it is possible to prevent the photographer from obtaining the image data as it is. In addition, when the digital camera 300 has a display and the viewer takes a picture of the subject 200 while looking at the display, the image data 310 as shown in FIG. 2B is displayed on the display. It is possible to reduce the willingness of the viewer to photograph the object 200 to be photographed.

  The reflective member may be configured such that in a part of the region having a pattern shape (hereinafter referred to as a pattern shape formation region), the reflectance with respect to the light from the light emitting unit is higher than that of the other regions. In this case, the reflectance of the light from the light emitting portion may be lower than that in other regions. When attempting to photograph an object to be photographed with a photographing device, the intensity of the reflected light is high in the portion where the reflectance to the light from the light emitting portion is high, overexposure occurs, and the corresponding portion in the photographed image data is white. Is photographed and is given a pattern shape.

For example, the light emitted from the light emitting unit can be emitted in a direction substantially parallel to the surface of the object to be imaged. Moreover, it can adjust suitably according to the positional relationship with an imaging | photography object and the viewing position where a viewer is supposed to view an imaging | photography object. By setting it as such a structure, the light irradiated to a to-be-photographed object can be reduced, and the influence on a to-be-photographed object can be eliminated.

In the apparatus of the present invention, the light emitting unit is disposed on the back side of the object to be photographed, and can be configured to emit light from the back surface of the object to be photographed. Depending on the degree of difference, a pattern shape can be given to the photographing object in the image data obtained by photographing the photographing object with a photographing device.

Here, the object to be photographed can transmit at least part of light, such as a poster or a painting. In such a case, the degree of transmission of the light emitted from the light emitting unit varies depending on the color distribution (such as shading) and the material of the object to be photographed. In places where the intensity of light passing through the object to be photographed is strong, overexposure occurs when the object to be photographed is photographed by the photographing apparatus, and the corresponding part in the image data is whitened.

Thereby, it is possible to prevent such works from being voyeurized. In the following embodiment, the object to be photographed is a poster placed in a forehead, for example. In the following embodiments, similar constituent elements are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

(First embodiment)
FIG. 1 is a schematic side view showing the configuration of the apparatus according to the present embodiment.
The device 150 is configured to give a pattern shape to the shooting target in the image data obtained by shooting the shooting target 200 with the digital camera 300 (shooting device) by the light emitted from the light emitting unit 100. Here, the digital camera 300 can be configured to include an image sensor such as a charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS). The apparatus 150 in the present embodiment is configured to prevent the photographing target 200 from being photographed as it is by the general digital camera 300 having such a configuration.

  The light emitting unit 100 is arranged on the back side of the shooting target 200 and is configured to irradiate light from the back of the shooting target 200. The light emitting unit 100 is arranged to emit light in the direction of a viewing position where a viewer is supposed to view the shooting target object 200 via the shooting target object 200. Here, the light source 101 of the light emitting unit 100 is formed over the entire back surface of the photographing object 200. In FIG. 1, the light emitting unit 100 and the imaging target object 200 are illustrated apart from each other in order to show light rays, but the light emitting unit 100 may be provided in contact with the imaging target object 200.

The degree of transmission of the light emitted from the light source 101 of the light emitting unit 100 differs depending on the color distribution (such as shading) of the object 200 to be photographed. In places where the intensity of light transmitted through the subject 200 is strong, overexposure occurs when the subject 200 is photographed by the digital camera 300, and corresponding portions in the image data are whitened. On the other hand, in a place where the intensity of light transmitted through the photographing object 200 is weak, even if the photographing object 200 is photographed by the digital camera 300, the state is almost taken as it is. As described above, according to the apparatus 150 in the present embodiment, a pattern shape can be given to the imaging target in the image data captured by the imaging apparatus, depending on the difference in the degree of light transmitted through the imaging target 200. .

  The light source 101 of the light emitting unit 100 irradiates light having a wavelength outside the visible region. In this Embodiment, the light which the light source 101 of the light emission part 100 irradiates can be infrared rays (wavelength 0.75-1000 micrometers). The light source 101 can be, for example, a fluorescent lamp or a light emitting diode that emits infrared light.

  By irradiating such a light from the light emitting unit 100 and transmitting the photographing object 200, when the viewer views the photographing object 200 with the eyes, the light emitted from the light emitting unit 100 is visible. Therefore, the subject 200 can be viewed as usual. On the other hand, when the viewer tries to photograph the object 200 with the digital camera 300, overexposure occurs in a portion where the light transmittance is high, the corresponding portion in the photographed image is whitened and photographed, and the pattern shape is It will be in the granted state. In addition, when the viewer tries to photograph the object 200 while looking at the display of the digital camera 300, the image data that has passed through the image sensor of the digital camera 300 is displayed on the display. Further, it can be seen that a pattern shape is given to the photographing object 200 to be photographed. Therefore, it is possible to reduce the willingness of the viewer to photograph the object 200 to be photographed.

FIG. 2 is a diagram illustrating an object to be photographed when viewed with the eyes and when photographed with the digital camera 300.
FIG. 2A is a diagram showing the photographing object 200 when viewed with the eyes. Here, the photographing object 200 is a poster on which a picture of a flower is drawn. The photographing object 200 includes a light color portion and a dark color portion. Although not shown here, the light emitting unit 100 is disposed on the back surface of the photographing target 200. The light source 101 of the light emitting unit 100 is disposed over almost the entire surface of the photographing target 200. The light emitted from the light emitting unit 100 has a high transmittance in the light-colored portion of the subject 200 and has a low transmittance in the dark portion of the subject 200.

  FIG. 2B is a diagram illustrating image data 310 when the photographing target 200 is photographed with the digital camera 300. The image data 310 includes shooting object data 312. Here, the light-colored portion of the subject 200 is over-exposed by the digital camera 300 and becomes white because the transmittance of light emitted from the light emitting unit 100 is high. On the other hand, the dark color portion of the object 200 remains as it is because the transmittance of the light emitted from the light emitting unit 100 is low.

As described above, according to the device 150 in the present embodiment, when the photographing object 200 that is normally viewed when the viewer sees it with the digital camera 300 is photographed according to the lightness and darkness of the photographing object 200. As a result, a white portion is generated, and the image data of the object 200 cannot be obtained as it is. Thereby, even if the photographing target 200 for which voyeurism or the like is desired is photographed, it is possible to prevent the photographer from obtaining the image data as it is. In addition, when the digital camera 300 has a display and the viewer takes a picture of the subject 200 while looking at the display, the image data 310 as shown in FIG. 2B is displayed on the display. It is possible to reduce the willingness of the viewer to photograph the object 200 to be photographed.

The mask 110 is disposed between the light source 101 and the imaging target object 200. Part of the light emitted from the light source 101 passes through the mask 110 and is irradiated onto the object 200 to be photographed. In FIG. 5A, the light source 101, the mask 110, and the imaging target object 200 are illustrated separately to show light rays, but these may be provided so as to be in contact with each other.

FIG. 5B is a plan view showing the mask 110.
The mask 110 has a cut-out portion formed in the pattern shape 112. By disposing the mask 110 configured in this manner between the light source 101 and the photographing target 200, when the photographing target 200 is photographed by the digital camera 300, an image similar to that shown in FIG. Data 310 may be used.

According to the apparatus 150 in the present embodiment, a pattern shape can be given to the shooting target in the image data shot by the digital camera 300 depending on the difference in the degree of light transmitted through the shooting target 200. Thereby, it is possible to prevent the photographing object 200 that is desired to prevent voyeur photography or the like from being photographed as it is by the digital camera 300.

The light emitting unit 100 is arranged so that the light reflected on the reflecting member 120 is irradiated in the direction of the viewing position while irradiating the reflecting member 120 with light. The reflection member 120 can be configured by, for example, forming a reflection material on glass that covers the front surface of a poster placed in a forehead that is the photographing object 200.

FIG. 7 is a plan view showing the reflecting member 120.
The reflection member 120 has a pattern shape forming region 122 that has a reflectance that is different from that of the other regions with respect to the light emitted from the light emitting unit 100.

The other region is made of a material that does not reflect light from the light emitting unit 100. Further, both the pattern shape forming region 122 and other regions are made of a material that transmits visible light.

  As the reflective material, a material that reflects light emitted from the light emitting unit 100 and transmits visible light can be used. When the light emitted from the light emitting unit 100 is infrared, the reflective material can be a transparent heat ray reflective film. The heat ray reflective film is preferably colorless and transparent. The reflective material can also be constituted by a coating material obtained by making a semiconductor metal oxide into ultrafine particles and mixing it with a resin material such as acrylic or polyethylene.

FIG. 8 is a diagram illustrating the image data 310 when the digital camera 300 captures the imaging target 200.
In this way, by irradiating the reflecting member 120 having the pattern shape forming region 122 with light from the light emitting unit 100, the pattern shape is added to the shooting target data 312 of the image data 310 of the shooting target 200 shot with the digital camera 300. A pattern shape similar to that of the formation region 122 can be provided. Here, the pattern shape forming region 122 may have any shape, but may have a shape that reduces the willingness of a person who wants to photograph the object 200 to be photographed, such as a cross mark.
