DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

1 is a system block diagram of a secretly preventing camera device 10 according to an embodiment of the present invention.

1, the camera device 10 includes a light emitting unit 100, a control unit 200, and a power source unit 300.

First, the light emitting unit 100 uses red light, green light, blue light, and infrared light to distort an image or a moving image collected by the image sensor of the camera.

The controller 200 controls whether the red, green or blue light of the light emitting unit 100 is output so as to operate in one of the general illumination mode and the confusion prevention mode according to a user's input. In the unlikely operation mode, the controller 200 performs at least one of the control of the illuminance of the red light, the green light, and the blue light output from the light emitting surface 110 and the control of the blink period of the red light, the green light, and the blue light .

The power supply unit 300 supplies a direct current to the controller 200 and the light emitting unit 100. In this case, the power supply unit 300 may include a converter (not shown) that can convert the alternating current supplied to the home to direct current, and may be provided to supply current based on the power required for the light emitting unit 100 .

2A is a diagram showing a configuration of a light emitting unit 100 in a secret camera preventing apparatus 10 according to an embodiment of the present invention and FIG. 2B is a diagram showing a configuration of a secret camera preventing apparatus 10 according to an embodiment of the present invention, Emitting portion 103 according to the second embodiment of the present invention.

2A, the light emitting unit 100 of the invisible camera prevention apparatus 10 includes a first light emitting unit 101 that emits infrared rays, and a second light emitting unit 101 that emits at least one of three primary colors of red light, green light, and blue light And a second light emitting portion (103).

At this time, the first light emitting unit 101 and the second light emitting unit 103 operate independently of each other. That is, the operation of the first light emitting portion 101 to emit infrared rays and the operation of the second light emitting portion 103 to emit light of at least one of the three primary colors do not affect each other and operate independently of each other.

2B, the second light emitting unit 103 of the invisible camera prevention apparatus 10 includes first to fifth light emitting surfaces 103a, 103b, and 103c capable of irradiating light in five directions, 103c, 103d, 103e. Accordingly, the light emitting unit 100 can propagate the light evenly to the object, and the light is prevented from concentrating only in a specific direction by the light condensing device. However, this is only an embodiment, and the number of light emitting surfaces can be changed.

Each of the light emitting surfaces 103a, 103b, 103c, 103d, and 103e includes three LEDs for emitting light of three primary colors, that is, three cells capable of emitting light of three primary colors. At least one of the three cells is provided on each of the light emitting surfaces 103a, 103b, 103c, 103d, and 103e, and each cell is controlled by the control unit 200 for blinking. The LEDs provided on the respective light emitting surfaces 103a, 103b, 103c, 103d, and 103e serve to generate light by the blinking of cells divided by the viewing angles of light . Each cell is provided so as to independently irradiate light of each wavelength. At this time, the blinking period of the red light, the green light, and the blue light may vary according to the color.

Specifically, the second light emitting unit 103 uses three cells, i.e., the first cell to the third cell, by wavelength. The wavelengths of red, green, and blue light are 630-700 nm, 500-550 nm And a wavelength in the range of 440-460 nm. The light recorded on the image sensor in accordance with the blinking period is photographed in a state in which any one of the three primary color combinations is excluded, resulting in image distortion.

Recently, an image sensor of a digital camera uses a light inputted for a specific time slot (5, 10, 15 ms) separately from the brightness of light incident to each frame Three wavelengths (Red, Green, Blue) are stored separately.

(MP4, AVI, MOK etc.) in which the above operation is performed 30 times or more than 60 times per second to make data through a specific compression process (MP4, AVI, MOK etc.) When the cells emit light at the same time, they appear as transparent white like the sunlight, and all objects have their own colors. For example, a red rose appears red because it reflects only the red wavelength and absorbs the remaining wavelength.

However, if three cells are divided into three wavelengths and time-division is performed and light is emitted through each of the three cells, if the wavelength reflected by the subject and the specific time are sampled, only light of a different wavelength I will accept it. Specifically, when only the red light and the green light are to be emitted from the three cells in the frame 1, since there is no wavelength for the blue light, there is distorted information having no wavelength for the blue light, and only the red light and the blue light In the case of emitting light, since there is no wavelength for green light, it has distorted information with no wavelength for green light. That is, as the light source is constituted by at least one of the three cells per frame actually photographed, each frame has a different color. Thus, the image of the subject can be distorted.

FIG. 3 is a view showing an operation scenario of the second light emitting unit 103 in the secret camera preventing apparatus 10 according to the embodiment of the present invention, which is only an example, and is not limited thereto.

First, each period can be divided into four frames, and each frame can be divided at a ratio of 3: 5: 7: 3 to 4: 6: 8: 1. However, the present invention is not limited thereto. In addition, two to three colors are sequentially wiped out in each frame. Also, the turn-on delay is variable in each cycle, the turn-on point of each color is changed every cycle, and the turn-on / off value for each wavelength is constantly increased or audited in each frame.

3, the turn-on delay is 1, the main color is red, the turn-on time of the main color is 5, the sub color is blue, the sub color is turned on in the frame 1 of the first period Time is 2 and off interval is 3. In the frame 2 of the second period, the turn-on delay is 2, and the time when the red is turned on is increased by 1. In addition, the red color is 6, the blue color is 3, and the off-period decreases to 1 as the turn-on time increases.

When the turn-on delay and the turn-on time are changed by 0.01 in the first cycle to the second cycle, the number of turns is changed from 100 to the second cycle in the first cycle. The change from the second cycle to the first cycle is again reduced by 0.01 and returns to 100 changes.

Assuming that Frame 1 is composed of 9 spaces, Frame 2 is composed of 10 spaces, Frame 3 is composed of 10 spaces, Frame 4 is composed of 6 spaces, Frame 1 has 11 spaces, Frame 2 has 10 spaces, Frame 3 has 9 spaces And the first change is repeated.

On the other hand, the first light emitting unit 101 is for image distortion of a spy camera not equipped with an infrared filter, and functions as a focusing function of the camera which focuses the infrared light by operating only the infrared light source on / . In the unintentional mode, that is, in the infrared ray photographing mode, the image is distorted. At this time, the period in which the infrared light source is turned on / off varies in a variable manner.

If the pixel portion of each cell changes periodically, if the data distortion occurs at the edge portion in the operation for capturing the focus of the camera, the focus can not be adjusted and the image is captured by the image sensor of the camera Resulting in distorted images.

The first light emitting portion 101 and the second light emitting portion 103 each have at least one light emitting surface, and each light emitting surface adjusts the light emission angle using the light collecting device to adjust the contrast ratio of the light reflected on the subject. At this time, the light emitted from the light emitting surface is emitted only in a specific direction through the light collecting device, and the emitted angle is made within 10 degrees.

FIG. 4A is a view showing an image taken when a secret camera prevention apparatus 10 according to an embodiment of the present invention is used in a general illumination mode, and FIG. 4B is a view showing a secret camera prevention apparatus 10 according to an embodiment of the present invention. Is used as the invisible mode.

Referring to FIG. 4A, in a general illumination mode, a state of using a normal fluorescent lamp is obtained, and even if an image or a moving picture is photographed by using a camera, an undistorted image can be obtained. On the other hand, FIG. 4B shows a distorted image photographed when the invisible mode is used, so that the image collecting operation by the camera itself can be hindered.

However, the above-described distortion of the image is limited to the image by the camera. Even in the case where the secret camera preventing apparatus 10 according to the embodiment of the present invention is used in the confusion prevention mode, You can recognize objects as if they were placed on.

The spoofing prevention apparatus 10 according to the embodiment of the present invention may distort the process of extracting each wavelength from the image sensor through irregular changes in the wavelength and intensity of light input from the subject to the image sensor, And the like.

Specifically, by controlling the emission angle of each single-wavelength blinking, the illuminance change, and the light-emitting surface of the light-collecting device, the auto focus operation of the digital camera is interfered with, thereby hindering the measurement of the focal distance from the object. It can interfere with focusing. Also, the intensity value of the light can be distorted at the time of extracting the input value of the image sensor by the change of the intensity of light for each wavelength of each cell. If there is no correction circuit in the digital camera, the value input in the specific time slot for each wavelength continuously changes according to the above process, so that a certain value can not be extracted for each wavelength. This process prevents the proper gain value from being maintained at the time of gain adjustment for each wavelength, even if the digital camera has an image correction circuit.

Although the present invention has been described with reference to preferred embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It is not intended to limit the scope. It is to be understood by those skilled in the art that other modifications based on the technical idea of the present invention are possible in addition to the embodiments disclosed herein.
