Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the embodiments and the accompanying drawings.

[0023] An embodiment of a device for automatically identifying candid shots provided by the present invention is as follows: figure 2 As shown, the light beam 7 emitted by the illumination source 1 is irradiated on the area 2 to be inspected, and the reflected light enters the camera 4 through the filter switch 3, and is converted into an electrical signal by the camera and output to the image processing in the form of image data. device 5. Wherein the illumination light source 1, the filter switcher 3, the camera 4 and the image processor 5 are all electrically connected to the control circuit 6, and are preferably wired. The camera 4 includes an imaging lens and a CCD or CMOS photosensitive element, which can image the incident light and convert it into image data, in which the brightness of each pixel is represented by a numerical value, and ...

Abstract

The invention discloses a device and a method of automatically recognizing a candid camera. The device comprises a lighting source, a filter switcher, an image pickup device, an image processor and a control circuit, wherein the lighting source emits visible light and infrared light to irradiate on a to-be-detected area; the filter switcher can switch filters in turn to the front end of the image pickup device to enable the image pickup device to acquire visible light and infrared light images; the image processor compares a brightness difference between the infrared light image and the visible light image and a threshold, and whether a candid camera exists is judged; and the control circuit sends a control instruction to the above parts according to a self-stored program. Through the device and the method of the invention, an illegal photographing behavior can be recognized in an unattended and real-time mode, and the safety of the privacy of people and trade secrets can be effectively protected.

Description

technical field [0001] The present invention relates to the field of information security, in particular to a device and method for automatically identifying sneak shots. Background technique [0002] With the development of semiconductor image sensors, more and more electronic products are equipped with camera and camera functions, which not only enriches people's life and entertainment, but also leads to more and more leaks of personal privacy and business secrets. Danger. Especially in confidential occasions, a convenient and effective method is needed to stop illegal candid photography. [0003] Nowadays, the detection of sneaky cameras is more common to use human eyes to check the reflective points after being irradiated by strong light. It can only check the existence of fixed lenses within a certain range, such as hidden cameras in hotel rooms and locker rooms, etc., and requires human eyes. Participation in the whole process does not work for temporary, randomly mo...
