It is conceivable that the anti-reverse-light photographing apparatus provided by the present application further includes any necessary control device, fixing member, and the like. When the device is used, the device is connected with a fixed object according to the requirement, so that the camera lens surface of the camera body is opposite to an area to be shot. In the use, the luminance of the light that shines to the camera lens face is monitored in real time to illuminance sensor, and when illuminance was lower, the controller sent the signal to the light filter switch, and light filter sensor control polarization lens and perspective lens all shift out in the camera light path of making a video recording of camera body. At the moment, the reflected light rays of the shooting area all enter the shooting mirror surface, and the best shooting effect is ensured.
When this perspective mirror is for being provided with photochromic layer, strengthen the back when detecting illuminance gradually, illuminance satisfies photochromic's during the critical light intensity value of photochromic layer, the controller is to the light filter switch signals, in the light filter switch control perspective mirror gets into the light path of making a video recording of camera body, the photochromic layer of perspective lens can the colour deepen and reduce the light through rate, filters the light, can make the camera obtain the received light intensity of more suitable shooting, can obtain better formation of image effect.
When the perspective mirror is a blue glass sheet capable of cutting off infrared light, after the illuminance is gradually enhanced, the preset infrared light filtering illuminance threshold value is met, and the illuminance threshold value can be automatically set according to the shooting performance of the camera. The controller sends a signal to the optical filter switcher, the optical filter switcher controls the perspective mirror to enter a camera shooting light path of the camera body, and the blue glass sheet capable of cutting off the infrared light can effectively cut off the red light in the light so that the camera body can achieve a good shooting effect. The blue glass sheet capable of cutting off the infrared light can exit the light path at night, and the shooting effect of the camera at night is not affected.
When the illuminance is further enhanced and the condition that the light rays directly penetrate the camera body to form a backlight shooting state is judged, the controller sends a signal to the optical filter switcher, and the optical filter switcher controls the perspective lens to exit from a camera light path of the camera body and controls the inside of a camera light path of the camera body in the polarizing lens machine. The polarization lens can improve scenery image light directionality, and the polarization lens carries out directional processing to the image light that gets into, and only polarization direction can get into camera body light path of making a video recording with the part of polarization lens printing opacity axle direction syntropy in the image light, and the polarization glare of the multiple angle of other directions is then absorbed, and the surveillance image colour that obtains is more saturated, and the picture is more clear, makes camera imaging effect obtain obvious promotion.
When the light entering the camera body shooting optical path is detected to be gradually darkened, the different polarization lenses and the perspective lenses are controlled to be switched in the camera body shooting optical path through the controller according to the preset illuminance. When shooting at night, the polaroid and the perspective lens can be withdrawn from the camera body camera shooting light path, and the shooting effect at night is ensured.
In a word, the anti-reverse light image pickup device provided by the application has the advantages of simple and reasonable structure and strong reliability.
