Embodiment 1

[0012] exist figure 1 In the shown embodiment one, the self-adjusting outdoor camera includes a base 1 horizontally fixed on the building, and the bottom of the base 1 is provided with an inclined downward lens 2; the outside of the lens 2 is surrounded by a The hemispherical transparent cover 3 on the base 1; the transparent cover 3 is made of photochromic glass, and the transparent cover 3 is divided into a transparent ring 31 and a transparent bottom that are bonded to each other by a group of horizontal planes from top to bottom. 32, so that the colors of the adjacent transparent rings 31 do not affect each other, that is, when the transparent ring 31 above is subjected to solar radiation and changes color, it does not affect the color of the transparent ring 31 below, and the process of each transparent ring 31 being illuminated and changing color is mutual. independent.

[0013] In the aforementioned camera head, the thickness of the transparent cover 3 is 1mm-1.5mm; th...

Embodiment 2

[0016] for figure 2 The shown embodiment two differs from embodiment one in that: the outside of the transparent cover 3 is also close to one layer of refraction layer 4; thus, according to geometrical optics, for the sunlight on the top of refraction layer 4, Because the angle of incidence is small, after the incident light is deflected by the refraction layer 4, it enters the transparent cover 3 at an angle closer to the vertical, so that the transparent ring on the top of the transparent cover 3 obviously changes color; , because the angle of incidence is relatively large, partial total reflection will be produced on the interface between the refraction layer 4 and the transparent cover 3, so that the transparent ring at the middle and lower part of the transparent cover 3 will be lighter in color.

Abstract

The invention provides a self-regulating outdoor camera. The outdoor camera comprises a base horizontally fixed on a building, an inclined downward lens is arranged at the lower part of the base; a hemispherical transparent hood fixed on the base surrounds the external of the lens; the transparent hood is made of photochromic glass, and the transparent hood is divided into a transparent ring and a transparent bottom mutually adhered by a group of horizontal plane from top to bottom, so that the colors of the adjacent transparent rings are free from influencing each other. The camera can adaptively weaken the background illumination irradiating to the lens, thereby improving the definition of an image region in the premise of sacrificing the view as little as possible.

Description

technical field [0001] The invention relates to the field of security monitoring, in particular to an outdoor camera. Background technique [0002] For the current outdoor cameras, it is generally faced with the problem of strong backlight, that is, when the direction facing the lens has a strong background light, such as when the camera is facing the sun, the brightness of the captured object is extremely low, and the image The processing module can only increase the overall brightness of the ingested image, and the adjusted image has very limited clarity, even blurred. For this reason, a sun visor is generally installed above the lens of an outdoor camera at present. However, when the area of ​​the sun visor is large, it will obviously affect the field of view of the camera. weak. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a self-adjusting outdoor camera, which can adaptively weaken the background...
