Problems solved by technology

For this reason, a sun visor is generally installed above the lens of an outdoor camera at present. However, when the length of the sun visor extends forward is large, it will obviously affect the field of view of the camera, and when the length of the sun visor is short, it will affect the background in many cases. The shading effect of light is still weak

Embodiment Construction

[0013] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0014] exist figure 1 , figure 2 In the shown embodiment one, the high-definition outdoor camera includes a substrate 2 connected to the bracket 1, a lens 3 is arranged in front of the substrate 2, and a light shield 4 is arranged above the lens 3; the light shield 4 is composed of a liquid crystal Panel composition; the upper side of the lens 3 is provided with a photoelectric sensor 5 in the same direction as the lens 3; the photoelectric sensor 5 is coupled to the control module of the liquid crystal panel, so that the liquid crystal panel displays a black area from the root Extend forward until the lighting intensity of the photoelectric sensor 5 is less than the set value, or until the liquid crystal panel is all displayed in black (at this time, the shading area of ​​the shading plate 4 can no longer be increased).

Abstract

The invention provides a high-definition outdoor camera, which includes a base connected to a bracket, a lens is arranged in front of the base, and a shading plate is arranged above the lens; the shading plate is composed of a liquid crystal panel; A photoelectric sensor that is aligned with the lens orientation; the photoelectric sensor is coupled to the control module of the liquid crystal panel, so that the area displayed as black on the liquid crystal panel extends forward from the root until the lighting intensity of the photoelectric sensor is less than the set value, or until the LCD panel is completely black. The camera can adaptively weaken the background light to the lens, so that the clarity of the captured object image and the size of the shooting field of view can be kept in an optimal balance.

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 length of the sun visor extends forward is large, it will obviously affect the field of view of the camera, and when the length of the sun visor is short, it will affect the background in many cases. The shading effect of light is still weak. Contents of the invention [0003] In view of ...
