Embodiment Construction

[0012] refer to figure 1 As shown, it is a schematic diagram of a preferred embodiment of the video surveillance light adjustment system of the present invention. The video surveillance light adjustment system 10 runs in a video server 11 . The video monitoring light adjustment system 10 generates a light adjustment signal according to the images collected by the camera 13 and sends the light adjustment signal to the light controller 12 so that the light controller 12 adjusts the light of the camera 13 and the fill light 14 . In this embodiment, the light controller 12 changes the amount of light entering the camera 13 by adjusting the aperture of the camera 13 . In other embodiments, the light controller 12 can adjust the light of the camera 13 in other ways, for example, by adjusting the shutter speed of the camera 13 to adjust the light of the camera 13 . The light controller 12 can be various types of control elements, such as single chip microcomputer, digital signal pr...

Abstract

The invention discloses a system for adjusting video monitoring light. The system comprises an image acquiring module for acquiring images in a monitoring spot, an image analyzing module for judging whether the brightness of the acquired images is dark or bright, and a signal generating module for generating a light adjusting signal for enhancing or weakening light and sending the light adjusting signal to a light controller so as to lead the light controller to adjust the light of a camera and a fill light based on the received light adjusting signal for enhancing or weakening the light. The invention also provides a method for adjusting the video monitoring light. The system and method provided by the invention can adjust the light of the camera and the fill light based on the environment changes, thus improving the quality of monitoring images.

Description

technical field [0001] The invention relates to a system and method for improving video surveillance image quality, in particular to a video surveillance light adjustment system and method. Background technique [0002] In many video surveillance occasions, video surveillance equipment needs to work around the clock. In order to capture clear images under different brightness conditions, it is necessary to control the light of the video surveillance equipment. At present, it is relatively simple to control the light of video surveillance equipment, for example, it is only possible to simply control the on and off of the supplementary light, which cannot meet the light control requirements under different brightness conditions. Contents of the invention [0003] In view of the above, it is necessary to provide a video surveillance light adjustment system, which can adjust the light of the camera and the supplementary light under different brightness conditions, so as to im...
