Abstract

The invention provides a camera shooting brightness control method, system and device and a medium, and the method comprises the steps: obtaining the brightness of a visible light image, carrying outthe face detection of the visible light image, and obtaining the face region brightness of a corresponding infrared light image; performing exposure control on an image sensing unit according to the visible light image brightness and the infrared light image face area brightness. According to the invention, the exposure precision can be effectively improved through brightness feedback of infraredand visible light images.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a camera brightness control method, system, equipment and medium. Background technique [0002] At present, the mainstream technology of living body detection is through binocular cameras, one RGB camera mainly uses visible light for supplementary light, and one infrared camera mainly uses infrared supplementary light for supplementary light. If the two images are controlled separately, when the scene changes, it is easy to have the problem of overexposure or insufficient fill light. Contents of the invention [0003] In view of the above existing problems in the prior art, the present invention proposes a camera brightness control method, system, device and medium, which mainly solve the problems of overexposure or insufficient light supplement. [0004] In order to achieve the above objects and other objects, the technical solutions adopted by the present invention ar...
