The invention discloses a light supplementing system and a light supplementing lamp, which relate to the technical field of optics, and solve the technical problems that glare is generated due to light supplementing, the quality of a photographed image is poor, and the dynamic range of light supplementing in the prior art is narrow. The light supplementing system at least comprises a light supplementing lamp composed of a plurality of light emitting microstructures and an image acquisition and processing control device. The image acquisition and processing control device is used for acquiring image information of a shot object in a visual field in real time, determining a corresponding to-be-processed area meeting a preset condition in an image, determining a real-time distance between the shot object and the light supplementing lamp, determining the light-emitting state of each light-emitting microstructure according to the real-time distance and the to-be-processed area, generating a control signal for controlling the light-emitting state of each light-emitting microstructure to change, and sending the control signal to the light supplementing lamp; and the light supplementing lamp is used for controlling the light-emitting state of each corresponding light-emitting microstructure to change according to the control signal.
Description
technical field [0001] The invention relates to the field of optical technology, in particular to a supplementary light system and a supplementary light lamp. Background technique [0002] The monitoring system is one of the most widely used systems in production and life. The most important point of video monitoring is to be able to clearly reflect the images of the monitoring terminal. , The distance between the subject and the camera and the fill light varies for various reasons, resulting in some areas of the image being overexposed, and some areas being completely black, which seriously affects the image quality. [0003] At the same time, the supplementary light of the prior art camera can produce dazzling or glare effects. If the vehicle or pedestrians are captured, it is easy to cause visual interference to drivers, passengers and pedestrians, and there is a potential safety hazard. [0004] In addition, the current smart fill light cannot achieve area fill light or...
