A supplementary light device and photographing equipment

Abstract

The invention discloses a supplementary light device and a photographing device, which are used to solve the technical problem in the prior art that when photographing an object, the brightness contrast of the object surface in the longitudinal direction and the lateral direction is large, and glare is prone to occur. Including: at least two supplementary light modules, used to supplement light on the shooting object of the shooting device; the at least two supplementary light modules are arranged in an array according to the preset optical axis gradient rule to form the supplementary light device, so that each supplementary light module can perform uniform supplementary light on different areas of the subject; wherein, the optical axis gradient rule is to allow the optical axes of all supplementary light modules to intersect at an intersection point along the extension line of the light source direction , and the included angles between the optical axes of any two adjacent supplementary light modules are equal, and all the supplementary light modules have the same beam angle and different optical axes.

Description

technical field [0001] The invention relates to the monitoring field, in particular to a supplementary light device and a photographing device. Background technique [0002] In the field of monitoring, when shooting equipment such as video surveillance equipment, cameras, etc. shoot objects, due to the different shooting angles and ambient light, the captured images will be unclear. fill light. [0003] In the prior art, the fill light can usually only perform differential fill light in the depth direction or differential fill light in the center of the image and the annular area around the image. When the supplementary light in the prior art is used to supplement light on an object, there is often a problem of excessive brightness contrast on the surface of distant and near objects horizontally or vertically, and then the problem of loss of camera image details occurs. Moreover, the existing white light technology cannot independently control the intensity of the suppleme...
