It takes pictures, record a video, duplicating, network is faxed without paper, makes the operations such as e-book, cutting edge righting.Its perfect solution allows office
It is lighter, faster, more environmentally friendly.All trades and professions are widely used at present, for scanning papery manuscript, acquire certificate and portrait
Information.In the environment of dark, the light compensating lamp progress light filling that high photographing instrument needs dependence camera included when shooting, but by
It is circular diverging hot spot in the light of light compensating lamp, when it is radiated at shooting platform, light has more partial illumination to shooting
The outside of platform, so that light source cannot be fully utilized, while the light illumination at edge is also not so good as the illumination at center, from
And light filling can be caused uneven.
Utility model content
To solve the above problems, the purpose of this utility model is to provide one kind can guarantee that light source makes full use of and light filling phase
To uniform high photographing instrument.
The utility model realized by following technical measures, it is a kind of can abundant and relatively uniform light filling high photographing instrument, packet
The shooting platform for placing shooting object is included, shooting arm is provided with above the shooting platform, is disposed an outwardly facing on the shooting arm
The supplementary lighting sources and camera lens of platform are shot, the position of the shooting arm installation supplementary lighting sources is set as bucket shape inner groovy, the bucket shape
The bottom of inner groovy is equipped with supplementary lighting sources, is covered with a lens outside the supplementary lighting sources, the shape of the bucket shape inner groovy and
Depth be set as lens transmitting light through bucket shape inner groovy it is each while be radiated at after receiving light shoot platform four while in.
The bucket shape inner groovy is arranged at the rear of camera lens as a preferred method, and the bucket shape inner groovy is towards camera lens
Direction on one side gradient be more than remote camera lens while gradient, the gradient of the bucket shape inner groovy dual side-edge is symmetrical.
The depth of the bucket shape inner groovy is 1-35mm as a preferred method,.
The surface of the bucket shape inner groovy is diffusing reflection as a preferred method,.
The position of central point of the optical center point to bucket shape inner groovy is 5-200mm as a preferred method,.
The lens are convex lens as a preferred method, and fluted and grid is arranged in the one side towards supplementary lighting sources
Line.
The supplementary lighting sources are LED light as a preferred method,.
The optical sensor of acquisition ambient light is additionally provided on the shooting arm as a preferred method,.
The utility model opens supplementary lighting sources when extraneous ambient light is inadequate, since supplementary lighting sources are arranged in bucket shape
The bottom of inner groovy, so the light that supplementary lighting sources are dissipated by lens makes it only be irradiated to bat after light is received on each side of bucket shape inner groovy
It takes the photograph in four sides of platform, to ensure that making full use of for light source is relatively uniform with light filling.
