Background

The image sensor of a film camera, which generates image signals from incident light, may have a two-dimensional matrix of light-sensitive sensor elements, in particular a color filter structure, for example arranged according to the Bayer pattern (RGGB). A motion picture camera may have an integrated objective lens (lens) for imaging a scene image onto an image sensor or an objective mount for holding an interchangeable objective lens. Each of the successive frames may be, for example, a respective full frame or half frame, which comprises only the complete image content and other half frames, in the production of a movie (also called cinematography), a large number of moving image sequences and usually also sound sequences associated with the moving image sequences are recorded first. Wherein the recorded image material and sound material are selected, processed and structured as part of the post-production to give the produced movie a final form. This kind of post production also is called the film clip, or synonymously is film montage, camera lens montage or arrangement, need shoot at night according to the script demand in some cases, but night because the light that the light causes to penetrate into the camera lens is not enough, lead to light sense component underexposure, the photographic effect is not good, current light filling lamp improves the illuminating effect mostly through multiunit light emitting source, multiunit light source shines not only the waste resource, can still produce a large amount of heats in the use, short service life, and because the scattering form of the light that every group light source jetted out is too, lead to the light intensity in light filling lamp middle part higher, higher illumination can lead to shooting light sense component overexposure after penetrating into the camera lens, cause the object of shooing unclear, therefore need us to design a light filling lamp light scattering device for shooting, solve these problems.
