Description

Camera lens capable of reducing video special effect production in later period
Technical Field
The present invention relates to the field of image pickup apparatuses, and in particular, to an image pickup lens that can alleviate post-production of video effects.
Background
In the production process of the film and television works, special effects are usually needed, wherein one special effect is a fish-eye effect, namely, the effect similar to the observation of a wide-angle lens is formed on the local part of a film and television picture, and actually, a collapse area is formed on the local part of the film and television picture, so that the peripheral pixels collapse towards the collapse area.
In contrast, in terms of hardware, currently, only fisheye lenses can be used, and currently, fisheye lenses are fixed, that is, only fisheye effects can be formed on the whole image or fixed parts of the image, but fisheye effects cannot be flexibly and randomly formed at various positions of the image according to needs. In order to form a dynamic fisheye effect at each position of an image, currently, only a software method can be used for post-processing a shot video picture, and since the video picture is composed of a large number of continuous frames of pictures, each frame of picture needs to be calculated and processed, the calculation amount is huge, and the processing difficulty is high.
Disclosure of Invention
In view of the above problems, it is an object of the present invention to provide a reflection-type special effect imaging lens that can flexibly and arbitrarily form a fisheye effect at each location of an image as needed on a hardware level to reduce a workload of a post-special effect production.
The technical scheme adopted by the invention for solving the technical problems is as follows: the reflection type special effect camera lens comprises a host; a fixed lens is arranged in front of the host; a special effect lens is arranged at the front end of the fixed lens and comprises a reflecting mirror surface forming an included angle of 45 degrees with the fixed lens, so that external scenes enter the fixed lens after being reflected by the reflecting mirror surface; the reflector comprises two transparent elastic membranes which are parallel to each other, and a mercury interlayer is formed between the two elastic membranes; an air nozzle is arranged behind the reflecting mirror surface and driven by a universal driving mechanism, so that the air nozzle can spray linear air flow to any position on the back surface of the reflecting mirror surface, and the reflecting mirror surface is arched forwards at the position sprayed by the air flow to form a local convex mirror.
Preferably, a rigid mesh plate is lined at the rear side of the reflector surface, and the rigid mesh plate forms a rigid support for the reflector surface so as to inhibit the reflector surface from deforming backwards and enable the linear air flow to penetrate through the rigid mesh plate and to be impacted to the back of the reflector surface.
Preferably, the size of the nozzle of the air nozzle is adjustable to adjust the deformation characteristic of the reflector surface, so as to adjust the range of the fisheye effect in the video picture.
The invention has the beneficial effects that: when the reflective special-effect camera lens is used for shooting a special-effect video of a fisheye, only the airflow of the air nozzle is required to be sprayed on the back surface of the reflecting mirror surface corresponding to the position where the special effect is required to be formed on a video picture, so that the corresponding area on the reflecting mirror surface is arched forwards under the action of the airflow to form a local convex mirror, and the local fisheye effect can be formed due to the wide-angle characteristic of the local convex mirror; with the free wandering of the airflow on the reflecting mirror surface, the fish eye effect can be freely formed at all positions of the video picture.

Fig. 1 is a schematic configuration diagram of an embodiment of the reflection type special effect imaging lens.
Fig. 2 is a schematic diagram of a partial convex mirror formed on the surface of a reflecting mirror in the reflection type special effect imaging lens.
Detailed Description
The invention is further illustrated with reference to the following figures and examples:
in the embodiment shown in fig. 1, the reflection type special effect imaging lens includes a main body 1; a fixed lens 2 is arranged in front of the host 1; the front end of the fixed lens 2 is provided with a special effect lens 3, the special effect lens 3 comprises a reflecting mirror 31 which forms an included angle of 45 degrees with the fixed lens 2, and external scenes enter the fixed lens 2 after being reflected by the reflecting mirror 31; the reflector 31 comprises two parallel transparent elastic membranes, and a mercury interlayer is formed between the two elastic membranes; an air nozzle 4 is provided behind the reflecting mirror surface 31, and the air nozzle 4 is driven by a universal driving mechanism 41 so as to eject a linear air flow to an arbitrary position on the back surface of the reflecting mirror surface 31 and to arch the reflecting mirror surface 31 forward at the position where the air flow is ejected, thereby forming a partial convex mirror 310 as shown in fig. 2.
In addition, in this embodiment, a rigid mesh plate 32 is further disposed on the rear side of the mirror surface 31, and the rigid mesh plate 32 forms a rigid support for the mirror surface 31 to suppress rearward deformation of the mirror surface 31, and enables a linear air flow to pass through the rigid mesh plate 32 and impinge on the rear surface of the mirror surface 31.
When the above-mentioned reflective special-effect camera lens shoots a fisheye special-effect video, it is only necessary to make the air flow of the air nozzle 4 spray on the back of the reflecting mirror 31 corresponding to the position where the special effect is required to be formed on the video picture, and make the corresponding area on the reflecting mirror 31 arch forward under the action of the air flow, so as to form a local convex mirror 310, and due to the wide-angle characteristic of the local convex mirror 310, a local fisheye effect can be formed; as the air flow freely moves on the reflecting mirror surface 31, the fisheye effect can be freely formed at any position of the video image.
In addition, the size of the nozzle of the air nozzle 4 is adjustable to adjust the deformation characteristic of the reflector 31, that is, when the nozzle is small, under the condition of the same air injection amount, the air flow is concentrated, so that the arching degree of the local convex mirror 310 is deep, the curvature is large, and the fisheye effect is concentrated and strong; when the nozzle is large, the range of the local convex mirror 310 is large, and the range of the fish eye effect is large and shallow; of course, if the jet opening is adjusted to be larger, the air injection amount is synchronously increased, so that the fish eye effect is large in range and strong.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, but rather as the subject matter of the invention is intended to cover all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.
