Description

A kind of pick-up lens and its working method
Technical field
The present invention relates to picture pick-up device fields, particularly, are related to a kind of pick-up lens and its working method.
Background technique
In the manufacturing process of films and television programs, it usually needs use special efficacy, one of special efficacy is fish eye effect, that is, Make tv screen is partially formed effect similar with wide-angle sem observation, is actually to be partially formed collapse in tv screen Region makes the collapse into the collapse region of the pixel on periphery.
In this regard, fish eye lens can only be used at present in hardware aspect, and current fish eye lens is fixed, i.e., only It can make the fish eye effect that is partially formed fixed on whole picture image or image, and flexibly optionally cannot make image as needed Everywhere in form fish eye effect.In order to make to form dynamic fish eye effect everywhere in image, software approach pair can only be passed through at present The video pictures already taken the photograph carry out post-processing, since video pictures are that have the picture of continuous a large amount of frame numbers to constitute, because This needs that each frame picture is calculated and handled, and calculation amount is huge, and processing difficulty is larger.
Summary of the invention
In view of the above-mentioned problems, the purpose of the present invention is to provide a kind of reflection-type special efficacy pick-up lens, which can be Hardware view flexibly optionally makes to form fish eye effect everywhere in image as needed, to mitigate the work of later period special effect making Burden.
The technical solution adopted by the present invention to solve the technical problems is: the reflection-type special efficacy pick-up lens includes host； Fixed lens are equipped in front of the host；The fixed lens front end is equipped with a basic lens, and the basic lens include one Block and the fixed lens are in the mirror surface of 45 degree of angles, keep extraneous scene described via entering after mirror surface reflection Fixed lens；The mirror surface includes two pieces of transparent elastic diaphragms being parallel to each other, and forms one between two pieces of flexible sheets A mercury interlayer；The rear of the mirror surface is equipped with an air nozzle, and the air nozzle is driven by universal driving mechanism, makes it Straight air stream can be ejected into any position at the mirror surface back side, and make mirror surface in the position by jet-impingement It sets and arches upward forwards, form local convex mirror.
Preferably, the rear side lining of the mirror surface sets one block of rigid web plate, the rigidity web plate is to the reflecting mirror Face forms rigidity and sets off, and to inhibit mirror surface deformation backward, and straight air stream can be made to pass through rigid web plate and rush and be mapped to reflection The back side of mirror surface.
Preferably, the spout of the air nozzle is adjustable, to adjust the deformation characteristics of the mirror surface, to adjust Save the range of fish eye effect in video pictures.
The beneficial effects of the present invention are: the reflection-type special efficacy pick-up lens need to only make when shooting flake special efficacy video The jet-impingement of air nozzle makes reflecting mirror at the back side of mirror surface corresponding with the formation position of special efficacy needed for video pictures Corresponding region is arched upward forward under airflow function on face, forms local convex mirror, due to the wide-angle characteristic of local convex mirror, i.e., Local fish eye effect can be formed；With free migration of the air-flow on the mirror surface, fish eye effect can be made to be freely formed Everywhere in video pictures.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of one embodiment of this reflection-type special efficacy pick-up lens.
Fig. 2 is the schematic diagram for the local convex mirror that mirror surface surface is formed in this reflection-type special efficacy pick-up lens.
Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples:
In the embodiment shown in fig. 1, which includes host 1；Fixed mirror is equipped in front of the host 1 First 2；2 front end of fixed lens is equipped with a basic lens 3, and the basic lens 3 include one piece and are in the fixed lens 2 The mirror surface 31 of 45 degree of angles enters the fixed lens 2 after reflecting extraneous scene via the mirror surface 31；It is described Mirror surface 31 includes two pieces of transparent elastic diaphragms being parallel to each other, and forms a mercury interlayer between two pieces of flexible sheets； The rear of the mirror surface 31 is equipped with an air nozzle 4, and the air nozzle 4 is driven by universal driving mechanism 41, allowed to Straight air stream is ejected into any position at 31 back side of mirror surface, and makes mirror surface 31 in the position by jet-impingement It sets and arches upward forwards, as shown in Fig. 2, forming local convex mirror 310.
In addition, the rear side of the mirror surface 31, which also serves as a contrast, sets one block of rigid web plate 32, the rigidity web plate in the present embodiment 32 pairs of mirror surfaces 31 form rigidity and set off, and to inhibit the deformation backward of mirror surface 31, and it is rigid that straight air stream can be made to pass through Property web plate 32 and rush and be mapped to the back side of mirror surface 31.
Above-mentioned reflection-type special efficacy pick-up lens only need to make the jet-impingement of air nozzle 4 exist when shooting flake special efficacy video The back side of mirror surface 31 corresponding with the formation position of special efficacy needed for video pictures, makes corresponding region on mirror surface 31 It arches upward forward under airflow function, office can be formed by forming local convex mirror 310 due to the wide-angle characteristic of local convex mirror 310 Portion's fish eye effect；With free migration of the air-flow on the mirror surface 31, fish eye effect can be made to be freely formed in video Everywhere in picture.
In addition, the spout of the air nozzle 4 is adjustable, to adjust the deformation characteristics of the mirror surface 31, that is, spout When smaller, in the case of same jet amount, due in air flow collection, making arching upward for the local convex mirror 310 deep, curvature compared with Greatly, fish eye effect is more concentrated and strong；And spout it is larger when, then the range of local convex mirror 310 is larger, fish eye effect range It is big and plain；Certainly, such as while spout tunes up, synchronous to increase jet amount, can making fish eye effect, not only range is big, but also more strong It is strong.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and Within principle, made any modification, equivalent replacement be should all be included in the protection scope of the present invention.
