Lens type special effect camera lens

Abstract

The invention provides a lens-type special-effect camera lens, which includes a host; a fixed lens is arranged in front of the host; A transparent flexible planar diaphragm parallel to the planar glass; a liquid chamber is formed between the planar glass and the planar diaphragm, and the liquid chamber communicates with an elastic chamber whose volume can expand and contract in the special effect lens. The liquid chamber, The elastic cavity is filled with transparent liquid; the special effect lens is also equipped with an air nozzle that can eject a straight air flow, and the air nozzle is assembled on the electronically controlled mechanical arm, and the electronically controlled mechanical arm is controlled by the controller. Next, the airflow ejected from the air nozzle can be directed to any position on the surface of the planar diaphragm. The lens can flexibly and arbitrarily form a fisheye effect on various parts of the image at the hardware level, so as to reduce the workload of post-production special effects.

Description

technical field [0001] The present invention relates to the field of camera equipment, in particular, to a camera lens. Background technique [0002] In the production process of film and television works, it is usually necessary to use special effects, one of which is the fish-eye effect, that is, to make the part of the film and television picture form an effect similar to that observed with a wide-angle lens, in fact, it is to form a collapsed area in the part of the film and television picture , so that the surrounding pixels collapse into the collapsed area. [0003] In this regard, in terms of hardware, only fisheye lenses can be used at present, and the current fisheye lenses are fixed, that is, only the entire image or a fixed part of the image can form a fisheye effect, and cannot be flexibly adjusted according to needs. Optionally create a fisheye effect anywhere in the image. In order to form a dynamic fish-eye effect in every part of the image, at present, the ...

[0003] In this regard, in terms of hardware, only fisheye lenses can be used at present, and the current fisheye lenses are fixed, that is, they can only form a fisheye effect on the entire image or a fixed part of the image, and cannot be flexibly adjusted according to needs. Randomly fisheye effect anywhere in the image

In order to form a dynamic fish-eye effect in every part of the image, at present, the post-processing of the captured video images can only be done through software methods. Since the video images are composed of a large number of consecutive frames of pictures, it is necessary to process each One frame of picture is calculated and processed, the amount of calculation is huge, and the processing is difficult
