Image anti-shake method and device, electronic equipment and storage medium

Abstract

The invention discloses an image anti-shake method and device, electronic equipment and a storage medium. When the jitter frequency is changed from the first frequency to the second frequency, the target focal length, the target cutting proportion and the target magnification factor at the second frequency can be determined according to the first cutting proportion, the first magnification factor,the first focal length and the first field angle at the first frequency; and then image anti-shake processing is carried out according to the target focal length, the target cutting proportion and the target magnification factor. According to the image anti-jitter method provided by the invention, anti-jitter processing can be carried out in a self-adaptive jitter frequency manner; different cutting proportions are used according to different frequencies, so that the anti-shake effect is good, the cut image is amplified by using different amplification factors according to different frequencies, and the consistency of the view field angles of the image and the consistency of the size of an object in the image under different frequencies are ensured.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image anti-shake method, device, electronic equipment and storage medium. Background technique [0002] At present, with the intelligent development of surveillance cameras, customers have higher and higher requirements for picture quality. In the actual use environment, there may be some installation reasons (not fixed firmly) or external force reasons (wind blowing) of the camera, which may cause the image to shake. In order to avoid the phenomenon of screen shaking, anti-shake technology is generally used. The current conventional anti-shake technology is a combination of GME (Global Motion Estimation) algorithm technology and gyroscope algorithm technology. In this technology, the gyroscope algorithm technology is used to judge whether the foreground is moving or the camera is moving, and at the same time, the output jitter frequency is fed back, which i...

Problems solved by technology

[0004] Embodiments of the present invention provide an image anti-shake method, device, electronic equipment, and storage medium to solve the problem of sacrificing the field of view in a low-jitter frequency environment in the prior art because the cropping ratio is the same as that in a high-jitter frequency environment. angle problem
