Embodiment approach

[0134] In the first possible implementation, in the process of shooting the video, the camera sequentially captures n frames of original images to obtain the original video, where n≥2 and n is an integer; The frame intercepts partial images from the original image; obtains partial videos according to each partial image.

[0135] Wherein, the position of the predetermined clipping frame in each frame of the original image is the same. The size of the predetermined clipping frame may be equal to the size of the original image shrunk by a preset ratio factor, and the predetermined clipping frame may be located in a middle area of ​​the original image.

[0136] Certainly, in other possible implementation manners, the electronic device may also intercept a partial image from each frame of the original image according to a predetermined clipping frame when two frames or more than two frames of the original image are collected. Not specifically limited.

[0137] In the second possi...

Abstract

The invention relates to a video processing method and device and belongs to the technical field of image processing. The method comprises obtaining original video and local video corresponding to the original video, wherein the picture region of an i frame of the local image in the local video is the sub-region of the picture region of an i frame of the original image; detecting a shaking target image in the local video and calculating the target image offset adjusting amount; cutting a replacement image out of the original image corresponding to the target image according to the offset adjusting amount; replacing the target image with the replacement image. By means of the method and the device, the problem that video picture stability is affected due to the shaking of mobile terminals is solved; by post processing, the shaking target image is replaced by the replacement image, and accordingly, the video picture stability and the video quality are improved, and the video picture consistency obtained after shaking removal processing is guaranteed.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, in particular to a video processing method and device. Background technique [0002] Mobile terminals such as mobile phones, tablet computers, and smart cameras usually have a camera function, and the camera function is also one of the functions commonly used by users. [0003] However, this type of mobile terminal is a handheld device, and the hand of the user holding the mobile terminal will inevitably shake during the process of shooting a video, which leads to poor stability of the captured video picture. As the design of the body of the mobile terminal becomes thinner and lighter, the shaking will lead to worse stability of the video picture captured by the mobile terminal. Contents of the invention [0004] In order to solve the problem that the stability of a video image is affected by shaking of a mobile terminal, embodiments of the present disclosure provide a video ...
