Abstract

The invention provides an image stabilization method for video images and a mobile terminal. The image stabilization method for the video image comprises the steps of in a video photographing process, obtaining first gyroscope information of a first moment corresponding to a current frame video image and second gyroscope information of a second moment corresponding to at least one frame video image before the current frame video image; carrying out image stabilization processing on the current frame video image according to the first gyroscope information and the second first gyroscope information, thereby obtaining a first image stabilized image; displaying the first image stabilized image in a viewfinder; obtaining third gyroscope information of a third moment corresponding to at least one frame video image after the current frame video image; and carrying out image stabilization processing on the first image stabilized image according to the third gyroscope information, thereby obtaining a second image stabilized image. According to the scheme provided by the invention, phased image stabilization processing is carried out on the video images, the instant output delay of the video images can be avoided, the visual experience of a user is improved, and the video effect of the finally output video image is effectively improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a video image stabilization method and a mobile terminal. Background technique [0002] At present, mobile terminals, especially hand-held mobile terminals, generally face the problem of image quality degradation caused by hand-shaking, abnormal movement and other reasons when shooting videos. In order to improve the quality of video images, image stabilization technology has been widely used in the video shooting process of various handheld mobile terminals. Among them, the most typical image stabilization technology is to use gyroscopes (Gyroscopes) to obtain changes in the position and posture of mobile terminals, and then apply them to image post-processing to eliminate the instability of video images caused by changes in the position and posture of mobile terminals. question. [0003] However, mobile terminals usually have normal movement and zooming when shooting v...
