Abstract

The present invention provides a method for stabilizing a video image and a mobile terminal, wherein the method for stabilizing a video image includes: acquiring the first gyroscope information at the first moment corresponding to the video image of the current frame during the video shooting process and the second gyroscope information at the second moment corresponding to at least one frame of video image before the current frame video image, according to the first gyroscope information and the second gyroscope information, perform image stabilization processing on the current frame video image to obtain the first An image stabilization image, displaying the first image stabilization image in the viewfinder frame, obtaining the third gyroscope information at the third moment corresponding to at least one frame of video image after the current frame of video image, and according to the third gyroscope information, the first An image stabilization process is performed on a stabilized image to obtain a second image stabilized image. According to the solution of the present invention, through the phase-by-stage image stabilization processing of video images, it is possible to avoid immediate output delay of video images, improve user visual experience, and effectively improve the video effect of final output video images.

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...
