Abstract

The invention relates to the technical field of video playing, and particularly relates to a video image processing method and device. The method comprises the steps of receiving a first sliding signal and a second sliding signal, wherein the first sliding signal comprises a first initial touch signal and a first ending touch signal, and the second sliding signal comprises a second initial touch signal and a second ending touch signal; determining a to-be-zoomed area of a playing video source according to the first initial touch signal and the second initial touch signal; determining a target area after the to-be-zoomed area is zoomed according to the first ending touch signal and the second ending touch signal; and drawing a video image in the to-be-zoomed area to the target area to play. Through the video image processing method and device, a user can select the area for zooming and the target area after being zoomed according to the need; when the video image is zoomed out to play, no black background is generated; when the video image is zoomed in, contents of other areas can be viewed by comparison; and thus, the user demand is met, and the user experience is greatly improved.

Description

technical field [0001] The invention relates to the technical field of video playback, in particular to a video image processing method and device. Background technique [0002] With the continuous development of video playback technology, the proportion of time people spend browsing videos in their lives has increased significantly. When browsing a video, sometimes the video is enlarged or reduced according to different needs. For example, in order to adjust the image in real time and observe the details of a certain area, the video image of the area needs to be enlarged. [0003] At present, the function of enlarging or reducing the video image usually uses digital zoom technology to process the video image. Since there is no uniform standard for the digital zoom image in the industry, the current existing method is to use the entire video image as a An object is enlarged or reduced, so as to realize the enlargement or reduction of a certain part of the video image.
