Abstract

The invention provides a method for dynamic enlarging display of video. The method comprises the steps of acquiring an enlarging gesture touch command in real time in a video play state; according to the generation position of the enlarging gesture touch command, acquiring an appointed enlarging area through calculation; extracting single-frame images of the appointed enlarging area successively; creating an enlarged video play window in a video play area outside the appointed enlarging area; enlarging the single-frame images of the appointed enlarging area to the size of the enlarged video play window and displaying the images in the enlarged video play window successively. The invention also provides a device for dynamic enlarging display of video. The device comprises an enlarging command acquiring module, an appointed enlarging area acquiring module, an image extraction module, a window creating module, an image enlarging module and a display module. The method and a device for dynamic enlarging display of video can perform partial enlargement on video and optimize the conventional video play modes.

Description

technical field [0001] The invention relates to the technical field of video processing, in particular to a method and device for dynamically zooming in and displaying video. Background technique [0002] In the past, when playing videos on smart devices (PCs, tablet computers, and smart phones), there was no function of partially zooming in on videos in real time. If when playing a video of a chemistry teacher doing a chemical experiment, it is difficult to see the chemical reaction picture clearly because of the small size of the test tube or other chemical equipment. A key area is dynamically enlarged and superimposed in the current video window, so that viewers can easily and quickly obtain a certain important video content for key viewing, which will bring better experience to viewers and It can improve the effectiveness of teachers' classroom experimentation. Contents of the invention [0003] In view of this, the purpose of the present invention is to propose a me...
