Abstract

The invention discloses a display device and a video picture zooming method. The method comprises the steps: updating a user layer picture according to a first zooming rule after a controller of the display device receives an instruction for amplifying a video picture, obtaining the position information of a transparent window in a user layer in a preset time period, and generating a second zooming rule; controlling the video picture to be amplified according to the second scaling rule. As the position information of the transparent window corresponds to the preset display parameter of the video picture in the preset time period in the preset time period, the position information of the transparent window at a certain time point in the future can be predicted according to the position information of the transparent window in the preset time period; in this way, the display parameters, namely the second scaling rule, of the to-be-displayed video image at a certain time point in the future are predicted, then the to-be-displayed video image can be cached in advance, therefore, delayed display of the video image due to caching time consumption and other reasons is avoided, the phenomena of edge cutting and edge blackening are avoided, and the visual experience of a user is more friendly.

Description

technical field [0001] The present application relates to the technical field of display image zooming, and in particular to a display device and a method for zooming a video image in a user interface presented by the display device. Background technique [0002] With the popularity of the Internet and smart terminals, the channels and ways for users to watch video programs are becoming more and more extensive. For example, various video display applications such as iQiyi Video and Tencent Video are installed on devices such as smart TVs or mobile phones, and users can select and watch videos by running the display applications on the device. [0003] The user interface usually includes a user layer (UI layer) and a video layer (Video layer). The user layer is provided by the browser to provide video introduction and other information, while the video layer is used to display frame-by-frame video images. At present, the video display application also provides a zoom functio...
