Picture rendering method, device and mobile terminal

Abstract

The invention discloses a picture rendering method and device and a mobile terminal.The method comprises following steps: detecting pictures to be rendered as non-coding pictures by rendering threads for rendering web pages, creating picture coding tasks so that coding threads are used for coding pictures pictures according to image coding tasks for pictures; obtaining information on pictures; and rendering pictures coded by the coding threads according to obtained picture information. The picture rendering method, device and the mobile terminal have following beneficial effects: due to the fact that independent decoding threads are utilized for picture decoding such that threads for rendering can assign decoding tasks for coding threads when non-coding pictures are detected and coding threads are used for decoding pictures which are not decoded by detection; threads for rendering can perform rendering operation on elements on a next page; therefore, picture decoding operation is not linked to threads for rendering so that burden of threads for rendering is relieved; rendering speed of web pages is increased; and jamming phenomena during webpage browsing are effectively avoided.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and more specifically, to a picture rendering method, device and mobile terminal. Background technique [0002] A web page contains many web elements, such as pictures, text, and video. At present, there are two execution methods for the rendering work of browsers such as Chrome, the built-in browser of android, and third-party browsers (such as UC browser), one is completed in the main thread, and the other is completed in the rendering thread. Both methods perform similarly when rendering a web page. During the page rendering process, if it is found that the picture to be rendered has not been decoded, the picture needs to be decoded first, and then the picture is rendered after the decoding is completed, and then the next webpage element can be processed. [0003] Image decoding is a time-consuming task during web page rendering. Especially for web pages with multiple i...

AI Technical Summary

Problems solved by technology

If the webpage image is too large or there are many webpage images, the rendering speed of the webpage will be slow and the rendering efficiency of the webpage will be low.

When the main thread or rendering thread renders large images or multi-image webpages, because the main thread or rendering thread is decoding images and cannot perform other tasks, the rendering efficiency of the main thread or rendering threads is low, or even blocked. Caton appears

[0004] At the same time, if the image is being decoded during the rendering thread or the main thread webpage rendering process, and the user performs screen operations, such as swiping the screen or clicking a web page control, etc., since the main thread or the rendering thread is decoding the image at this time, it cannot When performing other tasks, the browser also freezes

[0005] Therefore, in the existing method, when the rendering thread or the main thread of the browser is performing large image rendering or multi-image rendering of the webpage, it cannot perform other tasks due to the decoding of the image, which will cause the browser to appear slow in rendering speed and inefficient. Low, even blocking or freezing may cause users to swipe the screen
