Electronic device, and image processing method and system of application

Abstract

The invention provides an electronic device, and an image processing method and system of an application. A first cache mapping table is established for key values according to resource sizes, partial bytes and postfix names of downloaded pictures, and the pictures are cached locally according to the first cache mapping table. When the pictures need to be downloaded subsequently, the matched pictures can be searched locally according to the postfix names, resource sizes and partial bytes of to-be-downloaded pictures; if there are matched pictures, the pictures are directly obtained; and if there is no matched picture, the pictures are downloaded from a control end. The pictures are prevented from being downloaded repeatedly, and the picture obtaining efficiency is high; matching is carried out for the key values according to the postfix names, resource sizes and partial bytes of the pictures, and the matching accuracy is improved; and the problem that in the prior art, the processing efficiency is reduced due to the fact that the matching is carried out for the key values only according to the picture names, the matching result is inaccurate, and the pictures need to be downloaded repeatedly is prevented.

Description

technical field [0001] The present invention relates to the field of picture processing and optimization, in particular to an electronic device, and a picture processing method and system applied thereto. Background technique [0002] With the rise and popularity of mobile smart devices, the emergence of Dlna technology based on the Upnp protocol enables the interconnection between devices, allowing our photos, videos, and music to be shared between mobile devices, thereby enabling unlimited digital media and content services It becomes possible to share and grow, for example, to project photos from mobile devices such as mobile phones and tablets to the large screen of a smart TV for display. However, as the camera pixels of the current mobile devices are getting higher and higher, the resource size of the captured pictures is getting larger and larger, so when projecting pictures and switching back and forth for picture display, it is necessary to load pictures. The inter...
