Method and device for image caching

Abstract

Embodiments of the present invention provide a picture caching method and apparatus. The method comprises: when it is detected that a user browses a current picture, determining whether there is a current picture in the cache; and when there is no current picture in the cache, obtaining the used space of the cache and determining whether the used cache space is greater than a preset threshold; ifso, obtaining browsing information of each picture in the cache, determining a to-be-deleted picture according to the browsing information, the preset threshold and the used cache space, and deletingthe to-be-deleted picture from the cache, and storing the current in the cache. Thus, according to the method and apparatus provided by the embodiments of the present invention, when the used cache space is greater than the preset threshold, the deleted picture can be determined according to the browsing information of the picture, the to-be-deleted picture can be determined with the reference tothe browsing behavior of the user, and pictures interested by the user can be retained in the limited cache space, so that re-downloading of the picture is avoided, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and device for caching pictures. Background technique [0002] With the popularization of smart mobile terminals and Apps (Applications), users can browse pictures through Apps, and in order to save the network traffic and download time of Apps to obtain pictures, usually cache space is allocated for Apps to store images passed through the Apps. Browse historical images. [0003] Due to the limited memory space of the smart mobile terminal, it is impossible to allocate more cache space for the App, so the pictures cached by the App are limited. When the cache space is insufficient, some cached pictures must be deleted to make room for the cache space to store new pictures. The existing picture cache replacement algorithm judges whether the picture should be replaced according to the time and number of times the picture is accessed, which can ensure that a fixed ...

Problems solved by technology

The existing picture cache replacement algorithm judges whether the picture should be replaced according to the time and frequency of the picture being accessed, which can ensure that a fixed size of storage space is occupied. When the user needs to browse the picture, it needs to be downloaded again, wasting network traffic and Download time, degrading user experience
