When user uses the client application of terminal device to check photo or video, the effect seen is all photos of display or video (wherein a part is former figure+thumbnail, and a part is only thumbnail).First application judges whether the photo that user checks or the former figure of video are stored in this locality, and as former figure is stored in this locality, then directly show former figure, operation terminates; If former figure is not stored in this locality, then show thumbnail, obtain former figure from cloud storage server and be kept at local terminal device, replacing thumbnail display on the terminal device, for user with former figure.The local storage of scanning subsequently takies situation, and judge whether that exceeding this locality stores the maximal value allowed, as do not exceeded, applying and not processing, operation terminates; As exceeded maximal value, the retention value of application by calculating local all photos or video, then the retention value of more local all photos or video, delete retention from this locality and be worth minimum former figure, only retain thumbnail, scanning this locality stores and takies situation again, judges whether that exceeding this locality stores the maximal value allowed, until the photo of terminal device storage or video take local storage space in allowed band.
The generation of view data and cloud storage, by access cloud stores service, for user provides magnanimity space, are integrated in a system application by the present invention simultaneously; Design the memory scheduling scheme of intelligence in the application, user is wanted the view data (as photo, video) seen retains on the terminal device, and only take little space, allow user browse the view data of oneself needs whenever and wherever possible.
Principle of the present invention adopts computing machine " internal memory-hard disk " model.Hard-disk capacity is large, but read or write speed is slow, and memory size is little, but read or write speed is exceedingly fast.Based on this feature; the present invention is saved in hard disk view data all for user; only retain in internal memory a small amount of user often can view data; when the view data of user is in internal memory; directly take from internal memory; when user's view data used is not in internal memory, just read from hard disk.The present invention adopts the cloud of infinite space to be stored as the realization of " hard disk ", and the various terminal devices (as iPhone, iPad, millet mobile phone, all kinds of computer and other mobile platforms etc.) of user are as " internal memory ", and internet is as data channel.
User uses application of the present invention and equipment can obtain the storage space of magnanimity.First the view data (photo, video as shooting) that user generates can preserve on the terminal device, and when network is unobstructed, (as under WiFi environment) automatic synchronization is to cloud storage server.Then by certain algorithm, memory scheduling module judges whether user frequently uses view data, if judge that user does not frequently use this view data, then the former figure of this view data is removed from terminal device, only retain thumbnail, when really will use this view data Deng user, then from cloud storage server, former figure is got back to terminal device for user by network.Thumbnail is more much smaller than former figure, for iPhone5 mobile phone, the former figure of photo of shooting on average often opens the space of occupied terminal equipment 2MB (1MB=1024KB), and the thumbnail of generation is generally no more than 40KB, so just for terminal device saves the space of more than 98%.Find according to statistics, the usual limited amount of the photo that user often checks (within 100), that is, terminal device only need reserve little space (as 250MB), just can meet the normal user demand of user's comparison film.Therefore, photo occupied terminal device memory reduces greatly, and this local maximal value allowed that stores can be set to default value (as 250MB), also can be arranged voluntarily in the application by user.
Adopt the present invention program, solve the problem of the photo of shooting, the video occupied terminal device space, overcome the drawback of existing manual settling mode; Set up the system of a kind of terminal camera+cloud dish+memory scheduling, realizing takes pictures uploads to the function that high in the clouds stores automatically, is convenient to user and follows one's bent shooting image, and can check image by cross-platform many equipment.The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within the scope of protection of the invention.
