Stating photo acquisition methods includes:
Step 201, when terminal is in low electricity condition, frame data and the frame data for obtaining the terminal camera are corresponding
View-finder screenshot.
Exemplary, in order to meet the diversified demand of user, the higher camera of pixel usually can be all arranged in existing mobile phone,
Although the higher high definition photo of clarity can be shot, the experience of taking pictures of user is improved.But due to being clapped using high pixel
The data for needing to acquire when taking the photograph every photo are larger, therefore one photo of every shooting will expend more electricity.At terminal
It when low electricity condition, if user wants shooting photo, needs first to open the camera of mobile phone, then adjusts the shooting ginseng of camera
Number shoots photo using the acquisition parameters adjusted, this process used time is longer, may just adjust acquisition parameters in user
When, just as electricity exhausts and automatic shutdown, user will be unable to get the photo for wanting shooting mobile phone at this time, it is likely that can give
User causes the sorry of all one's life.Therefore frame data and the institute of the terminal camera can be obtained when terminal is in low electricity condition
The corresponding view-finder screenshot of frame data is stated, when the view-finder screenshot is that camera is found a view using current frame data, view-finder is current

Machine just enters low electricity condition, then can choose the biggish acquisition period, economize on resources, for example, the acquisition period of selection can be with
For 3s.
It is exemplary, when terminal is in low electricity condition, can not be saved although there is the photo of shooting, or can not clap in time
The risk of photo is taken the photograph, but if user considers for energy saving or memory space, it is also possible that terminal is in low electric shape
Acquisition when state, without frame data and view-finder screenshot.Such as.Protective switch of taking pictures can be set in terminal, when user needs
When terminal opens acquisition frame data and view-finder screenshot, the protective switch of taking pictures is opened, opens acquisition when user does not need terminal
When frame data and view-finder screenshot, the protective switch of taking pictures can be closed.When terminal is in low electricity condition, can detect first
Whether the protective switch of taking pictures is opened, if the protective switch unlatching of taking pictures, obtains the frame data and view-finder screenshot of camera,
In order to redraw photo；If the protective switch closing of taking pictures, does not need the frame data and view-finder screenshot that obtain camera.
Step 202, when the terminal re-powers, according to the frame data and the view-finder screenshot, described in acquisition
The corresponding photo of view-finder screenshot.
It is exemplary, when terminal again socket power or terminal are fully charged and when being switched on again, illustrate that terminal re-powers,
At this time if the frame number of terminal storage can be searched when user prepares the image obtained when wanting to reacquire terminal automatic shutdown
According to view-finder screenshot, the corresponding photo of view-finder screenshot, the frame number are then redrawn according to frame data and view-finder screenshot
According to including but not limited to pixel AWB data, exposed frame value of finding a view, the time for exposure, ISO etc. redraws view-finder by frame data
The corresponding photo of screenshot belongs to the prior art, and this will not be repeated here for the embodiment of the present invention.
It is illustrated so that terminal repeatedly obtains frame data and view-finder screenshot according to the acquisition period as an example, terminal can be successively
Terminal can be consulted and deposit when user needs to redraw photo by storing frame data and view-finder screenshot that each acquisition period obtains
All frame data and view-finder screenshot of storage, what then the selection of the view-finder screenshot according to shown in terminal was redrawn finds a view
Frame screenshot, after terminal determines view-finder screenshot selected by user and the view-finder screenshot corresponding frame data, can should
The corresponding frame data of view-finder screenshot redraw the view-finder screenshot, photo needed for getting user.Specifically, can be with
As shown in figure 4, when user needs to redraw photo, the storage interface that can be opened a terminal successively is shown on the storage interface
