Abstract
The invention provides a photo saving method based on an intelligent terminal. The photo saving method comprises the following steps: S11, acquiring a photo; S12, presetting a callback function, and acquiring preview frame data of the photo; S13, processing the preview frame data; S14, generating a thumbnail of the corresponding photo based on the preview frame data; and S15, saving the photo. By adopting the above technical scheme, the generation time of the thumbnail can be reduced, and the use experience of a user can be improved.
Description
Technical field
The present invention relates to smart machine control field, more particularly to a kind of photo store method based on intelligent terminal.
Background technology
Under the environment that intelligent terminal market makes rapid progress, the camera function of intelligent terminal increasingly enriches on market, uses
Family increases for the use dependency degree of intelligent terminal's photo function, corresponding to require also increasingly to increase therewith.For the ease of user
Photo needed for positioning is quickly sought in a large amount of photo files for preserving, corresponding thumbnail can be generated to the photo for preserving, according to
Thumbnail is found.However, current breviary map generalization can expend some times after picture file preservation.With intelligent end
The photograph pixel more and more higher at end, the time of required generation thumbnail also lengthens therewith.
Therefore, in order to reduce the breviary map generalization time, improve user experience, need one kind to quickly generate thumbnail
Method.
The content of the invention
In order to overcome above-mentioned technological deficiency, it is an object of the invention to provide a kind of photo preservation side based on intelligent terminal
Method, can quickly generate thumbnail, give user more preferable Consumer's Experience.
The invention discloses a kind of photo store method based on intelligent terminal, comprises the following steps：
S11：Obtain photo；
S12：Default call back function, obtains the preview frame data of the photo；
S13：Process preview frame data；
S14:Based on the preview frame data, the thumbnail of the correspondence photo is generated；
S15：Preserve the photo.
Preferably, in step S12, described call back function includes auto-focusing preview call back function.
Preferably, in step S12, described preview frame data generate when being and obtaining photo in step S11 for preview
Frame data.
Preferably, the process preview frame data described in step S13, comprise the following steps：
S21：The byte data of preview frame is preserved by buffer；
S22：Obtain the resolution of thumbnail；
S23：The yuv data of thumbnail are converted into into jpg data；
S24：The jpg data are converted into into bitmap file.
Preferably, the resolution described in step S22 includes display width and shows height.
Preferably, the animation that the thumbnail of the generation correspondence photo described in step S14 is generated comprising thumbnail.
Preferably, the preservation photo described in step S15, including by application program generate thumbnail, and with institute
State photo association.
Preferably, described application program includes Thumb.Java.
Compared with prior art, it is of the invention it is a technical advantage that：
1. the thumbnail of photo photo preservation before, by preview frame data genaration；
2. photo generate thumbnail will not with photo become large-sized or uprising for pixel and increase；
3. in browsing pictures, thumbnail can quickly be presented user.
Description of the drawings
Fig. 1 is the schematic flow sheet for meeting photo store method in the embodiment of the present invention.
Specific embodiment
Advantages of the present invention is expanded on further below in conjunction with accompanying drawing and specific embodiment.
Refering to Fig. 1, to meet the embodiment of the present invention in intelligent terminal's photo store method schematic flow sheet.In the enforcement
It is the method for intelligent terminal's photo preservation in example.Specifically, comprise the following steps：
S11：Photo is obtained by shooting the form of photo.For example, the photograph that photographic head can be activated in intelligent terminal is started
Using the photo of acquisition correspondence current shooting picture after touch or click photographing button；
S12：Default call back function, obtains the preview frame data of the photo.While photo is shot, photographic head will be received
The control of default call back function in intelligent terminal, records and shoots the image frame of photo moment, and is stored as preview frame data.
It is understood that preview frame data can with shoot practical photograph it is identical or different, if obtain preview frame when and shooting
When there is gap between photo, preview frame and photo will be with differences.When preview frame is only follow-up pre- to user offer photo
The effect look at, convenient use person can quickly understand the difference between photo and photo, therefore, the difference between preview frame and photo will not
Affect the effect of preview frame or thumbnail in intelligent terminal.
The call back function that above-mentioned steps are used, can be auto-focusing preview call back function, remember after the completion of focusing
The frame data of record picture, use as preview frame.
S13：Process preview frame data.Specifically, include in the step：
-S21：The byte data of preview frame is preserved by default buffer in intelligent terminal；
-S22：After obtaining the byte data of preview frame, the resolution of thumbnail is analyzed.Due to the resolution of thumbnail it is excessive
Its preview effect will be affected, therefore, the threshold value of a resolution can be set in buffer, more than the threshold value, will delete again
Obtain preview frame；
-S23：The yuv data of preview frame in thumbnail are converted into into jpg data, to reduce the internal memory shared by thumbnail
Space size；
-S24：Finally, the jpg data are converted into into bitmap file, further the resolution of reduction preview frame, there is provided beat
Open speed during thumbnail.
It is understood that resolution mentioned above, it may include the display width and display height of preview frame, Liang Zhejie
Conjunction forms resolution.
S14:Based on the preview frame data, the thumbnail of the correspondence photo is generated, the thumbnail can be static
Photo or the animation generated by thumbnail.
S15：When preserving the photo, will be generated based on the application program such as Thumb.Java installed in intelligent terminal, and
Associate with photo, when user is when the picture library application in intelligent terminal is opened, the breviary that preview frame is formed will be directly displayed
Figure, due to through above-mentioned configuration, the acquisition of thumbnail and beats speed and will be greatly improved, therefore, even with person
Slide in the application, can immediately show the corresponding thumbnail of picture, convenient use person quickly finds desired picture or photo.
It should be noted that embodiments of the invention have a preferably implementation, and not any type of is made to the present invention
Limit, any one skilled in the art changes or be modified to the effective of equivalent possibly also with the technology contents of the disclosure above
Embodiment, as long as without departing from the content of technical solution of the present invention, being made to above example according to the technical spirit of the present invention
Any modification or equivalent variations and modification, still fall within the range of technical solution of the present invention.
