The terminals such as brain.As it is shown in figure 1, the method flow process specifically includes:
101, the initial preview resolution during the screen resolution of terminal and terminal taking is obtained.
Wherein, initial preview resolution is identical with the resolution ratio of camera head of terminal.
In actual applications, the shooting process of user relates to three resolution parameters, specifically includes: resolution ratio of camera head,
Screen resolution and preview resolution.In order to obtain the picture of different quality, the photographic head of different resolution can be selected
Becoming the gatherer process of image, resolution ratio of camera head as corresponding in picture that size is 8M is 3264*2448, and size is the figure of 13M
The resolution ratio of camera head that sheet is corresponding is 4208*3120.The size of screen resolution is determined by the hardware configuration of screen, such as FHD (English
Literary composition: Full High Definition, Chinese: full HD) screen resolution that shields is that 1920*1080, HD are (English: High
Definition, Chinese: high definition) screen resolution that shields is 1280*720.And in order to ensure preview effect, generally use shooting
Head resolution is as preview resolution.
At present, owing to terminal realizing the software section of camera function, " preview " and " taking pictures " can be realized and separately process, i.e.
Preview, by one group of parameter, is taken pictures and is organized parameter with another, between parameter and the parameter of process of taking pictures use that previews uses mutually
Do not affect.Therefore, the change of preview resolution can't affect the quality of picture.
It should be noted that user can select different resolution ratio of camera heads according to self-demand, but work as taking the photograph of terminal
As head is fixed, then the maximum of resolution ratio of camera head is the full-scale resolution of photographic head.
102, determine that whether initial resolution is more than screen resolution.
If initial preview resolution is more than screen resolution, then perform step 103 and step 104；Otherwise, step is performed
105。
103, according to the ratio of initial preview resolution with the Vertical number of pixels of screen resolution, and initial preview resolution
Preview ratio is determined with the ratio of the Horizontal number of pixels of screen resolution.

Prime number, it is determined that initial preview resolution is more than screen resolution；Otherwise determine that initial preview resolution is less than or equal to screen
Resolution.It is compared in prior art preview resolution and resolution ratio of camera head are set to identical resolution, the present invention
On the basis of the too high power consumption of terminal caused is big because of preview resolution the problem of solution, only vertical when initial preview resolution
Pixel count is more than the Vertical number of pixels of screen resolution, and the Horizontal number of pixels of initial preview resolution is more than screen resolution
During Horizontal number of pixels, determine that initial preview resolution is more than screen resolution, thus avoid initial preview resolution adjustment not conform to
Reason, the impact on preview effect.
In order to ensure the preview effect after adjusting preview resolution, in an implementation of the embodiment of the present invention, will
The ratio of the Vertical number of pixels value less with the ratio of Horizontal number of pixels is as preview ratio.Therefore, in realization side as shown in Figure 1
On the basis of formula, it is also possible to be embodied as implementation as shown in Figure 3.Wherein, step 103 is according to initial preview resolution and screen
The ratio of Vertical number of pixels of curtain resolution, and the ratio of initial preview resolution and the Horizontal number of pixels of screen resolution determines pre-
Look at ratio, step 1031 can be implemented as to 1033:
1031, determine whether the ratio of Vertical number of pixels is more than the ratio of Horizontal number of pixels.
If the ratio of Vertical number of pixels is more than the ratio of Horizontal number of pixels, then perform step 1032；Otherwise, step is performed
1033。
In order to avoid the initial preview resolution after adjusting is less than screen resolution, thus affect preview effect, by level
Less in the ratio of pixel count and the ratio of Vertical number of pixels one, is defined as preview ratio.Such as, initial preview resolution is
3264*2448, screen resolution is 1920*1080, and the ratio 3264/1920 of Vertical number of pixels is less than the ratio of Horizontal number of pixels
2448/1080, the ratio of Vertical number of pixels is defined as preview ratio；Initial preview resolution is 3264*2448, screen resolution
For 1280*1024, the ratio 3264/1280 of Vertical number of pixels more than the ratio 2448/1024 of Horizontal number of pixels, by Horizontal number of pixels it
