The first driving current value of the motor of main camera is determined, drives main camera to be focused using the first driving current value.By
Relatively low in secondary resolution ratio of camera head, image processing speed is very fast, so as to accelerate speed of focusing, solves double in the prior art
The slow technical problem of camera focusing.
During the specific implementation of dual camera, different cameras can be selected to combine, as in dual camera
Main camera and secondary camera, so as to adapt to different user's requests.
, it is necessary to higher focusing speed in a kind of application scenarios, so as to which the main camera in dual camera is specially general
Logical camera, the secondary camera in dual camera is specially plain (PD, the dual pixel) camera of double image.Wherein, double PD shootings
The resolution ratio of head will be less than common camera, so as to focusing speed faster.
It should be noted that each pixel of double PD cameras is made up of two units, two units can be used as phase

Fruit.
In the selection of specific dual camera, there can also be a variety of possible implementations, in the present embodiment to this no longer
Repeat.
The schematic flow sheet for the first imaging method that Fig. 1 is provided by the embodiment of the present application.
As shown in figure 1, the imaging method comprises the following steps：
Step 101, the master image that main camera collects is obtained, and obtains the secondary figure that secondary camera collects
Picture.
In the present embodiment, under the scenes such as HDR, in the picture of finding a view of dual camera, brightness range span compared with
Greatly, easily occur in that a part of region is under-exposure, the situation of another part region overexposure, cause shooting effect bad.
In such a scenario, ambient brightness can be determined previously according to the mean flow rate of multiple light-metering points, from dual camera
The main camera of middle determination and secondary camera.
Specifically, in the case of due to being not higher than threshold luminance in ambient brightness, insufficient light, if using high-resolution
Camera when being taken pictures as main camera, then more noise occurs, so as to cause imaging effect bad.Therefore,
In the present embodiment, in insufficient light, the camera of ISO can be used as main camera, high-resolution camera
Taken pictures as secondary camera, reduce the noise in image, improve imaging effect.On the contrary, it is higher than threshold value in ambient brightness
In the case of brightness, i.e., in the case of bright and clear, because high-resolution resolution ratio of camera head is higher, imaging is also more clear
Clear, noise is less, therefore, in the present embodiment, can make high-resolution camera as main camera, high photosensitive camera
Taken pictures for secondary camera, so as to improve imaging effect.
It is determined that after main camera and secondary camera, bat of finding a view can be carried out using main camera and secondary camera simultaneously
Take the photograph, respectively obtain master image and width image.
Before being shot, preview can be carried out to image., can be only right as a kind of possible implementation
The picture of main camera collection carries out preview, when user sees satisfied preview screen, shoot button is clicked on, so as to control master
Camera and secondary camera carry out shooting of finding a view simultaneously.Or preview can be carried out to the picture that secondary camera gathers, work as user
When seeing satisfied preview screen, shoot button is clicked on, so as to control main camera and secondary camera while carry out shooting of finding a view,
This is not restricted.
Step 102, the exposure information obtained according to light-metering, the exposure adjustment region of master image and corresponding exposure are determined
Compensated information.
In the embodiment of the present invention, exposure information is the obtained multiple exposure values of matrix light-metering, can be according to exposure information, really
It is scheduled on the exposure value of multiple light-metering points that matrix is arranged in master image.
As a kind of possible implementation, master image can be divided into according to the picture continuity of finding a view of master image
Multiple units, for example, with reference to Fig. 2, Fig. 2 is the division schematic diagram of master image in the embodiment of the present invention.According to finding a view for master image
Picture continuity, master image can be divided into nine units, respectively unit A, B, C, D, E, F, G, H, I.
Then can according to contained by each unit light-metering point exposure value, the exposure value of determining unit, for example, can will
The exposure value of all light-metering points of the unit takes average, the exposure value using average as the unit, or, the unit can be calculated
It is all light-metering points and value, using with value as the unit exposure value, or, the list can be calculated according to other any particular algorithms
The exposure value of member, is not restricted to this.After the exposure value of determining unit, master image can be determined according to the exposure value of unit
Exposure adjustment region and corresponding exposure compensating information, wherein, exposure compensating information for example can be to need the exposure that compensate
Light value.
It is understood that when exposing suitable, the exposure value of each unit should be in default span, and this is default
Span can be that the plug-in of mobile terminal is pre-set, such as the default span of mark is [a, b].When unit
When exposure value is not in default span, it may be determined that the unit is exposure adjustment region.For example, when the exposure value of unit
Less than default span minimum value a when, show that the unit is under-exposure, when exposure compensating information to need the exposure value that compensates
When, now, exposure compensating information can be on the occasion of.And when the exposure value of unit is higher than the maximum b of default span, table
The bright unit overexposure, now, exposure compensating information can be negative value.
Step 103, according to master image and sub-picture, the depth information of master image is obtained.
Specifically, due to having a certain distance between major-minor camera, so as to result in the two cameras have regard
Difference, the image of different cameras shooting should be different.Master image is shot to obtain by main camera, width image be by
Secondary camera shoots what is obtained, therefore, should also have different between master image and sub-picture.It is former according to range of triangle
Reason, can be calculated in master image and sub-picture, the depth information of same target, that is, the main camera of the object distance and
The distance of plane where secondary camera.
For clear this process of explanation, principle of triangulation will briefly be introduced below.
And in actual scene, the depth that human eye differentiates scenery is mainly what is told by binocular vision.This is imaged with double
The principle of head resolution depth is the same.The depth information of image, main side are calculated in the present embodiment according to the second shooting image
Method is to rely on principle of triangulation, and Fig. 3 is the principle schematic of range of triangle.
Based in Fig. 3, in real space, imaging object, and two camera position O are depictedRAnd OT, with
And the focal plane of two cameras, the distance of plane is f where two cameras of focal plane distance, is respectively taken the photograph in focal plane position two
As head is imaged, so as to obtain two shooting images.
P and P ' is position of the same target in different shooting images respectively.Wherein, P points are apart from place shooting image
The distance of left border is XR, P ' points are X apart from the distance of the left border of place shooting imageT。ORAnd OTRespectively two are taken the photograph
As head, for the two cameras in same plane, distance is B.
Based on principle of triangulation, the distance between plane Z, has as follows where the object and two cameras in Fig. 3
Relation：
Based on this, can push awayWherein, d is position of the same target in different shooting images
The distance between put difference.Because B, f are definite value, therefore, the distance Z of object can be determined according to d.
Step 104, according to the depth information of master image, foreground area and the background area of master image are determined.
Specifically, be calculated after the depth information of master image, can according to the depth information of each object in master image,
It is prospect or background to determine the object.In general, depth information denoted object where the major-minor camera plane compared with
Closely, when depth value is smaller, it may be determined that the object is prospect, and otherwise, the object is background.And then can be according in master image
Each object, determine foreground area and the background area of master image.
Step 105, in foreground area and the intersection of exposure adjustment region, exposed according to corresponding to exposure adjustment region
Compensated information, adjustment is exposed to master image.
In the embodiment of the present invention, the exposure value due to exposing adjustment region is likely lower than the minimum value a of default span,
Or the maximum b higher than default span, therefore the number for exposing adjustment region can be multiple.Therefore, the present invention is real
Apply in example, when it is determined that master image exposure adjustment region after, can in foreground area, respectively determine with each exposure adjust
The intersection in region, then in the intersection of each exposure adjustment region, according to exposure corresponding to exposure adjustment region
Light compensated information, adjustment is exposed to master image.
As a kind of possible implementation, can according to corresponding to exposure adjustment region exposure compensating information, carry out bright
One or more of degree, contrast and color saturation are adjusted.
, can be with for example, when exposing the exposure value of intersection of adjustment region and being less than the minimum value a of default span
Brightness is carried out to the intersection and heightens processing, or carry out brightness simultaneously, contrast and color are satisfied and heighten processing.And when exposure
When the exposure value of the intersection of adjustment region is higher than the maximum b of default span, the intersection can be carried out bright
Degree turns down processing, or carry out brightness simultaneously, contrast and color are satisfied and turn down processing.
Step 106, carry out virtualization in background area, the master image after being adjusted to exposure and handle to obtain image.
In the embodiment of the present invention, in background area, the master image after being adjusted to exposure carries out virtualization processing, obtains image
Picture, in image, prospect is more prominent, and background is blurred, and shows the imaging effect of the prospect of focusing.In addition, this
In inventive embodiments, virtualization processing only is carried out to background area, imaging effect influenceed not so as to the exposure status of background area
Greatly, it is therefore not necessary to be exposed processing to background area, the treatment effeciency of mobile terminal is effectively lifted.
The imaging method of the present embodiment, the master image collected by obtaining main camera, and obtain secondary camera
After the sub-picture collected, the exposure information that is obtained according to light-metering, the exposure adjustment region and correspondingly of master image is determined
Exposure compensating information.And then according to master image and sub-picture, the depth information of master image is obtained, so as to finally according to master image
Depth information, determine foreground area and the background area of master image, pass through the coincidence in foreground area and exposure adjustment region
Part, according to exposure compensating information corresponding to exposure adjustment region, it is exposed adjustment to master image, and in background area, it is right
Master image after exposure adjustment carries out virtualization and handles to obtain image.In the present embodiment, by advance light-metering, master image is determined
Exposure adjustment region and corresponding exposure compensating information, so as to according to exposure adjustment region corresponding to exposure compensating believe
Breath, adjustment is exposed to master image, can effectively be avoided occurring overexposure region in image and be owed to expose region, lifting imaging
The exposure effect of image.Meanwhile the sub-picture of secondary camera shooting and main camera shooting master image are that sync pulse jamming obtains,
So as to which the master image after being adjusted according to corresponding sub-picture to exposure carries out follow-up virtualization processing, on the one hand improve imaging and shine
The imaging effect of piece, the accuracy of depth information is on the other hand improved, so that image processing effect is preferable.

3EV or so, if environment light source is partially dark, exposure value is larger；Conversely, environment is relatively bright, exposure value is smaller.
It should be noted that EV is a how many amount of reflection exposure, it is originally defined as：When sensitivity be ISO 100,
When aperture-coefficient is F1, the time for exposure is 1 second, light exposure is defined as 0, light exposure reduce one grade (aperture time reduce half or
One grade of person's stop down), EV values increase by 1.Exposure value, which often increases by 1, will change a gear exposure, that is, light exposure is halved, such as
Time for exposure or aperture area are halved.Bright environment or higher sensitivity should correspond to larger exposure value.
Step 202, according to exposure information, exposure parameter is determined.
In the embodiment of the present invention, exposure parameter includes shutter speed, F-number and/or sensitivity etc..
As a kind of possible implementation, the corresponding pass between different exposure informations and exposure parameter can be pre-established
