For the ease of understanding the embodiment of the present invention, first to the present embodiments relate to some contents illustrate.
Wherein, HDR (i.e. zzHDR) technology of zigzag is current newest HDR technologies, supports to expose from photosensitive unit end
To lift the dynamic range of shooting image.ZzHDR exposure includes long exposure and short exposure, and piece image is divided into difference
Two sub-pictures of exposure parameter, synthesized when obtaining final shooting image, then by two sub-picture, due to the two secondary figure
As being obtained by photosensitive unit simultaneously, therefore time difference, content of shooting can be avoided to have differences, obtain the preferable high dynamic of effect
Range image.But because zzHDR is that piece image is divided into two parts, a part carries out growing exposure, and another part carries out short exposure
Light, therefore this two-part composograph can have loss in resolution ratio, also relatively be difficult to ensure that card closes even if optimal composition algorithm
Into image co-registration to former resolution ratio, i.e., there is loss in the high dynamic range images obtained by zzHDR in definition.
In addition, according to zzHDR principles, only in exposure parameter phase corresponding to exposure parameter corresponding to long exposure and short exposure
With in the case of, i.e., it is conventional shoot (only a kind of exposure parameter of a two field picture) in the case of, the definition of final shooting image is just not
There can be loss.
The present embodiments relate to main camera and secondary camera be only used for distinguish dual camera, not to camera carry out
Concrete restriction, the difference of major-minor camera can be carried out in actual application according to actual conditions.Specifically, the embodiment of the present invention
In the assembled scheme of dual camera can be as shown in table 1 below, and can be selected according to actual conditions.
Table 1
Wherein, RGB/Mono represents the different type of photosensitive unit, and RGB is color sensitive unit, and Mono is that black and white is photosensitive
Unit；Greatly/small size for representing photosensitive unit, wherein the photosensitive unit of identical size may be selected in main camera and secondary camera,
Also various sizes of photosensitive unit may be selected；Nomral/zzHDR represents that camera is the function that photosensitive unit is supported, wherein propping up
The photosensitive unit for holding zzHDR functions all supports conventional shooting, and zzHDR mainly contributes in dynamic range, therefore the present invention is real
At least one camera applied in the dual camera of example supports zzHDR functions.
It is shown in Figure 1, the embodiments of the invention provide a kind of image capturing method, applied to including main camera and pair
The mobile terminal of camera, wherein, at least one camera in main camera and secondary camera supports zzHDR functions, the figure
As image pickup method comprises the following steps：
Step 101：Receive shooting instruction.
Wherein, shooting instruction is that user confirms to input to mobile terminal when taking pictures, and can take pictures button etc. for click.Defeated
Before entering shooting instruction, user can carry out preview to shooting image, and preview data selects main camera or secondary camera to adopt
The view data collected.Original of the view data that a camera in selection dual camera collects as preview data
Because：Preview data only plays a part of reference, according to dual camera composograph data as preview data, due to closing
The resources such as processor, internal memory can be taken into view data, therefore previews can be caused to take excessive terminal resource, are influenceed follow-up
Take pictures process.After shooting instruction is received, main camera and secondary camera can shooting images.
Step 102：Whether the automatic exposure for detecting main camera and secondary camera is in synchronous regime.
Wherein, because the view data that the embodiment of the present invention will be shot to main camera and secondary camera synthesizes, because
Existence time difference and bat between this view data shot in order to avoid main camera and the view data of secondary camera shooting
Content deltas etc. is taken the photograph, avoids composograph from deforming, before the view data of main camera and the shooting of secondary camera is obtained,
Whether the automatic exposure that can detect main camera and secondary camera is in synchronous regime, and is detecting main camera and secondary shooting
The automatic exposure of head is in synchronous regime, obtains the view data of main camera and the shooting of secondary camera respectively.
Step 103：If detecting, the automatic exposure of main camera and secondary camera is in synchronous regime, obtains master respectively
First view data of camera shooting and the second view data of secondary camera shooting.
Wherein, main camera and secondary camera can shoot to obtain HDR in shooting image with a camera
Image, another camera shoot to obtain picture rich in detail, can also two cameras photograph can synthesize HDR respectively
The picture rich in detail of image.Specifically, when main camera and secondary camera work simultaneously, at least one camera utilizes zzHDR
Function.
It should be noted that the view data obtained in this step can be raw forms or YUV domains, and follow-up
Image synthesizing procedure can be completed in any one domain.When obtaining the view data of major-minor camera shooting, major-minor camera
The view data of shooting can be respectively enterd after different links carries out image real time transfer and is acquired again.
Step 104：First view data and the second view data are synthesized, obtain composograph.
Wherein, obtain the first view data of main camera shooting and the shooting of secondary camera the second view data it
Afterwards, mobile terminal can synthesize to the first view data and the second view data, obtain composograph.Calculated as synthesis
Method, existing image composition algorithm can be used.If not high to requirement of real time, the process of composograph can be in image file or figure
As being completed in data processing ISP flows.In addition, the process of composograph can also be carried out before JPG codings, to weaken user
Perception to the time required for synthesis.
Further, after composograph is obtained, mobile terminal can carry out conventional encoding and decoding to composograph and handle
And storage, subsequently to check use.
The image capturing method of the embodiment of the present invention, because mobile terminal includes main camera and secondary camera, main shooting
At least one camera in head and secondary camera supports zzHDR functions, therefore by receiving shooting instruction, detects main camera
Whether the automatic exposure with secondary camera is in synchronous regime, and synchronous shape is in the automatic exposure of main camera and secondary camera
During state, the first view data of main camera shooting and the second view data of secondary camera shooting are obtained respectively, to the first figure
As data and the second view data are synthesized, composograph is obtained, can not only be by the final composite diagram of zzHDR functional promotions
The dynamic range of picture, avoid because the dynamic range effect of composograph caused by the factors such as time difference, hand shaking is poor, so as to
To the preferable high dynamic range images of dynamic range effect, additionally it is possible to by dual camera by the loss of the definition of composograph
It is reduced to minimum.
In the embodiment of the present invention, further, if detecting, the automatic exposure of main camera and secondary camera is not in together
Step state, in order to ensure the effect of composograph, then the automatic exposure of main camera and secondary camera can be first controlled to be in synchronous
State, then the first view data of main camera shooting and the second view data of secondary camera shooting are obtained respectively.Specifically,
After step 102, methods described also includes：
If detecting, the automatic exposure of main camera and secondary camera is not in synchronous regime, controls main camera and pair
The automatic exposure of camera is in synchronous regime.
Wherein, after the automatic exposure of the main camera of control and secondary camera is in synchronous regime, mobile terminal difference
Obtain the first view data of main camera shooting and the second view data of secondary camera shooting.
It should be noted that when controlling the automatic exposure of main camera and secondary camera to be in synchronous regime, can use
Software controls, and can also use hardware controls.Automatic exposure commissioning requirements of the software control to major-minor camera are higher, exposing
Debugging is synchronized on light strategy.Hardware controls can be the exposure parameter for setting major-minor camera simultaneously, so compared to soft
Part is controlled, and hardware controls easily realize that control is synchronous, and both time differences can be easily controlled stable inside certain limit.
So, obtain main camera and secondary camera shooting view data before, it is ensured that major-minor camera it is automatic
Exposure is in synchronous regime, can avoid depositing between the view data of main camera shooting and the view data of secondary camera shooting
In time difference and content of shooting difference etc., ensure composograph effect.
Shown in Figure 2 in the embodiment of the present invention, before step 101, methods described also comprises the following steps：
Step 201：Determine light-metering camera.
Wherein, main camera or secondary camera of the light-metering camera for support zzHDR functions.Taken the photograph as main camera and pair
, can as shown in Table 1 above as the assembled scheme of head, the embodiment of the present invention is limited not to this.
Step 202：Light-metering is carried out using light-metering camera, obtains photometry result.
Wherein, light-metering is mainly the brightness for the current frame image for calculating the collection of light-metering camera, and judges current frame image
Brightness whether reach preset target brightness., need to be according to preset rules, such as by exposure if being not reaching to preset target brightness
Parameter adjustment table or exposure parameter adjustment step etc., adjust the exposure parameter of light-metering camera, carry out the convergence of automatic exposure,
So that the brightness of the image of light-metering camera collection reaches preset target brightness.The preset target brightness is mobile terminal according to reality
Border situation is pre-set.
It is noted that for major-minor camera, in the case where dual camera works simultaneously, due to a support
ZzHDR functions, another supports conventional shooting, therefore can be with dual camera light-metering simultaneously, photometry result synthesis two in light-metering
The result of person considers.Generally in the case where time for exposure and yield value are more or less the same, two photometry results be relatively, can
There can be nuance, but mainly the photometry result of the camera to support zzHDR functions is defined.Under some special screnes, such as
The serious scene of backlight, due to the survey of the camera of the photometry result of camera supporting routinely to shoot with supporting zzHDR functions
The difference of light result is larger, and the photometry result for the camera for supporting routinely to shoot is closer to reality, therefore can combine actual field
The photometry result of the camera routinely shot is supported in scape selection.
Step 203：It is bright that if the brightness of the current frame image of photometry result instruction light-metering camera collection reaches goal-selling
Degree, then according to the current frame image, determine the first exposure parameter and the second exposure parameter.
Wherein, the first exposure parameter is exposure parameter corresponding to long exposure, and the second exposure parameter is to be exposed corresponding to short exposure
The brightness value that the ratio of optical parameter, the first exposure parameter and the second exposure parameter is equal in the current frame image is more than or equal to pre-
If the pixel count in the highlight regions of threshold value is less than the ratio of the pixel count in the low bright area of the predetermined threshold value with brightness value.
, can first will be current when determining the first exposure parameter and the second exposure parameter specifically, according to current frame image
Normal exposure parameter corresponding to two field picture is defined as first exposure parameter, is then exposed in conjunction with the first exposure parameter and second
The ratio of parameter, second exposure parameter is determined, or normal exposure parameter corresponding to current frame image is defined as this first
Second exposure parameter, then in conjunction with the first exposure parameter and the ratio of the second exposure parameter, determine first exposure parameter.By
Taken the photograph in traditional pair under HDR patterns, determine that long exposure parameter T1 and short exposure parameter T2 method is similar to AE-Bracket methods,
I.e. after T1 is calculated, T2=T1*m, m are a constant or the variable simply to float, therefore compared to existing method, the present invention
The flexibility of the exposure parameter of determination first of embodiment and the method for the second exposure parameter is higher, it is determined that exposure parameter it is more accurate
Really, final image synthetic effect is more preferable.
Step 204：According to the first exposure parameter and the second exposure parameter, the exposure of main camera and secondary camera is set respectively
Optical parameter.
Wherein, according to the first exposure parameter and the second exposure parameter, the exposure of main camera and secondary camera is set respectively
During optical parameter, in order to ensure that composograph is high dynamic range images and loss of sharpness is very small, main camera and secondary shooting
The exposure parameter of head at least needs to meet following condition：(the exposure of i.e. main camera in the exposure parameter of main camera and secondary camera
The exposure parameter of optical parameter and secondary camera is combined) the first exposure parameter and the second exposure parameter are comprised at least, and master takes the photograph
As at least one camera in head and secondary camera only sets a kind of exposure parameter.It should be noted that main camera and pair are taken the photograph
As the exposure parameter of head comprises at least time for exposure and yield value.
Specifically, when main camera is light-metering camera, step 204 may include：
The exposure parameter of the main camera is arranged to first exposure parameter and second exposure by mobile terminal
Parameter, while the exposure parameter of the secondary camera is arranged to first exposure parameter, second exposure parameter or institute
State the 3rd exposure parameter corresponding to the current frame image of secondary camera collection；Wherein, the 3rd exposure parameter is by secondary camera root
It is calculated according to itself light-metering process, can is that the current frame image (brightness reaches preset target brightness) of secondary camera collection is corresponding
Normal exposure parameter.
So, the first exposure parameter and the second exposure parameter are arranged to the camera of a support zzHDR function simultaneously,
So lifting the image synthesizing section of dynamic range can be carried out at the photosensitive unit end of the camera or raw domains, the camera
It is high dynamic range images to shoot obtained image, and another camera is due to only setting a kind of exposure parameter, therefore shooting
Obtained image is picture rich in detail.So the composograph that thus dual camera obtains is high dynamic range images and definition
Loss is very small.
Further, existing double HDR image composition algorithms of taking the photograph often utilize Feature Points Matching, but remove and utilize Feature Points Matching
Outside, also need the brightness to each pixel to select to judge, that is, determine how pixel after calculating synthesis in two images
Brightness, with reach improve dynamic range effect.But due in the embodiment of the present invention, by by the first exposure parameter and second
Exposure parameter is arranged at the camera of a support zzHDR function simultaneously, and the camera can shoot obtained HDR figure
Picture, therefore the image synthesizing procedure in the embodiment of the present invention can only carry out Feature Points Matching, when being synthesized so as to save image
Between.In addition, the image synthesizing procedure in the embodiment of the present invention is also conceivable to sharpening etc., synthetic effect is lifted.
Specifically, in the embodiment of the present invention, step 104 may include：
By Feature Points Matching, described first image data and second view data are subjected to image synthesis, obtained
The composograph.
So, image synthesizing procedure is realized by Feature Points Matching, image generated time can be saved.
Or the exposure parameter of the main camera is arranged to first exposure parameter by mobile terminal, while by institute
The exposure parameter for stating secondary camera is second exposure parameter.
Or the exposure parameter of the main camera is arranged to second exposure parameter by mobile terminal, while by institute

So, the first exposure parameter and the second exposure parameter are respectively arranged at main camera and secondary camera, due to
One exposure parameter and the second exposure parameter correspond respectively to long exposure and short exposure, and are respectively in major-minor camera, therefore
The dynamic range effect of final composograph is preferably and loss of sharpness is very small, and compared to by the first exposure parameter and second
Exposure parameter is arranged at main camera or secondary camera simultaneously, can save the image co-registration process of camera under zzHDR patterns, letter
Change terminal operation.
Corresponding, when secondary camera is light-metering camera, step 204 may include：
The exposure parameter of the secondary camera is arranged to first exposure parameter and second exposure by mobile terminal
Parameter, while the exposure parameter of the main camera is arranged to first exposure parameter, second exposure parameter or institute
State the 4th exposure parameter corresponding to the current frame image of main camera collection；Wherein, the 4th exposure parameter is by main camera root
It is calculated according to itself light-metering process, can is that the current frame image (brightness reaches preset target brightness) of main camera collection is corresponding
Normal exposure parameter；
Or the exposure parameter of the main camera is arranged to first exposure parameter by mobile terminal, while by institute
