As shown in figure 1, being the flow chart of image pickup method in embodiments of the invention, the image pickup method comprises the following steps：
Step 101, the first view data and the second view data corresponding to every frame preview image of camera collection are obtained.
In this step, specifically, when user starts camera progress image preview, mobile terminal can obtain shooting
First view data and the second view data corresponding to every frame preview image of head collection.Wherein, the first view data and second
EV corresponding to view data is different.Certainly, in order to ensure more EV, the first view data can be got in preview image
Be long exposure image data or short exposure image data one of in the second view data, and per in frame preview image

During view data, the view data with multiple different EV can be got, so that in basis with multiple different EV
View data, when choosing the N number of target EV for meeting HDR image synthesis demand, the radix for choosing target EV is expanded, and then
Improve the target EV chosen accuracy.
Step 102, if receiving photographing instruction, the first view data and the second figure according to corresponding to per frame preview image
As data, N number of target light exposure value EV that HDR image synthesizes demand is determined for compliance with.
In this step, specifically, N value can be the positive integer more than 1.
In addition, in the first view data and the second view data according to corresponding to per frame preview image, HDR figures are determined for compliance with
As synthesis demand N number of target EV when, can from the first view data and the second view data corresponding to every frame preview image,
Selection meets N number of destination image data of default HDR image synthetic parameters；Then obtain each in N number of destination image data
Target EV corresponding to destination image data；Wherein, N number of destination image data includes normal exposure view data, long exposure image
Data and short exposure image data.
So, because every frame preview image is corresponding with the first view data and the second view data with different EV,
Therefore in the first view data and the second view data according to corresponding to per frame preview image, when determining N number of target EV, Neng Gougen
According to multiple the first view data with different EV and multiple the second view data with different EV, N number of target EV is determined, and
It is not that target EV can only be calculated according to the ratio of the clear zone in single-frame images and dark space, expands the selection for determining N number of target EV

During reason, the photo for meeting user's request can be obtained.
For example, it is assumed that N value is 5, and determine successively in sequence 5 target EV be+3ev ,+1ev, 0ev, -2ev, -
3ev, and+3ev and+1ev are respectively EV corresponding to long exposure image data, 0ev is EV corresponding to normal exposure view data ,-
2ev and -3ev be EV corresponding to short exposure image data, can now control camera respectively basis+3ev ,+1ev, 0ev, -
2ev, -3ev perform shooting operation, so as to obtain 5 images corresponding with being somebody's turn to do+3ev ,+1ev, 0ev, -2ev, -3ev, now,
Due to obtained 5 target EV accuracy, so that mobile terminal is to 5 images when carrying out image co-registration processing,
It can improve and carry out the effect of the image after HDR algorithm synthesis according to 5 target EV, and then can obtain meeting user's request
Image.
The present embodiment has different EV the first view data and the second figure by first obtaining corresponding to every frame preview image
As data, then the first view data and the second view data according to corresponding to per frame preview image, are determined for compliance with HDR image conjunction
Into N number of target EV of demand, and according to N number of target EV, shooting operation is performed so that mobile terminal, which can be got, multiple to be had
Different EV view data, so that mobile terminal can be selected and meet according to multiple view data with different EV
HDR image synthesizes N number of target EV of demand, N number of target EV selection radix is expanded, so as to improve the N number of mesh got
EV accuracy is marked, and then improves and the obtained effect of image is shot according to N number of target EV, solves and is clapping in the prior art
According to when, because the dynamic EV that detects is inaccurate, the effect of the image of caused HDR algorithms synthesis can not comply fully with user
It is required that the problem of.
Further, the first view data and the second picture number corresponding to every frame preview image of camera collection are being obtained
According to when, camera first figure according to corresponding to every frame preview image that default zzHDR exposure mode gathers can be obtained
As data and the second view data.
Because zzHDR can be used in live preview HDR image, to obtain EV, therefore diagonal data are detected by zigzag
ZzHDR can be in a frame preview image, while exports two view data with different EV, is enable to by taking the photograph
As head is according to default zzHDR exposure mode, gather per the first view data and the second picture number corresponding to frame preview image
According to.Of course, it is possible to correspond to different EV when different frame is set by zzHDR.
Specifically, default zzHDR exposure mode includes the first default exposure mode and the second default exposure mode.Under
Face is directed under the first default exposure mode and the second default exposure mode respectively, obtains every frame preview image of camera collection
The situation of corresponding first view data and the second view data is introduced.
First, camera is being obtained the according to corresponding to every frame preview image that default zzHDR exposure mode gathers
When one view data and the second view data, when zzHDR exposure mode presets exposure mode for first, obtain camera and adopt
First long exposure image data and the second normal exposure view data corresponding to each odd-numbered frame preview image of collection；Obtain shooting
First short exposure image data and the second normal exposure view data corresponding to each even frame preview image of head collection；Its
In, the first view data includes the first long exposure image data and the first short exposure image data, and the second view data includes institute
State the second normal exposure view data；EV corresponding to each first long exposure image data is different, each first short exposure figure
EV is different as corresponding to data.
Specifically, now the first default exposure mode refers to that each odd-numbered frame preview image exports the first long exposure image
Data and the second normal exposure view data, each even frame preview image export the first short exposure image data and second normal
Exposure image data, wherein, EV corresponding to each first long exposure image data is different, each first short exposure image data
Corresponding EV is different.
In such manner, it is possible to ensure that multiple long exposure image datas with different EV can be got in preview and with more
Individual different EV short exposure image data, is enable to expand target EV selection radix, and then can improve and select
The target EV arrived accuracy.
For example, as shown in following table 1.1 and table 1.2.Wherein, table 1.1 is expressed as each pixel in the preview image of odd-numbered frame
The corresponding view data of point, table 1.2 are expressed as the view data corresponding to each pixel in the preview image of even frame.Its
In, in table 1.1 and 1.2, long quick-fried expression exposure mode is long exposure mode, and now view data is long exposure image data；
Short quick-fried expression exposure mode is short exposure pattern, and now view data is short exposure image data；Normal expose represents exposure mode
For normal exposure pattern, now view data is normal exposure view data.
As can be seen that the first view data and the second view data point that the preview image of odd-numbered frame includes from table 1.1
Wei not long exposure image data and normal exposure view data；As can be seen that what the preview image of even frame included from table 1.2
First view data and the second view data are respectively short exposure image data and normal exposure view data.
So, the first default exposure mode is set by this kind of mode so that, can in the preview interface of mobile terminal
While the user is watched preview image by normal exposure view data, multiple long exposures with different EV can be got
Light image data and multiple short exposure image datas with different EV, so for target EV selection determine provide it is larger
Radix is selected, and then improves the target EV chosen accuracy.

In addition, specifically, it can be obtained as can be seen that when getting N frame preview images from the first default exposure mode
Get the N+1 view data with different EV.
For example, when N value is 6, i.e., when getting 6 frame preview image, due to each first long exposure image number
Different according to corresponding EV, EV corresponding to each first short exposure image data is different, and each odd-numbered frame preview image pair
Should there are the first long exposure image data and the second normal exposure view data, each even frame preview image is corresponding with the first short exposure
Light image data and the second normal exposure view data, therefore 6 frame preview images can get 3 first with different EV
Long exposure image data, and get 3 there are different EV the first short exposure image datas, and get one it is second normal
Exposure image data.Seven view data are now got altogether.
This is illustrated below.
Assuming that EV corresponding to the first long exposure image data during the first frame preview image is+1ev, the second frame preview image
When the first short exposure image data corresponding to EV be -1ev, the first long exposure image data during the 3rd frame preview image is corresponding
EV be+2ev, EV corresponding to the first short exposure image data during the 4th frame preview image is -2ev, the 5th frame preview image
When the first long exposure image data corresponding to EV be+3ev, the first short exposure image data during the 6th frame preview image is corresponding
EV be -3ev, EV corresponding to the second normal exposure view data during each frame preview image is 0ev, then can get with
Seven view data corresponding to upper seven EV.Then, after seven view data of the above are got, if HDR image synthesis needs
The target EV asked number is five, then can be selected more than in seven view data and meet default HDR image synthesis
Five destination image datas of parameter, and detect and obtain mesh corresponding to each destination image data in five destination image datas
Mark EV.For example, when it is respectively+3ev ,+1ev, 0ev, -2ev, -3ev that detection, which obtains five target EV, can be five according to this
Target EV determination order, control camera perform shooting operation according to five target EV respectively, obtained and five target EV phases
Corresponding five images.Now because the radix in the selection source of five destination image datas is larger, improve and determine what is obtained
Five target EV accuracy, and then improve the display effect of the image after HDR synthesis.
Second, camera is being obtained the according to corresponding to every frame preview image that default zzHDR exposure mode gathers
When one view data and the second view data, when zzHDR exposure mode presets exposure mode for second, obtain camera and adopt
First long exposure image data and the second normal exposure view data corresponding to each first odd-numbered frame preview image of collection；Obtain
First long exposure image data and the second short exposure image data corresponding to each even frame preview image of camera collection；Obtain
Take the corresponding first short exposed images number of each second odd-numbered frame preview image adjacent with each first odd-numbered frame preview image
According to the second normal exposure view data；Wherein, the first view data includes the first long exposure image data and the first short exposure
View data, the second view data include the second normal exposure view data and the second short exposure image data；Each first length
EV is differed corresponding to exposure image data, and EV corresponding to each first short exposure image data is differed, and each
EV corresponding to two short exposure image datas is differed.
Specifically, now the second default exposure mode refers to, each the first length of first odd-numbered frame preview image output exposure
View data and the second normal exposure view data, each even frame preview image export the first long exposure image data and second
Short exposure image data, each second odd-numbered frame preview image adjacent with each first odd-numbered frame preview image output first are short
Exposure image data and the second normal exposure view data；Wherein, the not phases of EV corresponding to each first long exposure image data
Together, EV corresponding to each first short exposure image data is differed, and EV corresponding to each second short exposure image data is equal
Differ.
So, the second default exposure mode is passed through so that for the first default exposure mode, enable to pass through
The preview image of less frame gets the more long exposure image data with different EV and the short exposure figure with different EV
As data, so that while can expand target EV selection radix, the efficiency for obtaining target EV is improved.
For example, as shown in following table 2.1 to table 2.4.Wherein, table 2.1 is expressed as in the preview image of the first odd-numbered frame each
View data corresponding to pixel, table 2.2 represent each pixel in the even frame preview image adjacent with the first odd-numbered frame
Corresponding view data, table 2.3 represent in the second odd-numbered frame preview image adjacent with the first odd-numbered frame each pixel institute
Corresponding view data, table 2.4, which represents in the even frame preview image adjacent with the second odd-numbered frame that each pixel is corresponding, schemes
As data.Wherein, in table 2.1 into table 2.4, long quick-fried expression exposure mode is long exposure mode, and now view data exposes to be long
Light image data；Short quick-fried expression exposure mode is short exposure pattern, and now view data is short exposure image data；It is normal to expose table
It is normal exposure pattern to show exposure mode, and now view data is normal exposure view data.
As can be seen that the first view data and the second view data that the first odd-numbered frame preview image includes from table 2.1
Respectively long exposure image data and normal exposure view data；As can be seen that what even frame preview image included from table 2.2
First view data and the second view data are respectively short exposure image data and long exposure image data；Can be with from table 2.3
Find out, the first view data and the second view data that the second odd-numbered frame preview image includes be respectively short exposure image data and
Normal exposure view data；The first view data and the second image that even frame preview image includes are can be seen that from table 2.4
Data are respectively short exposure image data and long exposure image data.
So, the second default exposure mode is set by this kind of mode so that for the first default exposure mode,
More long exposure image data and short exposure image data can be got by the preview image of less frame, improves acquisition
To the efficiency of the view data with different EV, and then improve the efficiency for getting target EV.It is in addition, second default by this
Exposure mode, determine to provide larger selection radix for target EV selection, and then improve the target EV chosen standard
True property.

In addition, specifically, it be can be seen that from the second default exposure mode when getting N frame preview images, if N is
Odd number, then it can get N+ (the N-1)/2+1 view data with different EV；If N is even number, N+N/2+ can be obtained
1 view data with different EV.
For example, when N value is 4, i.e., when getting 4 frame preview image, due to each first long exposure image number
Differed according to corresponding EV, EV corresponding to each first short exposure image data is differed, each second short exposed images
EV is differed corresponding to data, and each first odd-numbered frame preview image is being corresponding with the first long exposure image data and second just
Normal exposure image data, each even frame preview image are corresponding with the first long exposure image data and the second short exposed images number
According to each second odd-numbered frame preview image adjacent with each first odd-numbered frame preview image is corresponding with the first short exposed images number
According to the second normal exposure view data, therefore 4 frame preview images can get 3 have different EV the first long exposure diagrams
