Below the first information processing method in the application is described in detail, please refer to Fig. 1.
S1: the image acquisition units of described electronic equipment obtains the preview image of pickup area.
Specifically, in the embodiment of the present application, image acquisition units, before acquisition image, first can obtain the preview image of image, and is presented on the display unit of electronic equipment by preview image.After user watches preview image on the display unit, if preview image is not the image that user needs, user can adjust preview image, until obtain the image oneself needed by the health of mobile electronic device or movement oneself.Technical scheme for convenience of description in the application, suppose that user needs shooting people to stand in seabeach, the preview image finally obtained as shown in Figure 2.
After obtaining preview image, perform step S2.
S2: described preview image is divided into N number of region.
In order to obtain different imagery optical parameters, and by different multiple images of imagery optical gain of parameter, finally obtaining best composograph, after acquisition preview image, needing preview image to be divided into N number of region.Wherein, N is for being more than or equal to 2, and as 2, the concrete value of 3,8,4 etc., N does not do concrete restriction in this application.
Specifically, in the embodiment of the present application, be divided into N number of region for by preview image, have two kinds of methods, certainly, in specific implementation process, division methods is not limited to following two kinds.
The first:
Divide N number of region by first method, realize especially by following steps:
(1) N number of operation that the first operating body carries out for described preview image is obtained.
Specifically, in the embodiment of the present application, the first operating body can the hand of user, and can be pointer, can also be mouse, the application do concrete restriction yet.When the display unit of the electronic equipment in the application is for possessing touch controllable function, user can directly operate on preview image with finger or pointer; When the electronic equipment in the application can connect mouse, user can operate by mouse beacon on preview image.
(2) according to described N number of operation, described preview image is divided into described N number of region.
Obtain user for N number of operation of preview image after, for N number of operation of user, just preview image can be divided into N number of region.Specifically, illustrate with the example in above-mentioned preview image, when the display unit of the electronic equipment in the application is for possessing touch controllable function, suppose that user's finger or pointer operate in the mode of drawing a circle on preview image, its operation trace is as shown in dotted line in Fig. 2, Fig. 3, Fig. 4 and Fig. 5; When the electronic equipment in the application can connect mouse, suppose user's mouse beacon with the mode of drawing a circle operation on preview image, its operation trace is as shown in dotted line middle in Fig. 2, Fig. 3, Fig. 4 and Fig. 5.
In order to clearly illustrate, suppose that N number of operation is specially N number of touch control operation, and be 2 to illustrate with N.As shown in Figure 4, because people is when taking pictures in seabeach, the brightness of personage is very low, but background, namely the brightness of seabeach and sky is very high, and in order to obtain different IMAQ optical parametrics for figure and ground, the people in preview image will iris out by touch control operation by user, and background also irised out, the operation trace of two touch control operations as shown in phantom in figure 4.So, just according to user's two operation, preview image can be divided into 2 regions, namely with the closed area that the operation trace of two touch control operations surrounds.
The second:
Divide N number of region by first method, realize especially by following steps:
(1) M the operation that described first operating body carries out for described preview image is obtained.
Specifically, in the embodiment of the present application, M 0 is more than or equal to, and is less than the integer between N, and namely M can be 0,1, N etc., M concrete value, and the application does not limit.
Specifically, in the embodiment of the present application, the first operating body can the hand of user, and can be pointer, can also be mouse, the application do concrete restriction yet.When the display unit of the electronic equipment in the application is for possessing touch controllable function, user can directly operate on preview image with finger or pointer; When the electronic equipment in the application can connect mouse, user can operate by mouse beacon on preview image.
(2) according to described M operation, be M region by the Region dividing of described M operation correspondence.
Obtain user for M of preview image operation after, for M the operation of user, can be just M region by M the Region dividing operated corresponding in preview image.Specifically, illustrate with the example in above-mentioned preview image, when the display unit of the electronic equipment in the application is for possessing touch controllable function, suppose that user's finger or pointer operate in the mode of drawing a circle on preview image, its operation trace is as shown in dotted line in Fig. 2, Fig. 3, Fig. 4 and Fig. 5; When the electronic equipment in the application can connect mouse, suppose user's mouse beacon with the mode of drawing a circle operation on preview image, its operation trace is as shown in dotted line in Fig. 2, Fig. 3, Fig. 4 and Fig. 5.
In order to clearly illustrate, suppose that M operation is specially M touch control operation, and be 2 to illustrate with M.As shown in Figure 5, because people is when taking pictures in seabeach, the brightness of personage is very low, but background, namely the brightness of seabeach and sky is very high, and in order to obtain different IMAQ optical parametrics for figure and ground, the people in preview image will iris out by touch control operation by user, and the object liked by background partial user is also irised out, and the operation trace of two touch control operations as shown in broken lines.So, due to user two touch control operations for region be people's object area and coco region, so just according to user's two operation, preview image can be divided into 2 regions, namely with the closed area that the operation trace of two touch control operations surrounds.
(3) according to the monochrome information of described preview image, be N-M region by the Region dividing beyond a described M region.
After obtaining M region, for the region beyond M region, also need to be divided into N-M region.In the embodiment of the present application, be N-M region by the Region dividing beyond M region, mainly divide according to the monochrome information of preview image.
Specifically, in the embodiment of the present application, the method dividing N-M region has multiple, and as divided according to monochrome information or half-tone information division, belonging to certain the application, technical staff can select according to actual needs, and the application does not do concrete restriction.
Suppose to divide with monochrome information, suppose to select A point at random, centered by A point, the point being no more than threshold value with A point luminance difference is divided into same region.Such as, setting threshold is 10000 nits, the brightness of the A point chosen at random is 30000 nits, and so the point and A point that are no more than 10000 nits near A point with the difference of A point brightness are divided in the same area, the point being 20000-40000 nit by brightness near A point is divided into the same area.
In order to clearly illustrate, suppose that M operation is specially M touch control operation, and to be 2, N be 4 illustrates with M.As shown in Figure 6, beyond the region surrounded compared with thick dashed line, because the brightness of the corresponding near zone of the sun is the highest, be so a region by solar neighborhood Region dividing, as in figure compared with the region that fine dotted line and image border surround, and remaining region is classified as a region.
Suppose that M operation is specially M touch control operation, and to be 2, N be 3 illustrates with M.As shown in Figure 5, beyond the region surrounded compared with thick dashed line, because N is 3, so just direct is a region by remaining whole Region dividing.
Especially, when M is 0, electronic equipment will divide N number of region automatically.
After division obtains N number of region, perform step S3.
S3: determine N number of IMAQ optical parametric that described N number of region is corresponding.
After obtaining N number of region, next determine N number of IMAQ optical parametric according to the information in N number of region exactly.In the embodiment of the present application, in N number of region, arbitrary region is corresponding with an IMAQ optical parametric in N number of IMAQ optical parametric, that is, each IMAQ optical parametric in N number of IMAQ optical parametric has a unique corresponding region, also there is a unique corresponding IMAQ optical parametric in each region in N number of region, and N number of image and N number of IMAQ optical parametric are one to one.
In the embodiment of the present application, step S3 is implemented as:
Get i successively from 1 to N,
Adjustment present image gathers optical parametric, when described present image gather optical parametric meet corresponding with the i-th region i-th pre-conditioned time, determining that described present image gathers optical parametric is the i-th IMAQ optical parametric corresponding to described i region, and i is the integer of 1 to N;
When i is N, obtain described N number of IMAQ optical parametric.
In order to said method is described, for the 1st IMAQ optical parametric in the 1st region.First the average brightness of each zonule having electronic equipment to divide is obtained by central area light-metering or central point light-metering, for the 1st region, adjustment present image gathers optical parametric, as exposure parameter, can be that user manually adjusts, also can be that electronic equipment adjusts automatically, meet corresponding with the 1st region the 1st pre-conditioned until present image gathers optical parametric, when meeting a certain functional relation as namely made the average brightness of each zonule, determining that described present image gathers optical parametric is the 1st IMAQ optical parametric corresponding to the 1st region.Visible, when gathering optical parametric for the 1st region adjustment present image, whether can make image 1st region in obtain optimum efficiency, do not pay close attention to other regional effect if only paying close attention to present image collection optical parametric, thus can ensure that the image in the 1st region is the best.
Obtain the 2nd region IMAQ optical parametric corresponding to n-quadrant in the same way, finally obtain N number of IMAQ optical parametric altogether.
Below for N be 2 and N 3 to illustrate.When N is 2, as shown in Figure 2, suppose in step s3 obtain personage place the 1st region IMAQ optical parametric specifically exposure value be+1EV, beyond personage, the exposure value in the 2nd region at background place is-2EV.When N is 3, as shown in Figure 2, suppose in step s3 obtain personage place the 1st region IMAQ optical parametric specifically exposure value be+1EV, the exposure value in the 2nd region at coco place is-1EV, and the exposure value in the region, region the 3rd beyond two regions is-2EV.
Next, step S4 is performed.
S4: control described image acquisition units and obtain image respectively based on described N number of IMAQ optical parametric, obtain an image collection.
In the embodiment of the present application, image collection comprises the N number of image corresponding with N number of region, specifically, is with N number of region N number of IMAQ optical parametric corresponding respectively, obtains N number of image, and content in N number of image is all identical.That is, be to obtain the image of identical content with each in N number of IMAQ optical parametric.
In specific implementation process, image acquisition units may have an IMAQ subelement, also may have multiple, the detailed process of IMAQ will be described with different situations below.
