Embodiment one
Before introducing the information processing method of the embodiment of the present application, the basic structure of the electronic equipment first method of the embodiment of the present application applied makes a presentation, and please refer to Fig. 4, and the electronic equipment in the embodiment of the present application, comprising:
First image acquisition units 1, for carrying out in the process of IMAQ in the first image acquisition units 1 pair of pickup area, determine N number of first exposure parameter of N number of subregion of described pickup area, and obtain the first image corresponding to described pickup area based on described N number of first exposure parameter;

Processor 3, for synthesizing described first image and described second image, to obtain composograph corresponding to described pickup area.
Below the first information processing method in the application is described in detail, please refer to Fig. 1.
S1: carry out in the process of IMAQ to pickup area in described first image acquisition units, determines N number of first exposure parameter of N number of subregion of described pickup area, and obtains the first image corresponding to described pickup area based on described N number of first exposure parameter.
In the embodiment of the present application, before step S1, in order to obtain different exposure parameters, and by different exposure parameters, zones of different being exposed, needing pickup area to be divided into N number of subregion.Wherein, N for being more than or equal to 2, as 2,4,7, etc., the concrete value of N does not do concrete restriction in this application.
In the embodiment of the present application, be introduced with following two kinds of dividing mode, in specific implementation process, be not limited to following two kinds of dividing mode.
The first: according to the monochrome information of pickup area, pickup area is divided into N number of subregion.
Specifically, for N for 2, 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.
Concrete, as shown in Figure 2, the region at sun place is the 1st subregion, and the region at sky place is the 2nd subregion, and the region at hills and mountains place is the 3rd subregion.
The second: according to the positional information of pickup area, is divided into N number of subregion by pickup area.
In specific implementation process, as shown in Figure 3, suppose that N is 4, then pickup area is divided into 4 regions up and down.
Next, step S1 is specifically described.
In order to be described S1, for the first exposure parameter of the 1st subregion in N number of subregion, first the average brightness of the 1st subregion is obtained by area metering, for the 1st subregion, the exposure parameter of adjustment current region, as exposure value, can be that user manually adjusts, also can be that electronic equipment adjusts automatically, until current exposure parameter meets corresponding with the 1st subregion first pre-conditioned, as: when making the average brightness of each zonule meet a certain functional relation, determine that current exposure parameter is the first exposure parameter that the 1st subregion is corresponding.Further, when determining the exposure parameter of the 1st subregion, only according to the average brightness of the 1st subregion, and the no matter brightness value of other subregions in pickup area.
Next, determine the first exposure parameter that the 2nd subregion is corresponding to n-quadrant in the same way, finally determine N number of first exposure parameter of N number of subregion.
Below for N be 2 and N 3 to illustrate.When N is 2, suppose in step sl obtain sun place the 1st subregion exposure parameter specifically exposure value be-1EV, the exposure value in the 2nd region at the background place beyond the sun is+2EV.When N is 3, suppose in step sl obtain sun place the 1st region exposure parameter specifically exposure value be-1EV, the exposure value in the 2nd region at sky place is+1EV, and the exposure value in the region, region the 3rd beyond two regions is+2EV.
In the embodiment of the present application, after S1 determines N number of first exposure parameter of N number of subregion, obtain the first image corresponding to described pickup area based on described N number of first exposure parameter.
Specifically, take exposure parameter as exposure value be example, S1 is described.Certainly, the exposure parameter in the application can be also photosensitivity, and the application does not limit this.
In the embodiment of the present application, obtain the first image corresponding to described pickup area based on described N number of first exposure parameter, concrete methods of realizing is:
Get i successively from 1 to N, control described first IMAQ subelement, with described i-th exposure value, i-th exposure is carried out to described i-th sub regions;
When i is N, complete the exposure to described pickup area, obtain described first image, i is the integer between 1 to N.
Next, for N for 3, above-mentioned implementation method is described.
First, with the 1st the first exposure value that the 1st subregion is corresponding, 1st subregion is exposed, then with the 2nd the first exposure value that the 2nd subregion is corresponding, 2nd subregion is exposed, with the 3rd the first exposure value that the 3rd subregion is corresponding, 3rd subregion is exposed again, in specific implementation process, also can carry out the exposure of this 3 sub regions, the application does not limit this simultaneously.
Concrete, please continue to refer to Fig. 2, take pictures in process in the first image acquisition units, control to expose with the 1st subregion of the exposure value of-1EV to sun place, control to expose with the 2nd subregion of the exposure value of+1EV to sky place, control to expose region the 3rd subregion beyond two regions with the exposure value of+2EV, finally complete the exposure of 3 sub regions, obtain the first image.
In specific implementation process, after obtaining the first image, although expose for the different exposure values of every sub regions, the picture obtained can ensure that the effect in each region is better than carrying out exposure for whole pickup area and obtains picture, but the different luminance part in region do not obtain best effect.
Therefore, while carrying out step S1, carry out step S2: carry out in the process of IMAQ in described second image acquisition units to described pickup area, based on described N number of first exposure parameter, determine N number of second exposure parameter of described N number of subregion, wherein, different and satisfied first pre-conditioned between i-th the second exposure parameter of the i-th sub regions in described N number of subregion and i-th the first exposure parameter of described i-th sub regions, and obtain the second image corresponding to described pickup area based on described N number of second exposure parameter.
Specifically, in the embodiment of the present application, based on described N number of first exposure parameter, determine N number of second exposure parameter of described N number of subregion, concrete methods of realizing is:
When described first exposure value is greater than a threshold value, determine that described second exposure value is less than described first exposure value, described first pre-conditioned to make to meet between described first exposure value and described second exposure value; Or
When described first exposure value is less than described threshold value, determine that described second exposure value is greater than described first exposure value, described first pre-conditioned to make to meet between described first exposure value and described second exposure value.
Wherein, first is pre-conditionedly: when described first exposure value is greater than a threshold value, described second exposure value is less than described first exposure value, when described first exposure value is less than described threshold value, determines that described second exposure value is greater than described first exposure value.In specific implementation process, threshold value can have multiple, as: 2,3, or 5, the application does not limit this.
Next, be 1 and 2 with the number of threshold value to be described step S2.
When the number of threshold value is 1, when described first exposure value is greater than threshold value, determine that described second exposure value is less than the first exposure value, when described first exposure value is less than threshold value, determine that described second exposure value is greater than the first exposure value.In specific implementation process, the brightness of all right passing threshold combining environmental light, second exposure value of the second image acquisition units is determined, as: when ambient light is partially dark, first exposure value of the first image acquisition units is high exposure value, then the second exposure value of the second image acquisition units can for being less than the high exposure value of the first exposure value, and when ambient light is partially bright, first exposure value of the first image acquisition units is low exposure value, then the second exposure value of the second image acquisition units can for being greater than the low exposure value of the first exposure value; When ambient light is normal, first exposure value of the first image acquisition units is high exposure value, then the second exposure value of the second image acquisition units can be low exposure value, and the first exposure value of the first image acquisition units is low exposure value, then the second exposure value of the second image acquisition units can be high exposure value.
In above three kinds of situations, controlled by the complementation of the first exposure value and the second exposure value, and then obtain preferably synthesising picture.
Concrete, given threshold is+1EV, when ambient light is partially dark, first exposure value of the first image acquisition units is+2EV, although the first exposure value is high exposure value, but because ambient light is partially dark and the first exposure value is greater than threshold value, then the second exposure value of the second image acquisition units determined can for being less than the high exposure value of the first exposure value, as: can be+1EV or+0.5EV; Given threshold is-0.5EV, when ambient light is partially bright, first exposure value is-1EV, because the first exposure value is less than threshold value, then determine that the second exposure value of the second image acquisition units can for being greater than the low exposure value of-0.5EV, as :-0.2EV or-0.3EV, the application does not limit this.
When the number of threshold value is 2, be respectively first threshold and the Second Threshold being greater than first threshold, when described first exposure value is greater than Second Threshold, determine that described second exposure value is less than the first exposure value, when the first exposure value is between first threshold and Second Threshold, determine that described second exposure value is arbitrary value, and when described first exposure value is less than first threshold, determine that described second exposure value is greater than the first exposure value.
Concrete, suppose that first threshold is for-0.5EV, Second Threshold is+0.5EV, when ambient light is partially dark, first exposure value of the first image acquisition units is+2EV, because ambient light is partially dark and the first exposure value is greater than Second Threshold, then the second exposure value of the second image acquisition units determined is the high exposure value being less than the first exposure value, as :+0.5EV or+1EV; Suppose that first threshold is for-0.5EV, Second Threshold is+0.5EV, and the first exposure value is+0.2EV, because the first exposure value is between first threshold and Second Threshold, second exposure value of the second image acquisition units then determined can be arbitrary value, as :-0.5EV or+1EV; Suppose that first threshold is for-0.5EV, Second Threshold is+0.5EV, when ambient light is partially bright, first exposure value is-1EV, because ambient light is partially dark and the first exposure value is less than first threshold, the second exposure value then determined is the low exposure value-0.5EV or-0.7EV being greater than the first exposure value-1EV, and the application does not limit this.
Next, please continue to refer to Fig. 2, the 1st the first exposure value continuing to use the 1st subregion of pickup area is-1EV, 2nd the first exposure value of the 2nd subregion is+1EV, 3rd the first exposure value of the 3rd subregion is the example of+2EV, threshold value is+0.5EV, in order to the image detail obtained is more clear, then carry out in the process of IMAQ in the second image acquisition units to pickup area, 1st the second exposure value of the 1st subregion of the pickup area determined can for being greater than the low exposure value of-1EV, as :-0.5EV, 2nd the second exposure value of the 2nd subregion can for being less than the high exposure value of+1EV, as :+0.7EV, 3rd the second exposure value of the 3rd subregion can for being less than the high exposure value of+2EV, as :+1.5EV.Certainly, the one or more data in above-mentioned example are only used to illustrate and enumerate, and in specific implementation process, technical staff belonging to the application can select according to actual needs, and the application does not do concrete restriction.
In step s 2, obtain the specific implementation of the second image corresponding to described pickup area based on N number of second exposure parameter determined, please refer in step S1 the implementation method obtaining the first image, repeat no more herein.
After acquisition first image and the second image, perform step S3: HDR process is carried out, to obtain described composograph to described first image and described second image.
In the embodiment of the present application, by two Images uniting one, HDR technology is adopted to synthesize.Synthesize with the image that the ratio of regulation is corresponding to different exposure parameter, such as, give the weights that image corresponding to different exposure parameter is different, carrying out addition process.Because HDR technology repeats no longer one by one for those skilled in the art grasp therefore the application.
After carrying out HDR synthesis, in order to ensure can, better close to true picture, also needing to carry out interpolation, the process such as denoising of composograph, the final composograph obtaining best results.
