Take pictures owing to opening photoflash lamp in the ban, then when adopting overlength exposure to take pictures, its process of taking pictures is similar to the above, does not repeat them here.
Specifically, longitudinal position information is obtained by least two camera measurements, be specifically described for the photographing device of dual camera, as shown in Figure 4, distance between camera 400 and camera 401 is d1, distance between a pixel 402 to photographing device of taking pictures on thing is d2, angle between camera 400 and a pixel 402 of taking pictures on thing is θ, angle between camera 401 and pixel 402 is α, pass through d1, θ, α calculates d2, d2 is the distance that the pixel 402 of taking pictures on thing arrives photographing device, pixel all on thing of taking pictures then forms the longitudinal position information of thing of taking pictures to the distance of photographing device.In selected region, the longitudinal position information of all things of taking pictures forms depth of field map.
Wherein, the longitudinal position information of thing of taking pictures in selected region can in the pre-test of step 100, also can measure after step 100 or step 101 or step 102, as long as in the pre-test of step 103, and step 100, step 101, there is no inevitable sequencing between step 102.
For determining the main body of taking pictures in the second image more accurately, optionally, according to the longitudinal position information of thing of taking pictures in photoflash lamp illuminated area, determine the main body of taking pictures in described second image.
Specifically, by thing of taking pictures identical with the longitudinal position information of thing of taking pictures in described photoflash lamp illuminated area in described second image, as the main body of taking pictures in described second image;
Wherein, the longitudinal position information of thing of taking pictures in described photoflash lamp illuminated area is determined by least two cameras.
Be specifically described for Fig. 2, the first image 1 obtained is exposed by overlength, the second image 2 is obtained by opening photoflash lamp, suppose that the region that photoflash lamp illuminates is 202, by the longitudinal position information of the thing of taking pictures of at least two camera determination photoflash lamp illuminated area, suppose that the longitudinal position information of the thing of taking pictures of photoflash lamp illuminated area is 1.5 meters, then the thing of taking pictures being 1.5 meters by longitudinal position information in the second image 2 is defined as main body of taking pictures.As shown in Figure 2, the longitudinal position information of the thing of taking pictures in 202 regions is 1.5 meters, then the thing of taking pictures in 202 regions is defined as main body of taking pictures.
It should be noted that, in embodiments of the present invention, longitudinal position information is take pictures thing to the distance between photographing device in selected region.The measurement of the second longitudinal position information can before taking pictures to selected region, or in the process of taking pictures to selected region, also can be both after taking pictures to selected region.
It should be noted that the main body of taking pictures in the second image is the main body of taking pictures in the first image, is also simultaneously the main body of taking pictures in selected region.
As shown in Figure 2,202 regions in the second image 2 are replaced in 200 regions in the first image 1, obtains target image 3, namely target image 3 is made up of 202 regions and 201 regions.
Because in the first image 1, the brightness value of 201 area pixel is greater than the brightness value of the pixel in 203 regions in the second image 2, in second image 2, the brightness value of 202 area pixel is greater than the brightness value in 200 regions in the first image 1, and the effect of the image of the target image 3 therefore obtained is better.
Optionally, after step 101 determines the main body of taking pictures in described second image, the longitudinal position information of main body of determining to take pictures in described second image is different from the longitudinal position information of other things of taking pictures in described second image, then perform step 102, determine the identical image with main body of taking pictures in described second image in described first image
Be specifically described for Fig. 5 (a), if the longitudinal position information of main body 502 of taking pictures in the second image 501 is as different in the longitudinal position information of thing 503 in the second image 501 of taking pictures from other things of taking pictures in the second image 501, photographing device is by image 502 identical with the longitudinal position information of main body 502 of taking pictures in the second image 501 in the first image 500, replace with the main body 502 of taking pictures in the second image 501, obtain target image 504.
If described in the take pictures longitudinal position information of main body identical with at least one other thing longitudinal position information in described second image of taking pictures in described second image, optionally, after main body of taking pictures described in determining, by in described first image with the longitudinal position information of main body of taking pictures in described second image, image that horizontal direction positional information is all identical with vertical direction positional information, replace with the main body of taking pictures in described second image, obtain target image.

Calculate for simplifying, a kind of optional implementation is: described second image is divided into multiple subregion, and according to the brightness value of pixel each in described subregion, determines the brightness value of described subregion;
Determine that brightness value exceedes the subregion of setting threshold;
All brightness values are exceeded the image in the subregion of setting threshold, as the main body of taking pictures in described second image.
Such as: when the size of image is [W, H], wherein W is the width of image, and H is the height of image, image is divided into m*m sub regions, and m value is larger, and the effect of the target image of generation is better, but corresponding amount of calculation increases, therefore under normal circumstances, preferably, m gets 16 or 32.
Be specifically described for Fig. 6, the first image 01 obtained is exposed by overlength, the second image 02 is obtained by opening photoflash lamp, and target image 03, second image 02 is divided into 64 sub regions, i.e. m=8, the brightness value of every sub regions is obtained by the mean value of the brightness value calculating all pixels in every sub regions, such as, the brightness value of subregion a is 18, be greater than the threshold value 15 of setting, count in the second image 02 all subregion a ~ p being greater than the threshold value of setting, the image be then made up of subregion a ~ p is the main body of taking pictures in the second image.
Wherein, the threshold value of setting sets according to actual conditions, and the threshold value value of general setting is 15.
When the second image is divided into other multiple subregions, mode and the said method of its generation target image are similar, do not repeat them here.
Owing to only needing in the method to judge whether the region divided is greater than the threshold value of setting, and judge whether the brightness value of each pixel is greater than compared with the brightness value of default pixel, simplifies the workload of calculating, improves efficiency.
It should be noted that, in the embodiment of the present invention, be not limited by the main body of taking pictures that pixel intensity is determined in the second image, the method for other main bodys that can be used in determining taking pictures in the second image.
