AE algorithm identifies the intense light source main body in first photo and second photo, described using in AE algorithm identification photo
Intense light source main body belongs to prior art scope, and details are not described herein again.The method can also operate determination according to the user's choice
Target object in first photo and second photo, for example, user can be in first photos and described
Circle selects target object respectively in second photo, and the method receives the circle selection operation of user, and according to circle selection operation determination
Target object in first photo and second photo.
In other embodiments of the present invention, the method can also be known by brightness determines first photo otherwise
With the target object in second photo, specifically, the method can identify in first photo that brightness value is greater than the
Image in the region of one predetermined luminance value is the image of target object, identifies that it is pre- to be greater than second for brightness value in second photo
If the image in the region of brightness value is the image of target object, wherein it is pre- that first predetermined luminance value is less than described second
If brightness value.
Step 304, synthesis the first image and second image, obtain Target Photo.
In the step, the method synthesizes the first image and second image, obtains target image, specifically,
It can be by the first image and second figure that the method, which synthesizes the first image and the mode of second image,
As being combined splicing, target image is obtained.It is understood that the first image is camera under the first exposure time
The intense light source image of shooting, the intense light source image that the as described camera is shot under compared with short exposure duration, can effectively prevent
Intense light source overexposure.Second image is the background image that camera is shot under the second exposure time, the as described camera
The background image shot under normal exposure duration can effectively prevent background image excessively dark.
