Definition is higher than the definition of the second area in the first image 305 in addition to first area 306, in first area 306 and Fig. 4
The region that fenced up of focus frame 304 corresponding, so first area 306 is corresponding with the first subdomain 303.Therefore, real by this
Executing the method in example, electronic equipment can focus on specific reference object according to the demand of user, so shooting efficiency is more
High.
Further, the acquisition time of the preview image that the acquisition time of the first image 305 is later than in Fig. 4, because photosensitive unit
Part 102 obtains the speed of image quickly, so the difference of two width images is not very big, with the naked eye can't see.Certainly, if
In the moment preserving the first image 305, personage C squats down, then the position of first area 306 will not change, and definition is still
For the highest, simply the picture material of first area 306 may reform into wall.
Hereinafter a concrete example is lifted again so that the implementation process of the method to be described.
Such as user can also be in aforementioned personage A, personage B and personage C, for example, personage A, at this moment personage A
The camera function of mobile phone can be opened and is placed in a fixing position, choose the first pickup area, at this moment personage B and
Personage C can suffer in the first pickup area, then goes over and personage B and personage C stands together and prepares group photo, then
Personage A just by phonetic entry inform mobile phone oneself want focusing position at which, for example, face of personage C, then personage A
As long as just saying the name of personage C, then mobile phone will be focused automatically, and after focusing successfully, automatically starts fast
Door, preserves group photo image.Therefore, by the method can efficiently, be conveniently accomplished auto heterodyne, and need not be as prior art to set
Putting countdown, the user arranging countdown finally goes on camera site, because the time is the shortest, user may have little time to set
Take pictures posture, and be auto-focusing, can not focus on according to the wish of user；Hand-held without user in picture prior art
Mobile phone completes to autodyne, because the length of arm is limited, so the angle of shooting is the most effective, so preferably bat can not be obtained
