In the embodiment of the present invention, the region of camera shooting is referred to as view area, and the scene in view area is presented on into screen
When on curtain, the picture on screen is referred to as interface of finding a view, it is seen then that and interface of finding a view is corresponding with view area, namely：Find a view interface
It is the picture that view area is presented on screen.
In the embodiment of the present invention, it is assumed that the size at interface of finding a view and terminal screen it is in the same size, certainly, interface of finding a view
Size might be less that the size of terminal screen, namely：Interface of finding a view occupies a part for screen.In order to distinguish interface of finding a view
Main body and background, and consider that main body is normally at the central area at interface of finding a view, using the central area at interface of finding a view as mesh
Region is marked, this target area that is to say body region.In one embodiment, target area occupies the 1 of interface of finding a view, 4, when
So, the size of target area and position not limited to this.
In the embodiment of the present invention, because the size of subject is possible to smaller relative to target area, therefore, in order to more
Accurately subject is focused, target area is refined.Specifically, target area is divided into N number of subregion.
In one embodiment, the size all same of every sub-regions in N number of subregion.In another embodiment, N number of subregion
In every sub-regions size it is different or the sizes of part subregion are different.Fig. 5 is the camera of the embodiment of the present invention
Find a view the schematic diagram two at interface, as shown in figure 5,1,4 regions (namely target area) at interface center of finding a view are divided into 5 × 5
25 sub-regions (namely N=25).It will be appreciated by those skilled in the art that the division of target area is not limited to shown in Fig. 5
Mode, can also be divided by other means.

In the embodiment of the present invention, focusing is carried out to the object in the focusing area and uses Autofocus Technology.From basic
For principle, auto-focusing is segmented into two major classes：One kind is the ranging based on range measurement between camera lens and the target that is taken
Auto-focusing, another kind of is the focus detection auto-focusing based on imaging clearly on focusing screen.
Illustrate focus process by taking focus detection auto-focusing as an example below：The focal length of camera is adjusted, obtains different focal
The image at corresponding interface of finding a view；When the definition maximum of the image in the focusing area in the interface of finding a view,
Determine current focus focusing focal length corresponding to the focusing area.
Above-mentioned focus detection auto-focusing mainly has contrast method and phase method, wherein：
1) contrast method, this method are to realize auto-focusing by the contour edge of detection image.The profile side of image
Edge is more clear, then its brightness step is bigger, and the contrast between edge scenery and background is bigger in other words.Conversely,
Image out of focus, contour edge is smudgy, and brightness step or contrast decline；Out of focus more remote, contrast is lower.Utilize this
Principle, two photoelectric detectors are placed on equidistance before and after charge coupled cell (CCD, Charge-coupled Device)
Place, by the image of photography thing by light splitting simultaneously into the contrast on the two detectors, exporting its imaging respectively.When two
During the absolute value minimum for the contrast difference that detector is exported, illustrate the image planes of focusing just among two detectors, i.e.,
Approached with CCD imaging surface, then focusing is completed.
2) phase method, this method are to realize auto-focusing by detecting the offset of picture.One is placed in CCD position
The waffle slab being made up of parallel lines, lines are in succession printing opacity and light tight.After network board on appropriate location with optical axis symmetrically
Place two photo detectors.Network board with it is of reciprocating vibration in optical axis vertical direction.When focusing surface overlaps with network board, pass through
The light of waffle slab printing opacity lines reaches two photo detectors behind simultaneously.And when defocus, light beam can only successively reach two
Individual photo detector, then there is phase difference between their output signal.Dephased two signals are after processing of circuit
Control executing agency to adjust the position of object lens, focusing surface is overlapped with the plane of waffle slab.
In one embodiment, the focusing method is further comprising the steps of：
