Detailed description of the invention
Embodiments herein is described below in detail, and the example of described embodiment is shown in the drawings, the most from start to finish
Same or similar label represents same or similar module or has the module of same or like function.Below with reference to attached
The embodiment that figure describes is exemplary, is only used for explaining the application, and it is not intended that restriction to the application.On the contrary, originally
The embodiment of application includes all changes in the range of the spirit falling into attached claims and intension, revises and be equal to
Thing.
Along with the development of mobile terminal, the hardware in mobile terminal, also in constantly upgrading, such as, uses in mobile terminal
MEMS (Micro Electro Mechanical System, MEMS).Concrete, MEMS can apply multiple
In module, such as apply in imaging modules.Imaging modules includes camera lens, MEMS, imaging sensor (Sensor) etc., MEMS energy
Imaging sensor is enough driven to move.
MEMS grows up on the basis of microelectric technique (semiconductor fabrication), has merged photoetching, burn into thin
The high-tech electronic mechanical devices that the technology such as film, LIGA, silicon micromachined, non-silicon micromachined and precision optical machinery processing manufacture, compares

Fig. 1 is the schematic flow sheet of the lens zoom implementation method that one embodiment of the application proposes.
As it is shown in figure 1, the method for the present embodiment includes:
S11: object is carried out imaging in current location, obtains the image before position is moved.
During for example, it is desired to object is carried out imaging, can first adjust the distance between imaging sensor and camera lens is camera lens
The distance of focal length, reaches focusing state.After reaching focusing state, user presses the most behind the door, and imaging sensor can be to object
Carry out imaging.
S12: control MEMS and drive imaging sensor to move.
S13: position after movement again carries out imaging to described object, obtains the image after position is moved.
Unlike usual imaging mode once, in order to realize the effect of similar optical zoom, also in the present embodiment
Need control imaging sensor to carry out position to move, and position after movement again carries out imaging to object.
Concrete, imaging sensor can be the movement carried out under the drive of MEMS.With driving devices such as voice coil motors
Except for the difference that, MEMS can realize high-precision movement, such as can realize the movement of pixel scale, thus be implemented as sensing

The average of the pixel value of appropriate section in individual image.Such as, when moving the distance of half-pixel size, after second time is mobile every time
The image obtained moves the distance of 1 Pixel Dimensions relative to image when not moving, it is also assumed that the image before superposition is
N*M (N row M row) size, and assume that mobile is to move along column direction from left to right, then the pixel of lap
Number is N* (M-1), a left side for the part of N* (M-1) size on the right side of image when i.e. not moving and the second time image after mobile
There is overlap in the part of N* (M-1) size of side, therefore the size of the image after the two image overlay is N* (M+1), wherein,

Value is the pixel value of the string of the rightmost side of the image after second time moves, and the part of the N* of centre (M-1) size is each
The pixel value of pixel is the average of the respective pixel values of two image sections of above-mentioned existence overlap.
Further, above-mentioned mobile number of times can pre-set, and maximum mobile number of times can be able to move according to MEMS
Dynamic ultimate range determines.Such as, the distance of the most mobile half-pixel size, then the maximum times that can move=take downwards
Whole (X/0.5), wherein, X is the ultimate range that MEMS can move, in units of Pixel Dimensions, can be true according to hardware parameter
Fixed.Round downwards (X/0.5) and represent the max-int less than X/0.5.
