Specific embodiment
The embodiment of the present invention is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or has the function of same or like element.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
Below with reference to the accompanying drawings microshot processing method, device and the terminal device of the embodiment of the present invention are described.It needs
Bright, the microshot processing method of heaviness Fig. 1 of the embodiment of the present invention-Fig. 4 descriptions can be used for microshot and non-microspur
In the scene of shooting, it is preferable that following embodiment is grouped as microshot scene and is described：
Fig. 1 is the flow chart of microshot processing method according to an embodiment of the invention, as shown in Figure 1, this method
Including：
S110 obtains focusing request.
It is appreciated that the microshot processing method of the embodiment of the present invention, shooting work(is realized applied to by camera module
In the terminal device of energy, wherein, what kind of the camera lens composition of the camera module no matter shot is, image-forming principle is all convex
Lens imaging principle.
I.e. as shown in Fig. 2, when shooting subject distance camera lens distance be more than one times of focal length when, can on camera module,
Such as on the imaging sensor of camera module, what is obtained is the real image of photographed；When shooting subject distance camera lens away from
When from more than one times focal length is less than two focus length, what is obtained on the image sensing element of camera module is the photographed of amplification
Picture；When the distance of the subject distance camera lens of shooting is more than two focus length, obtained on the image sensing element of camera module
Be reduce photographed picture.
Wherein, convex lens formula is(u is distance of the photographed apart from camera lens, is properly termed as object distance；
V be the image distance of the photographed in being presented on camera module with a distance from camera lens, can become as away from the focal length that, f is camera lens,
Condenser performance by camera lens etc. determines), from convex lens formula, in the case where f is constant, phase is presented in the variation of v and u
Anti- variation tendency, i.e. u increase, then v reduces, and u reduces, then v increases.
And it is being taken the photograph with the style of shooting of the image of scenery amplified since microshot is a kind of shooting at close range
As module image sensing element on the obtained picture of photographed, the amplification factor compared to photographed should be more than or equal to
One.
Thus, when carrying out microshot, in order to see in view finder photographed clearly as, it is necessary to pass through tune
The size of whole image distance and object distance so that object distance u, that is, distance of the photographed apart from camera lens is more than one times of focal length, less than twice
Focal length, and the size of object distance and image distance meets above-mentioned convex lens formula as far as possible, the adjustment image distance and object distance with
See in view finder photographed clearly as process, alternatively referred to as focus.
It specifically, can be by obtaining focusing request in the microshot processing method of the embodiment of the present invention, it is determined whether
Object distance or the image distance of camera module are adjusted to adapt to present filming scene.
S120 judges whether motor stroke has reached capacity position.
S130, if so, being focused using MEMS control camera module movement.
In general, when camera module is used to carry out microshot, if the distance u of the scenery of distance of camera lens shooting is nearer,
Then for the ease of being focused on to photographed, can be contracted by the motor control camera lens in camera module to the opposite direction of shooting direction
It is short, to increase the size of u.
But limitation due to camera module space etc., the distance of the motor control camera lens receding in camera module are
Limited, for example the distance that camera lens shortens to the opposite direction of shooting direction can be only controlled as 6mm etc., thus, in camera lens
The distance of distance shooting is very close, even if control camera lens foreshortens to the extreme limit of travel of motor to the opposite direction of shooting direction,
The distance of distance of camera lens photographed is still smaller.
That is, the value of u is smaller at this time, if it is possible to it focuses to photographed, the value of v must be relatively large,
And the distance between camera module and camera lens obviously cannot meet the focus condition of camera module photographed at this time.
To solve the above-mentioned problems, the microshot processing method of the embodiment of the present invention introduces MEMS (micro
Electro-mechanical system, MEMS), when motor stroke reaches capacity position, the MEMS control can be passed through
Camera module movement processed, to realize the focusing to photographed, completes the microshot to photographed.
Wherein, MEMS grows up on the basis of microelectric technique (semiconductor fabrication), fusion
The high-tech electronic machine of the technologies manufactures such as photoetching, burn into film, LIGA, silicon micromachined, non-silicon micromachined and precision optical machinery processing
Tool device.
As shown in figure 3, MEMS includes fixed electrode 122, float electrode 124 and can deformation connector 126.Float electrode
124 coordinate with fixed electrode 122.Connector 126 is fixedly connected with fixed electrode 122 and float electrode 124.Fixed electrode 122 and
Float electrode 124 is used to generate electrostatic force under the action of driving voltage.Connector 126 is used under the action of electrostatic force along work
The direction deformation that moving electrode 124 moves is to allow float electrode 124 to move that camera module is driven to be moved.
Wherein, it is necessary to which explanation, according to the difference of concrete application demand, above-mentioned MEMS controls camera module moves every time
Step-length etc., can be demarcated according to lot of experimental data by system, also can voluntarily be set according to demand by user.And MEMS
More sensitive, flexibility is high, and the efficiency of control camera module movement is more efficient compared to what motor control camera lens moved, speed
Degree is faster.
Specifically, it can judge whether motor stroke reaches capacity position, for example, can be in horse after focusing request is obtained
Extreme position up to formation sets a sensor, when the sensor detects that motor reaches the position, can send motor stroke
Reach capacity the warning of position.
And then, it will be understood that extreme position is had reached due to motor stroke, cannot control the position of camera lens into
One step is moved to the opposite direction of shooting direction, so as to by MEMS that camera module is opposite to shooting direction
Direction is moved, i.e., by increasing the size of v, to expand the focusing range of camera module, allows camera module to larger model
Photographed in enclosing is focused.
For example, as shown in figure 4, when obtaining focusing request, if it is determined that motor stroke has reached extreme position A
Point, then MEMS can control the image sensing element in camera module to be moved, so as to work as MEMS control
Image sensing element is from A points to when being moved B points, and the size of v adds, according to convex lens image-forming discipline, the size of u
It adds, so as to expand the focusing range of camera module, improves the flexibility of microshot.
In conclusion the microshot processing method of the embodiment of the present invention, obtains focusing request, whether judges motor stroke
Reached capacity position, if so, being focused using MEMS control camera module movement.As a result, by micro electronmechanical
System control camera module movement focusing, expands focusing range, improves the flexibility of microshot.

Specifically, under due to handling scene in non-microshot, apart from camera lens farther out, i.e., u is larger for photographed, and microcomputer
The scope of the displacement distance of electric control shooting module is smaller, i.e. the excursion very little of v, therefore, in non-microshot Treatment stations
Under scape, had little significance using what MEMS control camera module movement was focused.
And under microshot scene, distance u of the photographed apart from camera lens is in one times of focal length between two focus length
Smaller value domain in, even if slightly adjust the distance between hypograph sensing element and camera lens v, such as control image sensor element to
Small distance is moved in the opposite direction of shooting direction, and it is apparent can so that focusing range increases.
For example, as shown in Fig. 6 (a), focusing is the camera module of f, distance, that is, picture of the camera module apart from camera lens
Away from for L1 when, according to convex lens formula, the distance of camera lens that can adjust the distance isObject carry out clearly into
Picture, when photographed is less than apart from distance of camera lensWhen, then it can not focus or focus and is inaccurate.
When to the opposite direction movable sensor of shooting direction, distance, that is, image distance of the camera module apart from camera lens is increased to
L2, according to convex lens formula, the distance of camera lens that can adjust the distance isObject carry out blur-free imaging, when
Photographed is less than apart from distance of camera lensWhen, then it can not focus or focus and is inaccurate.
And incite somebody to actionWithIt compares, obtained value isSince L1 is less than L2, becauseMore than 1, that is, image sensor element is controlled to the distance of the opposite direction movement L2-L1 of shooting direction so that
It can cause camera lens to existIt arrivesIn the range of, still can accurately it focus, and this increased scope pair
For one times of codomain scope to twice of focal length be it will be apparent that thus microshot processing method of the present invention microspur is clapped
It takes the photograph, there is very high feasibility.
Thus, in order to increase the practicability of the microshot method of the embodiment of the present invention, it is thus necessary to determine that current shooting pattern
