Description
Technical field
The present invention relates to a kind of device against shake being applied to picture pick-up device, especially there is mobile phone of camera function etc. just
The shift shaft type optical anti-vibration taking formula digital equipment moves lens driver.
Background technology
There is the portable digital equipments such as the mobile phone of camera function, its camera focusing is different with general camera, Qian Zheyin
The position of photo-sensitive cell can not be adjusted for the reason miniaturization, so its focus function is substantially integrated in ISP (figure
As signal processor) in set of image data collection and processing method.After view finder captures the image of most original, these
View data can be taken as firsthand information to be sent in ISP, and now ISP will be analyzed to initial data, in check image
Density variation between adjacent pixels.If the focusing of original image is inaccurate, then the picture element density adjoining will very
Close, and now ISP has a set of algorithm image data acquiring is adjusted, this process is by the lens unit of camera
Lock voice coil motor (VCM) to realize.Voice coil motor is mainly made up of coil, group of magnets and shell fragment, and lens unit is locked in
In coil, coil is fixed between group of magnets by upper and lower two shell fragments.The electrical current of ISP control coil, coil electricity meeting
Produce magnetic field, coil magnetic field and magnetite group interact, coil and the lens unit being locked in coil just together with move and move up and down
Focusing, until the focusing that ISP calculates original image is accurate；When power is off, coil resets under shell fragment elastic force, thus
Achieve automatic focusing function.
Impact image quality being caused for operator's hand shaking when solving to shoot, present domestic and international application is micro- in mobile phone etc.
The optical anti-vibration of small-sized image pickup equipment moves lens driver mainly two kinds of structures：A kind of is parallel-moving type, and another kind of is to move axle
Formula.
Parallel-moving type optical anti-vibration moves lens driver, to control lens unit along Z axis phase using actuation means (as VCM)
Vertical movement is done for photo-sensitive cell and realizes automatic focusing function, also add other actuation means (as VCM) and control lens list
Unit does compensatory moving in parallel along XY axle with respect to photo-sensitive cell and realizes stabilization function, and after device power-off, lens unit exists
Reset under the elastic force of the elastic piece structure of VCM.In traditional design, two kinds of actions are orthogonal because of the direction of motion, each need to have solely
Vertical suspension and electromagnetism power-driven system, to detect moving direction along with also having needed displacement transducer such as Hall element
And amount of movement, so such device structure is extremely complex, workpiece is many and workpiece accuracy requirement is high, and assembling is extremely difficult, produces
Efficiency and yield are all very low, and especially small product size is larger, and the small size requirement with mobile phone or Portable image pickup equipment has larger
Conflict.
As the Chinese patent for CN102445811A for the notification number " has and fills for the image taking compensating handshaking function
Put " just belong to the improvement of the dynamic lens driver of such parallel-moving type optical anti-vibration so as to achieve miniaturization.But research table
Bright it is assumed that object (subject)-camera imaging face-eyeglass face be parallel if it is further assumed that camera shake also simply up and down/
Left and right (X/Y axle) shake, makes three planes still be held under parallel state, parallel-moving type stabilization " in theory " is to make
Go out perfect hand shaking to compensate；And take pictures in experience in real, in particular with the miniaturization of shooting equipment, mobile phone etc. is portable
During the taking pictures of digital equipment, camera is difficult to subject under a parastate, and more or less, mobile phone etc. is just
The sensitive chip taking formula digital equipment is existed with the object taken pictures and has an angle, parallel-moving type stabilization in this case
The limited use of lens driver, especially generally requires to sacrifice the quality at imaging region edge while stabilization.
Shift shaft type optical anti-vibration moves lens driver, be provided with several groups of actuation means control lens units along Z axis with respect to
Photo-sensitive cell does vertical movement and realizes automatic focusing function, and have concurrently control lens unit do along XY axle with respect to photo-sensitive cell
Compensatory moving in parallel realizes stabilization function, and after device power-off, lens unit is in the elastic force of the elastic piece structure similar to VCM
Lower reset.Theoretical according to force resolution, can by both the above action, drive the power of lens unit be decomposed into two groups parallel to
The opposite direction active force of optical axis, therefore be can achieve using a set of suspension and drive system.This class formation is relatively simple, raw
Produce assembling to be easier, production efficiency and yield are all higher, and small volume, the little of mobile phone or Portable image pickup equipment can be met
Type, lightening requirement.But the device of this class formation is in order to realize auto-focusing, regardless of whether needing in each shooting process
Carry out stabilization compensation and all must drive whole actuation means it is clear that power consumption increases, the endurance of equipment is had greatly
Impact.Move lens driver as the Chinese patent for CN10152348B for the notification number just belongs to such shift shaft type optical anti-vibration.
