Description
Technical field
The utility model relates to a kind of device against shake being applied to picture pick-up device, and the shift shaft type optical anti-vibration especially with portable digital equipments such as the mobile phones of camera function 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, the former is because the reason of miniaturization can not adjust the position of photo-sensitive cell, so its focus function is be integrated in a set of image data acquiring in ISP (image-signal processor) and disposal route in essence.After view finder captures the most original image, these view data can be taken as source book and be sent in ISP, and now ISP just can analyze raw data, the density variation in check image between adjacent pixels.If the focusing of original image is inaccurate, the picture element density so adjoined will be very close, and now ISP has a set of algorithm to image data acquiring and adjusts, this process the lens unit of camera is locked voice coil motor (VCM) to realize.Voice coil motor is formed primarily of coil, group of magnets and shell fragment, and in coil, coil is fixed between group of magnets by upper and lower two shell fragments in lens unit locking.The electrical current of ISP control coil, coil electricity can produce magnetic field, and coil magnetic field and magnetite group interact, coil be locked in the lens unit in coil just together with move and move up and down focusing, until the focusing that ISP calculates original image is accurately; When power is off, coil resets under shell fragment elastic force, so just achieves automatic focusing function.
In order to the impact that operator's hand shaking when solving shooting causes image quality, present domestic and international application is moved lens driver in the optical anti-vibration of the microminiature picture pick-up devices such as mobile phone and is mainly contained two kinds of structures: a kind of is parallel-moving type, and another kind is shift shaft type.
Parallel-moving type optical anti-vibration moves lens driver, adopt actuating device (as VCM) to control lens unit to do vertical movement along Z axis relative to photo-sensitive cell and realize auto-focus function, also add other actuating devices (as VCM) to control lens unit and do compensatory moving in parallel along XY axle relative to photo-sensitive cell and realize stabilization function, after device power-off, lens unit resets under the elastic force of the elastic piece structure of VCM.In traditional design, two kinds of actions because of direction of motion orthogonal, respective need have independently suspension and electromagnetic force drive system, add and also needed displacement transducer such as Hall element to detect moving direction and amount of movement, so such device structure is very complicated, workpiece is many and workpiece accuracy requires high, assemble very difficult, production efficiency and yield are all very low, and especially small product size is comparatively large, requires larger conflicting with the small size of mobile phone or Portable image pickup equipment.
Just belonging to as the notification number Chinese patent that is CN102445811A " has the image capturing device for compensating the function that hand shaking is moved " improvement that this type of parallel-moving type optical anti-vibration moves lens driver, having achieved miniaturization.But research shows, hypothetical target thing (subject)-camera imaging face-eyeglass face is parallel words, suppose camera shake also just shake up and down/left and right (X/Y axle) again, making three planes be still remains under parallel state, and parallel-moving type stabilization " in theory " can make perfect hand shaking to compensate; And reality take pictures experience in, particularly along with the microminiaturization of shooting equipment, the portable digital equipments such as mobile phone take pictures in process, camera is difficult to subject under a parastate, more or less, the sensitive chip of the portable digital equipments such as mobile phone exists with the object of taking pictures and has an angle, the limited use of parallel-moving type stabilization lens driver in this case, while stabilization, especially often need the quality of sacrificing imaging region edge.
Shift shaft type optical anti-vibration moves lens driver, be provided with several groups of actuating devices to control lens units and do vertical movement along Z axis relative to photo-sensitive cell and realize auto-focus function, and have concurrently and control lens unit and do compensatory moving in parallel along XY axle relative to photo-sensitive cell and realize stabilization function, after device power-off, lens unit resets under the elastic force of elastic piece structure being similar to VCM.Theoretical according to resolution of force, by above two kinds of actions, the power of lens unit can be driven to be decomposed into the opposite direction acting force that two groups are parallel to optical axis, therefore to adopt a set of suspension and drive system to realize.This class formation is comparatively simple, and production and assembly ratio is easier to, and production efficiency and yield are all higher, and small volume, the miniaturization of mobile phone or Portable image pickup equipment, lightening requirement can be met.But the device of this class formation is in order to realize auto-focusing, in each shooting process, all must drive whole actuating devices the need of carrying out stabilization compensation, obvious power consumption increases, and has extreme influence to the flying power of equipment.Lens driver is moved as the notification number Chinese patent that is CN10152348B just belongs to this type of shift shaft type optical anti-vibration.
