Description
Technical field
The present invention relates to camera technical field, more particularly to a kind of optical anti-vibration camera module and its control method.
Background technology
Generally, when camera is taken pictures, human hand inevitably produces shake, and the shake of hand can then cause
The change in optical signal that camera receives, and then to clap the situation that image quality decline occurs in picture, so in order to solve to image
Image quality caused by camera has shake when head is taken pictures declines, it is necessary to increase optical anti-vibration function in camera module.
The optical anti-vibration function of prior art is mainly adjusted by camera lens to compensate image caused by camera module is shaken
Skew, that is, need to be provided for the drive motor for driving camera lens movement below camera lens, so that the volume of camera module
Larger, next needs to set Hall sensor to feed back the position of camera lens, so that control system is more complicated, and works
When need to control camera lens to do X, Y-direction movement, such power consumption is larger.
The content of the invention
The technical problems to be solved by the invention are：There is provided it is a kind of take that small volume, control system be simple and power consumption compared with
Small optical anti-vibration camera module and its control method.
The technical solution adopted in the present invention is：A kind of optical anti-vibration camera module, including processor, lens assembly with
And gyroscope, gyroscope electrically connect with processor, the lens subassembly that can change focal position, and lens are additionally provided with outside lens assembly
Component electrically connects with processor.
The lens subassembly of focal position, which can be changed, to be included being formed as the optics silica gel of lens shape, is arranged on optics silica gel four
The piezoelectric ceramics and use of multiple focal positions for being used to extrude optics silica gel and then change the lens that optics silica gel is formed in week
In the glass cover-plate being fixed on optics silica gel and piezoelectric ceramics outside lens assembly, piezoelectric ceramics electrically connects with processor.
Piezoelectric ceramics is uniformly arranged on the circumference outside the optical active area of the lens of optics silica gel formation.
What the outer peripheral shape in optical active area of the lens for being shaped as being formed with optics silica gel of piezoelectric ceramics matched
Arc, and piezoelectric ceramics is at least four.
A kind of control method of optical anti-vibration camera module, it comprises the following steps：
（1）, gyroscope work, detect camera module jitter direction and shake angle；
（2）, processor receive the data that gyroscope sends over, first according to shake angle-data come be calculated need it is defeated
Enter the operating voltage of piezoelectric ceramics；
（3）And then processor selects the piezoelectric ceramics with jitter direction opposite location as work according to jitter direction data
Piezoelectric ceramics；
（4）, last processor is to the piezoelectric ceramics input service voltage that works so that work piezoelectric ceramics deformation, and then extrude light
Learn the focus that silica gel changes the lens that optics silica gel is formed.
Using above structures and methods compared with prior art, the present invention has advantages below：By being set outside camera lens
Variable focus lens package is put, so when camera lens is shaken, it is not necessary to adjust the position of camera lens, i.e., need not set responsible
Drive mechanism drives camera lens to move, and only needs to control the i.e. achievable stabilization of focus of Zoom lens, so takes body
Product is smaller, and control system is simple, and power consumption is also smaller.
And Zoom lens are formed by optics silica gel and piezoelectric ceramics, such processor can be controlled easily pair
The voltage of the piezoelectric ceramics of position is answered to control the focal position of lens, is so controlled more convenient and relatively simple for structure.
Piezoelectric ceramics is arranged on outside the optical active area of optics silica gel, does not interfere with the formation of optics silica gel thus
Lens normal work, reliability are higher.
The arc to match with edge that piezoelectric ceramics is done, so can preferably extrude optics silica gel, drive optics silica gel
The lens of formation, and at least provided with four, so can more accurately be focused.
And the jitter direction for detecting to obtain by gyroscope determines the piezoelectric ceramics specifically to pressurize, by shaking angle
Spend to determine the voltage added, so that it is more accurate when focusing, it can preferably play the function of stabilization.
