Abstract
The utility model discloses a kind of optical anti-vibration and move camera module, comprise camera lens, Hall element, shift shaft type 3 axle voice coil motor, gyro sensor, OIS control and drive system, AF driving chip, cmos sensor; Wobble information is converted into the signal of telecommunication and sends OIS control and drive system to by gyro sensor, OIS control and drive system promotes shift shaft type 3 axle voice coil motor, control camera motion, the positional information of camera lens is fed back to OIS control and drive system by Hall element, forms closed-loop control.The beneficial effects of the utility model are, effectively can reduce the impact of artificially shaking and bringing imaging picture.Compared with camera module in the past, effectively can improve the influence degree to picture that human factor causes, improve user's user satisfaction, improve product market share.
Description
technical field
The utility model relates to the field of camera module image system, is specially a kind of optical anti-vibration and moves camera module.
Background technology
During hand-held intelligent mobile phone photograph, the shake of hand can cause the slight inclination (generally within +/-0.5 degree) of camera, this inclination causes the change of camera lens viewing angle, take camera lens as object of reference, the object being equivalent to be taken moves, therefore imaging also can offset relative to original position on the image sensor, and result causes image to play pendulum with the shake set about all the time.For addressing this problem, OIS technology is arisen at the historic moment.OIS is the abbreviation of optical image stabilizing system.First it should comprise the gyroscope that can sense hand shaking, the camera tilt angles degree that hand shaking causes by this gyroscope is measured, system dopes the image shift amount tilting to cause again according to this angle, then Systematical control camera lens produces formed objects relative to Image sensor shift but the contrary image shift in direction, thus the image shift that hand shaking causes is balanced out, ensure that camera still can keep image stabilization in hand shaking environment.
It is noted that the image shift that the OIS technology correction camera at present in mobile phone module tilts to cause, and do not process camera translation up and down and shake the image problem caused.In fact, when taking distant place scenery, the image shift produced is shaken in camera translation not can think to exist, without the need to OIS system balance.Judder comes from the inclination shake of camera completely.But when clapping microspur, the impact of camera translation shake can reveal gradually.Current mobile phone OIS camera module, in order to avoid too complicated system architecture, selects the microshot problem ignoring translation shake generation.
Utility model content
The utility model object is to overcome the deficiencies in the prior art, proposes a kind of novel optical anti-vibration and moves camera module, solve following technical problem: 1) camera is to complete defocused, then presses machine shake when taking pictures key; 2) carry out night scene to take pictures the shake of staff when needing time exposure; 3) human body shake during long-time handheld device is needed when carrying out video record.
The technical solution of the utility model is: a kind of optical anti-vibration moves camera module, comprises camera lens, Hall element, shift shaft type 3 axle voice coil motor, gyro sensor, OIS control and drive system, AF driving chip, cmos sensor; Wobble information is converted into the signal of telecommunication and sends OIS control and drive system to by gyro sensor, OIS control and drive system promotes shift shaft type 3 axle voice coil motor, control camera motion, the positional information of camera lens is fed back to OIS control and drive system by Hall element, forms closed-loop control.
The beneficial effects of the utility model are, effectively can reduce the impact of artificially shaking and bringing imaging picture.Compared with camera module in the past, effectively can improve the influence degree to picture that human factor causes, improve user's user satisfaction, improve product market share.
accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of camera module.
Fig. 2 is the circuit module schematic diagram of camera module.
Embodiment
Below in conjunction with drawings and Examples, set forth the utility model further.As shown in Figure 2, optical anti-vibration moves camera module, comprises camera lens 1, Hall element 2, shift shaft type 3 axle voice coil motor 3, gyro sensor 4, OIS control and drive system 6, AF driving chip 7(move for CD-ROM drive motor), cmos sensor 8; Wobble information is converted into the signal of telecommunication and sends OIS control and drive system to by gyro sensor, OIS control and drive system promotes shift shaft type 3 axle voice coil motor, control camera motion, the positional information of camera lens is fed back to OIS control and drive system by Hall element, forms closed-loop control.
As shown in Figure 1, the shift shaft type 3 axle voice coil motor of this module is arranged on FPC plate 9, and camera lens is arranged on motor, FPC plate is also provided with gyro sensor, OIS control and drive system.
Common AF module moves adjusting focal length by the vertical direction of motor, and in the utility model, adopt shift shaft type 3 axle voice coil motor, by gyroscope, OIS control and drive system, the common co-ordination of this three part of shift shaft type 3 axle voice coil motor reaches the effect of stabilization.Vertical direction can not only move motor, can also mobile motor in horizontal direction.The convert information of shake becomes the signal of telecommunication to give OIS control and drive system by gyroscope, the motion of OIS control and drive system promotion motor control suspension camera lens carrys out the impact of compensate for jitter generation, Hall element feeds back to OIS control and drive system the positional information of camera lens, thus forms closed-loop control.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
