A kind of camera module

Technical field

The present invention relates to camera field, and in particular to a kind of camera module.

Background technology

Along with the development of optical image technology, camera module is widely used in various imaging device is as digital camera, video camera, specifically can be published in IEEE Transactions on Pattern Analysisand Machine Intelligence see people such as Rahul Swaminathan, Vol.22, document Nonmetriccalibration of wide-angle lenses and polycameras in No.10, October 2000.

Along with digital camera technology development, the fuselage of camera is often both little and light, easily because the vibrations in capture process cause light to correspond to the skew of the image space on camera module, and then causes filmed image fuzzy.Current anti-shake method is mainly divided into electronic type and optical profile type, wherein better with optical anti-shake effect.Optical anti-shake then can be divided into two kinds traditionally: one is that camera lens is shockproof, that is, according to vibrations direction and the degree of camera, the position of corresponding adjustment camera lens and angle, make compensation, makes light path keep stable; One is that image device is shockproof, that is, after perception camera shake, image sensor initiatively makes reverse movement, keeps image stabilization.No matter be that camera lens is shockproof or image device is shockproof, all need, actuator is set in camera module and moves that vibrations are compensated to drive camera lens or image sensor.

Auto-focusing use made by the existing actuator for camera module more, namely for driving camera lens module or image sensor to move along the optical axis direction of camera module.Such as, conventional voice coil motor comprises fixing fitted tube, movable accommodating cylinder, coil, magnet and brace.Described movable accommodating cylinder is coaxially arranged in fixing fitted tube, and drives it to be subjected to displacement for accommodating camera lens module or image sensor.Described coil and magnet are relatively arranged between fixing fitted tube and movable accommodating cylinder, for providing driving force.Described brace is used for the elastic-restoring force providing the optical axis direction along camera module to movable accommodating cylinder.
