Description
Technical field
The utility model relates to apparatus for making a video recording field, in particular to a kind of focusing motor.
Background technology
Smart mobile phone height is universal, wherein the photographic effect of smart mobile phone is the major criterion that cellphone subscriber chooses mobile phone, for the photographic effect that makes mobile phone is further drawn close to digital camera, many internationally recognizable mobile phone focusing motor manufacturer all starts to research and develop three axle focusing motor, makes cell-phone camera module possess stable (OIS) function of optical image.Current smart mobile phone OIS camera module has two kinds of technology paths, is respectively based on parallel-moving type (Pure shift) OIS focusing motor and based on shift shaft type (Tilt-shift) OIS focusing motor.
Parallel-moving type OIS focusing motor be by one independently AF autofocus motor be fixed in a translation suspension and (be generally 4 isometric suspensions straight up), this suspension allows this AF motor to do small translation (generally in positive and negative 100 microns) along any direction in the plane that is parallel to imageing sensor.Because the total weight of camera lens suspended substance is larger, and the hardness of suspension is limited, therefore, under different photography postures (down, level forward, towards first-class), camera lens suspended substance can produce translation with respect to imageing sensor under the effect of self gravitation, more seriously, camera lens suspended substance (being equivalent to a spring oscillator) can produce translational vibration under external disturbance, causes image blurring.The advantage of parallel-moving type closed loop OIS motor is: in theory can the large shake of compensate for slower, and maximum offset angle can reach positive and negative 1.5 degree.Its special translation suspension has solved the three-dimensional translating problem of camera lens, and camera lens, in the time doing translation, still can ensure that optical axis is perpendicular to image sensor surface.Its shortcoming is: structure is complicated more a lot of than conventional motor, and Material Cost is high, and manufacturing process is loaded down with trivial details, and low yield, low yield and the high price brought thus, is unfavorable for the spread of OIS technology.
The structure of shift shaft type OIS motor is relatively simple a lot, approaches very much common AF motor.Difference is, the spring suspension system of common AF motor only allows camera lens to move along focusing direction, and the spring suspension system of shift shaft type OIS motor not only allows camera lens to move along focusing direction, also allow camera lens to do the small inclination (angle of inclination is generally in positive and negative 1.5 degree) of any direction with respect to a shaft fulcrum.Because rotating shaft is positioned at the position near camera lens bottom, therefore in the time that camera lens tilts, camera lens top is in fact with respect to the translation of imageing sensor left and right.Utilize this translation, just can compensate hand and tremble the flating bringing.Due to the existence of a fixing shaft fulcrum, the weight of motor motion parts has been shared by this fulcrum to a great extent, the angle of inclination of camera lens is subject to the impact of photography posture little of ignoring, camera lens is not subject to extraneous machinery yet and disturbs and swing, the inclination angle of camera lens is to stablize predictablely, is subject to the control of deflection current size completely.Therefore, the translational movement at camera lens top is also that the deflection current logical to motor is directly proportional.
The advantage of shift shaft type OIS motor is: structure and common AF motor approach, and the shortcoming of the above-mentioned parallel-moving type OIS motor of listing is substantially all the advantage of shift shaft type.In addition, shift shaft type OIS motor also has an exclusive advantage, can in cell-phone camera module, realize and move this special efficacy camera function that only has fever level slr camera to realize of axle photography (Tilt-shift Photography), greatly increase the playability of mobile phone photograph.In addition, for module manufacturer, because shift shaft type motor has the regulatory function of camera lens optical axis angle, therefore in module assembling, do not need high pixel module to assemble indispensable optical axis dynamic adjusting system (Auto Alignment System), this can be module factory and saves very large spending.The major defect of shift shaft type OIS motor is: opening after OIS function, camera lens can inevitably produce the inclination of optical axis in the time doing translation.In the time that angle of inclination is larger, can cause the corner part of image picture out of focus fuzzy.
