Description

A kind of high-performance and reliable miniature stabilization holder
Technical field
The utility model relates to stabilization holder technical field more particularly to a kind of high-performance and reliable miniature stabilization clouds Platform.
Background technique
The small-sized mobile devices with focusing wide angle (visual angle is more than 80 degree) shooting function are very universal in recent years, using model Also constantly extension is enclosed, including Zhi Yan Jing ﹑ Ping plate Ji Suan Ji ﹑ and can take photo by plane.In said device, wide comprising an at least fixed-focus Angle camera mould group (Fixed-focus wide-angle camera module).Therefore, the market of the mould group is very huge, increases Length also raises up steadily.When taking pictures and clapping film, described device takes the photo come and film is most likely subject to Extraneous vibrations and Occur fuzzy or shake, influences photo and film quality.It is fiercer when vibrating, or in low smooth situation, this problem can be more Seriously.
To solve the above-mentioned problems, many existing stabilization technologies are had already appeared in the market.The existing mainstream technology passes through Reading vibrating sensor (such as: gyroscope and acceleration sensor), vibrational waveform and required offset angle are calculated, electricity is passed through The image blur and shaking that sub- ﹑ Guang ﹑ or mechanical means compensation are made by vibration, up to the effect for causing improvement image quality.
The prior art can be divided into four classes, including electron image stabilizer (Electronic by method for compensating vibration Image stabilizer, EIS) ﹑ optical image stabilizer (Optical Image stabilizer, OIS) ﹑ stabilization holder (Gimbal Stabilizer, GS) ﹑ and miniature stabilization holder (Micro Gimbal Stabilizer, MGS).EIS ﹑ OIS ﹑ And MGS has their own advantages and disadvantage.
EIS is by electronic method, up to cause anti-shake effect.When shooting, EIS can be adjusted with the vibrational waveform according to calculating The position of each frame image is offset the image being made by vibration and is shaken.Since EIS does not need additional actuator, so EIS Major advantage be it is at low cost, close to be not necessarily to additional weight and volume.
OIS be by optics and mechanical means, using the mobile optical component of actuator (it is can be magazine a piece of, one Group or all eyeglasses), up to causing occur relative motion between optical component and imaging sensor, change optical path (Optical Path) And at the position image circle (Image Circle), offsets the image being made by vibration and shake.Since OIS is to shoot each frame image In constantly make optical compensation, therefore shake when can offset each frame image exposure can be up to causing image matter more preferably than EIS Element.
GS (referenced patent: CN103513492A ﹑ CN104903790A ﹑ EP3086451A1 ﹑ and US20090257741A1) be the entire camera mould group comprising eyeglass and imaging sensor of driving by mechanical means, make and Direction of vibration on the contrary, but the close movement of amplitude, offset the shaking being made by vibration.In anti-shaking process, due to optical component There is no relative motion between imaging sensor, so image quality and anti-shake effect are not in decline in image edge, also Part optics resolution and imaging sensor part resolution because of stabilization Xi domestic animal camera lens are not needed.Therefore, the stabilization of GS Effect and image quality ratio EIS and OIS are advantageous, and the advantage is more prominent in wide angle camera mould group.
The stabilization principle and GS of MGS (referenced patent: 208399865U) is close, be all by drive entirely comprising eyeglass and The camera mould group of imaging sensor, up to the effect for causing stabilization.MGS is designed using special elastic slice and flexible circuit board, Da Zhijie Save space.In order to be further simplified design and save space, be not provided in MGS displacement sensor (such as: Hall effect sensing Device), induction movable member (such as: coil, camera lens, lens mount and image sensor) relative to not dynamic component (such as: magnetite and Shell) deflection or displacement.MGS, using open-loop control method, deflects camera lens up to cause anti-shake effect in anti-shaking process.
The main Que Dian Yes of EIS can not compensate the shaking of the image in each frame, this is because EIS is by adjusting each frame The position of image is offset the image being made by vibration and is shaken.So the image that EIS is shot after opening can be easier to occur because of shadow As what shaking was made into obscures.
Another EIS is the disadvantage is that the Xi domestic animal resolution of imaging sensor.When EIS is opened, imaging sensor or image Processor needs to cut out suitable image by calculating vibrational waveform, as final image.In tailoring process, resolution can under Drop, the final image can resolution more maximum than imaging sensor it is low.Therefore, EIS can the maximum solution of Xi domestic animal imaging sensor Picture degree reduces image quality.
Opposite GS, the major defect of OIS is the part optics resolution of Xi domestic animal camera lens.During OIS, imaging coil is being schemed As the position on sensor can constantly change.Exceed imaging sensor during OIS in order to avoid exceeding at image circle, at image circle It must expand because of OIS, but this can waste the due resolution of camera lens.On the other hand, during OIS, treat as image circle Position it is more inclined when, can be closer to imaging sensor at image circle edge.Since most camera lens is in edge blurry degree and distortion Degree is all more serious than center, therefore the image resolution of general OIS and anti-shake effect, all not as good as GS, this problem is in wide angle camera mould group In become apparent from.
Although image quality and anti-shake effect the ratio OIS and EIS of GS has a clear superiority, GS needs can drive entire phase The actuator of machine mould group.Since the weight and size of camera mould group are more more than camera lens, the Cheng of GS actuator this ﹑ Chong Liang ﹑ body Long-pending and power consumption is usually more much higher than OIS actuator, suitable for application in small-sized mobile devices, or can reduce mobile device battery Cruise duration.
On the other hand, the GS technology (referenced patent: CN103513492A ﹑ CN104903790A ﹑ EP3086451A1 ﹑ of mainstream And US20090257741A1) ball bearing or other contact points with frictional force are used, as fixed and movable member Between mechanical support structure.Due to being nonlinear pass between the frictional force of the support construction and the speed of movable member System, therefore the support construction increases nonlinear frictional force, the frictional force can influence anti-shake effect.Especially work as vibration When dynamic finer and frequency is higher, influencing can be more obvious, and anti-shake effect may be not good enough.In addition, most GS technology is adopted With closed-loop control, the control circuit of GS needs additional power consumption to stablize stabilization system.It is described when Oscillation Amplitude and excessively high frequency Output voltage needed for control circuit or electric current may exceed the limit of control circuit, and circuit overheat or anti-shake effect is caused to owe It is good.
Because MGS is not not in the shortcomings that frictional force is brought using the contact point for having frictional force.But It is, since MGS uses elastic slice and open-loop control system, when MGS is total to by intense vibration or vibration frequency close to the system The problem of when vibration frequency, being easy to appear resonant conditions, causing video blur and shake.If fruit this situation occurs for a long time, more may be used MGS internal part can be destroyed, leads to occur dust or MGS on imaging sensor to can not work normally, influences the reliable of MGS Property.In addition, the image sensor can not be rigid because the image sensor needs in MGS deflect in anti-shaking process It is fixed in motionless structure.The heat that image sensor issues can only pass through far distance by thermal radiation, or by heat transfer Get to the shell of MGS.Since the efficiency of these methods is all very low, causes the image sensor temperature in MGS higher, cause Image noise is more.This problem also results in the image sensor in MGS and can not work in the environment of higher temperatures, limits MGS Highest ambient operating temperature, reduce the reliability of MGS.
