Description
Technical field
The present invention relates to a kind of camera model, linear and uniform active force can produce more particularly to one kind and can be into one
Step reduces the camera model of volume.
Background technique
Due to the progress of science and technology, so that the volume of digital still camera increasingly reduces, and numerous compact electronic devices at present, such as hand
Machine nearly all builds the function of numerical digit camera shooting, these are all attributed to the fact that the microminiaturization of optical imaging apparatus.And it is used now
It is voice coil motor (VCM) that micro-lens, which are commonly used most, carries mirror using the combination of coil, magnet and elastic slice
Head is moved forward and backward in shooting optical axis direction, to reach the function of auto-focusing or zoom, and for camera shooting quality and function
Requirement be also gradually increased.Such as: the functions such as ten million pixel, the shake of anti-hand, to separate the difference of higher end camera and low order.
In the optical system that one is made of optical imaging apparatus and image compensation module, such as camera or photography
The optical system of machine etc., shake when often can be because of external force factor or handheld camera or video camera, and cause the shake of light path
It is dynamic to deviate and make the imaging in image compensation module unstable, and then cause taken image blur unclear.It is most common
Settling mode, be exactly to it is such because vibration caused by image blur phenomenon provide compensation mechanism, to make optical imaging apparatus
The image definition captured, and such compensation mechanism can be numerical digit compensation mechanism or optical compensation mechanism.Wherein institute
The numerical digit compensation mechanism of meaning is exactly analyzed and is located through software to the digital image data that image compensation module captures
Reason, to obtain relatively clear digital image, such mode is also commonly known as the shockproof mechanism of numerical digit.As for optical compensation machine
System is then usually vibration-compensated device to be arranged on optical imaging apparatus or image compensation module, and such mode is also normal
The referred to as shockproof mechanism of optics.
General traditional shockproof mechanism of optics, the flexible portion material constituted using the metal steel wire of straight line strip is by optics
Device for image is carried on above the circuit substrate with Image Sensor.This optical imaging apparatus contains camera lens and camera lens is protected
Hold portion.When optical imaging apparatus is varifocal or focusing lens group, the camera lens in optical imaging apparatus can be opposite
The movement of a direction is carried out in camera lens maintaining part.When there is vibration to occur, optical imaging apparatus and circuit substrate are between the two
Relative displacement can be generated.At this point, can be by optical imaging apparatus and electricity through relative displacement sensor and position mobile detection device
The displacement of X-axis and Y-axis between base board is transmitted to shockproof control unit, controls mobile driving portion according to its displacement and drives optics shadow
As device makees corresponding compensation campaign with circuit substrate, with the fuzzy image for preventing Image Sensor from generating by vibration.However,
Such structure can directly increase the size of overall volume because of the configuration mode of shockproof control unit and mobile driving portion, make
The surface that whole X-axis to Y-axis is parallel to optical imaging apparatus can not further reduce area.
It can be seen from the above, the shockproof mechanism of the optics being currently known, involves complicated or large volume heavy mechanism mostly
Or element, therefore in the presence of structure is complicated, assembles the shortcomings that difficulty, higher cost or volume can not further reduce, therefore it is related
Dealer is seeking its solution.
