Description
Technical field
The present invention relates to the ultraminiature camera module, relate in particular to the blocking device that comprises make-up machinery aperture and shutter, has certain displacement that can keep above-mentioned mechanical aperture and shutter, not only can improve image quality, also can utilize electromagnetic force to realize, can obviously reduce the volume of total system, can be applicable to need to install the ultraminiature camera module on the plurality of devices such as portable terminal computer of ultraminiature camera module.
Background technology
Recently, along with the development of the communication technology and digital information processing, the portable terminal technology that integrates multiple functions such as information processing, calculating, communication and image information output input obtains new progress.
With PDA with digital camera and communication function and the mobile phone with digital camera and PDA function is example, along with the development of digital camera technology and information storage capability, assemble high-level digital camera module (digital camera module) and will popularize gradually.
The development of various technology based on this, be installed in and used mega pixel (mega pixel) level imageing sensor (image sensor) in the digital camera module on the portable terminal computer, be accompanied by the use of optical zoom (optical zoom), automatic focusing (Auto focus) function, the importance of mechanical shutter (mechanicalshutter) and mechanical aperture (mechanical iris) function is more outstanding.
The scanning motion mode that above-mentioned CCD adopts has staggered scanning (interlaced scan) and (the progressive scan) two kinds that line by line scan.
Above-mentioned interlacing formula is as the existing video employed mode of CCD, and portrait will be through twice scanning.If scanning is at twice arrived before the scanning for the second time after single pass is finished, also have light and continue to enter, cause image frame with low quality.
Therefore, in order to obtain the image of high image quality, must consider to use mechanical shutter in the step of twice scanning, to block the process of light source fully.
Different therewith, become period of main flow at 350,000 Pixel-level digital cameras, employing be the progressive scan mode of the whole pixels of one-off scanning.The advantage of this mode is the error that does not produce because of the time interval, so can be may command with electronic shutter only without mechanical shutter.
Yet in the digital camera more than existing 3,000,000 pixels, can obtain more light quantities, interlace mode that image quality is vivider under the CCD situation that has adopted once more in identical size.
In this case, as mentioned above, only can not obtain the image quality expected, so actively attempt to adopt the technical research of mechanical shutter with electronic shutter.
Above-mentioned mechanical shutter is blinked as the people, in the moment of taking a picture, in fact closes and intercepts curtain, shelters from unnecessary light, has the function that image quality is improved a level.Therefore when under strong reflected light such as the electric light or the sun, taking pictures, can eliminate stain (Smear) phenomenon of the vertical lines that occur on the picture, obtain the distincter photo of image quality with software or hardware.
When adopting above-mentioned mechanical aperture, can adjust the light quantity and the mechanical shutter that enter and utilize the suitable value of stretching out to obtain distinct image quality together.Also can adjust the depth of field, the ultraminiature camera module also can be the same with ordinary camera, shoots the photo of the various atmosphere of the subjective thought of reflection photographer.
In addition, the function that the aberration that adopts the camera of mechanical iris diaphragm structure to have to reduce the difference between the light of coming in because of the light of coming in by the centre of camera lens and by camera lens periphery position to produce diminishes, so can block the light of coming in by the mode of turning aperture down from the peripheral position of camera lens, the light at position, optical center is mainly used in image, obtains the photo that aberration is little, image quality is distinct.
Therefore, mechanical aperture is being developed to the accessory into the mega pixel cameras indispensability of pursuing high image quality.
For the function with mechanical shutter and aperture is applied on the microminiature digital camera module, it is little to need relative volume, can satisfy the driver of performances such as fast reserve, low energy consumption, big displacement.
Particularly, require driver to want to adapt to the increase of required displacement along with the increase of picture size.And the common electrical magnetic driven device of prior art (magnetic actuator) needs a large amount of accessories, thus price with big or small aspect have limitation, the displacement increase is limited; Can only utilize open and close to drive, so have weak point aspect realization and the existing mechanical aperture identical functions.
In addition, the driver that is rotated motion with step motor (stepping motor) etc. comes mobile movable part, because use gear in the process that transmits power, so accessory is many and complex structure.
In addition, have that response speed is slow, gear part produces shortcomings such as friction and noise.When mechanical shutter that adopts aforesaid way and aperture driver, because complex structure be difficult to make cheap driver, and aspect miniaturization, size is restricted.
Summary of the invention
The present invention proposes for addressing the above problem just.The objective of the invention is to: the ultraminiature camera module that a kind of make-up machinery aperture and shutter are provided, wherein mechanical shutter and aperture use VCM (the Voice Coil Motor: the Linear actuator of formula voice coil motor) of trickle precision processing technology or micromachining fabrication techniques, improve image quality by above-mentioned mechanical shutter and aperture are installed, can be made into the camera module of various structures according to the collocation method of shutter and aperture and optical module.
