Description
Technical field
The utility model relates to a kind of portable electric device with camera module, particularly relates to a kind of portable electric device with the camera module of vibration compensation function.
Background technology
Along with the progress of digital technology and the prosperity of electronic industry, image stabilization technology (Image Stabilization Technology) is not only and is applied to digital code camera, also other digital devices are popularly applied in rapidly, as: digital camera, the mobile phone etc. with camera function, in recent years, in view of digital camera device uses the expansion in field, except possessing the performance such as auto-focusing and many multiplying powers zoom, the necessity of image vibration compensation function (i.e. image stabilization technology) day by day manifests.When photographer's hand-held digital camera or the mobile phone with camera function are taken, if operation object that is unstable or that intend carrying out taking is moving object, the problem of image blur often can be caused.The reason of this phenomenon is caused to be: when light source converts digital electronic signal imaging to by the CCD/CMOS image sensor of digital camera device, opto-electronic conversion needs certain processing procedure, in the process, if there are vibrations in camera or shooting object moves and causes light abnormal displacements, captured image just can be very fuzzy, and the user of digital camera device takes with hand-held mostly, rocking of picture is caused unavoidably because of the gripping shakiness of user, so, the image vibration compensation function (i.e. image stabilization technology) of digital camera device is a large important key.
The image stabilization technology of digital camera device is divided into optical profile type anti-hand shake technology and electronic type anti-hand shake technology two kinds substantially now.1994, Nikon (Nikon) company released the digital camera that first item has shock mitigation system (Vibration Reduction) technology.Nineteen ninety-five, Canon (Canon) company releases the digital camera that global first item has image stabilization device (Image Stabilizer) camera lens.
The representative firm of optical profile type anti-hand shake technology comprises: Canon (Canon), Nikon (Nikon) and Panasonic (Panasonic).Optical profile type anti-hand shake technology utilizes the gyroscope be arranged in camera lens to detect minute movement, and this movable signal is reached microprocessor, calculate the required displacement compensated immediately, then by image stabilization device lens set, compensated according to the vibrations direction of camera lens and displacement, and then overcome the situation because of image fog caused by camera shake.Vertical the vibrations compensating camera body by the movement of image stabilization device lens set, and reach the shooting image quality of better image, the compensate for displacement amount that only the image stabilization device of optical profile type anti-hand shake technology calculates still is confined to the vibrations of the aperture time in certain limit, therefore limited efficiency, and an image stabilization device lens set must be set separately in camera lens, the volume of the cost raising and camera lens that cause digital camera is increased.
The representativeness of electronic type anti-hand shake technology is as the antidetonation program (Anti-Vibration Program) of Olympus (Olympus), it is the actual conditions according to shooting, by setting such as adjustment shutter speed and ISO light sensitivity etc., alleviate photographer's handheld camera and shake the impact caused.Separately, the best shooting selector switch (Best-Shot Selector that Nikon (Nikon) digital camera adopts, BSS) one of electronic type anti-hand shake technology is also belonged to, best shooting selector switch (BSS) is that a kind of software that utilizes is to compensate the function of image fog, that is when starting described function, digital camera can take about 10 photos continuously, then the photo of a sharpness the highest (namely details shooting is best) is therefrom selected, its cardinal principle is comparatively large by the photo capacity of imaging clearly and sharpness is better, relatively, the photo capacity of vibrations is less and sharpness is poor.Relative to optical profile type anti-hand shake technology, though be antidetonation program or best shooting selector switch all relatively reduce the cost of digital camera, only electronic type anti-hand shake technology is not so good as optical profile type anti-hand shake technology to the effect of vibration compensation, and easily produce image incidental information and reduce image quality, also must the larger image sensor of useful area support, in addition, it is just won in several photos of just shooting continuously and selects a higher photo of sharpness on the whole, but not comprehensively carry out adjustment of image, so vibration compensation effect is also limited to some extent.
In sum, optical profile type anti-hand shake technology to utilize in lens group with gyroscope to drive corresponding privileged sites eyeglass, adjusts position and the angle of described eyeglass, carry out image compensation because of vibrations; And electronic type anti-hand shake technology utilizes the image sensor of large effective area, regulates shutter speed and ISO light sensitivity etc. to compensate vibrations.Only optical profile type anti-hand shake technology makes the cost raising of digital camera and the volume of camera lens increase because arranging an optical compensation lens set separately, and though electronic type anti-hand shake technology must by optical compensation lens device, but because of under the shooting environmental that light condition is good not to the utmost, shutter speed and ISO light sensitivity is regulated to cause image quality to reduce.
