Description
[technical field]
The utility model is about a kind of camera module, especially can alleviate the camera module that user's hand shakes or other vibrations influence image quality about a kind of.
[background technology]
Along with Development of Multimedia Technology, digital camera, video camera and the portable electronic equipment with camera function more and more are consumers in general's favor, for ease of carrying, the portable electronic equipment that people wish digital camera, video camera and have a camera function develops to miniaturization.But small digital cameras, video camera and have that the volume of portable electronic equipment of camera function is little, fuselage is light, very easily causes the fuselage shake when pressing shutter make the image fog of taking.
Address the above problem and promptly reduce fuselage shake and cause the method for the image fog of shooting to have two kinds, the first is fixed camera or add stable holding mechanism, reduces the probability of happening of fuselage shake.As select to use tripod, but because tripod is relatively heavier, carry and place equal inconvenience, loading and unloading also bother with adjustment, and being not suitable for fast moving takes, people with digital camera, video camera and portable electronic equipment with camera function to the miniaturization development to be convenient for carrying, under the normal condition, the user can't also carry tripod, do not take pictures and there is tripod to hand, just can't guarantee still to obtain imaging clearly when shutter is slow, promptly can not capture excellent image at any time, therefore most users can't select to use tripod.Also have, a hand-held band that is disclosed for No. 91232728 as Chinese patent CN relies on the electronic shutter camera handle exactly, it comprises handle, carriage, camera installing mechanism and electronic shutter control gear, camera is fixed on this handle, just can carry out high-quality shooting activity by means of carriage, and the control of electronic shutter is positioned at handle forefinger position, and is easy to use and reliable.This handle is held the rifle gunnery according to the soldier, makes camera have advantages of higher stability, can reduce the influence of vibrations to taking.But it has only reduced the generation of camera vibrations, and can't reduce to shake the influence that the filmed image quality is produced, and can't reach the purpose of the higher image of shooting quality.
It is to adopt anti-shake technology that the shake of minimizing fuselage causes the another kind of method of the image fog of shooting, and anti-shake technology commonly used at present mainly contains three kinds.
First kind is with the anti-shake technology of optics headed by Canon, the Panasonic, and it utilizes the direction of inductor induction shake by relying on magnetic force parcel suspension camera lens, bears compensation according to the direction of motion and the displacement of camera lens then, thereby produces clear sharp keen photo.Wherein, the anti-shake technology IS of the optics of Canon (ImageStabilization, image stabilizator) full name is a phase shift type optical image stabilization technology, and it relies on magnetic force parcel suspension camera lens, thus effectively overcome because of camera vibration produce image blurring.Gyroscope in its camera lens can detect small motion, bears compensation according to the direction of motion and the displacement of camera lens then, thereby produces clear sharp keen photo.Anti-shake OIS (the Optical Image Stabilization that is called of the optics of Panasonic, the optical image stabilizator), there be play the same tune on different musical instruments wonderful in its principle and Canon, also be to rely on magnetic force parcel suspension camera lens to realize anti-vibration functions, this technology has adopted motion sensor, can find out when taking slight hand and tremble and can carry out continuous compensation fast and cut down shake and disturb.
Second kind is the electronic flutter-proof braking technique, and its adjustment by the digital camera inner parameter reduces shake to be influenced for imaging, and normally the mode by computed in software remedies the influence that shake brings when data sampling and image synthesize.What representative was comparatively arranged is the BSS of Nikon and the electronic flutter-proof of Olympus.The BSS full name of Nikon is the best selector switch of taking, and when this function was opened, camera can be taken maximum 10 photos continuously, and comparison film compares then, and the photo of sharpening degree the highest (details is taken best) will be than noting.Its main principle is exactly, and the general capacity of imaging clear photograph is bigger, and acutance is better, and the photo capacity of shake is less, and acutance is relatively poor.By continuous shooting, can reduce the camera shake when pressing shutter.The electronic flutter-proof of Olympus, when under low light photograph condition, taking, the phase chance promotes the ISO light sensitivity automatically, carry out that best shutter speed is selected automatically and flash of light triggers and is provided with, to prevent that because of camera shake causes image fog, its practical work process is not done any protection and compensation to the shake of camera.
The third is the anti-shake technology AS of fuselage (Anti Shake, an against shock), and it is the technology of Konica Minolta company original creation.Utilize the floating element structure different with traditional anti-shock system, its principle and Canon, the anti-shake technology of the optics of Panasonic is opposite.It is to utilize floating of CCD to realize, by the vibrations of sensor sensing camera, is floated by the CCD of fuselage interior then and obtains imaging clearly.
A kind of existing digital camera that adopts anti-shake technology such as No. the 5172276th, United States Patent (USP) announcement, is furnished with the vibrations corrective lens in its camera lens, this corrective lens can move in perpendicular to the plane of camera lens optical axis, to avoid vibration because of hand shake causing camera image, this camera inside is provided with the shock momentum that a hand shock detection device that is made of angular-rate sensor or similar device is used for detection camera, simultaneously in perpendicular to the plane of camera lens optical axis, drive this vibrations corrective lens, thereby reduce the image shake with value corresponding to this shock momentum.
The above-mentioned fixing camera such as tripod that need to adopt, usually inconvenience carry and image quality undesirable.And adopting the camera of anti-shake technology, it all need be provided with various inductors in camera inside, measures the jitter parameter of camera by inductor, and is moved to compensate by adjusting mechanism control associated components according to the jitter parameter that records.Its structure is various, assembling is complicated, it is used for mm professional camera special and still can, general portable electronic equipment wants cube little, in light weight, mobile phone camera module particularly, adopt above-mentioned anti-shake technology will increase the inner structure of mobile phone, volume and weight, and the more installation of assembly is complicated, obviously inapplicable.
In view of this, provide a kind of and can alleviate user's hand shake or other vibrations are real in necessary to the camera module of image quality influence.
[utility model content]
The purpose of this utility model is to provide a kind of can alleviate the camera module that user's hand shakes or other vibrations influence image quality.
The utility model camera module comprises at least one lens, a lens barrel, a substrate, an image sensor, a bearing and a plurality of elastic damping module.This lens barrel is roughly cylindric, in order to the above-mentioned at least one lens of fixing; This substrate is fixed in an end of above-mentioned lens barrel; This image sensor be arranged on the substrate be immobilizated in lens barrel in the relative position of lens; This bearing has a cavity so that the ccontaining above-mentioned lens barrel of small part; These a plurality of elastic damping modules are distributed between above-mentioned lens barrel and the bearing, make lens barrel closely be suspended in bearing.
Compared with prior art, this camera module is by a plurality of elastic damping module absorbing vibrations, thereby reduce the image shake that causes because of the camera vibrations, and the elastic damping module has simple in structure, easy to assembly, low cost and other advantages, improve the shooting effect of camera module when can keep the light minor structure of camera module, and cost increases limited.
