Description
Technical field
The present invention relates to camera module field, be specifically related to a kind of digital camera camera module.
Background technology
The core image-forming block of current digital camera has two kinds: one is that widely used CCD(electric charge lotus root is closed) element; Another kind is CMOS(CMOS (Complementary Metal Oxide Semiconductor) conductor) device.CCD: CCD CCD image sensor (Charge Coupled Device), it uses a kind of semi-conducting material of ISO to make, light can be transformed into electric charge, digital signal is converted to by analog to digital converter chip, digital signal is preserved by the flash memory of camera internal or built-in hard disk card after overcompression, thus easily data can be transferred to computer, and by means of the process means of computer, revise image with imagination as required.CCD is made up of, usually in units of mega pixel many photosensitive units.When CCD surface be subject to light irradiate time, electric charge can be reflected on assembly by each photosensitive unit, and the signal that all photosensitive units produce is added together, and just constitutes a complete picture.CCD compares with traditional egative film, and CCD is closer to the working method of human eye to vision.Only, the retina of human eye is the cone cell that the rod cell responded to by responsible luminous intensity and color sense are answered, composition visual response of sharing out the work and help one another.The development of CCD through reaching 35 years, shape roughly and function mode are all shaped.The composition of CCD mainly by a similar mosaic grid, light-collecting lens and be padded on lowermost electronic circuit matrix and form.The company having the ability to produce CCD is at present respectively: SONY, Philps, Kodak, Matsushita, Fuji and Sharp are most Japanese manufacturers.CMOS: Complimentary Metal-Oxide semiconductor CMOS (Complementary Metal-Oxide Semiconductor) is the same with CCD is all the semiconductor that can record light change in digital camera.Manufacturing technology and the general computer chip of CMOS do not have difference, mainly utilize the semiconductor that silicon and this two kinds of elements of germanium are made, make it on CMOS, co-exist band N(and be with – electricity) and P(band+electricity) semiconductor of level, the electric current that these two complementary effects the produce chip that can be processed is noted down and is interpreted to image.But the shortcoming of CMOS is exactly the assorted point of too easy appearance, and this is mainly because early stage design makes CMOS when processing fast-changing image, because curent change too frequently can produce overheated phenomenon.CCM:CCM is exactly CMOS camera lens in fact, just the image quality of CCM than CMOS height a bit, speed is responded to also very fast when taking pictures, but with photograph quality, be still inferior to CCD camera lens, also can feel out in actual photographed, find a view speed quickly, even if rapidly during cell phone camera, screen can show rapidly catch the picture of grabbing, process is very smooth, does not almost have anything to postpone.
Although the structure of photographing module of the prior art is compact, but along with the development of technology and growth in the living standard, the quality requirements of people to shooting is more and more higher, Here it is proposes new challenge to photographing module, particularly be applied in digital camera (DC), when Digital Video (DV) or other association areas, special application demand proposes new challenge to photographing module, mainly comprise the requirements such as the image quality improving pixel quantity, increase optical zoom function and Geng Gao further, existing photographing module has been difficult to meet these demands.
Summary of the invention
The object of the invention is to, for above-mentioned deficiency, provide a kind of structure simple, can optical zoom, photographic effect and the digital camera camera module of applied range.
For achieving the above object, technical scheme provided by the present invention is:
A kind of digital camera camera module, it comprises a microscope base, it also comprises a Zoom optic lens assembly and an imageing sensor, described microscope base is provided with a cavity suitable with the appearance profile of described Zoom optic lens assembly, this cavity bottom is provided with an opening, and the position of the corresponding described opening of described imageing sensor is fixed on bottom microscope base, and is sealed by this opening, described cavity inserted by described Zoom optic lens assembly, and aligns mutually with described imageing sensor.
Described Zoom optic lens assembly comprises three Zoom Lens camera lenses and a lens control assembly, described cavity inserted by described three Zoom Lens camera lenses, described lens control assembly is arranged on microscope base side, and described three Zoom Lens camera lenses can be driven to make zoom, focus operation.Replace traditional tight shot with three Zoom Lens camera lenses, effectively can improve the overall optical property of camera module, its scope of application and reference object are significantly expanded, as effective shooting distance improves 3 ~ 4 times, the brightness range be suitable for mentions 5 times.
Described imageing sensor is the CCM transducer of nine mega pixels.Traditional VGA transducer is replaced with the CCM transducer of nine mega pixels, valid pixel quantity can be made to improve 3 ~ 5 times and to improve about 4 times with image analytic degree, to provide meticulousr picture quality, simultaneously, the view data of this CCM transducer exports and uses rgb format, makes the design more simple general-purpose of back-end processing system.
The interfaces of connecting wires of described lens control assembly is positioned at the side, bottom of described microscope base, and the interfaces of connecting wires of described imageing sensor is positioned at the bottom opposite side of described microscope base.The interface of lens control assembly and the interface of imageing sensor adopt split-type structural design, make lens control assembly, imageing sensor independent separately, enormously simplify the manufacturing process of camera module, can effectively improve volume production efficiency 30%, reduce costs 7%; But also reduce the design difficulty of back-end system, expand the scope of application of back-end system, made the design of unit build rear end become possibility.
Beneficial effect of the present invention is: structure of the present invention is simple, be provided with three Zoom Lens, effectively can improve the overall optical property of camera module, its the scope of application and reference object are significantly expanded, and adopt the CCM transducer of high pixel, substantially increase valid pixel quantity and image analytic degree, ensure picture quality, in addition, interface adopts split-type structural design, make each assembly separate, not only enormously simplify manufacturing process, enhance productivity, reduce costs, also expand its scope of application further, the application demand of different DC/DV products can be met, application prospect is extensive, be beneficial to popularization.
Below in conjunction with accompanying drawing and embodiment, the present invention is further described.
