Description

Split type camera head

Technical field

The present invention relates to camera technique field, be specifically related to a kind of split type camera head.

Background technology

The core image-forming block of digital camera has two kinds at present: 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, convert digital signal to by analog to digital converter chip, digital signal is preserved by flash memory or the built-in hard disk card of camera inside after overcompression, thereby can give computer transfer of data easily, and by means of the processing means of computer, revise image with imagination as required.CCD is made up of many sensitization units, conventionally taking mega pixel as unit.In the time that CCD surface is subject to light irradiation, each sensitization unit can be reflected in electric charge on assembly, and the signal that all sensitization units produce is added together, and has just formed a complete picture.CCD compares with traditional egative film, and CCD is the working method to vision closer to human eye.Only, the retina of human eye is by being responsible for the rod cell of luminous intensity induction and the cone cell that color sense is answered, the composition visual response of sharing out the work and help one another.CCD is through reaching the development of 35 years, and shape and function mode roughly are all shaped.The composition of CCD is mainly by grid, the light-collecting lens of a similar mosaic and be padded on lowermost electronic circuit matrix and formed.The capable company that produces CCD is respectively at present: SONY, Philps, Kodak, Matsushita, Fuji and Sharp are most Japanese manufacturers.CMOS: complementary matal-oxide semiconductor CMOS(Complementary Metal-Oxide Semiconductor) the be all semiconductor that in digital camera can record light variation the same as CCD.The manufacturing technology of CMOS and general computer chip do not have difference, mainly to utilize silicon and these two kinds of semiconductors that element is made of germanium, make its band N(band – electricity that coexisting on CMOS) and P(band+electricity) semiconductor of level, image be noted down and be interpreted to the electric current that these two complementary effects produce can by processed chip.But the shortcoming of CMOS is exactly the too easy assorted point that occurs, this is mainly because early stage design makes CMOS in the time 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, while taking pictures, respond to speed also very fast, but with photograph quality, be still inferior to CCD camera lens, in actual photographed, also can feel out, the speed of finding a view be very fast, even if when rapid cell phone camera, screen can show rapidly the catch picture of grabbing, and process is very smooth, almost there is no what delay.

Although the structure of photographing module of the prior art is compact, but in the development along with technology and growth in the living standard, people are more and more higher to the quality requirements of shooting, Here it is has proposed new challenge to photographing module, particularly be applied in digital camera (DC), when Digital Video (DV) or other association areas, special application demand has proposed new challenge to photographing module, mainly comprise further raising pixel quantity, increase the requirement such as image quality of optical zoom function and Geng Gao, 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 simple in structure, can optical zoom, the split type camera head of photographic effect and applied range.

For achieving the above object, technical scheme provided by the present invention is:

A kind of split type camera head, it comprises a microscope base, it also comprises a Zoom optic lens assembly and an imageing sensor, described microscope base be provided with one with the suitable cavity of 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 microscope base bottom, and this opening is sealed, described Zoom optic lens assembly is inserted described cavity, and aligns mutually with described imageing sensor.

Described Zoom optic lens assembly comprises three Zoom Lens camera lenses and a lens control assembly, described three Zoom Lens camera lenses are inserted described cavity, described lens control assembly is arranged on microscope base one side, and can drive described three Zoom Lens camera lenses to make zoom, focus operation.Replace traditional tight shot with three Zoom Lens camera lenses, can effectively 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, applicable brightness range is mentioned 5 times.

Described imageing sensor is the CCM transducer of nine mega pixels.Replace traditional VGA transducer with the CCM transducer of nine mega pixels, can make valid pixel quantity improve 3 ~ 5 times and 4 times of left and right of image analytic degree raising, so that meticulousr picture quality to be provided, simultaneously, the view data output of this CCM transducer is used rgb format, makes the more simple general-purpose of design of back-end processing system.

The interfaces of connecting wires of described lens control assembly is positioned at bottom one side 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, have greatly simplified the manufacturing process of camera module, can effectively improve volume production efficiency 30%, reduce costs 7%; But also reduced the design difficulty of back-end system, and expand the scope of application of back-end system, make the design of build rear end, unit become possibility.

Beneficial effect of the present invention is: the present invention is simple in structure, be provided with three Zoom Lens, can effectively 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, valid pixel quantity and image analytic degree are greatly improved, ensure picture quality, in addition, interface adopts split-type structural design, make each assembly separate, not only greatly simplify manufacturing process, enhance productivity, reduce costs, also further expand its scope of application, can meet the application demand of different DC/DV products, application prospect is extensive, be beneficial to popularization.
