Description

Zoom shooting module

Technical field

The utility model relates to the camera technique field, is specifically related to a kind of zoom shooting module.

Background technology

The core image-forming block of digital camera has two kinds at present: a kind of is that widely used CCD(electric charge lotus root is closed) element; Another kind is a CMOS(CMOS (Complementary Metal Oxide Semiconductor) conductor) device.CCD: Charge Coupled Device (CCD) CCD image sensor (Charge Coupled Device), it uses a kind of semiconductor material of ISO to make, can be transformed into electric charge to light, convert digital signal to by the analog to digital converter chip, digital signal is preserved by the flash memory or the built-in hard disk card of camera inside after overcompression, thereby can give computing machine data transmission easily, and, revise image with imagination as required by means of the processing means of computing machine.CCD is made up of many sensitization units, is unit usually with the mega pixel.When the CCD surface was subjected to irradiate light, each sensitization unit can be reflected in electric charge on the assembly, and the signal that all sensitization units produced adds together, had just constituted a complete picture.CCD compares with traditional egative film, and CCD more approaches the working method of human eye to vision.Only, the retina of human eye is the awl cell of being answered by the rod cell of being responsible for the light intensity induction and color sense, the composition visual response of sharing out the work and help one another.The CCD process reaches the development in 35 years, and roughly shape and function mode are all finalized the design.The composition of CCD is mainly by grid, the light-collecting lens of a similar mosaic and fill up in lowermost electronic circuit matrix and formed.The capable at present company that produces CCD is respectively: SONY, Philps, Kodak, Matsushita, Fuji and Sharp most are Japanese manufacturers.CMOS: complementary matal-oxide semiconductor CMOS(Complementary Metal-Oxide Semiconductor) be all the same with CCD can be write down the semiconductor that light changes in digital camera.The manufacturing technology of CMOS and general computer chip do not have difference, mainly be to utilize silicon and these two kinds of semiconductors that element is made of germanium, make its band N(band – that on CMOS, coexisting) and P(band+) semiconductor of level, image be noted down and be interpreted to these two electric currents that complementary effect produced can by processed chip.Yet the shortcoming of CMOS is exactly to occur assorted point too easily, and this mainly is because early stage design makes CMOS when handling fast-changing image, because electric current changes too frequent and can produce overheated phenomenon.CCM:CCM is exactly the CMOS camera lens in fact, just the image quality of CCM than CMOS height a bit, induction speed is also very fast when taking pictures, but still be inferior to the CCD camera lens with photograph quality, also can feel out in actual photographed, the speed of finding a view be very fast, even if rapidly during the cell phone camera, screen can show the picture of grabbing of catching rapidly, and process is very smooth, does not almost have what delay.

Though the structure of photographing module of the prior art is compact, but in development and growth in the living standard along with technology, 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 the requirements such as image quality of further raising pixel quantity, increase optical zoom function and Geng Gao, existing photographing module has been difficult to satisfy these demands.
