Charge lotus root adds up to CCD of sensor of image of parts of an apparatus (ChargeCoupledDevice) , it uses the semiconductor material of a kind of high speed to be made, can transform the light into charge, through modulus converter chip changeover becomes digital signal, after digital signal course is compressed, shine in-housely by camera fast memory or inside card of buy hard disk is saved, can transmit data easy to doly to the computer consequently, and the processing of have the aid of at the computer method, will alter image according to need and be being envisaged. CCD is comprised by a lot of sensitive units, normally with 1 million it is an unit like element. Get when CCD surface when radial illuminate, every sensitive unit can reflect charge on package, the signal that all sensitive unit place generate adds in, made a complete appearance. CCD and traditional negative photograph are compared, CCD is more adjacent be opposite at person eye working way of the vision. Just, the retina of person eye is by the lever of induction of responsible luminous intensity the cell is mixed the awl cell of colour induction, cooperate with division of labour compositive vision induction. CCD passes the development that is as long as 35 years, roughly appearance and run means to had finalized the design. The composition of CCD basically is by the reseau of a similar mosaic, condenser piece and mat comprise at place of matrix of lowermost electron circuitry. At present the company of capable production CCD is respectively: SONY, Philps, Kodak, Matsushita, Fuji and Sharp, it is Japanese manufacturer largely. CMOS of semiconductor of metal of complementary sex oxidation (Complementarymetal-OxideSemiconductor) be the same as the semiconductor that changes to the light can be recorded in digital camera with CCD. The production technology of CMOS and difference of it doesn't matter of general computer chip, basically be to use silicon and germanium the semiconductor of make it of place of these two kinds of elements, make its are coexisting on CMOS take N (the report that take –) with P (belt + report) the semiconductor of class, the electricity that place of these two complementary effect produces can be reconciled to be read by processing chip record video. However, the defect of CMOS appears too easily namely miscellaneous dot, because inchoate design makes CMOS is when those who handle rapid change is video,this basically is, because electric current changes too frequent and the phenomenon that can produce overheat.
