Raws li ib qho ntawm cov tho kev ntawm cov thev naus laus zis thev naus laus zis, tus nqi- Cov lus qhia ua haujlwm nyob rau hauv cov txheej txheem kev lag luam tshwj xeeb thiab cov txheej txheem tsim kev tsim khoom. Nws cov kev ua kom muaj zog yog embodied nyob rau hauv cov tub ntxhais qhov ntev xws li teeb liab hloov dua siab txheem kev sib cav, nrov nrov tswj lub peev xwm, thiab cov duab zoo.
Hais txog nws txoj kev ua haujlwm tsim nyog thaij duab, CCD lub koob yees duab chot duab los ntawm cov cell ntawm cov duab xov xwm faib ua ke thiab hloov lawv cov cim. Cov nqi no yog cov kab hloov pauv los ntawm kab tsim tawm hauv ib qho "cov qauv",} Digital hloov pauv cov duab. Piv rau cov kev sib tw nyeem ntawv ntawm Cmos sensors, CCDs siv lub ntiaj teb shutter tsim los ntawm txhua lub pixels, zoo tshem tawm cov yob kaw hauv high {4} ceev cov suab scenes. Qhov no ua rau lawv haum tshwj xeeb rau cov ntawv thov yuav tsum tau ua kom nruj sij hawm, xws li kev lag luam kev lag luam thiab kev soj ntsuam science.
CCDs nthuav tawm qhov tseem ceeb hauv cov suab nrov supression. Lawv tus nqi hloov chaw ua ke siv cov txheej txheem tawg thiab}}}}}} {5}- suab sib piv. Txawm tias hauv qis - lub teeb ib puag ncig, CCDs tswj cov suab nrov qis, xa cov duab siab zoo nrog cov xim zoo nkauj nrog cov xim zoo nkauj. This makes them a preferred solution for low-light applications such as astrophotography and microscopy.
Cov duab zoo ib txwm muaj qhov tseem ceeb kev ntsuas ntawm CCD Technology. Los ntawm kev ua kom zoo cov qauv pixel thiab cov kab hluav taws xob, niaj hnub rov qab ua tiav 70 xyoo dhau los ua kom pom kev zoo tshaj li 900db, ua rau pom kev ntawm kev pom thiab tsaus ntuj. Hauv cov liaj teb tshwj xeeb xws li kev kuaj mob thiab cov chaw taws teeb ci, muab cov khoom siv hluav taws xob txias, muab kev txhawb nqa hluav taws xob txias, muab kev txhim khu kev txhawb nqa hluav taws xob txias, muab kev txhim khu kev txhawb nqa hluav taws xob kom khov
Txawm tias muaj kev sib tsoo tam sim no hauv CMOS thev naus laus zis hauv kev sib koom ua ke, CCS kev tshawb fawb xws li kev tshawb fawb high} kev tsim cov kev tsim thiab kev ua yeeb yam. Nrog rau kev nce qib txuas ntxiv ntawm rov qab-}}} cov koob yees duab txheej, CCD cov koob yees duab hauv cov ntawv siv thev naus laus zis hauv cov ntawv thov tshwj xeeb.
