  • Qhov zoo thiab qhov tsis zoo ntawm ccd thiab cmos

    Tam sim no, nyob rau hauv lub tshav pob ntawm lub zeem muag hmo ntuj, CCD interlaced scanning yog siv rau imaging.CMOS yog qhov kev ntsuas siab tshaj plaws, yog li cov duab ntawm CMOS zoo dua li ntawm CCD.Tam sim no, CMOS tau pib hloov CCD hauv kev pom kev hmo ntuj.

    CCD thiab CMOS sensors yog ob feem ntau siv cov duab sensors tam sim no.Ob leeg siv photodiodes rau photoelectric hloov dua siab tshiab los hloov cov duab rau hauv cov ntaub ntawv digital.Qhov sib txawv tseem ceeb yog txoj hauv kev uas cov ntaub ntawv digital raug xa mus.Feem ntau hais lus, cov duab zoo ntawm CCD chips siv hauv cov koob yees duab digital zoo tib yam yog qhov zoo dua.

    Qhov zoo thiab qhov tsis zoo ntawm CCD: kev siv hluav taws xob tsawg, tsis muaj hluav taws xob ua haujlwm;poob siab thiab kev co kuj, kev ua haujlwm ruaj khov, lub neej ntev;siab rhiab heev, tsis tshua muaj suab nrov, loj dynamic ntau yam;ceev teb ceev, nws tus kheej-scanning muaj nuj nqi, me me duab distortion, tsis muaj residual duab;daim ntawv thov VLSI txheej txheem thev naus laus zis ntau lawm, siab pixel kev koom ua ke, qhov loj me, tus nqi qis ntawm kev lag luam ntau lawm.

    CMOS Qhov Zoo thiab Qhov Tsis Zoo: Qhov rhiab heev, suab nrov thiab kev ua haujlwm tsaus nti tam sim no ntawm lub sensor yog qis dua li ntawm CCD sensors.CMOS sensors tsis tas yuav siv lub moos sab nraud ntawm lub tshuab hluav taws xob los tsim cov hluav taws xob thiab cov nthwv dej kom txav mus los ntawm lub sensor.Lawv tsis xav tau cov khoom siv hluav taws xob sab nraud, cov qauv sib txuas dual thiab A / D converters.

    Tag nrho cov khoom siv hluav taws xob xav tau rau kev nyeem ntawv yog tsim rau hauv lub sensor.Ib lub nti tsuas yog xav tau lub zog huv huv los muab cov duab zoo thiab tuaj yeem nyeem tawm ncaj qha digitally.Qhov no yog vim li cas CMOS sensors muaj qhov zoo dua ntawm cov nqi.
