CMOS-matrix: nta, zog thiab khiav hauj lwm ntawm lub ntaus ntawv

CMOS-matrix - ib tug ntaus ntawv uas nws lub ntsiab muaj nuj nqi yog lub Digitisation ntawm tej ciaj ciam ntawm lub teeb rays uas tuaj rau ntawm qhov chaw. ob txheem matrices siv nyob rau hauv niaj hnub photography thiab video khoom: CMOS thiab CCD. Qhov tsab xov xwm yog mob siab rau mus rau ib tug sib piv ntawm ob technologies.

lus qhia dav dav

Yog li ntawd, CCD-matrix. Qhov no hom yog Ameslikas xam tau tias yog lub siab tshaj plaws zoo, tab sis kuj xav paub ntau zog-intensive thiab kim heev. Lub hauv paus ntsiab lus ntawm cov lag luam ntawm tej pab kiag li lawm yog raws li nyob rau hauv tus sau los ntawm tag nrho cov duab nyob rau hauv lub analog version, ua raws li los ntawm Digitisation. CMOS-matrix, tsis zoo li nws cov competitor, digitizes txhua pixel ib lub zuj zus.

Ib tug sib piv ntawm ob technologies

CMOS-pab kiag li lawm yog chiv tsawg energopoteblyayuschimi thiab pheej yig, qhov no yog tshwj xeeb tshaj yog muaj tseeb nrog zus tau tej cov loj loj kiag li lawm, tab sis lawv yog ua tsis tau zoo rau CCD zoo. Yuav kom qhov no hnub, CCD-technology ntau high-zoo dluab, lawv yog siv nyob rau hauv ntau yam teb ntawm science thiab kev lag luam, qhov twg zoo tshaj ntawm cov duab yuam lub siab tshaj plaws uas yuav tsum tau. Piv txwv li, nyob rau hauv cov tshuaj.

Nyob rau hauv xyoo tsis ntev los no, qhov no hom ntawm cov khoom yog significantly txo zog noj thiab nqi, tab sis kuj cov CMOS-matrix ua tseem ceeb kev kawm nyob rau hauv nws txoj kev loj hlob. Piv txwv li, nws twb zoo tag nrho thiab launched rau hauv ib tug tshiab theem ntawm cov duab zoo qauv. Tsis tas li ntawd, cov kev siv technology tshiab kiv puag ncig nyob rau hauv lub chaw ua khoom ntawm sensors raws li CMOS-technology lawm, namely uas ib cov duab pixel tau tau muab siv rau kev nyeem ntawv transistor amplifier. Qhov no tau tso cai los tsim xwb voltage hloov dua siab tshiab ncaj qha mus rau lub point. Nrog rau qhov no CMOS-matrix tau los ua ib tug par nrog CCD-technology. Thiab tam sim no lub feem ntau niaj hnub pab kiag li lawm yog raws li nyob rau hauv ib tug ntaus ntawv raws li nyob rau hauv CMOS.

Qhov zoo ntawm cov CMOS-technology

Ntsiab lus saum toj no, peb muaj peev xwm saib lub ntsab lug zoo xws li kiag li lawm. Qhov no tsis tshua muaj zog noj nyob rau hauv zoo li qub hom, tsis tshua muaj nqi ntawm raug (tshwj xeeb tshaj yog xav tias yuav tus siab daws teeb meem CMOS-matrix). Tab sis tseem ceeb tshaj plaws kom zoo dua yog muaj peev xwm muab npaj cov teeb liab, uas tsis yuav tsum tau ntxiv los pauv hloov.

Kev siv cov CMOS-technology nyob rau hauv computer technology

Txhua tus neeg siv ntawm niaj hnub lub computer cov khoom txhua txhua hnub confronted nrog xws li ib tug ntaus ntawv raws li ib tug web-koob yees duab. Tab sis ob peb yeej paub hais tias nws yog raws li nyob rau hauv lub hauv paus ntsiab lus ntawm CMOS-technology. Web-lub koob yees duab yog siv raws li ib tug neeg ua hauj ntaus ntawv, thiab kos piv txwv li nyob rau hauv laptops. Xws li no yog tsim los ua hauj lwm nrog networked multimedia daim ntaub ntawv. Muaj pes tsawg leeg ntawm hais tias cov khoom no muaj xws li: ib tug lens array, ib tug yees duab capture card, ib tug kho qhov muag lim, ib tug duab compression tsev, ib tug processor, flash nco, web neeg rau zaub mov, thiab network interface. Lub Matrix yog lub hauv paus ntawm tej camcorder los yog fotoappatara. Vim hais tias qhov zoo ntawm cov kis duab yuav yog nyob ntawm seb kev daws teeb meem ntawm lub ntaus ntawv. Qhov no parameter yog feem ntau nyob rau hauv web koob yees duab yog nyob rau hauv ntau ntawm 0.1 mus rau 2 megapixels. Txawm li cas los, nyob rau hauv feem ntau cov khoom nws yog 0.3 megapixels. Qhov zoo tshaj yuav txiav txim lub webcam ua ncej hom. Cov feem nrov yog cov matrix CMOS 1/4. Nws muaj lwm yam tawm tswv yim, tab sis lawv yog tsis tshua muaj heev (piv txwv li, 1/3, 1/2 los yog 2/3 ntawm ib nti).
