Yini engcono: CCD okanye iCMOs? nendlela yokukhetha

Matrix - sisiseko nayiphi na ifoto okanye ividiyo. Sichaza umgangatho kunye nokusombulula lo mfanekiso. Namhlanje ekwenziweni matrices kusetyenziswa ezimbini ezahlukeneyo zeteknoloji mgaqo - CCD kunye iCMOs. rhoqo uyakwazi ukuva lo mbuzo: "Luhlobo luni matrix khetha :? CCD okanye iCMOs» Phakathi abalandeli photo kunye nezixhobo video kulo mba iingxoxo shushu. Kweli nqaku, siza kuxubusha ezi ntlobo zimbini ze uzame uku bana phandle ezona matrix - CCD okanye iCMOs.

ulwazi jikelele

Le matrices zenzelwe ukuba zifake parameters semitha ukukhanya phezu komhlaba. Bathi akukho luncedo olucacileyo omnye iiteknoloji kunokwenzeka. Uyakwazi ukwenza uthelekiso kwi ezithile parameters nokuchonga inkokheli aspect omnye okanye omnye. Ngokumalunga kukhetho kubasebenzisi ', ntonje njengenqobo zazo eziphambili lixabiso le mveliso, nokuba uya kuba enasilela umgangatho okanye nengcombolo okhuphisanayo yayo.

Ngoko ke, makhe sibone ukuba yintoni na iintlobo ezimbini izixhobo. CCD-matrix - sinochuku, nto leyo ubunjwe photodiodes ukukhanya-ethe-ethe; wadala isekelwe lesilicon. Le peculiarity yomsebenzi wakhe kuxhomekeke kumgaqo isixhobo operation kwentlawulo-luhlangene. ICMOs-matrix - isixhobo olusekelwe semiconductor transistors isiphumo entsimini ukuba i isango igqunyiwe ukusuka imijelo conductivity ezahlukeneyo.

isimiso ukusebenza

Makhe nisinga ekuboneni umahluko eziya kukunceda ukuba wenze ukhetho: kokona kulungileyo - a iCMOs matrix okanye CCD? Umahluko omkhulu phakathi kwezi bugcisa ezimbini zisebenza njani. CCD-unit isigxina ukusuka pixels iguqulelwa amandla yombane leyo ziyanyuswa ngaphaya boluvo photosensitive. Isiphumo umfanekiso ekwimo analog. Emva koko yedijithi yonke umfanekiselo ADC. Oko kukuthi, ifowuni iquka iinxalenye ezimbini - isizalo ngqo kunye lokuguqulela. ICMOs-technology ungachazwa ukuba lenguqu uvelisa pixel ngamnye. Le mveliso sele umfanekiso wedijithali ukulungele. Oko kukuthi, kagesi oluhlala kwi pixel isizalo kwi ekondensa, awanyakazela ngayo amandla wombane isusiwe. Oku idluliselwe wokukhulisa analog (ibephakathi ngqo kwi-pixel), ngoko idijithali kwi lokuguqulela.

Yintoni ukukhetha: CCD okanye iCMOs?

Enye i parameters ezibalulekileyo ezibonakalisa ukhetho phakathi kwezi ubuchule linani yokukhulisa matrix. ICMOs-yobuchwepheshe iye inani elikhulu lwezixhobo (ngaxa nganye), ukuze uphawu passes yehliswe kancinane izinga image. Ngoko ke, lo CCD-matrix ziyasetyenziswa ukwenza imifanekiso ngezinga eliphezulu nkcukacha, umzekelo, kuba zonyango, uphando kunye iinjongo zoshishino. Kodwa ke iCMOs-iteknoloji isetyenziswa ikakhulu kwizixhobo ekhaya: iikhamera web, iifowuni, amacwecwe, laptops, njalo-njalo ..

Parameter elandelayo egqiba loluphi uhlobo olungcono - CCD okanye iCMOs, - kokona kuxinana le photodiodes. I aphezulu oko kukuthi, i photons mbalwa "zalahleka lilize," ngokulandelelana, umfanekiso uya kuba ngcono. Kule ndawo, CCD-matrix uzakufun aukugqithisa kontanga yayo, njengoko inika layout engenayo izithuba ezinjalo, ngelixa iCMOs langoku (balungiselela transistors).

Noko ke, xa phambi umsebenzisi ufumana ukhetho: Yeyiphi uhlobo matrix - i iCMOs okanye CCD - kuthenga pops up i parameter engundoqo - ixabiso kwefowuni. CCD-technology ngokuphawulekayo kubiza ngaphezu ekhuphisana kwayo, kunye nokusetyenziswa kwamandla. Ngoko ke, ukuba awamise apho umgangatho umndilili umfanekiso kwanele, bekungalunganga.
