Ndezvipi zviri nani, CCD kana CMOS? nzira dzekuziva nadzo sarudzo

Matrix - ndiyo nheyo chero mufananidzo kana mavhidhiyo. It nekutsanangura unhu uye kwemupfungwa chifananidzo. Nhasi ari zvaAtemisi matrices vakashandisa mbiri dzakasiyana rwokugadzira musimboti - CCD uye CMOS. Kakawanda unogona kunzwa mubvunzo: "worudzii chizvaro sarudza :? CCD kana CMOS» Pakati mafeni ose Photo uye mavhidhiyo midziyo munaizvozvo pokuti. Munyaya ino, tichaongorora marudzi aya maviri uye edza kufunga kuti zvakanaka chizvaro - CCD kana CMOS.

Vhuṱanzi

The matrices akagadzirirwa akakunda parameters chiedza mwaranzi pamusoro pemvura. Vanoti hachisi nani yakajeka mumwe inobvira ruzivo. Unogona kuita kuenzanisa dzakananga parameters uye kuziva mutungamiri chimwe kana mumwe. Panyaya vanoshandisa 'zvaunofarira, kazhinji dzinonyanya chokuratidza mutengo chigadzirwa, kunyange kana zvichava vakaderera unhu kana nokurondedzerwa kwayo mukwikwidzi.

Saka, ngationei kuti ndiyo mhando mbiri namano. CCD-chizvaro - a Chip, iro rinoumbwa chiedza-tisanzwe photodiodes; zviri akasika yakavakirwa nesilicon. The peculiarity basa rake iri nheyo kushanda vebasa-akabatanidza mudziyo. CMOS-chizvaro - zano kunobva semiconductor munda maturo transistors ane insulated gedhi kubvira hova yakasiyana conductivity.

musimboti oparesheni

Ngativhurei kuti kuziva kusiyana huchatibatsira kuita chisarudzo: riri nani - a chizvaro CMOS kana CCD? Musiyano mukuru pakati izvi ruzivo mbiri sei vanoshanda. CCD-chikwata mutariri kubva pixels vari kuchinjwa kuva yemagetsi zvinogona riri yakakura kupfuura photosensitive sensors. Zvinoguma chifananidzo analoginen chimiro. Pashure digitization chifananidzo yose ADC. Kureva kuti mudziyo rine zvikamu zviviri - chizvaro zvakananga uye convert. CMOS-zvemichina kunoratidzwa muna kuti digitization unobereka mumwe Pixel nomumwe. The goho kwatova vakagadzirira-digital mufananidzo. Kureva, yemagetsi mutariri rinoungana ari Pixel chizvaro iri condenser, nako yemagetsi zvinogona chinobviswa. Zvinonzi chakasvitswa kuti analoginen gudzazwi (midzi zvakananga Pixel), ipapo digitized ari convert.

Chii kusarudza: CCD kana CMOS?

Mumwe parameters zvinokosha kuti tizive kusarudza pakati izvi maitiro inhamba amplifiers chizvaro. CMOS-mano vane hombe nhamba mano (nechimwe nguva), saka kuti chiratidzo pemipata zvishoma shoma mufananidzo unhu. Naizvozvo, kuti CCD-chizvaro anoshandiswa kusika mifananidzo rurefu mwero zvakadzama Somuenzaniso, kwezvokurapa, kutsvakurudza uye maindasitiri zvinangwa. Asi CMOS-zvemichina rinoshandiswa kunyanya kumusha midziyo yemagetsi: padandemutande makamera, smartphones, mapiritsi, Laptops, uye zvichingodaro ..

Rakatevera parameter kuti anosarudza hworudzii nani - CCD kana CMOS, - ndiye arambe achirema pakati photodiodes. The yepamusoro kwayo, photons vashoma "akarasika pasina," ukuwo, mufananidzo zvichava nani. Mudare iri, CCD-chizvaro yokunzvenga vakwikwidzi dzayo, sezvo rinopa marongerwo kuti haana Makwanza zvakadaro, panguva ino CMOS (vakaronga transistors).

Zvisinei, kana pamberi User awana chisarudzo: Ndoupi mhando chizvaro - the CMOS kana CCD - kutenga zvabuda huru parameter - mutengo mudziyo. CCD-zvemichina zvimwe yekudyidzana anodhura pane mukwikwidzi kwayo, uye simba rakawanda. Naizvozvo, kuti avasimbise apo avhareji unhu nomufananidzo yakakwana, zviri kukodzera.
