CMOS-chizvaro: features, mashandiro uye kushanda ari mudziyo

CMOS-chizvaro - zano ane basa chikuru ndicho digitization vamwe parameters vechiedza nemwaranzi anouya panyika. maviri mureza matrices akashandiswa ano mifananidzo uye mavhidhiyo midziyo: CMOS uye CCD. Nyaya iri vakazvipira kuti kuenzanisa ruzivo maviri.

Vhuṱanzi

Saka, CCD-chizvaro. Izvi mhando pakutanga vaiona chemhando yepamusoro, asiwo nesimba rakawanda-nyanyisa uye zvinodhura. Nheyo kushanda zvakadaro mano inobva kuunganidzwa pamufananidzo yose iri analoginen shanduro, zvichiteverwa digitization. CMOS-chizvaro, kusiyana kwayo mukwikwidzi, digitizes mumwe Pixel nomumwe.

A fananidzo ruzivo maviri

CMOS-mano vakanga pakutanga zvishoma energopoteblyayuschimi uye chisingakoshi, ichi ichokwadi kunyanya pakubudiswa guru saizi mano, asi dzakaderera CCD unhu. Nanhasi, CCD-muzvigadzirwa zvitsva zvakawanda yepamusoro mifananidzo, vari kushandiswa muminda siyana sayenzi uye maindasitiri, apo kunaka mufananidzo waiita chikuru zvinodiwa. Somuenzaniso, mune zvokurapa.

Mumakore achangopfuura, kwakadai midziyo iri yekudyidzana akaderedza simba zvinodyiwa uye cost, asiwo CMOS-chizvaro zvinokosha mberi kwayo kukura. Somuenzaniso, zvakanga rikapedzwa uye kurwisa kuva itsva azvipire mufananidzo yepamusoro vomureza. Uyezve, kwezvinhu yechimurenga anogadzira zvinhu sensors kwakavakirwa CMOS-zvemichina kwaitwa, kureva kuti mumwe mufananidzo Pixel yave chinozoiswa kuverenga transistor gudzazwi. Izvi akabvumira kuti pave mutariri voltage kutendeuka zvakananga achitandadza. With ichi CMOS-chizvaro rava ndima chete CCD-rwokugadzira. Zvino kupfuura ano mano chakavakirwa mudziyo kunobva CMOS.

Zvakanakira CMOS-zvigadzirwa

Nokupfupikisa apa, tinogona muchidimbu zvakanakira vakadaro mano. Ichi pasi simba kudyiwa mu kunofambira mberi rudzi, pasi mutengo mukugadzira (kunyanya kufunga yakakwirira chisarudzo CMOS-chizvaro). Asi chinonyanya kukosha anobatsirwei kukwanisa kupa vakagadzirira digitaalinen chiratidzo, izvo haatarisiri okuwedzera kutendeuka.

Kushandiswa CMOS-michina iri zvemichina kombiyuta

mushandisi nerimwe midziyo kombiyuta yemazuva zuva ose nemamiriro mudziyo akadai web-kamera. Asi vashoma vanoziva kuti zvakavakirwa panheyo CMOS-zvigadzirwa. Web-kamera inoshandiswa sezvo munhu dzichipfekeka mudziyo, uye midzi somuenzaniso muna Laptops. Kwakadaro mano akagadzirirwa kushanda networked Multimedia zvikumbiro. The Zvinoumba akati chigadzirwa zvinosanganisira: kuva izvo wakazvigadzira, mavhidhiyo kubatwa kadhi, imwe Manyiminya Sefa, chifananidzo compression Unit, mumwe processor, nokupenya ndangariro, web-Server, uye nomumbure inowanikwa. The Matrix ndiyo hwaro chero camcorder kana fotoappatara. Nokuti chatingatevedzera zvitange mufananidzo achaenderana chisarudzo pamusoro mudziyo. parameter Izvi kazhinji zviri padandemutande makamera iri zvinobva 0.1 2 megapixels. Zvisinei, mune mishonga yakawanda iri 0.3 megapixels. Chimwe kuziva Webcam anoita pepuranga format. Chinonyanya dzakakurumbira ndiyo chizvaro CMOS 1/4. Kune dzimwe zvinogona, asi ivo vari ishoma (semuenzaniso, 1/3, 1/2 kana 2/3 ane padiki).
