Iyo yakakosha chip yekamera - CMOS mufananidzo

sensor

A CMOS (inopindirana simbi oxide semiconductor) mufananidzo sensor's yekushandisa pfungwa yakafungidzirwa muhafu yechipiri ye1960s, asi mudziyo uyu hauna kutengeswa kusvika tekinoroji yemicrofabrication yashanduka zvakakwana muma1990s.CCD (charge coupled device) kana CMOS (complementary metal oxide semiconductor) mapikicha emifananidzo anowanzo shandiswa mumakamera emazuva ano edhijitari nenharembozha.

CCD neCMOS ese ari maviri semiconductor zvishandiso zvinoshanda se "maziso emagetsi."

Ivo vese vanoshandisa mafotodiode, asi maitiro avo ekugadzira uye nzira dzekuverenga zviratidzo zvinosiyana.Kunyangwe tekinoroji yeCCD yaive yakakurumbira pakutanga nekuda kwekunzwa kwepamusoro uye mhando yemifananidzo, masensa eCMOS akatanga kupfuura maCCD sensors mukutakura vhoriyamu kutanga mu2004.

Nhamba yedata inokurumidza kupfuura CCD.
Ruzhinji rwema capacitor mune inochaja-yakabatana mudziyo (CCD) mufananidzo sensor inotakura electric charge zvinoenderana nechiedza chepixel.Yese zviri mukati me capacitor zvinoendeswa kune muvakidzani wayo kuburikidza nedhiraivha yekudzora, uye yekupedzisira capacitor muhurongwa inodurura chaji yayo mune yekuchaja amplifier.CCD sensors dzinozivikanwa nenzira yavo yebhaketi-brigade yekufambisa data.

Iyo inopindirana nesimbi oxide semiconductor (CMOS) mufananidzo sensor

kune rimwe divi, ine photodiode uye CMOS transistor switch yepixel yega yega, iyo inobvumira mapixel masaini kuti akudzwe zvakasiyana.Iwo mapikisi masaini anogona kuwanikwa zvakananga uye zvakateedzana, zvakakurumidza zvakanyanya kupfuura CCD sensor, nekushandisa matrix ekuchinja.Imwe mukana wekuva neamplifier yepixel yega yega ndeyekuti inoderedza ruzha rwunosimuka uchiverenga masaini emagetsi akashandurwa kubva kuchiedza chakaunganidzwa.

CMOS image sensors inodhura kugadzira kupfuura CCD image sensors nekuti iripo semiconductor yekugadzira michina inogona kushandiswa zvakare kugadzira yavo.Kusiyana neCCD sensors, inoshandisa high-voltage analog circuits, CMOS sensors inoshandisa diki diki yedhijitari iyo inoshandisa simba shoma uye iri, mukufungidzira, isina smear (yakamira chena streak mumufananidzo wakajeka-chiedza) uye inotumbuka (huori hwemifananidzo yakadaro. semavara machena).Nekuti logic yedunhu inogona kuisirwa pane chip panguva yekugadzira, maCMOS sensors ane on-chip mufananidzo wekugadzirisa wedunhu ari kugadzirwa maapplication akadai sekucherechedzwa kwemufananidzo uye kuona kwekugadzira, aine mimwe michina iri kushandiswa parizvino.

Ronghua, inogadzira inyanzvi muR&D, kugadzirisa, kugadzira, kutengesa uye sevhisi yemamodule kamera, USB kamera modules, lenzi uye zvimwe zvigadzirwa.Kana uchida kutibata, ndapota:
