CMOS-masanjidwewo: zizindikiro ntchito ndi ntchito chipangizo

CMOS-masanjidwewo - chipangizo amene Ntchito yaikulu ndi digitization la magawo ena kunyezimira kuwala kumene inu pamwamba. awiri mawerengetsedwe muyezo ntchito masiku ano kujambula ndi vidiyo zida: CMOS ndi CCD. Nkhaniyi khama tikayerekezera umisiri ndi awiri.

zambiri

Choncho, CCD-masanjidwewo. Mtundu poyamba ankaona wapamwamba kwambiri, komanso mphamvu kwambiri ndi yokwera mtengo. Mfundo ntchito zipangizo n'kozikidwa pa mndandanda wa chithunzi lonse mu Baibulo analogi, kenako digitization. CMOS-masanjidwewo, mosiyana mpikisano ake, digitizes lililonse mapikiselo payekha.

Kuyerekezera matekinoloje awiri

CMOS-zipangizo Poyamba zochepa energopoteblyayuschimi ndi wotsika mtengo, makamaka ndi kupanga zipangizo lalikulu kukula, koma wolephera CCD khalidwe. Kuti lero, CCD-luso zambiri apamwamba images, iwo ntchito zosiyanasiyana za sayansi ndi mafakitale, kumene khalidwe la fano woyikidwa zofunika apamwamba. Mwachitsanzo, mankhwala.

M'zaka zaposachedwapa, mtundu wa zida ali kwambiri yafupika mowa mphamvu ndi ndalama, koma CMOS-masanjidwewo patsogolo kwambiri chitukuko. Mwachitsanzo, anali angwiro ndipo anapezerapo gawo lina la muyezo fano khalidwe. Komanso, luso la zopangapanga mu kupanga masensa zochokera CMOS-luso chaonekera, akuti aliyense chithunzi mapikiselo wakhala akuyendera kuwerenga transistor mkuzamawu. Izi walola kubala mlandu voteji kutembenuka mwachindunji pa mfundoyo. Ndi CMOS-masanjidwewo wakhala ndime ndi CCD-sayansi. Ndipo tsopano zipangizo zambiri zamakono zachokera chipangizo zochokera CMOS.

Ubwino CMOS-luso

Mwachidule pamwamba, Tiyeni tifupikitse ubwino zipangizo zimenezi. Izi otsika mowa mphamvu mode malo amodzi, mtengo wotsika wa opanga (makamaka poganizira mkulu kusamvana CMOS-masanjidwewo). Koma mwayi chofunika kwambiri ndi luso kupereka wokonzeka digito chizindikiro, amene sikutanthauza kutembenuza zina.

Ntchito CMOS-luso mu makompyuta

Aliyense wosuta zida zamakono kompyuta tsiku lililonse takumana ndi chipangizo monga ukonde-kamera. Koma ochepa mukudziwa kuti zachokera pa mfundo za CMOS-sayansi. Web-kamera ntchito monga munthu zinchito chipangizo, ndi ophatikizidwa Mwachitsanzo mu Malaputopu. zipangizo amenewa anapangidwa kuti ntchito ndi ntchito kompyuta matumizidwe ophatikizika amawu, nyimbo ndi zithunzi. The zikuchokera mankhwala anati zikuphatikizapo: a mandala zosiyanasiyana, kanema adani khadi, ndi fyuluta kuwala, fano psinjika wagawo, ndi purosesa, kung'anima kukumbukira, ukonde-Seva, ndi mawonekedwe maukonde. The masanjidwewo ndi maziko a camcorder kapena fotoappatara. Chifukwa khalidwe la fano opatsirana kudzadalira chigamulocho chipangizo. chizindikiro Izi kawirikawiri mu makamera intaneti ali mu osiyanasiyana kuchokera 0,1 2 megapixels. Komabe, mankhwala ambiri ndi 0,3 megapixels. Chinanso kudziŵa webukamu amachita chimango mtundu. Wotchuka kwambiri ndi masanjidwewo CMOS 1/4. Pali akamagwiritsa zina, koma iwo sakhala wamba (mwachitsanzo, 1/3, 1/2 kapena 2/3 la inchi).
