Mufananidzo we CMOS werudzi rwemapikicha tekirinesi mukati meimwe makamera ekudhijita, ane sangano rinosanganiswa rinonyora mufananidzo. Iwe unogona kufungidzira nezvechitema chemufananidzo sechichifananidzirwa nefirimu mune imwe yekare firimu kamera.
Iyo yakawedzera metal-oxide semiconductor (CMOS) sensor ine mamiriyoni epixel sensor , imwe neimwe inosanganisira photodetector. Sezvo chiedza chinopinda mukhamera kuburikidza ne-lens, inowanzoita sensor image CMOS, iyo inokonzera imwe photodetector kuunganidza mutero wegesi zvichienderana nehuwandu hwechiedza chinouraya. Iyo kamera yemagetsi inotendeuka iyo iyo kuverengera kuverengera yedijiti, iyo inotarisa simba rechiedza chakayerwa pane imwe photodetector, pamwe nemuvara. Iyo software inoshandiswa kuratidza zvifananidzo inoshandura iyo kuverengwa mumapiksesi ega anoita mufananidzo apo paanoratidzwa pamwe chete.
CMOS Vs. CCD
CMOS inoshandisa teknolojia yakasiyana zvakasiyana kubva kuCCD, iyo imwe mhando yechinhu chemajeri chinowanikwa mumakamera e digital. Mamwe makamera e digital ari kushandisa CMOS teknolojia kupfuura CCD, nokuti masero CMOS image anoshandisa simba shoma uye anogona kudhinda dhichi kupfuura CCD. CMOS sensor sensor inowanzoita mari shoma kupfuura CCD.
Mumazuva okutanga emamera makamera, mabheti aiva makuru nokuti makamera akanga ari makuru, uye saka CCD yakashandiswa simba guru rakanga risina basa rinokosha. Asi sezvo kamera dzedhijita dzakaputika muhukuru, dzinoda mabheti maduku, CMOS yakava sarudzo yakanaka.
Uye sezvo zviratidzo zvemufananidzo zvaona zvichiwedzera mukuwanda kwepiksesi dzavanonyora, kukwanisa kwechimiro chemufananidzo we CMOS kutamisa data nokukurumidza pachi chipu uye kune zvimwe zvikamu zvekhamera neCCD zvinove zvinokosha.
Kubatsirwa kwe CMOS
Imwe nzvimbo iyo CMOS inonyanya kukoshesa pane mamwe magetsi ekugadzirwa kwechifananidzo ari mumabasa ayo anokwanisa kuita pane chip, panzvimbo yekutumira dhidhiyo yemifananidzo kudhidhi firmware kana software yehumwe hutano hwemabasa. Somuenzaniso, sensor image ye CMOS inogona kuita zvigadziro zvekunonoka kwekwaniso zvakananga chip, iyo inoponesa nguva kana ichifambisa data mukati mekhamera. Mucherechedzo we CMOS uyewo unozoita analogog kumatende ekutendeuka kwechidimbu pane chip, chimwe chinhu cheCCD sens sensor hachigoni kuita. Mamwe makamera achaita basa rekudzivirira pamusana we CMOS, iyo inovandudza zvakare kukera kwekamera kwekushanda.
Kuvandudzwa Kunoenderera mberi muCMOS
Sezvo vakugadziri vemamera vakatamira zvakawanda kuTV teknolojia yezvinoridziro zvemifananidzo mumakamera, tsvakurudzo dzakawanda dzaenda mune teknolojia, zvichiguma nekuvandudza kwakasimba. Semuenzaniso, apo maCCD sensor sensors anoshandiswa kuva akadhura kupfuura CMOS yekugadzira, kuwedzera kwekutsvakurudza kunowanikwa ma sensor image CMOS kwakabvumira kuti mari ye CMOS ienderere mberi.
Imwe nzvimbo iyo kusimbiswa kwekutsvakurudza kwakave kwakabatsira CMOS iri mune teknolojia yepamusoro. CMOS sensor sensors dzinoramba dzichiratidza kuvandudza mukukwanisa kwavo kukodha mifananidzo nemigumisiro yakaisvonaka mukutsika mifananidzo. I-on-chip noise ukuncipisa zvigadziriro zve CMOS yakaramba ichiwedzera mumakore achangobva kupfuura, zvichivandudza kukwanisa kwechimiro chemufananidzo we CMOS kuita zvakanaka muchechi.
Imwe humwe huri nani kuvandudzwa kuCMOS kwaiva kuiswa kwekwenyeri yechinhu chinonzi teji teknolojia, iyo inowanzoendesa dhamusi kubva kune chinyorwa chemufananidzo kuenda kunekamera yakatamiswa kubva mberi kwechiedza chemufananidzo - pairivhara chimwe chechiedza chinopisa sensor - - kumushure, zvichiita kuti sensor image CMOS isakwanisa kuita zviri nani muchitsetse chechidiki, nekuchengetedza kukwanisa kwechi chipfuuridzo kutora dhigirii nekukurumidza kwepamusoro pemasenenji eCCD image.
