Inkambu yelensi yokugada ezokuphepha
Inombolo yomkhiqizo | Into | Inani |
1 | EFL | 3.6 |
2 | F/NO. | 2 |
3 | I-FOV | 160° |
4 | I-TTL | 22.18 |
5 | Usayizi Wenzwa | 1/2.5” |
I-3.6mm yobude obufushane bokugxila yokuvikela ilensi yokugada enencazelo ephezulu, izithombe zamaphikseli ayizigidi ezingu-5 zekhwalithi ephezulu, ukukhetha kokuqala kokugada okunokucaca okuphezulu nokuqopha ukushayela.Ilensi yokuzikhethela yemikhiqizo ephezulu yaseChina.
Isithombe esingenhla sibonisa ukuqonda okunembile kwenkambu yokubuka yamalensi amade namafushane obude bokugxila
I-EFL(ubude bokugxila obusebenzayo)
Ifomula yobudlelwano: 1/u+1/v=1/f
Ibanga lento: u Ibanga lesithombe: v Ubude bendawo: f
Okungukuthi, ukuphindaphinda kwebanga lento kanye nokuphindaphinda kwebanga lesithombe kulingana nokuphindaphinda kobude bokugxila.
I-TTL(Ingqikithi Yobude Bengoma)
Ubude obuphelele belensi buhlukaniswe ngobude obuphelele bama-optics
kanye nobude obuphelele bomshini.
Ubude obuphelele bokubona: bubhekisela ebangeni ukusuka endaweni yokuqala yelensi kulensi ukuya endaweni yesithombe.Kuboniswe njengesithombe esingenhla, i-TTL ingu-11.75mm
Ubude obuphelele bendlela: ibhekisela ebangeni ukusuka ekugcineni komphongolo welensi ukuya endizeni yesithombe.
I-MJOPTC ingenza ngendlela oyifisayo, icwaninge futhi ithuthukise amalensi okuqapha okuphepha ahlobene noma inikeze ukubambisana kwe-OEM/ODM ngokuya ngezidingo zekhasimende.
Izinto ezine ezinkulu ezinquma umthelela wokuthwebula wekhamera:
|
|
| |
Ilensi | Imbobo | Inzwa yesithombe | Gcwalisa ukukhanya |
Isilayidi selensi | Isixazululo | isibani | |
Ukudluliswa kokukhanya | Ukungena okuncane | Usayizi wephikseli | Uhlobo |
Ukuzwela | Amandla Obuningi | ||
Izingxenyekazi zekhompuyutha | Ithonya | Uphawu lwekhono | |
Ilensi | Inquma izinga lokuncishiswa kokukhanya okudlula kusilayidi selensi | Ukudlulisa ukukhanya | |
Imbobo | Inquma inani le-flux ekhanyayo etholwe ikhamera ngesikhathi esifanayo | Ikhono lokungena elikhanyayo | |
Inzwa yesithombe | Uma inzwa yesithombe iba nkulu, amaphikseli aba makhulu, nokusebenza kwe-photosensitive kunamandla. | Ukuzwela | |
Gcwalisa isibani esikhanyayo | Uhlobo nenombolo yezibani zokugcwalisa inquma uhlobo lwekhamera | Gcwalisa ikhono lokukhanya |
Izingxenye ezimbili zokuqala zemiphumela engenhla zinqunywa ilensi
Qaphela: Umthelela wesithombe nawo uhlobene eduze nekhono lokushuna le-ISP kanye nokuhluzeka kokuhlanganiswa kwamalensi.
Ibanga lokusebenza elivame ukusetshenziswa cishe liphindwe izikhathi ezingu-50 ubude bokugxila, ngakho-ke kuyadingeka ukuqinisekisa ukuthi leli banga linekhwalithi enhle yokuphambuka.
F/NO
Ngokuvamile, ukuzwela kwamakhamera okuphepha kuphansi kakhulu.Endabeni yokukhanya kwangaphakathi, indawo yokuvula ilensi ingahlangabezana ngokuyisisekelo nezimfuneko lapho isetshenziselwa u-F1.6~F3.8.Ukukhanya kwangaphandle ngokuvamile kuphakathi kuka-F3.5~F10.Ngenxa yesikhala esilinganiselwe sasendlini, amalensi anobude bokugxila ngaphezu kuka-20mm awavamile ukusetshenziswa.Kuleli phuzu lokubuka, kwilensi engaphakathi kuka-20mm, kudingekile kakhulu kuqala ukuqinisekisa ukuthi indawo ezungeze i-F1.6~F3.5 inekhwalithi yesithombe engcono.
Kulensi enobude obugxilwe obungaphezu kuka-50 mm, Kufanele iqale iqinisekise ukuthi inekhwalithi yesithombe engcono ngaphakathi kwembobo ye-F8 ngenxa yokuthi ivame ukusetshenziselwa ukuthwebula izithombe kwasemini yangaphandle, ngaphandle kwalokho, inombolo ka-F kufanele ifinyelele ku-F1.0 .ngoba ilensi yayo ikakhulukazi isetshenziselwa ukuqapha ibanga elide ebusuku, Ngakho-ke, kuyadingeka ukuba nekhwalithi yesithombe esihle ngaphansi kwesimo sokuvula isihlobo esikhulu.
Kumalensi asemini nasebusuku, kuyadingeka ukuqinisekisa ikhwalithi yesithombe ngaphakathi kwebanga lokuvula elibanzi.
I-MJOPTC ingenza ngendlela oyifisayo, icwaninge futhi ithuthukise amalensi okuqapha okuphepha ahlobene noma inikeze ukubambisana kwe-OEM/ODM ngokuya ngezidingo zamakhasimende.
