Umbono Phakathi Kwefokothi Lokukhetha Kwelense Yekhamera Nokulinganisa

Isambulo esikhathi esifanayo phakathi kwesandla somfotshaphu nesikhathi:

Indawo yokufocala: Isambulo esikhulu kusuka ekhishini lapho kufakwe khona isithombe (kukhona okuthiwa yi-sensor noma ifilimu).

Indawo yokubuka FOV kuyinto isibonakaliso sokubuka esiZuluIkhodi: Ikhodi lokubuka kwesikhala esilula olens iyalibuka.

Ukucacisa okuncane kwezindlela zokucacisa, okukhulu okukhulu kwezindlela zokucacisa, futhi okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukhulu okukh

Ukuphakama kwesikhathi sokubuka, ukuphakama kwesikhathi sokubuka, kanye nokuphakama kwesikhathi sokubuka, kanye nokuphakama kwesikhathi sokubuka.

Izinhlelo zokusetshenziswa kwezibuko zangaphandle zokubuka.

Imbande yokufocala: Kukhona kwezinye izikhathi phakathi kwama-2.8mm kanye nama-16mm.

Ukubuka: Isigaba esisodwa, 2.8mm lensi ingaba inikeza uhlobo lwe-FOV angle olukhulu ngokwengeziweka kwezinye izikhathi ngama-120 degrees, okuyinto enokwethenjelwa kwezindawo ezidinga ukubuka okukhulu, njengamagumbi noma amaholi.

Izinkomba ezithile: Izinkomba ezinezinyawo ezifushane zingakwazi ukunikeza izithombe ezivela ezindaweni ezifushane, kodwa zingakwazi ukunciphisa izindawo eziningi.

Izindlela zokusetshenziswa kwamathuluzi okukhanya okukhulu.

Imithambo yofaka: Kusukela ngo-16mm phezulu.

Izinkinobho zokubuka: Isibonelo, i-lens ye-16mm ingaba inikeza isikhala sokubuka esingaba ngokwengeziwe ngokwengeziwe kwe-19.8 amagredi, ekwakhiweni kwezinto ezidinga ukubuka emoyeni okwamanje, njengokubuka izinto ezinzima.

Izinkomba ezithile: Izinkomba ezinamakhulu amakhulu zingakwazi ukunikeza izithombe ezivela emadolobheni amakhulu, kodwa zingakwazi ukunciphisa izithombe ezifakwe emadolobheni amancane.

Indawo yokufocala ayikwazi kuphumelela kwi-FOV angle kodwa ikwenzela ukuthi i-DOF iyathintana. I-DOF iyacaca ngokwezifundo kusukela ekupheleni kwezisebenzi kuya ekuphambeneni okwenzelwe ukuthi kucace kahle. Okufuphiweyo indawo yokufocala, okuncane i-DOF, kunezinto ezithintayo ezingaba ngumuntu okhethile. Okwesikhathi eside indawo yokufocala, okuncane i-DOF, kunezinto ezithintayo ezingaba ngumuntu okhethile.

Ukukhula kwe-aperture kwenza kube nokubukeka kwesimo sokuphefumula. Ukukhula kwe-aperture okukhulu (inombolo ethambile ye-F) kwenza kube nokubukeka kwesimo sokuphefumula, kwenza kube nokubukeka okukhanya kwangaphambili nokungaphambili. Ukukhula kwe-aperture okuncane (inombolo ethambile ye-F) kwenza kube nokubukeka kwesimo sokuphefumula, kwenza kube nokubukeka okuhlanzekile kwangaphambili nokubonakalisa isibonelo.

Kwesokudala, kukhona umbono ophilayo phakathi nokulinganisa kwefokalini nezindlela zokubuka kwekhamela. Ukukhetha ifokalini elihle kanye nothwalo kuyinto enhle kakhulu ekwenzeni kube nomthelela omuhle kwezokuvikela.
