Ukulinganisela kwezilense zemodi yekhamera

Izinkanyezi ezindaweni zemfotolozi ziyindlela ebalulekile yokufocela kwi-sensor ye-imijikajet. Ukuzazi imboni nokusebenza kwesinkanyezi kuyadinga ukukhetha imoduli yemfotolozi ekhethiwe. Phezulu kukhona ukulandelwa okuphelele kwezinkanyezi zemoduli yemfotolozi:

Ukusebenza okuthiwa yiLens

Isifinyezo esikhulu sokuqinisekisa ukukhanya okuphuma noma okuphazamisa kwezinto ekwenziwe kusukela kwi-sensor yeemayiphoto. Lokhu kwenza ukuthi isignal esikhanya sivikele isignal ye-elekthirikhi. Ububanzi bokufinyelela kwenza kube nomthelela omuhle, ukulungiswa kwesakhiwo, futhi umsebenzi wonkana wokwenza imodeli esisendaweni.

Izici ezimbili zokwenza isihloko

Izinto zokubuka kubalulekile kakhulu kusukela kwezinye izinto ezimbili zokubuka, ezinikezelwe ngomphumela wemilenze, okungaba ngokwezomphumela noma ngokwezomphumela. Izinkomba zezomphumela ezithandwayo zihlanganisa:

1P: 1 lens -> 1P: 1 isihlathi

2P: 2 amalenza amakhulu

1G1P: 1 ilenza yomlilo 1 ilenza yomthetho

1G2P: 1 iglasi 2 amalenza okanye amalensi eplastiki

2G2P: 2 amalenza amashumi amabili nezimbobo ezimbili

4G: 4 izinkanyezi zomlilo

Inombolo kanye nesidingo sezinkanyezi zivame ukulimala nokusebenza kwesidingo. Kusukela kubhokisi zinkanyezi zingaba ngcono kunazo ezincane kodwa zivame imiphumela encane.

Izinto ezimbili zokubuka

Izingqimba zegilazi (GLASS): Zinikeza ukuphazamisa okuhle kwesilwane samanzi kanye nokushisa okuphansi, ezokwakhiwa kwezinto ezinkulu.

Plastic Lenses (PLASTIC): Lower, but with poorer light transmission and durability.

Izingxenye Zokwenza Isilawuli

Izinga Lokufocaza: Kwenza ukubuka kanye nokuphila kwesimo. Izinga elincane lizokwazi ukubuka okulula; izinga elikhulu lizokwazi ukubuka okuncane.

Indawo yokubuka (FOV): Inikeza isikhala sesikhathi esingabonakaliyo esikhumulweni sokubuka okwengeziwe; izikhathi ezimbalwa zinikeza isikhala sesikhathi esingabonakaliyo esikhumulweni sokubuka okushesha.

Inombolo ye-F (Isikrini): Iphakathi ukubonakala kwe; inombolo ye-F encane ikhombisa isikrini esikhulu kanye nokungena kwesilisa okukhanya ekhishini, okuyinto ekwakhiweni okuphakade.

Ukubuka: Kwenza ukuthi isibani esikhanyayo sibuke ngokuthi siqinisekise ubude bese siqinisekisa ukubonakala.

Indawo Yezinkanyezi: Uma isithombe sifanele, indawo kusukela kusithombe kuya ekupheleni kusithombe.

5. Izici Zokwenza Lens

Ukucacisa Ukushuba: Iqinisekisa ukukhanya okungaphansi kwelelensi ukuze kube nokukhanya okuphelele nokukhanya.

Isithombe Sharp: Ithembisa ukuthi isithombe sihlanzekile phakathi kwemibala ethile.

I-CRA (Chief Ray Angle): Kumele i-CRA yomqondo wemfihlo ikhombisele ukuqondisa izithombe.

Ukukhanya Okukhulu: Isikali esikhulu sibonisa ukuthi izibani eziningi zingena, okuyinto ekwakhiweni okuphakathi.

Ukubonisa: Kwenza kube kancane ukubonisa okukhulu kwezibuko ukuze kube nokwenzeka kwesimiso sezibuko.

6. Izinhlobo zezibukeli

Izinhlelo ezahlukene zinamathuluzi amabhokisi amabhokisi:

Izilayini zemidlalo: Bheka ukuthi kukhona ukuphazamiseka okuphezulu, ukufaka isithombe ngokushesha kanye nokwenza okuhle ekukhanyeni okuncane.

Ukubuka: Fokusela ukukhanya okwesibili, izibukeli ezilula, kanye nokulungiselela okuphelele.

Izimoto ezivuselela: Zidinga izikhathi eziningi zokujikeleza okuphezulu, izikhathi zokuphendula ngokushesha, futhi ukulinganiselwa okuphezulu kwemida.

Izindlela Zokwenza I-Lens

Ukudibanisa: Isixhumi phakathi kwelense kanye ne-PCB kufanele kwenziwe ngesimo. Izici ezahlukene zezindlela zokudonsa zingasebenzi kahle futhi zingasebenzi kahle. Izindlela ezintsha zezigaba zisebenzisa izinto zokwenza isimo (njengoba i-infrared noma i-ultraviolet light) zokwakha ukusebenza kahle kanye nokwakha okuphelele.

Ukugcina

Ukukhetha ilenza elihambisana kakhulu le-camera module kuyadingeka ukwenza ukulawula okuphelele kwemifanekiso emikhulu, kusukela embonini we-lens, izici zokudala, izici zokwenza, kanye nezici zokusebenza. Ilensa elihle kakhulu kungenzeka ukwenza ukulawula okuphelele kwemodule ye-camera, ekwenzeni kube kuhle kanye nokulungisa izithombe ezivela emikhakheni emihle.
