Ukuqhathanisa Ububanzi be-FOV ye-Module Lekhamera Izimo Zokusetshenziswa Ezihlukahlukene
Kwadalwa ngo 01.20
Emhlabeni wobuchwepheshe bokuthwebula izithombe, i-Field of View (FOV) ye-camera module ingaphezu nje kwencazelo yobuchwepheshe—iyisixhumanisi phakathi kwamakhono edivayisi nezidingo zangempela zomsebenzisi. Noma ngabe uthwebula indawo ebanzi nge-drone, uskene ibhakhodi esitolo, noma uthatha i-selfie nge-smartphone yakho, ububanzi be-FOV obufanele bungakhuphula noma buchithe ikhwalithi nokusetshenziswa kwesithombe. Nokho, ngokuba khona kwezinketho eziningi ze-FOV (kusuka kumalensi amancane angama-20° kuya kuma-fisheye abanzi kakhulu angama-170°), ukukhetha okulungile kuvame ukuba nzima.
Lo mhlahlandlela usebenzisa indlela eqhutshwa yisimo sokusebenzisa ukuqhathanisaimodyuli yekhameraUbubanzi be-FOV—esikhundleni sokufaka nje izinombolo, sizochaza ukuthi ama-FOV ahlukene enza kanjani ezimweni zangempela, yimaphi ama-tradeoff ababandakanya, nokuthi ungawafanisa kanjani nesicelo sakho esithile. Ekugcineni, uzokwazi ukudlula izinganekwane ezithi “okukhulu kungcono” noma “okuncane kubukhali” futhi wenze izinqumo ezisekelwa idatha yephrojekthi yakho, noma ngabe kuyizinto zikagesi zabathengi, ukuzenzakalela kwezimboni, noma ukugadwa.
Okokuqala: Yini Eqinisweni i-FOV, Futhi Kungani Ibhalela?
Ngaphambi kokungena ekuqhathanisweni, asicacise izinto eziyisisekelo. I-FOV ibhekisa ebangeni le-angular lesigameko ikhamera engayithatha, elinganiswa ngama-degree (°). Inqunywa izinto ezimbili ezibalulekile: ubude bokugxila belensi kanye nosayizi we-sensor yesithombe. Ubude bokugxila obufushane noma i-sensor enkulu izobangela i-FOV ebanzi, kuyilapho ubude bokugxila obude noma i-sensor encane inciphisa i-FOV.
Kungani lokhu kubalulekile? I-FOV ithinta ngqo izici ezintathu ezibalulekile zokuthwebula izithombe:
• Ukubuka Indawo: Izindawo ezibanzi zithwebula okuningi endaweni ezungezile (kuhle kakhulu ezithombeni zeqembu noma ukuqapha izindawo ezinkulu), kanti izindawo ezincane zigxila emininingwaneni ethile (ilungile kakhulu ezintweni ezikude njengezilwane zasendle noma ukuskena amabhakhodi).
• Umbono & Ukuhlanekezela: Izindawo ezibanzi kakhulu zingadala ukuhlanekezela kwe-barrel (ukugoba imigqa eqondile emaphethelweni), kanti izindawo ezincane zinokuhlanekezela okuncane kodwa zingenza izinto zibukeke zikude kakhulu.
• Isinqumo Sesithombe & Imininingwane: Njengoba amaphikiseli enzwa asatshalaliswe kulo lonke i-FOV, izindawo ezibanzi zinganciphisa ukuminyana kwamaphikiseli (futhi ngaleyo ndlela imininingwane) ezindaweni ezithile, kanti izindawo ezincane zigxilisa amaphikiseli endaweni encane, zithuthukisa imininingwane ezintweni ezikude.
Manje, asiqhathanise ububanzi be-FOV ezimweni ezivame kakhulu, sigqamise ububanzi obufanele, izinzuzo, ukungalungi, kanye neziphakamiso zempela.
1. Ama-Smartphones Abathengi: Ukuhambisana Okuguquguqukayo Okusetshenziswa Hla.
Ama-Smartphones angamadivayisi wokuthwebula anezinhlobonhlobo eziningi, ngakho-ke amamojuli ekhamera yawo (avame ukuba nezinhlobonhlobo zamalensi) adinga ukumboza ububanzi obubanzi be-FOV ukuze abambe ama-selfie, izithombe, izindawo, kanye nezithombe eziseduze. Asihlukanise ububanzi obujwayelekile be-FOV nezimo zokusetshenziswa kwawo:
Uhlobo Lwelensi | Ububanzi Be-FOV | Isimo Esikhulu Sokusebenzisa | Izinto Ezinhle | Izinto Ezimbi |
