Uburebure bwibanze ni ikintu gikomeye kigereranya urwego rwo guhuza cyangwa gutandukanya imirasire yumucyo muri sisitemu ya optique. Iyi parameter igira uruhare runini muguhitamo uko ishusho ikorwa nubwiza bwiyo shusho. Iyo imirasire ibangikanye inyuze mumurongo wibanda kumurongo, bahurira kumurongo wibanze, bisobanurwa nkintera kuva optique hagati ya lens kugeza kuriyi ngingo. Ingingo yibanze niho imirasire yumucyo ihurira nyuma yo kunyura mumurongo, ikora ishusho ityaye. Kugirango ugere ku ishusho ityaye yikintu kitagira iherezo, lens igomba guhagarara kure yindege yibanze. Iri hindurwa risobanura impamvu lens nyinshi zaguka muburebure mugihe impeta yibanze izunguruka, bigatuma habaho kwibanda kubintu bya kure.
Mubikoresho bya optique, umurima wo kureba inguni (FOV) bivuga intera inguni yibintu bigaragara byafashwe na lens, hamwe na lens ikora nk'isonga ry'iyi mfuruka. Inguni ya FOV ningirakamaro kuko igena urugero rwahantu hagaragara. Inguni nini ya FOV itanga ibisubizo mugari wo kureba, ifata byinshi mubidukikije ariko hamwe no gukuza hasi. Ibinyuranye, niba intego yibintu irenze iyi mfuruka, ntabwo izinjira byuzuye murwego rwo kureba, biganisha kumashusho atuzuye cyangwa agoretse. Kurugero, mumafoto yinyamanswa, FOV ifunganye irashobora gutuma ibice byinyamanswa cyangwa ibiyikikije, mugihe FOV yagutse ishobora gufata amakuru arambuye cyane, bikagabanya umwanya wingenzi.
Mubihe bisanzwe, inguni ya FOV hamwe nuburebure bwerekanwe biringaniye. Iyi sano isobanura ko uburebure burebure bwibanze buhuye ninguni nini ya FOV, mugihe uburebure burebure bwibisubizo bivamo inguni ntoya ya FOV. Lens ya terefone, ifite uburebure burebure, nibyiza mugukurikirana kure no kurasa bisaba gufata ibintu bya kure muburyo burambuye. Izi lens zikoreshwa cyane mubikorwa bitandukanye nkumutekano wumujyi, imicungire yumuhanda, kugenzura imipaka no kurinda inkombe, gufotora ibinyabuzima, hamwe nibyangombwa bya siporo. Kurugero, lens ya terefone yateguwe kandi yakozwe na Jinyuan Optics, ifite uburebure buri hagati ya 30-120mm, 5-50mm, na 10-50mm, irashobora kuzuza ibyo bisabwa. Izi lens zitanga imikorere myiza mugutwara amashusho arambuye yibintu bya kure, bigatuma iba ibikoresho byingirakamaro kubanyamwuga muriyi nzego. Byongeye kandi, Jinyuan Optics itanga linzira ntoya ifite uburebure burebure, nka 1 / 2.7 "3MP 50mm na 1 / 1.8" 5MP 25mm, ihuza igishushanyo mbonera hamwe nubushobozi bukomeye bwo gufata amashusho.
Ibinyuranye, intumbero ngufi-yibanze, izwi kandi nka rugari-ngari, itanga umurongo mugari wo kureba kubera impande nini za FOV. Ibi biranga bituma bakwiriye cyane cyane kugenzura ahantu hanini hatagira ahantu hatabona, nko kurinda umutekano mukibanza, ububiko, ibibuga byindege, na sitasiyo. Inzira ngari irashobora gufata amashusho yagutse, ikemeza neza ahantu hakurikiranwa. Jinyuan Optoelectronics 'iheruka ya 1 / 2,5-inimero, 1.8mm z'uburebure bugufi-yibanze irerekana umurongo mugari wo kureba, hejuru ya pigiseli ndende, hamwe n'ibiranga amazi, hamwe hamwe bigira uruhare mubikorwa byayo byiza. Umwanya mugari wo kureba utuma lens ifata ahantu hanini murwego rumwe, mugihe pigiseli ndende iremeza ko ibisobanuro bisobanutse kandi bisobanuwe neza. Igishushanyo kitagira amazi gituma gikoreshwa hanze, ndetse no mubihe bibi. Nkigisubizo, iyi lens ikoreshwa cyane mumashusho yumuryango, sisitemu yo kugenzura umutekano, hamwe na kamera yimodoka, itanga ibisubizo byizewe kandi byujuje ubuziranenge byerekana amashusho kubikorwa bitandukanye.
Muncamake, uburebure bwibanze hamwe na FOV inguni nibintu bibiri byingenzi bigira ingaruka zikomeye kumikorere ya sisitemu optique. Gusobanukirwa umubano wabo no guhitamo ubwoko bwa lens bukwiye bushingiye kubikenewe byihariye birashobora kuzamura cyane imikorere yimashusho no gukurikirana mubikorwa bitandukanye. Yaba ifata ibintu bya kure hamwe nibisobanuro birambuye cyangwa kugenzura ahantu hanini, guhitamo neza lens birashobora gukora itandukaniro ryose mugushikira ibisubizo byiza.
