Ni ikiIjisho rya FisheyeLensi ya fisheye ni ubwoko bwa lensi ya kamera yagenewe gukora ishusho yagutse y'ahantu runaka, ifite uburyo bwo kugoreka cyane kandi budasanzwe. Lensi ya fisheye ishobora gufata ahantu hanini cyane, akenshi kugeza kuri dogere 180 cyangwa zirenga, ibyo bigatuma umufotozi afata agace kanini cyane k'aho hantu mu ifoto imwe.

Ijisho rya fisheye

Indorerwamo za Fisheye zitwa bitewe n’ingaruka zazo zidasanzwe zo guhindagurika, zikora ishusho y’uruziga cyangwa imeze nk’umugozi ishobora gukabya kandi igashyirwa mu buryo bugaragara. Ingaruka zo guhindagurika ziterwa n’uburyo indorerwamo ihindura urumuri iyo inyuze mu bice by’ikirahure bizinze bya lens. Iyi ngaruka ishobora gukoreshwa n’abafotora mu buryo bw’ubuhanga kugira ngo bakore amashusho yihariye kandi ahindagurika, ariko ishobora no kuba imbogamizi niba wifuza ishusho isa n’iy’umwimerere.

Indorerwamo za fisheye zigira ubwoko butandukanye, harimo indorerwamo za fisheye zigira uruziga, indorerwamo za fisheye zifite uruziga rurerure, n'indorerwamo za fisheye zifite imiterere yazo yihariye kandi zikwiriye ubwoko butandukanye bwo gufotora.

Bitandukanye n'indorerwamo zo mu bwoko bwa rectilinear,indorerwamo z'amaso y'ifiNtabwo bigaragazwa neza n'uburebure bw'inyuma n'ubuso bwonyine. Inguni yo kureba, umurambararo w'ishusho, ubwoko bw'icyerekezo, n'uburyo bwo gupima ibintu byose bitandukanye ukurikije ibi.

Ubwoko bw'ikoreshwa ry'imiterere

Indorerwamo z'amaso y'ifi zizengurutse

Ubwoko bwa mbere bw'ama-lenses y'ifi yakozwe ni ama-lenses "azengurutse" ashobora gukora ishusho izengurutse ifite aho ireberera dogere 180. Afite uburebure bugufi cyane, ubusanzwe buri hagati ya mm 7 na mm 10, butuma abasha gufata ishusho yagutse cyane y'aho hantu.

Ikirahuri cy'amaso y'uruziga

Indorerwamo z'amaso zizunguruka zagenewe gukora ishusho y'uruziga ku gice cy'ishusho cya kamera cyangwa icyuma gifata amashusho. Ibi bivuze ko ishusho ivuyemo ifite ishusho y'uruziga ifite imipaka y'umukara ikikije agace k'uruziga, bigatuma habaho ingaruka zidasanzwe z' "igikombe cy'ifi". Inguni z'ishusho y'amaso zizunguruka ziba umukara rwose. Ubu bwijime butandukanye no guhindagurika buhoro buhoro kw'indorerwamo zizunguruka kandi zigatangira gutya. Ishusho y'uruziga ishobora gukoreshwa mu gukora ibihangano bishimishije kandi bihanga. Ibi bifite inguni igororotse, itambitse kandi igororotse. Ariko bishobora kandi kuba imbogamizi niba umufotozi ashaka ikigereranyo cy'urukiramende.

Izengurukaindorerwamo z'amaso y'ifizikoreshwa mu gufotora mu buryo bw'ubuhanzi n'ubugeni, nko mu gufotora mu bwubatsi, gufotora mu buryo bw'incamake, no gufotora mu mikino ikomeye. Zishobora kandi gukoreshwa mu bikorwa bya siyansi na tekiniki aho bikenewe kureba mu mfuruka nini, nko mu bumenyi bw'ikirere cyangwa mikorosikopi.

Indorerwamo z'amaso y'ifi (zizwi nka 'fish-eye' cyangwa 'rectangular')

Uko lenzi za fisheye zagendaga zikundwa mu gufotora muri rusange, amasosiyete acuruza kamera yatangiye gukora lenzi za fisheye zifite ishusho nini kugira ngo zitwikire icyuma cyose cy’urukiramende. Zitwa fisheyes zigororotse, cyangwa rimwe na rimwe “zifite urukiramende” cyangwa “zifite uruhande rwuzuye”.

Indorerwamo z'amafi za diagonal ni ubwoko bwa lens y'amafi ya fisheye ishobora gukora ishusho y'inyuma cyane y'ahantu hari urwego rw'inyuma rwa dogere 180 kugeza 190, mu gihe inguni zitambitse n'izihagaze ziba nto. Izi lens zitanga ishusho idasobanutse neza kandi ikabije, ariko bitandukanye n'indorerwamo z'amafi za fisheye zizengurutse, zuzuza ishusho yose y'urukiramende rw'icyuma cya kamera cyangwa urwego rwa filime. Kugira ngo ubone ingaruka zimwe kuri kamera za digitale zifite sensors nto, hakenewe uburebure bugufi bw'ifatizo.

Ingaruka zo kugoreka kw'umurongo ugororotseindorerwamo y'amaso y'ifiIrema isura idasanzwe kandi ikomeye ishobora gukoreshwa n'abafotozi mu buryo bw'ubuhanga kugira ngo ifate amashusho agezweho kandi akurura amaso. Ishusho ikabije ishobora gutuma umuntu yumva ubwinshi n'ingendo mu gice, kandi ishobora no gukoreshwa mu guhanga ibihangano bidasanzwe kandi bidasanzwe.

Ijisho ry'ifi rifite ishusho y'umurambararo

Indorerwamo z'amaso y'ifi zishushanyijeho cyangwa zikozwe mu ruziga

Uruziga rwaciweindorerwamo z'amaso y'ifiHari ubundi bwoko bwa lenzi y'amaso y'ifi buhari, hiyongereyeho lenzi y'ifi y'uruziga n'inziga yuzuye navuze mbere. Hagati y'ifi y'uruziga n'inziga igizwe n'ishusho y'uruziga yagenewe ubugari bwa filime aho kuba uburebure. Kubera iyo mpamvu, ku buryo ubwo aribwo bwose bwa filime butari kare, ishusho y'uruziga izacibwa hejuru no hepfo, ariko igakomeza kwerekana impande z'umukara ibumoso n'iburyo. Ubu buryo bwitwa "ifoto" ya fishye.

Ijisho ry'ifi rifite uruziga rugufi

Izi lenzi ubusanzwe zigira uburebure bwa mm 10-13 n'aho zireberwa na dogere 180 kuri kamera ikoresha icyuma gipima.

Indorerwamo za fisheye zikozwe mu ruziga ni amahitamo ahendutse ugereranyije n'indorerwamo za fisheye zuzuye, kandi zitanga ishusho yihariye ifite ingaruka zo kuzunguruka.

Indorerwamo ntoya z'amaso y'ifi

Kamera ntoya zo kuri interineti, cyane cyane iyo zikoreshwa nk'amakamera y'umutekano, akenshi ziba zifite amakamera y'ubudozi kugira ngo zirusheho gukwirakwira. Amakamera magufi ya fisheye, nka M12 fisheye lens na M8 fisheye lens, yagenewe amafoto y'amakamera magufi akoreshwa muri kamera z'umutekano. Ingano z'imiterere y'amakamera y'ubudozi bw'amashusho zizwi cyane zikoreshwa zirimo 1⁄4″, 1⁄3″, na 1⁄2″. Bitewe n'agace gakora k'amakamera y'amashusho, lens imwe ishobora gukora ishusho izengurutse kuri sensor nini y'amashusho (urugero 1⁄2″), n'agace kuzuye ku gasanduku gato (urugero 1⁄4″).
