Icyuma cyerekana imashini ni iki?
A imashini yerekana imashinini ikintu gikomeye muri sisitemu yo kureba imashini, ikoreshwa kenshi mubikorwa, gukora robo, no kugenzura inganda. Lens ifasha gufata amashusho, guhindura urumuri rwumucyo muburyo bwa sisitemu sisitemu ishobora kumva no gutunganya. Ubwiza nibiranga lens birashobora kugira ingaruka cyane kubushobozi bwa sisitemu yo kumenya neza, gupima, cyangwa kugenzura ibintu.
Niki ubwoko bwimashini zerekana?
Ubwoko bumwebumwe busanzwe bwa mashini yerekanwe harimo:
1.Uburebure bwerekanwe bwibanze: Izi lens zifite uburebure bwibanze kandi butanga ubunini buhoraho bwo gufata amashusho yibintu ku ntera yihariye ya lens. Birakwiriye kubisabwa aho intera ikora nubunini bwibintu biguma bihoraho.
2.Icyerekezo kinini:Lens zoom zitanga uburebure bushobora guhinduka, butuma abakoresha bahindura umurima wo kureba no gukuza nkuko bisabwa. Zitanga guhinduka mugufata amashusho yibintu ahantu hatandukanye.
3.Ibikoresho bya terefegitura:Lens ya terefegitura yagenewe kubyara imirasire ibangikanye yumucyo, bivuze ko imirasire yingenzi itandukanijwe na sensor sensor. Ibi biranga ibisubizo mubipimo nyabyo kandi bihoraho bipima ibipimo byibintu, bigatuma bikwiranye no gupima neza.
4.Inzira ngari: Lens-angle lens ifite uburebure bugufi hamwe nuburebure bwagutse bwo kureba, bigatuma biba ingirakamaro mubisabwa bisaba gufata amashusho yibice binini cyangwa amashusho.
Mugihe uhisemo imashini yerekana imashini, ibintu ugomba gusuzuma harimo intera yifuzwa yakazi, umurima wo kureba, gukemura, ubwiza bwibishusho, guhuza lens guhuza, hamwe nibisabwa byihariye bya porogaramu.
Nibihe bintu biranga imashini yerekanwes?
Ibiranga imashini yerekwa imashini irashobora gutandukana bitewe nuruganda rukora na moderi yihariye. Ariko, bimwe mubisanzwe biranga imashini yerekana imashini zirimo:
1.Ibikoresho byo hejuru-optique:Imashini yerekana imashini yashizweho kugirango itange amashusho asobanutse kandi atyaye, akenshi ahuye nubushobozi bwo gukemura bwa kamera-nini cyane.
2.Kugoreka gato: Lens hamwe no kugoreka gake yemeza ko ishusho yafashwe ari ukuri kandi itagabanijwe, cyane cyane kubisabwa bisaba gupima neza cyangwa kugenzura.
3.Umuhanda ugaragara:Imashini zimwe zerekana imashini zagenewe gukorana nuburebure butandukanye bwumucyo, byemerera porogaramu zikoresha urumuri rugaragara, urumuri ultraviolet (UV), urumuri rwa infragre (IR), cyangwa amashusho menshi.
4.Ibihinduka kandi byoroshye: Lens zimwe na zimwe, nka zoom zoom, zitanga uburebure bwerekanwa hamwe nuburebure bwo kureba, butanga ubushobozi bwo gufata amashusho murwego rwo hejuru no gutandukanya ibintu.
5.Itumanaho: Lens ya telecentric itanga imirasire yumucyo ibangikanye, bikavamo gukuza no gupima neza ibipimo byibintu, tutitaye ku ntera yikintu.
6. Guhindura ibitekerezo: Imashini iyerekwa akenshi itanga intoki cyangwa moteri yibanda kumurongo, bituma abayikoresha bahindura ishusho kumurongo kubintu bitandukanye.
7.Ibishushanyo mbonera kandi byoroheje: Imashini yerekana imashini isanzwe igenewe kuba yoroheje kandi yoroheje, bigatuma ikwiranye na sisitemu yo kureba no kugabanya ikirenge muri rusange.
8.Umubare uhuza: Imashini yerekana imashini iraboneka hamwe na lens zitandukanye (nka C-mount, F-mount, M42, nibindi), byemeza guhuza kamera nini cyangwa kamera.
9.Ibidukikije biramba: Imashini zimwe zo kureba zashizweho kugirango zihangane n’ibidukikije bikaze mu nganda, hamwe n’imiterere nkimiturire ikomeye, itangiza umukungugu, hamwe no kurwanya ibinyeganyega cyangwa ubushyuhe butandukanye.
10.Ibikorwa-byiza: Imashini yerekanisha imashini akenshi igamije gutanga ibisubizo byingirakamaro kubishusho byerekana amashusho, bikerekana uburinganire hagati yimikorere nubushobozi buke.
Ni ngombwa gusuzuma ibisabwa byihariye bya porogaramu ya mashini yawe hanyuma ugahitamo ibiranga lens bihuye neza nibyo ukeneye.
