Yintoni esetyenziswayoiskenaingiilensi? Ilensi yokuskena isetyenziselwa kakhulu ukuthwebula imifanekiso kunye nokuskena okubonakalayo. Njengenye yezona zinto ziphambili zesiskena, ilensi yesiskena inoxanduva lokuthwebula imifanekiso nokuyiguqula ibe ziimpawu ze-elektroniki.
Inoxanduva lokuguqula iifayile zokuqala, iifoto, okanye amaxwebhu abe ziifayile zemifanekiso yedijithali, okwenza kube lula kubasebenzisi ukugcina, ukuhlela, kunye nokwabelana ngazo kwiikhompyutha okanye kwezinye izixhobo zedijithali.
Zithini iiskeniingizinto zelensi?
Ilensi yokuskena yenziwe ngamacandelo ahlukeneyo, aqinisekisa ukuba ukuskena kungathatha imifanekiso ecacileyo nechanekileyo:
Ilensi
Ilensi yeyona nto iphambili kwi-ilensi yokuskena, isetyenziselwa ukujolisa ukukhanya. Ngokulungisa indawo yeelensi okanye ukusebenzisa iilensi ezahlukeneyo, ubude befocal kunye ne-aperture zingatshintshwa ukuze kufezekiswe iziphumo ezahlukeneyo zokudubula.
Ilensi yokuskena
Imbobo
I-Aperture yi-aperture elawulekayo esembindini welensi, esetyenziselwa ukulawula ubungakanani bokukhanya okungena kwilensi. Ukulungisa ubungakanani be-aperture kunokulawula ubunzulu bentsimi kunye nokukhanya kokukhanya okudlula kwilensi.
Findandatho ye-ocus
Indandatho yokugxila sisixhobo esijikelezayo esijikeleziswayo esisetyenziselwa ukulungisa ubude be-focal yelensi. Ngokujikelezisa indandatho yokugxila, ilensi ingahambelana nomntu ochaphazelekayo kwaye ifezekise ukugxila okucacileyo.
Aisenzi se-utofocus
Ezinye iilensi zokuskena zikwaxhotyiswe ngee-autofocus sensors. Ezi sensors zinokulinganisa umgama wento efotwayo kwaye zilungise ngokuzenzekelayo ubude be-focal yelensi ukuze kufezekiswe isiphumo esichanekileyo se-autofocus.
Itekhnoloji yokulwa nokungcangcazela
Abanye baphambiliiilensi zokuskenaisenokuba neteknoloji yokulwa nokushukuma. Le teknoloji inciphisa ukufiphala komfanekiso okubangelwa kukushukuma ngesandla ngokusebenzisa iziqinisi okanye izixhobo zoomatshini.
Indlela yokucoca iskenaingilensi?
Ukucoca ilensi yokuskena nako ngumsebenzi obalulekileyo, kwaye ukucoca ilensi linyathelo elibalulekileyo ekugcineni ukusebenza kwayo kunye nomgangatho womfanekiso. Kufuneka kuqatshelwe ukuba ukucoca ilensi yokuskena kufuna unonophelo olukhulu ukuthintela umonakalo kumphezulu welensi. Kungcono ukucoca ilensi yingcali okanye ubuze iingcebiso zayo.
Ilensi yokuskena
Ukucoca ilensi yokuskena ngokubanzi kubandakanya la manyathelo alandelayo:
1.Amanyathelo okulungiselela
1) Cima iskena phambi kokuba ucoce. Ngaphambi kokuba ucoce, nceda uqinisekise ukuba iskena icinyiwe kwaye ayifakwanga kumbane ukuze uphephe naziphi na iingozi zombane.
2) Khetha izixhobo zokucoca ezifanelekileyo. Nika ingqalelo ekukhetheni izixhobo ezenzelwe ngokukodwa ukucoca iilensi ze-optical, ezifana nephepha lokucoca iilensi, ii-ejectors zebhaluni, iipeni zeelensi, njl. Kuphephe ukusebenzisa iitawuli zephepha eziqhelekileyo okanye iitawuli kuba zinokukrwela umphezulu welensi.
2.Ukusebenzisa i-ejector yebhaluni ukususa uthuli kunye nokungcola
Okokuqala, sebenzisa i-ejector yebhaluni ukuze ukhuphe uthuli kunye nokungcola okuphuma kumphezulu welensi kancinci, uqinisekise ukuba kusetyenziswa i-ejector ecocekileyo ukuze kuthintelwe ukongeza uthuli olungakumbi.
3.Coca ngephepha lokucoca ilensi
Songa okanye ugobe iphepha elincinci lokucoca ilensi kancinci, uze ulishukumise kancinci phezu kwelensi, uqaphele ukuba ungacinezeli okanye ukrwele umphezulu welensi ngamandla. Ukuba kukho amabala aqinileyo, ungaphosa ithontsi elinye okanye amabini esisombululo sokucoca ilensi esikhethekileyo kwiphepha lokucoca.
4.Nika ingqalelo ekucoceni kwicala elifanelekileyo
Xa usebenzisa iphepha lokucoca, qiniseka ukuba ulicoca kwicala elifanelekileyo. Ungalandela icala lokujikeleza ukusuka embindini ukuze ungashiyi amabala efayibha akrazukileyo okanye afipheleyo kwilensi.
5.Nika ingqalelo kwiziphumo zovavanyo emva kokugqiba ukucoca
Emva kokucoca, sebenzisa iglasi yokukhulisa okanye isixhobo sokubukela ikhamera ukujonga ukuba umphezulu welensi ucocekile kwaye awunazo iintsalela okanye amabala.
