A ilensi yokuskena umgcayilensi ekhethekileyo esetyenziswa kakhulu kwiikhamera zokuskena ezilandelelanayo. Yenza imifanekiso yokuskena ngesantya esiphezulu ngobukhulu obuthile. Yahlukile kwiilensi zekhamera zemveli kwaye idla ngokusetyenziswa kwicandelo lemizi-mveliso.
Yintoni umgaqo osebenzayo wokuskena umgcailensi?
Umgaqo osebenzayo welensi yokuskena umgca usekelwe kakhulu kubuchwepheshe bokuskena umgca. Xa isebenza, ilensi yokuskena umgca iskena umphezulu wesampulu umgca ngomgca kwaye iqokelele ulwazi lokukhanya komqolo ngamnye weepikseli ukunceda ilensi yokuskena umgca ibambe umfanekiso wesampulu yonke endaweni yokuthatha umfanekiso wonke ngaxeshanye.
Ngokukodwa, umgaqo wokusebenza kwelensi yokuskena umgca uqulathe amanyathelo aliqela:
Imifanekiso ye-Optical:Isignali yokukhanya yesampulu eza kuskenwa ibanjwa zizinto ezibonisa ukukhanya komgca ngomgca kwilensi yokuskena yomgca kwaye iguqulwe ibe ziisignali zombane.
Ukuskena komgca ngomgca:I-photosensitive element ehambelana nomgca ngamnye iskena ukusuka phezulu ukuya ezantsi kwesampuli ngesantya esithile, iguqula ulwazi lokukhanya lomgca ngamnye lube yisignali yombane.
Ukucubungula isignali:Emva kokucubungula, isignali yombane iguqulwa ibe sisignali yedijithali yokwenza umfanekiso.
Ukuthunga umfanekiso:thunga kunye imiqondiso yedijithali yomqolo ngamnye ukuze ekugqibeleni wenze umfanekiso wesampulu yonke.
Umgaqo wokusebenza kwelensi yokuskena umgca
Zeziphi iiparameter ekufuneka ziqwalaselwe kwiilensi zokuskena umgca?
Iiparameters zeiilensi zokuskena umgcazinxulumene kakhulu neemfuno ezahlukeneyo kunye neemeko zokusetyenziswa. Ezi parameter zilandelayo kufuneka zigxile kuzo:
Isisombululo
Isisombululo selensi yokuskena umgca sidla ngokuba sisisombululo esiphambili. Okukhona isisombululo siphezulu, kokukhona ukucaca komfanekiso kuphezulu, okunxulumene nenani leepikseli kwindawo yokufota kunye nobukhulu bento yokufota.
Imbobo
Ubungakanani bomngxuma bulawula ubungakanani bokukhanya okungena kwilensi, nto leyo echaphazela ukukhanya komfanekiso welensi kunye nexesha lokuvezwa kwefilimu. Umngxuma omkhulu unokuphucula umgangatho womfanekiso xa usetyenziswa kwiimeko zokukhanya okuphantsi, kodwa unokunciphisa ububanzi bobunzulu.
Uluhlu lokugxila
Uluhlu lokugxila lubhekisa kumgama onokuthi uthathwe yilensi. Ngokubanzi, okukhona ibanzi, kokukhona ingcono, kwaye ibanzi kuthetha ukuba inokudubula izinto ezininzi ezinobude obahlukeneyo befocal.
Ukuphakama komfanekiso
Ukuphakama komfanekiso kubhekisa kubude bendawo yokufota ilensi kwicala lokuskena. Ukuphakama komfanekiso omkhulu kufuna isantya esikhawulezayo sokuskena, nto leyo eya kubangela isantya esiphezulu sokufota kunye nesantya esiphezulu sokudlulisa idatha.
Gxila kumgangatho womfanekiso
Iumgangatho womlingo
Umgangatho womfanekiso ungalinganiswa ngeeparameters ezifana nesisombululo esisecaleni, umlinganiselo wesignali-kwingxolo, kunye nokugcwala kombala. Ngokwesiqhelo, isisombululo esiphezulu esisecaleni, umlinganiselo wesignali-kwingxolo, kunye nokugcwala kombala kuthetha umgangatho ophezulu womfanekiso.
Ubungakanani kunye nobunzima belensi
Ubungakanani kunye nobunzima bunokuchaphazela ukusetyenziswaiilensi zokuskena umgcakwezinye iinkqubo. Ke ngoko, ubungakanani kunye nobunzima belensi kufuneka buqwalaselwe ngokweemeko ezahlukeneyo zokusetyenziswa.
Iingcinga Zokugqibela:
Ukuba unomdla wokuthenga iintlobo ngeentlobo zeelensi zokujonga, ukuskena, iidrone, ikhaya elikrelekrele, okanye naluphi na olunye uhlobo lokusetyenziswa, sinazo izinto ozifunayo. Nxibelelana nathi namhlanje ukuze ufunde okungakumbi ngeelensi zethu kunye nezinye izixhobo.
