Ilensi ye-telecentric luhlobo lweilensi yokukhanya, ekwaziwa ngokuba yilensi kamabonakude, okanye ilensi yetelephoto. Ngokusebenzisa uyilo lwelensi ekhethekileyo, ubude bayo obuphambili bude kakhulu, kwaye ubude belensi buhlala buncinci kunobude obuphambili. Uphawu kukuba inokumela izinto ezikude ezinkulu kunobukhulu bazo bokwenyani, ukuze ikwazi ukuthwebula indawo ekude ngokucacileyo nangokweenkcukacha.

Iilensi zeTelecentric zisetyenziswa kakhulu kwimiboniso efana nemidlalo, iifoto zezilwanyana zasendle kunye nendalo, kunye nokujonga izinto ngeenkwenkwezi, kuba le miboniso idla ngokufuna ukudubula okanye ukujonga izinto zikude.Iilensi zeTelecentricinokusondeza izinto ezikude “kufutshane” ngelixa igcina ukucaca neenkcukacha zomfanekiso.

Ukongeza, ngenxa yobude obude be-focal lens ze-telecentric, zinokufikelela kwi-background blur kunye nobunzulu obungaphantsi kwentsimi, okwenza loo nto ibonakale ngakumbi xa ifotwa, ngoko ke zisetyenziswa kakhulu kwi-portrait photography.

Ilensi ye-telecentric

1.Iimpawu eziphambili zeelensi ze-telecentric

Umgaqo osebenzayo welensi ye-telecentric kukusebenzisa isakhiwo sayo esikhethekileyo ukusasaza ukukhanya ngokulinganayo kunye nokubonisa umfanekiso kwi-sensor okanye ifilimu. Olu phawu luyivumela ukuba ifumane iziphumo ezingcono zokuthatha imifanekiso xa ithatha imifanekiso ekude nomntu ochaphazelekayo. Ngoko ke, zithini iimpawu zeelensi ze-telecentric?

Imifanekiso echanekileyo kakhulu:

Umfanekiso osemaphethelweniilensi ye-telecentricayizukugoba. Kwanakwicala lelensi, imigca isagcina i-engile efanayo yokuhlangana ne-axis esembindini yelensi, ngoko ke imifanekiso echanekileyo ingathathwa.

Ingqiqo enamandla enamacala amathathu:

Ngenxa ye-orthogonal projection, ilensi ye-telecentric inokugcina ubudlelwane obulinganayo bendawo, okwenza imifanekiso ebanjiweyo ibe nombono onamandla we-three-dimensional.

Imigca ehambelanayo:

Ngenxa yesakhiwo sangaphakathi esikhethekileyo se-optical, ilensi ye-telecentric inokugcina ukukhanya kungena kwilensi kuhambelana kuzo zonke iindawo, oko kuthetha ukuba imigca yomfanekiso ebanjwe yilensi iya kuhlala ithe tye ngaphandle kokugoba okanye ukujika.

2.Izicelo eziphambili zeelensi ze-telecentric

Iilensi zeTelecentric zisetyenziswa kakhulu kwezi ndawo zilandelayo:

Izicelo zokucubungula imifanekiso

Kwimimandla efana nokubona ngekhompyutha efuna ukucutshungulwa kwemifanekiso, iilensi ze-telecentric zisetyenziswa kakhulu ngenxa yeziphumo zazo zokufota ngokuchanekileyo, ezenza ukucutshungulwa kwemifanekiso kube ngokuchanekileyo ngakumbi.

Izicelo zovavanyo lwemizi-mveliso

Iilensi zeTelecentric zihlala zisetyenziswa kwezinye ii-index zemizi-mveliso ezifuna imifanekiso echanekileyo.

Isicelo sobungcali sokufotas

Kwimifanekiso ethile yobungcali,iilensi ze-telecentriczihlala zisetyenziswa, ezinje ngokufota ngoyilo lwezakhiwo, ukufota ngemveliso, njl.

Izicelo zokufota ngeenqwelo moya kunye neefoto zefowuni

Kwimifanekiso yeenqwelo-moya kunye ne-telephoto, iilensi ze-telecentric zinokufota imifanekiso ngobubanzi obuthathu kunye nokuchaneka okuphezulu, kwaye zisetyenziswa kakhulu.
