Adam Kos Inombolo ye-MPx nobude be-zoom yokubona yilokho ongakubona ekuqaleni mayelana nokucaciswa kwekhamera. Kodwa kwabaningi, ukukhanya kwelensi kuzotshela okuningi. I-lens ye-periscopic inenzuzo enkulu yokuthi ifihliwe ngaphakathi komzimba wedivayisi, ngakho-ke ayenzi izimfuno ezinjalo kubukhulu be-optics. Kodwa futhi inesimo esisodwa sokungalungi, okuyikona kanye ukukhanya okungalungile.
I-Apple yazama ukulwa nomncintiswano wayo kwaze kwaba ngu-2015, lapho yethula i-iPhone 6S, okungukuthi i-iPhone yayo yokuqala enekhamera engu-12MPx. Futhi nakuba abanye bezama njalo ukwandisa leli nani, i-Apple yalandela ifilosofi yayo. Nakuba lokhu kungase kushintshe nge-iPhone 14 (ikhamera ene-angle ebanzi kulindeleke ukuthi ibe ngu-48 MPx), ngisho neminyaka eyisithupha ngemva kokwethulwa kwe-iPhone 6S, inkampani yethula uchungechunge lwe-iPhone 13, oluhlome ngokuphelele ngamakhamera ayi-12 MPx.

Izithombe zimayelana nokukhanya
I-Apple ayizange ikhulise isixazululo, futhi esikhundleni salokho yandise izinzwa ngokwazo namaphikseli azo, ngaleyo ndlela izuze izithombe ezingcono kakhulu ngezindleko zobukhulu bazo. Ngisho nenombolo yesikhala ngokwayo, esetshenziselwa ukubonisa ukukhanya, yayithuthuka. Inani lokukhanya linquma ukuthi kungakanani ukukhanya okuwela kunzwa. Ngakho lapho imbobo iphakeme (ngakho isibalo siphansi ngokwaso), kuyancipha ukumelana nokukhanya okudlula kulensi. Umphumela uba izithombe zekhwalithi engcono ezimeni eziphansi zokukhanya.
Futhi kulapho sifika khona enkingeni ngamalensi e-periscope. Yebo, ngokwesibonelo, into entsha yamanje esesimweni se-Samsung Galaxy S22 Ultra izohlinzeka ngokusondeza okungu-10x, noma i-iPhone 13 Pro ine-zoom engu-3x kuphela, kodwa futhi ine-aperture ye-f/4,9. Lokhu akusho lutho ngaphandle kokuthi uyisebenzisa kuphela ezimweni ezikahle zokukhanyisa. Njengoba ukukhanya kuncipha, ikhwalithi yomphumela izokwehla ngokushesha. Noma i-f/2,8 aperture ye-telephoto lens ye-iPhone 13 Pro ayilungile. Ngoba imiphumela izohlupheka kalula ngomsindo. Ikhamera ye-periscope isebenzisa uhlelo lwezibuko ze-prismatic kanye namalensi, lapho ukukhanya okufunayo "kulahleka" nje ngoba akubonakali nje ngamadigri angu-90, kodwa futhi kufanele kuhambe ibanga elide.
Igalari yezithombe
Ingabe siyoke sibone ukusondeza okukhulu kwe-optical?
Futhi njengoba nje u-Apple engakawakhiphi amafoni asongekayo okwamanje ngoba abakholelwa kubuchwepheshe, asinawo ngisho namalensi e-periscopic kuma-iPhone. Impendulo yombuzo othi kungani singenayo "i-periscope" ku-iPhone empeleni ilula. Ubuchwepheshe buyathakazelisa, kepha ukusetshenziswa kwabo kusabambezeleka. Futhi i-Apple imane ifuna ukuhlinzeka kuphela okungcono kakhulu ngangokunokwenzeka. Ngaphezu kwalokho, ukuthambekela ukuthi i-telephoto lens ayibalulekile kangako, yingakho futhi yengeza ilensi ye-angle ebanzi kakhulu ochungechungeni oluyisisekelo ngaphandle kwe-Pro epithet.
