Kulezi zinsuku, akusajwayelekile ukuhlangana nama-smartphones ane-MPx engaphezu kwe-100. Ngokukhethekile, uhla lwama-smartphones akwa-Samsung ane-Ultra moniker selunekhamera engu-108MPx isikhathi eside manje. Ngaphezu kwalokho, amakhamera anesinqumo esiphezulu kangaka afinyelela esigabeni esiphakathi. Isib. I-Samsung ngokwayo ifake kuyo Galaxy A73. Kodwa-ke, lezi zingcingo zisathatha izithombe ze-12MP ngokuzenzakalelayo. Kodwa kungani kunjalo?
Liyini iphuzu lawo wonke lawo ma-megapixel uma amakhamera esathatha izithombe ezinosayizi omaphakathi? Akunzima kangako ukukuqonda. Izinzwa zekhamera yedijithali zimbozwe izinkulungwane nezinkulungwane zezinzwa zokukhanya ezincane, noma amaphikseli. Ukulungiswa okuphezulu kusho amaphikseli engeziwe kunzwa, futhi uma amaphikseli engeziwe alingana endaweni efanayo yenzwa, kufanele abe mancane lawa maphikseli. Ngenxa yokuthi amaphikseli amancane anendawo encane, awakwazi ukuqoqa ukukhanya okuningi njengamaphikseli amakhulu, okusho ukuthi enza kabi kakhulu ekukhanyeni okuphansi.

pixel binning
Kodwa amakhamera efoni ane-megapixel ephezulu ngokuvamile asebenzisa indlela ebizwa nge-pixel binning ukuze azungeze le nkinga. Kuwudaba lobuchwepheshe, kodwa okubalulekile ukuthi uma kwenzeka Galaxy I-S22 Ultra (futhi mhlawumbe ne-A73 ezayo) ihlanganisa amaqembu amaphikseli ayisishiyagalolunye. Isuka enanini elingu-108 MPx, izibalo ezilula ziphumela ku-12 MPx (108 ÷ 9 = 12). Lokhu akufani ne-Pixel 6 ye-Google, enezinzwa zekhamera ezingu-50MP ezihlala zithatha izithombe ezingu-12,5MP ngoba zihlanganisa amaphikseli amane kuphela. Galaxy Kodwa-ke, i-S22 Ultra iphinde ikunike amandla okuthatha izithombe ezinokulungiswa okugcwele ngokuqondile kuhlelo lokusebenza lwekhamera yesitoko.
Izithombe zesampula Galaxy I-S22 Ultra
I-Pixel binning ibalulekile kuzinzwa ezincane ngokomzimba zamakhamera anokucaca okuphezulu, njengoba lesi sici sizisiza ezigcawini ezimnyama. Kuwukuvumelana lapho ukulungiswa kuzokwehla, kodwa ukuzwela ekukhanyeni kuzokhula. Izibalo ezinkulu zama-megapixel zivumela futhi ukuguquguquka kwesoftware/ukusondeza kwedijithali nokuqoshwa kwevidiyo okungu-8K. Kodwa-ke futhi ngokwengxenye nje ukumaketha. Ikhamera engu-108MP ibukeka ihlaba umxhwele kakhulu ngokwemininingwane kunekhamera eyi-12MP, yize ifana ngokuphumelelayo isikhathi esiningi.
Ungaba nentshisekelo ku
Ngaphezu kwalokho, kubukeka sengathi naye uzonqotshwa yilokhu Apple. Kuze kube manje, ubelokhu elandela isu eliqinile le-MPx eyi-12 ngokukhuliswa njalo kwenzwa kanjalo namaphikseli ngamanye. Kodwa-ke, i-iPhone 14 kufanele ifike nekhamera engu-48 MPx, ezovele ihlanganise amaphikseli angu-4 ibe yinye futhi ngaleyo ndlela izithombe ezingu-12 MPx zizokwakhiwa futhi. Ngaphandle kwalapho ungumthwebuli zithombe ogxile kakhulu emsebenzini futhi ungafuni ukuphrinta izithombe zakho ngamafomethi amakhulu, kuhlale kufanelekile ukushiya ukuhlanganisa kuvuliwe futhi kushuthwe kumphumela ongu-12 MPx.
Akukona ukumaketha, ngokukhanya okuhle izithombe ezigcwele zinemininingwane eminingi futhi lokhu kusetshenziselwa ukusondeza (idijithali), ngokubonakalayo iqala ku-3x.
Ekukhanyeni okungcono, ithuthukisa isamba ngokugoqa.
Yebo, ukusondeza kwedijithali kufika ku-100x. Nokho, ukusetshenziswa kwayo kuyimpikiswano ngandlela thize.
I-100x idlulele impela, kodwa noma yini ephakathi kuka-1x no-3x ingcono kakhulu ekukhanyeni okuhle ngenxa yale nzwa enkulu ene-mpix eningi. Ngokukhanya okubi, inzuzo ayisekho...
