Adam Kos Kwakungu-2016 futhi i-Apple yethula i-iPhone 6S. Njengenye yezinto ezintsha eziqanjiwe, ulethe ukwanda kwama-megapixel ekhamera yakhe, ku-12 MPx. Futhi njengoba kwaziwa, lesi sinqumo sibuye sigcinwe uchungechunge lwamanje, okungukuthi i-iPhone 13 ne-13 Pro. Kodwa kungani lokhu kunjalo lapho umncintiswano unikeza ngisho nangaphezu kwe-100 MPx?
Abangazi bangacabanga ukuthi i-Samsung Galaxy S21 Ultra ene-108 MPx yayo kufanele iwashaye ngokuphelele ama-iPhone. Nokho, uma kuziwa kwikhwalithi yekhamera, okuningi akungcono. Nokho, okungenani mayelana ne-MPx. Kalula nje, ama-megapixel awabalulekile lapha, kodwa ikhwalithi (nosayizi) wenzwa. Inombolo ye-MPx empeleni iyiqhinga lokumaketha.
Imayelana nosayizi wenzwa, hhayi inombolo ye-MPx
Kodwa ukuze kube nobulungisa, yebo, ngokuqinisekile inombolo yabo ithinta umphumela ngezinga elithile, kodwa ubukhulu kanye nekhwalithi yenzwa kubaluleke kakhulu. Inhlanganisela yenzwa enkulu enenombolo ephansi ye-MPX empeleni ilungile ngokuphelele. Ngakho i-Apple ilandela indlela egcina inani lamaphikseli, kodwa ikhulisa njalo inzwa, futhi ngaleyo ndlela ubukhulu bephikseli ngayinye.
Igalari yezithombe
Ngakho yikuphi okungcono? Iba no-108 MPx lapho iphikseli ngayinye ingu-0,8µm ngosayizi (ikesi le-Samsung) noma ibe no-12 MPx lapho iphikseli ngayinye ingu-1,9µm ngosayizi (ikesi le-Apple)? Uma i-pixel ibe nkulu, ithwala ulwazi olwengeziwe ngakho iphinde inikeze umphumela ongcono. Uma uthatha isithombe ku-Samsung Galaxy S21 Ultra ngekhamera yayo eyinhloko engu-108MP, ngeke ugcine unesithombe esingu-108MP. Ukuhlanganisa i-Pixel kusebenza lapha, okuholela ekutheni amaphikseli angu-4 ahlanganiswe abe yinye, ukuze ibe nkulu ekugcineni. Lo msebenzi ubizwa nge-Pixel Binning, futhi uhlinzekwa yi-Google Pixel 6. Kungani lokhu kunjalo? Yebo kumayelana nekhwalithi. Endabeni ye-Samsung, ungavula ukuthatha izithombe kuzilungiselelo ngokulungiswa okugcwele kwe-108MPx, kodwa ngeke ufune.
Kungaba njalo okuthakaselayo
Ukuqhathanisa okuzimele
Okuwukuphela kwenzuzo yenani elikhulu kangaka lamamegaphikiseli kungaba kakhulu ekusondezeni kwedijithali. AbakwaSamsung bethula amakhamera abo ukuze ukwazi ukuthatha izithombe zenyanga ngawo. Yebo, kunjalo, kodwa kusho ukuthini ukusondeza kwedijithali? Ukusikwa nje kwesithombe sokuqala. Uma sikhuluma ngokuqhathaniswa okuqondile kwezinhlobo zefoni ze-Samsung Galaxy S21 Ultra kanye ne-iPhone 13 Pro, bheka nje ukuthi zombili lezi zingcingo zibekwe kanjani ezingeni elizimele elidumile lekhwalithi yesithombe.

Lapha, i-iPhone 13 Pro inamaphuzu ayi-137 futhi isendaweni yesi-4. I-Samsung Galaxy S21 Ultra bese inamaphuzu angu-123 futhi isendaweni yama-24. Yebo, kunezinto eziningi ezibalulekile ezifakiwe ekuhloleni, njengokuqoshwa kwevidiyo, futhi ngokuqinisekile kumayelana nokususa iphutha lesofthiwe. Nokho, umphumela uyasho. Ngakho-ke inani le-MPx alimane nje linqume ezithombeni zeselula.
Kuyaqapheleka ukuthi i-Samsung ehluke ngokuphelele enesoftware engaqediwe ikalwe kuleso simo, futhi namuhla ikhwalithi yekhamera iphakeme kakhulu.
Futhi kuyadingeka ukwengeza ukuthi i-Apple ihluke ngokuphelele kumthombo ovulekile we-Android;)
Erm iOS :)
