Muva nje, ukulungiswa kwamakhamera omakhalekhukhwini kuye kwanda ngesivinini esimangalisayo, futhi i-Samsung ngokuqinisekile ayihlukile kulokhu. Mhlawumbe abanye benu abanikazi abanenhlanhla bezingcingo ezihamba phambili zomkhiqizi waseKorea bayazibuza: Kungani ifoni yami inama-megapixel angu-100 noma ngaphezulu, kodwa ithatha izithombe ezingu-12Mpx kuphela? Ingabe iluphu? Sizokukhombisa ukuthi ungayishintsha kanjani i-Samsung S22 Ultra yakho, kodwa inqubo efanayo ingasetshenziswa kumodi ye-S23 Ultra, iye ku-108 Mpx ukuze uthathe izithombe ezinesinqumo esigcwele, futhi sizothinta nokuthi kungani kungeke kukufanele. it ezimweni eziningi.
Njengoba kushiwo esingenisweni, izibalo zamamegapixel zamafoni ahamba phambili zikhuphuke zaba ngamakhulu, nge-Samsung. Galaxy Mayelana nalokhu, i-S23 Ultra ifinyelele ku-200 Mpx ngekhamera eyinhloko, kodwa ezilungiselelweni ezizenzakalelayo ithatha kuphela izithombe ezingu-12,5 Mpx, ezifana ne-Samsung. Galaxy I-S22 Ultra inesinqumo esingu-108 Mpx, kodwa imiphumela ingu-12 Mpx. Kodwa kungani kunjalo, futhi angawani wonke ama-megapixel, lapho amakhamera esathatha izithombe ezinosayizi omaphakathi?
Ungaba nentshisekelo ku
Ukuze uphendule le mibuzo, ezinye izici zokusebenza zidinga ukucaciswa. Okokuqala, izinzwa zekhamera yedijithali zimbozwe izinkulungwane nezinkulungwane zezinzwa zokukhanya ezincane, okungukuthi amaphikseli, futhi ukulungiswa okuphezulu kusho amaphikseli engeziwe. Lokhu kungakhuluma ngoba uma sino-22 Mpx ku-S108 Ultra kuzoba yinto emangalisayo futhi nakuba kuyiqiniso ukuthi okuphumayo kule divayisi kuhlaba umxhwele ngempela, akuyona inombolo kuphela kodwa nosayizi wamaphikseli ngamanye. ekudlaleni. Uma ukwazi ukulingana endaweni efanayo yezinzwa zomzimba, lapho kufanele kube kuncane ngokunengqondo, futhi njengoba amaphikseli amancane enendawo encane, awakwazi ukuqoqa ukukhanya okuningi njengamaphikseli amakhulu, okuholela ekusebenzeni okuncane kokukhanya okuphansi. Futhi amakhamera omakhalekhukhwini ama-megapixel aphezulu azama ukuzungeza le nkinga ngento ebizwa nge-pixel binning.

Kalula nje, lobu buchwepheshe buhlanganisa amaphikseli ngamanye abe ngamaqembu, okwandisa ikhono lawo lokuthwebula idatha yokukhanya eyanele ukuze inzwa iqoqe lapho inkinobho yokuvala icindezelwa. Nini Galaxy I-S22 Ultra ingamaqembu amaphikseli angu-9, ngakho sifika ku-12 Mpx ngokuhlukanisa okulula - 108 Mpx ÷ 9 = 12 Mpx. Ngokungafani nezimbangi zayo eziningi, i-S22 Ultra ikunikeza amandla okuthatha izithombe ezinesinqumo esigcwele ngaphandle kokubopha usebenzisa uhlelo lokusebenza lwekhamera oluyisisekelo, futhi ukusetha i-S22 Ultra yakho ekudubuleni okunesinqumo esigcwele kuthatha nje ompompi ababili.
Ingabe kunengqondo ngempela?
Vele uvule uhlelo lokusebenza Lwekhamera, uthephe isithonjana se-aspect ratio kubha yamathuluzi ephezulu, bese ukhetha inketho engu-3:4 108MP. Yebo, kulula kanjalo. Umbuzo, noma kunjalo, uthi uma into efana nalena inengqondo ngempela. Okokuqala, kufanele kucatshangelwe ukuthi imiphumela ewumphumela izothatha ngokuphawulekayo isikhala sedatha esengeziwe. Okubaluleke nakakhulu, noma kunjalo, uzolahlekelwa ezinye izici ngemva kokushintsha, njengokufinyelela okulinganiselwe kwilensi ye-telephoto kanye nekhamera ye-angle ebanzi kakhulu, kodwa okubaluleke kakhulu, isithombe esiwumphumela singase singabukeki sisihle ngendlela obungayilindela. Uma unquma ukubuyela kuzilungiselelo zangempela ngemodi evamile yokudubula, thepha isithonjana se-aspect ratio futhi bese ukhetha inketho engu-3:4.

Uyazibuza ukuthi izithombe zihamba kanjani ngaphandle kokubopha? Izithombe ezilandelayo zibonisa umehluko ekusebenzeni ezimeni zokukhanya eziphansi ngempela ngokuvala nokuvula i-Samsung S22 Ultra. Kusethi ngayinye yesithombe, isithombe sokuqala besihlala sithathwa ngaphandle kwe-pixel binning kanti esesibili sathathwa nge-binning, lapho okuphumayo okungu-108Mpx kuye kwancishiswa kwaba ama-megapixel angu-12.
Ngezansi sibona ukuthuthuka okuthile kwikhwalithi yesithombe esithombeni sesibili esithathwe nge-pixel binning. Awukho umehluko omningi ngokomsindo, kodwa uma ubhekisisa, imigqa ichazwa kakhulu esithombeni sesibili. Amaphethelo esithombeni sokuqala abukeka emangelengele ngemva kokunqampuna, ikakhulukazi ekhoneni elingezansi kwesokudla. Kwenye isethi ethathwe endaweni emnyama kakhulu, isithombe sokuqala ngaphandle kwe-binning simnyama futhi sithola umsindo owengeziwe kunesithombe sesibili esine-binning. Yiqiniso, asikho isithombe esibukeka sisihle, kodwa kwakukhona ukuntuleka okuphawulekayo kokukhanya.

Kuyafana nangezinye izithombe, lapho esokuqala sihluke kakhulu kwesesibili. Eyokuqala, ethathwe ngokulungiswa okugcwele, ikhombisa umsindo owengeziwe kunalowo othathwe imizuzwana embalwa kamuva ngezilungiselelo zekhamera ezizenzakalelayo ze-S22 Ultra. Okuxakayo, ezithombeni ezimbili zokugcina kuma-megapixel angu-108, ingxenye yemininingwane ilahleka, lapho umbhalo othi "Nashville, Tennessee" ekhoneni elingezansi kwesokudla sephosta cishe awufundeki.

Cishe kuzo zonke izibonelo ezingenhla, isigameko sasimnyama kangangokuthi abantu abaningi bebengacabangi ngisho nokusithatha isithombe. Kodwa kuyathakazelisa ngempela ukuqhathanisa. I-Pixel binning eyezinzwa ezincane ngokomzimba zamakhamera anokucaca okuphezulu eza namafoni amaningi wesistimu. Android, kubalulekile ngoba kubasiza ukuthi babone ikakhulukazi izigcawu ezimnyama. Kuwukuyekethisa, isixazululo sizoncishiswa kakhulu, kodwa ukuzwela kokukhanya kuzokwanda. Inombolo ephezulu yama-megapixels nayo idlala indima, isibonelo, ekusondezeni isofthiwe lapho ushutha ividiyo nge-8K, okuyinikeza ukuguquguquka okwengeziwe, nakuba ukurekhoda kulokhu kulungiswa akukavamile neze.
Futhi kusho ukuthini lokho? Ukusetshenziswa kwe-pixel binning ukukhulisa ukuzwela kokukhanya kunengqondo, nakuba ukuphuma kokukhanya okuphansi kungehlukile kangako, okungenani ku-S22 Ultra. Ngakolunye uhlangothi, ukuthwebula isixazululo esigcwele se-Ultra esingu-108-megapixel ngokuvamile akukhiphi imininingwane eminingi esebenzisekayo esigcawini, ngokuvamile ngisho nasezimeni ezingcono zokukhanyisa. Ngakho ukushiya ukulungiswa kwefoni okungu-12Mpx kuletha umuzwa ongcono ezimweni eziningi.
