Mwina ena mwa inu eni ake omwe ali ndi mwayi wa mafoni apamwamba aku Korea akudabwa: Chifukwa chiyani foni yanga ili ndi ma megapixels 100 kapena kuposerapo, koma mumangotenga zithunzi za 12Mpx? Kodi ndi loop? Tikuwonetsani momwe mungasinthire Samsung S22 Ultra yanu, koma njira yomweyi ingagwiritsidwe ntchito pa S23 Ultra, kupita ku 108 Mpx mode kuti mujambule zithunzi zokhazikika, ndipo tikhudzanso chifukwa chake sizingakhale zofunikira. nthawi zambiri.
Monga tanenera kumayambiriro, chiwerengero cha megapixel cha mafoni abwino kwambiri chakwera mpaka mazana, ndi Samsung. Galaxy Pachifukwa ichi, S23 Ultra idafika mpaka 200 Mpx yokhala ndi kamera yayikulu, koma pazokhazikika zimangotenga zithunzi za 12,5 Mpx, zofanana ndi Samsung. Galaxy S22 Ultra ili ndi malingaliro a 108 Mpx, koma zotulukapo ndi 12 Mpx. Koma chifukwa chiyani zili choncho, ndipo ma megapixels onsewa ndi a chiyani, pomwe makamera amajambulabe zithunzi zazikuluzikulu?
Mutha kukhala ndi chidwi ndi
Kuti tiyankhe mafunsowa, mbali zina zogwirira ntchito ziyenera kufotokozedwa. Choyamba, masensa a kamera ya digito amaphimbidwa ndi masauzande ndi masauzande a masensa ang'onoang'ono, mwachitsanzo ma pixel, ndipo kusamvana kwakukulu kumatanthauza ma pixel ochulukirapo. Izi zingayankhulire chifukwa tikakhala ndi 22 Mpx pa S108 Ultra chidzakhala chinthu chodabwitsa ndipo ngakhale ndizowona kuti zotulutsa kuchokera ku chipangizochi ndizochititsa chidwi, si chiwerengero chokha komanso kukula kwa ma pixel omwe ali. pa play. Mukatha kukwanira pamalo amodzi a sensa yakuthupi, m'pamenenso iyenera kukhala yaying'ono, ndipo popeza ma pixel ang'onoang'ono amakhala ndi malo ang'onoang'ono, sangathe kusonkhanitsa kuwala kochuluka ngati ma pixel akulu, zomwe zimapangitsa kuti pakhale kuwala kocheperako. Ndipo makamera am'manja a megapixel apamwamba amayesa kuthana ndi vutoli ndi chinthu chotchedwa pixel binning.

Mwachidule, ukadaulo uwu umaphatikiza ma pixel omwe ali m'magulu, kukulitsa luso lawo lojambula deta yowala yokwanira kuti sensa isonkhanitse batani la shutter likakanikiza. Liti Galaxy S22 Ultra ndi magulu a ma pixel 9, kotero timafika ku 12 Mpx mwa magawo osavuta - 108 Mpx ÷ 9 = 12 Mpx.

Kodi zikumvekadi?
Ingotsegulani pulogalamu ya Kamera, dinani chizindikiro cha mawonekedwe pazida zapamwamba, kenako sankhani njira ya 3:4 108MP. Inde, ndizosavuta. Funso, komabe, ndilakuti, kapena m'malo ngati izi zili zomveka. Choyamba, ziyenera kuganiziridwa kuti zotsatira zake zidzatenga malo ochulukirapo a deta. Chofunika kwambiri, komabe, mudzataya zinthu zina mukasintha, monga mwayi wocheperako wa lens ya telephoto ndi kamera yotalikirapo kwambiri, koma chofunikira kwambiri, chithunzi chomwe chikubweracho sichingawoneke bwino momwe mungayembekezere. Ngati mwaganiza zobwerera ku zoikamo zoyambirira mukamawombera wamba, dinani chizindikiro cha chiŵerengero kachiwiri ndikusankha njira ya 3:4.

Pansipa tikuwona kusintha kwamtundu wazithunzi pachithunzi chachiwiri chomwe chidatengedwa ndi pixel binning. Palibe kusiyana kwakukulu pankhani ya phokoso, koma ngati muyang'anitsitsa, mizere imatanthauzidwa kwambiri mu chithunzi chachiwiri. Mphepete mwachifaniziro choyamba zimawoneka zokhotakhota mutabzala, makamaka kumunsi kumanja. Mu seti ina yotengedwa mkati mwamdima kwambiri, chithunzi choyamba popanda binning ndi chakuda ndipo timapeza phokoso lochulukirapo kuposa chithunzi chachiwiri chokhala ndi binning. Inde, palibe chithunzi chomwe chikuwoneka bwino, koma panalibe kusowa kwenikweni kwa kuwala.

N'chimodzimodzinso ndi zithunzi zina, pamene choyamba ndi chosiyana kwambiri ndi chachiwiri. Yoyamba, yotengedwa motsimikiza, ikuwonetsa phokoso lochulukirapo kuposa lomwe lidatengedwa masekondi angapo pambuyo pake ndi makamera okhazikika a S22 Ultra. Zodabwitsa ndizakuti, pazithunzi ziwiri zomaliza za 108 megapixels, zina mwazambiri zidatayika, pomwe mawu akuti "Nashville, Tennessee" pakona yakumanja kwa chithunzicho sichingawerengedwe.

Pafupifupi m'zitsanzo zonse zomwe zili pamwambazi, zochitikazo zinali zakuda kwambiri kotero kuti anthu ambiri sakanaganiza ngakhale kujambula. Koma ndizosangalatsa kwambiri kuziyerekeza. Pixel binning ndi ya masensa ang'onoang'ono a makamera apamwamba omwe amabwera ndi mafoni ambiri. Android, ndizofunikira chifukwa zimawathandiza kuzindikira makamaka zochitika zamdima. Ndi kunyengerera, chigamulocho chidzachepetsedwa kwambiri, koma mphamvu ya kuwala idzawonjezeka. Kuchuluka kwa ma megapixels kumagwiranso ntchito, mwachitsanzo, kukulitsa mapulogalamu pojambula kanema mu 8K, zomwe zimapangitsa kuti zikhale zosavuta, ngakhale kujambula mu chisankho ichi sikunali kofala.
Ndipo izi zikutanthauza chiyani? Kugwiritsa ntchito ma pixel binning kuti muwonjezere kumva kwa kuwala kumakhala komveka, ngakhale zotulutsa zocheperako sizosiyana kwenikweni, makamaka pa S22 Ultra.
