Adam Kos Munali 2016 ndipo Apple adayambitsa iPhone 6S. Monga chimodzi mwazinthu zatsopano zatsopano, adabweretsa kuwonjezeka kwa ma megapixels a kamera yake, mpaka 12 MPx. Ndipo monga zimadziwika, chisankhochi chimasungidwanso ndi mndandanda wamakono, mwachitsanzo, iPhone 13 ndi 13 Pro. Koma bwanji izi zili choncho pomwe mpikisano umapereka ma MPx opitilira 100?
Osazindikira angaganize kuti Samsung Galaxy S21 Ultra yokhala ndi 108 MPx iyenera kumenya ma iPhones. Komabe, zikafika pamtundu wa kamera, zambiri sizili bwino. Chabwino, makamaka pankhani ya MPx. Mwachidule, ma megapixels sizofunikira pano, koma mtundu (ndi kukula) kwa sensa. Chiwerengero cha MPx kwenikweni ndi chinyengo chabe cha malonda.
Ndi za kukula kwa sensa, osati kuchuluka kwa MPx
Koma kunena chilungamo, inde, ndithudi chiwerengero chawo chimakhudza zotsatira zake pamlingo wina, koma kukula ndi khalidwe la sensa ndilofunika kwambiri. Kuphatikiza kwa sensor yayikulu yokhala ndi nambala yochepera ya MPX ndikoyenera kwenikweni. Apple imatsatira njira yomwe imasunga ma pixel, koma nthawi zonse imachulukitsa kachipangizo, motero kukula kwa pixel imodzi.

Ndiye chabwino nchiyani? Khalani ndi 108 MPx pomwe pixel iliyonse ili ndi kukula kwa 0,8µm (nkhani ya Samsung) kapena mukhale ndi 12 MPx pomwe pixel iliyonse ndi 1,9µm kukula kwake (nkhani ya Apple)? Kukula kwa pixel, kumanyamula zambiri komanso kumapereka zotsatira zabwinoko. Mukawombera pa Samsung Galaxy S21 Ultra yokhala ndi kamera yake yoyamba ya 108MP, simudzakhala ndi chithunzi cha 108MP. Kuphatikiza kwa ma pixel kumagwira ntchito pano, zomwe zimapangitsa kuti mwachitsanzo ma pixel aphatikizidwa kukhala amodzi, kotero kuti ikhale yayikulu pomaliza. Ntchitoyi imatchedwa Pixel Binning, ndipo imaperekedwanso ndi Google Pixel 4. Nchifukwa chiyani izi zili choncho? Inde ndi za khalidwe. Pankhani ya Samsung, mutha kuyatsa kujambula zithunzi pazosintha zonse za 6MPx, koma simukufuna.
Izo zikhoza kukhala chidwi inu
Kuyerekeza kodziyimira pawokha
Ubwino wokhawo wa kuchuluka kwa ma megapixels ukhoza kukhala pazithunzi za digito. Samsung imapereka makamera ake kuti mutha kujambula nawo mwezi zithunzi. Inde, zimatero, koma zoom ya digito imatanthauza chiyani? Zangodulidwa kuchokera pa chithunzi choyambirira. Ngati tikukamba za kufananitsa kwachindunji kwa Samsung Galaxy S21 Ultra ndi iPhone 13 Pro mafoni, tangowonani momwe mafoni onsewa adakhalira pagulu lodziwika bwino lazithunzi. Chithunzi cha DXOMark.

Apa, iPhone 13 Pro ili ndi mfundo 137 ndipo ili pa 4th. Samsung Galaxy S21 Ultra ndiye ili ndi mfundo 123 ndipo ili pamalo a 24. Zachidziwikire, pali zofunikira zambiri zomwe zikuphatikizidwa pakuwunika, monga kujambula kanema, ndipo ndizokhudzanso kukonza pulogalamuyo. Komabe, zotsatira zake zikunena. Chifukwa chake kuchuluka kwa MPx sikungokhala kotsimikiza pakujambula kwamafoni.
Ndizofunikira kudziwa kuti Samsung yosiyana kotheratu ndi pulogalamu yosamalizidwa idavoteledwa pamndandanda womwewo, ndipo lero mawonekedwe a kamera ndi apamwamba kwambiri.
Ndipo ndikofunikira kuwonjezera kuti Apple ndiyosiyana kwambiri ndi Android yotseguka;)
Erm IOS :)
