Masiku ano, sizachilendonso kukumana ndi mafoni a m'manja okhala ndi 100 MPx. Makamaka, mafoni osiyanasiyana a Samsung okhala ndi Ultra moniker akhala ndi kamera ya 108MPx kwakanthawi tsopano. Kuphatikiza apo, makamera okhala ndi malingaliro apamwamba kwambiri amafika anthu apakati. Mwachitsanzo Samsung yokha idayiyikamo Galaxy A73. Komabe, mafoni awa amatengabe zithunzi za 12MP mwachisawawa. Koma n’chifukwa chiyani zili choncho?
Kodi ma megapixels onsewa ndi chiyani pomwe makamera amajambulabe zithunzi zazikuluzikulu? Sizovuta kudziwa. Makamera a digito amakhala ndi masauzande ndi masauzande a masensa ang'onoang'ono, kapena ma pixel. Kusintha kwapamwamba kumatanthawuza ma pixel ochulukirapo pa sensa, ndipo ma pixel ochulukirapo omwe amakwanira pamtunda womwewo wa sensa, ma pixel awa ayenera kukhala ochepa. Chifukwa ma pixel ang'onoang'ono amakhala ndi malo ang'onoang'ono, sangathe kusonkhanitsa kuwala kochuluka ngati ma pixel akuluakulu, zomwe zikutanthauza kuti amachita moipitsitsa powala kwambiri.
Mutha kukhala ndi chidwi ndi
kujambula kwa pixel
Koma makamera amafoni a megapixel apamwamba nthawi zambiri amagwiritsa ntchito njira yotchedwa pixel binning kuti athane ndi vutoli. Ndi nkhani yaukadaulo, koma mfundo ndi yakuti ngati zichitika Galaxy S22 Ultra (ndipo mwina A73 yomwe ikubwera) imaphatikiza magulu a ma pixel asanu ndi anayi. Kuchokera pa 108 MPx, masamu osavuta amapeza 12 MPx (108 ÷ 9 = 12). Izi ndizosiyana ndi Pixel 6 ya Google, yomwe ili ndi masensa a kamera a 50MP omwe nthawi zonse amatenga zithunzi za 12,5MP chifukwa amaphatikiza ma pixel anayi okha. Galaxy Komabe, S22 Ultra imakupatsaninso mwayi wojambulira zithunzi zokhazikika molunjika kuchokera ku pulogalamu yamakamera.
Zitsanzo zithunzi Galaxy Zithunzi za S22Ultra
Pixel binning ndiyofunikira pamasensa ang'onoang'ono amakamera owoneka bwino, chifukwa izi zimawathandiza pazithunzi zakuda. Ndiko kunyengerera komwe kusamvana kudzachepa, koma kukhudzidwa kwa kuwala kumawonjezeka. Kuwerengera kwakukulu kwa megapixel kumalolanso kusinthasintha kwa mapulogalamu / digito zoom ndi kujambula kanema wa 8K. Koma ndithudi ndi mbali chabe malonda. Kamera ya 108MP imawoneka yochititsa chidwi kwambiri malinga ndi mawonekedwe kuposa kamera ya 12MP, ngakhale imakhala yofanana nthawi zambiri.
Mutha kukhala ndi chidwi ndi
Komanso, zikuwoneka kuti agonjeranso izi Apple. Pakalipano, wakhala akutsatira ndondomeko yolimba ya 12 MPx ndi kukulitsa kosalekeza kwa sensa ndipo motero ma pixels payekha. Komabe, iPhone 14 iyenera kubwera ndi kamera ya 48 MPx, yomwe ingophatikiza ma pixel 4 kukhala amodzi motero zithunzi 12 za MPx zidzapangidwanso. Pokhapokha ngati ndinu wojambula wodziwa zambiri ndipo simukufuna kusindikiza zithunzi zanu mumitundu yayikulu, ndikofunikira kusiya kuphatikiza ndi kuwombera 12 MPx.
Si malonda, mu kuwala kwabwino zithunzi zonse ndi zatsatanetsatane ndipo izi zimagwiritsidwanso ntchito pojambula (digito), optically imayambira pa 3x.
Kuwala bwino, kumawonjezera kuchuluka popinda.
Inde, makulitsidwe a digito ndi mpaka 100x. Komabe, kugwiritsa ntchito kwake kuli ndi zotsutsana.
100x ndiyonyanyira ndithu, koma chirichonse pakati pa 1x ndi 3x chiri bwino kwambiri pakuwala bwino chifukwa cha sensa yayikuluyi yokhala ndi mpix wambiri. Moyipa, mwayi wapita ...
