Tan iyo 2018, kamaradaha casriga ah ayaa bilaabay "dagaal dijital ah" cusub oo megapixels ah. Kaamirooyinka ayaa noqday kuwa ugu badan ee lagu iibiyo talefannada casriga ah, waxaana xoogga la saaray tirada megapixels-ka ee xirmada casriga ah ee kamaraddeeda. Dadka intiisa badan waxay aaminsan yihiin in megapixels badan ay ka dhigan tahay tayada sawirka wanaagsan. Tani waxay keenaysaa su'aasha - Ma waxaan u baahanahay kamaradaha casriga ah ee megapixel sare si aad u gujiso sawiro ka fiican iyo duubista fiidiyowyada?
megapixels-yada kamaradu waxay go'aamiyaan tayada kamaradda laakiin maaha qodobka kaliya iyo runtu waxay tahay in megapixels badan aysan macnaheedu ahayn tayada muuqaalka wanaagsan. Dhab ahaantii, qaar ka mid ah soosaarayaasha casriga ah ee ugu wanaagsan warshadaha ayaa wali isticmaala kamarad 12 MP ah, gaar ahaan Apple oo leh tirooyinka megapixel ugu hooseeya ee kamarad kasta oo casriga ah.
Fikradda kamaradaha iyo megapixels waa ka yara dhib badan sida ay u muuqato, aan si qoto dheer u dhex galno si aan u fahanno waa maxay muhiimadda megapixels oo ma u baahanahay kamaradaha casriga ah ee megapixels?
Waa maxay megapixel iyo sidee buu u saameeyaa tayada kamarada?
Marka hore aan fahano waxa uu yahay megapixel. Asal ahaan, Megapixel waxaa loola jeedaa hal milyan oo pixels waxaana badanaa loo isticmaalaa in lagu muujiyo xallinta kamaradaha dhijitaalka ah. pixel-ku waa afar geesle yar oo ku yaala kormeeraha kumbuyuutarka, waa yar yahay wuxuuna ku yimaadaa qaab dhibco. Sawirku waa shabag adag oo labajibbaaran ama dhibco ah.
Marka ay bataan pixels ama dhibco ka kooban bandhigga, ayaa sii fiiqan xallinta ama sawirka. Marka ay sare u kacdo tirada dhibcaha ama pixels, ayaa si aad ah loo sifeeyay sawirku, taas oo u oggolaanaysa in kor loo qaado sawirka dhabta ah. Shaqada tayada sawirka waxaa lagu cabbiraa megapixels. Tusaale ahaan, kamarad 3.1-megapixel ah waxay qaadi kartaa sawiro iyadoo xalkeedu yahay 2048 x 1536 (oo u dhiganta 3,145,728 pixels). Taasi waa, sawirka ugu dambeeya wuxuu ka koobnaan doonaa 3.1 megapixels ama in ka badan 3 milyan oo dhibcood.
Dareemayaasha kamaradaha dhijitaalka ah ayaa ku kala duwan cabbirkooda. Dareemaha gudaha taleefanka casriga ah wuu ka yar yahay dareeraha ku jira kamarada dareeraha dalagga, kaas oo haddana ka yar shideeyaha gudaha qaab buuxa oo DSLR ah. Si kastaba ha ahaatee, dhammaan saddexda kamaradood waxay yeelan karaan dareemayaal 12MP ah. Waxa isbeddelaya waa cabbirka barta iftiinka ee dareenka. Kaamirada casriga ah, way yar yihiin, iyo kamarad qaabaysan, way ka weyn yihiin. Tani waxay saamaysaa tayada sawirka guud.
Inkasta oo ay muhiim tahay in la ogaado in megapixels aysan ahayn qodobka kaliya ee saameeya tayada sawirka. Xaqiiqdu waxay tahay in megapixels badan aysan macnaheedu ahayn tayo badan. Tayada kamaradda waxaa si isku mid ah loo go'aamiyaa tayada dareemayaasha, sidoo kale, tayada muraayadaha ayaa sidoo kale ka ciyaara door muhiim ah. Asal ahaan, haddii aad isticmaasho kamarada casriga ah ee leh dareemayaasha liita iyo muraayadaha liidata ee leh Megapixels badan, waxaad yeelan doontaa pixels tayo liita.
Ma u baahanahay kamaradaha casriga ah ee megapixel sare?
Kamarad 12-megapixel ah oo ku taal dhabarka Google Pixel ama Apple iPhone waxay qaadi doontaa sawiro cajiib ah, kaliya waa inaad fiirisaa sawirada ay qabteen OnePlus 10 Pro, Samsung S22, iyo Xiaomi 12 pro Si loo arko natiijooyinka cajiibka ah ee kamaradahani ay sidoo kale dhalin karaan.
Maya, kamarad megapixel sare muhiim maaha, Megapixels waxay leeyihiin door muhiim ah laakiin xaqiiqdii maaha sababta ugu weyn ee tayada kamaradu u wanaagsan tahay ama u xun tahay. Waxaa jira arrimo badan oo kaamirada ka dhigaya mid weyn, tirinta megapixels-kana waa mid ka mid ah, haddaba ka hor inta aadan fiirin tirada megapixels ee kamarada casriga ah, kaliya hubi inaad sidoo kale hubisay arrimo kale. Ha ku indho beelin nambarada megapixels oo xusuusnow in software-ku uu sidoo kale yahay qayb muhiim ah oo ka mid ah isla'egta sawirka.
Qaar ka mid ah sawirada waaweyn ee warshadaha kamaradaha ayaa aaminsan in talefanka sare ee pixel uu yahay khasaare. Michael Kaschke, oo ah maamulaha caanka ah ee caanka ah ee German lens lens Carl Zeiss (hadda loo yaqaan Zeiss) ayaa qiray waagii hore. Dadka aqoonta u leh goobta casriga ah ayaa laga yaabaa inay ogaadaan in Zeiss uu hadda siinayo qaybaha muraayadaha/teknooloojiyada sawir-qaadista ee Nokia (HMD), Sony, iyo Vivo. Sidaa darteed, si adag u hadla, mudane Tani dhab ahaantii waa xiiso gaar ah ee sawirka casriga ah ee casriga ah maanta - markaa muxuu u dhaleeceeyay taleefannada gacanta ee aadka u sarreeya?
Wuxuu si cad uga soo horjeedaa dhaqanka "piles of pixels ee maskaxda la'aanta". Fikraddiisa, in aan la xusin dareenka yar ee casriga ah, xitaa haddii ay tahay dusha sare ee calanka SLR-ga buuxa, maaddaama cabbirka dareenka laftiisa uu go'an yahay, kordhinta tirada pixels waxay la macno tahay in la yareeyo aagga sawir-qaadista. Mid kasta oo pixel ah, iyo tani waxay si lama filaan ah u horseedi doontaa hoos u dhaca dareenka iftiinka, taasoo keenta buuq badan oo sawirka.
Natiijo ahaan, isticmaaleyaasha talefanka gacanta ee caadiga ah (kameerada), waxay dareemi doonaan in pixels badan aysan dhab ahaantii keenin tayada sawir wanaagsan; iyo isticmaalayaasha leh baahiyaha xirfadeed, tani waxay ka dhigan tahay maalgashi dheeri ah oo qalab ah. qashin.
Qaarkiin ayaa laga yaabaa inay rabaan inay ka hortagaan iyagoo leh "miyaydaan arkayn in astaanta XX aan lagu habeynin CMOS xasaasi sare leh? Miyaanay taasi ahayn talefanka gacanta ee summada XXXX ee sheeganaya inuu awood u leeyahay inuu isticmaalo farsamaynta AI si uu tayada sawirka u caddeeyo? Taas oo laga jawaabayo, Kaschke tilmaamay Xataa xitaa kuwa ugu dambeeyay ee mobilada gacanta lagu hayo ee ugu weyn (SoC), xusuusta taleefanka gacanta ee ugu dhaqsaha badan iyo xusuusta flash-ka runtii ma laha awood ay ku farsameeyaan sawirada 40 milyan ama ka sareeya heerka pixels.
Sababtan awgeed, taleefannada casriga ah ee leh nashqada aadka u sarreeya ee pixel, iyada oo aan laga reebin, ma daari doonaan qaabka pixel ultra-sare si caadi ah laakiin waxay sawiri doonaan habka loo yaqaan "afar-in-one". Sidan oo kale, ma aha oo kaliya in ay yarayso suurtogalnimada buuqa iyada oo loo marayo isku-dhafka pixel laakiin sidoo kale waxay yaraynaysaa cadaadiska xisaabinta ee processor-ka, taas oo u oggolaanaysa in ay qabato hoos u dhigista qaylada waqtiga-dhabta ah, HDR, qurxinta, iwm. Xitaa taleefannada gacanta ee calanka leh, "waxqabadka" sawir qaadista kuma filna
Ma dareemaysaa niyad jab yar markaad aragto tan? Run ahaantii, waxaan sidoo kale la yaabay markii ugu horreysay ee aan ogaaday xaqiiqda ah in telefoonnada gacanta ee hadda jira aysan awood u lahayn inay sawirro ku qaadaan 40 megapixels.
erayada Final
Markaa ma waxaan u baahanahay kamaradaha casriga ah ee megapixel sare? Hagaag, jawaabtu waa Maya, sida loo kariyo kamarada casriga ah ee kaamil ah waxay ku jirtaa software-keeda, awooda farsamaynta, iyo arrimo kale oo badan. megapixels-yada sare waxay ogolaadaan goynta ku habboon iyada oo aan la dhimin xallinta, qabashada sawirro aad u faahfaahsan, oo ay kordhiyaan tayada sawirka iyo fiiqan laakiin waa haddii guud ahaan isla'egta sawirku ay dheelli tiran tahay.
