Kushandiswa kwekamera imwe chete kuwana mafoto akasviba hachisi chinhu chitsva, chekareiPhone XRuye kareGoogle Pixel 2vakaedza zvakafanana.
Apple itsva iPhone SE yakafanana, asi yayokameraelement yanyanya kuchembera, iyo main credit ichiri mu algorithm.
Kubva mushumo we disassembly we iFixit, tinogona kuona kuti zvimwe zvikamu mu iPhone SE itsva zvinonyatsoenderana neiPhone 8, kunyangwe kusvika pakugona kushandiswa kwakasiyana-kusanganisira 12-megapixel wide-anglekamera .
Tsika ye 'waini nyowani mumabhodhoro ekare' haina kujairika kune iyo iPhone SE.Kudzokera kumakore mana apfuura, chizvarwa chekutanga iPhone SE chakashandisawo chitarisiko che5s uye yakawanda yehardware, saka Apple inogona kupa mutengo wakaderera.
Zvichienderana, kana uchikopa imwechete kamera hardware, iyokameramaitiro ezviviri izvi hazvifanirwe kunge zvakasiyana zvakanyanya.Semuyenzaniso,iPhone 8haitsigire kutora hudiki hudiki hwemifananidzo yemunda ine chinyorwa chakajeka uye isina kujeka kumashure, izvo zvatinowanzodaidza kuti "portrait mode".
Asi paunotarisa peji rekutsigira reApple, uchaona kuti iyo portrait mode isingatsigirwe neiPhone 8inotsigirwa neiyo itsva iPhone SE-kunyangwe kana iyo yekumashure lens yakatarwa yeaya maviri akafanana.
Mumamiriro ezvinhu akajairwa, kutora mafoto akasviba parunhare mbozha kazhinji kunoda kuitwa nemakamera maviri-semeso emunhu, nharembozha inodawo kuwana mifananidzo miviri pamakona akasiyana kuburikidza nemalenzi maviri munzvimbo dzakasiyana, uye wozobatanidza makona. tarisa Musiyano unofungidzira hudzamu hwemunda kuti uwane kusajeka kwemashure uye chengetedza chinyorwa chakajeka.
Iyo Plus nhevedzano pane iyo rondedzero, kana iyo X, XS, uye 11 mumakore achangopfuura, vanovimba zvakanyanya neakawanda-kamera masisitimu kuti apedze mufananidzo wakasviba kupfura.
Saka iyo iPhone yekumberi imwe kamera inogadzirisa sei?Iyo yakakosha iri mune infrared dot matrix purojekita muFace ID system, iyo inogona zvakare kuwana yakakwana yakakwana data yehudzamu, iyo yakaenzana ne 'yebetsero lenzi'.
Kubva pane iyi maonero, iyo iPhone SE inogona kutora mapikicha emhando yemifananidzo yakakosha: kutanga, haitore mapfuti akawanda, chechipiri, haina Face ID, hapana mukana wekutsigirwa kwehardware.
Sezviri pachena, Apple yakaita shanduko dzatisingaone padanho resoftware.
Munguva pfupi yadarika, Ben Sandofsky, mugadziri wechitatu-bato kamera application Halide, akaburitsa misimboti yehunyanzvi, achitsanangura kuti sei iyo itsva iPhone SE ichishandisa zvakafanana-lens zvirevo senge.iPhone 8, asi inogona kuwana iyo portrait foto modhi iyo yekupedzisira haigone.
Vakataura kuti itsva iPhone SE ingangove 'yekutanga iPhone inogona kuburitsa mufananidzo wakasviba uchishandisa chete mufananidzo we2D'.
Unogona kutaura kutiiPhone XRzvakare haisi yekudzima-kamera imwe chete.Ko SE haisi kungoikopa here?
Zvisinei, kuparara kwemamiriro ezvinhu kwakaratidza kutimakameraye iPhone SE uyeiPhone XRhazvina kuenderana, izvo zvinotungamirawo kune mutsauko mukuitwa kwehunyanzvi hwezviviri.
▲Samsung Galaxy S7series ndiyo yekutanga mudziyo unoshandisa tekinoroji yeDPAF pane smartphonekamera
Chinhu chinonyanya kukosha ndechekutikamerayeiPhone XRinogona kushandisa dual pixel autofocus (DPAF) tekinoroji, iyo inoibvumira kuwana imwe data yakadzika yakavakirwa pane Hardware.
Nemashoko akareruka, tekinoroji yeDPAF yakaenzana nekugovanisa pixel panekamerasensor mumapikisi maviri madiki padivi-padivi kutora mafoto maviri nemakona akasiyana, semeso edu ekuruboshwe nekurudyi.
Kunyangwe musiyano wemakona unogadzirwa neizvi hausi pachena seuyo wembirikamera, ichiri kubatsira kune algorithm kugadzira data yakadzika.

Kare,Googlezvakare yakashandisa tekinoroji iyi paPixel 2, 3kuwana single-shot blur.PaPixel4, nekuti kamera inotsiviwa neyakawanda-kamera yakatarwa, kuona parallax kwakanyatso kurongeka kupfuura imwe-kamera.
▲ Ngatitarisei data rakatorwa nePixel 4 vachishandisa makamera maviri.
Kana iri iyo itsva iPhone SE, nekuti masensa ayo anyanya kuchembera, Halide anoti haigone kuvimba nema sensors kuti iwane mamepu akasiyana, uye zvakanyanya kungovimba nemuchina wekudzidza algorithm wakapihwa neA13 Bionic chip kutevedzera uye kugadzira data rakadzama. maps.
Imwe tsananguro yemutsara ndeyekuti iyo iPhone SE portrait blur kupfura inowanikwa zvachose nesoftware uye algorithms.
▲ Tora mufananidzo uyu zvakananga nawoiPhone XRuye itsva iPhone SE
Halide akashandisa iyoiPhone XRuye iyo itsva iPhone SE kutora mufananidzo wembwa (kwete pfuti chaiyo, kungotora mufananidzo we 'mufananidzo mumwe'), wobva waenzanisa data rakadzama remifananidzo miviri.
Vakaona kutiiPhone XRwakangoita chikamu chakareruka chemufananidzo kuti uburitse muviri mukuru, asi hauna kunyatso kuziva nzeve yembwa.
