Ofufuza a MIT awulula kusintha kwa chipset kuti kujambula mafoni

Ofufuza ku Massachusetts Institute of Technology apanga chipset chatsopano cha masensa azithunzi, omwe apanganso kujambula kwama smartphone.

Maola angapo apitawo, Aptina wavumbula masensa awiri atsopano azithunzi azida zamagetsi. Masensawa akuwonetsa kuti mtundu womwe umatchedwa megapixel ulipobe, ngakhale HTC idavumbulutsa ukadaulo wake wa "Ultrapixel" mu One smartphone ndikuti ma megapixels ambiri amakhala ndi "katundu wambiri".

Zomvera zatsopano za Aptina 12 ndi 13-megapixel zitha kupezeka m'mafoni ndi mapiritsi kumapeto kwa chaka cha 2013. Kampaniyo imalonjeza kujambula kwa 4k kopitilira muyeso HD kanema ndikuchita "modabwitsa" m'malo opepuka.

Chipset chatsopano cha MIT chithandizanso kujambula zithunzi zam'manja m'malo ochepa

Komabe, chip chatsopano chopangidwa ndi ofufuza a MIT akuti chimasintha zithunzi za smartphone. Njirayi idakhazikitsidwa ndi njira yatsopano yomwe ingasinthe zithunzi zowoneka ngati zithunzi zowoneka akatswiri.

Izi sizidzafuna kuchitapo kanthu kuchokera kwa ogwiritsa ntchito, omwe angodina batani kuti musinthe zithunzi zawo. Pulosesa ya chithunzi chojambulira imatha kuthana nayo Kujambula kwa HDR mosavuta komanso mwachangu, kwinaku mukudya mphamvu zochepa.

Kutenga zithunzi zambiri kumadya batri yambiri, koma chipset chatsopano chimasunga mphamvu, pochita ntchito zingapo, Wolemba wamkulu Rahul Rithe. The kukonza kwa HDR mwachangu idzakhala yothandiza kwambiri pakujambula mafoni otsika, anawonjezera Rithe.

Chip chatsopano cha MIT cha masensa azithunzi, omwe amatha kujambula zithunzi zowoneka ngati akatswiri pama foni am'manja, zawululidwa.

Chojambulira chithunzi chimatenga zithunzi ziwiri nthawi imodzi: imodzi yokhala ndi kung'anima, imodzi yopanda

Zithunzi zamagetsi zomwe zikubwera potengera ukadaulo uwu zitha kuthana ndi vuto lalikulu lazithunzi zochepa: zithunzi zopanda kuwala ndi zakuda kwambiri kuti zisakhale zothandiza, pomwe zithunzi zokhala ndi flash zimawonekera kwambiri ndikukhudzidwa ndi kuyatsa kovuta.

Chojambulira cha MIT chimajambula zithunzi ziwiri, chimodzi chopanda kung'anima ndi chimodzi chowala. Tekinolojeyi imagawaniza zithunzizo m'magawo awo, kenako zimaphatikiza “Zachilengedwe” kuchokera pa chithunzi chopanda kung'anima ndi "Zambiri" kuchokera kwa yemwe ali ndi kuwala, ndi zotsatira zosangalatsa.

Njira yatsopano yochepetsera phokoso

Makinawa amathanso kuchepetsa phokoso, chifukwa chapadera "Fyuluta yamayiko awiri". Malinga ndi Rithe, fyuluta iyi imangosokoneza ma pixels oyandikana nawo owala ofanana.

Ngati mawonekedwe owala ali osiyana, ndiye kuti makinawo sangasokoneze ma pixels chifukwa adzawona kuti ndi gawo la chimango. Zinthu zomwe zili mu chimango zikuyembekezeka kukhala ndi mawonekedwe owala mosiyanasiyana, pomwe zinthu zakumbuyo zimakhala ndi kuwala kofanana.

Chipset chatsopano cha MIT chizigwira njira zingapo nthawi imodzi. Komabe, imatha kugwira ntchitoyi mosavuta, chifukwa cha njira yosungira deta yotchedwa “Gridi yamayiko awiri”.

Tekinoloje imeneyi imagawaniza chithunzicho m'magawo ang'onoang'ono ndikupatsa histogram pagawo lililonse. Fyuluta yamayiko awiri idziwa nthawi yoti tileke "kusokonekera m'mbali" chifukwa ma pixels agawanikana pagululi.

Zitsanzo zogwirira ntchito zilipo, koma osakonzekera nthawi yayikulu

Ofufuzawa apanga kale mtundu wogwira ntchito, wololedwa ndi Taiwan Semiconductor Manufacturing Company, kampani yayikulu kwambiri padziko lonse lapansi yopanga semiconductor. Ntchitoyi idathandizidwa ndi Foxconn, imodzi mwamagetsi opanga magetsi padziko lonse lapansi, omwe amapanga zida za Sony, Apple, ndi ena ambiri.

Chithunzi chojambulira chimachokera ku teknoloji ya CMOS 40-nanometer ndipo pakali pano ikuyesedwa kwambiri. Ofufuza ku MIT sanalengeze kuti zithunzithunzi zopangidwa ndi chipsetzi zizipezeka pati pamsika.
