Bell Labs imapanga kamera yopanda mandala kutengera pixel imodzi

Bell Labs ikhoza kusintha msika wojambula zithunzi pogwiritsa ntchito kamera yopanda magalasi yotengera zomwe zimatchedwa "compressive sensing" yomwe imagwiritsa ntchito pixel imodzi.

Bell Labs ikuyang'ana kuwonetsa kuti makampani opanga zithunzi sakuyenda. Ofufuza pamalo opangira chitukuko ndi omwe ali ndi udindo wopanga zinthu zambiri, monga laser, UNIX, C++, transistor, ndi chipangizo chodziwika bwino chophatikizana chopezeka mumakamera ambiri.

Ofufuza a Bell Labs apanga kamera yomwe imagwiritsa ntchito sensa imodzi ya pixel ndi kabowo kakang'ono kujambula zithunzi. Sichifuna mandala, m'malo mwake kudalira luso lamakono lamakono, kutanthauza kuti dongosolo lonse likhoza kusintha msika wa makamera a digito.

Kamera yopanda magalasi yotengera luso la "compressive sensing" lopangidwa ndi ofufuza a Bell Labs

Asayansi ku Bell Labs apambananso mphotho za Nobel pazomwe adapeza ndipo zikuwoneka ngati atsala pang'ono kusinthanso dziko lapansi. Zomwe zapangidwa posachedwa zimakhala ndi mtundu watsopano wa kamera, yomwe imadalira pixel imodzi kuti ijambule zithunzi, m'malo mwa lens.

Ukadaulo watsopano udakhazikitsidwa pamalingaliro ophatikizika, omwe, kwenikweni, amafotokoza tanthauzo la redundancy. Ofufuza akukhulupirira kuti zambiri zitha kupezeka kuchokera kuzinthu zomwe tikugwiritsa ntchito masiku ano ndikuti kwenikweni anthu akuyenera kuwongolera miyeso yake.

Asayansi ku Bell Labs apeza njira yowonera miyeso moyenera ndikuphatikizanso deta m'njira yoyenera. Njirayi yasonyezedwa kale ndi asayansi ku Shanghai Institute of Optics ndi Fine Mechanics, China, omwe atha kupanga chithunzi cha 3D pogwiritsa ntchito pixel imodzi.

Kamera yopanda mandala ya Bell imakhala ndi sensor imodzi ya pixel ndi kabowo kakang'ono mu gulu la LCD.

Ukadaulo wapititsidwa patsogolo ndi Bell Labs yochokera ku New Jersey. Gang Huang ndi anzake apanga kamera yomwe imagwiritsa ntchito makina okakamiza kupanga zithunzi. Sichifuna mandala, monga makamera m'zaka 150 zapitazi, m'malo mwake kudalira pixel imodzi.

Asayansi amanena kuti makinawo amachokera pamagulu a ma apertures, omwe ali ndi gulu la LCD, ndi sensa ya zithunzi. Kuphatikiza apo, chipangizochi sichidzapanganso zithunzi zakunja.

Pali zotsegula zingapo mu gulu la LCD. Iliyonse imalola kuwala kudutsamo ndipo iliyonse imatsekedwa panthawi ina. Komabe, mndandandawu sunakonzedweratu, chifukwa ndondomeko yonseyi iyenera kukhala yosasinthika kuti zitsimikizire kuti mitundu yonse itatu ya kuwala ikufika pa sensa imodzi ya pixel.

Mukufuna zithunzi zapamwamba kwambiri? Gwiritsani ntchito kabowo kakang'ono kuti mujambule zithunzi zambiri

Kupanga chithunzicho ndikosavuta kwambiri, popeza sensor imagwira kuwala ngati sensa wamba. Monga tafotokozera pamwambapa, mawonekedwe a zobowola amakhala mwachisawawa, kutanthauza kuti chipangizocho chiyenera kujambula chithunzi chomwecho kangapo.

Pambuyo pake, umisiri wa compressive sensing ukusanthula deta ndikubwezeretsanso chithunzicho. Ofufuzawo adachotsanso njirayo potulutsa chithunzi choyesera, chomwe chatengedwa pogwiritsa ntchito deta yochepa.

Bell Labs imanena kuti mafelemu akamajambulitsa mazenera ambiri, ndiye kuti chithunzicho chimakhala chapamwamba kwambiri.

Ubwino kuposa makamera wamba

Asayansi anatsindika zimenezi pazabwino za kamera yawo yopanda magalasi komanso zomwe zingachitike mdziko la kujambula kwa digito. Amati zithunzizo zimagwiritsa ntchito deta yocheperako, chifukwa chake ojambula sangafunenso zida zazikulu zosungirako.

Komanso, kusowa kwa mandala kumatanthauza kuti kusintha kwa chromatic ndi chinthu chakale. Ogwiritsa ntchito sadzayenera kubwezeranso kukonzanso kwa magalasi, pomwe zithunzi sizidzangoyang'ana.

Malinga ndi Bell Labs, nkhondo za megapixel zidzathanso. Ngati ojambula akufuna chithunzi chapamwamba kwambiri, ndiye kuti amangofunika kujambula mafelemu ambiri pogwiritsa ntchito kabowo.

Ukadaulo wopondereza ungapangitsenso zithunzi za 3D kukhala zosavuta kujambula. Opanga makamera adzayenerabe kugwiritsa ntchito masensa azithunzi awiri, koma azitha kugwiritsa ntchito ma apertures ofanana.

Pomaliza, makamera opanda magalasi adzakhala otsika mtengo kwambiri kupanga. Chitsanzo choyambirira chapangidwa ndi zigawo za "off-the-shelf", zomwe ndi zotsika mtengo.

Palinso zovuta zina

Ofufuzawo avomereza kuti pali zovuta zina, komanso. Iwo amati zimatenga nthawi yambiri kuti asonkhanitse deta ya chithunzicho, makamaka ngati mukufuna kupeza zithunzi zapamwamba.

Kuphatikiza apo, kamera siyitha kujambula mavidiyo. Popeza kuti chimango chimodzi chimafuna nthawi yochuluka kuti chisonkhanitsidwenso, n’zosatheka kujambula zithunzi zoyenda panopa.

Komabe, chinthu chabwino ndichakuti ukadaulo usintha posachedwa ndipo zikuyenera kutsimikiziridwa kuti ndi zinthu ziti zabwino zomwe munthu angachite ndi kumvera kokakamiza.
