Samsung idakhazikitsa sensor yatsopano ya 200MPx masabata angapo apitawo ISOCELL HP3. Iyi ndiye sensa yokhala ndi pixel yaying'ono kwambiri kuposa kale lonse. Tsopano, chimphona chaukadaulo waku Korea chalankhula za chitukuko chake kudzera mwa opanga magawo a System LSI ndi Semiconductor R&D Center.
Sensa ya zithunzi (kapena photosensor) ndi semiconductor yamagetsi yomwe imasintha kuwala komwe kumalowa mu chipangizocho kudzera mu lens ya kamera kukhala zizindikiro za digito. Masensa azithunzi amapangidwa muzinthu zonse zamagetsi zomwe zimakhala ndi kamera, monga makamera adijito, ma laputopu, magalimoto komanso, ma foni a m'manja. ISOCELL HP3, yoyambitsidwa ndi Samsung mu June, ndi photosensor yomwe ili ndi ma 200 miliyoni 0,56 micron pixels (kukula kwa pixel yaying'ono kwambiri) mu mawonekedwe a 1/1,4 ″.
"Ndi ma pixel ang'onoang'ono ang'onoang'ono, kukula kwa thupi la sensa ndi module kumatha kuchepetsedwa, zomwe zimathandiza kuti kukula ndi m'lifupi mwa lens zichepetse," akufotokoza wopanga Myoungoh Ki wochokera kugawo la Samsung's System LSI. "Izi zimatha kuthetsa zinthu zomwe zimasokoneza kapangidwe ka chipangizocho, monga kamera yotuluka, komanso kuchepetsa kugwiritsa ntchito mphamvu," adatero. anawonjezera.

Ngakhale ma pixel ang'onoang'ono amalola kuti chipangizocho chikhale chocheperako, chofunikira ndikusunga mawonekedwe azithunzi. ISOCELL HP3, yopangidwa pogwiritsa ntchito umisiri wamakono, yokhala ndi 12% yaying'ono ya pixel kuposa yoyamba ya Samsung 200MPx photosensor. ISOCELL HP1, imatha kuchepetsa mawonekedwe a kamera mu foni yam'manja mpaka 20%. Ngakhale kukula kwake kuli kocheperako, ISOCELL HP3 yapangidwa pogwiritsa ntchito ukadaulo womwe umakulitsa luso lawo la Full Well Capacity (FWC) ndikuchepetsa kutayika kwa chidwi. Kukula kwakung'ono kwa pixel ndikwabwino popanga zida zazing'ono, zocheperako, koma zimatha kupangitsa kuwala kochepa kulowa mu chipangizocho kapena kusokoneza ma pixel oyandikana nawo. Komabe, ngakhale ndi izi, Samsung adatha kupirira, ndipo malinga ndi Ki, ndi chifukwa cha luso laukadaulo la chimphona cha Korea.
Zithunzi
Samsung yakwanitsa kupanga makoma a thupi pakati pa ma pixel omwe ndi ochepa komanso ozama pogwiritsa ntchito teknoloji ya Full Depth deep trench isolation (DTI), yomwe imatsimikizira kugwira ntchito kwakukulu ngakhale pa kukula kwa ma microns 0,56. DTI imapanga gawo lakutali pakati pa ma pixel omwe amakhala ngati khoma lotchingira kuti ateteze kutayika kwa kuwala ndikuwongolera magwiridwe antchito. Wopanga Sungsoo Choi wa Samsung's Semiconductor R&D Center amafananiza ukadaulo ndi kumanga chotchinga chopyapyala pakati pa zipinda zosiyanasiyana mnyumba. "M'mawu a anthu wamba, ndizofanana ndikuyesera kupanga khoma locheperako pakati pa chipinda chanu ndi chipinda choyandikana nacho popanda kusokoneza mulingo woletsa mawu," Iye anafotokoza.
Mutha kukhala ndi chidwi ndi
Ukadaulo wa Super Quad Phase Detection (QPD) umalola ma pixel onse 200 miliyoni kuyang'ana kwambiri pakukulitsa kukula kwa ma pixel a autofocus mpaka 100%. QPD imapereka ntchito yofulumira komanso yolondola kwambiri ya autofocus pogwiritsa ntchito lens imodzi yopitilira ma pixel anayi, kulola kuyeza kwa magawo onse akumanzere, kumanja, pamwamba ndi pansi pa mutu womwe ukujambulidwa. Sikuti autofocus ndiyolondola kwambiri usiku, koma kusamvana kwakukulu kumasungidwa ngakhale kulowetsedwa mkati. Pofuna kuthana ndi vuto la kusawoneka bwino kwazithunzi m'malo opepuka, Samsung idagwiritsa ntchito luso lamakono la pixel. "Tidagwiritsa ntchito luso lathu laukadaulo la Tetra2pixel, lomwe limaphatikiza ma pixel anayi kapena khumi ndi asanu ndi limodzi oyandikana kuti akhale ngati pixel imodzi yayikulu m'malo opepuka," Choi anatero. Ukadaulo wotsogola wa pixel umapangitsa kuti zitheke kuwombera makanema mu 8K resolution pa 30 fps ndi 4K pa 120 fps osataya mawonekedwe.
Ki ndi Choi adanenanso kuti adakumana ndi zopinga zingapo pakupanga chithunzithunzi chatsopano (makamaka pakukhazikitsa ukadaulo wa DTI, womwe unagwiritsidwa ntchito ndi Samsung kwa nthawi yoyamba), koma adagonjetsedwa chifukwa cha mgwirizano wa matimu osiyanasiyana. Ngakhale kuti chitukuko chinali chovuta, chimphona cha ku Korea chinayambitsa sensa yatsopano pasanathe chaka chimodzi chilengeze sensa yake yoyamba ya 200MPx. Kodi foni yam'manja yomwe idzayambikemo sichidziwikabe mpaka pano.
