Samsung tau tshaj tawm tshiab 200MPx yees duab sensor ob peb lub lis piam dhau los ISOCELL HP3. Qhov no yog lub sensor nrog lub pixel me tshaj plaws puas tau. Tam sim no, Korean tech loj heev tau tham txog nws txoj kev txhim kho los ntawm cov neeg tsim khoom los ntawm System LSI division thiab Semiconductor R&D Center.
Ib qho duab sensor (lossis photosensor) yog lub kaw lus semiconductor uas hloov lub teeb uas nkag mus rau hauv lub cuab yeej los ntawm lub koob yees duab lens rau hauv cov teeb liab digital. Cov duab sensors tau tsim rau hauv txhua yam khoom siv hluav taws xob uas muaj lub koob yees duab, xws li cov koob yees duab digital, laptops, tsheb thiab, tau kawg, smartphones. ISOCELL HP3, qhia los ntawm Samsung thaum Lub Rau Hli, yog cov duab thaij duab uas muaj 200 lab 0,56 micron pixels (kev lag luam qhov pixel me tshaj plaws) hauv 1/1,4 "optical hom.
"Nrog rau cov pixel me me, lub cev loj ntawm lub sensor thiab module tuaj yeem txo qis, uas tseem tso cai rau qhov loj thiab dav ntawm lub lens kom txo," piav qhia tus tsim tawm Myoungoh Ki los ntawm Samsung's System LSI faib. "Qhov no tuaj yeem tshem tawm cov ntsiab lus uas cuam tshuam los ntawm cov cuab yeej tsim, xws li lub koob yees duab protruding, nrog rau txo qis kev siv hluav taws xob," nws ntxiv.
Cov duab thaij duab
Thaum cov pixels me me tso cai rau cov cuab yeej ua kom yuag, qhov tseem ceeb yog tswj cov duab zoo. ISOCELL HP3, tsim los siv cov thev naus laus zis thev naus laus zis, nrog 12% pixel me me dua li Samsung thawj 200MPx photosensor ISOCELL HP1, tuaj yeem txo qhov chaw ntawm lub koob yees duab hauv lub xov tooj ntawm tes los ntawm 20%. Txawm hais tias qhov me me pixel loj, ISOCELL HP3 tau tsim los siv thev naus laus zis uas ua kom lawv lub peev xwm puv puv (FWC) thiab txo qis kev poob siab. Cov pixel me me yog qhov zoo tagnrho rau kev tsim cov khoom me me, slimmer, tab sis tuaj yeem ua rau lub teeb tsawg dua nkag mus rau hauv lub cuab yeej lossis cuam tshuam ntawm cov pixels nyob sib ze. Txawm li cas los xij, txawm tias nrog qhov no, Samsung muaj peev xwm tiv taus, thiab raws li Ki, nws yog ua tsaug rau cov cuab yeej thev naus laus zis ntawm Korean loj heev.
Cov duab thaij duab
Samsung tau tswj hwm los tsim cov phab ntsa ntawm lub cev ntawm cov pixels uas nyias thiab sib sib zog nqus siv Full Depth sib sib zog nqus trench cais (DTI) thev naus laus zis, uas lav kev ua haujlwm siab txawm tias qhov loj ntawm 0,56 microns. DTI tsim ib qho kev sib cais ntawm cov pixels uas ua raws li cov phab ntsa insulating los tiv thaiv lub teeb poob thiab txhim kho kev ua haujlwm kho qhov muag. Tus tsim tawm Sungsoo Choi ntawm Samsung's Semiconductor R&D Center piv cov thev naus laus zis los tsim cov txheej txheem nyias nyias ntawm cov chav sib txawv hauv ib lub tsev. "Nyob rau hauv layman cov ntsiab lus, nws yog tib yam li sim tsim ib tug nyias phab ntsa ntawm koj chav tsev thiab chav nyob ib sab ntawm lub qhov rooj yam tsis muaj kev cuam tshuam rau theem ntawm soundproofing," nws piav.
Koj tuaj yeem txaus siab rau
Super Quad Phase Detection (QPD) thev naus laus zis tso cai rau tag nrho 200 lab pixels tsom los ntawm kev ua kom muaj zog ntawm autofocus pixels rau 100%. QPD muaj kev ua haujlwm nrawm dua thiab muaj tseeb dua autofocus los ntawm kev siv ib lub lens tshaj plaub pixels, tso cai rau kev ntsuas ntawm txhua theem sib txawv ntawm sab laug, sab xis, sab saum toj thiab hauv qab ntawm cov ncauj lus tau yees duab. Tsis tsuas yog autofocus yog qhov tseeb dua thaum hmo ntuj, tab sis qhov kev daws teeb meem siab tau khaws cia txawm tias zoomed hauv. Txhawm rau daws qhov teeb meem ntawm cov duab tsis zoo hauv qhov chaw tsis muaj teeb pom kev zoo, Samsung siv thev naus laus zis pixel tshiab. "Peb tau siv qhov kev txhim kho ntawm peb cov cuab yeej Tetra2pixel thev naus laus zis, uas sib txuas plaub lossis kaum rau lub pixels uas nyob ib sab los ua ib qho pixel loj hauv qhov chaw qis qis," Choi hais. Kev txhim kho pixel thev naus laus zis ua rau nws tuaj yeem tua cov yeeb yaj kiab hauv 8K daws teeb meem ntawm 30 fps thiab hauv 4K ntawm 120 fps yam tsis tau poob qhov kev pom.
Ki thiab Choi kuj tau hais tias lawv tau ntsib ntau yam teeb meem hauv kev txhim kho cov duab thaij duab tshiab (tshwj xeeb yog kev siv DTI thev naus laus zis, uas tau siv los ntawm Samsung thawj zaug), tab sis lawv tau kov yeej ua tsaug rau kev koom tes ntawm ntau pawg. Txawm hais tias xav tau kev txhim kho, Kaus Lim Kauslim tau tshaj tawm lub sensor tshiab tsawg dua ib xyoos tom qab tshaj tawm nws thawj 200MPx sensor. Lub xov tooj smartphone twg nws yuav nthuav tawm nyob rau hauv tseem tsis paub meej ntawm lub sijhawm no.
