Korean tech loj heev Samsung tshaj tawm 50-megapixel koob yees duab sensor dubbed ISOCELL GN2. Lub ntsuas yog yog kev hloov kho ntawm xyoo tas los ISOCELL GN1, uas tau tshaj tawm nrog ceev dua autofocus. Thaum lub GN2 tshiab tseem khaws cia 50MP sensor loj me, nws muaj cov pixels loj dua li ntawm kev siv lub zog. Lub sensor kuj los nrog tus tshiab theem nrhiav kom tau autofocus (PDAF) dubbed Dual Pixel Pro. 
ISOCELL GN2 muaj lub pixel loj ntawm 1,4 μm thiab lub zog loj ntawm 1 / 1,12 nti, uas yog qhov loj tshaj plaws uas koj tuaj yeem nrhiav hauv lub xov tooj ntawm lub xov tooj. Samsung thov tias 1,4μm loj loj pixel tso cai rau "cov duab ntxaws ntxaws ntawm cov teeb tsa ib txwm muaj." Lub sensor kuj siv plaub-pixel binning technology kom ua tiav pixel loj ntawm 2,8 microns rau cov duab zoo nyob hauv qhov chaw qis teeb pom kev zoo.
Ntxiv rau, Samsung lub sensor tshiab muaj peev xwm los ntes 100-megapixel duab los ntawm kev rov ua cov xim pixels siv dab tsi Samsung hu ua "ntse remosaic algorithm." Nws ua haujlwm zoo li no: lub sensor ntes peb txheej txheej ntawm 50 MP hauv ntsuab, xiav thiab liab, uas tom qab ntawd yog superimposed, ntsuas thiab ua ke los tsim cov duab siab.
Lwm qhov tseem ceeb ntawm ISOCELL GN2 yog Phase Detection Autofocus (PDAF), uas Samsung tau muab npe hu ua Dual Pixel Pro. Nws yog thawj lub sensor nrog qhov zoo li no thiab suav hais tias yog kev tshaj tawm ntawm Samsung PDAF tov. Cov thev naus laus zis cais ntsuab pixels dav ntawm kev sib cais ntawm cov kab sib cais liab, ntsuab thiab xiav pixels. Qhov no tso cai rau cov saum thiab hauv qab los nyeem cov qib sib txawv ntxiv rau sab lauj thiab sab xis. Yog li, autofocus tau nrawm thiab raug txawm tias nyob rau hauv cov kev mob tshwm sim xws li lub teeb uas tsis muaj zog lossis cov ncauj lus txav ceev.
Samsung hais tias lub koob yees duab sensor twb tau ntau lawm. Tsis muaj qhov qhia tau tias thaum twg peb yuav pom nws hauv smartphones, tab sis thaum twg nws tshwm, lub sensor yuav pom Smart ISO Pro, uas tsim cov duab HDR instant nrog cov kev tawm suab tsawg dua. Lub sensor kuj txhawb nqa 1080p cov video hauv 480fps lossis 4K @ 120fps.
