Samsung unveils the new 12MP sensor that lets Galaxy S9 do its Super Slow Motion magic
by Daniel Petrov / Feb 26, 2018, 3:56 AM
Samsung has a brand new camera sensor in the Galaxy S9 and S9+, and it just detailed all of its specs, putting to rest all speculation how does it do the Super Slow Motion capture that allows its new flagships to record 720p clips with 960fps.
Basically, the new 12MP Samsung ISOCELL Fast 2L3, which is already in mass production (duh), has its own stack of fast DDR4 memory attached under the typical analog logic layer that processes the electric signal coming from the pixel array layer above it, into digital code. The 3-stack setup is needed because recording 960fps slow-motion video results in a gigantic amount of frames that have to be stored and process quickly, and sending them to the chipset to process, and storing them in the phone's regular RAM would gum up the speed required to record the Super Slow Motion footage that the S9 is capable of.
very similar solution for its own slow-motion solution since the Xperia XZ Premium, and does have the option in its new XZ2 and its Compact version, too. Samsung, however, is taking advantage of the third memory layer stacked directly onto the CMOS sensor further, by using it to also store imagery of fast-moving objects, avoiding the typical blur and jello effects that come with such capture.Sony uses a
In addition, the ultrafast sensor storage allows for 3-Dimensional Noise Reduction (3DNR) for brighter, noise-free pictures in low-light, and enhanced real-time HDR imaging, all aided by the record wide f/1.5 aperture on the Galaxy S9 and S9+, which on top of that is of a variable type, and can be shrunk to f/2.4 when there is enough light around. We already previewed the S9 camera with some samples from the MWC, and the results from Samsung's newest ISOCELL Fast 2L3 sensor are very encouraging.

lol the Emoji-stuff looks so cheap - everything else seems nice though.

I thought it all looked good (except for the purple phone).

To be honest, the whole "emoji" category is pretty useless, no matter how you put it. BTW: This adaptation has hand and fingers ... I wonder, can you make "middle finger" emoji? I'd buy that for a dollar!

Sony 960fps in FHD R.I.P Samung is old.

Sony only works for 0.1 second, Samsung works for 0.2 at 720p. S9 does capture 4k 120 fps and 1080p 480 fps though.

Sony also work for 0.2 second in 720p mode. And Samsung Galaxy S9 can't capture 4k in 120 fps yet (I knew you are going to argue that Exynos 9810 has such feature, but sadly, Samsung just disabled it in their S9). I do agree Samsung has implement a better way in slow motion compared to Sony by granting the feature with smart A.I to automatically captured the slow motion.

Yes, sony can do 0.2 seconds on 720p too. My comment just meant that the two phones are comparable in slow-mo capture and it's not a slam dunk by the Xperia. I would personally prefer 0.2 sec 720p over 0.1 second 1080p. The Anandtech article says that it does indeed do 4k 120. https://www.anandtech.com/show
Not sure whether it does have it or not, but pretty positive. Since it's saved as 4x slowed down 4k 30 fps, so it's not necessary for the SoC to support 4k 120 fps encoding or decoding.

The rest of the stuff(ARE Emoji and Super slow motion) probably be used very sparingly if at all by me. I'm more excited about shooting 4k@60fps and being able to slow that footage down in post for the highest quality slow motion videos along with regular 4k footage. That's the real gem here.
