The Galaxy S9
are the first top-shelf smartphones with variable aperture cameras, oscillating between f/1.5 and f/2.4 aperture depending on the light conditions. Samsung is so proud of its new creation, and we did indeed find it useful in extreme low-light shots, that it outed the infographic you see here to explain to us how eighteen years of cell phone camera innovation got it to the top of the pile.
Samsung has a brand new camera sensor in the Galaxy S9
and S9+, and it has already detailed all the 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.
It's a bit cumbersome to use in practice, and requires some forward planning, but it's nice to know the option is there when you need it. Check out Samsung's journey towards the very best in mobile photography.
