Samsung Galaxy S9+ Cameras

TechInsights publishes an article on Galaxy S9+ reverse engineering including its 4 cameras - a dual rear camera, a front camera and an iris recognition sensor:

"We are excited to analyze Samsung's new 3-stack ISOCELL Fast 2L3 and we'll be publishing updates as our labs capture more camera details.

Samsung is not first to market with variable mechanical apertures or 3-layer stacked image sensors, however the integration of both elements in the S-series is a bold move to differentiate from other flagship phones.

The S9 wide-angle camera system, which integrates a 2 Gbit LPDDR4 DRAM, offers similar slo-mo video functionality with 0.2 s of video expanded to 6 s of slo-mo captured at 960 fps. Samsung promotes the memory buffer as beneficial to still photography mode where higher speed readout can reduce motion artifacts and facilitate multi-frame noise reduction.

iFixit reverse engineering report publishes nice pictures showing a changing aperture on the wide-angle rear camera:

  1. I think the slow motion record time is .6 sec not 6

    I just had the luxury to check out the Samsung S9 camera. Amazing performance, especially in dark environments. The camera was demonstrated in a box, shielded from outside light and with a very faint illumination. Of course one needs to be careful, because my own eyes were adapted to the strong evironment light and you never know how much near-IR light is still going to the sensor. But I also checked the camera with my tumb on the lens.
    But despite these "Warning Signs", great performance Mr./Mrs. Samsung !!!
