Samsung introduces the ISOCELL GN2, a 50MP camera sensor and a successor of ISOCELL GN1. This one has larger pixel sizes, enhanced energy utilization, and the all-new Phase-Detection Autofocus (PDAF) system dubbed as Dual Pixel Pro.
The type size translates to 1/1.12”, the largest in a smartphone yet together with pixels of 1.4μm size each courtesy of which the new sensor delivers exceptionally detailed photographs in regular settings. It simulates a 2.8μm pixel thereby leveraging the same old four-pixel-binning for better low light photography.
The ISOCELL GN2 re-arranges color pixel via what Samsung calls “an intelligent re-mosaic algorithm”, hence able to capture 100MP images, which are essentially a total of three 50MP layers in Green, Blue, and Red that are overlaid, upscaled, and merged in order to form a high-resolution photograph.
As for the Dual Pixel Pro feature, it’s quoted as Samsung’s most advanced PDAF tech, which splits the green pixels diagonally so that the top, right, bottom, and right can read phase differences rather than splitting all color pixels at once.
The sensor is expected to produce fast and accurate autofocus even in critical situations such as low-light environments or fast-moving objects whilst the likes of parallel and horizontal stripes are finally addressed. This means all future GN2 iterations will come with a faster focus lock.
The Samsung ISOCELL GN2 sensor also has Smart ISO Pro for HDR photography with even fewer motion-artifacts and video recording at 1080p @ 480 fps or 4K @ 120 fps. Its mass production has kicked off already.
