Samsung's new 50MP ISOCELL GN2 sensor promises faster auto-focus

23 February 2021 0

Samsung has introduced a new 50MP ISOCELL GN2 camera sensor, which offers bigger pixels and a larger sensor size than its predecessor. It is 1/1.2-inch in size and accommodates bigger (1.4 microns-sized) pixels.

The key highlights of the new GN2 sensor are improved auto-focusing through Dual Pixel Pro technology, powerful staggered HDR, Smart ISO Pro. The sensor supports full HD videos at 480 frames-per-second (fps) or 4K at 120fps, and 8K at 24fps videos as well. The GN2 also supports pixel-binning to deliver 12.5MP pictures.

Samsung touts the ISOCELL GN2 is Samsung’s first image sensor to offer Dual Pixel Pro, an upgraded version of phase-detection autofocus. Samsung touts it to be the company’s “most advanced phase-detection auto-focus solution yet.”

It is the solution for ultra-fast auto-focusing. This doesn’t only split the pixels vertically, as with Dual Pixel, but also diagonally. According to Samsung, the diagonal cut allows the sensor to get in focus quickly. Samsung also mentions that low-light focusing and tracking of moving objects have improved as well.

A larger pixel size allows more light to pass through and it is pretty apt for low-light conditions. According to Samsung, in mixed-light conditions, the GN2 maximizes its dynamic range with a staggered-HDR feature. The latter ensures that rich and vivid details are being captured even in dark shadows. Samsung claims this combination allows shooting high-contrast sights. The staggered-HDR support also reduces the energy consumption of a sensor by up to 24% compared to its predecessor’s real-time HDR mode.

The Smart ISO Pro helps in creating high dynamic range images with fewer motion artifacts. In extremely low light, Smart ISO Pro can process multiple frames in high ISO and offer better night photography.

Samsung announces that the ISOCELL GN2 is currently in mass production. This suggests the sensor will soon make its way to some of the most-awaited smartphones. According to the tipster Ice Universe, the Xiaomi Mi 11 Ultra will use Samsung's newest ISOCELL GN2 sensor.
