Samsung has announced the details of the ISOCELL GN2, its second-generation 50MP smartphone image sensor that features 1.4μm pixels, improved autofocus capabilities, better HDR capture and more.The 1/1.12-inch GN2 slightly increases the pixel size to 1.4μm, up from 1.2μm in its GN1 predecessor. For low-light scenes, the sensor can use four-pixel-binning that should simulate the light-sensitivity of 2.8μm pixels, albeit at the cost of resolution. If you’re looking for higher resolution, the GN2 has a new 100MP mode that uses an on-chip re-mosaic algorithm that combines three 50MP frames in red, green and blue to create a single upscaled 100MP image.
