It additionally improves focusing in low-light conditions and on fast-moving objects.
The Samsung ISOCELL GN2 additionally options what Samsung payments as staggered-HDR, utilizing rolling shutters to seize photos in numerous exposures. In comparison with the real-time HDR utilized in most sensors, Samsung says it makes use of 24% much less energy whereas nonetheless delivering vivid highlights and darkish shadows.
The 50MP sensor additionally has different methods, like four-pixel-binning underneath tough lighting circumstances or utilizing a mosaic algorithm to create a 100MP image.
