Night Shot is also designed to combat digital noise, which are those ugly, grainy artifacts that show up in photos you take in the dark. Typically, the hardware solution to solving noise is to use a bigger sensor with bigger pixels that can capture more light from a scene, which cuts down on the need to amplify the signal. Night Sight, however, uses clever software strategies. For instance, the camera can analyze multiple frames and observe when noise appears in one frame but not the others. It realizes it’s an artifact and not part of the scene, which helps to eliminate it.
