“…It has to be noted that the total noise value is a complex mixture of several noise sources of lens system, pixel size, sensor technology and manufacturing, image processing pipeline, ISO speed, exposure time, RAW conversion. Noise scales strongly with pixel size, becoming ugly in compact digital cameras and camera phones with tiny sensors, especially at high ISO speeds or in dim light, and affected by sensor technology and manufacturing quality (Peltoketo, 2015). The noise amount can be partially controlled by camera parameters, like ISO speed and exposure time, and denoising algorithms.…”
