What Is Noise Reduction in Digital Images?

The digital sensor in your phone or camera is made from millions of small photosites. Each photosite corresponds to one pixel in the final image. When light hits a photosite, it creates an electric charge. The more light that hits the photosite, the stronger the charge created, and the brighter the pixel in the final image.
