What Electronic Image Noise Signatures Can Tell Us About Image Linearity and Camera Encoding
Electronic image noise is often categorized as an artifact of image capture which typically requires correction. There are several sources of electronic image noise that contribute to the overall total noise in an image. Some of the noise from specific sources, known as systematic noise, can be corrected for in-camera, but noise due to certain sources, like photon noise, persists after capture and increases with exposure. We study this relationship between exposure and noise and discover that this relationship reveals information about the linearity, or non-linearity of the image encoding.
