A review of IEEE P2020 noise metrics

Abstract

The IEEE P2020 Noise standard is built upon methodology that is discussed by other photography and camera standards. It includes extensions and adjustments to support operating modes and conditions that are relevant to automotive cameras. This work presents methods and procedures that are covered by the IEEE P2020 Noise standard to derive sensor-level and camera-level noise image quality factors from dark statistics, photon-transfer and signal-to-noise ratio curves, and signal falloff. Example implementations and experimental results are shown from work that was done with automotive cameras which were activated and tested under conditions that are relevant to automotive applications.
