Abstract
Techniques described herein generally relate to digital imaging systems, methods and devices. In some example embodiments, a low light adaptive photoelectric imaging device may include a photoelectric transducer configured to receive and convert incident light into an electric charge that varies in response to an intensity of the received incident light. Some example imaging devices may also include circuitry coupled to the photoelectric transducer and configured to electrically float a potential at one or more terminals of the photoelectric transducer effective to cause the photoelectric transducer to amplify the electric charge according to a gain function that non-linearly varies relative to the intensity of the received incident light.
