1. A method comprising:
generating a photocurrent with a photodetector in a two-dimensional array of photodetectors, the photocurrent representing radiation incident on the two-dimensional array of photodetectors from a scene;
converting the photocurrent into a digital signal with an analog-to-digital converter (ADC) in a two-dimensional array of ADCs;
storing a count value representing the digital signal in a modulo M counter operably coupled to the ADC; and
generating a representation of the scene having a dynamic range based on a product of M and a least significant bit of the at least one ADC.
