Abstract
Provided are pixels, devices, systems, and methods relating to active pixel sensor in which each active pixel puts out a signal that represents a temporal differential. The output of the active pixel represents a comparison or difference between successive frames. The differential can represent the state of the sensor element in the pixel at the end of one frame compared to the state of the sensor element of the frame, at the end of the prior frame.
