Abstract

A merged frame-based and event-based image sensor pixel is provided, comprising a reverse-biased photodiode; a frame-based signal readout circuit connected to a cathode of the photodiode; and an event-based signal readout circuit connected to an anode of the photodiode. Light received in the photodiode causes the production of electrons and holes. The recombination current of the holes is continuously measured for producing the event-based signal.
