Abstract
A dynamic vision sensor (DVS) including a plurality of substrates electrically connected to one another and stacked vertically includes a photoelectric conversion device configured to generate charges in response to incident light from an external environment that is external to the DVS sensor, a bipolar junction transistor (BJT) device including a base connected to the photoelectric conversion device and configured to output a current based on amplifying a current output from the photoelectric conversion device, and a DVS pixel circuit that detects a change in intensity of the incident light and to output an event signal based on the current. The photoelectric conversion device is on a first substrate among the plurality of substrates. At least part of the DVS pixel circuit is on a different substrate from the first substrate among the plurality of substrates.
