An event detecting device may include an event signal generator configured to output a plurality of event signals, each including a first data and a second data having mutually complementary attributes and respective address data indicating positions of pixels having output the first data and the second data, a data manager configured to store one of the first data and the second data of a first one of the plurality of event signals and the respective address data in a buffer as first sub data when only one of the first data and the second data of the first one of the plurality of event signals includes the event information, and an output signal generator configured to generate an output signal using the first sub data and a second sub data when the second sub data, different from the first sub data, is stored in the buffer.

Event detecting device including an event signal generator and an output signal generator configured to generate an output signal by combining event signals

A dynamic vision sensor includes a pixel unit, including a plurality of pixels outputting an activation signal in response to dynamic input, a first reading unit outputting a first signal, based on the activation signal, a second reading unit outputting a second signal, based on the activation signal, an event counter counting the number of events generated, based on the activation signal, and generating and outputting a selection signal, based on the number of events, and a selecting unit outputting one of the first signal and the second signal, based on the selection signal.
