Abstract: 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.
