Abstract
The present disclosure relates to an event-driven sensor comprising: a pixel array (102); a column readout circuit (104) comprising, for each of the column output lines, a column register cell (108) configured to activate a column event output signal (addrx) when it receives a first token while the detection of an event is indicated on the column output line; and a row readout circuit (106) comprising, for each of the row output lines, or for each of a plurality of sub-groups of the row output lines, a row register cell (108) configured to activate a row event output signal (addry) when it receives a second token while an event is indicated on the row output line, or on one of the row output lines of the sub-group.
