Data output device

A dynamic vision sensor comprising:

• an event array including a first sensing element group and a second sensing element group;
• a first event identifier configured to receive first event signals detected by the first sensing element group and to output first location information in response to the first event signals;
• a second event identifier configured to receive second event signals detected by the second sensing element group and to output second location information in response to the second event signals;
• and
• an event output interface configured to receive the first location information from the first event identifier, to receive the second location information from the second event identifier, and to output event information based on at least one of the first location information and the second location information,
• wherein the first sensing element group is independent from the second sensing element group,
• wherein the event output interface is configured to output the event information with a resolution of M×N,
• wherein the first sensing element group includes first unit cells located at intersections of first longitudinal axes and first lateral axes, a number of the first longitudinal axes corresponding to M/2 and a number of the first lateral axes corresponding to N/2,
• wherein the second sensing element group includes second unit cells located at intersections of second longitudinal axes and second lateral axes, a number of the second longitudinal axes corresponding to M/2 and a number of the second lateral axes corresponding to N/2,
• wherein a number of the first and second unit cells is (M×N)/2, and
• wherein each of the M and N is an integer greater than zero.
