Abstract
The present disclosure relates to a dynamic vision sensor. The dynamic vision sensor comprises a pixel array, address event representations, and a control logic. The pixel array includes a plurality of dynamic vision sensor (DVS) pixels connected to a plurality of row lines and a plurality of column lines. Each of the DVS pixels is configured to output an event signal in response to a change in light. The address event representations are configured to select one of the plurality of column lines and obtain an event signal output from DVS pixels connected to the selected column line. The control logic is configured to generate image data, including an object capable of generating a movement using an event signal output from each of the plurality of DVS pixels. The control logic divides the plurality of DVS pixels into a plurality of groups and allocates different readout times to each of the plurality of groups.
