A method for acquiring intensity images through a dynamic vision sensor is provided, the method including resetting an inner state of each of a plurality of pixels in the dynamic vision sensor to a predetermined value; receiving from at least one of the plurality of pixels an event signal based on a change in its inner state indicative of a difference in amount of light incident upon the at least one of the plurality of pixels versus that corresponding to the predetermined value; and integrating over a time period the received event signal for the at least one of the plurality of pixels to determine the intensity of light incident upon the at least one of the plurality of pixels.
