Method of operating dynamic vision sensor system

Abstract

A method of operating a dynamic vision sensor system includes: obtaining event signals from a plurality of dynamic vision sensor pixels over a predetermined time period, wherein the event signals correspond to a measured change in light; obtaining original image data based on the event signals output by the plurality of DVS pixels and including a plurality of image pixels, wherein the plurality of image pixels respectively correspond to the plurality of dynamic vision sensor pixels; obtaining binary image data by binarizing pixel values of the plurality of image pixels; defining a plurality of pixel groups from the plurality of image pixels in the binary image data; and selecting a plurality of effective groups from among the plurality of pixel groups that represent the movement of an object.
