1. An apparatus for recognizing motion using an event-based vision sensor, the apparatus comprising:

  • a vision sensor configured to sense a movement-occurring part and output events;

    a movement type determiner configured to determine a type of movement using a frequency of occurrence of the events outputted through the vision sensor;

    a first motion determiner configured to track a movement trajectory of the movement-occurring part and determine a motion pattern based on the tracked movement trajectory in response to a result of the movement type determiner indicating a small movement;

    a second motion determiner configured to determine a direction of movement in which an object moves based on the output events in response to a result of the movement type determination indicating a large movement; and

    a motion controller configured to output a control instruction to control a device based on the motion pattern determined by the first motion determiner or the movement direction determined by the second motion determiner.
