Electronic apparatus for recognizing user and controlling method thereof

An electronic apparatus comprising:

• a communication interface;
• a dynamic vision sensor (DVS) comprising a plurality of sensing elements;
• a memory including a database in which one or more images are stored;
• and
• at least one processor configured to:
• generate an event signal when a sensing element of the plurality of sensing elements detects a change in a light intensity,
• store information about a point in time when the change in the light intensity occurred in an event map based on the generated event signal as a time information, wherein the event map includes a plurality of map elements corresponding to the plurality of sensing elements,
• generate an image, in which a shape of an object is included, la displaying a specified value in pixels corresponding to each of the plurality of map elements, based on the time information which is stored in the event map,
• store a plurality of images generated under a specified condition, in the database, the plurality of images including a shape of a user,
• identify shapes of the user included in each of the plurality of images stored in the database, and
• generate shape information for recognizing the user based on the identified shapes.
