1. A method of controlling an electronic device by recognizing movement of an object within a peripheral zone of field of view (FOV) of a camera, the method comprising:
obtaining, through the camera, at least one image comprising an image of the object;
dividing the obtained at least one image into a middle zone and a peripheral zone, wherein the middle zone comprises at least one middle image, and the peripheral zone comprises at least one edge image;
obtaining a first object image from the at least one edge image;
obtaining a second object image from the at least one middle image;
verifying the first object image by using the second object image;
determining the verified first object image as the image of the object serving as a subject of the movement;
extracting one or more feature points of the object that are within the peripheral zone from the image of the object serving as a subject of the movement;
recognizing a movement pattern of the object from among a plurality of movement patterns based on the extracted one or more feature points;
identifying an instruction corresponding to the recognized movement pattern of the object within the peripheral zone; and
controlling the electronic device based on the identified instruction.
