An electronic apparatus includes: a detection sensor which detects a wave motion coming from an object present within a predetermined range and outputs a detection signal; an object detection unit which detects an object present within the predetermined range based on the detection signal output from the detection sensor; a gesture detection unit which detects a gesture according to the movement of the object based on the detection signal output from the detection sensor; and a detection resolution control unit which sets the detection resolution of the detection sensor to a first resolution when detecting the object present within the predetermined range, and sets the detection resolution of the detection sensor to a second resolution higher in resolution than the first resolution when detecting the gesture.
