An electronic apparatus includes a processor configured to identify a first distance based on locations of first pixels that received the reflective light, and identify a second distance based on locations of the second pixels that received the reflective light, and calculate a difference between the first and second distances, and based on a distance acquired by the calculation and a moving distance of the electronic apparatus identified through the second sensor, identify whether the reflective light is reflective light reflected by an object or reflective light that was reflected on the object and then reflected again by another object.
