1. A light outputting device comprising:
a light source configured to output a light to an object;
a receiver configured to receive a light being reflected from the object;
a memory configured to store an information on a reference area of the object recognized in a normal state according to a distance between the light source and the object; and
a processor configured to control an output of the light source by comparing a recognition area of the object recognized by the receiver with the reference area,
wherein the processor controls the output of light to be inversely proportional to a size of the recognition area.
