Abstract
A method of correcting an error of an optical sensor which includes a light source and a detector, including adjusting a brightness of the light source to a preset brightness; controlling the light source to emit light to a preset material; acquiring preset material data corresponding to the emitted light and the preset material using the detector; and correcting, by using the acquired preset material data, an error of a distance between the light source and the detector based on a difference between a first amount of light received at a first point of the detector and a second amount of light received at a second point of the detector, or based on a gradation of an image obtained by the detector.
