Abstract:
Provided is a method of correcting an error of an optical sensor including a light source and an image sensor, the method including emitting light to a material by driving the light source, acquiring an image of the material by the image sensor, and correcting an error of a distance between the light source and the image sensor of the optical sensor based on a gradation of the acquired image of the material.
