The present disclosure relates to an endoscopy system. The endoscope system includes: a first light source unit which is installed on a substrate； a second light source unit which is installed on the substrate and which emits light when the first light source unit does not emit light； an optical unit through which the light of the first light source unit or the second light source unit passes； a light guide unit which induces the light which passed through the optical unit to the inside of a target object； an image sensing unit which senses the light reflected and reached from the target object and which converts the sensed light into an image signal； and an image signal processing unit which processes the image signal to display on a display unit.
