Abstract
A light source apparatus includes: a first light source unit including a plurality of light sources arranged therein, the plurality of light sources each emitting illuminating light in a first wavelength band; a second light source unit including a plurality of light sources arranged therein, the plurality of light sources each emitting illuminating light in a second wavelength band; an in-light source light guiding channel that guides the light emitted from the first light source unit and the light emitted from the second light source unit to a proximal end-side input end of a light guiding channel in an endoscope; and a light source control section that, based on endoscope information from an endoscope information storing section, divides the plurality of light sources in the first light source unit into a first light source group, light from which enters a vicinity of an optical axis of the proximal end-side input end of the light guiding channel in the endoscope, and a second light source group in a periphery of the first light source group, and divides the plurality of light sources in the second light source unit into a third light source group, light from which enters the vicinity of the optical axis of the proximal end-side input end of the light guiding channel in the endoscope, and a fourth light source group in a periphery of the third light source group, and performs control to decrease an output of the second light source group to be lower than an output of the first light source group and decrease an output of the fourth light source group to be lower than an output of the third light source group.
