Abstract: A light source system includes a normal light source apparatus provided with a light source controller and a light source apparatus for specific light provided with a specific light controller. In a state where communication is enabled, the light source controller adjusts an emission intensity of the normal light, generates a light amount control signal that makes the normal light and the specific light have a predetermined light amount ratio, and sends the light amount control signal to the light source apparatus for specific light. The specific light controller adjusts an emission intensity of the specific light based on the received light amount control signal.
