Abstract

A light source system capable of controlling a light emission amount of a light source section more accurately while keeping manufacturing costs low is provided. The light source system includes a light source, a light-sensing device detecting light from the light source, a calculation means, and a light source control means. The calculation means calculates a net light amount by subtracting a measurement environment component from a light amount detected by the light-sensing device. The measurement environment component is independent of a lighting state in the light source. The light source control means controls the light source on the basis of the net light amount obtained by the calculation means.
