Abstract
A light source apparatus includes a first light source, a second light source configured to emit light with a different wavelength than that of the first light source; and a controller for controlling each of the first and second light sources. The controller provides a control such that the second light source takes a longer time from a lighting start to a lighting completion than the first light source, and the second light source starts lighting earlier than the first light source.
