Abstract:
1. A light source device comprising: a first light source configured to emit light in a first wavelength range; a light-source light generation section configured to generate light-source light of each of a plurality of colors by using the light emission of the first light source by time division; a second light source configured to emit light-source light of a second wavelength range different from the first wavelength range; a first control section configured to control (i) a drive timing of each of the first and second light sources, and (ii) the light-source light generation section such that the light-source light generated from each of the light-source light generation section and the second light source is cyclically generated; a detection section configured to detect a light intensity of the light-source light generated from each of the light-source light generation section and the second light source; a storage section configured to store therein (i) light intensity values of the light-source light generated from each of the light-source light generation section and the second light source detected by the detection section, and (ii) a target light intensity ratio; and a second control section configured to calculate a light intensity ratio of the light-source light detected by the detection section, and to adjust a light emission state of each of the first and second light sources such that the calculated light intensity ratio becomes equal to the target light intensity ratio.
