摘要：
A light source device includes a first light source configured to emit light within a first wavelength band, a light-source light production section configured to sequentially produce light-source light of a plurality of colors at predetermined frequency by using light emitted by the first light source, a second light source configured to emit light within a second wavelength band different from the first wavelength band, and a light source control section configured to control drive timing for each of the first and second light sources such that a light emission period for light-source light using light emitted by the second light source is positioned between light emission periods for the light-source light of the plurality of colors produced by the light-source light production section and that the light-source light using light emitted by the second light source has a frequency higher than that of the light-source light production section.
