摘要：
A light source device includes a first light source configured to emit light within a first wavelength band, a second light source configured to emit light within a second wavelength band, and a light source control section configured to control drive timing of the first light source with a first drive pattern, and to control drive timing of the second light source with a second drive pattern which is an inverted pattern of the first drive pattern of the first light source, 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 emitted by the first light source, and such that a frequency of the light-source light using light emitted by the second light source is higher than a frequency of light emitted by the first light source.
