Abstract
A light source device which causes a sufficiently bright subject image to be obtained is provided. The light source device includes a first light-emitting diode-which generates illumination light to be applied to a subject, a second light-emitting diode-which generates illumination light with wavelength different from the illumination light generated from the first light-emitting diode-, and a light-emitting diode drive control sectionwhich independently controls integrated output values (light emission intensities, light emission periods) of the first light-emitting diode-and second light-emitting diode-in synchronism with image pickup timing at which the subject is photographed.
