Abstract: A light source device includes a semiconductor light source that radiates light at a light quantity according to an applied current, a circuit that determines a current instruction value based on control information, first and second drive units, each of the units that is connected to the semiconductor light source and the circuit, and is capable of outputting, to the semiconductor light source, a current having magnitude corresponding to the current instruction value. The control information is set based on brightness of an image captured by an imaging element. When one of the first and second drive units is switched to the other, the circuit causes the other to start the current output after an elapse of a predetermined stop time period having a length at a predetermined ratio or less to a frame rate on the imaging element since a stop of the current output from the one.

Abstract: An endoscope light source device includes a light source to emit light, and a speckle reduction member to scatter the light. The reduction member has a surface including thickness variation to provide the light with an optical path difference. The device also includes a drive to move the reduction member, and a lens to condense the light passed through the reduction member onto a light guide of an endoscope. The surface of the reduction member has inclination of an average inclination angle. The average inclination angle is determined so that a light quantity loss rate of the entering light into the light guide by scattering of the reduction member and refraction of the lens has a positive value equal to or smaller than an effective allowable loss rate.
