Abstract: A light source device includes light sources, a light output unit, optical filters, temperature sensors detecting current temperatures of the sources, light quantity sensors detecting current light quantities of light beams before traveling through the filters, a storage, and a processor. The storage stores first correlation information between the temperatures of the sources and spectral information and second correlation information between the spectral information and light quantity of light at the unit. The processor is configured to calculate a variation in the spectral information based on each current temperature and the first information, calculate a variation in the light quantity of the light at the unit caused by a change in the spectral information based on the variation in the spectral information and the second information, and calculate a light-quantity correction amount for each of the sources based on the variation in the light quantity and the current light quantity.

Abstract: An endoscope device includes a processor configured to calculate light source control information based on first information regarding a scope and second information regarding a light source device, and to control a light source of the light source device based on the light source control information. The second information includes a ratio of an amount of light emitted from a distal end of a reference scope to an amount of light emitted from the light source device to the reference scope.
