Abstract

A light source device for an endoscope comprises a light source unit and a light source controller. The light source unit has LEDs independently emitting light of respective different colors, and emits first multicolor spectrum light having a first multicolor spectrum, into which the light from the LEDs is combined. The light source controller makes a light quantity integral of the first multicolor spectrum light in a first wavelength band equal to a light quantity integral of continuous-spectrum light in the first wavelength band and makes a light quantity integral of the first multicolor spectrum light in a second wavelength band equal to a light quantity integral of the continuous-spectrum light in the second wavelength band. The continuous-spectrum light includes at least a part of a wavelength band of light emitted from a white light source. The second wavelength band is different from the first wavelength band.
