Patent ID: 8564651

Claim:
An endoscope apparatus including: an endoscope that includes an illumination optical system having at least one of a plurality of fluorescent substance; and a light source unit that is connected to the endoscope, includes a plurality of semiconductor light emitting elements having different central light emission wavelengths, and supplies light from the semiconductor light emitting elements to the illumination optical system; the endoscope system comprising: a multiplexer, unit that multiplexes the lights output from the plurality of semiconductor light emitting elements; a central wavelength converting unit that controls a light emission amount ratio of the plurality of semiconductor light emitting elements and converts the central wavelength of the light multiplexed by the multiplexer unit; wherein the central wavelength converting unit includes a wavelength conversion table in which the central wavelength of the light formed by multiplexing the lights emitted from the plurality of semiconductor light emitting elements is obtained on the basis of information of the light emission amounts and the central light emission wavelengths of the plurality of semiconductor light emitting elements, and the light emission amount ratio of the semiconductor light emitting elements is determined by referring to the wavelength conversion table.
