英文摘要	In an endoscope system including: a light emission unit emits laser light as illumination light or excitation light; a light guide unit guides the illumination light or the excitation light to an object; and an image pickup unit picks up a normal image formed with reflection light generated by reflection of the illumination light from the object or a fluorescence image emitted from the object in response to the excitation light. The laser light is multiaxial-mode laser light, or the light emission unit includes a plurality of laser-light sources which emit single-axial-mode laser beams having different wavelengths or phases. Alternatively, a vibration unit which vibrates the light guide unit is provided, or a high-frequency signal is superimposed on a driving current of the light emission unit, so that the wavelength of the laser light is shifted among a plurality of values.
