A light source unit emits excitation light, which causes a drug to be excited to emit chemical fluorescence, and reference light which has a wavelength range from a blue-light wavelength range to a red-light wavelength range. A color information acquisition section acquires a plurality of pieces of color information from fluorescence and reference image signals that are obtained from the image pickup of an object to be observed illuminated with the excitation light and the reference light. A color difference expansion section expands a color difference between a normal mucous membrane and a fluorescence region in a feature space formed by the plurality of pieces of color information.
