An endoscope apparatus includes: an image pickup portion that, with respect to return light including a plurality of wavelength band components generated accompanying irradiation of illuminating light onto an object, receives and picks up an image of the return light with spectral sensitivities that vary for each color component and a correction processing portion that performs correction processing with respect to a spectroscopic spectral distribution of each color component included in an image of the object obtained as a result of the image pickup portion picking up the image of the return light and an image separation processing portion that, based on a result of the correction processing, performs processing that separates the image of the object into each wavelength band component included in the return light.
