Abstract: An endoscope apparatus includes a spectroscopic section disposed on an optical axis of return light from an object irradiated with visible light, first excitation light and second excitation light including a longer wavelength than a wavelength of the first excitation light and configured to separate and emit the light of a second wavelength band other than light of a first wavelength band, a first excitation light cut filter configured to block a wavelength band of one of the first excitation light and the second excitation light included in the return light, and a second excitation light cut filter configured to block a wavelength band of another excitation light of the first excitation light and the second excitation light and a wavelength band of the visible light.

Abstract: An endoscope system includes a convex-portion specifying section that detects a convex portion in a picked-up image of a subject picked up by an image pickup section, and a convex-portion-size calculating section that detects a convex portion in a predetermined size range on the basis of information concerning the convex portion. An illumination section includes a plurality of illumination-light emitting sections that illuminate the subject with lights in bands different from one another from directions different from one another. The plurality of illumination-light emitting sections are provided on a distal end side inner circumferential surface of a cylindrical cap attached to the distal end of an insertion section of an endoscope to specify an image pickup range of the image pickup section.
