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.

Abstract: An endoscope apparatus enables observation using reflected light of white light and observation using fluorescence, and includes: an insertion portion configured to be insertable into a subject; an objective optical system; a transmitting optical system; a camera unit; an optical splitter configured to split light exiting through the transmitting optical system; an optical filter disposed in the transmitting optical system or the camera unit, the optical filter being configured to transmit the reflected light of the white light and the fluorescence and block the reflected light of the excitation light; a first image pickup device for picking up an image of the reflected light of the white light exiting through the optical filter and the optical splitter; and a second image pickup device for picking up an image of the fluorescence exiting through the optical filter and the optical splitter.
