ENDOSCOPE SYSTEM

摘要

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.

1. An endoscope system comprising:
an illumination section that radiates illumination light and illuminates a predetermined illumination range; an image pickup section that picks up an image of a predetermined image pickup range of a subject illuminated by the illumination section; a convex-portion specifying section that detects a convex portion in the picked-up image of the subject picked up by the 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 detected by the convex-portion specifying section, wherein the 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 image pickup section is attached to a distal end of an insertion section of an endoscope and includes an optical axis in an axial direction of the insertion section, and 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 the insertion section to specify an image pickup range of the image pickup section.
