ENDOSCOPE APPARATUS
First Claim
1. An endoscope apparatus comprising:
- an endoscope insertion portion configured to be inserted into a subject;
a light source section that supplies light to the endoscope insertion portion; and
a light source control section, whereina first irradiation portion that radiates white light onto the subject, a second irradiation portion that radiates to the subject narrow bandwidth light having a narrower wavelength bandwidth than the white light, and an observation window that is used to observe the subject are disposed on a leading end surface of the endoscope insertion portion,each of the first and second irradiation portions includes a pair of irradiation windows for emitting lights therefrom,a straight line passing through a center point of the observation window and bisecting the leading end surface of the endoscope insertion portion is defined as a boundary line,the pair of irradiation windows of the first irradiation portion are disposed on the leading end surface on both sides of the boundary line,the pair of irradiation windows of the second irradiation portion are disposed on the leading end surface on the both sides of the boundary line, andthe light source control section is configured to individually change spectra of the lights radiated from the respective irradiation windows of the second irradiation portion.

Abstract
A first irradiation portion that radiates white light onto a subject, a second irradiation portion that radiates narrow bandwidth light having a narrower wavelength bandwidth than the white light, and an observation window used to observe the subject are respectively disposed on a leading end surface of an endoscope insertion portion. Each of the first and second irradiation portions includes a pair of irradiation windows for emitting light therefrom. A straight line passing through a center point of the observation window and bisecting the leading end surface is defined as a boundary line. The pair of irradiation windows of the first irradiation portion are disposed on both sides of the boundary line. The pair of irradiation windows of the second irradiation portion are disposed on the both sides of the boundary line. Spectra of lights radiated from the irradiation windows of the second irradiation portion can be changed individually.
