Abstract: An endoscope light source apparatus includes a first light source section that emits first light, a second light source section that emits second light, and an optical path combiner that combines an optical path of the first light and an optical path of the second light. The etendue of the first light source section is smaller than the etendue of the second light source section. The optical path combiner has an optical deflection surface that deflects the second light, and has an aperture that allows the first light to pass through it within an area of the optical deflection surface. The optical path combiner deflects the second light so that a center axis of the optical path of the second light deflected by the optical deflection surface corresponds to a center axis of the optical path of the first light that has passed through the aperture.

Abstract: An observation apparatus includes an imager, a light source unit, an image processor and a light intensity adjusting section. The imager includes types of elements which generate a first signal when the elements receive light included in a sensitivity region. The light source unit includes light sources to emit narrow spectrum light, wavelengths of the light being different from one another and being set so that at least one of the wavelengths is included in each of the sensitivity regions. The image processor generates display data indicating a color image on the basis of the image data. The light intensity adjusting section separately adjusts respective light intensity of the light sources.

Abstract: A subject observation system includes a light source and an image obtaining unit. The light source emits observation light including a spectral component of a wavelength and applies the light to a subject. The image obtaining unit images reflected light from an irradiation region of the subject to which the light has been applied and obtains at least two observation images in different wavelength regions based on image signals corresponding to a blue region, a green region and a red region. The light includes components of light emission spectra in the regions. The light emission spectrum in the blue region is smaller in a wavelength region in which absorption intensity for a specific observation target in the subject is relatively low than in other regions.

Abstract: A light source apparatus includes an optical illumination unit that converts optical characteristics of primary light emitted from a light source unit and emits secondary light different from the primary light; and an adapter unit that outwardly emits illumination light generated based on the secondary light emitted from the optical illumination unit and that is attachable to/detachable from the optical illumination unit. A radiation angle control member converts a traveling direction of the secondary light so that the secondary light allowed to emit from a light conversion member toward the radiation angle control member in the secondary light allowed to emit from the light conversion member travels toward the adapter unit through the secondary light emit portion.

Abstract: An endoscope observation method includes irradiating first and second narrowband light to an observation object. The first and second narrowband light have wavelengths at which absorbances of first and second characteristic substances related to a predetermined state of the observation object and contained in the observation object are mutually different. The method also includes performing imaging by use of reflected light of the first and second narrowband light from the observation object to obtain first and second image data, and forming a characteristic substance presence image regarding the presence of the first and second characteristic substance, on the basis of characteristic amounts of the first and second characteristic substances contained in the first and second image data.
