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: An illumination unit includes a light guide to guide primary light, a conversion member to convert the primary light into secondary light, and a holder holding an exit end of the light guide and the conversion member. The holder includes an entrance portion that the primary light enters, an exit portion to emit illumination light including the secondary light, and a fixing portion fixing the conversion member between the entrance portion and the exit portion in a direction of a central axis of the primary light. The fixing portion is arranged in a planar region perpendicular to the central axis of the primary light and on an inner peripheral face of the holder. The conversion member is in contact with the fixing portion.

Abstract: A light source apparatus includes a light conversion unit converting primary light into secondary light. The light conversion unit includes a light conversion member, a holder and a reflection member. The holder includes an incidence portion through which the primary light enters and an exit portion through which at least part of the secondary light exits in a direction crossing an optical axis of the primary light. The light conversion member is arranged on the optical axis of the primary light. Part of the secondary light allowed to exit from the light conversion member in a direction different from a direction toward the exit portion is reflected by the reflection member and exited from the exit portion. The ratio of reentering to the light conversion member is reduced.

Abstract: An endoscope system includes a light source that emits illumination light, an image sensor that captures an image of an object toward which the illumination light is emitted, and a processor. The processor is configured to determine whether a fluid is present in the object. If the fluid is not present in the object, the processor switches to a first observation mode in which to illuminate the object by first illumination light. If the fluid is present in the object, the processor switches to a second observation mode in which to illuminate the object by second illumination light. The second illumination light includes is larger than the first illumination light in a relative ratio of long wavelength components.
