Abstract: An endoscope illumination light switching device includes a rotation body in which a plurality of holes including a first hole are formed in a circumferential direction and that switches a hole on an irradiation optical path through rotation, a drive device configured to rotationally drive the rotation body, a sensor, and a processor configured to control a stop position of the rotation body based on a detection signal from the sensor. The rotation body includes a first detection target shape portion corresponding to the first hole, and another detection target shape portion. The sensor outputs a detection signal in response to detection of each shape portion when the rotation body rotates.

Abstract: An endoscope apparatus includes: an imaging device; a light source device; a first processing circuit; and a second processing circuit. The light source device can emit first light and fourth light having peak wavelengths in a transmission wavelength band of the blue color filter, second light, and third light and fifth light having peak wavelengths in a transmission wavelength band of the red color filter. The light source device emits the third light in a first imaging frame and the fifth light in a second imaging frame. The first processing circuit generates a display image based on any one of a first image group including images corresponding to the third light and the fifth light and a second image group including an image corresponding to the fourth light, and outputs a remaining one of the first image group and the second image group to the second processing circuit.

Abstract: A light source device includes a first semiconductor light source, a second semiconductor light source, and a wavelength converter. The first semiconductor light source emits light in a first wavelength range. The second semiconductor light source emits light in a second wavelength range different from the first wavelength range. The wavelength converter absorbs the light in the first wavelength range to emit light in a third wavelength range different from either of the first wavelength range and the second wavelength range, and transmits the light in the second wavelength range substantially entirely.

Abstract: An endoscope apparatus includes an illuminator including: an emphasis light source that emits emphasis narrow band light whose peak or central wavelength is included in an emphasis wavelength range that includes a maximum wavelength taking a maximum value of an optical absorption spectrum of a diagnosis target substance or a largest wavelength taking a largest value of the spectrum in any of three color ranges; and a non-emphasis light source that emits non-emphasis narrow band light whose peak or central wavelength is included in a non-emphasis wavelength range that is a wavelength range not including the emphasis wavelength range of the color ranges. The illuminator further includes a light quantity ratio changing section that changes a light quantity ratio between the emphasis and non-emphasis narrow band light.

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.
