Abstract: An endoscope system according to the present invention includes: an illumination light source that emits illumination light for illuminating an object; a therapeutic light source that emits therapeutic light for causing a photoreactive reagent accumulated in a treatment target site to react; a guide light source that emits guide light having a wavelength shorter than a wavelength band of the therapeutic light source; an imager that captures an optical image, the imager including an optical filter that cuts light in the wavelength band of the therapeutic light and transmits a part of white light, the guide light, and fluorescence emitted by the reagent; a controller that controls emission timings of the illumination light source, the therapeutic light source, and the guide light source; and an image processor that generates an image on the basis of an optical image obtained by light emitted from the illumination light source, the therapeutic light source, and the guide light source, in which the controller causes the image processor to generate an illumination light image based on an optical image acquired during a period in which the illumination light source and the guide light source are ON and to generate a fluorescence image based on a fluorescence image acquired during a period in which the therapeutic light source is ON and the illumination light source and the guide light source are OFF.

Abstract: Provided is a spectroscopic analysis apparatus including: an optical probe; and a spectroscopic analysis portion to which the optical probe is attached. The optical probe includes an optical fiber that guides illumination light coming from a light source and signal light coming from an observation target and an optical member that is disposed at least at a distal end of the optical fiber. The spectroscopic analysis portion includes an information separation portion that generates wavelength dependent characteristics by optically dispersing the signal light and that separates, from information about the signal light, information about first return light returning from the optical member and information about second return light returning from the optical fiber, a problem determining portion that determines a problem occurring at the optical probe based on the separated first return light and second return light, and a notification portion that notifies information about the determined problem.

Abstract: An image signal processing device includes: a processor configured to process a first image signal and a second image signal, the first image signal being obtained by a first imaging portion capturing excitation light that is reflected from an observation target by irradiating the observation target with the excitation light, the second image signal being obtained by a second imaging portion capturing fluorescence from the observation target when excited by irradiating the observation target with the excitation light.
