摘要： An endoscope apparatus (10) includes an imager (22) that detects reflected and scattered light of illumination light radiated to an observation object to output an imaging signal, and an image processor (24) that generates an image signal from the imaging signal. The image processor (24) generates an emphasis image signal corresponding to narrow band light included in an emphasis wavelength range that includes, for an optical absorption spectrum of a diagnosis target substance present in the observation object (O), at least one of at least a maximum wavelength that takes at least a maximum value and a color-range largest wavelength that takes a color-range largest value that is a largest value of the optical absorption spectrum in any one color range of three color ranges, a first color range, a second color range, and a third color range, and a non-emphasis image signal corresponding to narrow band light included in a non-emphasis wavelength range that is a wavelength range that does not include the emphasis wavelength range.

摘要： A light source device (2) includes excitation light sources (4, 5), wavelength converting members (12), an input unit (6) and a light source control unit (7). The excitation light sources (4, 5) emit a plurality of excitation light including mutually different spectra. The wavelength converting members (12) are disposed in a common application region of the plurality of excitation light and wavelength-convert the plurality of excitation light emitted from the excitation light sources (4, 5) into light having mutually different spectra. The light source control unit (7) is able to switch a combination of the excitation light sources that are lighted among the excitation light sources (4, 5) based on an observation mode including a normal light observation mode and a special light observation mode to highlight a particular observation target input to thee input unit (6). The light source device (2) uses light emitted from the wavelength converting members as illumination light, and emits the illumination light corresponding to the observation modes from a same emitting portion.
