Abstract: An endoscope apparatus configured to acquire an image of an observation object includes a light source unit and an imaging system. The light source unit includes a first light source configured to emit first narrow band light selected based on an absorption spectrum of a first characteristic substance, and a second light source configured to emit second narrow band light selected based on an absorption spectrum of a second characteristic substance. The imaging system includes an image sensor configured to separately acquire a first image by the first narrow band light and a second image by the second narrow band light.

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.

Abstract: A light source system includes an illumination device configured to generate illumination light, and a light source module having a function of supplying light to the illumination device and configured to be detachably attached to the illumination device. The illumination device includes a first light source and a first storage configured to store characteristic information of the first light source. The light source module includes a second light source and a second storage configured to store characteristic information of the second light source. The illumination device includes a control circuit configured to determine a driving condition of at least one of the first and second light sources, based on the characteristic information of the first and second light sources.

Abstract: An endoscope includes an illuminator to emit illumination light comprised by narrow band lights different in wavelength from an end portion of the endoscope and an imager to image an observation object illuminated by the illumination light emitted from the illuminator. The illuminator includes a light quantity output adjuster to independently control the light quantity of each of the narrow band lights. The endoscope allows observation in three types of modes of a white light mode, a special light mode, and a hybrid mode. A spectral pattern of illumination light in the hybrid mode includes at least a part of a color region of a narrow band light included in the special light mode and is different from either of a spectral pattern of illumination light in the white light mode and a spectral pattern of illumination light in the special light mode.
