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.
