Provided is an image capturing apparatus for generating a multi-band image for examining a disease condition which has little amount of information. The image capturing apparatus includes: a variable spectroscopic element capable of varying a wavelength of light to be transmitted; a wavelength band table recording therein wavelength bands corresponded with disease conditions; an observation target identifying section that identifies a disease condition to be observed; a variable spectroscopic element control section that controls the variable spectroscopic element to sequentially transmit light rays of a plurality of wavelengths within a range of a wavelength band recorded in the wavelength band table in correspondence with the disease condition identified by the observation target identifying section; and an image capturing section that sequentially captures images by means of the light rays of a plurality of wavelengths transmitted through the variable spectroscopic element.
