Abstract:
1. An image pickup apparatus, comprising: an irradiation unit configured to radiate light having a plurality of wavelength regions to an object; an image pickup unit configured, for each wavelength region of the plurality of wavelength regions, to pick up a first image of the object at a particular wavelength region of the plurality of wavelength regions, the first image obtained in a presence of the radiated light and a second image of the object at the particular wavelength region of the plurality of wavelength regions, the second image obtained in an absence of the radiated light; a wavelength region calculating unit configured to determine a wavelength region among the plurality of wavelength regions in which intensity of external light is low based on intensity values corresponding to the first image and the second image at each wavelength region; and an irradiation control unit configured to control the radiated light from the irradiation unit to increase an emission intensity of light having the wavelength region determined by the wavelength region calculating unit.
