1. A biometric image pickup apparatus comprising:

  • a light source section selectively switching between light of a first wavelength region with a high transmittance through a living organism and light of a second wavelength region with a lower transmittance through the living organism than light of the first wavelength region to apply the light of the first wavelength region and the light of the second wavelength region to the living organism;

    an image pickup lens section condensing light from the living organism;

    an image pickup device obtaining first image pickup data of the living organism on the basis of the light of the first wavelength region in light condensed by the image pickup lens, and obtaining second image pickup data on the basis of the light of the second wavelength region in the light condensed by the image pickup lens; and

    an image processing section obtaining difference image data between the first image pickup data and the second image pickup data obtained by the image pickup device.
