Abstract:
A biometric image pickup apparatus with a simple configuration capable of reducing light amount variations in a picked-up image. The biometric image pickup apparatus includes: a light source applying light to a living organism; a detection section for placing the living organism thereon; an image pickup lens section condensing light from the living organism; an image pickup device obtaining image pickup data on the basis of the light condensed by the image pickup lens section; and a transmittance distribution filter arranged between the detection section and the image pickup device, in which the transmittance distribution filter has a transmittance distribution in which the transmittance is higher in a region far from the light source than in a region near the light source.
