Zusammenfassung:A biometric capture device includes: a first light source configured to emit a light of a first wavelength to a biometric body; a second light source configured to emit a light of a second wavelength different from the first wavelength to the biometric body; a camera configured to capture a reflected light from the biometric body; a biometric information acquirer configured to acquire a biometric image based on a component of the first wavelength from an image captured by the camera; a distance information acquirer configured to acquire distance information between the biometric body and the camera based on a component of the second wavelength from the image captured by the camera; and a corrector configured to correct the biometric image based on the distance information.
