BIOMETRIC-INFORMATION PROCESSING DEVICE, METHOD OF PROCESSING BIOMETRIC INFORMATION, AND COMPUTER-READABLE RECORDING MEDIUM STORING BIOMETRIC-INFORMATION PROCESSING PROGRAM

摘要

A biometric-information processing device includes an image acquisition unit configured to acquire an image of a biometric object using light reflected from the biometric object. The biometric-information processing device further includes an extracting unit configured to extract a frequency component having a frequency higher than a predetermined spatial frequency at the image acquired by the image acquisition unit.
