Abstract
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.
Claims20
A biometric-information processing device comprising:
- an image acquisition unit configured to acquire an image of a biometric object using light reflected from the biometric object;
- and
- 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.
A method of processing biometric information comprising:
- acquiring an image of a biometric object using light reflected at the biometric object;
- and
- extracting, by a processor, a frequency component having a frequency higher than a predetermined spatial frequency from the image acquired in the acquiring.
A computer-readable storage medium storing a biometric-information processing program that causes a computer to execute a process comprising:
- acquiring an image of a biometric object using light reflected from the biometric object;
- and
- extracting frequency component having a frequency higher than a predetermined spatial frequency from the image acquired by the image acquisition unit.
