A biometric information process device comprising: a biometric information storage configured to store enrolled biometric information; a distance information storage configured to store a first ratio related with the enrolled biometric information; a detector configured to detect a touch point of a finger with respect to a touch panel; an image device configured to capture an image of a palm; an extractor configured to extract a biometric feature from the image of the palm that is acquired by the image device; a corrector configured to correct the enrolled biometric information or biometric information extracted by the extractor by enlarging or downsizing based on the first ratio and a second ratio; and a comparer configured to compare the enrolled biometric information with the biometric information extracted by the extractor after correcting by the corrector, wherein: the enrolled biometric information is acquired from the image of the palm in a case where a region of the finger contacting to the touch panel moves in advance; the first ratio is a ratio between a movement amount of the finger on the touch panel and a movement amount of the biometric feature in the image of the palm when the biometric information storage stores the enrolled biometric information; and the second ratio is a ratio between the movement amount of the finger on the touch panel and the movement amount of the biometric feature in the image of the palm when the comparer compares the enrolled biometric information with the biometric information extracted by the extractor after correcting by the corrector. a biometric information storage configured to store enrolled biometric information; a distance information storage configured to store a first ratio related with the enrolled biometric information; a detector configured to detect a touch point of a finger with respect to a touch panel; an image device configured to capture an image of a palm; an extractor configured to extract a biometric feature from the image of the palm that is acquired by the image device; a corrector configured to correct the enrolled biometric information or biometric information extracted by the extractor by enlarging or downsizing based on the first ratio and a second ratio; and a comparer configured to compare the enrolled biometric information with the biometric information extracted by the extractor after correcting by the corrector, wherein: the enrolled biometric information is acquired from the image of the palm in a case where a region of the finger contacting to the touch panel moves in advance; the first ratio is a ratio between a movement amount of the finger on the touch panel and a movement amount of the biometric feature in the image of the palm when the biometric information storage stores the enrolled biometric information; and the second ratio is a ratio between the movement amount of the finger on the touch panel and the movement amount of the biometric feature in the image of the palm when the comparer compares the enrolled biometric information with the biometric information extracted by the extractor after correcting by the corrector. the enrolled biometric information is acquired from the image of the palm in a case where a region of the finger contacting to the touch panel moves in advance; the first ratio is a ratio between a movement amount of the finger on the touch panel and a movement amount of the biometric feature in the image of the palm when the biometric information storage stores the enrolled biometric information; and the second ratio is a ratio between the movement amount of the finger on the touch panel and the movement amount of the biometric feature in the image of the palm when the comparer compares the enrolled biometric information with the biometric information extracted by the extractor after correcting by the corrector. <EOS>
