<p>To adequately acquire biometric information even when a feature amount of the biometric information may vary by a variety of factors. A biometric information acquisition apparatus (1) acquires biometric information to be used for verification. The biometric information acquisition apparatus (1) includes a blood flow increasing unit (2a), a biometric information acquiring unit (2b), a feature amount evaluating unit (2c), and a reacquisition determining unit (2d). The blood flow increasing unit (2a) increases blood flow of an object person. The biometric information acquiring unit (2b) acquires the biometric information from the object person. The feature amount evaluating unit (2c) evaluates the feature amount of the acquired biometric information. The reacquisition determining unit (2d) determines whether to cause the blood flow increasing unit (2a) to operate and then cause the biometric information acquiring unit (2b) to reacquire the biometric information when the evaluated feature amount does not reach a predetermined threshold.</p> |
