INFORMATION PROCESSOR, PROGRAM AND METHOD

摘要

PROBLEM TO BE SOLVED: To improve estimation accuracy of a finger movement direction in a case in which the finger movement direction is estimated when a fingerprint is imaged by a fingerprint sensor on the basis of the fingerprint image imaged by the fingerprint sensor.SOLUTION: An information processor comprises: a fingerprint sensor for acquiring a fingerprint image by imaging a fingerprint; a first estimation part for estimating a finger movement direction when the fingerprint image is imaged on the basis of the fingerprint image imaged by the fingerprint sensor while the finger is moved on the fingerprint sensor; a rotation motion sensor for detecting a rotation motion accompanied by the finger movement on the fingerprint sensor; a second estimation part for estimating the finger movement direction when the fingerprint image is imaged on the basis of the rotation motion detected by the rotation motion sensor when the fingerprint image is imaged; a determination part for determining whether or not the finger movement direction estimated by the first estimation part coincides with the finger movement direction estimated by the second estimation part; and an execution part for executing a function corresponding to the finger movement direction when the determination part determines that they coincide with each other.
