Abstract
A portable electronic apparatus includes an acceleration detection unit, an evaluation-signal generation unit, and a control unit. The acceleration detection unit is configured to detect an acceleration generated in the portable electronic apparatus. The evaluation-signal generation unit is configured to carry out a predetermined process based on the acceleration detected by the acceleration detection unit in order to generate an evaluation signal representing the amplitude and positive or negative polarity of the acceleration. The control unit is configured to produce a result of determination as to whether or not the portable electronic apparatus has been driven to make a predetermined movement on the basis of the evaluation signal and carrying out a predetermined operation on the basis of the result of determination.
