2. The portable electronics according to claim 1, further comprising:

an input unit which receives a request from a user; and

a request detection unit which detects input of the request to the input unit,

wherein when the request detection unit has detected the input of the request, the determination unit reads out, every time the second period has elapsed, the plurality of detection results stored in the storage unit during the second period and determines the state of the portable electronics based on the plurality of readout detection results.

3. The portable electronics according to claim 2, wherein the determination unit determines the state of the portable electronics based on detection results which are stored in the storage unit until the request detection unit has detected the input of the request.

4. The portable electronics according to claim 2, wherein the determination unit determines the state of the portable electronics based on detection results which are stored in the storage unit after the request detection unit has detected the input of the request.

5. The portable electronics according to claim 2, further comprising an ambient state detection unit which detects a state around the portable electronics,

wherein the storage unit stores, at the first period, a plurality of detection results except detection results detected by the detection unit during detection of a preset state by the ambient state detection unit.

6. The portable electronics according to claim 1, wherein the detection unit detects an acceleration generated in the portable electronics.

7. The portable electronics according to claim 1, further comprising a switching unit which switches an operating state of a control unit controlling the portable electronics from a sleep state to an active state or from the active state to the sleep state in accordance with a determination result of the determination unit.

8. The portable electronics according to claim 1, further comprising a switching unit which switches an operating state of the portable electronics from a high power consumption state to a low power consumption state or from the low power consumption state to the high power consumption state in accordance with a determination result of the determination unit.

9. The portable electronics according to claim 1, further comprising a switching unit which switches several functions of the portable electronics from an operating state to a stop state or from the stop state to the operating state in accordance with a determination result of the determination unit.

10. A sensing method comprising:
