Electronic apparatus and control method therefor

摘要

An electronic apparatus and a control method are provided that are capable of reducing power consumption. The electronic apparatus having a normal mode in which first electric power is consumed and a power-saving mode in which second electric power lower than the first electric power is consumed includes a first sensor and a second sensor whose power consumption is lower than that of the first sensor. In the power-saving mode, supply of power to the first sensor is restricted, the second sensor is set to the power-saving mode, a trigger for restoring the power-saving mode to the normal mode is detected by using the second sensor set to the power-saving mode, and the power-saving mode is restored to the normal mode based on the detected trigger.

主权项

1. An electronic apparatus comprising:
a first sensor with a first normal power mode and a first power-saving mode; a second sensor with a second normal power mode and a second power-saving mode; and a control unit configured to receive acceleration values from the first sensor and the second sensor and determine modes for each of the first sensor and the second sensor based on said acceleration values, wherein the control unit is further configured to: change the second sensor to the second power-saving mode and the first sensor into the first power saving mode when first acceleration values of the first sensor are smaller than a first predetermined value over a period of time; detect a trigger for causing the second sensor to be restored to the second normal power mode; and cause the second sensor to be restored to the second normal power mode.
