    Abstract: 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.

    Abstract: To accurately detect the presence or absence of a signal. A signal detector includes an input-signal amplifying circuit, a reference-signal amplifying circuit, and a comparator. In the signal detector, the input-signal amplifying circuit amplifies an input signal with a predetermined gain. The reference-signal amplifying circuit amplifies a reference signal at a constant signal-level with a gain that substantially matches the predetermined gain. The comparator compares a signal level of the amplified input signal with a signal level of the amplified reference signal, and outputs the comparison result as a detection signal.
