PROBLEM TO BE SOLVED: To reduce power consumption in a power saving mode when an electronic device has a plurality of power modes different in power consumption as the power saving mode.SOLUTION: A power control section 509 selectively executes first power control as power control of a power saving mode, and second power control smaller in power consumption than the first power control. A mode setting section 507 selectively sets a setting to a low power mode and a sleep mode as the power saving mode, and after the setting is set to the low power mode, when a return instruction is not received by a return reception section 505 and a predetermined period of time elapses, changes over the setting to the sleep mode from the low power mode. When the low power mode is set by the mode setting section 507, the power control section 509 alternately repeats a period of time of the first power control and a period of time of the second power control, and when the sleep mode is set by the mode setting section 507, performs the second power control. |
