Abstract
A power supply control device includes a power supply controller that selectively performs a power supply mode and a power saving mode, a detector that detects a moving body in a predetermined range in the vicinity of the processor, a power supply mode change instruction unit that changes an operation mode from the power saving mode to the power supply mode when the detector detects the moving body, an information history unit that acquires information related to an operation for the processor in the power supply mode, and a sensitivity adjusting unit that adjusts a detection sensitivity of the detector for the moving body on the basis of the information acquired by the information history unit for a period from a change of the operation mode from the power saving mode to the power supply mode to a change of the operation mode to a next power saving mode.
