Abstract
A wireless power receiving device that receives AC power from a power transmission coil included in a wireless power transmission device. The wireless power receiving device includes a power receiving coil configured to receive AC power from a power transmission coil, a power receiving-side imaging unit having an auto-focus function, and a control unit configured to cause the power receiving-side imaging unit to image a range able to be imaged by the power receiving-side imaging unit and, in a case in which a marker located at a predetermined first position on an outer surface of the wireless power transmission device is imaged by the power receiving-side imaging unit, to output relative distance information representing relative distance of the power receiving coil with respect to the power transmission coil based on a detected distance using the auto-focus function used by the power receiving-side imaging unit for imaging the marker.
