Abstract
An electronic apparatus that can receive power from an external apparatus connected via an interface and comprises an interface having a first terminal and a second terminal. The apparatus determines whether or not a time difference between a time of detection of a first voltage at a first terminal and a time of detection of a second voltage at a second terminal is smaller than or equal to a predetermined value, determines a type of the external apparatus by executing first connected device detection if the time difference is smaller than or equal to the predetermined value, and executing second connected device detection different from the first connected device detection if the time difference is larger than the predetermined value, and performs power reception control based on a result of determination of a type of the external apparatus.
