Abstract: A method for sensing proximity by an electronic device is provided. The method includes confirming a phase difference regarding a corresponding subject of an image acquired through a lens of the electronic device by operating a phase-difference autofocus sensor and determining that the corresponding subject is proximate to the electronic device when the confirmed phase difference is larger than a designated first reference value.
