Abstract: An electronic device is provided. The electronic device includes a camera including a lens unit and a lens driving unit and a processor configured to obtain a first image of an object from the camera, move the lens unit by a specified amount using the lens driving unit, obtain a second image of the object that corresponds to a position to which the lens unit is moved, determine a focus position for an image of the object based on a difference between the first image, the second image, and the specified amount of movement, determine an amount of movement for moving the lens unit to the focus position including determining a distance between the object and the lens unit and correcting the determined amount of movement based on the determined distance, and move the lens unit by the determined amount of movement using the lens driving unit.

Abstract: An electronic device includes a camera and a processor. The processor is configured to: obtain a first image from the camera with respect to an external object, move a lens device depending on a specified amount of movement using a lens driver, obtain a second image corresponding to a position to which the lens device moves with respect to the external object, determine a first partial area of the first image corresponding to a specified portion of the external object, determine a second partial area of the second image corresponding to the first partial area based on the first partial area and the specified movement amount, determine a focus position with respect to the lens device based on a defocus difference between the first partial area and the second partial area and the specified movement amount, and move the lens device to the focus position using the lens driver.
