1. An electronic device, comprising:
a camera;
an image sensor including a plurality of image pixels arranged in a first direction and a second direction orthogonal to the first direction, and configured to convert light incident on a plurality of micro-lenses into an electrical signal, perform a first correlation calculation for phase difference detection in the first direction based on the electrical signal, and output image data including phase difference information and a first phase difference correlation calculation value;
an image signal processor (ISP) configured to perform a second correlation calculation for phase difference detection in the second direction using the phase difference information of the image data outputted from the image sensor; and
a driver configured to adjust a focus of the camera based on the first phase difference correlation calculation value for the first direction and a second phase difference correlation calculation value for the second direction.
