1. An image processing method of processing image data generated by an image sensor, the image sensor including a pixel array, the image processing method comprising:
calculating position information according to pixel positions in the image data, the pixel positions corresponding to pixels of the pixel array; and
correcting a phase difference of the image data based on the position information,
wherein the calculating the position information includes calculating a magnitude of a radial field from a center of the pixel array to a target pixel of the pixel array, and
wherein the correcting the phase difference of the image data includes adjusting a phase difference correction strength based on the magnitude of the radial field according to a setting value and characteristic information associated with the image sensor.
