    Abstract: A method for correcting coordinates of an electronic pen having a pen contact and a coil which are spaced apart by a predetermined distance and an electronic pen by using a portable electronic device is provided. The method includes calculating a coordinate correction angle, calculating a coordinate correction distance from an electromagnetic induction point on a display unit of the portable electronic device, on which an electromagnetic field generated by electromagnetic induction between the coil and a sensor board of the portable electronic device is measured, to a contact point of the pen contact with respect to the display unit, and determining a coordinate of the electronic based on the calculated coordinate correction angle and the calculated correction distance.
