1. An image display device comprising:
a display configured to display a pointer corresponding to a remote controller;
an external device interface including at least one communication module and configured to perform short-range communication; and
a controller,
wherein the controller:
receives, from the remote controller, an input signal including movement data of the remote controller through the external device interface;
monitors a connection status with the remote controller based on the received input signal;
if the connection status is good, calculates coordinates of the pointer based on the movement data included in the input signal;
if the connection status is bad, processes the movement data included in the input signal, and then calculates coordinates of the pointer based on the processed data; and
displays the pointer on the display based on the calculated coordinates of the pointer.
