Abstract: The present disclosure relates to an image display device and a method of operating the same. The image display device according to an embodiment of the present disclosure includes: 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. Various other embodiments are also possible.
