The image display apparatus can calculate the coordinates of the pointer 205 from the information on the motion of the remote control apparatus 200. [ The image display apparatus can display the pointer 205 so as to correspond to the calculated coordinates.

3C illustrates a case where the user moves the remote control device 200 away from the display 180 while the specific button in the remote control device 200 is depressed. Thereby, the selected area in the display 180 corresponding to the pointer 205 can be zoomed in and displayed. Conversely, when the user moves the remote control device 200 close to the display 180, the selection area within the display 180 corresponding to the pointer 205 may be zoomed out and zoomed out. On the other hand, when the remote control device 200 moves away from the display 180, the selection area is zoomed out, and when the remote control device 200 approaches the display 180, the selection area may be zoomed in.

On the other hand, when the specific button in the remote control device 200 is pressed, it is possible to exclude recognizing the up, down, left, and right movement. That is, when the remote control apparatus 200 moves away from or approaches the display 180, it is not recognized that the up, down, left, and right movements are recognized, and only the forward and backward movements are recognized. Only the pointer 205 is moved in accordance with the upward, downward, leftward, and rightward movement of the remote control device 200 in a state where the specific button in the remote control device 200 is not pressed.

On the other hand, the moving speed and moving direction of the pointer 205 may correspond to the moving speed and moving direction of the remote control device 200.

That is, when the OK key 291 is pressed, it is used as a menu or item selection. When the OK key 291 is scrolled up and down, a display screen scrolling or a list page switching can be performed.

Specifically, when an image larger than the size of the display 180 is displayed on the display 180, when the OK key 291 is scrolled to search for the image, an image area that is not currently displayed on the display is displayed on the display do. As another example, when the list page is displayed on the display unit 180, the previous page or the next page of the current page can be displayed by scrolling the OK key 291. [

This scroll function may be provided with a separate key other than the confirmation key 291. [

On the other hand, the four directional keys 293 can be arranged in four directions in the circular type, as shown in the figure, up, down, left, and right keys.
