5 is a flowchart illustrating a method of operating an image display apparatus according to an exemplary embodiment. FIG. 6 is a diagram referred to describe the operation method of FIG. 5.

First, a pointer corresponding to the spatial remote control operation is displayed on the display (S510).

Then, in a state where a pointer is displayed, such as when a command for displaying an object is received from the user, or when an object displaying state information of the image display device is displayed, or when an object confirming the user's command is displayed. When the object is displayed, the controller 170 displays the object on the display to overlap the pointer. (S520) The object display step S520 will be described in detail with reference to the exemplary embodiments of FIG.

As shown in FIG. 6A, the object 600 and the pointer 650 are overlapped with each other, so that the user can minimize an operation of moving the pointer 650 to select, execute and terminate the object.

In addition, when the pointer 650 is located at the edge of the display screen, the object may be displayed by moving the display screen to determine whether the distance between the end of the display screen and the pointer 650 is sufficient to display the object. .

If the pointer is located at a position where there is no problem in displaying the object, it is more preferable that the pointer 650 is displayed at the center of the object 600 as shown in FIG.

First, as shown in FIG. 8A, a pointer 850 corresponding to a spatial remote controller operation is displayed on a display (S710).

Subsequently, when the object 800 is displayed on the display while the pointer 850 is displayed on the display as shown in FIG. 8B, the controller (S720) controls the object (FIG. 8C). The pointer 850 is moved and displayed to overlap with 800. (S730)

Also in this embodiment, as described above, the pointer can be displayed by moving the pointer to the center of the object or an area in which a command can be input among the objects. Accordingly, it is possible to minimize the user's pointer movement.

As such, by automatically moving the pointer, the user can easily select one of the items in the object or input a command. Therefore, user convenience is increased.

In addition, when a plurality of objects are displayed, the pointer may be displayed to overlap with the latest displayed object, or the pointer may be displayed by moving the pointer, and may be applied to the object having the highest priority according to the priority of the preset object.

In the drawings, an arrow is illustrated as an example of a pointer, but is not limited thereto, and may be represented by a cursor, an image, an icon, or the like.

According to the present invention, the object is displayed in the area where the pointer is located, or the pointer is positioned in the object by moving the pointer to the area where the object is displayed. Accordingly, the user can select or execute an object that wants a pointer more quickly and easily, thereby reducing the user's operation time and the number of operations and increasing user convenience.

Meanwhile, the present invention can be embodied as processor readable codes on a processor readable recording medium included in the image display device. The processor-readable recording medium includes all kinds of recording devices that store data that can be read by the processor. Examples of the processor-readable recording medium include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage device, and the like, and also include a carrier wave such as transmission through the Internet. The processor-readable recording medium can also be distributed over network coupled computer systems so that the processor-readable code is stored and executed in a distributed fashion.

In addition, although the preferred embodiment of the present invention has been shown and described above, the present invention is not limited to the specific embodiments described above, but the technical field to which the invention belongs without departing from the spirit of the invention claimed in the claims. Of course, various modifications can be made by those skilled in the art, and these modifications should not be individually understood from the technical spirit or the prospect of the present invention.
