8 (b), when the object 800 is displayed on the display in the state that the pointer 850 is displayed on the display, the control unit displays the object 800 (FIG. 8 The pointer 850 is moved so as to overlap with the display screen 800 (S730)

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

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

Also, when a plurality of objects are displayed, the pointer can be displayed so as to overlap with the latest displayed object, or the pointer can be moved and displayed, and it can be applied to the object having the highest priority according to the priority of the predetermined object.

In the drawing, an arrow is shown as an example of a pointer, but the present invention is not limited to this, and may be displayed as a cursor, an image, an icon, or the like.

According to the present invention, an object is displayed in an area where a pointer is located, or a pointer is moved and displayed in an area where an object is displayed, so that a pointer is placed in the object. Accordingly, the user can select or execute the object desired by the pointer more quickly and easily, so that the user's operation time and the number of operation times are reduced and the user convenience is increased.

Meanwhile, the present invention can be embodied as a code readable by a processor in a processor-readable recording medium provided in an image display apparatus. The processor-readable recording medium includes all kinds of recording apparatuses in which data that can be read by the processor is stored. Examples of the recording medium readable by the processor include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like, and also a carrier wave such as transmission over the Internet. In addition, the processor readable recording medium may be distributed over networked computer systems so that code readable by the processor in a distributed manner can be stored and executed.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention.
