Referring to FIG. 6A, a first image 610 is displayed on a display of an image display device. Receiving a video change command in real time from a user, or when a video change command reserved at a predetermined time point is received, a second image 632 is acquired, and at least one of the first image 631 being viewed as shown in FIG. A part is displayed in at least one area of the 3D object. In addition, at least one portion of the second image 632 may be displayed on at least one region of the 3D object.

The method may further include reducing the screen of the first image to a size of one region of the 3D object when the image change command is received.

Thereafter, as shown in FIG. 6C of the 3D object, one surface of the 3D object on which the first image 631 is displayed rotates similarly to turning over a bookshelf, and the display state is changed. As turning the bookshelf, the area in which the first image is displayed gradually decreases, and the area in which the second image is displayed gradually increases, and when the bookcase is completely over, that is, when the rotation of the first image is completed, FIG. 6 (d). As described above, only the area where the second image is displayed is displayed on the screen.

After the display state of the 3D object is changed, only the second image 640 is displayed on the entire screen.

In addition, the second image displayed on one region of the 3D object may be displayed as a still image state for a predetermined time and then converted into a moving image.

In the case of a still image, the acquisition and display can be performed at a higher speed than the moving image, and thus, the still image is displayed first and the moving image can be reduced to reduce boredom and bodily time in the process of changing an image.

FIG. 7 illustrates an embodiment in which the display state change of the 3D object corresponds to the operation of the spatial remote controller.

Can be displayed on the display. The game input signal may be a window for selecting games pre-stored in the image display device or a signal input from an external game device.

The image change command may be a switch command between an analog broadcast signal and a digital broadcast signal, or an object state change command such as osd. In general osd, when the upper menu is selected, the user directly switches to the lower menu, so it is not easy for the user to intuitively recognize the relationship between the information and the flow of information. Therefore, the user can visually recognize the object switching process as an animation effect of the three-dimensional object.
