In addition, as shown in FIG. 7D, at least a part of the 3D object may be rotated (parallel quadrilateral shape) 518. This scaling (scaling) or skew adjustment can emphasize the 3D effect of a 3D object in a 3D image or a 3D image, that is, a 3D effect.
On the other hand, as the slope becomes larger, as shown in FIG. 7 (b) or 7 (c), the length difference between the parallel sides of the trapezoidal shapes 514 and 516 increases, or as shown in FIG. It gets bigger.

[ At this time, the user recognizes that an image is formed at an intersection of an extension line connecting the left eye 601 and the first left eye image 611 and an extension line connecting the right eye 603 and the first right eye image 603. Accordingly, the user recognizes that the first object 615 is positioned behind the display 180. [
Next, since the second object 625 includes the second left eye image 621, L and the second right eye image 623, R and overlaps with each other and is displayed on the display 180, do. Accordingly, the user recognizes that the second object 625 is located on the display 180. [
Next, the third object 635 and the fourth object 645 are arranged in the order of the third left eye image 631, L, the second right eye image 633, R, the fourth left eye image 641, Right eye image 643 (R), and their intervals are d3 and d4, respectively.
According to the above-described method, the user recognizes that the third object 635 and the fourth object 645 are positioned at positions where the images are formed, respectively, and recognizes that they are located before the display 180 in the drawing.
At this time, it is recognized that the fourth object 645 is projected before the third object 635, that is, more protruded than the third object 635. This is because the interval between the fourth left eye image 641, L and the fourth right eye image 643, d4 is larger than the interval d3 between the third left eye image 631, L and the third right eye image 633, R. [
Meanwhile, in the embodiment of the present invention, the distance between the display 180 and the objects 615, 625, 635, and 645 recognized by the user is represented by a depth. Accordingly, it is assumed that the depth when the user is recognized as being positioned behind the display 180 has a negative value (-), and the depth when the user is recognized as being positioned before the display 180 (depth) has a negative value (+). That is, the greater the degree of protrusion in the user direction, the greater the depth.
9, the distance a between the left eye image 701 and the right eye image 702 of FIG. 9A is a distance between the left eye image 701 and the right eye image 702 shown in FIG. 9B. When (b) is smaller, it can be seen that the depth a 'of the 3D object of FIG. 9 (a) is smaller than the depth b' of the 3D object of FIG. 9 (b).
In this way, when the 3D image is exemplified as the left eye image and the right eye image, the positions recognized as images are different depending on the interval between the left eye image and the right eye image. Accordingly, by adjusting the display intervals of the left eye image and the right eye image, the depth of the 3D image or the 3D object composed of the left eye image and the right eye image can be adjusted.
FIG. 10 is a diagram illustrating a control method of the remote controller of FIG. 2.

FIG. 10C illustrates a case in which the user moves the remote control apparatus 200 away from the display 180 while pressing a specific button in the remote control apparatus 200. 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 device 200 moves away from or near the display 180, the up, down, left and right movements are not recognized, and only the front and back movements can be 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.

The controller 170 of the image display apparatus 100 determines whether the received image is a 2D image or a 3D image. For example, when the header, flag, or the like of the received video signal is examined to indicate that the video type information is a 3D video type, it may be determined as a 3D video.
Alternatively, when the received image is a multi-view image including a left eye image and a right eye image, the controller 170 of the image display apparatus 100 may determine the 3D image.
The controller 170 of the image display apparatus 100 processes the received 3D image by 3D signal. For example, the controller 170 may separate the received 3D image into a left eye image and a right eye image, arrange the left eye image and the right eye image according to the predetermined format of FIG. 5, and output the same to the display 180. .
In particular, the formatter 360 in the controller 170 may be divided into a left eye image and a right eye image, and the left eye image and the right eye image may be arranged according to the predetermined format of FIG. 5, and the formatter 360 may include a controller ( It is also possible to be disposed separately without being provided in 170.
The display 180 may display a left eye image and a right eye image at different times or in different regions. Accordingly, the user can view the 3D image including the left eye image and the right eye image through the active or passive 3D viewing device 195.
Next, the image display apparatus 100 displays a guide object for setting a 3D display mode in response to the 3D image (S1225). Then, it is determined whether the 3D display mode setting is completed using the guide object (S1230), and if applicable, an object indicating the 3D display mode set according to the guide object is displayed (S1235). In operation S1240, the 3D image is displayed according to the set 3D display mode.
