In Fig. 6, a plurality of images or a plurality of objects having different depths are shown. These objects are referred to as a first object 615, a second object 625, a third object 635, and a fourth object 645.

That is, the first object 615 is composed of a first left eye image based on the first left eye image signal and a first right eye image based on the first right eye image signal. That is, the video signal for displaying the first object is composed of the first left eye image signal and the first right eye image signal. 6 shows the positions of the first right eye image based on the first left eye image signal and the first right eye image signal on the display unit 180 based on the first left eye image signal. 6 shows an interval between the first left-eye image and the first right-eye image displayed on the display unit 180. FIG. The description of the first object may be applied to the second to fourth objects. Hereinafter, for convenience of explanation, the left eye image and the right eye image displayed on the display unit 180 for one object, and the interval set between the two images and the serial numbers of the objects will be described in unison.

The first object 615 is composed of a first right eye image 613 (indicated by R1 in Fig. 6) and a first left eye image 611 (indicated by L1 in Fig. 6). The interval between the first right eye image 613 and the first left eye image 611 is set to d1. The user recognizes the elongation that connects the left eye 601 and the first left eye image 611 and that the image is formed at a point where an extension line connecting the right eye 603 and the first right eye image 603 intersects. Accordingly, the user recognizes that the first object 615 is located behind the display unit 180. [ The distance between the display unit 180 and the first object 615 recognized by the user can be represented by a depth. In this embodiment, the 3D object recognized by the user has a negative value (-) as if it is positioned behind the display unit 180.

In addition, the image display apparatus 100 can control the depth sense of the object composed of the left eye image and the right eye image by adjusting the display intervals of the left eye image and the right eye image displayed on the display unit 180. [

That is, according to the description with reference to FIG. 6, whether the depth of an object composed of a left eye image and a right eye image has a positive value (+) or a negative value (-) according to the left and right display positions of the left eye image and the right eye image Is determined. As described above, an object having a positive value (+) in depth is an object recognized by the user as if it is located protruding from the display unit 180. Also, an object whose depth has a negative value (-) is an object recognized by the user as if it is positioned behind the display unit 180.

Referring to FIG. 6, the depth of the object, that is, the distance between the point at which the 3D image is recognized by the user and the display unit 180 varies according to the absolute value of the interval between the left eye image and the right eye image can do.

7,

In this embodiment, the depth of the display unit 180 is set to zero. The depth of the image recognized as being projected from the display unit 180 is set to have a positive value.

An interval between the left eye image 701 and the right eye image 702 shown in FIG. 7A is a. The interval between the left eye image 701 and the right eye image 702 shown in FIG. 7 (b) is b. Where b is greater than aa. That is, the interval between the left eye image 701 and the right eye image 702 in the example shown in FIG. 7 (b) is wider than the example shown in FIG. 7 (a).

In this case, as described with reference to Fig. 6, the depth feeling of the 3D image or the 3D object shown in Fig. 7B is larger than the depth feeling of the 3D image or 3D object shown in Fig. 7A . In each case, when the depth sense is expressed numerically and denoted by a 'and b', respectively, it can be understood that the relationship of a '<b' is also established according to the relation of a <b. That is, when it is desired to implement a 3D image which is seen as a protruding, the depth feeling expressed by the widening or narrowing of the interval between the left eye image 701 and the right eye image 702 may become larger or smaller.
