The first category is a method in which the same image is provided in both eyes (monoscopic), which can be implemented as a general display unit. More specifically, the controller 180 arranges a polyhedron generated through one or more points, lines, planes, or a combination thereof in a virtual three-dimensional space, and displays an image viewed from a specific viewpoint on the display unit 151. That's how. Therefore, the substantial part of such a stereoscopic image can be referred to as a planar image.

The second category is a stereo scopic method in which different images are provided in both eyes. It is a method using a principle of feeling a three-dimensional feeling when a human is looking at an object with the naked eye. In other words, the two eyes of a person see different plane images when they see the same thing by the distance between them. These different planar images are transmitted to the brain through the retina, and the brain fuses them to feel the depth and reality of the stereoscopic image. Therefore, binocular disparity due to the distance between the two eyes makes a sense of stereoscopic effect, and this binocular disparity becomes the most important element of the second category. This binocular disparity will be described in more detail with reference to Fig.

3 is a conceptual diagram for explaining the principle of binocular disparity.

In FIG. 3, it is assumed that the cube 31 is viewed with the naked eye in front of the eye level. In this case, the left eye planar image 32 is seen in which only three surfaces of the top, front, and left sides of the hexahedron 31 are visible. In addition, as the right eye, the right eye planar image 33 showing only three surfaces of the top, front, and right sides of the cube 31 is visible.

If the left eye plane image 32 is reached in the left eye and the right eye plane image 33 is reached in the right eye, even if the object is not actually an object in front of the eye, the person may feel as if the person actually sees the cube 31.

As a result, in order to implement the stereoscopic image of the second category in the mobile terminal, the left eye image and the right eye image, which are seen at the same time with the same object, must be separated and reached through the display unit. Next, the 3D depth due to binocular disparity will be described with reference to FIG. 4.

4 is a conceptual diagram for explaining a sense of distance and 3D depth due to binocular parallax.

Referring to FIG. 4, when the hexahedron 40 is viewed at a distance d1 through both eyes, the lateral gravity of an image that enters each eye is relatively higher than that of the hexahedron 40 at a d2 distance, The difference is also great. In addition, the degree of three-dimensional feeling that a person feels when viewing the cube 40 at a distance d1 is greater than when the cube 40 is viewed at a distance d2. In other words, when a person looks at an object through both eyes, the closer to the object, the greater the three-dimensional feeling, and the farther the object, the less the three-dimensional feeling.

This difference in stereoscopic dimensions can be quantified to 3D depth or 3D level.

Next, an implementation method of the 3D stereoscopic image will be described.

As described above, in order to realize a 3D stereoscopic image, it is necessary that the right eye image and the left eye image are divided into two and reach the binocular. Various methods for this are described below.

1) Parallax barrier method

The parallax barrier method is a method of controlling a light propagation direction by electronically driving a blocking device provided between a general display unit and both eyes so that different images may be reached in both eyes.

This will be described with reference to FIG.

FIG. 5 is a conceptual diagram illustrating a method of implementing 3D stereoscopic images in a view barrier type display unit applicable to embodiments of the present invention.

The structure of the display barrier type display unit 151 for displaying a 3D stereoscopic image may have a configuration in which the switch liquid crystal 151b is combined with a general display device 151a. Using the switch liquid crystal 151b, the optical parallax barrier 50 may be operated as shown in FIG. 5 (a) to control the traveling direction of the light to separate the light to reach the left and right eyes. Therefore, when an image in which a right eye image and a left eye image are combined is displayed on the display device 151a, the image corresponding to each eye is seen from the user's point of view as if it is displayed in three dimensions.

In addition, as shown in FIG. 5B, the parallax barrier 50 by the switch liquid crystal is electrically controlled so that all of the light is transmitted, thereby eliminating separation of the light by the parallax barrier so that the same image can be seen by the left and right eyes. It may be. In this case, the same function as that of the general display unit may be performed.

5 illustrates that the parallax barrier moves in parallel in one axial direction, but the present invention is not limited thereto, and a parallax barrier capable of moving in parallel in two or more axial directions according to a control signal of the controller 180 may be used. have.

2) Lens refraction method

The lens refraction method (lenticular) is a method using a lenticular screen provided between a display part and a binocular eye, and a method of refracting a traveling direction of light through lenses on a lenticular screen so that different images are reached in both eyes.

3) polarized glasses system

Polarized light is polarized so that the directions of polarization are orthogonal to each other to provide different images in both directions or in the case of the circular polarized light so that the directions of rotation are different from each other.

4) Active shutter method

Eye image is alternately displayed at a predetermined cycle through the display unit and the user's eyeglasses are arranged such that when the image in the corresponding direction is displayed, the shutter in the opposite direction is closed, To reach the eye. That is, during the time when the left eye image is displayed, the shutter of the right eye is closed to allow the left eye image to be reached only in the left eye, and the shutter of the left eye is closed during the time when the right eye image is displayed.

It is assumed that the portable terminal according to an embodiment of the present invention described below can provide a 3D stereoscopic image to a user through the display unit 151 through any one of the above-described methods.

However, since the principle of the 3D image described above with reference to FIGS. 4 and 5 is a situation that assumes a three-dimensional object, the shape of the object is different in the left eye image and the right eye image. However, in the case of a planar object instead of a three-dimensional object, the shape of the object is the same in the left eye image and the right eye image. However, if the position where the object is arranged in each image is different, the user may feel the perspective of the object. In the present specification, for the sake of understanding, it is assumed that the stereoscopic image appearing below is a plane object. Of course, it is apparent that the present invention can be applied to a three-dimensional object.

The unit 141 is driven. In this case, the 3D menus 311, 312, and 313 may be upper or lower subordinate menus, or lower menus included in a specific menu.

If the determined proximity depth is a preset d1 depth, the controller 180 switches the first 3D menu 311 to a second 3D menu 312 as illustrated in FIG. 10B. Display.

In addition, the controller 180 displays the proximity depth of the user detected by the first proximity sensor 141A while the second 3D menu 312 is displayed, and the preset d2 depth d1 <d2 or d1> d2. As shown in FIG. 10C, the second 3D menu 312 is converted into the third 3D menu 313 and displayed.

As the distance from the first proximity sensor 141A increases, the third 3D menu 313 may gradually switch to display the first 3D menu 311.

In addition, the controller 180 may determine that the proximity depth of the user detected through the first proximity sensor 141A is a preset d2 depth d1 <in a state where the most 3D depth is given to the second 3D menu 312. d2 or d1> d2), as shown in (c) of FIG. 12, gives the third 3D menu 313 the most 3D depth so that the third 3D menu 313 looks closest to the user. And the smallest 3D depth is displayed on the second 3D menu 312 so that the existing second 3D menu 312 is viewed farthest.
