The mirror 124 allows the user to see his / her own face or the like when photographing (self-photographing) the user using the camera 121 '.

The sound output module 152 ′ may be further disposed on the rear side of the terminal body. The sound output unit 152 ′ may implement a stereo function together with the sound output module 152 (see FIG. 2A), and may be used to implement a speakerphone mode during a call.

In addition to the antenna for communication, a broadcast signal receiving antenna 116 may be additionally disposed on the side of the terminal body. The antenna 116 constituting a part of the broadcast receiving unit 111 (refer to FIG. 1) may be installed to be pulled out from the terminal body.

The terminal body is equipped with a power supply unit 190 for supplying power to the mobile terminal 100. The power supply unit 190 may be built in the terminal body or may be directly detachable from the outside of the terminal body.

The rear case 102 may be further equipped with a touch pad 135 for sensing a touch. The touch pad 135 may be of a light transmission type for the display unit 151. [ In this case, if the display unit 151 is configured to output visual information on both sides (i.e., in the direction of both the front and rear surfaces of the mobile terminal), the visual information may be recognized through the touch pad 135. do. The information output on both surfaces may be controlled by the touch pad 135.

Meanwhile, since a display dedicated to the touch pad 135 is separately installed, the touch screen may be disposed on the rear case 102.

The touch pad 135 operates in association with the display unit 151 of the front case 101. The touch pad 135 may be disposed in parallel to the rear of the display unit 151. The touch pad 135 may have the same or smaller size as the display unit 151.

Hereinafter, a 3D image representation method and a control process of a mobile terminal that can be applied in embodiments of the present invention will be described.

Stereoscopic images that can be implemented on the display unit 151 of the mobile terminal can be classified into two categories. The criterion of this division is whether different images are provided to both eyes.

First, the first stereoscopic image category will be described.

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 real of such a stereoscopic image may be referred to as a planar image.

The second category is a method in which different images are provided in both eyes (stereoscopic), and a method using the principle of feeling a three-dimensional feeling when a human sees an object with the naked eye. That is, two eyes of a person see different plane images when viewing the same object by the distance between them. These different planar images are delivered to the brain through the retina, and the brain fuses them to feel the depth and reality of the stereoscopic image. Therefore, although there are some differences between people, binocular disparity due to the distance between the two eyes makes a sense of three-dimensional feeling, and such binocular disparity becomes the most important element of the second category. Such binocular disparity will be described in more detail with reference to FIG. 3.

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 have been viewed with the same object at a predetermined time, 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 distance d2, and the image seen through both eyes is higher. 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. That is, when a person sees an object through both eyes, the closer the object is, the larger the three-dimensional effect is felt, and the farther the object is, the less the three-dimensional effect is felt.

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

Hereinafter, in the present specification, a high three-dimensional sense of a nearby object is represented by a low 3D depth and a low 3D level, and a low three-dimensional sense of a far-away object is represented by a high 3D depth and a high 3D level. This definition of 3D depth or 3D level is relative and its classification criteria and the direction of increase / decrease may be changed.

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

As described above, in order to implement a 3D stereoscopic image, the right eye image and the left eye image need to be divided and reached to both eyes. Various methods for this will be 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. 5.

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 the display unit and both eyes, and is a method of reaching different images in both eyes by refracting the traveling direction of light through the lenses on the lenticular screen.

3) polarized glasses

It is a method of providing different images in both eyes by making the polarization directions perpendicular to each other, or providing different images in both eyes by polarizing them so that the rotation directions are different from each other in the case of circular light.

4) Active Shutter Method

As a type of glasses, the right eye image and the left eye image are alternately displayed at predetermined intervals through the display unit, and the user's glasses close the shutter in the opposite direction when the image in the corresponding direction is displayed, so that the image in the corresponding direction is displayed in the corresponding direction. How to reach the eye. That is, the left eye image only reaches the left eye while the left eye image is displayed, and the left eye image reaches the right eye only while the right eye image is displayed.

In the above, the 3D image representation process according to the present invention has been described.

6 to 20, each embodiment according to the present invention will be described in detail.

First, the first embodiment according to the present invention will be described in detail with reference to FIGS. 6 to 12.

7 to 12 are screen state diagrams illustrating a process of converting and displaying a 2D thumbnail image into a 3D thumbnail image according to a first embodiment of the present invention.

The first embodiment of the present invention provides a function of converting an existing two-dimensional (hereinafter, referred to as '2D') thumbnail image into a 3D thumbnail image and displaying the converted 3D thumbnail image on the screen so as to be rotated and scrolled on a screen. to provide.

6 to 12, the controller 180 of the mobile terminal 100 receives a command signal for displaying 2D images stored in the memory 160 from the user through the user input unit 130 or the touch screen 151. When input, the thumbnail images 311a, 312a, 313a, 314a, 315a, and 316a in which a plurality of 2D images are displayed in a thumbnail manner are displayed on the screen of the touch screen 151 [S111] [FIG. 7 and FIG. 8].

In this case, an image source for 3D converting the 2D images and the 2D images is stored in the memory 160. The image source may be left eye and right eye images of each of the 2D images. An image source of each of the 2D images may be obtained from the outside through the wireless communication unit 110.

In this case, the thumbnail images 311a, 312a, 313a, 314a, 315a, and 316a may be arranged and displayed in a grid style as shown in FIG. 7, and as shown in FIG. 8. , And may be arranged in an ellipse or circle shape and displayed in a rotation style that is rotated clockwise or counterclockwise.

As described above, the controller 180 arranges and displays the 2D thumbnail images 311a, 312a, 313a, 314a, 315a, and 316a on the touch screen 151 as described above. When a scroll command for rotational movement of 311a, 312a, 313a, 314a, 315a, and 316a is input [S112], the 2D thumbnail images 311a, 312a, and 313a using image sources included in the memory 160 are input. , 314a, 315a, and 316a are converted into 3D thumbnail images 311b, 312b, 313b, 314b, 315b, and 316b [S113].

In this case, the user may instruct the scroll command to the controller 180 by using any one of the user input unit 130, the touch screen 151, and the motion sensor 142.

For example, the user may operate a jog wheel or a jog switch provided in the user input unit 130 in a left to right direction, a right to a left direction, an up to a down direction, a down to a top direction, a clockwise direction, or a counterclockwise direction. The controller 180 may instruct the scroll command.

As another example, the user drags the touch screen 130 in a left → right direction, right → left direction, up → down direction, down → up direction, clockwise direction, counterclockwise direction, and the like to the controller 180 to scroll the scroll. You can direct the command.

As another example, when the user moves the main body 100 of the mobile terminal in a left → right direction, right → left direction, up → down direction, down → up direction, clockwise direction, counterclockwise direction, the motion sensor 142 Detects a motion of the user's main body 100, and outputs a signal corresponding to the detected motion to the controller 180 to instruct the controller 180 to scroll.

As described above, the controller 180 converts the 2D thumbnail images 311a, 312a, 313a, 314a, 315a, and 316a into 3D thumbnail images 311b, 312b, 313b, 314b, 315b, and 316b. After the converted 3D thumbnail images 311b, 312b, 313b, 314b, 315b, and 316b are aligned and displayed on the touch screen 151 in a rotating style, the 3D thumbnail images 311b corresponding to the scroll command of the user are displayed. , 312b, 313b, 314b, 315b, and 316b are rotated and moved [S114].

In this case, as shown in FIGS. 9 and 10, the controller 180 rotates the 3D thumbnail images 311b, 312b, 313b, 314b, 315b, and 316b to rotate the 3D thumbnail images 311b, The 3D thumbnail images 311b, 312b, 313b, 314b, 315b, and 316b may be further provided to the user by adjusting the sizes and 3D depth values of 312b, 313b, 314b, 315b, and 316b. .

That is, referring to FIG. 9A, when the controller 180 rotates 3D thumbnail images 311b, 312b, 313b, 314b, 315b, and 316b, a reference position in the screen of the touch screen 151 is displayed. Gradually increase the size of the 3D thumbnail images 311b, 312b, 313b, 314b, 315b, and 316b in order of proximity to the 3D thumbnail images 311b, 312b, 313b, The sizes of 314b, 315b, and 316b may be gradually reduced to provide a three-dimensional feeling to the user.

In this case, in FIG. 9, the reference distance is the center of the lowermost part of the screen of the touch screen 151, and the 3D thumbnail image corresponding to “313b” is positioned closest to the reference distance with the first rank and displayed the largest. 3D thumbnail images corresponding to reference numerals “311b and 315b” are smaller than the 3D thumbnail images corresponding to “313b” by being located closest to the second distance at a second order and corresponding to “312b and 316b”. 3D thumbnail images are located closer to the reference distance in the third order than the 3D thumbnail images corresponding to “311b and 315b”, and the 3D thumbnail images corresponding to “314b” are farthest from the reference distance. Because it is located, it is displayed the smallest.

In this case, although the reference distance is illustrated as being the center of the lowermost part of the screen of the touch screen 151, the present invention is not limited thereto. That is, the reference distance may be a position where a highlight is displayed on the screen of the touch screen 151.

In addition, as shown in FIG. 9B, the controller 180 aligns the 3D thumbnail images 311b, 312b, 313b, 314b, 315b, and 316b in a rotational style as shown in FIG. 9A. In the display state, if a scroll command for rotating the 3D thumbnail images 311b, 312b, 313b, 314b, 315b, and 316b by one counterclockwise direction is input from the user, the controller 180 again returns the reference. Gradually increase the sizes of the 3D thumbnail images 311b, 312b, 313b, 314b, 315b, and 316b in order of approaching a distance, and in order of moving away from the reference position, the 3D thumbnail images 311b, 312b, and 313b. 314b, 315b, and 316b) gradually decrease in size.

In addition, referring to FIG. 10A, the controller 180 rotates 3D thumbnail images 311b, 312b, 313b, 314b, 315b, and 316b in a reference position on the screen of the touch screen 151. Gradually decrease the 3D depth values of the 3D thumbnail images 311b, 312b, 313b, 314b, 315b, and 316b in the order of approaching to the 3D thumbnail images 311b, 312b, 313b, 314b, 315b, and 316b may be gradually increased in size to provide a three-dimensional feeling to the user.

In this case, as the size increases, the 3D depth value gives the user a feeling that the image is reduced, and as the size decreases, the 3D depth value gives the user a feeling that the image is enlarged.

Hereinafter, in the present specification, a high three-dimensional sense of a nearby object is represented by a low 3D depth and a low 3D level, and a low three-dimensional sense of a far-away object is represented by a high 3D depth and a high 3D level. This definition of 3D depth or 3D level is relative and its classification criteria and the direction of increase / decrease may be changed.

 That is, in FIG. 10, the reference distance is the center of the lowermost part of the screen of the touch screen 151, and the 3D thumbnail image corresponding to “313b” is located closest to the reference distance in the first order and has the smallest 3D. 3D thumbnail images corresponding to the depths "311b and 315b" are displayed at a 3D depth larger than the 3D thumbnail images corresponding to "313b" by being located close to the second distance in the second order at the reference distance. 3D thumbnail images corresponding to 312b, 316b "are located closer to the reference distance in the third order, and are displayed with a larger 3D depth than 3D thumbnail images corresponding to" 311b, 315b ", and have a 3D corresponding to" 314b ". Thumbnail images are displayed at the largest 3D depth because they are located farthest from the reference distance.

Also, as shown in FIG. 10B, the controller 180 aligns the 3D thumbnail images 311b, 312b, 313b, 314b, 315b, and 316b in a rotational style as shown in FIG. 10A. In the display state, if a scroll command for rotating the 3D thumbnail images 311b, 312b, 313b, 314b, 315b, and 316b by one counterclockwise direction is input from the user, the controller 180 again returns the reference. Gradually decreases the 3D depth values of the 3D thumbnail images 311b, 312b, 313b, 314b, 315b, and 316b in the order of approaching the distance, and the 3D thumbnail images 311b and 312b in an order away from the reference position. 313b, 314b, 315b, and 316b) gradually increase the 3D depth value.

In addition, although not shown in the drawing, the controller 180 moves the 3D thumbnail images 311b, 312b, 313b, 314b, 315b, and 316b to move to a reference position within a screen of the touch screen 151. The brightness of the 3D thumbnail images 311b, 312b, 313b, 314b, 315b, and 316b is gradually increased in order, and the 3D thumbnail images 311b, 312b, 313b, and 314b are sequentially moved away from the reference position. The brightness values of 315b and 316b may be gradually decreased to provide a three-dimensional feeling to the user.

Meanwhile, when the 3D thumbnail images are selected while the 3D thumbnail images 311b, 312b, 313b, 314b, 315b, and 316b are rotated by FIGS. 9 and 10, [S115]. ], The 3D thumbnail image is gradually displayed on the entire screen of the touch screen 151 by gradually increasing or decreasing the size or 3D depth value of the selected 3D thumbnail images [S116].

That is, referring to FIG. 11, when the 3D thumbnail image corresponding to “313b” is selected (FIG. 11A), the controller 180 sets the size of the selected 3D thumbnail image 313b to its initial size. It can be gradually increased (FIG. 11 (b)), and can be displayed on the whole screen of the touch screen 151 (FIG. 11C).

In addition, referring to FIG. 12, when the 3D thumbnail image corresponding to “313b” is selected (FIG. 12A), the controller 180 selects a 3D original 3D depth level of the selected 3D thumbnail image 313b. The first 3D depth level is first displayed on the entire screen of the touch screen 151 at a higher 3D depth level (FIG. 12 (b)), and then gradually increased by the original 3D depth level. (C) of FIG. 12].

15 to 18, the controller 180 of the mobile terminal 100 displays a plurality of 3D UI objects 410, 420, 430, and 440 to which a specific function is assigned on the screen of the touch screen 151. [S311] [Fig. 16].

In this case, in FIG. 16, the functions of the 3D UI objects 410, 420, 430, and 440 may be assigned a camera menu function, a message menu function, a broadcast menu function, and a music menu function. The function assigned to the 3D UI objects 410, 420, 430, and 440 according to the present invention is not limited thereto. That is, the functions assigned to the 3D UI objects 410, 420, 430, and 440 may be all menu functions included in the mobile terminal 100, and may be contents in some cases.

That is, the content includes text, images, received messages, contact information in the phonebook, audio files, photo files, video files, game files, schedule information, document files, and electronic dictionary files. , Calculator files, and web page address information may be displayed in the form of 3D UI objects.

In addition, as shown in FIG. 17, the 3D UI objects 410, 420, 430, and 440 may be preset with importance by the user.

In addition, the controller 180 may determine the frequency of use of the 3D UI objects 410, 420, 430, and 440 for a predetermined period of time, and set the importance according to the rank of the identified usage frequency.

That is, referring to FIG. 17, the message menu UI object 420 is set to have a higher importance level than other UI objects 410, 430, and 440 by the user.

In addition, if there is no importance setting of the message menu UI object 420 for the user, the controller 180 determines that the frequency of use of the message menu UI object 420 (“40 times”) is different from other UI objects 410, 430, and the like. Since it is greater than 440, the importance is also set as the largest first rank.

In addition, the music menu UI object 440 is set higher than other UI objects 410 and 430 except the message menu UI object 420 by the user.

In addition, if there is no importance setting of the music menu UI object 440 for the user, the controller 180 determines that the frequency of use of the music menu UI object 440 ("30 times") excludes the message menu UI object 420. Since it is larger than other UI objects 410 and 430, importance is also set as a second rank.

In addition, the camera menu UI object 410 has a higher importance level than the other UI objects 430 except for the message menu UI object 420 and the music menu UI object 440 by the user.

In addition, if there is no importance setting of the camera menu UI object 410 for the user, the controller 180 determines that the frequency of use (“20 times”) of the camera menu UI object 410 is the message menu UI object 420 and the music. Since it is larger than other UI objects 430 except for the menu UI object 440, the importance is also set as the third rank.

Finally, the broadcast menu UI object 430 is set lower than other UI objects 410, 420, and 440 by the user.

In addition, if there is no importance setting of the broadcast menu UI object 410 for the user, the controller 180 determines that the frequency of use of the broadcast menu UI object 410 ("10 times") is different from other UI objects 410, 420, and 440. The importance is also set to the fourth lowest rank as smallest than).

As described with reference to FIG. 17, the controller 180 determines the importance or frequency of use set in each of the 3D UI objects 410, 420, 430, and 440 [S312], and the determined importance or frequency of use is ranked. Each of the 3D UI objects 410, 420, 430, and 440 is displayed to be identified with each other [S313].

In other words, the controller 180 may display the identified 3D UI objects 410, 420, 430, and 440 by adjusting the sizes and 3D depth values of the 3D UI objects in the order of increasing rank.

FIG. 18A illustrates a state in which the 3D UI objects 410, 420, 430, and 440 are displayed on the screen of the touch screen 151 as shown in FIG. 16. The priority or frequency of use of each of the 3D UI objects 410, 420, 430, and 440 is determined.
