As shown in FIG. 4, when a pointer such as a viewer's face is close to the touch screen, the proximity sensor 141 disposed inside or near the touch screen detects this and outputs a proximity signal.

The proximity sensor 141 may be configured to output different proximity signals according to a distance between the pointer positioned close to the display unit 151 (hereinafter, referred to as "proximity depth").

In FIG. 4, for example, a cross-sectional view of the display unit 151 in which the proximity sensors 141 that sense three proximity depths are disposed is illustrated. However, of course, a proximity sensor that detects more than four proximity depths is also possible.

In detail, when the pointer is completely in contact with the display unit 151 (a ₀ ), it is recognized that the viewer is in contact with the display unit 151. When the pointer is positioned below the distance a ₁ on the display unit 151, it is recognized that the viewer is located at the distance a ₁ from the display unit 151. When the pointer is spaced a distance less than a ₁ over a distance ₂ position on the display unit 151 has is recognized that the viewer located at a distance ₂ from the display section 151. When the pointer is spaced less than a distance ₂ over a distance ₃ position on the display unit 151, the position is recognized that the distance a ₃ from the display section 151 to a viewer will be described later. When the pointer is positioned at a distance of more than a ₃ distance from the display unit 151, it is recognized that the operation of the proximity sensor 141 is released.

Therefore, the controller 180 may recognize how far (D) the user is from the display unit 151 (or the image panel 155 to be described later) according to the proximity depth and the proximity position of the pointer as various input signals. Various operation control according to the various input signals may be performed.

In addition, in the present invention, by using the plurality of proximity sensors 141 distributed in a plurality of directions in the display unit to detect proximity gibs and proximity positions of a plurality of regions, the above-described principle of the proximity sensor 141 is used. As a result, the viewer's binocular center (M) can sense the degree of deflection from the vertical center axis (C) of the display unit 151 to be described later.

In addition, the sensing unit 140 may be a distance sensor 142.

The distance sensor 142 may be located on the surface or inside the viewer and the mobile terminal 100. The distance sensor 142 is a device that can measure the distance (D) to the object (in this case, the viewer) located in front of, for example, the time difference that the emitted ultrasonic wave is reflected back to the object to measure the distance The method of calculating the distance by measuring can be used. There are also ways to use infrared or laser.

In addition, the sensing unit 140 may be a camera 121 of the A / V input unit. Preferably, the camera 121 may be a video telecommunication camera.

In this case, the camera 121 is used as an eye detection device in conjunction with a control unit to be described later, and for this purpose, the camera 121 acquires a viewer's face image and the second unit 180 performs an operation on the acquired face image. The boundary line is extracted by the contrast difference, and the controller 180 analyzes the significant contrast difference between the eye conjunctiva and the pupil by a histogram or the like to detect the position of both eyes of the viewer. The distance between the two eyes and the position of the center of both eyes M (that is, the center of the distance between the both eyes) are measured from the positions of both eyes detected by the camera 121. The distance D between the viewer and the display unit 151 corresponding to the distance between the two eyes is calculated from the controller 180 to be described later, and the center of both eyes M and the vertical center axis C of the display unit 151 are calculated. The deflection angle θ formed is calculated from the controller 180 to be described later. In general, the greater the distance between both eyes measured by the camera, the greater the distance between the viewer and the display. However, the present invention is not limited to this.

5 schematically shows a display unit 151 according to the present invention. As shown in FIG. 5, the display unit 151 includes an image panel 155 for displaying an image and a barrier layer 156 for allowing a viewer to recognize an image displayed on the image panel 155 as a stereoscopic image. Include. Here, the barrier layer 156 is preferably configured in a parallax barrier manner.

The imaging panel 155 is preferably a panel capable of displaying both 2D and 3D images (stereoscopic images). The image panel 155 may include a plurality of pixels or subpixels, and may be, for example, one of an LCD such as an LED, an STN-LCD, or a TFT-LCD, an OLED such as a PMOLED, or an AMOLED. When the image panel 155 represents a stereoscopic image, the image panel 155 alternately displays the left eye image 155a and the right eye image 155b in parallel, and each of the left eye image 155a or each right eye. The image 155b may appear in units of each pixel or each subpixel of the image panel 155. Hereinafter, each left eye image 155a or each right eye image 155b will be described on a pixel basis.

The barrier layer 156 is arranged at a position spaced apart from the image panel 155 by a predetermined distance in front of the image panel 155. In the barrier layer 156, when the image panel 155 alternately displays the left eye image 155a and the right eye image 155b, only the left eye image 155a is in the viewer's left eye, and only the right eye image 155b is in the viewer's right eye. It plays a role in making it happen. To this end, the barrier layer 156 includes a plurality of light blocking portions 157 and a gap (also referred to as a light transmitting portion) between the plurality of light blocking portions 157, and due to the light blocking portions 157 The left eye image 155a of the image panel 155 may not be formed in the right eye of the viewer, and the right eye image 155b of the image panel 155 may not be formed in the left eye of the viewer.

The barrier layer 156 is composed of a plurality of subpixels 156a, and the subpixel 156a of the barrier layer 156 is a unit pixel of each left eye image 155a of the image panel 155 or each right eye. The size (or pitch) is smaller than the unit pixel of the image 155b. For example, as illustrated in FIG. 5, the subpixel 156a of the barrier layer 156 may include a unit pixel of each left eye image 155a or a unit pixel of each right eye image 155b. It may be formed to correspond to the five subpixels 156a of the 156. Of course, the number of subpixels 156a of the barrier layer 156 corresponding to the unit pixels of the image panel 155 may be further increased or decreased.

In addition, the barrier layer 156 may be a panel similar to the image panel 155, but is preferably a transparent OLED (TOLED) panel. The TOLED panel is a transparent panel like glass when no power is supplied to the panel and can display an image when the panel is powered. In this way, when the barrier layer 156 is formed of a TOLED panel, when the 2D image appears on the image panel 155, the light blocking portion 157 of the barrier layer 156 is turned off to allow the viewer to block the light blocking portion 157. The 2D image can be seen clearly without disturbing the field of view. That is, by configuring the barrier layer 156 as a TOLED panel, the viewer can selectively view both 2D and 3D images with one mobile terminal 100.

Since the TOLED panel of the barrier layer 156 only needs to form the light blocking portion 157 when the power is supplied, the TOLED panel of the barrier layer 156 preferably shows only a single color (for example, black) and not a plurality of colors. It is a TOLED panel. As such, by using the monochromatic TOLED, the manufacturing cost of the barrier layer 156 can be reduced.

Since the barrier layer 156 is composed of a TOLED composed of a plurality of subpixels 156a, the position and the length of the light blocking unit 157 and the light blocking unit 157 are corresponding to the position of the viewer, as will be described later. The interval of the can be freely controlled through the controller 180.

The controller 180 receives the location information of the viewer from the sensing unit 140 and controls the image panel 155 or the barrier layer 156 using the received location information of the viewer. In particular, the controller 180 may adjust the length of the light blocking unit 157 of the barrier layer 156 or the interval between the plurality of light blocking units 157 according to the viewer's position information received from the sensing unit 140. Or adjust the displacement (for example, the degree of movement and the direction of movement) of the light blocking portion 157.

When the location information of the viewer sensed by the sensing unit 140 is the distance D between the display unit 151 and the viewer, the controller 180 controls the preset or stored in the memory 160 of the mobile terminal. The length determination value of the light blocking unit 157 or the distance determination value between the plurality of light blocking units 157 corresponding to the distance D between the display and the viewer is searched among the variables. Here, the length determination value or the interval determination value corresponding to D means the length or light of the light blocking portion that can form the focal position of the stereoscopic image that enables the viewer to clearly view the stereoscopic image when the viewer is at the distance D. The gap between the blocks.

The distance D between the display unit 151 and the viewer preset or stored in the memory 160 of the mobile terminal and the corresponding length of the light blocking unit 157 or the plurality of light blocking units 157. Interval determination values between are shown in the data table of FIG. However, the data table of FIG. 6 is exemplary and the present invention is not limited thereto.

As shown in FIG. 6, for example, when the distance D between the display unit 151 and the viewer is 25 cm, the length determination value of the light blocking unit 157 is “1111” and the light blocking unit 157 The spacing determination value between the points is " 000000 ". As will be described later, when the controller 180 turns on / off the subpixel 156a of the barrier layer 156 to correspond to the length determination value and the interval determination value when D is 25 cm, the barrier as shown in FIG. A pattern (that is, the light blocking portion 157) can be obtained.

In this way, since the length determination value or the interval determination value is preset or stored in the memory 160, the length determination value and the interval determination value corresponding to the user position from the sensing unit 140 may be retrieved. According to the position of the user in each case, a separate calculation processor for calculating the distance between the corresponding light blocking portion 157 and the distance between the light blocking portions 157 is not required, thereby reducing the number of parts. Therefore, the manufacturing cost can be reduced, and the time required from the position detection process of the viewer to the formation of the light blocking unit 157 can be significantly shortened, thereby providing a clear three-dimensional image to the viewer more quickly.

After the control variable search step is completed in the memory 160, the controller 180 may determine the length determination value of the light blocking unit 157 retrieved from the memory 160 and the interval determination value between the plurality of light blocking units 157. Correspondingly, the on / off of each subpixel 156a of the barrier layer 156 is controlled, with the result illustrated by way of example in FIG. 7.

As shown in FIG. 7, the barrier layer 156 is determined by the controller 180 according to the length determination value of the light blocking unit 157 and the distance determining value between the plurality of light blocking units 157, which are retrieved from the memory 160. The light blocking portion 157 is formed by controlling ON / OFF of each subpixel 156a of the " At this time, "1" is the ON state of the subpixel 156a of the barrier layer 156 in the detected length determination value of the light blocking portion 157 and the gap determination value between the plurality of light blocking portions 157. When the subpixel 156a of the barrier layer 156 is in an ON state, the subpixel 156a of the barrier layer 156 becomes the light blocking unit 157. On the contrary, "0" in the detected length determination value of the light blocking portion 157 and the interval determination value between the plurality of light blocking portions 157 is in the OFF state of the subpixel 156a of the barrier layer 156. When the subpixel 156a of the barrier layer 156 is in an OFF state, the subpixel 156a of the barrier layer 156 becomes a gap between the light blocking units 157.

FIG. 8 shows the length of the light blocking portion 157 of the barrier layer 156 and the spacing between the plurality of light blocking portions 157 when D is 45 cm.

As described above, the controller 180 may determine the length determination value (herein, “11”) and the light blocking unit 157 of the light blocking unit 157 among the control variables stored in the memory 160 as shown in the table of FIG. 6. After retrieving the spacing determination value (here, "00000000") between the pixels, the viewer controls the on / off of each subpixel 156a of the barrier layer 156 according to the determination value, so that the viewer , The position of D is 45cm) to control the three-dimensional image to see clearly.

7 and 8, it can be seen that the light blocking portion shown in FIG. 8 has a shorter length (reduced by two subpixels) than the light blocking portion shown in FIG. 7. In general, it can be seen that as D increases, the length of the light blocking portion is shortened. However, this is an exemplary case and the present invention is not limited thereto.

Hereinafter, the barrier pattern will be described when the viewer deviates from the left or right from the vertical center axis C of the display unit 151 when D is 25 cm among the data in the data table of FIG. 6.

The position information of the viewer detected by the sensing unit 140 is about the vertical center axis C of the display unit 151 (or the image panel 155), which is preset or stored in the memory 160 of the mobile terminal. In the case of the deflection angle θ of the viewer's binocular center M, the controller 180 may control the vertical center axis C of the display unit 151 among control variables preset or stored in the memory 160 of the mobile terminal. The displacement determination value corresponding to the degree of movement and the direction of movement of the light blocking portion 157 corresponding to the deflection angle θ of the viewer's binocular center M with respect to is retrieved.

The deflection angle θ of the viewer's binocular center M with respect to the vertical center axis C of the display unit 151 (or the image panel 155), which is preset or stored in the memory 160 of the mobile terminal, and The displacement determination value of the light blocking portion 157 corresponding thereto is shown in the data table of FIG. 9. However, the table of FIG. 9 is exemplary and the present invention is not limited thereto. Here, the displacement determination value corresponding to θ refers to the degree of movement and the direction of movement of the light blocking unit capable of forming the focal position of the stereoscopic image that enables the viewer to clearly view the stereoscopic image when the viewer is located at θ. In addition, "+" in front of the deflection angle means that the viewer's binocular center (M) is deflected to the left with respect to the vertical center axis (C) of the display unit, and "-" in front of the deflection angle indicates the viewer's binocular center ( M) is deflected to the right with respect to the vertical center axis C of the display unit.

6 and 9, for example, when the deflection angle θ is 0 (that is, when the viewer is not deflected at all), the displacement determination value of the light blocking unit 157 is "000001111000000111100000011110", When the deflection angle θ is +10 degrees, the displacement determination value of the light blocking portion 157 is "000111100000011110000001111000". As will be described later, the controller 180 turns on / off the subpixel 156a of the barrier layer 156 to correspond to the displacement determination value when the deflection angle θ is +10 degrees. A pattern (that is, the light blocking portion 157) can be obtained.

In this way, since the displacement determination value is preset or stored in the memory 160, the displacement determination value corresponding to the position of the user from the sensing unit 140 may be retrieved. It does not need a separate calculation processor for calculating the degree of movement and the direction of movement of the light blocking unit 157, which can reduce the number of manufacturing parts, thereby reducing the manufacturing cost, the viewer's location information detection process Time required for the formation of the light blocking unit 157 can be significantly shortened, thereby providing a clear stereoscopic image more quickly to the viewer.

After completing the control variable search step in the memory 160 of the mobile terminal, the controller 180 corresponds to each of the sublayers of the barrier layer 156 to correspond to the displacement determination value of the light blocking unit 157 retrieved from the memory 160. The ON / OFF of the pixel 156a is controlled, with the result shown by way of example in FIG. 10.

As shown in FIG. 10, the controller 180 turns on / off each of the subpixels 156a of the barrier layer 156 according to the displacement determination value of the light blocking unit 157 retrieved from the memory 160. ON / OFF) to form the light blocking portion 157. At this time, "1" in the detected displacement determination value of the light blocking unit 157 corresponds to the ON state of the subpixel 156a of the barrier layer 156, and the subpixel 156a of the barrier layer 156. In this ON state, the subpixel 156a of the barrier layer 156 becomes the light blocking portion 157. On the contrary, "0" in the detected length determination value of the light blocking portion 157 or the gap determination value between the plurality of light blocking portions 157 is in the OFF state of the subpixel 156a of the barrier layer 156. When the subpixel 156a of the barrier layer 156 is in an OFF state, the subpixel 156a of the barrier layer 156 becomes a gap between the light blocking units 157.

That is, the controller 180 controls the search in the memory 160 and the on / off of each of the subpixels 156a of the barrier layer 156, so that the light blocking unit (if the deflection angle θ is +10 degrees). 157 controls the barrier layer 156 (i.e., light shield 157) such that the viewer moves two subpixels 156a to the left than the displacement determination value which is not biased at all.

Therefore, according to the mobile terminal 100 according to the present invention, the viewer can clearly see the stereoscopic image at the current position at any position with respect to the mobile terminal 100, the viewer while viewing the stereoscopic image to the original position Viewers can still watch stereoscopic images clearly.

Preferably, the mobile terminal 100 according to the present invention may further include a user input unit capable of selecting an operation mode of the stereoscopic image focal position control. The user input unit capable of selecting an operation mode of the stereoscopic image focal position control may be, for example, a keypad of one of a button formed on the outside of the mobile terminal 100 or a virtual keypad of a touch screen. This is not restrictive.

Here, the operation mode of the stereoscopic image focal position control is composed of a first mode and a second mode. In the first mode, the sensing unit 140 detects the viewer's location information once for a predetermined time before or after displaying the stereoscopic image on the display, and the controller 180 detects the sensing unit 140 for the predetermined time. Size and position of the light blocking unit 157 of the barrier layer 156 by controlling on / off of the plurality of subpixels 156a of the barrier layer 156 once according to the position information detected by It is a mode to fix it. On the other hand, in the second mode, the sensing unit 140 detects the viewer's location information in real time or periodically during the display of the stereoscopic image, the control unit 180 by the sensing unit 140 in real time or periodically The light blocking unit 157 of the barrier layer 156 is controlled in real time or periodically by controlling on / off of the plurality of subpixels 156a of the barrier layer 156 according to the detected position information. This mode changes periodically.

In the first mode, since the sensing unit 140 is operated only once for a predetermined time and each sub-pixel 156a of the barrier layer 156 is controlled once, the power supply unit 190 of the mobile terminal 100 is a battery. Since the consumption time is small, the use time of the mobile terminal 100 is long, and the second mode changes the light blocking unit 157 in real time or periodically even if the viewer moves the position during stereoscopic image display. There is an advantage that the viewer can always watch a clear three-dimensional image at their current location without having to move a different position. The viewer can freely select the first mode or the second mode at any time through the user input unit in order to view the optimal stereoscopic image in consideration of the remaining battery capacity and comfortable viewing posture.

Hereinafter, a method of controlling a mobile terminal for controlling a focus position of a stereoscopic image in the mobile terminal 100 according to the present invention will be described.

11 is a flowchart illustrating a step of selecting an operation mode of focus position control of a stereoscopic image.

In view of the remaining battery power and comfortable viewing posture, the viewer is allowed to execute the first mode and the control method of the mobile terminal in real time so that the control method of the mobile terminal according to the present invention is executed once as shown in FIG. 11. The second mode can be selected.

When the viewer selects the second mode, the controller determines in real time whether the location information of the viewer has changed, and controls the mobile terminal to repeat the control method of the mobile terminal according to the present invention when the location information of the viewer is changed. .

When the viewer selects one of the first mode and the second mode, the following control method of the mobile terminal is executed.

12 is a flowchart illustrating a first embodiment 200 of a method for controlling a mobile terminal according to the present invention.

First, the position information of the viewer with respect to the display unit 151 is sensed through the sensing unit 140 (230, 231, 233). In this case, the location information of the viewer is preferably the distance D and the deflection angle θ between the display unit 151 and the viewer as described above.

Thereafter, the controller 180 determines the length of the light blocking unit 157 of the barrier layer 156 or the light blocking units 157 in response to the position information of the viewer detected in the location information detecting step. At least one or more control variables of the gap determination value between the two or the displacement determination value of the light blocking unit 157 are retrieved from the memory 160 of the mobile terminal (251, 253).

Thereafter, the controller 180 controls the length, interval, or displacement of the barrier layer 156 according to the interval determination value, the interval determination value, or the displacement determination value retrieved in the control variable search step (270). This allows viewers to see stereoscopic images clearly at their current location.

Specifically, when the viewer's location information is the distance (D) between the display and the viewer, the location information sensing step is performed by measuring (231) the distance (D) between the display and the viewer.

After measuring the distance D, the controller 180 determines the length of the light blocking unit 157 corresponding to the distance D measured in the distance measuring step among the control variables in the memory 160 of the mobile terminal. In operation 251, the interval determination value between the light blocking units 157 is searched for. After retrieving the control variable, the controller 180 turns on / off the subpixel 156a of the barrier layer 156 according to the length determination value and the interval determination value retrieved in the control variable retrieval step. (270). As a result, the viewer can clearly see the stereoscopic image at his current location.

Also specifically, when the viewer's location information is the degree of deflection of the viewer's binocular center (M) with respect to the center of the display, the location information detecting step includes the viewer's binocular center (M) with respect to the vertical center axis (C) of the display. This is performed by measuring 233 the deflection angle θ to be formed.

After measuring the deflection angle θ, the control unit 180 corresponds to the light corresponding to the deflection angle θ of the binocular center M measured in the deflection degree measurement step among the control variables in the memory 160 of the mobile terminal. The displacement determination value, which is the movement degree and the movement direction of the blocking unit 157, is retrieved (253). After retrieving the control variable, the controller 180 controls on / off of the subpixel 156a of the barrier layer 156 according to the displacement determination value retrieved in the control variable retrieval step (270). As a result, the viewer can clearly see the stereoscopic image at his current location.

13 is a flow chart illustrating a second embodiment 300 of a method for controlling a mobile terminal according to the present invention.

First, the sensing unit 140 measures the distance D between the display and the viewer (320). In this case, the sensing unit 140 may be one of the proximity sensor 141, the distance sensor 142, or the camera 121 as described above.

Thereafter, the controller 180 determines a length determination value of the light blocking portion 157 of the barrier layer 156 and an interval determination value of the light blocking portions 157 corresponding to the distance D measured by the sensing unit 140. In operation 330, the memory 160 of the mobile terminal is searched. In this case, data as shown in the tables of FIGS. 6 and 9 are previously stored or preset in the memory 160 of the mobile terminal.

Thereafter, the controller 180 controls on / off of the plurality of subpixels 156a of the barrier layer 156 according to the length determination value and the interval determination value retrieved from the memory 160 of the mobile terminal (340). .

Subsequently, the controller 180 determines whether the viewer (that is, the viewer's binocular center M) is biased with respect to the center of the display unit 151 (that is, the vertical center axis C) through the sensing unit 140. Determine (350). In this case, the sensing unit 140 is preferably a camera 121 having an eye detection function.

If it is determined that the viewer's binocular center M is not biased with respect to the vertical center axis C of the display unit 151, the controller 180 terminates the control method of the mobile terminal and controls to display a stereoscopic image. do.

On the other hand, when it is determined that the viewer's binocular center M is biased with respect to the vertical center axis C of the display unit 151, the controller 180 senses that the sensing unit 140 is vertical to the display unit 151. The control is performed to measure the deflection angle θ formed by the viewer's binocular center M with respect to the central axis C (360).

Thereafter, the controller 180 determines a displacement determination value that is a movement direction or degree of movement of the light blocking unit 157 of the barrier layer 156 corresponding to the deflection angle θ measured by the sensing unit 140. Search in memory 160 (370).

Thereafter, the controller 180 controls on / off of the plurality of subpixels 156a of the barrier layer 156 according to the displacement determination value retrieved from the memory 160 of the mobile terminal (380).

Thereafter, the controller 180 ends the control method of the mobile terminal and controls the display unit 151 to display a stereoscopic image.

14 is a flowchart illustrating a modified embodiment 300 'of the method for controlling a mobile terminal according to the second embodiment of the present invention.

The control method 300 'of the mobile terminal according to the modified embodiment includes all the steps included in the control method 300 of the mobile terminal according to the second embodiment, but the order is different.

Specifically, in the control method 300 ′ of the mobile terminal according to the modified embodiment, first, the viewer (ie, the center of both eyes of the viewer M) is the center of the display unit 151 through the sensing unit 140. Determining whether the deflection with respect to the vertical center axis (C) is performed (350), and if it is determined that the viewer is not deflected with respect to the center of the display unit, measuring the distance between the viewer and the display unit (320) ), Retrieving the length determination value and the interval determination value 330 and controlling the barrier layer 340 are performed sequentially. On the contrary, if it is determined that the viewer is biased with respect to the center of the display unit, measuring the degree of deflection 360, retrieving the displacement determination value 370, controlling the barrier layer 380, viewer and display Measuring 320 the distance between the units, retrieving the length and spacing determination values 330 and controlling the barrier layer 340 are performed sequentially.

Hereinafter, a description will be given of a mobile terminal in which each step of the focus position control method of the stereoscopic image is displayed on the stereoscopic image display so as to inform the user of each step of the control method of the mobile terminal according to the present invention. Hereinafter, although the viewer is implemented as a virtual keypad on the touch screen as a means for inputting his or her choice, the present invention is not limited thereto.

A mobile terminal according to the present invention includes a stereoscopic image display for outputting stereoscopic images or information related to stereoscopic images; And a controller 180 for controlling the stereoscopic image display.

FIG. 15 exemplarily illustrates displaying the image on the stereoscopic image display so that the user can select whether to activate the focus position control function of the stereoscopic image. Here, the controller 180 displays whether the focus position control function of the stereoscopic image is activated (that is, indicated by “3D A / F?” In FIG. 13) 400 on the stereoscopic image display.

As shown in FIG. 15, when the viewer selects the confirmation 401, the controller 180 activates the focus position control function of the stereoscopic image according to the present invention, and when the viewer selects the cancel operation 403, the controller 180 Does not activate the focus position control function of the stereoscopic image according to the present invention.

FIG. 16 exemplarily illustrates displaying on a stereoscopic image display so that a user may select a focus position control mode 410 of the stereoscopic image. Here, displaying the selection of the focus position control mode of the stereoscopic image (indicated by "3D A / F mode selection" 410 in FIG. 14) on the stereoscopic image display is performed by the controller 180. The focus position control mode of the stereoscopic image may include a first mode (“Mode 1”) 411 for automatically adjusting the focal position of the stereoscopic image once and a second for automatically adjusting the focal position of the stereoscopic image in real time or periodically. A mode ("Mode 2") 413.

17 and 18 show the mode currently being operated on the stereoscopic image display to inform the viewer that the mode selected by the viewer in the selection 410 of the focal position control mode of the stereoscopic image is in operation (412, 414). ) Is shown by way of example. As shown in FIGS. 15 and 16, when the mode selected by the viewer in the selection 410 of the focus position control mode of the stereoscopic image is the first mode, “3D M1 412” is displayed on the stereoscopic image display. When the mode selected by the viewer in the selection 410 of the focus position control mode of the stereoscopic image is the second mode, the 3D M2 414 is displayed on the stereoscopic image display.

FIG. 19 schematically illustrates displaying a 420 on a stereoscopic image display when the viewer moves out of the focal position of the stereoscopic image during the stereoscopic image display when the focus position control mode of the stereoscopic image is the first mode. FIG. 18 schematically illustrates displaying the selection 410 of the focus position control mode of the stereoscopic image on the stereoscopic image display in FIG. 17 again.

When the viewer selects the second mode 413 in the selection 410 of the focus position control mode of the stereoscopic image, the viewer automatically controls the focal position of the stereoscopic image even when the viewer is out of the focal position of the stereoscopic image. When the viewer selects the first mode 411 in the selection position 410 of the focus position control mode of the stereoscopic image, the viewer may not be able to watch the stereoscopic image. There is a problem that you can not watch a clear three-dimensional image. Therefore, in order to solve this problem, as shown in FIGS. 19 and 20, when the stereoscopic image display is in the first mode, the controller 180 moves out of the focus position of the stereoscopic image determined by the first mode. If the image is displayed on the stereoscopic image display, and then the user can reselect the first mode 411 and the second mode 412. Redisplay.

Preferably, each step of the method for controlling the focal position of the stereoscopic image according to the present invention may be displayed on the stereoscopic image display so that the viewer can recognize them sequentially or simultaneously.

15 to 20 are exemplary and the present invention is not limited thereto.
