5A, when the mobile terminal 100 is positioned at the same point so that the distance between the left eye image and the right eye image is 0, the degree of protrusion of the composite image 503 (0) is set to 0 so that the two- The same effect can be obtained.

The distance between the right eye image 501 (d1) and the left eye image 502 (d1) is D1, and the intersection of the right eye line and the left eye line is shifted from the point where the projection degree = 0 to d1 , The composite image {503 (d1)} can be projected and displayed by d1.

The mobile terminal 100 also determines that the distance between the right eye image 501 (d2) and the left eye image 502 (d2) is D2 (> D1) and the intersection of the right eye line and the left eye line is the projection degree = If it is located at d2 (> d1) from the point, the composite image {503 (d2)} can be projected and displayed by d2.

That is, when it is assumed that the intersection of the right-eye line and the left-eye line is located before the point of the projection degree = 0, the larger the distance between the right-eye image and the left-eye image is, the more the composite image can be displayed.

Fig. 5b shows a three-dimensional recessed display of the composite image.

5B, when the mobile terminal 100 is positioned at the same position so that the distance between the left eye image and the right eye image is 0, the degree of depression of the composite image 503 (0) is set to 0, The same effect can be obtained.

The distance between the right eye image 501 (-d3) and the left eye image 502 (-d3) becomes D3 and the intersection of the right eye line and the left eye line becomes -d3, it is possible to display the composite image {503 (-d3)} by the depth-d3.

In addition, the mobile terminal 100 determines that the distance between the right eye image 501 (-d4) and the left eye image 502 (-d4) is D4 (> D3) and the intersection of the right- The composite image 503 (-d4) can be displayed at a depth of -d4 when it is located at -d4 (<-d3) from the zero point.

That is, when it is presumed that the intersection of the right-eye line and the left-eye line is located behind the point where the degree of depression is equal to zero, the larger the distance between the right-eye image and the left-eye image is, the more the composite image can be displayed.

4, the mobile terminal 100 receives the switching instruction operation from any one of the two-dimensional display and the three-dimensional display through the user input unit 130 during the display step S410 ( S420).

More specifically, when the current display method is a two-dimensional display, the mobile terminal 100 can receive a switching command operation from a two-dimensional display to a three-dimensional depression display or a three-dimensional projection display. Conversely, when the current display method is a three-dimensional display (including a three-dimensional projection or a dimple display), the mobile terminal 100 can receive a switching instruction operation from a three-dimensional display to a two-dimensional display.

Furthermore, the mobile terminal 100 can display a three-dimensional protruding display (or three-dimensional protruding display) in a three-dimensional recessed display (or a three-dimensional protruding display) when the current display method is a three- Display).

The mobile terminal 100 may receive a switching command operation when a menu item or a key corresponding to the switching method of the display method (or when the key area_touch screen is included) is selected by the user.

Alternatively, when the display unit 151 includes a touch screen, the mobile terminal 100 may receive a touch operation (or a touch action) corresponding to the switching instruction as a switching instruction operation.

For example, in the case of the current two-dimensional display, the touch operation corresponding to the switching instruction from the two-dimensional display to the three-dimensional depression display and the three-dimensional projection display may have different touch patterns. Specifically, the touch operation corresponding to the instruction to switch to the three-dimensional recessed display includes a touch drag operation in the right direction from one point corresponding to the object to be displayed in three dimensions, The corresponding touch operation may include a left-to-right touch drag operation at a point corresponding to an object to be three-dimensionally displayed.

In addition, the mobile terminal 100 can receive the tilting motion of a certain angle in a predetermined direction as a switching command operation. At this time, the mobile terminal 100 can detect the direction and angle of the tilting motion as well as whether the tilting motion is generated or not by using the motion detection sensor (not shown) included in the user input unit 130 or the sensing unit 140 have.

More specifically, the mobile terminal 100 can receive a switching command operation when a tilting operation of a certain angle or more is detected in a clockwise or counterclockwise direction.

For example, when the mobile terminal 100 detects a tilting motion of 10 degrees or more in a clockwise direction in a two-dimensional display state, the mobile terminal 100 can receive a switching command operation to the three-dimensional display, When returned, the three-dimensional display switched by the input switching instruction operation can be maintained.

Alternatively, when the mobile terminal 100 is currently performing two-dimensional display, when the tilting operation is detected over a predetermined angle in the clockwise direction, the mobile terminal 100 receives the switching command operation to the three-dimensional protruding display, It is possible to receive the switching command operation to the three-dimensional recessed display. Furthermore, the mobile terminal 100 can maintain the three-dimensional projection display or the three-dimensional projection display switched by the input switching instruction operation even when the mobile terminal 100 returns to the state before the tilting operation is sensed.

Alternatively, when the mobile terminal 100 is performing a two-dimensional display (or a three-dimensional display) in the current portrait view (or landscape view) direction, an iterative movement within a certain angle range in the clockwise or counterclockwise direction is detected When converted into a horizontal view (or vertical view) direction, a switching instruction operation to a three-dimensional display (or a two-dimensional display) can be input.

In addition, the mobile terminal 100 may receive the shaking motion of the mobile terminal 100 as a switching command operation.

For example, the mobile terminal 100 may receive a switching command operation when a predetermined number of shaking operations are input. In addition, when the shaking motion is inputted once, the mobile terminal 100 performs a switching instruction operation to the three-dimensional projection display when the shaking operation is inputted once, and a switching instruction operation to the three-dimensional projection display when the shaking operation is inputted twice Input can be received.

The mobile terminal 100 performs the switching operation between the two-dimensional display and the three-dimensional display upon receiving the switching command operation in the input step S420 under the control of the controller 180 at step S430.

For example, if the current display is a two-dimensional display, the switching operation from the two-dimensional display to the three-dimensional display is performed, and if the current display is a three-dimensional display, the switching operation from the three-dimensional display to the two-dimensional display can be performed.

Also, in the case of the current two-dimensional display, the switching operation from the two-dimensional display to the three-dimensional depression display or the three-dimensional projection display is performed depending on whether the three-dimensional display scheme indicated by the input switching instruction operation is a depressed display or an extrude display Can be performed.

According to the control of the control unit 180, the mobile terminal 100 displays at least one intermediate image in order to gradually display or display any of at least one object included in the displayed image during the switching operation (S440). Here, the display step S440 may be performed through the display unit 151. [

Here, the at least one intermediate image may include at least one object included in the image to be displayed in the display step S410, and may have a degree of projection or depression in order to the object to be subjected to the switching operation .

The mobile terminal 100 may perform a switching operation for a specific object selected by the user among the displayed at least one object or may perform a switching operation for all of the displayed at least one object. In particular, in the former case, the user input unit 130 may receive a selection operation for a specific object from the user before performing the switching operation. Furthermore, the mobile terminal 100 may perform a switching operation on the displayed image itself.

According to the first case, when performing the switching operation from the two-dimensional display to the three-dimensional protruding display under the control of the control unit 180, the mobile terminal 100 performs a switching operation One intermediate image can be sequentially displayed.

According to the second case, when performing the switching operation from the two-dimensional display to the three-dimensional depression display, under the control of the control unit 180, the mobile terminal 100 performs a switching operation One intermediate image can be sequentially displayed.

Furthermore, in the first or second case, the controller 180 can set the degree of protrusion or the degree of depression of the object to be converted to be smaller than the degree of protrusion or depression of the object to be displayed in three dimensions upon completion of the conversion process have.

At this time, the degree of projection or depression of the object to be converted included in the specific image among the at least one intermediate image may be set to be larger than the degree of projection or depression of the object to be displayed in three dimensions upon completion of the conversion process. For example, if the degree of protrusion of the object to be switched is limited to the switching operation to the three-dimensional protruding display, the first distance in the last (or previous) intermediate image, and the second distance Is smaller than a predetermined value), it can be displayed elastically.

According to the third case, when performing the switching operation from the three-dimensional protruding display to the two-dimensional display under the control of the control unit 180, the mobile terminal 100 sequentially displays the two- At least one intermediate image can be sequentially displayed.

According to the fourth case, when performing the switching operation from the three-dimensional depression display to the two-dimensional display under the control of the control unit 180, the mobile terminal 100 performs the switching operation in the order of decreasing the degree of depression of the switching object At least one intermediate image can be sequentially displayed.

Furthermore, in the third or fourth case, the controller 180 may set the degree of protrusion or the degree of depression of the object to be switched to be larger than the degree of protrusion or the degree of depression of the object to be displayed in two dimensions upon completion of the switching process have.

At this time, the degree of projection or depression of the object to be converted included in the specific image among the at least one intermediate image may be set to be smaller than the degree of projection or depression of the object to be displayed two-dimensionally upon completion of the conversion process. For example, the degree of protrusion or depression of the object to be switched can be elastically displayed as the depression display or the protrusion display in the last (or previous) intermediate image is displayed in two dimensions.

As described above, the mobile terminal 100 does not display the object to be converted having a certain degree of protrusion or specific degree of depression only at the time of completion of the switching operation, but rather displays the degree of protrusion or the degree of depression of the object to be converted It is possible to display a process in which the object to be converted gradually protrudes or sinks by sequentially displaying at least one intermediate image which is different from each other.

With respect to the display step S440, it will be described in detail below with reference to the accompanying drawings.

Figures 6 to 8C are diagrams illustrating intermediate image display in response to an input of a switch command operation. 6 and 7, it is assumed that the vertical view has an inclination angle of 0 to 10 degrees and the horizontal view has an inclination angle of 80 to 90 degrees (reference_vertical view).

6, when the mobile terminal 100 is tilted in the clockwise direction, the mobile terminal 100 is rotated in the vertical direction by a tilting angle of 10 degrees or more and less than 30 degrees At least one intermediate image can be sequentially displayed within the range (b).

For example, the display time of the intermediate image may be determined according to the tilt angle. Specifically, the first intermediate image may be displayed at 15 degrees, the second intermediate image at 20 degrees, and the third intermediate image at 25 degrees, respectively.

The mobile terminal 100 can complete the switching operation from the three-dimensional display to the two-dimensional display when the mobile terminal 100 is further inclined so as to have an inclination angle of 30 degrees or more and less than 60 degrees in (b) (C).

In addition, the mobile terminal 100 may sequentially display at least one intermediate image when the mobile terminal 100 is further inclined so as to have an inclination angle of 60 degrees or more and less than 80 degrees in (c) .

When the horizontal view is set to have an inclination angle of 80 degrees or more in (b), the mobile terminal 100 completes the switching operation from the two-dimensional display to the three-dimensional display and performs two-dimensional display in the horizontal view (D) It can be done.

7, when the mobile terminal 100 is tilted in the clockwise direction (until before the switch to the landscape view), the mobile terminal 100 performs a three-dimensional display in the vertical view One intermediate image can be displayed sequentially (b).

For example, the display time of the intermediate image may be determined according to the tilt angle. Specifically, the first intermediate image at 15 degrees, the second intermediate image at 30 degrees, the third intermediate image at 45 degrees, the fourth intermediate image at 60 degrees, and the fifth intermediate image at 75 degrees, respectively .

When the horizontal view is set to have an inclination angle of 80 degrees or more in (b), the mobile terminal 100 completes the switching operation from the three-dimensional display to the two-dimensional display and performs two-dimensional display in the horizontal view (D) It can be done.

6 and 7, the mobile terminal 100 may be tilted counterclockwise. When tilted in a counterclockwise direction, the angle of the vertical view is 0 to -10 degrees, and the angle of the horizontal view is -80 degrees / RTI &gt; to -90 degrees.

FIGS. 8A to 8C show a process of performing a three-dimensional projection display or a three-dimensional projection display along the tilting direction. 8A to 8C, the horizontal view has an inclination angle of -10 to 10 degrees, and the vertical view shows an inclination angle of 80 to 90 degrees or a range of -80 to -90 degrees (Standard_horizontal view).

8A, the mobile terminal 100 can perform two-dimensional display in the landscape view.

8A, when the mobile terminal 100 is tilted counterclockwise in FIG. 8A (①), the mobile terminal 100 displays at least one intermediate image (from the tilted angle -10 degrees to -80 degrees) (A), when the conversion into the portrait view is completed (or from the tilting angle of -80 degrees to -90 degrees), the switching operation from the two-dimensional display to the three-dimensional depression display is completed and the three-dimensional depression display is performed (B).

At this time, it is possible to display a process in which the specific object or the image itself gradually sinks using at least one intermediate image.

Alternatively, according to FIG. 8C, when the mobile terminal 100 is tilted in the clockwise direction in FIG. 8A ((2)), the mobile terminal 100 displays at least one intermediate image (up to a tilt angle of 10 to 80 degrees) (A) completing the switching operation from the two-dimensional display to the three-dimensional projection display and performing the three-dimensional projection display when the switching to the portrait view is completed (or tilting angle 80 degrees to 90 degrees) b).

At this time, it is possible to display a process in which the specific object or the image itself gradually protrudes using at least one intermediate image.

6 to 8C, the three-dimensional display and the two-dimensional display can be changed and applied to each other. Further, the specific angles referred to in Figs. 6 to 8C are merely one embodiment, and other numerical values may be applied. In addition, it is also possible to perform a switching operation when receiving a tilting operation while a specific key (or a button) provided in the terminal shown in Figs. 6 to 8C is selected, or when a tilting operation is inputted after a specific key is selected.

Hereinafter, a process in which a plurality of objects (hereinafter referred to as object icons 1 to 4) of a switching object is gradually protruded or depressed while a switching operation is performed between the three-dimensional display and the two-dimensional display will be described.

For convenience of explanation, the object to be switched is limited to the object icon 1. Of course, the object to be switched may be the displayed image itself or all objects included in the image.

9A and 9B are first diagrams illustrating a process of successively projecting and displaying object icons. 9A and 9B show a case where the degree of increase of the degree of protrusion with time is constant (constant in slope or constant in rate of protrusion).

For convenience of explanation, it is assumed that a total of two intermediate images can be displayed, and the first intermediate image at the time t / 3 of the switching operation time t can be displayed at a time of 2t / 3 . Of course, the number of intermediate images and the display time can be set variously.

The mobile terminal 100 can display the first intermediate image in which the object icon 1 is protruded by (901) a1 three-dimensionally at the time point t / 3 after the start of the switching operation (b) The second intermediate image in which the object icon 1 901 is protruded by 2a1 can be displayed in three dimensions (c).

The mobile terminal 100 can display an image of the object icon 1 901 projected by the angle 3a1 in three dimensions at a time point t when the switching operation is completed (d).

Referring to FIG. 9B, a process of performing the switching operation shown in FIG. 9A will be described below with reference to a graph.

9B, when the switching operation to the three-dimensional protruding display is performed during the execution of the two-dimensional display, the object icon 1 901 is projected and displayed by a1 at t / 3 (= t1) The object icon 1 901 is projected and displayed by 2a1 at the time t = 3 and the object icon 901 is projected and displayed by 3a1 at the completion time t = t completion of the conversion process. That is, it can be seen that the degree of protrusion of the object icon 1 (901), which is the switching object, with respect to the switching time of the switching operation has a constant slope.

9A and 9B, a process of switching from a three-dimensional protruding display to a two-dimensional display will be described below. For convenience of explanation, it is assumed that the object icon 1 in the three-dimensional protruding display is projected and displayed by 3a1.

The mobile terminal 100 can three-dimensionally display the first intermediate image protruded by the object icon 1 (901) by 2a1 (a1 reduction from the three-dimensional protrusion display) at the time t / 3 after the start of the switching operation (Refer to FIG. 9A (c)), the object icon 1 901 can be displayed three-dimensionally at a 2t / 3 time point by projecting a second intermediate image projected by a1 (2a1 reduction from the three-dimensional projection display) 9a (b)].

The mobile terminal 100 can display an image including the object icon 1 901 (protrusion degree = 0) in two dimensions at a time t when the switching operation is completed (Fig. 9 ) Reference}.

9B, when the switching operation to the two-dimensional display is performed during the three-dimensional protrusion display, the object icon 1 (901) is protruded and displayed by 2a1 at t / 3 (= t1) The object icon 1 901 is projected and displayed as a1 at the time point t3 and the object icon 1 901 is projected at the completion point t of the conversion process.

FIGS. 10A and 10B are first diagrams illustrating a process of sequentially displaying an object icon sequentially. FIG. FIGS. 10A and 10B show a case where the degree of increase of the depression degree with time is constant (the slope constant or the depression rate constant).

For convenience of explanation, it is assumed that a total of two intermediate images can be displayed, and the first intermediate image at the time t / 3 of the switching operation time t can be displayed at a time of 2t / 3 . Of course, the number of intermediate images and the display time can be set variously.

10A, the mobile terminal 100 displays the image including the object icons 1 to 4 (901 to 904) two-dimensionally, and switches the object icon 1 (901) to the three- (A).

At this time, the switching operation may be performed when a key, a key region, or a menu item corresponding to the switching operation is selected by the user.

The mobile terminal 100 can display the first intermediate image in which the object icon 1 901 is recessed by -a1 in three dimensions at the time point t / 3 after the start of the switching operation, (b) The second intermediate image in which the object icon 1 901 is recessed by -2a1 can be displayed in three dimensions (c).

The mobile terminal 100 can display an image in which the object icon 1 901 is recessed by -3a1 at a time t when the switching operation is completed (d).

Referring to FIG. 10B, a process of performing the switching operation shown in FIG. 10A will be described below as a graph.

10B, when the switching operation to the three-dimensional depression display is performed during the execution of the two-dimensional display, the object icon 1 (901) is depressed by -a1 at t / 3 (= t1) The object icon 1 901 is depressed by -2a1 at time t3 / t2 and the object icon 901 is displayed at the time of completion of the switching process t = t3. That is, it can be seen that the degree of depression of the object icon 1, which is the switching object, with respect to the switching time of the switching operation has a constant slope.

10A and 10B, a process of switching from a three-dimensional recessed display to a two-dimensional display will be described. For convenience of explanation, it is assumed that the object icon 1 in the three-dimensional recessed display is displayed by the depressed amount by -3a1.

The mobile terminal 100 displays the first intermediate image which is recessed by the object icon 1 (901) at the time t / 3 after the start of the switching operation by -2a1 (-a1 reduction from the three-dimensional recess display) (Refer to FIG. 10A (c)), the second intermediate image, which is recessed by the object icon 1 (901) at the 2t / 3 time point by -a1 (-2a1 decrease from the three-dimensional recess display) (See FIG. 10A (b)).

The mobile terminal 100 can display an image including the object icon 1 901 (degree of depression = 0) in two dimensions at a time t when the switching operation is completed (FIG. 10A ) Reference}.

10B, when the switching operation to the two-dimensional display is performed during the execution of the three-dimensional depression display, the object icon 1 (901) is depressed by -2a1 at t / 3 (= t1) The object icon 1 901 is depressed as much as -a1 at the point of time t1 / 3 (= t2) and the object icon 1 901 is not projected at the completion time (t = t completion) have.

FIGS. 11A through 11D are second diagrams illustrating a process of successively projecting and displaying object icons. FIG. 11A to 11D show a case in which the degree of increase in the degree of protrusion with time gradually increases (tilted or protruding velocity increases).

For convenience of explanation, a total of four intermediate images can be displayed, and a second intermediate image at a time point t / 5 of the switching operation, a second intermediate image at a time point tt / 5 of the first intermediate image, It is assumed that the third intermediate image can be displayed at the 4t / 5 time point, respectively. Of course, the number of intermediate images and the display time can be set variously.

11A to 11C, the mobile terminal 100 displays two-dimensionally an image including object icons 1 to 4 (901 to 904), and displays three-dimensional protruding display Can be performed.

At this time, the switching operation may be performed when a key, a key region, or a menu item corresponding to the switching operation is selected by the user.

The mobile terminal 100 can display the first intermediate image in which the object icon 1 is protruded by (901) b1 at the time point t / 5 after the start of the switching operation in three dimensions (Fig. 11 (b) The object icon 1 can be displayed three-dimensionally at the time point of / 5 when the object icon 1 (901) is projected by b2 (Fig. 11 (b) The first intermediate image projected by the object icon 901 b3 can be displayed in three dimensions (Fig. 11B (b)), and the second intermediate image, in which the object icon 1 901 is projected by b4 at the 4t / (Fig. 11C (a)).

At this time, b2-b1 (the degree of increase in the degree of projection at t / 5 to 2t / 5) is larger than b1 (the degree of increase in the degree of projection at 0 to t / 5) / 5), and b3-b2 (degree of increase in the degree of protrusion at 2t / 5 to 3t / 5) is larger than b2-b1 (i.e., the slope at 3t / 5 is higher than the slope at 2t / And b4-b3 (degree of increase in the degree of protrusion at 3t / 5 to 4t / 5) is larger than b3-b2.

The mobile terminal 100 can display an image of the object icon 1 (901) protruded by b5 in three dimensions at the time (t) when the switching operation is completed (Fig. 11 (b)).

At this time, b5 may be a degree of protrusion smaller than b4. In other words, the object icon 1 (901) can complete the switching operation with the degree of protrusion reduced to some extent after reaching the maximum protrusion degree before the completion of the switching operation. Therefore, the protruding display operation for the object icon 901 can be displayed elastically as it is at the completion time. Of course, in some cases, the elastic projection display operation may not be performed.

Referring to FIG. 11D, a process of performing the switching operation shown in FIGS. 11A to 11C will be described as follows.

11 (d), the object icon 1 (901) is projected and displayed by b1 at t / 5 (= t1), and the 2t / The object icon 1 901 is projected and displayed by b2 (b2-b1> b1) at time t5 (= t2) and object icon 1 901 is displayed at b3 (b3-b2> b2 the object icon 1 901 is projected and displayed by b4 (b4-b3> b3-b2) at the time of 4t / 5 (= t4) The object icon 1 901 may be displayed by b5 (<b4).

In other words, it can be seen that the degree of protrusion of the object icon 1 (901), which is the object to be switched with respect to the switching time of the switching operation, gradually increases with time. The protrusion degree b4 of the object icon 1 901 displayed last is larger than the protrusion degree b5 of the object icon 1 901 displayed at the completion of the switching operation so that the object icon 1 is elastically It can be seen that the protrusion is displayed.

11A to 11D, a process of switching from a three-dimensional protrusion display to a two-dimensional display will be described below. For convenience of explanation, it is assumed that the object icon 1 is projected and displayed by b5 in the three-dimensional protrusion display.

The mobile terminal 100 can display the first intermediate image in which the object icon 1 901 is protruded by b4 at t / 5 (= t1) after the start of the switching operation in three dimensions (Fig. 11c (b (See FIG. 11B), 3t / 5 (= t2), the second intermediate image in which the object icon 1 901 is protruded by b3 at the time of 2t / 5 (= t2) the third intermediate image in which the object icon 1 901 is protruded by b2 at the time t3 can be displayed in three dimensions (refer to FIG. 11 (b)) and 4t / 5 (= t4) ) Can be displayed in three dimensions (see Fig. 11A (b)).

Then, the mobile terminal 100 can display the image including the object icon 1 (901) (protrusion degree = 0) two-dimensionally at the time when the switching operation is completed (t = t completion) 11a (a).

A graph showing the degree of protrusion with respect to the progress time of the switching operation corresponding to the switching from the three-dimensional projection display to the two-dimensional display is shown in FIG. 11 (b).

FIGS. 12A to 12D are second diagrams illustrating a process of sequentially displaying object icons sequentially. FIG. 12A to 12D show a case in which the degree of increase in the degree of depression with time increases (the gradient increases or the depression rate increases).

For convenience of explanation, a total of four intermediate images can be displayed, and a second intermediate image at a time point t / 5 of the switching operation, a second intermediate image at a time point tt / 5 of the first intermediate image, It is assumed that the third intermediate image can be displayed at the 4t / 5 time point, respectively. Of course, the number of intermediate images and the display time can be set variously.

12A to 12C, the mobile terminal 100 displays the image including the object icons 1 to 4 (901 to 904) two-dimensionally and the object icon 1 (901) Can be performed.

At this time, the switching operation may be performed when a key, a key region, or a menu item corresponding to the switching operation is selected by the user.

The mobile terminal 100 can display the first intermediate image in which the object icon 1 is recessed by (901) -b1 at the time point t / 5 after the start of the switching operation in three dimensions (Fig. 12 (b) The second intermediate image in which the object icon 1 901 is protruded by -b2 at the time of 2t / 5 can be displayed in three dimensions (Fig. 12b (a)), and at the time of 3t / The first intermediate image protruded by 901-b3 can be displayed in three dimensions (Fig. 12 (b)), and the object icon 1 901 protruded by -b4 at the 4t / The image can be displayed in three dimensions (Fig. 12 (a)).

(The degree of increase in the degree of depression at t / 5 to 2t / 5) is larger than | -b1 | (degree of increase in the degree of depression at 0 to t / 5) , The slope at 2t / 5 is more urgent than the slope at t / 5) and | -b3 - (- b2) | (the degree of increase in depression degree at 2t / 5 ~ 3t / 5) b3) | (degree of increase in depression degree at 3t / 5 to 4t / 5) is larger than the slope at 3t / 5 (i.e., the slope at 3t / 5 is more urgent than the slope at 2t / Is larger than | -b3 - (- b2) |.

Then, the mobile terminal 100 can display an image in which the object icon 1 901 is recessed by -b5 at a time point t when the switching operation is completed (Fig. 12C (b)).

At this time, | -b5 | may be a degree of depression smaller than | -b4 |. In other words, the object icon 1 (901) can complete the switching operation in a state in which the degree of depression is reduced to some degree after reaching the highest depression degree before the completion of the switching operation. Therefore, the depression display operation for the object icon 901 can be displayed elastically as it is at the completion time. Of course, the elastic depression display operation may not be performed in some cases.

Referring to FIG. 12D, a process of performing the switching operation shown in FIGS. 12A to 12C will be described below with reference to a graph.

12A, when the switching operation to the three-dimensional depression display is performed during the two-dimensional display, the object icon 1 901 is depressed by -b1 at t / 5 (= t1) The object icon 1 901 is displayed at the time of / 5 (= t2) by -b2 (| -b2- (- b1) |> | -b1 | The object icon 1 901 is displayed at the time of 4t / 5 (= t4) by b3 (| -b3 - (- b2) |> | -b2 - (- b1) -b4 - (- b3) |> | -b3 - (- b2) |) and the object icon 1 901 becomes -b5 (| -b5 |) at the completion point &Lt; | -b4 |).

That is, it can be seen that the inclination of the object icon 1 (901), which is the switching object with respect to the switching time of the switching operation, gradually increases with time. Also, the degree of depression (| -b4 |) of the object icon 1 901 displayed last is larger than the degree of depression (| -b5 |) of the object icon 1 901 displayed at the completion of the switching operation, Icon 1 may appear to be elastically recessed displayed.

12A to 12D, a process of switching from a three-dimensional recessed display to a two-dimensional display will be described below. For convenience of explanation, it is assumed that the object icon 1 is displayed as -b5 in the three-dimensional recessed display.

The mobile terminal 100 can three-dimensionally display the first intermediate image in which the object icon 1 901 is recessed by -b4 at t / 5 (= t1) after the start of the switching operation (Fig. 12C the second intermediate image in which the object icon 1 901 is recessed by -b3 at the time of 2t / 5 (= t2) can be displayed three-dimensionally (see FIG. 12b (b) (refer to FIG. 12 (b)) and 4t / 5 (= t4), the third intermediate image in which the object icon 1 901 is recessed by -b2 at the time t3 (= t3) 1 901 can be displayed three-dimensionally as a second intermediate image recessed by -b1 (see FIG. 12 (b)).

Then, the mobile terminal 100 can display an image including the object icon 1 901 (degree of depression = 0) in two dimensions at the time when the switching operation is completed (t = t completion) 12a (a).

A graph showing the depression degree with respect to the progress time of the switching operation corresponding to the switching from the three-dimensional depression display to the two-dimensional display is shown in FIG. 12 (b).

Although the intermediate image display process has been described herein with respect to the switching operation between the two-dimensional display and the three-dimensional display, the above-described intermediate image display process can also be applied to the switching operation between the second three- have. At this time, the degree of image projection or degree of image depression of each of the first and second three-dimensional displays must be different.

Further, the two-dimensional display referred to in this specification includes a state in which the left and right images are overlapped and displayed in the three-dimensional display (a state in which the three-dimensional display function is activated), or a state in which the three- State. That is, the two-dimensional display emphasizes that the image appears to be displayed two-dimensionally externally.

According to the present invention, the mobile terminal 100 receives the selection operation of the number of intermediate images to be displayed and the degree of projection (or the degree of depression) of each intermediate image through the user input unit 130 from the user have. Accordingly, the controller 180 can set the number of intermediate images and the degree of protrusion (or degree of depression) corresponding to the input selection operation.

According to an embodiment of the present invention, the image display control method of the mobile terminal described above can be implemented as a code that can be read by a processor on a medium on which the program is recorded. Examples of the medium that can be read by the processor include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, etc., and may be implemented in the form of a carrier wave (e.g., transmission over the Internet) .

The above-described mobile terminal and its image display control method are not limited to the configuration and method of the above-described embodiments, but the embodiments can be applied to all or some of the embodiments May be selectively combined.
