Content display device, content display method, and recording medium

The present invention relates to a content display device, a content display method, and a recording medium, and more particularly, to a content display device, a content display method, and a recording medium for displaying stereoscopic content.

Conventionally, various techniques have been disclosed for displaying stereoscopic content.
For example, in Patent Document 1 (Japanese Patent Application Laid-Open No. 2007-019666), when a stereoscopic content observer moves his / her body, in order to cope with the horizontal and vertical parallaxes of the observer, Is disclosed, and a technique for changing a stereoscopic image (multi-viewpoint image) to be displayed based on the gaze direction is disclosed. Thereby, even if the observer of the stereoscopic content changes the line-of-sight direction, the observer can naturally observe the stereoscopic content.

JP 2007-019666 A

In recent years, stereoscopic content has been adopted for many contents such as games, and various attempts have been made to reflect the movement of the observer's body when displaying stereoscopic content. Under such circumstances, a display that is not accompanied by a substantial change in display content, such as that the observer can observe naturally, as disclosed in Patent Document 1, is a display that reflects the movement of the observer. Is effective. However, while the technology related to the display of content is rapidly progressing, it is expected that the display content of the content will be substantially changed by the movement of the observer, and the display of the stereoscopic content will be rich in variety.

The present invention has been conceived in view of such circumstances, and its purpose is to change the display content of the three-dimensional content in accordance with the movement of the observer's body.

A content display device according to the present invention includes a housing, a display device, a memory for storing stereoscopic content, a control unit for displaying the stereoscopic content stored in the memory on the display device, A detection unit for detecting the inclination in the first direction. When the detection unit detects a tilt in one direction of the first direction, the control unit changes to increase the pop-out amount of the three-dimensional content, and changes the other direction different from the one direction in the first direction. When the inclination of the direction is detected, a change is made so as to reduce the pop-out amount of the three-dimensional content.

Preferably, the detection unit detects the amount of inclination of the housing in the first direction. Further, the control unit changes the pop-out amount of the three-dimensional content by an amount corresponding to the tilt amount.

Preferably, the control unit changes the pop-out amount of the three-dimensional content on condition that the amount of inclination exceeds a specific amount.

Preferably, the detection unit detects the inclination of the housing in the second direction intersecting with the first direction. In addition, when the detection unit detects the inclination in the second direction, the control unit changes the display target of the stereoscopic content on the display device along the second direction.

The stereoscopic content display method according to the present invention is a stereoscopic content display method executed in a content display device including a housing, a display device, and a memory for storing the stereoscopic content. The display method is changed to increase the pop-up amount of the three-dimensional content when detecting the inclination of the first direction of the housing and the inclination of one direction of the first direction. A step of changing so as to reduce the pop-out amount of the three-dimensional content when an inclination in the other direction different from the one direction in the one direction is detected.

A recording medium according to the present invention stores a computer-readable content display program for causing a computer having a housing, a display device, and a memory for storing stereoscopic content to function as the content display device. It is a medium. The program stored in the recording medium causes the computer to detect the inclination of the first direction of the housing and the amount of projection of the three-dimensional content when the inclination in one direction of the first direction is detected. When the inclination of the other direction different from the one direction of the first direction is detected, the step of changing so as to decrease the pop-out amount of the three-dimensional content is executed.

According to the present invention, the content display device changes the pop-up amount of the stereoscopic content displayed on the display device according to the inclination of the housing in the first direction.

Thereby, the display content of the stereoscopic content displayed on the display device can be substantially changed according to the movement of the body of the observer having the housing.

The process in the mobile phone 100 (for example, the process shown in the flowchart of FIG. 8) is realized by each hardware and software executed by the CPU 110. Such software may be stored in the memory 111 in advance, or may be stored in a recording medium and distributed as a program product. Alternatively, the software may be provided as a program product that can be downloaded by an information provider connected to a network.

Such software is read from the recording medium by using a reading device (not shown), or downloaded by using the communication interface 105 and temporarily stored in the memory 111. The CPU 110 stores the software in the form of an executable program in the memory 111 and then executes the program.

Here, the program includes not only a program that can be directly executed by a processor such as the CPU 110 but also a program in a source program format, a compressed program, and an encrypted program.

<Display of stereoscopic content in content display device>
In the mobile phone 100, the amount of pop-out of the three-dimensional content (object) displayed on the display 101 can be controlled by changing the inclination of the housing 150.

This will be described in more detail with reference to FIGS.
FIG. 5A shows a state in which the user holds the mobile phone 100 by hand and views the stereoscopic display content displayed on the display 101. The pop-out amount of the three-dimensional content displayed on the display 101 at this time is schematically shown in FIG. FIG. 5B schematically shows the degree of pop-out from the display surface 901 of the display 101 when the object 900 of the three-dimensional content is displayed. In FIG. 5B, the user's eyes looking at the display 101 are schematically shown as E.

6A shows a state in which the mobile phone 100 is tilted in the direction of arrow A12 from the state shown in FIG.

The state shown in FIG. 6A is the direction of arrow A12 from the state shown in FIG. 5A, that is, the case where the surface on which the display 101 is provided is the front of the housing 150. This corresponds to a state in which the upper end of the housing 150 is tilted rearward.

When the casing 150 is tilted in this way, the display of the display 101 is controlled so that the amount of the projected three-dimensional content is reduced. This is based on the detection of backward acceleration (acceleration on the + side in the Z-axis direction in FIG. 10) in the Z-axis direction detected by the acceleration sensor 106.

As described above, when the mobile phone 100 is tilted in the direction of the arrow A12 from FIG. 5A, the pop-up amount of the three-dimensional content shown in FIG. 5B is as shown in FIG. Changed as shown. In FIG. 6B, compared to the state shown in FIG. 5B, the amount of protrusion of the object 900 with respect to the display surface 901 is changed in a direction away from the user's eyes E. ing.

7A shows a state in which the mobile phone 100 is tilted in the direction of arrow A11 from the state shown in FIG.

The state shown in FIG. 7A is the same as the state shown in FIG. 5A in the direction of arrow A11, that is, when the surface on which the display 101 is provided is the front of the housing 150. This corresponds to a state in which the upper end of the housing 150 is tilted forward.

When the casing 150 is tilted in this way, the display of the display 101 is controlled so that the amount of the stereoscopic content to be displayed increases. This is based on the fact that forward acceleration (acceleration on the negative side in the Z-axis direction in FIG. 10) is detected in the Z-axis direction detected by the acceleration sensor 106.

As described above, when the mobile phone 100 is tilted in the direction of the arrow A11 from FIG. 5A, the pop-out amount of the three-dimensional content shown in FIG. 5B is as shown in FIG. Changed as shown. In FIG. 7B, compared to the state shown in FIG. 5B, the amount of protrusion of the object 900 with respect to the display surface 901 is changed in a direction approaching the user's eye E. ing.

<Display control of stereoscopic content in content display device>
FIG. 8 is a flowchart of processing (image pop-out amount adjustment processing) performed by the CPU 110 for adjusting the pop-out amount of the stereoscopic content displayed on the display 101.

The CPU 110 executes an image pop-out amount adjustment process in the background when an application for displaying the three-dimensional content on the display 101 is executed, thereby adjusting the pop-out amount of the three-dimensional content.

Referring to FIG. 8, in the image pop-out amount adjustment process, CPU 110 first initializes acceleration sensor 106 in step S10, and advances the process to step S20.

In step S20, the CPU 110 determines whether or not the operation switch 104A is turned on. If it is determined that the operation switch 104A is turned on, the process proceeds to step S30. If it is determined that the operation switch 104A is not turned on, the process returns to step S10.

Here, the operation switch 104A being turned on refers to a state in which the operation switch 104A is pressed and stored in the housing 150 as described with reference to FIG. CPU 110 determines, for example, whether or not operation switch 104A is turned on by detecting the energization state of a predetermined portion or the presence or absence of a potential change in an electric circuit constituting mobile phone 100.

In step S30, the CPU 110 determines whether or not the acceleration sensor 106 has changed in the acceleration detection state in the Z-axis direction (see FIG. 10) after the operation switch 104A is turned on in step S20. If it is determined that the change has occurred, the process proceeds to step S40, and if the change is not detected, the process returns to step S20.

In step S40, the CPU 110 acquires the pop-up amount of the three-dimensional content according to the inclination of the casing 150, and generates image data so that the three-dimensional content displayed on the display 101 at that time is displayed with the pop-out amount. Then, the image data is displayed on the display 101. Here, “the inclination of the casing 150” is determined based on the detected value of the acceleration in the Z-axis direction of the acceleration sensor 106 detected in step S30. The memory 111 stores the pop-up amount of the three-dimensional content in association with the inclination of the housing 150.

The memory 111 is shown in FIG. 6B in association with, for example, the inclination of the direction of the arrow A12 in FIG. 5A (that is, a positive acceleration detected in the Z-axis direction). The pop-out amount that the pop-out amount is smaller than the initial state (FIG. 5B) is stored, and the inclination of the direction of the arrow A11 in FIG. In relation to the negative acceleration detected in the axial direction), the pop-out amount is larger than the initial state (FIG. 5B) as shown in FIG. The pop-out amount is stored.

And CPU110 advances a process to step S50, after updating the display of the display 101 so that the pop-out amount of a solid content may change in step S40.

In step S50, the CPU 110 determines whether or not the operation switch 104A is turned off. If it is determined that the operation switch 104A is not turned off, the process returns to step S30. If it is determined that the operation switch 104A is turned off, the process returns to step S10.

Here, the operation switch 104A being turned off means, for example, a state in which the operation switch 104A has been depressed as shown in FIG. For example, CPU 110 determines whether or not operation switch 104A is turned off by detecting the energization state of a predetermined portion or the presence or absence of a potential change in the electric circuit in mobile phone 100.

In the image pop-out amount adjustment process described above, the tilt of the casing 150 in the Z-axis direction (see FIG. 10) changes during the period when the operation switch 104A is ON (pressed). The pop-out amount of the stereoscopic content to be changed is changed according to the inclination.

It should be noted that such a change in the amount of three-dimensional content pop-up is not limited to a period during which the operation switch 104A is ON (pressed). In other words, when stereoscopic content is displayed on the display 101, the amount of stereoscopic content pop-up changes according to the inclination of the casing 150 in the Z-axis direction without requiring a special operation of pressing the operation switch 104A. May be. In this case, the processes in steps S20 and S50 in FIG. 8 are omitted. Specifically, after the acceleration sensor 106 is initialized in step S10, the state of the acceleration sensor 106 is monitored in step S30, and when it is determined that the state has changed, in step S40, the pop-up corresponding to the change is made. The display of content on the display 101 is updated so as to be displayed in quantity.

In addition, the form of the part that is operated as a condition for changing the pop-out amount of the three-dimensional content is not limited to a button shape like the operation switch 104A. For example, a small hole that can be covered with a human finger is provided on a side surface of the housing 150 where the operation switch 104A is provided, and the small hole is covered with a human finger or the like. Only during a certain period, the pop-up amount of the three-dimensional content may be adjusted according to the inclination of the housing 150. That is, the process of step S20 may be changed so that the small hole is covered with a user's finger or the like and if it is covered, the process proceeds to step S30. In addition, step S50 may be changed so that it is detected whether the small hole is covered with a user's finger or the like, and the process returns to step S10 when it is not covered. The CPU 110 determines whether the small hole is covered with a finger or the like based on, for example, whether light input from the outside of the housing 150 through the small hole can be detected. Specifically, a light receiving element that receives light incident through a small hole is provided inside the housing 150, and the CPU 110 indicates that the small hole indicates that the light received by the light receiving element is less than a predetermined amount. If it is more than the predetermined amount, it is determined that the small hole is not covered with a finger or the like.

In the present embodiment, as described above, the memory 111 stores the pop-up amount of the three-dimensional content in association with each of the positive value acceleration and the negative value acceleration detected in the Z-axis direction. .

It should be noted that the pop-out amount stored in the memory 111 may be stored in multiple stages not only depending on whether it is positive or negative but also corresponding to the magnitude of the acceleration value. As a result, the mobile phone 100 not only tilts the housing 150 but also according to the tilting size (the angle of tilting and / or the magnitude of the force applied to the housing 150 when tilting). The pop-up amount of the stereoscopic content displayed on the display 101 can be controlled.

Furthermore, in the memory 111, the acceleration value and the pop-out amount may be associated by a function or the like. In this case, for example, as shown in FIG. 9, when the inclination (absolute value of detected acceleration) is small, it is preferable that the pop-out amount of the three-dimensional content is not changed.

In FIG. 9, the change amount of the pop-out amount of the three-dimensional content with respect to the inclination of the casing 150 is indicated by a line L1. The amount of change refers to the amount of change in the amount of protrusion from the amount of protrusion displayed at that time (for example, when acceleration is detected in step S30 in FIG. 8). The tilt of the casing refers to the tilt in the Z-axis direction. When the tilt of the casing is zero, the detection output of the acceleration sensor 106 at the time when the operation switch 104A is turned on in step S20. Is the standard.

As described above, when the inclination of the housing 150 is small (when the acceleration value detected by the acceleration sensor 106 is smaller than a specific value), the amount of pop-up of the three-dimensional content is not changed, so that the user can pop out the three-dimensional content. When the amount is not intended to be changed, it is possible to avoid changing the pop-out amount in response to a slight shaking of the housing 150.

<Modification (1)>
In the present embodiment described above, the pop-up amount of the three-dimensional content displayed on the display 101 is the depth direction of the housing 150 as described with reference to FIGS. 5A to 7A. It was changed according to the change of the slope.

In the mobile phone 100, when the casing 150 is tilted in the left-right direction, the display position of the three-dimensional content may be changed according to the tilt in the left-right direction.

That is, in the mobile phone 100, as shown in FIGS. 11A to 11C, when the casing 150 of the mobile phone 100 is tilted in the depth direction, the pop-out amount of the three-dimensional content is changed. In addition, as shown in (D) to (F) of FIG. 11, the display mode of the three-dimensional content is also changed when tilted in the left-right direction.

Changes in the pop-out amount of the three-dimensional content according to the change in the inclination in the depth direction as shown in FIGS. 11A to 11C will be described with reference to FIGS. 5B to 7B. Just as you did.

On the other hand, when the casing 150 is tilted in the left-right direction, that is, from the state shown in FIG. 11E, it is tilted in the direction of the double-headed arrow A20, and FIG. By being in the state shown in F), the display position of the displayed three-dimensional content moves to the left and right.

It will be further described with reference to FIGS. 12, 13A, and 13B that the display position of the stereoscopic content on the display 101 is changed in the left-right direction.

FIG. 12 is a diagram schematically illustrating an example of a display mode of the stereoscopic content on the display 101 when the housing 150 is in the state illustrated in FIG. In FIG. 12, on the display 101, the three-dimensional content 181 is displayed at substantially the center in the left-right direction.

FIG. 13A shows an example of how the three-dimensional content is displayed on the display 101 when the housing 150 is tilted to the left as shown in FIG. 11F from the state shown in FIG. FIG.

In FIG. 13B, the display position of the stereoscopic content shown in FIG. 12 is indicated by a broken line 182 for reference. In FIG. 13B, the three-dimensional content 181 is displayed on the right side of the position shown in FIG.

In this modification, the CPU 110 may change the display position of the stereoscopic content by changing the position (location) of the area used for displaying the stereoscopic content in the display area of the display 101. That is, when an application for displaying stereoscopic content on the display 101 is executed, the CPU 110 adjusts the movement amount of the stereoscopic content in the background according to the amount of inclination of the casing 150 in the left-right direction. Thus, the position (place) of the area used for displaying the stereoscopic content in the display area of the display 101 is changed.

<Modification (2)>
In the present modification, as in the modification (1), when the casing 150 is tilted in the left-right direction, the cross-section to be displayed on the display 101 in the three-dimensional content corresponds to the tilted direction. Changed to position.

The change of the range displayed on the three-dimensional content display 101 according to the tilt of the casing 150 in the front-rear direction will be described with reference to FIGS.

FIG. 18 shows content 1201, which is an example of three-dimensional content. The content 1201 is a part of a larger content 1200 (FIG. 19).

In the present modification, when the acceleration sensor 106 detected in the housing 150 detects the acceleration in the Z-axis direction while the content 1201 that is a part of the content 1200 is displayed on the display 101, The range displayed on the display 101 is changed. More specifically, when the housing 150 is tilted from the state shown in FIG. 5A to the back side as shown in FIG. 6A, the display is displayed on the display 101 as shown in FIG. The content to be changed is changed to the content 1211. FIG. 21 shows the position of the content 1211 in the content 1200.

On the other hand, when the casing 150 is tilted from the state shown in FIG. 5A to the front rear side as shown in FIG. 7A, the contents displayed on the display 101 as shown in FIG. Is changed to content 1212. FIG. 23 shows the position of the content 1212 in the content 1200.

21, the content 1211 is a display range located on the near side of the content 1201 in the content 1200. Also, as shown in FIG. 23, the content 1212 is a display range located on the far side of the content 1201 in the content 1200. 18 to 23, a broken line DL represents a line where the surface represented by the

contents

1201, 1211, and 1212 and the display 101 intersect.

In this modification as well, the amount of change in the display range on the content 1200 may be determined according to the amount of tilt detected by the acceleration sensor 106. Further, when the change amount is determined, it is preferable not to change the display range when the inclination is small to some extent as described with reference to FIG.

Further, as an example of the content 1200 of FIG. 19, a map displayed in three dimensions can be cited. And when the tag is attached | subjected to the said map for every object (building etc.), it displays using a tag according to the housing | casing 150 being inclined to the direction of arrow A12 of (A) of FIG. Control that changes the contents can be considered. Specifically, when an application for displaying content is activated, an image in a range centered on an object corresponding to a tag specified by default is displayed on the display 101. The content includes a plurality of objects, and further includes tags corresponding to each of one or more objects among the plurality of objects. The plurality of tags are stored in association with the arrangement of the objects corresponding to each tag on the map. When tilted in the direction of the arrow A12, the designated tag is changed to a tag arranged at the next position in the direction associated with the direction of the arrow A12 in the content. Then, the display on the display 101 is updated to the one centered on the object corresponding to the changed tag.

Specifically, as shown in FIG. 28, for example, in content 1200, tags are included for object 1281 and object 1282, and the direction corresponding to the direction of arrow A12 in content 1200 is the direction indicated by arrow A120. And It is assumed that a range 1291 centered on the object 1281 is displayed on the display 101. At this time, when the housing 150 is tilted in the direction of the arrow A12 (FIG. 5A), the range displayed on the display 101 is changed from the range 1291 to the range 1292. A range 1292 is a range centered on the object 1282. The arrangement associated with the tag of the object 1282 is positioned next to the arrangement associated with the tag of the object 1281 in the direction of the arrow A120.

When the inclination of the casing 150 in a plurality of directions is detected (for example, as described with reference to FIG. 11, the center of the display range in the double arrow A10 direction map is arranged in the double arrow A81 direction. Among the objects, the object that is currently the center of the display may be changed to a tagged object arranged next to D2. In this case, the arrow in FIG. When it is detected in step S30 that the camera is tilted in the direction of A11, the plane including the start point displayed on the display 101 in the map content 801 is changed to the next object on the D1 side of the double arrow A81. The

<Modification (3)>
In the present embodiment described above, the pop-up amount of the three-dimensional content displayed on the display 101 is the depth direction of the housing 150 as described with reference to FIGS. 5A to 7A. It was changed in response to the change in inclination in the (front-rear direction).

In the mobile phone 100, when the casing 150 is tilted in the left-right direction, the content display mode may be changed according to the tilt in the left-right direction.

On the other hand, when the casing 150 is tilted in the left-right direction, that is, from the state shown in FIG. 11E, it is tilted in the direction of the double-headed arrow A20, and FIG. By being in the state shown in F), the range displayed on the display 101 of the stereoscopic content is changed. The fact that the range of the stereoscopic content displayed on the display 101 is changed in the horizontal direction will be further described with reference to FIGS. 18, 19, and 24 to 27. FIG.

As described above, FIG. 18 shows content 1201 as an example of three-dimensional content. The content 1201 is a part of a larger content 1200 (FIG. 19).

When the content 1201 that is a part of the content 1200 is displayed on the display 101 in the state of FIG. 11E (FIG. 18), the user tilts the housing 150 clockwise as shown in FIG. In the state shown in (D), the content displayed on the display 101 is changed to the content 1202 as shown in FIG. The content 1202 is a display range located on the left side of the content 1201 in the content 1200, as shown in FIG.

When the content 1201 that is a part of the content 1200 is displayed on the display 101 in the state of FIG. 11E (FIG. 18), the user tilts the housing 150 counterclockwise. 11 (F), the content displayed on the display 101 is changed to content 1203 as shown in FIG. As shown in FIG. 27, the content 1203 is a display range located on the right side of the content 1201 in the content 1200.

18, 19, and 24 to 27, a broken line DL represents a line where the surface represented by the contents 1201 to 1203 and the display 101 intersect.

As described above, in this modification, when the casing 150 is tilted in the left-right direction, the range displayed on the display 101 of the stereoscopic content is changed to a position corresponding to the tilted direction.

<Modification (4)>
In the modified example (2) described above, when the casing 150 is tilted in the front-rear direction (FIGS. 11A to 11C), the pop-up amount of the content displayed on the display 101 is changed (FIGS. 5 to 5). 7), and when tilted in the left-right direction (FIGS. 11D to 11F), the cross-section to be displayed on the display 101 in the content is changed so as to move in the left-right direction. Moreover, in the modification (3), when the housing | casing 150 was tilted in the front-back direction, it changed so that the cross section used as the display target in the display 101 in a content might move in the front-back direction.

In this modification, the mobile phone 100 moves the display range of the content in accordance with the inclination of the housing 150 while displaying the stereoscopic content, the mode for changing the pop-up amount, and the content left and right. Operates in move mode.

FIG. 17 shows a flowchart of an example of the image pop-out amount adjustment process executed in the present modification. The image pop-out amount adjustment processing of the present modification corresponds to a process in which steps S60 to S80 are added to the image pop-out amount adjustment processing shown in FIG. The contents will be specifically described below.

Referring to FIG. 17, in the image pop-out amount adjustment process of the present modification, CPU 110 first initializes acceleration sensor 106 in step S10 and advances the process to step S20.

In step S20, the CPU 110 determines whether or not the operation switch 104A is turned on. If it is determined that the operation switch 104A is turned on, the process proceeds to step S30. If it is determined that the operation switch 104A is not turned on, the process proceeds to step S60.

In step S30, the CPU 110 determines whether or not the acceleration sensor 106 has changed in the acceleration detection state in the X-axis direction or the Z-axis direction (see FIG. 10) after the operation switch 104A is turned on in step S20. If it is determined that there is a change, the process proceeds to step S40. If no change is detected, the process returns to step S20.

In step S40, the CPU 110 acquires the pop-up amount of the three-dimensional content according to the inclination of the casing 150, and generates image data so that the three-dimensional content displayed on the display 101 at that time is displayed with the pop-out amount. The display 101 is updated so that the image data is displayed on the display 101, and the process proceeds to step S50.

On the other hand, in step S60, CPU 110 determines whether or not there has been a change in the acceleration detection state in the X-axis direction or the Z-axis direction (see FIG. 10) in acceleration sensor 106 since operation switch 104A was turned on in step S20. If it is determined that there is a change, the process proceeds to step S70. If no change is detected, the process returns to step S20.

In step S70, the CPU 110 updates the display on the display 101 to move the cross section in the manner described with reference to FIGS. 12, 13A, and 13B according to the inclination of the casing 150, and then proceeds to step S80. Proceed with the process.

In step S80, the CPU 110 determines whether or not the operation switch 104A is turned on. If it is determined that the operation switch 104A is turned on, the process returns to step S10, and if it is determined that it is not turned on, the process returns to step S60.

As described above, in this modification, the content pop-out amount is controlled according to the inclination of the housing 150 when the operation switch 104 is turned on, and the housing 150 when the operation switch 104 is not turned on. The position of the cross section to be displayed in the content is controlled according to the inclination of the content. Note that when the operation switch 104 is turned on, the position of the cross section to be displayed in the content is controlled according to the tilt of the case 150, and when the operation switch 104 is not turned on, The amount of content jumping out may be controlled according to the inclination.

<Modification (5)>
In the present embodiment described above, the pop-out amount of the three-dimensional content is changed for the entire display content according to the inclination of the housing 150.

In this modification, the pop-up amount in the display may be determined for each object included in the content.

FIG. 14 is a flowchart of a subroutine for determining the pop-out amount in step S40 (see FIG. 8).

Referring to FIG. 14, in the present modification, CPU 110 obtains the type of the Nth object included in the stereoscopic content in step S41. The object type is acquired based on, for example, the file name of the object.

Next, in step S42, the CPU 110 acquires a jump amount change mode according to the type of object, and advances the process to step S43. In the memory 111, depending on the type of object, for example, when the casing 150 is tilted to one side (+ side in the Z-axis direction), the pop-out amount is increased or the pop-out amount is decreased. Is stored. In step 42, the change type of the object type acquired in step S41 is acquired.

In step S43, the CPU 110 obtains the pop-out amount corresponding to the amount of change in the inclination of the casing 150, and advances the process to step S44.

The memory 111 stores a pop-out amount corresponding to the amount of change in inclination. The CPU 110 acquires the amount of change in the tilt of the housing 150 based on the detection output of the acceleration sensor 106. Then, the pop-out amount corresponding to the acquired amount of change in inclination is acquired based on the above-described stored contents.

In step S44, the CPU 110 determines whether or not the pop-out amount has been determined in step S43 for all the objects included in the stereoscopic content that is the display target of the display 101. Each object is displayed on the display 101 by the amount, and the process returns to FIG. On the other hand, if it is determined that the pop-out amounts of all objects have not yet been determined, N is incremented by 1 in step S45, and the process returns to step S41.

In this modification, N is initialized to 1 at the start of the process of FIG.
In the modification described above, when the casing 150 is tilted in a certain direction, a part of the objects included in the three-dimensional content has an amount of popping up, and other objects have a small amount of popping out. The display is updated.

Thereby, for example, when a plurality of characters are included in the stereoscopic content, when the casing 150 is tilted in a certain direction, the pop-out amount is small for the remaining characters so that the pop-out amount is increased for some characters. Thus, the display on the display 101 is changed. Note that when the casing 150 is tilted in the opposite direction, the pop-out amount of each character may be changed in the opposite direction.

As another example, when text and characters are included in the three-dimensional content, when the casing 150 is tilted in a certain direction, the pop-out amount is increased for the character, and the pop-out amount is decreased for the text. The display on the display 101 is changed.

Note that when the casing 150 is tilted in the opposite direction, the pop-out amounts of the character and the text may be changed in the opposite directions. Further, before the casing 150 is tilted, in the content, the text and the character are displayed so as to be positioned on the same plane, and when the casing 150 is tilted, as described above, the text and the character (or a plurality of types) are displayed. The pop-out amount of each object may be controlled so that the pop-out amount of the character (2) is changed.

Also, even with one character, the change mode of the pop-out amount may be adjusted for each portion. That is, for example, when the housing 150 is tilted in the direction of the arrow A11 in FIG. 5A, the upper body of the character has a larger amount of protrusion, and the lower body of the character has a smaller amount of protrusion. In addition, the display on the display 101 may be changed.

<Modification (6)>
In the present embodiment described above, the inclination of the housing 150 is detected by the acceleration sensor 106, but the detection of the inclination of the housing in the content display device of the present invention is not limited to this. For example, as shown in FIG. 15, the mobile phone 100 includes a camera 106 A instead of the acceleration sensor 106, and can detect the tilt of the housing 150 by processing an image captured by the camera 106 A. .

FIG. 16 is a functional block diagram of the mobile phone 100 of the present modification.
Referring to FIG. 16, in the present modification, an image processing unit 196 is provided instead of the posture detection unit 194 (see FIG. 4).

The image processing unit 196 detects a tilt of the housing 150 by processing a plurality of images taken at different timings by the camera 106A, and is realized by the CPU 110 executing a predetermined program, for example. This circuit may be realized.

For example, the image processing unit 196 detects two overlapping timings when two images are arranged in space by detecting an overlapping portion by using a normalized cross-correlation method in images taken at two different timings. The direction of movement of the camera 106A is calculated. In the present modification, the calculated movement direction is the movement direction of the housing 150.

In the present modification, any other calculation method can be employed as long as the direction of movement of the housing 150 is calculated based on the captured image.

<Other variations>
In the above-described embodiment and its modifications, the display 101 which is an example of the display device is provided integrally with the housing 150, but the present invention is not limited to this. The pop-out amount of the three-dimensional content on the display 101 may be changed according to the inclination of the casing 150 that is configured separately from the display 101.

The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
