Description

  The present invention relates to a terminal device and a program for displaying display information in 3D on a display unit.

  Conventionally, there are various techniques for displaying 3D (three-dimensional) display information such as images (still images, moving images), text, menus, etc. on a flat display unit. For example, 2D (two-dimensional) display information There is a technology to make an object appear three-dimensionally by applying a visual effect that makes the object appear three-dimensional. The technique using polygons is an example of this technique. There is also a technology that uses parallax of the user's right eye and left eye. That is, display information for the right eye and display information for the left eye that are slightly shifted from each other are prepared, and the two display information are displayed at the same time. At this time, the display information for the right eye is visible to the right eye but not to the left eye. In addition, the display information for the left eye is a technique that makes the display information appear three-dimensional by disposing a parallax barrier that blocks the light path so that the display information can be seen by the left eye but not the right eye. .

  In any of the 3D display technologies described above, there is a parameter called 3D depth indicating the depth of 3D or the degree of popping, and the larger the 3D depth, the deeper the display information will appear to the user or the more popping out. . On the other hand, as the 3D depth is smaller, the display information appears shallower or does not appear to protrude so much, and when the 3D depth is zero, it appears as 2D (that is, 2D display).

By the way, when 3D display information of a predetermined 3D depth is displayed on the display unit (may include 2D display with a 3D depth of zero), a plurality of display information with various 3D depths is prepared for the same display information. A method of selecting 3D display information from a plurality of display information and performing 3D display, converting 2D display information into display information having a predetermined 3D depth, and converting the converted display information to 3D Although there is a display method, 3D display generally has a drawback that it is difficult to see at a small display size, and the conversion method also has a disadvantage that power is consumed for the conversion process.
Therefore, conventionally, as a technique that makes it possible to switch the 3D depth by a user operation, for example, a technique for changing the depth of stereoscopic viewing by a user operation or switching between stereoscopic viewing and planar viewing has been disclosed. (See Patent Document 1).

JP 2007-037619 A

  However, in the above-described prior art, the user switches the appropriate 3D depth by the user operation each time depending on the situation, but switching by the user operation is complicated.

  An object of the present invention is to enable display control at an appropriate 3D depth according to the situation at the time when display information is displayed on a display unit.

Terminal of the present invention is a terminal device for 3D display unit to display the display information, among usage battery portion of the plurality of levels, the use condition detecting means for detecting whether any level, before Symbol A determining unit that determines a 3D depth of display information displayed on the display unit to be a 3D depth corresponding to a level of the usage status of the battery unit detected by the usage status detecting unit, and a 3D determined by the determining unit And a display control unit configured to display the display information on a display unit based on a depth.

FIG. 4 is a diagram for explaining the power saving mode storage unit M3.
The power saving mode storage unit M3 stores information indicating whether or not an operation mode for suppressing power consumption (power saving mode) is set, and corresponds to “ON” and “OFF” of the “item”. The “setting flag” attached indicates whether the power saving mode ON or the power saving mode OFF is currently valid, “1” is valid, and “0” is invalid. The contents of the “setting flag” are arbitrarily set by a user operation. In the power saving mode, for example, the operation of a specific function is limited, the brightness of the display unit 17 (for example, the brightness of the backlight in the case of a liquid crystal display unit) is reduced, or the output volume of the sound speaker 23 is reduced. This is an operation mode in which power consumption is suppressed by lowering the power.

FIG. 5 is a diagram for explaining the condition storage unit M4.
The condition storage unit M4 stores conditions for determining the 3D depth of the display information when the display information is displayed on the display unit 17, and includes “item”, “setting flag”, “content”, “ 3D depth ”, the central control unit 11 determines the 3D depth of the display information according to the current situation when displaying the display information on the display unit 17, and the 3D depth. The display information is displayed on the display unit 17. “Item” indicates the type of condition (situation) for determining the 3D depth. In this “item”, “display size”, “remaining battery power”, and “power saving mode” determine the 3D depth. It is stored as a condition to do.

  “Display size” is based on the display size when display information is displayed on the display unit 17, and the central control unit 11 determines the condition (display information) based on the display size of the display information (status of display information). The 3D depth of the display information is determined by referring to the (display size), and the display information is displayed in 3D at this 3D depth. The “remaining battery level” is based on the current remaining battery level (usage of operating power) detected by the battery unit 12 when displaying the display information on the display unit 17. The central control unit 11 The 3D depth of the display information displayed on the display unit 17 is determined by referring to the condition (battery remaining amount) based on the current battery remaining amount, and the display information is displayed on the display unit 17 at the 3D depth. It is made to display. The “power saving mode” is a condition that the power saving mode is turned on / off (usage of operating power) when displaying the display information on the display unit 17. By referring to the condition (power saving mode) based on on / off, the 3D depth of the display information displayed on the display unit 17 is determined, and the display information is displayed on the display unit 17 at this 3D depth. ing.

  The “setting flag” is a flag indicating a currently valid condition. “1” is valid and “0” is invalid. The “setting flag” can be arbitrarily set by a user operation, and the currently effective condition may be any one or a combination of a plurality of conditions. The illustrated example shows a case where the “display size” condition is valid and the “battery remaining amount” and “power saving mode” conditions are invalid. “Content” specifically indicates the content of the corresponding condition, and stores a plurality of contents to be described later. “3D depth” indicates the 3D depth of display information or the degree of pop-up, and is associated with each “content”, and is determined according to which “content” condition the current situation corresponds to. 3D is shown. In the illustrated example, when the “item” of the condition is “display size”, the “content” includes “50000 (pixel × pixel) or more”, “30000-49999”, “10000-29999”, “10000”. Less than "is set. Further, “level 3”, “level 2”, “level 1”, and “level 0 (2D)” are set in “3D depth” corresponding to each “content” of this condition.

  Here, the larger the display size of the display information is, the deeper the 3D depth is. For example, when the display size of the display information is “30000-49999” and is larger than a predetermined display size (10000 to 29999), the display is displayed at a 3D depth (level 2) larger than the predetermined 3D depth (level 1). Information is displayed in 3D. Similarly, when the display size of the display information is “50000 or more” and larger than the predetermined display size (“30000-49999”), the 3D depth (level 3) is larger than the predetermined 3D depth (level 2). The display information is displayed in 3D. When the display size of the display information is small, the 3D depth is set to zero. For example, when the display size of the display information is smaller than a predetermined display size (10000), 2D display is performed with the 3D depth at level 0.

  In the illustrated example, the display size of the display information is expressed as an area size (pixel × pixel) as “content” of “display size”. However, the present invention is not limited to this. For example, the vertical size (pixel) Only the horizontal size (pixel) may be used to represent the display size. Further, “level 0 (2D)” of “3D depth” indicates that the 3D depth is “level 0 (zero)” and is 2D (plane). In the example shown in the figure, “3D depth” is expressed as a level. However, the present invention is not limited to this, and may be expressed in another unit such as millimeters.

When the “item” of the condition is “remaining battery level”, the “content” includes “remaining level 3”, “
“Remaining level 2” and “Remaining level 0 to 1” are set, and “3D depth” corresponding to each “content” of this condition includes “level 3”, “level 2”, “ “Level 1”, “Level 0 (2D)”
Is set. Here, the remaining amount level 3> the remaining amount level 2> the remaining amount level 0 to 1, and the 3D depth becomes shallower as the remaining battery level is smaller.

For example, when the remaining battery level is lower than a predetermined remaining level (remaining level 3), display information is displayed in 3D at a 3D depth (level 2) smaller than a predetermined 3D depth (level 3). . Similarly, when the remaining battery level is lower than the predetermined remaining level (remaining level 2), the display information is displayed in 2D at a 3D depth (level 0) smaller than the predetermined 3D depth (level 1). Yes. When the “item” of the condition is “power saving mode”, “content saving” is set to “power saving mode off” and “power saving mode on”. The “3D depth” corresponding to each “content” of this condition includes “level 3” and “level 0 (2D)”.
Is set. Here, if the power saving mode is turned on, 2D display is performed, and if the power saving mode is turned off, 3D display is performed. That is, when the power saving mode is turned on, display information is displayed in 2D at a 3D depth (level 0) smaller than a predetermined 3D depth (level 3).

FIG. 6 is a diagram for explaining a modified example of the condition storage unit M4. In the above-described embodiment, a plurality of values are provided for each condition of “display size”, “remaining battery power”, and “power saving mode”. However, as shown in FIG. 6, one “content” is stored in the conditions of “display size”, “remaining battery power”, and “power saving mode”. Also good. The condition storage unit M4 includes “items”, “contents”, and “setting flags”, and “3D depth” shown in FIG. 5 is included in “contents”. For example, in the example of FIG. 6, “content” with the condition “display size” is set to “3D with 256 × 256 pixels or more”, and if the display size is 256 × 256 pixels or more, the display information is 3D. Is displayed. In addition, in the “content” of the condition “remaining battery level”, “2D when the remaining level is 1 or less”
Is set, and if the current remaining battery level is level 1 or less, the display information is displayed in 2D. The “content” of the condition “power saving mode” is set to “2D when the power saving mode is on”, and if the power saving mode is on, the display information is displayed in 2D.

FIG. 7 is a diagram for explaining the display information storage unit M5.
The display information storage unit M5 stores display information to be displayed on the display unit 17. For example, information such as moving images, still images, music, and news from the information distribution device 4 is transmitted to the Internet 3 and the wireless communication network 2. The information that is downloaded via the TV broadcast or received by the television broadcast receiver 16 is recorded and stored as display information. The display information storage unit M5 stores “title”, “type”, “3D depth”, “display information size”, “actual data”, and the like corresponding to “information ID” for identifying display information. “Type” is information for identifying the type of display information (moving image, still image, text, menu, etc.).

  “Display information size” indicates the actual size (area size) of display information, and is represented by size vertical pixels × horizontal pixels. “Actual data” is actual data of display information, and there is display information having only actual data whose “3D depth” is “level 0 (for 2D display)”, or display information having actual data of each 3D depth. There is also. That is, there is display information having actual data (including 2D display) for each 3D depth even with the same content, and there is display information having only actual data with a 3D depth of level 0 (2D display).

  Next, the operation concept of the mobile phone 1 in the present embodiment will be described with reference to the flowcharts shown in FIGS. Here, each function described in these flowcharts is stored in the form of a readable program code, and operations according to the program code are sequentially executed. In addition, the operation according to the above-described program code transmitted via the transmission medium can be sequentially executed. In other words, in addition to the recording medium, the operation unique to the present embodiment can be executed using a program / data supplied externally via a transmission medium such as a network.

FIG. 8 is a flowchart showing an overview of the overall operation on the mobile phone 1 side which is started to be executed when the power is turned on.
First, in the mobile phone 1, when the power-on operation for turning on the power is performed (YES in Step A1), the central control unit 11 starts the power supply and executes a power-on process for initializing a predetermined memory and the like. After that, standby processing is performed in which a predetermined standby image is read and displayed, or communication is performed with the base station 2A to perform location registration (step A2).

  Here, when a setting operation for setting arbitrary information is performed (YES in step A3), for example, a setting for the condition storage unit M4 and the display information storage unit M5 is performed as a setting process corresponding to the operation. (Step A4). That is, the “content” of each condition is set in the condition storage unit M4. Also, a process of downloading information such as moving images, still images, music, news, etc. from the information distribution device 4 or recording and recording a broadcast program received by the television broadcast receiving unit 16 and storing it in the display information storage unit M5 And so on. When such setting processing ends, the process returns to step A3 described above.

  When a display information display operation is performed, that is, when a display operation instructing display information such as an image, text, or menu to be displayed on the display unit 17 is detected by a user operation (YES in step A5), the display information is displayed. The display information determination process A for determining the display direction and the display size is executed (step A6), and after the 3D depth determination process A for determining the 3D depth of the display information is executed (step A7), the determined display direction Then, the process proceeds to a display process for displaying the display information based on the display size and the 3D depth (step A8).

FIG. 9 is a flowchart for explaining the display information determination processing A (step A6 in FIG. 8) in detail.
First, the central control unit 11 operates the display unit direction detection unit 26 to detect the direction of the display unit 17 (vertical orientation / horizontal orientation) (step B1), and then displays information about the direction of the display unit 17 Display direction is determined (step B2). That is, regardless of whether the direction of the display unit 17 is portrait or landscape, the display unit direction detection unit 26 is set so that the display information is in the correct direction (so that the vertical direction of the display information is directed to the direction of gravity). The display information display direction with respect to the direction of the display unit 17 is determined based on the direction of the display unit 17 detected by the above.

  Then, after accessing the display information storage unit M5 and reading “display information size” associated with the display information instructed to be displayed by the user operation (step B3), the display size of the display information is determined (step B3). B4). In this case, the display direction of the display information determined as described above and the display direction of the display information that has been read and the display information that has been read are displayed so that the display area is displayed without changing the aspect ratio. The display size of the display information is determined (calculated) based on “size” and the size of the display area. The display direction and the display size of the display information thus determined are temporarily stored in various information temporary storage unit M2 (step B5).

FIG. 10 is a flowchart for explaining in detail the 3D depth determination processing A (step A7 in FIG. 8).
First, the central control unit 11 accesses the condition storage unit M4, reads a condition in which the “setting flag” is “1” (step C1), whether the condition is “display size” (step C2), “battery If it is “display size” (YES in step C2), the display size determined in the display information determination process A (step A6 in FIG. 8) is In order to check which “content” of the condition (display size) corresponds, each “content” of the condition is compared with the determined display size (step C3).

  Here, in the display size comparison, the “content” of the condition is the area size, but if the determined display size is the vertical size or the horizontal size, the comparison with the vertical size or the horizontal size is performed. As a result, “3D depth” corresponding to the “content” corresponding to which “content” corresponds to “content” of “less than 10000”,. The depth is determined (step C4). In this case, the larger the display size of the display information, the larger the 3D depth is determined. If the display size is smaller than the predetermined display size, the 3D depth is determined as zero. Then, the determined 3D depth is temporarily stored in the various information temporary storage unit M2 (step C5).

  If the condition of the “setting flag” is “1” is “remaining battery power” (YES in step C6), the “content” of the condition, the remaining capacity of the secondary battery detected by the battery unit 12, and (Step C7), “3D depth” corresponding to “content” (remaining battery level) of the corresponding condition is determined as 3D depth of display information (step C8), and various information temporary storage units M2 (Step C5). If the condition of “setting flag” “1” is “power saving mode” (NO in step C6), the “content” of the condition is compared with the current power saving mode on / off. (Step C9), “3D depth” corresponding to “content” (on / off of the power saving mode) of the corresponding condition is determined as the 3D depth of the display information (step C10), and is stored in the various information temporary storage unit M2. Temporary storage is performed (step C5).

FIG. 11 is a flowchart for explaining the display process (step A8 in FIG. 8) in detail.
First, the central control unit 11 refers to the display information storage unit M5 and checks whether the “3D depth” determined in the 3D depth determination process A (step A7 in FIG. 8) is “level 0”. (Step D1) If “level 0” is 2D (planar) (YES in Step D1), this display information is displayed in 2D. At this time, if a parallax barrier is generated on the surface of the display unit 17 After removing the parallax barrier (step D2), 2D display is performed on the display unit 17 with the display direction and display size determined in the display information determination processing A (step A6 in FIG. 8) (step D3). In this way, based on the display size of the display information, it is determined whether or not the 3D depth of the display information is to be zero, and when it is to be zero, the display information is displayed on the display unit 2D.

  If the “3D depth” determined in the display information determination process A is not “level 0” (NO in step D1), the display information storage unit M5 is searched based on the “3D depth” of the display information. Then, the presence / absence of the corresponding “real data” is checked (step D4). In other words, “real data” includes display information having only real data having “3D depth” of “level 0” and display information having real data of each 3D depth. Check for "real data". As a result, if there is corresponding “real data” (YES in step D4), “real data” associated with “3D depth” determined in the display information determination processing A is selected and read (step D5). Then, the display information is displayed in 3D. At that time, after the parallax barrier is generated on the surface layer of the display unit 17 (step D6), the display direction determined by the display information determination processing A (step A6 in FIG. 8) and 3D display is performed on the display unit 17 in the display size (step D7).

  If there is no “actual data” of the corresponding “3D depth” (NO in step D4), that is, “actual data” of a 3D depth different from the determined 3D depth (for example, depth level “0”). If it is stored only, the display information for the right eye and the left eye corresponding to the determined 3D depth in order to convert the “real data” of another 3D depth into the 3D display information of the determined 3D depth. Display information is generated (step D8). Then, after the parallax barrier is generated on the surface layer of the display unit 17 (step D6), the display information is displayed in 3D on the display unit 17 with the determined display direction and display size (step D7). If “actual data” of the corresponding “3D depth” is not stored in this way, “actual data” of 3D depth different from the determined 3D depth is converted into 3D display information of the determined 3D depth. To display in 3D.

  On the other hand, when a change operation for changing the display size of the display information displayed on the display unit 17 is detected (YES in step A9 in FIG. 8), a display for determining a new display size by this display size change operation. After executing the information determination process B (step A10), and after executing the 3D depth determination process B that determines the 3D depth of the display information based on the newly determined display size (step A11), the determined display The process proceeds to a display process for displaying display information based on the size and the 3D depth (step A8). That is, when the display size of the display information displayed on the display unit 17 is changed, the 3D depth of the display information is newly determined based on the changed display size, and the display is performed at the new 3D depth. The information is switched and displayed.

FIG. 12 is a flowchart for explaining the display information determination process B (step A10 in FIG. 8) in detail.
First, the central control unit 11 determines the display size designated by the display size changing operation as the display size of the display information (step E1), and then sets the display size after the change to the display direction of the display information (the above-described display Along with the original display direction determined in the information determination process A, that is, the display direction before the display size is changed, the information is temporarily stored in the various information temporary storage unit M2 (step E2).

FIG. 13 is a flowchart for explaining in detail the 3D depth determination process B (step A11 in FIG. 8).
First, the central control unit 11 accesses the condition storage unit M4, reads the condition where the “setting flag” is “1” (step F1), and checks whether the condition is “display size” (step F2). If it is not “display size” (NO in step F2), the process returns to step A3 in FIG. 8, but if it is “display size” (YES in step F2), the display size determined by the display information determination process B described above. In order to examine which “content” of this condition (display size) corresponds, each “content” of this condition is compared with the determined display size (step F3). As a result, “3D depth” corresponding to the corresponding “content” is displayed according to which “content” of “less than 10000”,. 3D depth (step F4) and temporarily stored in various information temporary storage unit M2 (step F5).

  When the display size of the display information is changed in this way, the 3D depth is changed based on the changed display size, and thus the changed display size and 3D depth and the original display direction that has already been temporarily stored. The display processing for displaying the display information is performed based on (Step A8 in FIG. 8). In this case, 2D display or 3D display is performed according to the changed 3D depth level (steps D1 to D8 in FIG. 11).

  If it is detected that the direction of the display unit 17 has been changed (YES in step A12 in FIG. 8), the above-described display information determination is performed to newly determine the display direction and display size of the display information in accordance with the change. After executing the process A (step A13), after executing the 3D depth determination process B for determining a new 3D depth of display information based on the newly determined display direction and display size (step A14), The process proceeds to display processing for displaying display information based on the determined display direction, display size, and 3D depth (step A8). In this case, in the display information determination process A, the changed direction of the display unit 17 is detected (step B1 in FIG. 9), and the display direction of the display information is determined based on this new direction (step B2). Then, after reading the “display information size” associated with the displayed display information (step B3), the display size of the display information is determined (step B4). In this case, the display direction of the determined display information, the read “display information size”, the display area size, and the display area so that the display area is displayed in the new display direction without changing the aspect ratio. Based on the size, the display size of display information is determined (calculated). The display direction and the display size of the display information thus determined are temporarily stored in various information temporary storage unit M2 (step B5).

  When a change in the remaining battery level in the battery unit 12 is detected (YES in step A15 in FIG. 8), a 3D depth determination process C for newly determining the 3D depth of the display information based on the change in the remaining battery level is performed. After execution (step A16), the process proceeds to a display process for displaying display information based on the determined 3D depth (step A8). That is, the 3D depth of the display information displayed on the display unit 17 is determined based on the remaining battery level (usage of operating power), and the display information is displayed on the display unit 17 at this 3D depth.

FIG. 14 is a flowchart for explaining in detail the 3D depth determination process C (step A16 in FIG. 8).
First, the central control unit 11 accesses the condition storage unit M4, reads the condition where the “setting flag” is “1” (step G1), and checks whether the condition is “remaining battery level” (step G2). If it is not “remaining battery power” (NO in step G2), the process returns to step A3 in FIG. 8, but if it is “remaining battery power” (YES in step G2), the current remaining battery capacity is determined according to this condition ( In order to check which “content” of the “remaining battery level” corresponds to each “content” of this condition, the current remaining battery level is compared (step G3). As a result, the “remaining level 0-1”, “remaining level 2”, and “remaining level 3” “contents” corresponding to which “content” corresponds to “ “3D depth” corresponding to “content” is determined as the 3D depth of the display information (step G4). In this case, the smaller the remaining battery level, the smaller the 3D depth is determined. Then, the determined “3D depth” is temporarily stored in the various information temporary storage unit M2 (step G5).

  When the remaining battery level is changed in this manner, the 3D depth is changed based on this change. Therefore, the changed 3D depth and the original display size and display direction that have already been temporarily stored, that is, the remaining battery level. Display processing for displaying the display information is performed based on the display size and the display direction before the change (step A8 in FIG. 8). In this case, 2D display or 3D display is performed according to the 3D depth level after the remaining battery level is changed (steps D1 to D8 in FIG. 11).

  Further, when an operation for instructing the change of the power saving mode is detected (YES in step A17 in FIG. 8), the 3D depth determination process D is executed to newly determine the 3D depth of the display information based on the change operation. Thereafter (step A18), the process proceeds to a display process for displaying display information based on the determined 3D depth (step A8). In other words, the 3D depth of the display information displayed on the display unit 17 is determined based on the power saving mode (usage of operating power), and the display information is displayed on the display unit 17 at this 3D depth.

FIG. 15 is a flowchart for explaining the 3D depth determination process D (step A18 in FIG. 8) in detail.
First, the central control unit 11 changes the setting flag of the power saving mode storage unit M3 in accordance with the power saving mode changing operation in step A17 (step H1). When the power saving mode is set to ON by the power saving mode changing operation, the “setting flag” of “ON” is set to “1”, and the “setting flag” of “OFF” is set to “0”. When the power saving mode is set to OFF, the “setting flag” for “ON” is set to “0”, and the “setting flag” for “OFF” is set to “1”. Here, when the power saving mode is set to ON, the power saving operation is started from that point.
Next, the central control unit 11 accesses the condition storage unit M4, reads the condition where the “setting flag” is “1” (step H2), and checks whether the condition is the “power saving mode” (step H3). ), If it is not “power saving mode” (NO in step H3), the process returns to step A3 in FIG. 8, but if it is “power saving mode” (YES in step H3), the newly designated power saving mode is In order to check which “content” of this condition (power saving mode) corresponds, each “content” of this condition is compared with the new power saving mode (step H4).

  As a result, the “3D depth” corresponding to the corresponding “content” depends on which “content” of “power saving mode on” and “power saving mode off”. Is determined as the 3D depth of the display information (step H5). In this case, if the power saving mode is “ON”, “level 0” is determined as the 3D depth, and if the power saving mode is “OFF”, “level 3” is determined as the 3D depth. Then, the determined “3D depth” is temporarily stored in the various information temporary storage unit M2 (step H6).

  When the power saving mode is changed in this way, the 3D depth is changed based on this change. Therefore, the changed 3D depth and the original display size and display direction that have already been temporarily stored, that is, the power saving mode. Display processing for displaying the display information based on the display size and the display direction before the change is made is performed (step A8 in FIG. 8). In this case, 2D display or 3D display is performed according to the 3D depth level after the power saving mode is changed (steps D1 to D8 in FIG. 11).

  On the other hand, when an incoming call is detected (YES in step A19 in FIG. 8), the telephone is set in a call ready state, and after executing a call process for storing a call history and displaying information related to the call (step A20), The process returns to step A3. Further, when a power-off operation is performed (YES in step A21), a power-off process is executed (step A22), and the flow of FIG. 8 ends. When other operations are performed (step A22) As a process corresponding to the operation, for example, a display erasure process for erasing the contents of the display unit 17, a call transmission process, a mail transmission process, and the like are executed (step A24), and the process returns to the above-described step A3. .

  As described above, in the present embodiment, the central control unit 11 determines the 3D depth of the display information displayed on the display unit 17 based on the display size when the display information is displayed in 3D on the display unit 17. Since the display information is displayed in 3D at the 3D depth, the display information can be displayed at an appropriate 3D depth according to the display size of the display information.

  When the display size of the display information displayed on the display unit 17 is larger than the predetermined display size, the 3D depth is determined to be a 3D depth larger than the predetermined 3D depth. By displaying large display information, it is possible to provide the user with a powerful and realistic 3D display.

  Based on the display size of the display information displayed on the display unit 17, it is determined whether or not the 3D depth of the display information is to be zeroed. Since display is performed, display control can be performed by appropriately determining whether 3D display or 2D display is performed based on the display size of the display information.

  When the display size of the display information displayed on the display unit 17 is smaller than the predetermined display size, the 3D depth is determined to be zero. Therefore, when it is difficult for the user to see the display information in the 3D display, the 2D display is performed. can do. In addition, in the case of a system that 3D-converts “actual data” with a 3D depth of zero, the process of 3D conversion can be omitted by performing 2D display. When the display size is small and 3D display is difficult to see, it is very effective to make it easier to see with 2D display, and omitting the processing of 3D conversion is also extremely effective from the viewpoint of reducing unnecessary processing and power consumption. .

  Since the display size of the display information is detected based on the size of the display information displayed on the display unit 17 and the size of the display area of the display unit 17, the 3D display is appropriately performed based on the display size of the display information. Display control can be performed by determining whether the display is 2D.

  When the display size of the display information is changed, the 3D depth of the display information is determined based on the display size after the change, and the display information is changed and displayed at the 3D depth. When it is done, the display information can be displayed at an appropriate 3D depth according to the changed display size.

  Since “actual data” of a 3D depth different from the determined 3D depth is converted into 3D display information of the determined 3D depth and displayed in 3D, a plurality of display information having different 3D depths are prepared in advance. This eliminates the need to create and store a large amount of information, and is advantageous in terms of storage capacity.

  Since the display information of the determined 3D depth is selected from the plurality of display information having different 3D depths to be displayed in 3D, the 3D conversion process can be omitted.

  Since the 3D depth of the display information displayed on the display unit 17 is determined based on the usage state of the operation power, the display information is displayed on the display unit 17 at this 3D depth. Accordingly, display information can be displayed at an appropriate 3D depth.

  Since the 3D depth of the display information displayed on the display unit 17 is determined based on the remaining battery level (usage of operating power), the display information is displayed at an appropriate 3D depth according to the remaining battery level. be able to.

  When the remaining amount of power for operation is less than the predetermined remaining amount, the 3D depth is determined to be smaller than the predetermined 3D depth, so when the remaining battery power is low, that is, when power consumption should be suppressed Power consumption can be reduced by displaying display information with a small 3D depth.

  Since the 3D depth is determined to be zero and the display information is displayed in 2D when the remaining battery level is less than the predetermined remaining level, this is displayed when the remaining battery level is low, that is, when power consumption should be suppressed. By displaying information in 2D, power consumption can be reduced. In the case of the 3D conversion method, the 3D conversion process can be omitted by performing 2D display. Omitting the 3D conversion process is extremely effective from the viewpoint of unnecessary processing and reduction of power consumption.

  Since the 3D depth of the display information displayed on the display unit 17 is determined based on whether or not the power saving mode is set, an appropriate 3D depth is determined depending on whether or not the power saving mode is set. Display information can be displayed.

  When the power saving mode is set, the 3D depth is determined to be smaller than the predetermined 3D depth. Therefore, when the power consumption should be suppressed, display information with a small 3D depth is displayed, thereby reducing the power consumption. The power consumption can be reduced according to the state at that time.

  When the power saving mode is set, the 3D depth is determined to be zero and the 2D display is performed. Therefore, when the power consumption should be suppressed, the 2D display can reduce the power consumption. Power consumption can be reduced according to the state of the time.

  In the above-described embodiment, the types of display information displayed on the display unit 17 include display information distributed from the information distribution device 4, display information (television program) transmitted from the television station 5, text, menus, and the like. However, the present invention is not limited to this. For example, in the mobile phone 1 having a photographing unit, display information (image) photographed by the photographing unit, various setting screens, and a volume setting screen at the time of moving image reproduction. For example, display information of an arbitrary type displayed on the display unit 17 may be used.

  In the embodiment described above, the display information stored in the storage unit 13 is displayed as display information to be displayed on the display unit 17. However, the display information is not limited to this, and display information distributed from the information distribution device 4 is received. The display information may be arbitrary display information displayed on the display unit 17, such as sequentially displaying (streaming reproduction) or sequentially displaying while receiving display information (television program) transmitted from the television station 5.

  In the above-described embodiment, the 3D display information is displayed in accordance with the 3D depth so that the display information for the right eye and the display information for the left eye corresponding to the 3D depth are displayed at the same time so that they appear correctly in 3D. The method of generating the 3D display by generating the parallax barrier on the surface layer of the display unit 17 has been exemplified, but any method such as a method of performing the 3D display by applying a visual effect that makes the object in the display information look 3D is arbitrary. The 3D display method may be used.

  The display information display method on the display unit 17 (the display direction of the display information on the display unit 17 and the display size of the display information) may be any display method. In the above-described embodiment, the “display direction of the display information with respect to the display unit 17” detects the direction of the display unit 17 and determines the display direction of the display information with respect to the display unit 17 based on the detection result. However, for example, (1) If the display information is vertically long, the display direction is set so that the display portion 17 can be correctly viewed when the display portion 17 is vertically long. If the display information is horizontally long, the display information is correctly displayed when the display portion is horizontally long. (2) If it is an open style, it will be displayed correctly when the display unit 17 is vertically long. If it is a view style, it will be displayed correctly when the display unit 17 is horizontally long. This is a method for determining an arbitrary display direction such as (3) the display direction specified by the display information, (4) the display direction specified by the user operation. It may be. In the above-described embodiment, the “display size of display information” is determined so that the display area is displayed in the determined display direction without changing the aspect ratio. Change the display size so that it can be displayed in the full display area, (2) Display size specified by display information, (3) Display size specified by user operation, etc. The determination method may be used.

  In the above-described embodiment, when the actual data of the determined 3D depth is not stored, the actual data of another 3D depth is converted to the actual data of the determined 3D depth. You may make it request | require and receive real data of 3D depth from an information delivery apparatus.

  In addition, the storage unit 13 may be any external storage device such as a memory card or an external hard disk. The display unit 17 may be an arbitrary external display device such as an external monitor. The terminal device is not limited to a mobile phone, and may be any terminal device such as a personal computer, a PDA, a digital camera, or a music player. Furthermore, it is not limited to a folding type terminal device, but may be an arbitrary housing structure such as a straight type, a slide type, or a spin top type.
