[First embodiment]
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a configuration diagram illustrating an example of a configuration of an electronic device 1 according to the first embodiment of the present invention.

  The electronic device 1 is a double-sided display device, and includes a first surface 101 and a second surface 102 that are in a front-to-back positional relationship. The electronic apparatus 1 includes a first display unit 11 on a first surface 101 and a second display unit 12 on a second surface 102. The electronic apparatus 1 may be, for example, a desktop stationary display device, or may be a tablet display device that can be held by the operator U1 as shown in FIG. Hereinafter, a case where the electronic device 1 is placed on a desk and the operator U1 and the partner U2 of the operator U1 face each other will be described as an example. In this case, the surface viewed by the operator U1 is the first surface 101, and the surface viewed by the operator U2 is the second surface 102.

Here, a display example by the conventional double-sided display device D will be described with reference to FIG.
FIG. 11 is a schematic view showing a display example by the conventional double-sided display device D. As shown in FIG. As shown in FIG. 11A, the double-sided display device D includes a first display unit D1 and a second display unit D2. The first display unit D1 displays an image for the operator U1. The second display unit D2 displays an image on the partner U2 of the operator U1. Here, when the double-sided display device D is placed on the desk TBL, the posture of the double-sided display device D is set so that the image displayed on the first display unit D1 can be easily viewed by the operator U1. In this example, the posture that is easy for the operator U1 to see is, as shown in FIG. 11B, the angle θ1 formed by the desk TBL and the first display portion D1 exceeds a certain angle (for example, 90 [°]). This is the attitude. At this time, the angle θ2 formed by the second display unit D2 and the desk TBL is equal to or smaller than a certain angle (for example, 90 [°]). For this reason, it becomes difficult for the partner U2 to see the second display portion D2. In other words, according to the conventional double-sided display device D, when the operator U1 makes the first display unit D1 easy to see the posture of the double-sided display device D, the second display unit D2 is difficult to see from the partner U2 of the operator U1. It becomes a state.
On the other hand, according to the electronic device 1 of the present embodiment, an easy-to-see image can be displayed on both the operator U1 and the partner U2. The configuration of the electronic apparatus 1 will be described with reference to FIGS.

  FIG. 2 is a configuration diagram illustrating an example of an external configuration on the first surface 101 side of the electronic apparatus 1 in the present embodiment. As shown in FIG. 2, the electronic device 1 includes a first display unit 11 and a first operation detection unit 21 on a first surface 101 (first display surface). The first display unit 11 includes a liquid crystal display, for example, and displays an image. In the following description, a position where the operator U1 views the electronic device 1 is also referred to as a first viewpoint position. The electronic device 1 displays an image so that the image displayed on the first display unit 11 can be observed when the operator U1 views the first surface 101 from the first viewpoint position. That is, the first display unit 11 displays an image in the direction of the first viewpoint position. Here, “observable” means that the displayed image is easy to observe (easy to see). For example, when an image displayed on a liquid crystal display is observed from within the viewing angle of the liquid crystal panel, the displayed image is easier to observe than when viewed from outside the viewing angle. In this case, “observable” means that the first display unit 11 can be observed from within the viewing angle of the first display unit 11 when viewed from the first viewpoint position.

  The first operation detection unit 21 includes a contact sensor and detects a contact state with respect to the first display unit 11. The first operation detection unit 21 detects an operation on the first display unit 11 by detecting a contact state on the first display unit 11. For example, when the operator U1 taps the first display unit 11 with a finger, the first operation detection unit 21 detects the tapped position.

  FIG. 3 is a configuration diagram illustrating an example of an external configuration on the second surface 102 side of the electronic apparatus 1 in the present embodiment. As shown in FIG. 3, the electronic device 1 includes a second display unit 12 and a second operation detection unit 22 on the second surface 102 (second display surface). Similar to the first display unit 11, the second display unit 12 includes a liquid crystal display, for example, and displays an image on the surface opposite to the first surface 101, that is, the second surface 102. The second display unit 12 can display an image by switching between a stereoscopic display (three-dimensional display) that displays a virtual image in space and a non-stereo display (two-dimensional display) that does not display a virtual image in space. is there. That is, the second display unit 12 can display an image by switching between the 3D display mode and the 2D display mode. In the following description, the first display unit 11 and the second display unit 12 are collectively referred to simply as “display unit”. The three-dimensional display mode is also described as a first display mode. The two-dimensional display mode is also described as a second display mode. In addition, the position where the partner U2 views the electronic device 1 is also referred to as a second viewpoint position. The electronic device 1 displays an image so that the image displayed on the second display unit 12 can be observed when the opponent U2 views the second surface 102 from the second viewpoint position. That is, the second surface 102 (second display surface) displays an image in the direction of the second viewpoint position different from the direction of the first viewpoint position.

  Similar to the first operation detection unit 21, the second operation detection unit 22 includes a contact sensor such as a touch panel, and detects a contact state with respect to the second display unit 12. The second operation detection unit 22 detects an operation on the second display unit 12 by detecting a contact state on the second display unit 12. For example, when the partner of the operator U1 taps the second display unit 12 with a finger, the second operation detection unit 22 detects the tapped position.

  The contact sensors included in the first operation detection unit 21 and the second operation detection unit 22 described above are touch panel type operation input devices, for example, electrostatic capacitance type contact sensors. The contact sensor may be an electromagnetic induction method, an infrared method, a surface acoustic wave method, a resistance film method, or a matrix switch method instead of the capacitance method. Further, the contact sensor may be a so-called multi-touch panel system that can detect multiple contacts at the same time and can input multiple points. The electronic device 1 performs various operations based on the operations detected by the first operation detection unit 21 and the second operation detection unit 22, respectively. The details of this operation are not described here. In the following description, the first operation detection unit 21 and the second operation detection unit 22 are collectively referred to simply as “operation detection unit”.

  FIG. 4 is a configuration diagram illustrating an example of a functional configuration of the electronic device 1 in the present embodiment. As shown in FIG. 4, the electronic device 1 includes a storage unit 30, a posture detection unit 40, a control unit 50, and a bus 80 therein. In FIG. 4, parts corresponding to those in FIGS. 2 and 3 are given the same reference numerals.

  The bus 80 is connected to the first display unit 11, the second display unit 12, the first operation detection unit 21, the second operation detection unit 22, the storage unit 30, the posture detection unit 40, and the control unit 50, and outputs from each unit. The transferred image information, control information, etc. are transferred.

  The storage unit 30 stores control information such as a program executed by the control unit 50 and image information of an image displayed on each display surface. The control unit 50 reads these pieces of information from the storage unit 30 via the bus 80, executes the program, and displays an image on each display surface. The storage unit 30 also temporarily stores the results calculated when the control unit 50 displays an image on each display surface.

  The posture detection unit 40 includes, for example, a tilt sensor and detects the posture of the electronic device 1. Here, the attitude of the electronic device 1 may be the angle of the first surface 101 (or the second surface 102) with respect to the direction of gravity, or the surface on which the electronic device 1 is placed (for example, the desk TBL). It may be an angle of the first surface 101 (or the second surface 102) with respect to the upper surface. In addition, the posture detection unit 40 may include a camera that captures surrounding images. In this case, the posture detection unit 40 detects the angle formed by the line of sight of the partner U2 and the display surface of the second display unit 12 as the posture of the electronic device 1 based on the image captured by the camera. That is, the attitude of the electronic device 1 may be an angle formed between the line of sight of the opponent U2 and the display surface of the second display unit 12. Further, the posture detection unit 40 may detect the posture of the electronic device 1 by acquiring information indicating the posture of the electronic device 1 from a device external to the electronic device 1. For example, a captured image is acquired from a camera that captures the posture of the electronic device 1 by wireless or wired communication, and the image of the electronic device 1 included in the acquired image is processed, thereby changing the posture of the electronic device 1. It may be detected. Hereinafter, a case where the posture detection unit 40 detects the angle of the first surface 101 with respect to the direction of gravity as the posture of the electronic device 1 will be described as an example.

The control unit 50 includes an operation control unit 51 and a display control unit 52.
The operation control part 51 controls the operation | movement with respect to the operation which each operation detection part (The 1st operation detection part 21 and the 2nd operation detection part 22) detects. For example, when each operation detection unit detects a character input operation, the operation control unit 51 controls an operation of converting the input character into a character code.

  The display control unit 52 controls the display operation of each display unit (the first display unit 11 and the second display unit 12). Specifically, the display control unit 52 performs an operation of selecting and displaying information to be displayed on each display unit, an operation of switching the display of each display unit on (display state) and off (non-display state), and the like. Control. Here, the information to be displayed on each display unit may be any of information to be displayed on the display unit such as an image, information on characters or icons, a menu screen, or the like.

  In addition, the display control unit 52 switches the display mode of the second display unit 12 according to the attitude of the electronic device 1. As described above, the posture of the electronic device 1 is detected by the posture detection unit 40. That is, the display control unit 52 switches the display mode of the second display unit 12 according to the attitude of the electronic device 1 detected by the attitude detection unit 40. In other words, when the posture of the electronic device 1 is the first posture, the display control unit 52 sets the display mode of the image displayed on the second display unit 12 as the first display mode, and the posture of the electronic device 1 is the first posture. In the case of the second posture different from the first display mode, the display mode of the image displayed on the second display unit 12 is set as the second display mode, and the display mode of the image displayed on the second display unit 12 is observable from the second viewpoint position direction. To control.

  Specifically, the display control unit 52 displays the second display unit 12 two-dimensionally according to the angle of the first surface 101 with respect to the direction of gravity detected by the posture detection unit 40, that is, the display angle of the first display unit 11. Switch between mode and 3D display mode. That is, the display control unit 52 switches the display mode of the second display unit 12 according to the display angle of the first display unit 11. The display mode switching performed by the display control unit 52 will be described with reference to FIG.

  FIG. 5 is a schematic diagram illustrating an example of a display mode of the second display unit 12 in the present embodiment. As shown in the figure, when the electronic device 1 is placed on the desk TBL, the operator U1 shows the posture of the electronic device 1 and the posture in which the operator U1 can easily see the image displayed on the first display unit D1. To. In this example, the posture of the electronic device 1 that is easy for the operator U1 to see is a posture in which the angle formed by the desk TBL and the first display unit 11 is the angle θ1 shown in FIG. Here, the angle formed between the desk TBL and the second display unit 12 is an angle θ2 shown in FIG. At this time, by setting the angle θ1 to a certain angle (for example, 90 [°]) or more, the posture of the electronic device 1 becomes a posture that the operator U1 can easily see. In the following description, this “certain angle” is also referred to as a threshold angle. In the following description, an angle θ1 formed by the desk TBL and the first display unit 11 is also referred to as a display angle θ1 of the first display unit 11. Further, the angle θ2 formed between the desk TBL and the second display unit 12 is also referred to as the display angle θ2 of the second display unit 12.

  Hereinafter, in the description of each drawing, an XYZ rectangular coordinate system is set, and the positional relationship of each part will be described with reference to this XYZ rectangular coordinate system. A surface on which the electronic device 1 is placed is defined as an XZ plane, and a direction perpendicular to the XZ plane is defined as a Y-axis direction. Here, the X-axis direction is a direction in which the operator U1 and the partner U2 face the electronic device 1, and the Y-axis direction is a vertically upward direction of the electronic device 1.

  In the example of FIG. 5, when the angle θ1 is greater than or equal to a threshold angle (for example, 90 [°]), the angle θ2 is smaller than the threshold angle. 2 The display unit 12 becomes difficult to see. Therefore, the display control unit 52 can determine whether the second display unit 12 is difficult to see from the counterpart U2 by determining whether the angle θ2 is smaller than the threshold angle. Therefore, when the display control unit 52 determines that the angle θ2 is smaller than the threshold angle, the display mode of the second display unit 12 is switched so that the image displayed on the second display unit 12 can be easily viewed from the partner U2. Is displayed. Specifically, when the display control unit 52 determines that the angle θ2 is smaller than the threshold angle, the display mode of the second display unit 12 is switched from the two-dimensional display mode to the three-dimensional display mode, and the second display is performed. The image to be displayed on the unit 12 is displayed as a virtual image VI whose display angle is the angle θ3.

  In addition, instead of determining whether or not the angle θ2 is smaller than the threshold angle, the display control unit 52 compares the magnitude relationship between the angle θ1 and the angle θ2 to determine whether or not the second display unit 12 is. It is possible to determine whether or not it is difficult to see. Specifically, the display control unit 52 calculates the angle θ1 and the angle θ2 based on the attitude of the electronic device 1 detected by the attitude detection unit 40. If the display control unit 52 compares the calculated angle θ1 with the angle θ2 and determines that the angle θ2 is smaller than the angle θ1, the display control unit 52 displays an image to be displayed on the second display unit 12 with a display angle of the angle θ3. Is displayed as a virtual image VI.

  As described above, the display control unit 52 switches the display angle of the image from the angle θ2 to the angle θ3 by switching the display mode of the second display unit 12 from the two-dimensional display mode to the three-dimensional display mode. Can do. Thereby, the other party U2 can see the virtual image VI displayed at an easy-to-see angle (in this example, the angle θ3). That is, the electronic device 1 can display an easy-to-see image for both the operator U1 and the partner U2.

  In this example, the display control unit 52 preferably displays the virtual image VI with the angle θ3 set to an angle larger than 90 [°]. Thereby, the partner U2 can see the image (virtual image VI) with the line of sight downward (−Y direction). That is, the electronic device 1 can display an image that is easier to see by setting the angle θ3 to an angle larger than 90 [°].

  The angle θ3 is an angle corresponding to the angle θ1 that is the display angle of the first display unit 11. That is, the display control unit 52 switches the display angle of the image displayed on the second display unit 12 by setting the display angle (angle θ3) of the virtual image VI to an angle corresponding to the display angle θ1 of the first display unit 11. In other words, the display control unit 52 switches the display angle of the image displayed on the second display unit 12 with respect to the first display unit 11 according to the posture of the device itself. Thereby, the electronic device 1 corresponds to an angle (for example, the angle at which the operator U1 views the image displayed on the first display unit 11 and the angle at which the counterpart U2 views the virtual image VI displayed on the second display unit 12). , The same angle). That is, the electronic device 1 can display the virtual image VI at an angle that is easy for the partner U2 to see even when the image displayed on the first display unit 11 is at an angle that is easy for the operator U1 to see. That is, the electronic device 1 can display an easy-to-see image for both the operator U1 and the partner U2.

  In addition, although the display control part 52 demonstrated the example which switches the display mode of the 2nd display part 12 from 2D display mode to 3D display mode based on the attitude | position of the electronic device 1 which the attitude | position detection part 40 detected. Not limited to this. For example, the display control unit 52 may switch the display angle of the virtual image VI instead of switching the display mode. Specifically, when the display mode of the second display unit 12 is the three-dimensional display mode, the display control unit 52 displays the display angle of the virtual image VI based on the attitude of the electronic device 1 detected by the attitude detection unit 40. (An angle θ3) is set to an angle corresponding to the display angle θ1 of the first display unit 11, and the display angle of the virtual image VI is switched. Even if comprised in this way, the electronic device 1 can display the image which is easy to see in any of the operator U1 and the other party U2.

Next, the operation of the electronic apparatus 1 according to the present embodiment will be described with reference to FIG.
FIG. 6 is a flowchart illustrating an example of the operation of the electronic apparatus 1 according to the present embodiment. The electronic device 1 executes a series of processes shown in steps S10 to S30 at predetermined intervals (for example, every 0.1 second).

  The posture detection unit 40 detects the display angle displayed by the first display unit 11 (step S10; detection step). Specifically, the posture detection unit 40 detects the gravitational direction (for example, the −Y direction in FIG. 5), and based on the detected gravitational direction, the horizontal direction (for example, the X direction in FIG. 5). ) Is calculated. In addition, the posture detection unit 40 calculates an angle (for example, the angle θ1 in FIG. 5) formed by the device with respect to the calculated horizontal direction based on the detected gravity direction. In addition, the posture detection unit 40 outputs the calculated angle formed by the own device as the display angle θ1 of the first display unit 11 to the display control unit 52 via the bus 80.

  The display control unit 52 determines whether or not the display angle θ1 detected by the posture detection unit 40 in step S10 exceeds a predetermined angle (step S20; display control step). Here, the predetermined angle is, for example, 90 [°]. In this example, the display control unit 52 determines whether or not the angle θ1 shown in FIG. 5 exceeds 90 [°]. Here, when the angle θ1 exceeds 90 [°], the angle θ2 shown in FIG. 5 is smaller than 90 [°]. The state where the angle θ1 exceeds 90 [°] is a state where it is difficult for the partner U2 to see the image displayed on the second display unit 12. When the display angle θ1 detected by the posture detection unit 40 exceeds a predetermined angle (step S20; YES), the display control unit 52 changes the display mode of the second display surface to two. Switching from the three-dimensional display mode to the three-dimensional display mode (step S30; display control step). Further, the display control unit 52 sets the display angle θ3 of the virtual image VI in the three-dimensional display mode to an angle corresponding to the display angle θ1 detected by the posture detection unit 40, and causes the second display unit 12 to display the virtual image VI. To finish the process. On the other hand, when the display angle detected by the posture detection unit 40 does not exceed the predetermined angle (step S20; NO), the display control unit 52 ends the process without switching the display mode.

  As described above, the electronic device 1 includes the display control unit 52 that switches the display mode of the second display unit 12 according to the attitude of the device itself. By providing the display control unit 52, the electronic device 1 displays the display mode of the second display unit 12 when the posture of the electronic device 1 is difficult for the partner U2 to view the image displayed on the second display unit 12. Can be switched. That is, the electronic device 1 can display an easy-to-see image for both the operator U1 and the partner U2.

[Second Embodiment]
Hereinafter, a second embodiment of the present invention will be described with reference to the drawings. In addition, about the structure similar to 1st Embodiment mentioned above, the same code | symbol is attached | subjected and description is abbreviate | omitted.
FIG. 7 is a configuration diagram showing an example of the configuration of the electronic device 1a according to the second embodiment of the present invention. The electronic device 1a is different from the electronic device 1 described above in that the electronic device 1a includes a reflection unit 13 that reflects an image displayed by the second display unit 12.

  The reflection unit 13 is configured by a mirror, a mirror-finished resin, or the like, and reflects an image displayed by the second display unit 12. The reflecting portion 13 is an example of a reflecting surface. Here, as shown in FIG. 7, the case where the electronic device 1a is placed with the angle formed by the desk TBL and the first display unit 11 as the angle θ1 will be described. The reflection unit 13 reflects the image displayed by the second display unit 12 in the direction of the reflection angle θ4 shown in FIG. The partner U2 can see the image (reflected image RI) reflected by the reflecting unit 13. Therefore, when the display angle θ2 is smaller than the threshold angle, the electronic device 1a can display an image that the partner U2 can easily see compared to the case where the partner U2 directly looks at the second display unit 12.

  In this case, the image (reflected image RI) reflected by the reflecting unit 13 is a mirror image of the image displayed by the second display unit 12. Therefore, it is preferable that the second display unit 12 can perform a mirror image display for displaying a mirror image on the reflection unit 13 and a non-mirror image display. In this case, the display control unit 52 switches between mirror image display and non-mirror image display according to the posture of the device itself. In this case, the mirror image display is an example of the first display mode, and the non-mirror image display is an example of the second display mode. Specifically, when the display control unit 52 determines that the display angle θ2 of the second display unit 12 is greater than or equal to a threshold angle (for example, 90 [°]), the display mode of the second display unit 12 is set to non-display. Switch to mirror image display mode. Accordingly, the partner U2 can directly view the image displayed on the second display unit 12. When the display control unit 52 determines that the display angle θ2 of the second display unit 12 is smaller than the threshold angle, the display control unit 52 switches the display mode of the second display unit 12 from the non-mirror image display mode to the mirror image display mode. In this way, the display control unit 52 makes the image (reflected image RI) of the second display unit 12 reflected by the reflecting unit 13 an erect image. As a result, the partner U2 can see the reflected image RI displayed at an easy-to-see angle compared to when the second display unit 12 is directly viewed. That is, the electronic device 1a can display an easy-to-see image for both the operator U1 and the partner U2.

  In addition, this reflection part 13 may be comprised so that it may fold to the 2nd display part 12 side centering | focusing on the axis | shaft of the Z-axis direction of hinge part H1. By configuring in this way, the electronic apparatus 1a can fold the reflecting portion 13 on the second display portion 12 side when the reflecting portion 13 is not used, and therefore, compared with the case where the reflecting portion 13 is not folded. The apparatus can be reduced in size. Furthermore, when the reflection part 13 is transparent, the image displayed on the second display part 12 can be transmitted even when the reflection part 13 is folded.

[Third Embodiment]
Hereinafter, a third embodiment of the present invention will be described with reference to the drawings. In addition, about the structure similar to each embodiment mentioned above, the same code | symbol is attached | subjected and description is abbreviate | omitted.
FIG. 8 is a configuration diagram illustrating an example of a configuration of an electronic apparatus 1b according to the third embodiment of the present invention. This electronic device 1b is different from the electronic device 1 described above in that it includes a projection unit 14 that projects an image displayed by the second display unit 12.

  The projection unit 14 is configured by a liquid crystal projector, for example, and projects an image displayed by the second display unit 12 onto the opposite surface of the first display unit 11. The partner U2 can see the image (projected image PI) projected by the projection unit 14. For this reason, when the display angle θ2 is smaller than the threshold angle, the electronic device 1b can display an image that the partner U2 can easily see compared to the case where the partner U2 directly looks at the second display unit 12.

  In this case, the display control unit 52 switches between the image display by the second display unit 12 and the image display by the projection of the projection unit 14 according to the posture of the own device. In this case, the display of the image by the second display unit 12 is an example of the first display mode, and the display of the image by the projection of the projection unit 14 is an example of the second display mode. Specifically, when the display control unit 52 determines that the display angle θ2 of the second display unit 12 is greater than or equal to a threshold angle (for example, 90 [°]), the display mode of the second display unit 12 is set to non-display. Switch to projection mode. Accordingly, the partner U2 can directly view the image displayed on the second display unit 12. When the display control unit 52 determines that the display angle θ2 of the second display unit 12 is smaller than the threshold angle, the display control unit 52 switches the display mode of the second display unit 12 from the non-projection mode to the projection mode. This projection mode is a display mode in which the projection unit 14 projects an image to be displayed on the second display unit 12 onto the projection surface (in this example, the surface of the desk TBL). Thereby, the other party U2 can see the image (projection image PI) projected on the surface of the desk TBL. That is, the partner U2 can see the projected image PI displayed at an easy-to-see angle compared to when the second display unit 12 is directly viewed. That is, the electronic device 1b can display an easy-to-see image for both the operator U1 and the partner U2.

  Note that the display control unit 52 may not display the image on the second display unit 12 when the projection unit 14 projects an image in the projection mode. Thereby, the electronic device 1b can reduce the power consumption for displaying an image on the 2nd display part 12. FIG.

The first display unit 11 displays the virtual image VI1 to the operator U1 with the display angle θ1. In addition, the second display unit 12 displays the virtual image VI2 on the opponent U2 with the display angle θ2. Here, the display angle θ1 is an angle at which the operator U1 can easily see the virtual image VI1. The display angle θ2 is an angle at which the counterpart U2 can easily see the virtual image VI2. In this case, the display control unit 52 switches the angle at which the virtual image VI1 is displayed by the first display unit 11 to the display angle θ1 that is easy for the operator U1 to view, according to the posture of the device itself. In addition, the display control unit 52 switches the angle at which the virtual image VI2 is displayed by the second display unit 12 to a display angle θ2 that is easy for the partner U2 to view, according to the posture of the device itself. Also with this configuration, the electronic device 1d can display an easy-to-see image for both the operator U1 and the partner U2.
