The above is the description of the second panel 102.

  Hereinafter, the details of the wires 103 to 106 that are connecting means for connecting the relative arrangement of the first panel 101 and the second panel 102 in the present embodiment in a changeable manner will be described. The wires 103 to 106 are linear connection means formed of synthetic fiber or a metal material, and connect the first panel 101 and the second panel 102 in a foldable manner.

  Each of the wires 103 to 106 has elasticity in the linear direction and flexibility in the bending direction. Moreover, the both ends of each wire are connection means in a shape in which the ends are not joined to each other. That is, the wires 103 to 106 of the present embodiment have a non-loop shape.

  The wires 103 to 106 described above are fixed to the fixing portions in a state where both ends are pulled so that tension is generated in the wire direction of the wires. For example, in the case of the wire 103, the display device 100 is fixed to the fixed portion 101e1 and the fixed portion 102f1 so that at least the wire 103 does not bend in each of the expanded state and the folded state (stored state or double-sided state). .

  The wires 103 to 106 are subjected to external force applied when the user changes (expands or folds) the state of the display device 100. In order to prevent the wire from falling off the groove due to the external force, it is desirable to increase the tension of the wire and reduce the looseness. Specifically, in order to prevent the wire from being broken by the external force described above, it is desirable to reduce the tension of the wire to a predetermined value or less calculated from the tensile strength of the wire. That is, it is necessary to keep the tension of each wire within a desirable range in order to ensure reliability in consideration of dropping of the wire from the groove and breakage of the wire. However, the tension of each wire varies from the design value depending on the processing accuracy and assembly accuracy of the parts.

  Therefore, in the present embodiment, the above-described problem is solved by employing one independent member as the wires 103 to 106 and providing the above-described tension changing unit 115 on the first panel 101.

  The tension changing unit 115 of this embodiment will be described. Each fixing portion has a fixing pin (not shown) around which a wire can be wound and a rotating mechanism (not shown) for rotating the fixing pin.

  In addition, a hole is provided at each position of the first panel 101 and the second panel 102 corresponding to each of the fixing portions described above. The rotation mechanism described above is provided inside the hole. The fixing pin described above is inserted into the hole with the wire wound around a predetermined amount, and is engaged with the rotation mechanism and the fixing pin inside the hole.

  And according to the instruction | indication of the 1st control part 110, when the rotation mechanism mentioned above rotates each fixing pin, the winding amount of the wire by each fixing pin is controlled. With this configuration, the tension of the wires 103 to 106 is changed by a fixing pin and a rotation mechanism provided in each fixing portion. That is, in this embodiment, each fixing part including the fixing pin and the rotation mechanism described above corresponds to the tension changing unit 115.

  In addition, the groove part for winding up a wire is formed in the circumference | surroundings of the fixing pin mentioned above. Then, the outer diameter of the fixing pin is set slightly larger than the inner diameter of the hole. In this state, the inside of the hole portion and the outside of the fixing pin slide with each other while generating a predetermined frictional force, so that the fixing pin can be prevented from falling out of the hole portion.

  With the configuration described above, the display device 100 of this embodiment can independently adjust the tension of each wire. Therefore, it can prevent that each wire falls out from the corresponding groove part, or is damaged.

  Moreover, the display apparatus 100 of this embodiment can change the tension | tensile_strength of each wire according to the kind of image displayed on each display part by the structure mentioned above. That is, the display device 100 of the present embodiment can change the maintenance force for maintaining the relative arrangement of the panels by changing the tension of each wire. Details of this will be described later.

  In addition, even if the tension | tensile_strength change part 115 adjusts the tension | tensile_strength of the wire 103, the tension | tensile_strength of the other wires 104-106 does not change. That is, in the display device 100 of this embodiment, only the tension of the wire that needs to be adjusted can be adjusted independently. The above is the description of the wires 103 to 106.

  In the present embodiment, when the display device 100 is in a horizontally developed state, the groove portions and the fixed portions of the first panel 101 and the second panel 102 are lines having the sides 2 and 4 as center lines. It is provided at a position having a symmetrical relationship. Further, when the display device 100 is in the vertically developed state, the groove portions and the fixing portions of the first panel 101 and the second panel 102 have a line-symmetric relationship with the side lines 1 and 3 being the center line. Provided in position. Details of this will be described later.

  Further, in the display device 100 of the present embodiment, each wire is fixed, and the fixing pin and the rotation mechanism described above are used as a fixing portion that can change the tension of each wire. However, the display device 100 is not limited thereto. It is not something. For example, as long as the tension of each wire can be changed independently, a configuration other than those described above may be adopted as each fixing portion. For example, a method can be employed in which the end of the wire can be hooked on a hook or the like provided on each panel, and the amount of wire pulling by the hook is controlled.

  As described above, as the state of the display device 100 is changed (folded) from the vertically expanded state to the double-sided state, the positions of the first panel 101 and the second panel 102 that support each wire change. To do. And according to the position which supports a wire changing, the position where each wire cross | intersects from the position between the A surface and B surface of the 1st panel 101 and the 2nd panel 102 to the B surface side. And migrate. With this configuration, the state of the display device 100 can be changed (folded) without the wires falling out of the corresponding grooves. When the state of the display device 100 is changed (deployed) from the double-sided state to the vertically developed state, the wires operate in the reverse order to the above-described movement.

  With the configuration described above, the display device 100 according to the present embodiment can easily perform a deformation operation between the five states of the horizontally expanded state, the double-sided state, the stored state A, the stored state B, and the vertically expanded state. Therefore, the display device 100 of the present embodiment can change the relative arrangement of the first panel 101 and the second panel 102 each provided with a display unit into a plurality of states. In particular, in the first panel 101 and the second panel 102, the relative positions of the first panel 101 and the second panel 102 are such that the sides positioned on the extension line are different (adjacent sides are different). The arrangement can be changed.

  Therefore, when the display device 100 according to the present embodiment displays a single image on the display unit 101a and the display unit 102a in a divided manner, the display device 100 of each panel is configured according to the size of the single image and the type of shooting. The relative arrangement can be freely changed.

  For example, the ratio of two orthogonal sides (for example, the long side and the short side) of the display image displayed on the entire display device 100 is a ratio frequently used for a photograph (or an image sensor) such as 3: 2 or 16: 9. If there is, the state of the display device 100 is changed to the vertically expanded state. Further, the ratio of two orthogonal sides of the display image displayed on the entire display device 100 is a horizontally long ratio (for example, a ratio of 2: 1 or more) such as a scope size frequently used for movies or a so-called panoramic image. If there is, the state of the display device 100 is changed to the horizontally expanded state.

  As described above, the display device 100 according to the present embodiment can change the relative arrangement of the panels in accordance with the ratio (aspect ratio) of two sides of the display image that are orthogonal to each other by the user. Therefore, when a single image is divided and displayed on each display unit, the image can be displayed as large as possible on each display unit. In particular, when the display device 100 is applied to an imaging device such as a digital camera, the image can be displayed as large as possible in accordance with various images with different sizes (ratio of each side) acquired by the imaging device. it can.

  Here, a display size of an image (display image) on the first panel 101 and the second panel 102 of the display device 100 will be described.

  First, when the display device 100 is in the double-sided state (FIG. 5C), the display size of the display image on the display unit 101a and the display unit 102a is Wd, the length in the direction parallel to the long side of each housing. The length in the direction parallel to the short side is Hd.

  When the display device 100 is in the horizontally developed state (FIG. 5B), the display area of the entire display device 100 is an area obtained by adding the display unit 101a and the display unit 102a. Therefore, when the display device 100 is in the horizontally developed state, the above-described region can be regarded as the display region of the display device 100 and a display image can be displayed in the display region. In this case, the size of the display area is a width 2Wd and a height Hd.

  Similarly, even when the display device 100 is in the vertically expanded state (FIG. 5D), the region where the display unit 101a and the display unit 102a are added is regarded as the display region of the entire display device 100, and in this case The size of the display area is a width Wd and a height 2Hd.

  That is, the display device 100 of the present embodiment can make the display area in the unfolded state about twice as large as the display area in the double-sided state. Conversely, the display device 100 can make the display area in the double-sided state approximately half the area of the display area in the unfolded state. As described above, the display device 100 according to the present embodiment can reduce the size of the device itself and the size of the display area according to the state, so that the display area on the same plane can be enlarged while improving portability. can do.

  As described above, the display device 100 according to the present embodiment can be changed to a plurality of states such as a storage state (A, B), a horizontally expanded state, a double-sided state, and a vertically expanded state. In particular, in the first panel 101 and the second panel 102, the relative arrangement of the first panel 101 and the second panel 102 can be changed so that the sides positioned on the extension line are different from each other.

  With this configuration, when the display device 100 according to the present embodiment splits and displays a single image on the display unit 101a and the display unit 102a, the display device 100 according to the aspect ratio or the like of the image desired to be displayed The general arrangement can be changed freely.

  Here, a case where the display device 100 is applied as a display unit of a digital camera (hereinafter simply referred to as a camera) 1 as an imaging device will be described with reference to FIG. FIG. 9 is a diagram illustrating the camera 1 according to the first embodiment of the present invention.

The operation button group 12 can be used for changing or adjusting various parameters at the time of imaging, changing an image at the time of image reproduction, and the like. For example, in a state where the above-described operation screen is displayed on each display unit, the user can set various parameters related to imaging while confirming on the operation screen by operating the operation button group 12.

  The display mode includes an enlarged display mode in which a divided image obtained by dividing a single image including a subject image into a plurality of display images is displayed on each display unit, and an image including the subject image is displayed on one display unit. The normal display mode for displaying the operation screen on the other display unit can be set.

  In the above-described enlarged display mode, when the display device is in the unfolded state, the divided images displayed on the display units are combined and displayed as one image, and the image is displayed on a single display unit. In comparison, a single image can be enlarged and displayed.

  In the normal display mode, an image including a subject image may be displayed on each display unit independently. In addition to the display mode described above, a configuration in which a mode in which the display unit 101a and the display unit 102a are turned off may be set.

FIG. 10B is a diagram for explaining a case where an operation screen is displayed on the display unit 101a and a through image is displayed on the display unit 102a (normal display mode) in the horizontal development state of the display device 100.

  As illustrated in FIG. 10A, when the display device 100 is in the unfolded state, two images are displayed on the display unit 101a and the display unit 102a. One display image is displayed by combining the display units.

  In such a state, an external force is applied to the display device 100 by hitting one panel to the outside, and the relative arrangement of the first panel 101 and the second panel 102 is different from the user's intention. If it changes to a state, a user will feel uncomfortable.

  In particular, when each panel of the display device 100 is a touch panel corresponding to a so-called touch operation, various settings related to the display device 100 are performed by the user's touch operation on each panel. In this case, if the relative arrangement of the first panel 101 and the second panel 102 changes according to the user's touch operation, the user feels uncomfortable.

  Therefore, when the captured image is divided into a plurality of images (divided images) and displayed on each display unit, the relative arrangement of the first panel 101 and the second panel 102 is suppressed in order to suppress a sense of discomfort given to the user. It is desirable that is difficult to change. That is, when the type of display image displayed on the display device 100 is a divided image, a configuration that can easily maintain the unfolded state of each panel is desirable.

  The above problem can be solved by increasing the maintenance force for maintaining the relative arrangement of the first panel 101 and the second panel 102 when displaying a divided image on each display unit.

  On the other hand, when the type of the display image displayed on the display device 100 is not a divided image, it is desirable that the relative arrangement of the first panel 101 and the second panel 102 be easily changed. The details will be described below.

  For example, in the case where the same captured image is displayed independently on the display unit of each panel, when the subject is imaged by the camera 1, the captured image is taken from the subject side to be imaged by directing one panel toward the imaging direction. Can be confirmed.

  In addition, when performing so-called self-timer shooting or self-taking, it is desirable that the user can take an image while confirming the captured image. In this case, since the user can adjust the composition of the camera 1 at the time of imaging while confirming the captured image by directing the display unit toward the imaging direction with the captured image displayed on the display unit, the image intended by the user Can be obtained. Therefore, it is desirable that the position of the panel with the display unit facing the imaging direction is easily changed with the composition change of the camera 1.

  As described above, when different types of images are displayed on each display unit, the relative arrangement of the first panel 101 and the second panel 102 is improved in order to improve the operability of the display device 100 by the user. It is desirable to be easy to change. That is, when the types of display images to be displayed on the display device 100 are different images, it is desirable to have a configuration in which the development state of each panel can be easily changed.

  However, as described above, it is difficult for the user to change the relative arrangement of the panels by strengthening the maintenance force between the panels. Therefore, the operability of the display device 100 by the user is the maintenance force between the panels. It is lower than when weakening.

  In order to solve this problem, when different types of display images are displayed on each display unit, the ability to maintain the relative arrangement of the first panel 101 and the second panel 102 may be weakened. desirable.

  Note that the type of display image described above in the present embodiment refers to whether or not the display image displayed on the display unit 101a and the display unit 102a is an image obtained by dividing a single image (divided image) as described above. It is about. That is, in this embodiment, the display image is divided into a case where a divided image obtained by dividing a captured image is displayed on each display unit, and a case where the same captured image is displayed on both the display unit 101a and the display unit 102a. The type shall be different.

  As described above, in a display device that can change the relative arrangement of the panels, the strength that is desirable as the maintenance force between the panels varies depending on the type of image displayed on each display unit. That is, when displaying a display image on each display unit, it is difficult to solve various problems depending on the type of display image if the relative arrangement of the panels is always maintained with a constant maintenance force. is there.

  Therefore, the display device 100 according to the present embodiment changes the force for maintaining the unfolded state of the first panel 101 and the second panel 102 according to the type of display image displayed on the display unit 101a and the display unit 102a. This solves the above-mentioned problem. Hereinafter, the details will be described with reference to FIG.

  FIG. 11 is a flowchart for explaining the maintenance force changing process of the display device 100 according to the first embodiment of the display device embodying the present invention. Hereinafter, the first control unit 110 will be abbreviated as the control unit 110 unless otherwise specified. Information used for each process described below is recorded in a memory (not shown) of the display device and is appropriately read out by the control unit 110.

  When the maintenance force change process is started in response to the power switch of the camera 1 being turned on, the control unit 110 determines the type of display image in step S1101.

  In the present embodiment, the display image is displayed on each display unit at the same time as the power is turned on based on the setting of the display device 100 when the power is turned on. However, the present invention is not limited to this. For example, the display image may be displayed on each display unit simultaneously with the end of the maintenance force changing process that is executed for the first time after the power is turned on. That is, the display image in step S1101 is image data of a display image to be displayed next on each display unit, and the image data is read from a memory (not shown) and the process of step S1101 is executed. There may be.

  Next, in step S1102, the control unit 110 determines whether the display image of each display unit is a divided image based on the type of display image determined in step S1101.

  When the control unit 110 determines that the display image is a divided image (YES in step S1102), the process proceeds to step S1103. When it is determined that the display image is not a divided image (NO in step S1102), the process proceeds to step S1106.

  Next, in step S1103, the control unit 110 detects the state of the display device 100 based on output signals from the sensors 113a, 113b, 123a, and 123b. Specifically, the control unit 110 detects the state of the display device 100 by detecting the conduction state between the sensors.

  Note that output signals from the sensors 123a and 123b are transmitted from the second control unit 120 to the first control unit 110 via the first communication unit 112 and the second communication unit 122. .

  FIG. 12 is a diagram illustrating a state detection method for the display device 100 according to the first embodiment of the present invention. As illustrated in FIG. 12, when the control unit (arrangement detection unit) 110 detects that the sensor 113a and the sensor 123a are in a conductive state, the control unit (arrangement detection unit) 110 indicates that the display device 100 is in the horizontally developed state. To detect. In addition, when it is detected that the sensor 113b and the sensor 123b are in a conductive state, the control unit 110 detects that the display device 100 is in a vertically developed state. Moreover, the control part 110 detects that the display apparatus 100 is a folding state, when a conduction | electrical_connection state is not detected in any sensor.

  Next, in step S1104, the control unit 110 determines whether or not the current state of the display device 100 is the unfolded state (horizontal unfolded state or vertically unfolded state) based on the information regarding the state of the display device 100 detected in step S1103. Determine whether.

  When the control unit 110 determines that the current state of the display device 100 is not the unfolded state (NO in step S1104), the process proceeds to step S1106. Details of this will be described later.

  When the control unit 110 determines that the current state of the display device 100 is the unfolded state (YES in step S1104), the process proceeds to step S1105. In step S1105, the control unit 110 instructs the tension changing unit 115 to change (set) the tension of the wires 103 to 106 to the first tension. In step S1106, the control unit 110 instructs the tension changing unit 115 to change (set) the tension of the wires 103 to 106 to the second tension.

  Here, the first tension described above is a force in which the tension of each wire is stronger (larger) than the second tension. Therefore, in the display device 100 of this embodiment, the tension of each wire is stronger (larger) when the display image type is a divided image than when the display image type is not a divided image. That is, the power of maintaining the relative arrangement of the first panel 101 and the second panel 102 is greater when the display image type is a divided image than when the display image type is not a divided image. Strong (big).

  In addition, as a 1st tension | tensile_strength, when a user's hand touches, when the display apparatus 100 collides with the exterior of the camera 1, etc., when the force added to the display apparatus 100 is a comparatively small force, between each panel. It is desirable that the force does not change the state. For example, when the display unit of each panel is the touch panel described above, it is desirable that the force is such that the relative arrangement of the panels is not changed by the user's touch operation. Further, the second tension may be a force that does not cause the user to feel unnatural when the user changes the arrangement of the panels.

  With the configuration described above, the display device 100 of the present embodiment can easily maintain the relative arrangement of the panels when the type of display image is an image obtained by dividing a single image into a plurality of images. Giving the user a sense of incongruity can be suppressed.

  Further, the display device 100 of the present embodiment makes it easy to change the relative arrangement of the panels when the type of display image is not an image obtained by dividing a single image into a plurality of images. The operability can be improved. Therefore, in this embodiment, it is possible to improve the usability of the display device 100 that can change the relative arrangement of a plurality of housings each having a display unit.

  Note that the display device 100 may be configured to determine whether or not to change the tension of each wire in accordance with the type of display image. That is, the configuration may be such that the tension of each wire is changed when the type of display image is a divided image, and the tension of each wire is not changed when the type of display image is not a divided image.

  At this time, the tension of each wire when the type of display image is a divided image is stronger (larger) than the tension of each wire when the type of display image is not a divided image.

  In the present embodiment, even if the type of the display image is a divided image, if the determination in step S1104 determines that the configuration of the display device 100 is not in the unfolded state, the tension of each wire is set to the second tension. It is the structure which changes to tension. That is, the display device 100 according to the present embodiment has a configuration in which the tension of the wires 103 to 106 is changed according to whether or not the state of the display device 100 is an unfolded state.

  With this configuration, the relative arrangement of the panels can be easily maintained only when the display device 100 is in the unfolded state and the display image type is an image obtained by dividing a single image into a plurality of images. That is, it is possible to suppress a decrease in the operability of the display device 100 by the user in the transition state or the folded state of the display device 100. In addition, the structure which changes the tension | tensile_strength of each wire only according to the kind of display image, without performing the process of step S1103-S1104 may be sufficient.

  In steps S1105 and S1106, the maintenance force change process is terminated in response to the completion of the change in the tension of each wire. In the present embodiment, the control unit 110 is configured to start the next maintenance force change process in response to detecting that the display image has been changed or the state of the display device 100 has been changed.

  Therefore, when a change in the display image or a change in the state of the display device 100 as described above is detected during the current maintenance force change process, the current maintenance force change process is stopped and the next process is started. The above is the maintenance force changing process of the present embodiment.

  In the present embodiment, the configuration in which the tension of all the wires 103 to 106 is changed according to the type of display image has been described, but the present invention is not limited to this. For example, a configuration in which any tension of the wires 103 to 106 is changed according to the type of display image may be used.

  In the present embodiment, the force for maintaining the relative arrangement of the first panel 101 and the second panel 102 is changed by changing the tension of each wire according to the type of display image. However, the present invention is not limited to this.

  For example, a plurality of magnets are provided at positions corresponding to each of the first panel 101 and the second panel 102, and the force (coupling force) acting on the plurality of magnets is changed according to the type of display image. Such a configuration may be adopted. The details will be described below with reference to FIGS.

  FIG. 13 is a three-view diagram of a display device 200 that is a modification of the display device according to the first embodiment of the present invention. In addition, in order to simplify description, in FIG. 13, each wire, a fixing | fixed part, a groove part, and a corner | angular part are not shown in figure. FIG. 14 is a block diagram illustratively showing a display device 200 that is a modification of the display device according to the first embodiment of the present invention.

  The difference between the display device 100 and the display device 200 described above is that each panel is provided with a current changing unit instead of the tension changing unit 115, the first panel 101 is provided with magnets 215a and 215b, and the second panel 102 is provided with a current changing unit. This is the point where magnets 225a and 225b are provided. 13 and 14, the same components as those of the display device 100 in the display device 200 are denoted by the same reference numerals as those of the display device 100, and description thereof is omitted.

  As illustrated in FIG. 13A, the magnet 215 a and the magnet 225 a can be magnetically attracted when the display device 200 is in the laterally developed state. Note that. In the lateral development state of the display device 200, the magnet 215b and the magnet 225b are separated from each other.

  Further, as illustrated in FIG. 13B, the magnet 215b and the magnet 225b can be magnetically attracted in the vertically expanded state of the display device 200. Note that. In the vertically developed state of the display device 200, the magnet 215a and the magnet 225a are separated from each other.

  Each of the magnets 215a, 215b, 225a, 225b includes an electromagnet that is magnetized when a current is applied (second connecting means).

  The magnets 215a and 225a, and the magnets 215b and 225b are different from the wires 103 to 106 in that the connection is released by changing the relative arrangement of the first panel 101 and the second panel 102. Means.

  Specifically, when the display device 200 is in the horizontally developed state, the magnets 215a and 225a are coupled (coupled), and the coupling (coupled) between the magnet 215b and the magnet 225b is released. Further, when the display device 200 is in the vertically developed state, the coupling (coupling) between the magnets 215a and 225a is released, and the magnets 215b and the magnets 225b are coupled (coupled).

  Magnet 215a and magnet 225a are set so that their poles are different from each other by changing the direction of the applied current. The same applies to the magnet 215b and the magnet 225b.

  As shown in FIG. 14, the first current control unit 215 controls the value of current applied to the magnets 215a and 215b and the direction of the current so that the strength of the magnetic force and the magnetic pole of the magnets 215a and 215b can be changed. Means. The second current control unit 225 is a control unit that can control the current value applied to the magnets 225a and 225b and the direction of the current, and can change the strength of the magnetic force and the magnetic pole of the magnets 225a and 225b.

  As described above, the display device 200 can change the force (coupling force) at which the magnet 215a and the magnet 225a are magnetically attracted and coupled to each other. The same applies to the magnet 215b and the magnet 225b.

  Therefore, in the maintenance force changing process, instead of changing the tension of the wires 103 to 106, the display described above is performed even if the current applied to each magnet is changed to change the force with which each magnet is coupled. The same effect as the device 100 can be obtained. That is, the display device of the present embodiment is configured to change the force for maintaining the relative arrangement of the panels by changing the coupling force between the corresponding magnets according to the type of display image. It may be. In this case, the first current control unit 215 and the second current control unit 225 correspond to changing means for changing the maintenance force.

  Note that the display device 200 may be configured not to change the current value to be applied but to control whether or not to apply a current. That is, a configuration may be adopted in which current is applied to each magnet when the type of display image is a divided image, and no current is applied to each magnet when the type of display image is not a divided image.

  Even in the configuration of the display device 200 described above, when the type of display image is an image obtained by dividing a single image into a plurality of images, the relative arrangement of the panels can be easily maintained. Giving a sense of incongruity can be suppressed. In addition, when the type of display image is not an image obtained by dividing a single image into a plurality of images, the relative arrangement of the panels can be easily changed, so that the operability of the display device can be improved for the user. it can.

  The rotation axis of the hinge part 400 is parallel to the short side (for example, side 2) of the first panel 101 and the short side (for example, side 4) of the second panel 102. Therefore, the relative arrangement of the first panel 101 and the second panel 102 can be changed by the operation of the hinge part 400 so that the side 2 and the side 4 are adjacent to each other. That is, the display device 300 according to the present embodiment can change the relative arrangement of the panels so that the side 3 of the second panel 102 is positioned on the extension line of the side 1 of the first panel 101. It is.

  In the display device 300 according to the present embodiment, the torque changing unit 315 changes the resistance force of the hinge unit 400 according to the type of display image determined by the display image determining unit 114. Specifically, the resistance of the hinge unit 400 when the display image type is a divided image is made stronger (larger) than when the display image type is not a divided image.

  That is, the display device 300 makes the force for maintaining the relative arrangement of the panels when the display image type is a divided image stronger than when the display image type is not a divided image.

  With this configuration, the display device 300 of the present embodiment makes it easy for the user to maintain the relative arrangement of the panels when the type of display image is an image obtained by dividing a single image into a plurality of images.
