FIG.

  In order to improve user operability for switching display contents on a display surface, a display device according to the present disclosure includes a display unit having a display surface for displaying an image, and a normal line of the display surface as a rotation axis. The display surface is changeable between a first state and a second state having a rotation angle different from the first state by rotation of the display surface according to a user operation. When the display unit in the first state transitions to the second state, the rotation angle of the display surface changes until the transition to the second state among a plurality of images. An image to be displayed on the display surface is selected according to the mode, and the selected image is displayed on the display surface in the second state. And a control section for controlling the display unit so as to.

  As a result, the user performs a rotation operation with respect to the display device in which the manner of changing the rotation angle of the display surface is different from each other to change from the first state (for example, horizontal screen state) to the second state (for example, vertical screen state). By making the transition, the display content on the display surface in the second state can be easily switched. Therefore, the operability of the user related to the switching of display contents is improved by this display device.

  Here, for example, when the display surface in the first state transitions to the second state, the image selected by the control unit is changed from the first state to the second state by rotation in the first rotation direction. It may be different from when the first state is reached and when the second state is reached from the first state by rotation in the second rotational direction opposite to the first rotational direction.

  Thereby, the user can switch the display content on the display surface in the second state by an easy operation to change the rotation direction of counterclockwise or clockwise.

  Further, for example, the display surface is rectangular, the first state is a state where the longitudinal direction of the display surface is horizontal, and the second state is a rotation angle of the display surface in the first state. The rotation angle may be 90 degrees different from the rotation angle.

  Thereby, the user can easily switch the display content on the display screen in the vertical screen state according to the mode of the rotation operation.

  In addition, for example, when the display surface displaying the predetermined image in the first state transitions to the second state, the control unit displays the display from a plurality of images different from the predetermined image. An image to be displayed on the screen may be selected, and control may be performed so that the selected image is displayed on the display surface in the second state.

  As a result, the user can change the display content of the display screen in the horizontal screen state to another display content by changing the display content to the vertical screen state, and can select the other display content according to the mode of the rotation operation. Become.

  In addition, for example, the stand unit may be configured such that the display surface can be changed from the first state to a third state having a rotation angle different from any of the first state and the second state. The display device includes a sensor capable of identifying and detecting each of the first state, the second state, and the third state according to a rotation angle, and the second state is the first state. The third state is a state where the rotation angle is 90 degrees smaller than the rotation angle of the display surface in the first state, and the third state is a state where the rotation angle is 90 degrees less than the rotation angle of the display surface. The control unit selects an image to be displayed on the display surface based on a detection result of the sensor, and the display surface changes from the first state to the third state. If the transferred may be possible to control the image different from the image displayed on the display surface when a transition to the second state so as to be displayed on the display surface in the third state.

  Thereby, for example, if the display surface such as a vertical screen state is turned upside down, the user can make the display contents different from each other, and the display contents can be switched by an easy operation.

  In addition, for example, when the display surface transitions to the second state, the image selected by the control unit transitions to the second state in a mode in which the image is transitioned once from the state other than the second state to the second state. It may be different between when the transition is made and when the transition is made to the second state in such a manner that the transition is repeated twice from the second state to the second state.

  As a result, the user can switch the display content of the display surface in the second state depending on whether the operation of changing from the state other than the second state to the second state is performed once or twice.

  In addition, for example, the control unit distinguishes the aspect in which the rotation angle of the display surface has changed according to the number of times of repeating the transition from other than the second state to the second state, and according to the number of times. Control may be performed so that the selected image is displayed on the display surface in the second state.

  As a result, the user can switch the display content on the display surface in the second state according to the number of times of performing an operation of transitioning from the state other than the second state to the second state.

  Further, for example, when the number of times is a predetermined number of times, and when the number of times is the predetermined number of times + a predetermined value, the control unit selects a first image, and when the number of times is the predetermined number of times + 1, When the predetermined number of times + the predetermined value + 1, a second image different from the first image may be selected.

  Thereby, the user can switch the display content of the display surface of the second state in a certain repetition order according to the number of times of performing the operation for transition to the second state.

  Further, for example, the first image is composed of one image arranged in the entire area of the display surface, and the second image is arranged for each area obtained by dividing the entire area of the display surface into a plurality of areas. It may be composed of a plurality of images.

  Thereby, the user can switch the number of screen divisions (for example, the number of images to be displayed) of the display surface in the second state according to the number of times of performing the operation for transition to the second state.

  In addition, for example, when the display surface transitions to the second state, the control unit includes a first type image configured by one image arranged in an entire area of the display surface, and the display surface. An image to be displayed on the display surface in the second state may be selected from the second type images formed of a plurality of images arranged for each region obtained by dividing the entire region.

  Accordingly, the user can perform a rotation operation in which the display surface rotation angle changes in different manners, thereby dividing the display surface into a plurality of images and displaying an image in each divided region, or one image in the entire region. Can be switched.

  In addition, for example, the display device further includes an image sensor and a recording medium that records image selection information corresponding to each of a plurality of registered users, and the control unit further includes the display surface of the display device. In the case of transition to the second state, user authentication is performed based on the image captured by the image sensor, and the control unit performs the second operation based on the image selection information corresponding to the user who has succeeded in the user authentication. It is good also as selecting the image displayed on the said display surface in a state.

  Thereby, an image suitable for the user can be displayed for each user using the display device.

  In addition, for example, when the display surface is in the second state, the control unit further displays an image different from the image displayed on the display surface when a predetermined operation for contacting the display unit is performed. It is good also as controlling to display on the said display surface.

  As a result, the user can easily switch the display content on the display surface by performing a predetermined operation in contact with the display unit.

  In addition, for example, the display device further includes a receiving unit that receives operation information indicating a user operation on an information terminal having a touch pad from the information terminal, and the information terminal performs a predetermined first operation on the user. The first operation information corresponding to the touch operation is transmitted to the display device, and the second operation information corresponding to the touch operation is transmitted to the display device while the first operation is not performed. The control unit further displays on the display surface when the operation information is the first operation information and when the operation information is the second operation information when the reception unit receives the operation information. The display unit may be controlled so that different images are subjected to different changes.

  Thereby, the user can change the display content of the display surface to be different from each other by switching the operation on the information terminal.

  Further, for example, the information terminal includes a touch panel configured by superimposing the touch pad on an image display surface of the information terminal, and the first operation is a GUI (Graphical User Interface) displayed on the touch panel. The first operation information includes information for designating a position in accordance with the touch operation, and the control unit receives the first operation information when the receiving unit receives the first operation information. The position of the cursor displayed on the display surface is determined based on the position specified by the first operation information, and the cursor is displayed at the determined position superimposed on the image displayed on the display surface. The display unit is controlled to scroll the image displayed on the display surface when the receiving unit receives the second operation information. It is also possible to control the display unit to display Te.

  As a result, the user can move the cursor on the image displayed on the display surface and scroll the image displayed on the display surface by an operation that distinguishes between pressing and not pressing a specific button on the information terminal. It becomes possible to switch and instruct.

FIG. 3 shows the display device 1 viewed from the back side (that is, the back side of the display surface 11).

  The display device 1 includes a display unit 10 and a stand unit 20. The display device 1 is, for example, a portable image display device having portability, and the screen size is, for example, 43 inches. The display device 1 may be, for example, a liquid crystal display device or an organic EL (Electro-Luminescence) display device. The display device 1 is the same as the existing display device having a display surface rotation function, unless particularly described here.

  The display unit 10 includes a display surface 11 and a frame 12 that surrounds the display surface 11.

  The stand unit 20 includes a base 21 placed on a surface on which the display device 1 is installed, and a rotation mechanism unit 22 having a rotation mechanism that is mounted on the base 21 and rotatably supports the display unit 10 from the back surface. Prepare.

  The shape of the base 21 is not limited to that shown in FIG. 3 and may be any shape, for example, a shape having a plurality of legs. When the user applies a force to rotate the display unit 10 so as to rotate the display unit 10, the stand unit 20 including the rotation mechanism unit 22 has a horizontal screen state and a horizontal screen state according to the operation. Supports the display unit 10 so as to be freely changeable between vertical screen states at different rotation angles.

  The rotation mechanism unit 22 is configured to rotatably support the display unit 10 with a normal line of the display surface 11 (for example, a normal line passing through the center of the display surface 11 or a peripheral point thereof) as a rotation axis. The display surface 11 may be a flat surface or a curved surface. The rotation axis may be horizontal, or the rotation axis may be inclined several degrees from the horizontal plane so that the display surface 11 faces slightly upward. The rotation mechanism unit 22 may be configured to rotate the display surface 11 in accordance with a user operation (that is, an operation by the user) so as to be changed to a horizontal screen state or a vertical screen state. May be smaller than 360 degrees. For example, the rotatable angle range may be 90 degrees or 180 degrees. Further, since the display surface 11 changes between a vertical screen state and a horizontal screen state, the rotation mechanism unit 22 may support the display unit 10 so as to rotate in both directions, that is, in a rotatable manner. However, it may be supported so that it can only rotate. The stand unit 20 may include a speaker for outputting sound at a position that does not vary even when the display surface 11 rotates.

  The rotation detection sensor 60 is a sensor that notifies the control unit 40 of a change in the rotation angle of the display surface 11. For the rotation angle, the rotation detection sensor 60 has, for example, at least a vertical screen state (for example, a state where the rotation angle is 0 degree) and a horizontal screen state (for example, a state where the rotation angle is plus 90 degrees or minus 90 degrees), A state that is neither of the two is identified. The rotation detection sensor 60 may distinguish between a state where the rotation angle is plus 90 degrees and a state where the rotation angle is minus 90 degrees. As long as the rotation angle of the display surface 11 can be detected, the rotation detection sensor 60 may be arranged anywhere on the display device 1 or any sensor, for example, the display unit 10 that can rotate. Also, an orientation sensor, a gyro sensor, an acceleration sensor that can detect an angle with respect to the vertical direction by gravitational acceleration, and the like. In addition, the rotation detection sensor 60 is configured, for example, by arranging a magnet and a magnetic sensor in a portion that does not rotate with respect to the base 21 in the rotation mechanism unit 22 and a part of the display unit 10 that can rotate. Further, it may be configured to detect a vertical screen state, a horizontal screen state, and the like. The control unit 40 can know the manner in which the rotation angle of the display surface 11 has changed based on the rotation detection sensor 60. For example, the control unit 40 uses the rotation detection sensor 60 to rotate the display surface 11 clockwise from the horizontal screen state to the vertical screen state, and rotate counterclockwise from the horizontal screen state to the vertical screen. It is possible to distinguish when the state is reached. Thus, the control unit 40 makes the image to be displayed on the display screen 11 in the vertical screen state shifted clockwise and the image to be displayed on the display surface 11 in the vertical screen state shifted counterclockwise differ from each other. You can choose.

  The image sensor 70 is a camera for imaging, and can transmit the captured image to the control unit 40, and can store the captured image in the recording medium 50, for example. For example, the image sensor 70 is arranged so as to be able to image the front of the display surface 11, and can image a user who views the display surface 11 for user authentication under the control of the control unit 40. For example, the image sensor 70 may be disposed on the display unit 10 or may be disposed on the stand unit 20.

[1-2. Operation of display device]
Hereinafter, an operation related to a display control method of an image on the display surface 11 by the display device 1 having the above-described configuration will be described.

  6A to 6E are flowcharts illustrating an example of display control processing as a display control method in the display device 1. 6A to 6E show different examples. The display control process is a process realized by executing a control program on the processor in the control unit 40 of the display device 1. Hereinafter, the operation of the display device 1 will be described by sequentially using five examples in which the configuration and operation of the display device 1 are slightly different from each other.

[1-2-1. Operation example 1]
Hereinafter, an example of the display control process of the display device 1 will be described with reference to the flowchart of FIG. 6A. Here, the description will be made assuming that the image selection information illustrated in FIG. 5A is stored in the recording medium 50. For convenience, the horizontal state in which the rotation angle in the longitudinal direction of the display surface 11 is 0 degrees is a horizontal screen state, and the rotation angle is increased by left rotation, and the rotation angle is decreased by right rotation. However, the direction in which the rotation angle is 0 degree and the direction in which the rotation angle increases can be arbitrarily determined. In addition, the rotation mechanism of the rotation mechanism unit 22 is configured such that the display unit 10 is rotatable in the range where the rotation angle of the display surface 11 is at least −90 degrees to plus 90 degrees.

  First, the control unit 40 determines whether or not a transition to the horizontal screen state is detected using the rotation detection sensor 60 (step S11). In step S11, the control unit 40 determines whether or not the rotation angle of the display surface 11 measured by the rotation detection sensor 60 is 0 degrees.

  If it is determined in step S11 that a transition to the horizontal screen state has been detected, the control unit 40 determines an image determined in accordance with the horizontal screen state based on the image selection information (see FIG. 5A). That is, the TV broadcast image received by the receiving unit 30 is selected (step S12). Subsequently, the control unit 40 sets the display circuit of the receiving unit 30 and the display unit 10 so that the television broadcast image from the selected receiving unit 30 is transmitted to the display circuit of the display unit 10 and displayed on the display surface 11. Control (step S13).

  If it is determined in step S11 that the transition to the horizontal screen state has not been detected, the control unit 40 performs the transition to the vertical screen state by the left rotation based on the measurement result of the rotation detection sensor 60. It is determined whether or not it has been detected (step S14). In step S14, when the rotation angle of the display surface 11 measured by the rotation detection sensor 60 gradually increases from 0 degrees to +90 degrees, for example, the control unit 40 displays a vertical screen by left rotation. It is determined that the transition to the state has been detected.

  When it is determined in step S14 that the transition to the vertical screen state due to the left rotation is detected, the control unit 40 responds to the vertical screen state after the left rotation based on the image selection information (see FIG. 5A). Then, an image (that is, a camera image that is captured by the image sensor 70) is selected (step S15). Subsequently, the control unit 40 controls the selected camera image to be transmitted to the display circuit of the display device 1 and displayed on the display surface 11 (step S13). The control unit 40 may activate the image sensor 70 to start imaging when a camera image is selected as an image to be displayed on the display surface 11.

  If it is determined in step S14 that the transition to the vertical screen state due to the left rotation is not detected, the control unit 40 switches to the vertical screen state due to the right rotation based on the measurement result of the rotation detection sensor 60. It is determined whether or not a transition has been detected (step S16). In step S16, when the rotation angle of the display surface 11 measured by the rotation detection sensor 60 gradually decreases from 0 degrees to minus 90 degrees, for example, the control unit 40 displays the vertical screen by the right rotation. It is determined that the transition to the state has been detected.

  If it is determined in step S16 that the transition to the vertical screen state due to the right rotation has been detected, the control unit 40 responds to the vertical screen state after the right rotation based on the image selection information (see FIG. 5A). Then, the image (that is, the web page image received by the receiving unit 30) determined in this way is selected (step S17). Note that the control unit 40 is described in, for example, HTML (HyperText Markup Language) by causing the receiving unit 30 to access specific web page information on the network based on the URL specified in the image selection information. The web page image as the content of the web page specified based on the web page information thus obtained can be acquired. Subsequently, the control unit 40 controls the selected web page image to be transmitted to the display circuit of the display device 1 and displayed on the display surface 11 (step S13).

  Note that the display unit 10 may be configured to be rotatable by the rotation mechanism of the rotation mechanism unit 22 such that the display surface 11 can be rotated over 360 degrees or more. In this case, in step S14, when the rotation angle reaches plus 90 degrees or minus 90 degrees (for example, equivalent to plus 270 degrees) due to a gradually increasing change, the transition to the vertical screen state due to the left rotation is detected. It will be judged as a thing. Similarly, in step S16, when the rotation angle reaches plus 90 degrees (for example, equivalent to minus 270 degrees) or minus 90 degrees due to a gradually decreasing change, a transition to the vertical screen state due to right rotation is detected. It will be judged as a thing.

  As shown in FIG. 6A, since the determination process (step S11, step S14 or step S16) in the display control process described above is repeatedly performed, when the display surface 11 is rotated by a user operation, the display content of the display surface 11 is rotated according to the rotation. Switches. As described above, when the display surface 11 displaying the television broadcast image in the horizontal screen state transitions to the vertical screen state, the control unit 40 differs from the television broadcast image depending on the rotation direction. An image to be displayed on the display surface 11 is selected from among the images, and the selected image is controlled to be displayed on the display surface 11 in the horizontal screen state. Accordingly, the user can display different screens depending on whether the screen is turned to the vertical screen state by the left rotation or the vertical screen state by the right rotation, and the user can display the image displayed on the display surface 11 with an easy operation. Can be switched.

[1-2-2. Operation example 2]
Hereinafter, an example of the display control process of the display device 1 will be described with reference to the flowchart of FIG. 6B. Here, the description will be made assuming that the image selection information illustrated in FIG. 5B is stored in the recording medium 50. For convenience, it is assumed that a horizontal state in which the rotation angle in the longitudinal direction of the display surface 11 is 0 degrees is a horizontal screen state. In addition, the rotation mechanism of the rotation mechanism unit 22 is configured such that the display unit 10 can rotate in a range where the rotation angle of the display surface 11 is at least −90 degrees to +90 degrees. For example, the display unit 10 may be configured to be rotatable so that the display surface 11 can be rotated over 360 degrees or more.

  Steps S21 to S23 are the same as steps S11 to S13 shown in FIG. 6A, and description thereof will be omitted as appropriate.

  First, the control unit 40 determines whether or not a transition to a horizontal screen state has been detected (step S21).

  If it is determined in step S21 that the transition to the horizontal screen state has been detected, the control unit 40 is determined corresponding to the horizontal screen state based on the image selection information (see FIG. 5B). The television broadcast image received by the receiving unit 30 is selected (step S22). Subsequently, the control unit 40 controls the display circuit and the like of the display unit 10 so that the selected television broadcast image is transmitted to the display circuit of the display unit 10 and displayed on the display surface 11 (step S23).

  When it is determined in step S21 that the transition to the horizontal screen state is not detected, the control unit 40 determines that the vertical screen state has a rotation angle of plus 90 degrees based on the measurement result of the rotation detection sensor 60. It is determined whether or not a transition to is detected (step S24).

  If it is determined in step S24 that a transition to a vertical screen state with a rotation angle of plus 90 degrees has been detected, the control unit 40, based on the image selection information (see FIG. 5B), has a portrait orientation of plus 90 degrees. A camera image picked up by the image sensor 70 determined in accordance with the screen state is selected (step S25). Subsequently, the control unit 40 performs control so that the selected camera image is transmitted to the display circuit of the display unit 10 and displayed on the display surface 11 (step S23).

  If it is determined in step S24 that the transition to the vertical screen state where the rotation angle is plus 90 degrees is not detected, the control unit 40 determines that the rotation angle is based on the measurement result of the rotation detection sensor 60. It is determined whether or not a transition to a vertical screen state of minus 90 degrees has been detected (step S26).

  If it is determined in step S26 that a transition to a vertical screen state with a rotation angle of minus 90 degrees has been detected, the control unit 40 performs a minus 90 degree portrait based on the image selection information (see FIG. 5B). Select an image that is determined according to the screen state (that is, a two-divided screen image that is an image formed by dividing the display surface 11 into two parts and arranging a television broadcast image and a camera image in each divided area). (Step S27). Subsequently, the control unit 40 controls the selected two-divided screen image to be transmitted to the display circuit of the display device 1 and displayed on the display surface 11 (step S23).

  As shown in FIG. 6B, the determination process (step S21, step S24, or step S26) in the display control process described above is repeatedly performed. Therefore, when the display surface 11 is rotated by a user operation, the display content on the display surface 11 is rotated according to the rotation. Switches. Thereby, the user can display different screens depending on the rotation angle even in the same vertical screen state by rotating the display unit 10 so that the display surface 11 is at a specific angle. It is possible to switch the display content of the display surface 11 with a simple operation.

[1-2-3. Operation example 3]
Hereinafter, an example of the display control process of the display device 1 will be described with reference to the flowchart of FIG. 6C. Here, description will be made assuming that the image selection information illustrated in FIG. 5C is stored in the recording medium 50. In addition, it is assumed that the horizontal state in which the rotation angle in the longitudinal direction of the display surface 11 is 0 degrees is the horizontal screen state, and the state in which the rotation angle is plus 90 degrees is the vertical screen state. In addition, the rotation mechanism of the rotation mechanism unit 22 is configured such that the display unit 10 can rotate within a range in which the rotation angle of the display surface 11 is at least 0 degrees to plus 90 degrees. For example, the display surface 11 may be configured to be rotatable within an angle range exceeding 90 degrees, and a state where the rotation angle is plus 90 degrees and a state where the rotation angle is minus 90 degrees may be the vertical screen state.

  Steps S31, S32, and S34 are the same as steps S11, S12, and S13 shown in FIG. 6A, respectively, and description thereof will be omitted as appropriate.

  First, the control unit 40 determines whether or not a transition to a horizontal screen state has been detected (step S31).

  If it is determined in step S31 that the transition to the horizontal screen state has been detected, the control unit 40 is determined corresponding to the horizontal screen state based on the image selection information (see FIG. 5C). A television broadcast image is selected (step S32). Then, the control unit 40 resets the value of the variable R indicating the number of transitions to the vertical screen state (hereinafter referred to as “the number of transitions R to the vertical screen state”) used in the display control process to 0 (step S33). ). Subsequently, the control unit 40 transmits the selected television broadcast image from the receiving unit 30 to the display circuit of the display unit 10 and displays the image on the display surface 11. Control (step S34).

  Further, when it is determined in step S31 that the transition to the horizontal screen state is not detected, the control unit 40 changes from the vertical screen state to the vertical screen state based on the measurement result of the rotation detection sensor 60. It is determined whether or not a transition is detected (step S35). In step S35, when the rotation angle of the display surface 11 measured by the rotation detection sensor 60 reaches, for example, plus 70 degrees to plus 90 degrees, the control unit 40 is not in a vertical screen state (for example, an oblique screen). It is determined that the transition from the screen state) to the vertical screen state is detected.

  If it is determined in step S35 that a transition from a state other than the vertical screen state to the vertical screen state has been detected, the control unit 40 increases the number of transitions R to the vertical screen state by 1 (step S36). If it is determined in step S35 that the transition from the state other than the vertical screen state to the vertical screen state is not detected, the control unit 40 returns to the determination in step S31 without switching the display content on the display surface 11.

  Following the processing in step S36, the control unit 40 selects one of the plurality of images whose rotation order is determined in the image selection information (see FIG. 5C) according to the number of transitions R to the vertical screen state. An image is selected (step S37). In step S37, as an example, since the number of states to be rotated is three (see FIG. 5C), if the number of transitions R to the vertical screen state is 3n + 1 (where n is an integer of 0 or more), control is performed. The unit 40 selects an image corresponding to the vertical screen state (1) in FIG. 5C (that is, an image composed of one web page image without a screen division). If the number of transitions R to the vertical screen state is 3n + 2 (where n is an integer equal to or greater than 0), the control unit 40 displays an image corresponding to the vertical screen state (2) in FIG. It is assumed that an image composed of two web page images arranged in each divided area divided into two at a division ratio of 2 is selected. If the number of transitions R to the vertical screen state is 3n + 3 (where n is an integer equal to or greater than 0), the control unit 40 displays an image corresponding to the vertical screen state (3) in FIG. It is assumed that an image composed of three web page images respectively arranged in each divided area divided into three at a 1: 1 division ratio is selected.

  After the image selection in step S37, the control unit 40 switches the display circuit of the receiving unit 30 and the display unit 10 so that the selected image is transmitted to the display circuit of the display device 1 and displayed on the display surface 11. Control (step S34).

  As shown in FIG. 6C, since the determination process (step S31 or step S35) in the display control process described above is repeatedly performed, when the display surface 11 is rotated by a user operation, the display content of the display surface 11 is switched according to the rotation.

  This switching of display contents will be described below using the screen transition example shown in FIG.

  First, when the screen is changed to the horizontal screen state, a television broadcast image 101 (for example, a video of a sports broadcast program) is displayed on the display surface 11. For example, when the screen transitions to the vertical screen state for the first time, one web page image 102 is displayed on the entire display surface 11 in the vertical screen state. When the user performs an operation to temporarily change from a vertical screen state (for example, a rotation angle of 90 degrees) to a state other than the vertical screen state (for example, a rotation angle of 70 degrees) and return to the vertical screen state again. The vertical display screen 11 is divided into two, and two different web page images 102a and 103 are displayed. Further, when the user performs an operation of changing from the vertical screen state to a state other than the vertical screen state and returning to the vertical screen state again, the display screen 11 in the vertical screen state is divided into three, and three different webs are mutually separated. A page image 102a, a web page image 103a, and a web page image 104 are displayed. Further, when the user performs an operation of once changing from the vertical screen state to a state other than the vertical screen state and returning to the vertical screen state again, one web page image 102 is again displayed on the entire display surface 11 in the vertical screen state. Will be displayed. As a result, the user can rotate the display screen 11 in the vertical screen state a little (that is, make the longitudinal direction of the rectangular display surface 11 slightly slant from the vertical) and then return the display content to the display surface 11 by an easy operation. Can be switched.

[1-2-4. Operation example 4]
Hereinafter, an example of the display control process of the display device 1 will be described with reference to the flowchart of FIG. 6D. In the operation example 3 described above, the display content of the display surface 11 is changed based on the number of transitions R from the vertical screen state to the vertical screen state, whereas in this operation example, the impact on the display unit 10 is changed. Based on the number of impact detections S, which is the number of detections, the display content of the display surface 11 changes. Here, as in the operation example 3, it is assumed that the image selection information illustrated in FIG. 5C is stored in the recording medium 50. Further, it is assumed that the display unit 10 is provided with an impact detection sensor for detecting an impact, and the control unit 40 detects that the user has performed an operation of tapping the display unit 10 with the impact detection sensor. Shall. The impact detection sensor can be, for example, a vibration sensor, an acceleration sensor, or the like. In addition, it is assumed that the horizontal state in which the rotation angle in the longitudinal direction of the display surface 11 is 0 degrees is the horizontal screen state, and the state in which the rotation angle is plus 90 degrees is the vertical screen state.

  Steps S41 to S43 are the same as steps S11 to S13 shown in FIG. 6A, and description thereof will be omitted as appropriate.

  First, the control unit 40 determines whether or not a transition to a horizontal screen state has been detected (step S41).

  If it is determined in step S41 that the transition to the horizontal screen state has been detected, the control unit 40 is determined corresponding to the horizontal screen state based on the image selection information (see FIG. 5C). A television broadcast image is selected (step S42). And the control part 40 transmits the display circuit of the receiving part 30 and the display part 10 so that the image of the selected television broadcast is transmitted to the display circuit of the display part 10 from the receiving part 30, and is displayed on the display surface 11. Control (step S43).

  If it is determined in step S41 that the transition to the horizontal screen state has not been detected, the control unit 40 changes from a state other than the vertical screen state to the vertical screen state based on the measurement result of the rotation detection sensor 60. It is determined whether or not a transition is detected (step S44). In step S44, the control unit 40 switches from the vertical screen state to the vertical screen state when the rotation angle of the display surface 11 measured by the rotation detection sensor 60 is, for example, 0 degrees to plus 90 degrees. It is determined that a transition has been detected.

  If it is determined in step S44 that a transition from a state other than the vertical screen state to the vertical screen state has been detected, the control unit 40 uses a variable S () indicating the number of times the impact on the display unit 10 is detected, which is used in the display control process. Hereinafter, the value of “the number of times of impact detection S” is reset to 0 (step S45).

  After step S45, or when it is determined in step S44 that a transition from a state other than the vertical screen state to the vertical screen state is not detected (for example, when the vertical screen state is maintained), the control unit 40 Determines whether or not an impact has been detected when the display surface 11 is in the vertical screen state based on the measurement result of the impact detection sensor (step S46).

  If it is determined in step S46 that an impact has been detected, the control unit 40 increases the impact detection count S by 1 (step S47). If it is determined in step S46 that an impact has not been detected, the control unit 40 does not switch the display content on the display surface 11 and returns to the determination in step S41.

  Subsequent to the processing in step S47, the control unit 40 selects one image according to the number of times of impact detection S among a plurality of images in which the rotation order is determined in the image selection information (see FIG. 5C). (Step S48). In step S48, as an example, since the number of states to be rotated is three (see FIG. 5C), if the number of impact detections S is 3n + 1 (where n is an integer equal to or greater than 0), the control unit 40 Assume that an image corresponding to the vertical screen state (2) in FIG. 5C (that is, an image that is a set of two web page images arranged by dividing the screen into two) is selected. If the number of shock detections S is 3n + 2 (where n is an integer equal to or greater than 0), the control unit 40 arranges the image corresponding to the vertical screen state (3) in FIG. Assume that an image that is a set of three web page images) is selected. If the number of shock detections S is 3n (where n is an integer equal to or greater than 0), the control unit 40 displays an image corresponding to the vertical screen state (1) in FIG. 5C (that is, one web page without screen division). Image).

  After the image selection in step S48, the control unit 40 displays the display circuit of the receiving unit 30 and the display unit 10 so that the selected image is transmitted to the display circuit of the display device 1 and displayed on the display surface 11. Control (step S43).

  As shown in FIG. 6D, the determination process (step S41, step S44 or step S46) in the display control process described above is repeatedly performed. Therefore, when the display surface 11 is rotated by a user operation, the display content on the display surface 11 according to the rotation. The display content of the display surface 11 is switched according to the number of times of impact detection in the vertical screen state. For example, when a transition is first made to the vertical screen state, one web page image is displayed on the entire display surface 11 in the vertical screen state. Then, when the user performs an operation of tapping the display unit 10 once, the display screen 11 in the vertical screen state is divided into two, and two different web page images are displayed. Furthermore, when the user performs an operation of tapping the display unit 10 once, the display screen 11 in the vertical screen state is divided into three, and three different web page images are displayed. Furthermore, when the user performs an operation of tapping the display unit 10 once, one web page image is displayed again on the entire display surface 11 in the vertical screen state. As a result, the user can switch the display content of the display surface 11 by an easy operation of hitting the display unit 10 in the vertical screen state.

[1-2-5. Operation Example 5]
Hereinafter, an example of the display control process of the display device 1 will be described with reference to the flowchart of FIG. 6E. Here, it is assumed that the image selection information for each of a plurality of users including user A and user B as illustrated in FIG. 5D is stored in the recording medium 50. Further, it is assumed that the horizontal state in which the rotation angle in the longitudinal direction of the display surface 11 is 0 degrees is the horizontal screen state, and the state in which the rotation angle is plus 90 degrees or minus 90 degrees is the vertical screen state.

  The control unit 40 performs user authentication processing (step S51). As the user authentication process, for example, the control unit 40 obtains a camera image that is an image of the front side of the display surface 11 from the image sensor 70 and records it on the recording medium 50 (see FIG. 4). With reference to the information, image processing for user authentication is performed on the acquired camera image. For example, the control unit 40 refers to the feature information related to the feature of the face image for each registered user included in the user authentication information, and collates with the feature of the face image extracted from the acquired camera image. The user authentication is performed by detecting the registered user in the camera image.

  Next, the control unit 40 determines whether or not the display surface 11 is in the horizontal screen state based on the measurement result of the rotation detection sensor 60 (step S52).

  When it is determined in step S52 that the screen is in the horizontal screen state, the control unit 40 is determined corresponding to the horizontal screen state with reference to the authenticated user image selection information (see FIG. 5D). An image is selected (step S53). For example, in a situation where the user A is located in front of the display surface 11, the user A is authenticated by the user authentication process in step S51. In step S53, the user A's image selection information 90a is referred to, and the television broadcast Images are selected.

  Subsequent to step S53, the control unit 40 controls the receiving unit 30 and the display circuit of the display unit 10 so that the selected television broadcast image is transmitted to the display circuit of the display unit 10 and displayed on the display surface 11. (Step S54).

  If it is determined in step S52 that the screen is not in the horizontal screen state, the control unit 40 determines whether the rotation angle is plus 90 degrees or minus 90 degrees based on the measurement result of the rotation detection sensor 60. It is determined whether or not the display surface 11 is in a vertical screen state (step S55).

  If it is determined in step S55 that the screen is in the vertical screen state, the control unit 40 is determined corresponding to the vertical screen state with reference to the authenticated user image selection information (see FIG. 5D). An image is selected (step S56). For example, in a situation where the user A is authenticated, in step S53, the image selection information 90a of the user A is referred to, and the camera image being captured by the image sensor 70 is selected as an image corresponding to the vertical screen state. Further, for example, in a situation where the user B is located in front of the display surface 11, the user B is authenticated by the user authentication processing in step S51, and in step S53, the image selection information 90b of the user B is referred to. A web page image is selected as an image corresponding to the vertical screen state.

  Subsequent to step S56, the control unit 40 controls the display circuit and the like of the display unit 10 so that the selected image is transmitted to the display circuit of the display unit 10 and displayed on the display surface 11 (step S54).

  If it is determined in step S55 that the control unit 40 is not in the vertical screen state, the process returns to the determination process in step S51 without switching the display content on the display surface 11.

  As shown in FIG. 6E, the user authentication process (step S51) and the determination process (step S52 or step S55) in the above-described display control process are repeatedly performed. Therefore, by appropriately determining image selection information for each user. Depending on the user using the display device 1, the display content of the display surface 11 in the horizontal screen state or the vertical screen state is appropriately switched. Regarding the switching of the display contents, an example of screen transition is shown in FIG. In a situation where the user A stands in front of the display surface 11 in the vertical screen state, a camera image 105 that is captured based on the image selection information 90a of the user A and is captured on the display surface is displayed on the display surface. The user A can use the display device 1 as an appearance (stand mirror). In addition, it is possible to specify that the camera image is corrected so as to be a mirror image that is reversed left and right in the image selection information of the user A, and the control unit 40 controls the display of the camera image according to the specification related to the correction of the image. Also good. When the user B stands in front of the display screen 11 in the vertical screen state, the web page image 102 selected based on the image selection information 90b of the user B is displayed on the display screen.

In the display device 1 that can selectively display a plurality of images (for example, a plurality of images having different input sources), a user operation for designating an image to be displayed on the display device 1 is easy. .

  In the display control method in the display device 1 described above, the display surface 11 is moved from the first state (for example, a horizontal screen state or a state where the rotation angle is 70 degrees or the like) by the rotation of the display surface 11 according to a user operation. When a transition is made to a second state (for example, a vertical screen state) having a rotation angle different from that of the first state, the rotation angle of the display surface 11 changes until the transition to the second state among a plurality of images. A selection step (for example, steps S14 to S17) for selecting an image to be displayed on the display surface 11 in accordance with the mode, and a control for controlling the display unit 10 to display the selected image on the display surface 11 in the second state. Step (for example, step S13). The selection step is, for example, processing by the image selection unit 42 in the control unit 40, and the control step is, for example, processing by the display control unit 41 in the control unit 40. Thereby, the user can switch the display content of the display surface 11 in a 2nd state with the various aspects of rotation operation.

  In addition, as a vertical screen state of the display surface 11, for example, only a case where a specific short side of the rectangular display surface 11 is arranged at the top may be treated as the second state. Even in the case of being arranged, it may be handled as the second state. When only the case where a specific short side is arranged at the top is handled as the second state, the case where the opposite short side is arranged at the top is handled as the third state, and the third state and the second state are selected in the selection step. Different images may be selected. Further, in the case where any one of the two short sides is arranged at the upper part and handled as the second state, if the first state is a state where the longitudinal direction of the display surface 11 is horizontal, the second state Is a state in which the rotation angle is 90 degrees different from the rotation angle of the display surface 11 in the first state.

  Further, according to the above-described operation example 3, when the display surface 11 transitions to the second state (for example, the vertical screen state), the image selected by the control unit 40 is changed from the non-second state to the second state. There may be a difference between when the transition is made to the second state in a mode in which the transition is made twice, and when the transition is made to the second state in a mode where the transition is repeated twice from the state other than the second state. In this case, the first state (for example, the horizontal screen state or the state where the screen having a rotation angle of 70 degrees or the like is oblique) can be handled as other than the second state. In addition, the control unit 40 distinguishes the aspect in which the rotation angle of the display surface 11 has changed according to the number of times the transition from the state other than the second state to the second state is repeated, and selects the image selected according to the number of times. It is displayed on the display surface 11 in two states. The number of repetitions may be, for example, the number of times within a fixed time, or may be the number of times with no time limit (for example, the number of times since the start of the display device 1). According to the operation example 3, when the number of repetitions is a predetermined number (for example, 1 time) (that is, once in this example), and when the number of repetitions is the predetermined number + a predetermined value (for example, 3). (I.e., 4 times in this example), the first image is selected, the number of repetitions is the predetermined number +1 (i.e., 2 times in this example), and When the predetermined number of times + predetermined value + 1 (that is, in this example, 5 times), the second image different from the first image is selected to be rotated. For example, the first image is composed of one image arranged in the entire area of the display surface 11, and the second image is a plurality of images arranged for each area obtained by dividing the entire area of the display surface 11 into a plurality of areas. Consists of images.

  The operability for the user of switching the display contents on the display surface 11 in the display device 1 is, for example, an operation in which the transition between the screen oblique state and the vertical screen state is relatively easy. It ’s good. Moreover, since the display content of the display surface 11 (for example, the number of screen divisions of the display surface 11) is switched by rotation, it is highly convenient for the user who wants to check each display content.

(Embodiment 2)
In the present embodiment, a display system including the display device 1 described in the first embodiment will be described with reference to the drawings. Note that the display device 1 in the present embodiment is the same as the display device 1 shown in the first embodiment with respect to points not particularly shown here.

[2-1. System configuration]
The display system according to the present embodiment includes the display device 1 (see FIGS. 1 to 4) shown in the first embodiment and the information terminal 200. The information terminal 200 is a terminal device that operates the display device 1 and includes, for example, a touch panel configured by superimposing a touch pad on the surface of the display (that is, the image display surface). FIG. 9 shows an example of the information terminal 200, and shows an example of the screen (that is, an example of display contents on the touch panel of the information terminal 200). Note that the touch pad is a pointing device that includes, for example, a flat sensor and receives an operation for designating a position by detecting a change in the position touched with the finger with respect to the sensor.

  The information terminal 200 is a terminal device having a function capable of transmitting operation information corresponding to a user operation to the display device 1. Even if the information terminal 200 is a dedicated device for operating the display device 1, the information terminal 200 is used for operating the display device 1. A device having a function other than the function may also be used. The information terminal 200 may be, for example, a smartphone as shown in FIG. 9, a tablet, a notebook PC (Personal Computer), a remote controller (remote controller), or the like. For example, the information terminal 200 is a computer including a communication interface, an input / output interface, a memory, a processor, and the like. By installing an application on a smartphone, a tablet, or the like, and causing the processor such as the smartphone or tablet to execute the application, the smartphone, the tablet, or the like may function as the information terminal 200 for operating the display device 1. Good.

  In the screen example of FIG. 9, the information terminal 200 displays a button 202 as a GUI (Graphical User Interface) element on the touch panel 201. The button 202 is a button for switching to the mouse mode when pressed. The mouse mode here is a mode in which the touch operation on the touch panel 201 gives the same operability to the display surface of the display device 1 as the operation with the mouse.

  The information terminal 200 can exchange information with the display device 1 using, for example, short-range wireless communication. The information terminal 200 has a function of transmitting the first operation information to the display device 1 in response to the user's touch operation on the touch panel 201 when the button 202 is pressed by the user. In addition to the identification information for distinguishing from the second operation information, the first operation information includes, for example, information indicating the touch operation mode and the touch position as the content corresponding to the touch operation. The touch operation mode represents, for example, a type of touch operation that identifies a tap, a long tap, an upward swipe, a downward swipe, a right swipe, a left swipe, and the like. In addition, you may include a flick, a pinch in, a pinch out, etc. as a classification of a touch operation aspect.

  The information terminal 200 has a function of transmitting the second operation information to the display device 1 in response to the user's touch operation on the touch panel 201 when the button 202 is not pressed by the user. The second operation information includes, for example, a touch operation mode as the content corresponding to the touch operation, in addition to the identification information for distinguishing from the first operation information.

  Note that the display device 1 according to the present embodiment, in addition to the functions of the display device 1 described in the first embodiment, cooperates with the information terminal 200 in response to a user operation on the information terminal 200. It has a function that can change the display contents, and a control process is performed for this function. Further, in display device 1 in the present embodiment, receiving unit 30 further receives operation information (that is, first operation information or second operation information) transmitted from information terminal 200 and notifies control unit 40. The control unit 40 determines the display content on the display surface 11 in accordance with the operation information.

[2-2. Operation]
Hereinafter, a cooperative operation between the information terminal 200 and the display device 1 will be described.

[2-2-1. Information terminal operation]
FIG. 10 is a flowchart showing an operation information transmission process as an operation example of the information terminal 200 described above. This operation information transmission process is performed, for example, when an application for operating the display device 1 is activated on the information terminal 200.

  The specifications of the above-mentioned application that cooperates with the display device 1 are as follows. When the user performs a touch operation by depressing the button 202, for example, the movement of the cursor with respect to the display device 1 and the contents of the cursor position in the same manner as a mouse movement or a click by a mouse operation as a pointing device. Selection and the like are possible. In addition, when the user performs a swipe as a touch operation without pressing the button 202, the display content on the display surface 11 can be scrolled with respect to the display device 1.

  Hereinafter, the operation of the information terminal 200 will be described with reference to FIG.

  The information terminal 200 displays an operation screen (that is, an operation GUI image) including the button 202 on the touch panel (step S61).

  The information terminal 200 determines whether or not the button 202 is being pressed (step S62). When a touch operation is performed on a portion other than the button 202 while the button 202 is being pressed, the touch operation mode and the touch position are determined according to the touch operation. The first operation information shown is transmitted to the display device 1 (step S63), and the process returns to the determination in step S62 again.

  In addition, when a touch operation is performed on a portion other than the button 202 when the button 202 is not being pressed, the information terminal 200 transmits second operation information indicating a touch operation mode to the display device 1 according to the touch operation. (Step S64), and the process returns to the determination in Step S62.

[2-2-2. Operation of display device]
FIG. 11 is a flowchart illustrating an example of a control process of the display device 1 that cooperates with the information terminal 200. Hereinafter, the control process of the display apparatus 1 will be described with reference to FIG.

  The control unit 40 of the display device 1 performs display control processing (step S71). This display control process is the process shown in the first embodiment (for example, the process shown in any of FIGS. 6A to 6E), but loops only within the display control process (that is, the processing procedure is repeated). ), And repeatedly including the display control process and the subsequent process such as step S72.

  In step S72, the control unit 40 of the display device 1 determines whether or not the receiving unit 30 has received operation information from the information terminal 200. If not received, the processing in steps S73 to S75 is skipped. Then, the process returns to the display control process (step S71).

  When it is determined in step S72 that the receiving unit 30 has received the operation information from the information terminal 200, the control unit 40 determines whether the operation information is the first operation information (step S73).

  If it is determined in step S73 that the received operation information is the first operation information, the control unit 40 determines the position of the cursor to be displayed on the display surface 11 based on the touch position indicated by the first operation information. And the display circuit of the display unit 10 is controlled so as to display the cursor superimposed on the image being displayed on the display surface 11 (step S74). The control unit 40 determines the position of the cursor from the touch position by, for example, coordinate conversion processing between the coordinate system of the coordinates detected on the touch panel of the information terminal 200 and the coordinate system of the pixels on the display surface 11. FIG. 12 shows an example of the display surface 11 on which the cursor is displayed. In this example, the display screen 11 in the vertical screen state is divided into two vertically and a web page image 102a and a web page image 103 relating to different websites are displayed. The user presses the button 202 on the touch panel of the information terminal 200 and performs a touch operation to move the cursor 111 displayed superimposed on the web page image 103, for example, in the desired web page image 103. This part can be selected.

  Following step S74, the control unit 40 executes control corresponding to the position of the cursor according to the touch operation mode indicated by the first operation information (step S75), and returns to the display control process (step S71). The control corresponding to the cursor position is, for example, selection of display contents at the cursor position. More specifically, information for a hyperlink is displayed at the cursor position during the display of the web page image. For example, the web page image of the link destination is displayed. Note that the control corresponding to the position of the cursor is the same as the control corresponding to an operation such as click or double click when the pointing device is a mouse. As an example, the control unit 40 performs the same control as a click when the touch operation mode is a tap, and performs the same control as a double click when the touch operation mode is a long tap.

  When it is determined in step S73 that the received operation information is not the first operation information (that is, the second operation information), the control unit 40 displays the display according to the touch operation mode indicated by the second operation information. The display circuit of the display unit 10 is controlled so as to scroll and display the image being displayed on the surface 11 (step S76), and the process returns to the display control process (step S71). For example, if the touch operation mode is an upward swipe, the control unit 40 controls to display an image being displayed on the display surface 11 by scrolling a predetermined amount upward, and the touch operation mode is a downward swipe. For example, the display surface 11 is controlled to be scrolled and displayed by a predetermined amount. The predetermined amount is, for example, a length that is half the size of the display surface 11, and may be other lengths.

  Note that the above-described example is merely an example, and a mode (for example, rotation, enlargement / reduction, etc.) of changing an image being displayed on the display surface 11 with respect to various touch operation modes is determined in any way. Good.

  As described above, when the receiving unit 30 receives the operation information, the control unit 40 of the display device 1 determines whether the operation information is the first operation information or the second operation information on the display surface 11. The display unit 10 is controlled so as to apply different changes (for example, changes such as cursor movement and scrolling) to the displayed image.

[2-3. effect]
According to such a system, the user can switch the display content of the display surface 11 by an operation of rotating the display surface 11, and further, the display content of the display surface 11 can be easily operated by operating the information terminal 200. Can be changed.

(Other embodiments, etc.)
As described above, Embodiments 1 and 2 have been described as examples of the technology disclosed in the present application. However, the technology in the present disclosure is not limited to this, and can also be applied to embodiments in which changes, replacements, additions, omissions, and the like are appropriately performed.

  In the embodiment described above, the shape of the display surface 11 is a rectangle, but the shape is not necessarily limited to a rectangle, and may be any shape such as a square, an ellipse, or a star. Further, the frame 12 surrounding the display surface 11 in the display unit 10 may be omitted.

  In the above-described embodiment, the display device 1 having a screen size of 43 inches or the like is shown as an example, but the screen size may be larger or smaller than 43 inches.

  Moreover, in the above-mentioned embodiment, the stand part 20 showed the example which has the rotation mechanism part 22 pivotally supported so that the display part 10 can be rotated. As another example in the small display device 1 having a relatively small screen size, the stand unit 20 does not have the rotation mechanism unit 22, and the display surface 11 has a rotation angle with respect to one normal line of the surface. In any state of a different first state (for example, a horizontal screen state) and a second state (for example, a vertical screen state), it may be a pedestal that can support the display unit 10 while maintaining each state. .

  Further, in the above-described embodiment, the control unit 40 determines that the display surface 11 in the first state (for example, a horizontal screen state or an oblique screen state with a rotation angle of 70 degrees or the like) is in a second state (for example, a vertical screen state). Screen state), the image to be displayed on the display surface 11 is selected according to the mode in which the rotation angle of the display surface 11 has changed until the transition to the second state, and selected. Control for displaying the image on the display surface 11 in the second state is performed. As the selection of the image by the control unit 40, the first type image composed of one image arranged in the entire area of the display surface 11 and the respective areas obtained by dividing the entire area of the display surface 11 into a plurality of areas are arranged. It may be selected from the second type image composed of a plurality of images. In other words, the control unit 40 may select the number of screen divisions of the display surface 11 in the second state according to the change in the rotation angle until the transition to the second state. In this case, in accordance with the rotation operation, an image configured by arranging the number of images corresponding to the selected number of screen divisions in the divided areas is displayed on the display surface 11.

  In the user authentication shown in the above-described embodiment (operation example 5), the display surface 11 is in one of the first state (for example, the horizontal screen state) or the second state (for example, the vertical screen state) by rotating. It may be performed only in cases. When the user authentication is performed when the display surface 11 is in the vertical screen state, the control unit 40 displays the display surface 11 in the vertical screen state based on at least the image selection information corresponding to the user who has succeeded in the user authentication. The image to be displayed is selected, and control for displaying the selected image is performed. Note that user authentication is performed based on user authentication information including information of each registered user. However, when the user to be authenticated can be authenticated as one of the registered users. Treated as successful authentication, otherwise treated as authentication failure. If the authentication fails, an image may be displayed based on the default image selection information not associated with the user on the display surface 11, or any other image may be displayed. The image may not be displayed.

  Further, the image selection information recorded on the recording medium 50 shown in the above-described embodiment may be set by the user via the information terminal 200, for example. A setting content is specified and transmitted in response to an input from a terminal device (for example, the information terminal 200) that receives the setting content, and the receiving unit 30 of the display device 1 receives the setting content. It is good also as updating.

  In the above-described embodiment, the image selection information (FIGS. 5A to 5D) is an image to be displayed when the display surface 11 is in the first state (in this example, the horizontal screen state) related to the rotation angle. And an image to be displayed in the second state (vertical screen state in this example). However, when it is predetermined to display a specific image on the display surface 11 in the first state (for example, horizontal screen state), the image selection information includes, for example, the second state (for example, vertical screen state). Only information useful for selecting an image to be displayed on the display surface 11 (information on a plurality of images as options) may be included.

  In addition, as the image to be displayed in the above-described image selection information (see, for example, FIG. 5C, etc.), a multi-split screen image composed of a plurality of split screens is defined, and each of the plurality of split regions is defined. Television broadcast images may be defined as all or a part of the images to be displayed (for example, images displayed in the uppermost divided area), and should be displayed in a plurality of divided areas. As each image, a television broadcast image received through a different channel may be determined. Depending on the setting contents of the image selection information, for example, when the display surface 11 is in a vertical screen state in response to a specific rotation operation, the image of the TV broadcast and the web page image are mixed to split the display surface. 11 can be displayed. Further, the image selection information is displayed as a multi-divided screen image related to a plurality of divided areas obtained by dividing the screen into a plurality of divided areas, when the display surface 11 is in a horizontal screen state according to a specific rotation operation. You may decide to. In addition, when defining a multi-divided screen image having a plurality of divided areas obtained by dividing the screen as the setting contents of the image selection information, the input sources of the images that are the display contents of the respective divided areas are different from each other. Can be anything.

  In the above-described embodiment (operation example 4), the impact detection sensor detects that the user has performed an operation of tapping the display unit 10, and the display content on the display surface 11 is switched according to the operation. Although an example has been shown, such an operation is not limited to the tapping operation, and may be an operation of stroking the surface of the display surface 11 or the frame 12. In other words, when the display surface is in the second state (for example, a vertical screen state), the control unit 40 is different from the image displayed on the display surface 11 when a predetermined operation for touching the display unit 10 is performed. May be controlled to be displayed on the display surface 11. In this case, the display device 1 includes a sensor that detects the predetermined operation. The display device 1 may select different images depending on whether the user strokes the frame 12 upward or downward, and displays the selected images on the display surface 11. In the case where the display device 1 includes a speaker, when the user strokes the frame 12 upward, the sound output from the speaker (for example, when a television broadcast image is displayed on the display surface 11, the television broadcast It is also possible to increase the volume of the sound or the like that constitutes the program together with the image, and decrease the volume by stroking downward. Further, the display device 1 may include an audio input device, and the control unit 40 may display content on the display surface in the vertical screen state according to the content input by voice when the display surface is in the vertical screen state. May be selected.

  In the above-described embodiment, the information terminal 200 displays the button 202 on the touch panel 201. The information terminal 200 may be configured such that the user can arbitrarily change the display position of the button 202. In the information terminal 200, the button 202 described above may be replaced with a button physically provided in the information terminal 200. Further, in the above-described embodiment, the information terminal 200 has been described as an example in which the touch pad is configured as a part of the touch panel 201. However, the information terminal 200 may have only a touch pad without having a display surface, or may have a touch pad separately from the display surface. Further, the information terminal 200 transmits information indicating the input character to the display device 1 according to the user's character input operation, and the display device 1 uses the character as a search keyword according to the information indicating the character. The result of the search process performed by the search engine may be displayed on the display surface 11.

  In the above-described embodiment, it has been shown that the display surface 11 may be rotated by a motor drive or the like according to a user input operation. However, for example, the information terminal 200 including an acceleration sensor that can detect gravitational acceleration and the like. However, when it is rotated by the user, information indicating the rotation angle or the like is transmitted to the display device 1, and the display device 1 rotates the display surface 11 in the same manner as the information terminal 200 by driving the motor according to the information indicating the rotation angle or the like. It is also possible to make it.

  In the above-described embodiment, the display device 1 receives a television broadcast and displays a television broadcast image, a function of accessing a website and displaying a web page image (that is, a web browser function), a camera An example of displaying an image from a plurality of input sources having a function of displaying an image has been shown. However, the display device 1 does not necessarily need to receive a television broadcast, does not necessarily have a web browser function, and does not necessarily include a camera. That is, the number of image input sources that can be displayed by the display device 1 is not limited.

  Further, in the above-described embodiment, the image to be displayed on the display surface 11 selected by the control unit 40 is one overall image composed of images arranged for each divided region obtained by dividing the display surface 11 into a plurality of regions. An example that is an image is shown. In addition, the control unit 40 may select two or more images as images to be selected in the selection step (for example, steps S15, S17, S25, S27, S37, etc.). In this case, the control unit 40 may control display so that two or more selected images are displayed on the display surface 11 in an arbitrary arrangement, or display two or more selected images. Display control may be performed so that the images are sequentially displayed on the surface 11 by time division.

  Moreover, the function sharing of the display control unit 41 and the image selection unit 42 in the control unit 40 described above can be arbitrarily changed, and the respective units may be integrated.

  In the above-described embodiment, an example in which the display apparatus 1 performs user authentication by image processing using a user's face image is shown. However, an authentication technique using a password, a voiceprint, other biometric information, or the like input by the user is used. User authentication may be performed by using it. Moreover, the display apparatus 1 does not need to perform user authentication.

  Further, the execution order of the various processes (for example, the procedures shown in FIGS. 6A to 6E or FIG. 11) in the display device 1 or the processes (for example, the procedures shown in FIG. 10) in the information terminal 200 is not necessarily described above.
