Description

[Technical Field]

[0001] The present disclosure relates to a display method and a display system. [Background technology]

[0002] The map search device described in Patent Document 1 displays maps and the like on a display device (see Patent Document 1). The technology described in Patent Document 1 includes a map database that stores map data including road maps, and the map data has coordinate information. Furthermore, in the technology described in Patent Document 1, based on the latitude / longitude information of the imaging point, the captured image data is stored in the captured image database with coordinate information that is associated with the coordinate information in the map database through a matching process, and images of marks indicating the imaging point and imaging direction are stored in the imaging point mark database with coordinate information that is associated with the coordinate information in the map database.

[0003] Furthermore, in the technology described in Patent Document 1, a map based on the read map data and image capturing point marks are displayed on a display device. In addition, in the technology described in Patent Document 1, by selecting one of a plurality of image capturing point marks displayed on a display device, an image captured based on captured image data corresponding to the selected image capturing point mark is displayed on the display device. Furthermore, in the technology described in Patent Document 1, the captured image is displayed on the display device in a state where it is superimposed on a map or in a state where it is aligned with the map.

[0004] In this way, the technology described in Patent Document 1 discloses that when map data and captured image data that are associated by coordinate information are displayed on a single display device, the captured image data can be displayed overlaid on the map data, or the map data and captured image data can be displayed side by side.

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2009-70228 Summary of the Invention [Problem to be solved by the invention]

[0006] However, in the technology described in Patent Document 1, sufficient consideration has not been given to the case where display is performed using a plurality of display devices. For example, consider a case where map data and captured image data associated by coordinate information are displayed on a plurality of display devices, each equipped with a display screen. In this case, if the technology described in Patent Document 1 is applied, an image in which the captured image data is displayed superimposed on the map data, or an image in which the map data and the captured image data are displayed side by side, would be displayed on each of the plurality of display devices, making it impossible to effectively utilize the display areas of the plurality of display devices. [Means for solving the problem]

[0035] FIG. 5 is a diagram showing an example of a schematic configuration of the server device D1 according to the embodiment. The server device D1 includes an input unit 141, an output unit 142, a communication unit 143, a storage unit 144, a control unit 145, and a service providing processing unit 146.

[0036] The input unit 141 inputs information according to an operation performed by an operator (not shown). The output unit 142 outputs information by display output, audio output, or the like. The communication unit 143 communicates with an external device, which in this embodiment is the first display device A1. The storage unit 144 stores various types of information.

[0037] The control unit 145 performs various processes and controls in the server device D1. In this embodiment, the server device D1 is configured using a computer. The control unit 145 includes a processor such as a CPU, and performs various processes and controls by executing predetermined programs using the processor. The service providing processing unit 146 performs processing for providing a predetermined service. In this embodiment, the service providing processing unit 146 is controlled by the control unit 145, for example, to perform various types of processing.

[0038] In this embodiment, the service providing processing unit 146 of the server device D1 performs a service of providing predetermined information. The information is stored, for example, in the storage unit 144. As another example, the information may be stored in a database or the like (not shown) that is provided externally to the server device D1, and in this case, the server device D1 acquires the information from the database or the like. In this embodiment, the information provided by the server device D1 is map information and aerial photograph information. The information provided by the server device D1 is not particularly limited, and any other information may be used.

[0039] In this embodiment, the server device D1 is operated by an operator, but the server device D1 may be remotely operated by an operator, for example. As another example, the server device D1 may automatically perform a predetermined process without being operated by an operator.

[0040] The map information and aerial photograph information provided by the server device D1 will be described with reference to FIGS. 6A and 6B. In this embodiment, the first display device A1 performs a process of acquiring desired map information from the server device D1 and a process of acquiring desired aerial photograph information from the server device D1. For convenience of explanation, the process of acquiring map information and the process of acquiring aerial photograph information will be explained separately here, but the processes of acquiring these two types of information may be realized by common request information, for example.

[0041] FIG. 6A is a diagram showing an example of information on the A-th content 211A stored in the server device D1 according to the embodiment. The information of the A-th content 211A is, for example, information on a map of a predetermined area. Note that in the example of Fig. 6A, for the sake of explanation, the outline of the map is shown in a schematic manner and is not necessarily precise. For ease of explanation, Fig. 6A shows an αβ Cartesian coordinate system, which is a two-dimensional Cartesian coordinate system. In the αβ Cartesian coordinate system, an origin γ, an α axis, and a β axis are shown. In this embodiment, the α direction parallel to the α axis corresponds to the so-called horizontal direction, and the β direction parallel to the β axis corresponds to the so-called vertical direction.

[0042] FIG. 6A shows an example of the first provision range 221 set for the A-th content 211A. The first provision range 221 represents the range of the information portion of the entire A-th content 211A that is provided to the destination by the service provision processing unit 146. In this embodiment, the destination is the first display device A1.

[0043] In this embodiment, the first display device A1 transmits request information to the server device D1 on a website provided by the server device D1. The service providing processing unit 146 of the server device D1 determines the first provision range 221 based on the request information received from the first display device A1. Then, the service provision processing unit 146 of the server device D1 transmits the information part of the A-th content 211A that is included in the determined first provision range 221 to the first display device A1. Here, the first display device A1 changes the request information as necessary and transmits it to the server device D1. The change in the request information from the first display device A1 changes the first provision range 221 in the server device D1, and changes the information transmitted from the server device D1 to the first display device A1.

[0044] FIG. 6B is a diagram showing an example of information on the Bth content 211B stored in the server device D1 according to the embodiment. The information of the B content 211B is, for example, information on an aerial photograph of a predetermined area. Note that in the example of Fig. 6B, for the sake of explanation, the outline of the aerial photograph is shown in a schematic manner and is not necessarily precise. For convenience of explanation, FIG. 6B shows an αβ orthogonal coordinate system, which is a two-dimensional orthogonal coordinate system. In this embodiment, for convenience of explanation, the same αβ orthogonal coordinate system is shown in Figures 6A and 6B, but as these coordinate systems, for example, different coordinate systems may be used, or a common coordinate system may be used. For example, different orthogonal coordinate systems that have a mutually understood correspondence may be used in Figures 6A and 6B.

[0045] FIG. 6B shows an example of the second provision range 222 set for the B content 211B. The second provision range 222 indicates the range of the information portion of the entire B-th contents 211B that is provided to the destination by the service provision processing unit 146. In this embodiment, the destination is the first display device A1.

[0046] In this embodiment, the first display device A1 transmits request information to the server device D1 on a website provided by the server device D1. The service providing processing unit 146 of the server device D1 determines the second provision range 222 based on the request information received from the first display device A1. Then, the service providing processing unit 146 of the server device D1 transmits the information part of the B-th content 211B that is included in the determined second provision range 222 to the first display device A1. Here, the first display device A1 changes the request information as necessary and transmits it to the server device D1. The change in the request information from the first display device A1 changes the second provision range 222 in the server device D1, and changes the information transmitted from the server device D1 to the first display device A1.

[0047] Screen sharing in a combination of a first display device A1 and a second display device A2 will be described with reference to Figures 7A, 7B, 8A, 8B, 9A, 9B, and 10. In this embodiment, the first display device A1 is the main display device, and the second display device A2 is the sub display device.

[0048] The two master layers in the first display device A1 will be described with reference to FIGS. 7A and 7B. In this embodiment, the first display device A1 constructs a first master layer 311 for storing images of content A to be displayed on the sharing source device, and a second master layer 312 for storing images of content B to be displayed on the sharing destination device.

[0049] FIG. 7A is a diagram showing an example of the configuration of the first master layer 311 in the first display device A1 according to the embodiment. 7A shows an XY Cartesian coordinate system, which is a two-dimensional Cartesian coordinate system, for the sake of convenience of explanation. In the XY Cartesian coordinate system, an origin O, an X axis, and a Y axis are shown. In this embodiment, the X direction parallel to the X axis corresponds to the so-called horizontal direction, with the positive side corresponding to the right side and the negative side corresponding to the left side. In this embodiment, the Y direction parallel to the Y axis corresponds to the so-called vertical direction, with the positive side corresponding to the top side and the negative side corresponding to the bottom side. The horizontal and vertical directions may be interpreted in reverse.

[0050] In this embodiment, the X direction and the Y direction in the XY Cartesian coordinate system are parallel to the α direction and the β direction in the αβ Cartesian coordinate system shown in FIGS. 6A and 6B, respectively. However, as another example, the X direction and the Y direction in the XY Cartesian coordinate system may correspond to the α direction and the β direction in the αβ Cartesian coordinate system shown in FIGS. 6A and 6B in another manner.

[0051] In the first display device A1, the first image processing unit 116 draws the master image of the Ath content on the first master layer 311. In this embodiment, the area of ​​the master image is called a master area.

[0052] In the example of FIG. 7A, a first master image G1 is shown as the master image drawn on the first master layer 311. In the example of FIG. 7A, a first master region F1 is shown as the master region of the first master image G1.

[0053] Here, the first master layer 311 may be, for example, a predetermined area provided in the recording area of ​​the first storage unit 114. In this case, the process of drawing the first master image G1 on the first master layer 311 may be a process of storing data of the first master image G1 in the first master layer 311 and memorizing the first master image G1. In this case, for example, the first master layer 311 and the first master area F1 may be considered to be substantially the same. 7A, the first master area F1 is a rectangular area surrounded by two line segments in the X direction parallel to the X axis and two line segments in the Y direction parallel to the Y axis. Note that a square may also be included as a type of rectangle.

[0054] In this example, the first image processing unit 116 of the first display device A1 transmits request information for the A-th content to the server device D1, and thereby acquires from the server device D1 an information portion of the first provision range 221 based on the request information. The information portion corresponds to map information of the first provision range 221. Then, the first image processing unit 116 of the first display device A1 draws the acquired map information as a first master image G1 on the first master layer 311.

[0055] In this embodiment, the request information includes information indicating the reference point and information indicating the aspect ratio. The reference point is a point that serves as a reference for setting the first provision range 221 in the A content 211A in the server device D1, and may be, for example, a point that is set as the center position of the first provision range 221 in the A content 211A. The aspect ratio is used as a value for setting the frame of the first provided range 221 with the reference point as the reference. Such information indicating the reference point may be considered to be coordinate information indicating the coordinates of the content. Furthermore, the combination of such a reference point and aspect ratio may also be considered to be coordinate information indicating the coordinates and range of the content. In other words, the request information may be considered to be information including the coordinate information of the content.

[0056] The service providing processing unit 146 of the server device D1 determines and sets the first providing range 221 suitable for the reference point and aspect ratio specified by the request information for the A-th content from the first display device A1. In this example, if one or both of the reference point and the aspect ratio specified by the request information of the A-th content change, the first provision range 221 may change.

[0057] In this embodiment, the first image processor 116 of the first display device A1 determines the aspect ratio to be included in the request information for the content A based on the aspect ratio of the first display screen B1 of the first display device A1. These aspect ratios may be the same, for example.

[0058] In the first display device A1, for example, the aspect ratio of the first display screen B1 is stored in the first storage unit 114 in advance.

[0059] 7A, the first image processing unit 116 of the first display device A1 sets a first region H1 in the first master region F1 that matches the aspect ratio of the first display screen B1 of the first display device A1. The first image processing unit 116 of the first display device A1 then crops the image portion included in the first region H1 and displays it on the first display screen B1. Here, the first region H1 is, for example, the same as the first master region F1, but may be different. Trimming may also be called, for example, cutting out. The first area H1 may be associated with the first master layer 311 or the first master area F1, for example, using coordinates in an XY Cartesian coordinate system.

[0060] FIG. 7B is a diagram showing an example of the configuration of the second master layer 312 in the first display device A1 according to the embodiment. For convenience of explanation, FIG. 7B shows an XY Cartesian coordinate system, which is a two-dimensional Cartesian coordinate system. 7A and 7B show the same XY Cartesian coordinate system for the sake of convenience, but different coordinate systems may be used as these coordinate systems, or a common coordinate system may be used. For example, different Cartesian coordinate systems that have a mutually understood correspondence may be used in FIGS. 7A and 7B.

[0061] In the first display device A1, the first image processing unit 116 draws the master image of the B content on the second master layer 312. In the example of FIG. 7B, a second master image G2 is shown as the master image drawn on the second master layer 312. In the example of FIG. 7B, a second master region F2 is shown as the master region of the second master image G2.

[0062] Here, the second master layer 312 may be, for example, a predetermined area provided in the recording area of ​​the first storage unit 114. In this case, the process of drawing the second master image G2 on the second master layer 312 may be a process of storing data of the second master image G2 in the second master layer 312 and memorizing the second master image G2. In this case, for example, the second master layer 312 and the second master area F2 may be considered to be substantially the same. 7B, the second master area F2 is a rectangular area surrounded by two line segments in the X direction parallel to the X axis and two line segments in the Y direction parallel to the Y axis. Note that a square may also be included as a type of rectangle.

[0063] In this example, the first image processing unit 116 of the first display device A1 transmits request information for the B content to the server device D1, and thereby acquires from the server device D1 an information portion of the second provision range 222 based on the request information. The information portion corresponds to aerial photograph information of the second provision range 222. Then, the first image processing unit 116 of the first display device A1 renders the acquired aerial photograph information as a second master image G2 on the second master layer 312.

[0064] In this embodiment, the request information includes information indicating the reference point and information indicating the aspect ratio. The reference point is a point that serves as a reference for setting the second provision range 222 in the B content 211B in the server device D1, and may be, for example, a point that is set as the center position of the second provision range 222 in the B content 211B. The aspect ratio is used as a value for setting the frame of the second provided range 222 with the reference point as the reference.

[0065] The service providing processing unit 146 of the server device D1 determines and sets the second providing range 222 suited to the reference point and aspect ratio specified by the request information for the B-th content from the first display device A1. In this example, if one or both of the reference point and the aspect ratio specified by the request information of the B-th content change, the second provision range 222 may change.

[0066] In this embodiment, the first image processor 116 of the first display device A1 determines the aspect ratio to be included in the request information for the Bth content based on the aspect ratio of the second display screen B2 of the second display device A2. These aspect ratios may be the same, for example.

[0067] In this embodiment, for example, the first display device A1 may have the aspect ratio of the second display screen B2 of the second display device A2 stored in advance in the first storage unit 114, or may obtain information specifying the aspect ratio of the second display screen B2 of the second display device A2 from the second display device A2 or another device. The other device may be the server device D1. For example, the first display device A1 may obtain the aspect ratio of the second display screen B2 of the second display device A2 from the second display device A2 or another device in real time during screen sharing or the like.

[0068] In the example of Figure 7B, the first image processing unit 116 of the first display device A1 sets a second region H2 in the second master region F2 that matches the aspect ratio of the second display screen B2 of the second display device A2. The first image processing unit 116 of the first display device A1 then crops the image portion included in the second region H2 and transmits it to the second display device A2. The second image processing unit 126 of the second display device A2 then displays and outputs the image portion on the second display screen B2. Here, the second region H2 is, for example, the same as the second master region F2, but may be different. The second area H2 may be associated with the second master layer 312 or the second master area F2, for example, using coordinates in an XY Cartesian coordinate system.

[0069] In this embodiment, the aspect ratio of the first display screen B1 of the first display device A1 is (16:9) in the Y direction:X direction, and the resolution is (1920:1080). In this embodiment, the aspect ratio of the second display screen B2 of the second display device A2 is (9:16) in the Y direction:X direction, and the resolution is (1080:1920). In this way, the aspect ratio of the first display screen B1 and the aspect ratio of the second display screen B2 are different.

[0070] Here, in the first display device A1, the first master image G1 of the A content and the second master image G2 of the B content are associated with each other using coordinates. For example, the first region H1 and the second region H2 may be associated with each other using coordinates in an XY Cartesian coordinate system, or may be associated with each other using a relative positional relationship. In this embodiment, the map information, which is content A, and the aerial photograph information, which is content B, represent information on the same location at the same coordinate values, but as another example, content A and content B may each be any content.

[0071] FIG. 8A is a diagram showing an example of a first image C1 displayed on a first display screen B1 of a first display device A1 according to the embodiment. In the example of FIG. 8A, the first icon 411 is displayed overlapping the first image C1. The first icon 411 may be displayed, for example, at the center of the first display screen B1, or may be displayed at another position.

[0072] FIG. 8B is a diagram showing an example of a second image C2 displayed on the second display screen B2 of the second display device A2 according to the embodiment. In the example of FIG. 8B, the second icon 412 is displayed overlapping the second image C2. For example, the second icon 412 may indicate the same position on an aerial photograph as the position on a map indicated by the first icon 411. The first icon 411 may be displayed at the center of the first display screen B1, and the second icon 412 may be displayed at the center of the second display screen B2.

[0073] In this example, the first image C1 and the second image C2 are synchronized with each other based on coordinates, which may be, for example, latitude and longitude. In this example, when the display content of the first image C1 displayed on the first display screen B1 of the first display device A1 changes, the first image processing unit 116 of the first display device A1 performs image processing so that the display content of the second image C2 displayed on the second display screen B2 of the second display device A2 also changes in response to the change. As a result, the coordinates of the second image C2 also move in response to the movement of the coordinates of the first image C1.

[0074] FIG. 9A is a diagram showing an example of an image 1a C1a displayed on the first display screen B1 of the first display device A1 according to the embodiment. In the example of FIG. 9A, the 1a icon 411a is displayed overlapping the 1a image C1a. The 1ath icon 411a is the same as the first icon 411.

[0075] FIG. 9B is a diagram showing an example of a 2a image C2a displayed on the second display screen B2 of the second display device A2 according to the embodiment. In the example of FIG. 9B, the 2a icon 412a is displayed overlapping the 2a image C2a. The second icon 412a is the same as the second icon 412.

[0076] 9A shows a state in which the first display screen B1 of the first display device A1 is swiped in a first direction Dr1 by a finger 431 of the first user E1. In this example, the first display screen B1 is a touch panel, but the operation in the first direction Dr1 may be performed by operating a button, a key, or the like instead of swiping. In the example of Fig. 9A, a 1a image C1a is displayed, which is an image in which the first image C1 shown in Fig. 8A is being moved in the second direction Dr2 by the coordinates of the swipe. Note that in the example of Fig. 9A, for the sake of simplicity, an image similar to the first image C1 is shown as the 1a image C1a, but in reality, the displayed content gradually shifts as the user swipes. Here, the second direction Dr2 is the opposite direction to the first direction Dr1. In the example of Fig. 9A, the first direction Dr1 is the right direction, and the second direction Dr2 is the left direction. Note that instead of the left-right direction, the first direction Dr1 may be the up-down direction or a diagonal direction.

[0077] Fig. 9B shows a 2a image C2a, which is an image in which the second image C2 shown in Fig. 8B is being moved in the third direction Dr3 by the same coordinates as the change in the first image C1. Note that in the example of Fig. 9B, for the sake of simplicity, an image similar to the second image C2 is shown as the 2a image C2a, but in reality, the displayed content gradually shifts as the user swipes. Here, the third direction Dr3 is the same direction as the second direction Dr2. In this way, when the image displayed on the first display screen B1 of the sharing source moves, the image displayed on the second display screen B2 of the sharing destination also moves in synchronization with the movement.

[0078] It should be noted that the finger 431, the arrow indicating the first direction Dr1, and the arrow indicating the second direction Dr2 shown in FIG. 9A are shown for the purpose of explanation, and are not displayed on the first display screen B1. Moreover, the arrow indicating the third direction Dr3 shown in FIG. 9B is shown for the purpose of explanation and is not displayed on the second display screen B2.

[0079] For example, it is possible to share a video by network streaming from the first display device A1 to the second display device A2. The first display device A1, which is the source of sharing, prepares a first master layer 311, which is a display layer for displaying video on its own display, and also prepares a second master layer 312, which is an external display layer for screen sharing on an external display. The first display device A1, which is the sharing source, then draws different content on each of these two master layers based on the same coordinate information, and controls the display for each display.

[0080] In this example, an application utilizing such a mechanism can be used to perform display control such as the examples shown in FIGS. 8A, 8B, 9A, and 9B. The application handles map information and aerial photograph information. The application displays and outputs the display content of content A on the sharing source display and the display content of content B on the sharing destination display, and synchronizes these display contents based on, for example, latitude and longitude coordinates.

[0081] This means that, for example, when a map is displayed on the device from which the data is shared and an aerial photograph of the area corresponding to the map is displayed on the device to which the data is shared, if a coordinate shift is instructed by a first user E1 viewing the map on the device from which the data is shared, the coordinate shift of the aerial photograph on the device to which the data is shared can be synchronized with the coordinate shift of the map and displayed. In this example, coordinate movement by a swipe operation is illustrated, but as other examples, the screens of the sharing source and sharing destination may be linked to each other for image reduction by a pinch-in operation, image enlargement by a pinch-out operation, and image rotation by a rotation operation. The content displayed on the sharing source device and the content displayed on the sharing destination device may be reversed.

[0082] Here, in the examples of Figures 8A, 8B, 9A and 9B, when the display content of the first display screen B1 of the first display device A1 is moved, the display content of the first display screen B1 of the first display device A1 and the display content of the second display screen B2 of the second display device A2 are moved in conjunction with each other, and the first icon 411 displayed on the first display screen B1 and the second icon 412 displayed on the second display screen B2 remain in the center position of their respective display screens. As another example, in such a case, a mode may be used in which the first icon 411 displayed on the first display screen B1 and the second icon 412 displayed on the second display screen B2 move in conjunction with each other within the frame of each display screen.

[0083] In addition, the examples of Figures 8A, 8B, 9A and 9B show a mode in which icons are displayed on each of the first display screen B1 of the first display device A1 and the second display screen B2 of the second display device A2. As another example, an embodiment may be used in which icons are displayed on only one of the first display screen B1 of the first display device A1 and the second display screen B2 of the second display device A2. Here, whether or not to display an icon may be determined depending on the device, for example, the first display screen B1 of the first display device A1 or the second display screen B2 of the second display device A2, or may be determined depending on the type of display content, such as content A or content B.

[0084] FIG. 10 is a diagram showing an example of a procedure of processing performed when an image is displayed on the first display device A1 according to the embodiment. In this example, the sharing source device is the first display device A1, and the sharing destination device is the second display device A2. In this example, the first display device A1 switches screen sharing on and off. This switching may be performed, for example, by the first user E1 operating the first display device A1, or may be performed automatically according to a predetermined switching condition.

[0085] In step S1, in the first display device A1, which is the sharing source device, the first image processing unit 116 prepares the first master layer 311 and the second master layer 312 as preparations for the master layers. Next, in step S2, in the first display device A1, the first image processing unit 116 draws the display content on the master layer. In this example, the first image processing unit 116 draws a first master image G1 of the A content on the first master layer 311, and draws a second master image G2 of the B content on the second master layer 312.

[0086] Next, in step S3, in the first display device A1, the first image processing unit 116 cuts out an appropriate portion from the first master layer 311, and displays the image of that portion on the first display screen B1. In this example, this appropriate portion is the first region H1. Furthermore, this appropriate portion is cut out by trimming.

[0087] Next, in step S4, the first image processing unit 116 of the first display device A1 determines whether or not to start screen sharing. In this example, the first image processing unit 116 determines to start screen sharing if screen sharing is already set to on or if screen sharing is switched from off to on in real time. On the other hand, the first image processing unit 116 determines not to start screen sharing if screen sharing is set to off. In the determination of step S4, if the first image processing unit 116 of the first display device A1 determines that screen sharing should be started, the result of step S4 is YES, and the process proceeds to step S5. On the other hand, in the determination of step S4, if the first image processing unit 116 of the first display device A1 determines that screen sharing should not be started, the result is NO in step S4, and the process of this flow ends.

[0088] In step S5, the first image processing unit 116 of the first display device A1 cuts out an appropriate portion from the second master layer 312 and performs processing to display the image of that portion on the second display screen B2 of the second display device A2, which is the sharing destination device. Then, the processing of this flow ends. In this example, this appropriate portion is the portion of the second region H2. Furthermore, this appropriate portion is cut out by trimming.

[0089] As a specific example, while a first user E1 is viewing a first image C1 displayed on a first display screen B1 of a first display device A1, a second user E2 can view a second image C2 displayed on a second display screen B2 of a second display device A2. For example, the size of the second display screen B2 of the second display device A2 is larger than the size of the first display screen B1 of the first display device A1, and multiple users can simultaneously view the second image C2. For example, when the first user E1 operates the first display device A1 to give an instruction to shift the reference point of the first region H1, request information related to the updated A-th content with the shifted reference point is transmitted from the first display device A1 to the server device D1. As a result, the first provision range 221 on the server device D1 is updated, and the image portion transmitted from the server device D1 to the first display device A1 is updated. Then, the first master image G1 on the first display device A1 is updated, and the image content of the first image C1 is updated. Furthermore, in conjunction with the update of the image content of the first image C1, request information related to the updated B-th content with the shifted reference point is transmitted from the first display device A1 to the server device D1. As a result, the second provision range 222 on the server device D1 is updated, and the image portion transmitted from the server device D1 to the first display device A1 is updated. Then, the second master image G2 on the first display device A1 is updated, and the image content of the second image C2 is updated. As an example, when the reference point of the map information displayed on the first display screen B1 is shifted, the map information displayed on the first display screen B1 scrolls accordingly, and in synchronization with this, the aerial photograph information displayed on the second display screen B2 scrolls.

[0090] 11A and 11B, other content display examples are shown. FIG. 11A is a diagram showing an example of a 1b image C1b displayed on the first display screen B1 of the first display device A1 according to the embodiment. FIG. 11B is a diagram showing an example of a 2b image C2b displayed on the second display screen B2 of the second display device A2 according to the embodiment.

[0091] In this example, the content A displayed on the first display screen B1 of the sharing source is information content that displays images taken by an omnidirectional camera based on a specified position, allowing the viewer to view the actual scenery that exists around the specified position. An image captured by an omnidirectional camera may be called, for example, a 360-degree panoramic image. In the example of FIG. 11A, no icon is displayed on the first display screen B1 that displays the 1b image C1b based on the A content.

[0092] In this example, the B-th content displayed on the second display screen B2 of the sharing destination is map information content. In the example of FIG. 11B, a 2b icon 412b is displayed on the second display screen B2 that displays a 2b image C2b based on the B content. In this example, the position indicated by the 2b icon 412b in the 2b image C2b, which is map information, coincides with the reference position in the 1b image C1b, which is scenery information, but other configurations may also be used.

[0093] Here, in the examples of Figures 11A and 11B, similarly to the examples of Figures 9A, 9B, 10A and 10B, the first image processing unit 116 of the first display device A1 performs image processing so that the coordinate movement of the 2b image C2b displayed on the second display screen B2 of the sharing destination is synchronized with the coordinate movement of the 1b image C1b displayed on the first display screen B1 of the sharing source. In this example, coordinate movement by a swipe operation is illustrated, but as another example, the screens of the sharing source and sharing destination may be linked to each other when an image is reduced by a pinch-in operation or enlarged by a pinch-out operation. The content displayed on the sharing source device and the content displayed on the sharing destination device may be reversed.

[0094] Here, when the direction of the line of sight for viewing the scenery in the 1b image C1b displayed on the first display screen B1 of the sharing source changes within a 360-degree range, for example, the display orientation of the 2b image C2b displayed on the second display screen B2 of the sharing destination may not be changed, or may be changed. The display orientation is, for example, the north-south, east-west orientation on a map.

[0095] In this embodiment, the first display device A1 changes the request information sent to the server device D1 when a predetermined event occurs on the first display device A1, thereby changing the first master image G1. The event may be, for example, a predetermined operation such as scrolling performed by the first user E1 on the first display device A1, or a predetermined automatic operation such as scrolling performed on the first display device A1.

[0096] As another example, when a predetermined event occurs on the second display device A2, the second display device A2 may notify the first display device A1 of the occurrence, and the first display device A1 may change the request information that it sends to the server device D1 in response to the notification, thereby changing the first master image G1. The event may be, for example, a predetermined operation such as scrolling by the second user E2 on the second display device A2, or the occurrence of a predetermined automatic operation such as scrolling on the second display device A2. In this case, the notification from the second display device A2 to the first display device A1 is performed by the second display device A2 sending predetermined information to the first display device A1.

[0097] In this embodiment, it is assumed that an operation such as scrolling occurs only on one of the sharing source device and the sharing destination device, i.e., the other device cannot perform an operation such as scrolling. However, a configuration may be used in which operations such as scrolling can occur on both the sharing source device and the sharing destination device.

[0098] In addition, in this embodiment, when the first display device A1 shares its screen with the second display device A2, the first display device A1 generates an image suitable for the aspect ratio of the second display screen B2 of the second display device A2 based on the second master image G2, and transmits the generated image to the second display device A2. As another example, when the first display device A1 shares its screen with the second display device A2, the first display device A1 may transmit an image corresponding to the second master image G2 to the second display device A2, and the second display device A2 may generate an image suitable for the aspect ratio of the second display screen B2 based on the image received by the first display device A1 and display the generated image. This generation process may include, for example, setting the second region H2 and trimming. The first display device A1 stores the aspect ratio of the first display screen B1 in the first storage unit 114 or the like, and the second display device A2 stores the aspect ratio of the second display screen B2 in the second storage unit 124 or the like.

[0099] In addition, in this embodiment, the first display device A1 acquires the first master image G1 and the second master image G2 based on information received from the server device D1. As another example, for one or both of the first master image G1 and the second master image G2, the original information used to generate the master image may be stored in a predetermined database, and the first display device A1 may acquire the master image based on that information. As another example, for one or both of the first master image G1 and the second master image G2, the original information for generating the master image may be stored in the first memory unit 114 of the first display device A1, and the first display device A1 may acquire the master image based on that information.

[0100] For example, a configuration may be used in which the first master image G1 and the second master image G2 are provided to the first display device A1 from different server devices. Also, for example, a configuration may be used in which one of the first master image G1 and the second master image G2 is provided from the server device D1 to the first display device A1, and the other is stored in the first display device A1 or a predetermined database other than the server device.

[0101] While the above describes screen sharing between the first display device A1 and the second display device A2, similar screen sharing may also be applied to the combination of the first display device A1 and the third display device A3. In this case, for example, the first display device A1 acts as the master and the third display device A3 acts as the slave. Generally, similar operations are performed by the third display device A3 and the third user E3 instead of the second display device A2 and the second user E2. However, in this embodiment, the second display device A2 is a projector, whereas the third display device A3 is a tablet terminal, and operations may differ due to these differences.

[0102] As described above, in the display method and display system 1 according to this embodiment, a first display device A1, which is an information processing device having a first display area, acquires information on content A, coordinate information corresponding to content A, and information on content B corresponding to the coordinate information. The first display device A1 displays an image of first image data capable of displaying content A in the first display area, in accordance with the aspect ratio of the first display area. Next, a second display device A2, which is connected to the first display device A1 and has a second display area, acquires information on content B, and displays an image of second image data capable of displaying content B in the second display area, in accordance with the aspect ratio of the second display area.

[0103] Therefore, in the display method and display system 1 according to this embodiment, multiple contents associated by coordinate information can be displayed according to the aspect ratio of each display screen, thereby making effective use of the display area. In the display method and display system 1 according to this embodiment, for example, when screen sharing is performed from a mobile terminal, multiple contents can be synchronized based on coordinate information, thereby providing flexibility in the display content or display layout.

[0104] For example, in this embodiment, multiple pieces of content, such as maps or documents, with coordinate information are used, and images of different pieces of content synchronized based on the coordinate information are drawn on the screen sharing terminal and on another video device. The sharing terminal prepares a virtual master layer that draws images of different pieces of content to be supplied to the sharing destination, in addition to a master layer that draws the content displayed on that terminal. Such a virtual master layer is adjusted based on the coordinate information to fit the resolution or aspect ratio of the destination. As a result, in this embodiment, for example, content that is different from the content of the sharing source can be displayed at the sharing destination based on the coordinate information, thereby realizing flexible screen sharing.

[0105] Here, the effect of screen sharing in this embodiment will be explained by comparing it with a conventional example. In conventional screen sharing systems, when using a mobile terminal to share a screen with another video device such as an external display or projector via a network, mirroring was typically performed to copy the contents displayed on the mobile terminal's display screen onto the other video device. With this type of mirroring, when screen sharing is performed between a mobile device with a different aspect ratio and another video device, there are problems such as blank spaces on the screen where the image is not displayed, and the displayed image not fitting properly with the screen. Furthermore, when the screen sharing method is mirroring, there is a restriction that, for example, different contents cannot be shared between the sharing source and the sharing destination.

[0106] For example, when projecting an image from a mobile device onto a projector, it is possible to project the entire document, such as a PDF file, onto the projector. However, in the past, it was difficult to instruct the zooming in or zooming out of content, such as a map or document, being projected by a mobile device, and it was also difficult to display different content information on the sharing source and sharing destination while synchronizing with the operation of the mobile device.

[0107] In contrast to this, in this embodiment, the screen is shared between the source and destination by utilizing coordinate synchronization, which eliminates the problem of white space that occurs when screen mirroring is performed between multiple displays with different aspect ratios, for example, and makes it possible to properly fit each displayed image on each screen. In addition, in this embodiment, for example, even if the same coordinate information is used at the source and destination of sharing, different content information can be displayed at the source and destination of sharing, thereby increasing the flexibility of display and broadening the range of information provided.

[0108] In the display method according to this embodiment, the first display device A1 acquires coordinate information, acquires first content corresponding to the coordinate information, and acquires second content corresponding to the coordinate information. In addition, in the display method of this embodiment, the generated first image C1 is displayed on the first display screen B1 based on the first aspect ratio of the first display screen B1 of the first display device A1 and the first content. In addition, in the display method according to this embodiment, the generated second image C2 is displayed on the second display screen B2 based on the second aspect ratio of the second display screen B2 of the second display device A2 and the second content.

[0109] Therefore, in the display method according to this embodiment, for example, multiple contents associated by coordinate information can be displayed in accordance with the aspect ratio of each display screen, thereby making effective use of the display area of ​​each display screen. In this embodiment, the A-th content is an example of the first content, and the B-th content is an example of the second content.

[0110] Note that, here, the example is explained using a case where the sharing source device is the first display device A1 and the sharing destination device is the second display device A2, but the same effect can be obtained, for example, when the sharing destination device is the third display device A3, except for the difference that the second display device A2 is a projector and the third display device A3 is a tablet terminal.

[0111] In the display method according to the present embodiment, the first display device A1 receives a first operation for updating the first image C1. Furthermore, in the display method according to the present embodiment, the second image C2 is updated based on the first operation and the coordinate information. Therefore, in the display method according to this embodiment, when the first user E1 operates the first display device A1, for example, it is possible to achieve screen linkage with the second display device A2. However, such a configuration does not necessarily have to be used.

[0112] In the display method according to the present embodiment, the first operation includes at least one of a swipe operation, a pinch-in operation, a pinch-out operation, and a rotation operation. Therefore, in the display method according to the present embodiment, when a map or the like is displayed on the first display screen B1, the first user E1 can perform an intuitive operation. Here, these operations may be performed, for example, when the first display screen B1 is configured as a touch panel. However, such a configuration does not necessarily have to be used.

[0113] In the display method according to this embodiment, information representing at least a part of the coordinate information is displayed on the first display screen B1 or the second display screen B2.
