(Knowledge that became the basis of the present invention)
The inventor of the present application has found that the following problems occur with respect to a conventional information display terminal.

In other words, as described above, the conventional technology does not disclose a configuration and a procedure for sending information suitable for a communication terminal from a tablet computer that is an information display terminal to the communication terminal.

Therefore, for example, when transmitting image data from a tablet computer to a communication terminal having a display screen smaller than that of the tablet computer, there arises a problem such as what image data should be transmitted.

In order to solve such a problem, an information display device according to one aspect of the present invention is an information display device having a display screen, and a storage unit that stores first data processed by the information display device; When information corresponding to the first data is displayed on the display screen and a communication terminal capable of communicating with the information display device is disposed within a predetermined distance from the display screen , Corresponding to the terminal position specified by the specifying unit, a specifying unit that specifies a terminal position that is a position in the display screen specified by a positional relationship between the communication terminal and the display screen, A data transmission unit that acquires terminal-corresponding data, which is at least part of data, from the storage unit, and transmits the acquired terminal-corresponding data to the communication terminal.

According to this configuration, when the communication terminal is arranged within a predetermined distance from the display screen of the information display device, data corresponding to the position of the communication terminal (terminal-corresponding data) is transmitted via wireless communication to the communication terminal. Sent to.

That is, in other words, the range and type of information to be transmitted from the information display device to the communication terminal can be easily specified and specified by holding the communication terminal over the display screen of the information display device or bringing it into contact. The information is transmitted from the information display device to the communication terminal.

As described above, the information display device according to this aspect performs identification of information suitable for a communication terminal arranged within a predetermined distance from the display screen from information held by itself and transmission to the communication terminal. It can be done efficiently.

For example, the storage unit stores image data that is the first data, and the display screen displays an image indicated by the image data that is information corresponding to the first data, and transmits the data. The unit acquires partial image data corresponding to the terminal position, which is the terminal correspondence data, from the image data stored in the storage unit.

According to this configuration, for example, it is possible to cause the communication terminal to acquire partial image data that is at least a part of the image data displayed on the display screen and corresponds to the terminal position. .

Further, for example, the storage unit stores a first storage unit that stores first image data that is the image data before processing for drawing on the display screen, and the drawing on the first image data. A second storage unit that stores second image data, which is the image data for drawing on the display screen, obtained by processing for the display screen, and the data transmission unit includes the first transmission unit Selecting one of the first image data stored in the storage unit and the second image data stored in the second storage unit, and acquiring the partial image data from the selected one Also good.

According to this configuration, the information display apparatus, for example, converts one of the first image data and the second image data, which are image data before and after processing such as enlargement or reduction, to a resolution or a data size, for example. Or the like. Moreover, the partial image data acquired from the selected one can be transmitted to the communication terminal.

Further, for example, the storage unit stores entity data to be processed by a predetermined application program that is the first data, and the display screen is displayed in the entity data that is information corresponding to the first data. The data transmitting unit obtains at least a part of the entity data corresponding to the terminal position, which is the terminal-corresponding data, from the entity data stored in the storage unit; At least a part of the acquired entity data is transmitted as the terminal correspondence data.

According to this configuration, for example, a text file created by word processing software is stored as entity data in the storage unit, and the text shown in the text file is displayed on the display screen. Further, when the communication terminal is arranged so as to be held over or in contact with the text displayed on the display screen, for example, all or a part of the text file can be acquired by the communication terminal.

Further, for example, the storage unit stores entity data to be processed by a predetermined application program that is the first data, and the display screen corresponds to the entity data that is information corresponding to the first data. The attached image is displayed, and when the terminal position and the position of the image on the display screen are in a predetermined relationship, the data transmission unit receives the entity data that is the terminal-corresponding data from the storage unit. The acquired entity data may be transmitted as the terminal-corresponding data.

According to this configuration, for example, when an image such as an icon associated with entity data such as a text file or a moving image file is displayed on the display screen, the communication terminal disposed within a predetermined distance from the image is displayed. The entity data can be acquired.

In addition, for example, the storage unit stores a predetermined application program that is the first data, and the display screen is an image associated with the predetermined application program that is information corresponding to the first data. And when the terminal position and the position of the image on the display screen are in a predetermined relationship, the data transmission unit acquires the predetermined application program that is the terminal-corresponding data from the storage unit. The acquired predetermined application program may be transmitted as the terminal-compatible data.

According to this configuration, for example, when an image such as an icon associated with a predetermined application program is displayed on the display screen, the predetermined application is connected to a communication terminal arranged within a predetermined distance from the image. You can get a program.

For example, the storage unit further stores second data associated with the first data, and the data transmission unit further includes the terminal position and the display of the image indicated by the first data. When the position on the screen has a predetermined relationship, the second data may be acquired from the storage unit, and the acquired second data may be transmitted to the communication terminal.

According to this configuration, the second data corresponding to the image displayed on the display screen and corresponding to the image indicated by the first data, together with the terminal corresponding data, for example, a communication terminal placed on the image, Alternatively, the image is transmitted to the communication terminal held over the image.

In addition, for example, the storage unit stores the first data indicating an image corresponding to a predetermined application program, stores the second data that is the predetermined application program, and the data transmission unit further includes: When the terminal position and the position on the display screen of the image indicated by the first data have a predetermined relationship, the application program that is the second data is acquired from the storage unit, and the acquired application program May be transmitted to the communication terminal.

According to this configuration, for example, the communication terminal placed on the icon or the communication terminal held over the icon, for example, the data corresponding to the icon as the terminal-corresponding data, and the predetermined corresponding to the icon The application program is transmitted as the second data.

Further, for example, the storage unit stores the first data indicating an image associated with entity data to be processed by a predetermined application program, stores the second data that is the entity data, and stores the data The transmission unit further acquires the entity data as the second data from the storage unit when the terminal position and the position of the image indicated by the first data on the display screen have a predetermined relationship. The acquired entity data may be transmitted to the communication terminal.

According to this configuration, for example, a communication terminal placed on an icon or a communication terminal held over the icon corresponds to the icon together with the icon data as terminal-corresponding data. Substantive data such as a text file or a moving image file is transmitted as second data.

As described above, the information display device can transmit not only the image displayed on the display screen but also information related to the image to the communication terminal.

In addition, for example, when the request for transmitting the second data is transmitted from the communication terminal to the information display device after transmitting the terminal-corresponding data, as a response to the request, The second data may be transmitted to the communication terminal.

According to this configuration, in response to a request from a communication terminal that is a destination of terminal-compatible data indicating an image such as an icon, for example, an application program or entity data corresponding to the image is transmitted as second data to the communication terminal. Is done.

Therefore, for example, even when a plurality of icon data is transmitted to the communication terminal as terminal-corresponding data, among the plurality of second data corresponding to the icon data, the communication terminal actually needs Only two data are transmitted to the communication terminal. That is, the execution of communication that is wasted as a result is prevented.

Further, for example, when the communication terminal is placed on the display screen, the specifying unit may specify the terminal position by detecting the position of the communication terminal on the display screen.

According to this configuration, for the communication terminal placed on the display screen, the terminal corresponding data corresponding to the placed position is specified and transmitted to the communication terminal. That is, the information display apparatus performs identification and transmission of appropriate information to the communication terminal placed on the display screen.

Further, for example, the specifying unit further specifies a partial area corresponding to the terminal position, which is a partial display area in the display screen, and the data transmission unit is stored in the storage unit The terminal correspondence data indicating the data displayed in the partial area may be acquired from the first data.

According to this configuration, for example, data such as an image or text in a partial region corresponding to the position of the communication terminal on the display screen is cut out from the entire image displayed on the display screen, and the data corresponding to the terminal Sent to the communication terminal. In other words, in the entire image displayed on the display screen, the communication terminal is placed on the part to be captured by the communication terminal or the communication terminal is held over the part, so that data corresponding to the part is displayed. Can be acquired by the communication terminal.

Further, for example, the specifying unit may further detect an orientation of the communication terminal in a plane parallel to the display screen, and specify the partial region corresponding to the terminal position and the orientation.

According to this configuration, since the partial area is specified according to the orientation of the communication terminal on the display screen (rotation position around the axis perpendicular to the display screen), it is possible to transmit terminal-compatible data more suitable for the communication terminal. It becomes.

In addition, for example, the specific unit is at least one projecting portion provided in the communication terminal, and the at least one projecting portion provided on the opposite side of the terminal screen that is a screen of the communication terminal. The direction may be detected by using the detection result.

According to this configuration, for example, an adapter having the at least one protrusion, and by preparing an adapter that can be attached to a plurality of communication terminals, it does not depend on the shape of the back surface of the plurality of communication terminals, The certainty of the direction detection for each of the plurality of communication terminals is guaranteed.

In addition, for example, the information display device according to one aspect of the present invention further includes an identification information acquisition unit that acquires identification information of the communication terminal from the communication terminal, and the specifying unit corresponds to the identification information. Screen size information indicating a size of a terminal screen that is a screen of the communication terminal may be acquired, and the partial area corresponding to the terminal position and the size of the terminal screen indicated in the screen size information may be specified. .

According to this configuration, for example, terminal-corresponding data indicating an image having a size corresponding to the screen size of the terminal screen is transmitted to the communication terminal. Therefore, it is possible to transmit terminal-corresponding data more suitable for the communication terminal.

Further, for example, the information display device according to an aspect of the present invention further includes a device information table that stores at least the identification information of the communication terminal and the screen size information in association with each other, and the specifying unit includes: The screen size information may be acquired by reading the screen size information corresponding to the identification information from the device information table.

This configuration facilitates specification of the screen size using the identification information of the communication terminal. That is, it is possible to improve the efficiency of processing related to identification of terminal-compatible data and transmission to a communication terminal.

In addition, for example, the specifying unit transmits the screen size corresponding to the identification information transmitted from the server device by making an inquiry to the server device that is communicably connected to the information display device via an external network. Information may be acquired.

According to this configuration, for example, even when a communication terminal unknown to the information display device is placed on the display screen, it is possible to transmit the terminal-corresponding data according to the screen size of the communication terminal to the communication terminal It becomes.

Further, for example, the specifying unit may acquire screen size information corresponding to the identification information transmitted from the communication terminal.

According to this configuration, the information display device can acquire the screen size from the communication terminal that is the transmission destination of the terminal-compatible data. Therefore, for example, the appropriateness of the screen size used for specifying the partial area is guaranteed.

In the information display device 101, in addition to displaying image data, it is possible to execute various processes such as text editing, music playback, and games by executing an application.

The wireless communication terminal 103 is a communication terminal having a terminal screen 104 and a function for wireless communication with the information display device 101. The wireless communication terminal 103 is used as a relatively small screen information display device such as a mobile phone or a smartphone.

FIG. 2 is a block diagram illustrating an example of a basic functional configuration of the information display apparatus 101 according to the first embodiment.

As shown in FIG. 2, the information display apparatus 101 includes a specifying unit 201, a data transmission unit 204, and a storage unit 206 as a basic functional configuration for characteristic processing.

The storage unit 206 stores image data to be processed by the information display device 101. Image data is an example of first data. The storage unit 206 is realized by, for example, an HDD (Hard Disk Drive) or an SSD (Solid State Drive) that can store image data that is a source of an image displayed on the display screen 102. The storage unit 206 is read from a storage device such as an HDD or an SSD, for example, and is subjected to processing such as enlargement, reduction, or trimming for drawing according to the display size on the display screen 102. It can also be realized by a video memory (VRAM: Video Random Access Memory) in which image data is stored.

Furthermore, the storage unit 206 may be composed of a plurality of storage devices having different uses or types, such as an HDD, an SSD, and a video memory. That is, one physical storage device may be handled as the storage unit 206, and a plurality of storage devices that are separate from each other may be handled as the storage unit 206.

In the identification unit 201, information corresponding to the first data is displayed on the display screen 102, and a communication terminal capable of communicating with the information display device 101 is disposed within a predetermined distance from the display screen 102. If it is determined, the terminal position that is the position in the display screen 102 specified by the positional relationship between the communication terminal and the display screen 102 is specified.

In the present embodiment, the specifying unit 201 includes a detecting unit 201 and a region specifying unit 203.

The detecting unit 201 detects the terminal position of the wireless communication terminal 103 when the wireless communication terminal 103 is arranged within a predetermined distance from the display screen 102.

In the present embodiment, when the wireless communication terminal 103 is placed on the display screen 102, the detection unit 201 detects at least the position on the display screen 102 of the wireless communication terminal 103 that is the terminal position. That is, in the present embodiment, the detection unit 201 performs an operation in the case where the predetermined distance is substantially “0”.

The area specifying unit 203 specifies a partial area that is a partial display area in the display screen 102 corresponding to the terminal position detected by the detecting unit 201.

The partial image data is an example of terminal-corresponding data, and is image data corresponding to the partial area specified by the area specifying unit 203.

Note that the data transmission unit 204, for example, a method such as JPEG (Joint Photographic Experts Group), when acquiring partial image data from image data developed for drawing held in the storage unit 206, which is a video memory. The partial image data can be transmitted to the wireless communication terminal 103 after performing the compression according to the above.

When the storage unit 206 is a video memory, or when the storage unit 206 has a video memory, the drawing image data held in the storage unit 206 is image data that is a source as described above. On the other hand, it may be image data that has been subjected to processing for drawing.

Here, the drawing process may be a process of changing luminance, contrast, sharpness, brightness, saturation, or the like in addition to the above-described enlargement or the like. Further, the drawing process may be a process of converting a color image into a monochrome image or a sepia image.

Also, the drawing process may be a process that makes a person's skin color look beautiful, a process that makes a person's eyes look larger, or a process that makes a person look slim.

That is, the data transmission unit 204 can acquire partial image data from the image data developed for drawing, which is held in the storage unit 206 that is a video memory. As a result, the image data developed for drawing, which has been subjected to such processing, without actually adding such processing for drawing to the image data as the source, is converted to partial image data (terminal-compatible data). ) Can be easily transmitted to the wireless communication terminal 103.

A specific functional configuration example of the information display apparatus 101 having the basic functional configuration as described above will be described with reference to FIG.

The wireless communication interface 207 is an interface for exchanging information with an external device such as the wireless communication terminal 103 via wireless communication.

FIG. 4 is a diagram illustrating an example of a detection operation performed by the detection unit 201 according to the first embodiment.

Referring to FIG. 4, an example of processing in the present embodiment for each functional block included in the information display apparatus 101 will be described.

4A, the detecting unit 201 included in the specifying unit 200 in the present embodiment is realized by a touch panel installed on the display screen 102, for example. In the present embodiment, the detection unit 201 detects contact between the detection unit 201 and the user's finger, an object placed, and the like.

As the detection unit 201, for example, a pressure-sensitive detection device (touch panel) that measures pressure using a resistance film is employed.

Here, “the object (for example, the wireless communication terminal 103) is placed on the display screen 102” does not mean that the object is placed directly on the display screen 102, but the object is detected. It also means that the object is placed on the display screen 102 via another object such as the unit 201.

Similarly, “an object (for example, the wireless communication terminal 103) is in contact with the display screen 102” does not mean that the object is in direct contact with the display screen 102; It also means that the display screen 102 is touched via another object.

In the present embodiment, as shown in FIG. 4B, the detection unit 201 can detect a placement area 210 that is an area where the wireless communication terminal 103 is placed. Accordingly, the detection unit 201 can detect at least the orientation of the wireless communication terminal 103 in a plane parallel to the display screen 102 in addition to the terminal position.

Or, it is defined by the coordinate value of the center of the placement area 210 or the like.

Further, the orientation of the wireless communication terminal 103 in the plane parallel to the display screen 102 is, for example, the direction in the longitudinal direction of the rectangular placement region 210 parallel to the short side of the display screen 102 (in this embodiment, the Y axis). It is expressed by an inclination angle with respect to (direction).

For example, it is assumed that the direction of the wireless communication terminal 103 shown in FIGS. 4A and 4B is represented as “0”. In this case, when the wireless communication terminal 103 is rotated 45 degrees clockwise in a top view (when the display screen 102 is viewed from a direction parallel to the Z axis), the orientation of the wireless communication terminal 103 is “−45”. "It can be expressed as. When the wireless communication terminal 103 is rotated 45 degrees counterclockwise when viewed from above, the orientation of the wireless communication terminal 103 can be expressed as “45”.

In this embodiment, when detecting that an object is placed on the display screen 102, the detecting unit 201 notifies the identification information acquiring unit 202 and the region specifying unit 203. Further, the detection unit 201 obtains the position and orientation of the object from the detected placement area 210, and outputs these as detection information to the area specifying unit 203.

Upon receiving the notification from the detection unit 201, the identification information acquisition unit 202 attempts to perform wireless communication with the object via the wireless communication interface 207.

When the identification information acquisition unit 202 can wirelessly communicate with an object placed on the display screen 102, the identification information acquisition unit 202 determines that the object is a communication terminal capable of wireless communication, and uniquely identifies the communication terminal from the communication terminal.

FIG. 5 is a diagram illustrating a data configuration example of the device information table 205 according to the first embodiment.

In the device information table 205, information for each device such as identification information for each device (wireless communication terminal) and the screen size of the device is registered.

In the present embodiment, the device information table 205 holds a terminal name, identification information, screen size information, and screen resolution information as data items, for example, as shown in FIG.

Note that the device information table 205 illustrated in FIG. 5 is an example of information that the area specifying unit 203 refers to in order to specify the specifications of communication terminals arranged within a predetermined distance from the display screen 102. The device information table 205 may be in any format as long as it is at least information indicating the screen size of each communication terminal (hereinafter also simply referred to as “terminal”). Further, data items other than the data items shown in FIG. 5 may be stored in the device information table 205.

For example, the device information table 205 may include offset information of the terminal screen 104.

For example, a case is assumed where the position of the portion of the wireless communication terminal 103 corresponding to the upper left corner in the top view of the placement area 210 (see FIG. 4B) is used as the reference position. In this case, the distance in the X-axis direction and the Y-axis direction from the upper left corner of the terminal screen 104 to the reference position in the wireless communication terminal 103 may be recorded in the device information table 205 as offset information.

Thereby, the positional relationship between the placement area 210 and the terminal screen 104 can be specified more precisely. As a result, it is possible to specify the partial area for cutting out the partial image data with higher accuracy.

The wireless communication interface 207 performs wireless communication with an external device such as the wireless communication terminal 103 according to a predetermined communication protocol.

Note that the information display apparatus 101 and the wireless communication terminal 103 can perform wireless communication via a wireless LAN (Local Area Network) router, for example. Further, the information display device 101 and the wireless communication terminal 103 may exchange information on a one-to-one basis, for example, according to a short-range wireless communication standard such as Bluetooth (registered trademark).

In the present embodiment, the storage unit 206 stores applications and the like in addition to the image data displayed on the display screen 102.

The operation flow of the information display apparatus 101 according to the first embodiment configured as described above will be described with reference to FIGS.

FIG. 6 is a flowchart showing a basic operation flow of the information display apparatus 101 according to the first embodiment.

A basic operation flow of the information display apparatus 101 when the wireless communication terminal 103 is placed on the display screen 102 will be described with reference to FIG.

The specifying unit 200 displays information corresponding to the first data (image data in the present embodiment) on the display screen 102, and the wireless communication terminal 103 is disposed within a predetermined distance from the display screen 102. In this case, the terminal position of the wireless communication terminal 103 is specified (S10).

Specifically, the terminal position that is the position in the display screen 102 specified by the positional relationship between the wireless communication terminal 103 and the display screen 102 is specified.

In the present embodiment, when the wireless communication terminal 103 is placed on the display screen 102, the position of the wireless communication terminal 103 on the display screen 102 is specified as the terminal position.

The data transmission unit 204 acquires terminal-corresponding data that is at least a part of the first data corresponding to the terminal position from the storage unit 206, and transmits the acquired terminal-corresponding data to the wireless communication terminal 103 (S20). ).

In the present embodiment, the area specifying unit 203 included in the specifying unit 200 specifies a partial area that is a partial display area in the display screen 102 corresponding to the terminal position. Further, the data transmission unit 204 acquires terminal-corresponding data (partial image data) indicating data displayed in the partial area from the storage unit 206 and transmits the acquired data to the wireless communication terminal 103.

Next, an example of a specific operation flow of the information display apparatus 101 according to the first embodiment will be described with reference to FIG.

FIG. 7 is a flowchart showing a specific example of the operation flow of the information display apparatus 101 according to the first embodiment.

In the information display apparatus 101, the detection unit 201 determines whether something is placed on the display screen 102 (S101). When the detection unit 201 determines that something has been placed (Yes in S101), the detection unit 201 notifies the identification information acquisition unit 202 and the region specification unit 203 that an object has been placed on the display screen 102.

Also, the detection unit 201 detects the position and orientation of the placed object from the detected placement area 210 (see FIG. 4B) and outputs the detected information to the area specifying unit 203 as detection information. If the detection unit 201 determines that nothing is placed thereon (no in S101), the process proceeds to S101.

Upon receiving the notification from the detection unit 201, the identification information acquisition unit 202 broadcasts and transmits an identification information request signal via the wireless communication interface 207 (S102).

The identification information acquisition unit 202 determines whether or not an identification information response signal that is a response to the identification information request signal is received within a predetermined time (S103).

When it is determined that the identification information response signal has been received within a predetermined time (yes in S103), the identification information acquisition unit 202 outputs the identification information indicated in the received identification information response signal to the region specifying unit 203.

When it is determined that the identification information response signal has not been received within a predetermined time (no in S103), the identification information acquisition unit 202 determines that an object that cannot perform wireless communication is placed on the display screen 102, and S101. Return to the process.

When the identification information is output from the identification information acquisition unit 202, the area specifying unit 203 determines whether the output identification information is registered in the device information table 205 (S104).

If the area specifying unit 203 determines in S104 that the identification information is registered in the device information table 205 (Yes in S104), the area specifying unit 203 determines from the device information table 205 the screen size information of the terminal corresponding to the identification information and Device information such as screen resolution information is acquired (S105).

When determining that the identification information is not registered in the device information table 205 (no in S104), the area specifying unit 203 uses the data of the detection information output by the detection unit 201. Specifically, in this case, since the device information such as the screen size of the wireless communication terminal placed on the display screen 102 is not known, for the device information that cannot be acquired, for example, a predetermined value set in advance is Used to specify the area.

Alternatively, for example, the position, shape, and orientation of the placement area 210 indicated in the detection information output from the detection unit 201 (for example, the long side direction of the rectangle formed by the placement area 210 on the display screen 102) The inclination with respect to the short side direction) is used to specify the following partial areas.

The area specifying unit 203 determines a partial area that is a cut-out area in the image data displayed on the information display device 101 from the device information acquired from the device information table 205 and the detection information output from the detection unit 201 ( S106). The area specifying unit 203 outputs the identification information and the partial area information to the data transmission unit 204.

The data transmission unit 204 reads partial image data indicating an image corresponding to the partial region specified by the region specifying unit 203 from the storage unit 206. The data transmission unit 204 further transmits the read partial image data to the terminal having the identification information received from the region specifying unit 203 via the wireless communication interface 207 (S107).

Next, specific examples of operations and display contents of the wireless communication terminal 103 and the information display device 101 when the wireless communication terminal 103 is placed on the display screen 102 of the information display device 101 will be described with reference to FIGS. To do.

FIG. 8 is a sequence diagram showing a flow of operations of the information display device 101 and the wireless communication terminal 103 in the first embodiment.

FIG. 9 is a diagram illustrating a state where the wireless communication terminal 103 according to the first embodiment is placed on the display screen 102 illustrated in FIG.

FIG. 10 is a diagram illustrating a state in which the wireless communication terminal 103 illustrated in FIG. 9 is moved out of the information display device 101.

For example, assume a case where the wireless communication terminal 103 is placed on the display screen 102 of the information display device 101 as shown in FIG. In this case, in the information display apparatus 101, when the detection unit 201 detects that the wireless communication terminal 103 is placed on the display screen 102 (S501), the wireless communication terminal 103 is placed on the identification information acquisition unit 202. To be notified.

Also, the detection unit 201 detects the position and orientation of the wireless communication terminal 103 and transmits detection information including these to the region specifying unit 203.

Upon receiving the notification from the detection unit 201, the identification information acquisition unit 202 transmits the identification information request signal to the wireless communication terminal 103 by broadcasting the identification information request signal via the wireless communication interface 207 (S502). ).

Upon receiving the identification information request signal, the wireless communication terminal 103 returns an identification information response signal indicating identification information unique to the wireless communication terminal 103 to the information display apparatus 101 (S503).

In this case, it is assumed that the returned identification information is “0xBBBBBBBB”. When receiving the identification information response signal, the identification information acquisition unit 202 outputs the identification information “0xBBBBBBBB” included in the received identification information response signal to the region specifying unit 203.

The area specifying unit 203 searches whether the identification information “0xBBBBBBBB” output from the identification information acquisition unit 202 is registered in the device information table 205 illustrated in FIG. 5 (S504).

When the area specifying unit 203 finds “0xBBBBBBBB” in the identification information column of the device information table 205, it acquires the device information of the wireless communication terminal 103 (S505). In this case, the area specifying unit 203 acquires the terminal name “terminal B”, the screen size “4.3 inches”, and the screen resolution “1280 × 720” as the device information of the wireless communication terminal 103 (see FIG. 5).

The area specifying unit 203 determines the display screen 102 based on the position and orientation on the display screen 102 of the wireless communication terminal 103 included in the detection information, the screen size of the terminal screen 104 of the wireless communication terminal 103 acquired from the device information table 205, and the like. The partial area in is specified. That is, the area specifying unit 203 specifies the cutout range in the image data displayed on the display screen 102.

The data transmission unit 204 reads partial image data, which is image data corresponding to the partial area specified by the area specifying unit 203, from the storage unit 206 (S506).

The data transmission unit 204 transmits the partial image data to the wireless communication terminal 103 via the wireless communication interface 207 (S507).

In the present embodiment, partial image data corresponding to the screen size (4.3 inches) and the screen resolution (1280 × 720) is transmitted to the wireless communication terminal 103 by the data transmission unit 204.

Specifically, the image data (partial image data) of the partial area corresponding to 4.3 inches which is the screen size of the wireless communication terminal 103 is read out. Further, partial image data obtained by changing the resolution of the partial image data to 1280 pixels vertically and 720 pixels horizontally is transmitted from the data transmission unit 204.

Note that this resolution change may not be performed by the information display apparatus 101 but may be performed by the wireless communication terminal 103.

The wireless communication terminal 103 receives the partial image data transmitted from the information display device 101 and displays it on the terminal screen 104 (S508).

As a result of the above operation, as shown in FIG. 9, among the image data displayed on the display screen 102 of the information display device 101, partial image data corresponding to the position and orientation of the wireless communication terminal 103 is displayed on the terminal screen. 104.

Note that the series of operations shown in FIG. 9 is repeated at predetermined intervals, for example. Alternatively, for example, the detection unit 201 is executed every time when the movement of the wireless communication terminal 103 on the display screen 102 is detected.

That is, when the user moves the wireless communication terminal 103 so as to trace the surface of the display screen 102, the image displayed on the terminal screen 104 is changed in accordance with the movement.

Alternatively, an area having a size corresponding to the movement path of the wireless communication terminal 103 may be specified as a partial area, and partial image data corresponding to the specified partial area may be transmitted to the wireless communication terminal 103.

For example, it is assumed that the wireless communication terminal 103 is moved so that the entire cat image shown in FIG. 9 is scanned on the back surface of the wireless communication terminal 103. In this case, the information display device 101 identifies the area including the entire cat image as a partial area, and as a result, the partial image data including the entire cat image is transmitted to the wireless communication terminal 103.

In this case, the start point and the end point of the movement path of the wireless communication terminal 103 used for specifying the partial area may be specified by an explicit instruction from the wireless communication terminal 103, for example.

Further, for example, when the wireless communication terminal 103 starts moving within a predetermined period after being placed on the display screen 102, the movement trace from the start to the stop of the movement corresponds to the movement trace. A partial region to be specified may be specified.

Also, for example, before the start of the series of operations shown in FIG. 9, an application for image acquisition is started in the wireless communication terminal 103, and identification information is returned as a response to the identification information request signal (S502) (S503). ) Is executed by the application.

Also, the application executes processing such as writing partial image data to a memory (not shown) of the wireless communication terminal 103 and displaying it on the terminal screen 104.

FIG. 10 shows a state where the wireless communication terminal 103 is moved out of the information display device 101 after the series of operations shown in FIG. 8 is executed.

As shown in FIG. 10, the image data displayed on the display screen 102 of the information display device 101 at the time when the wireless communication terminal 103 is placed on the information display device 101 overlaps the terminal screen 104 of the wireless communication terminal 103. It can be seen that the image data (partial image data) of the region is cut out.

As described above, according to the information display apparatus 101 in the present embodiment, only the wireless communication terminal 103 is placed on the display screen 102, and partial image data corresponding to the placed position is displayed on the display screen 102. It is possible to cut out from the displayed image data and transmit it.

Note that device information such as the screen size of the wireless communication terminal 103 may be acquired from other than the device information table 205. For example, assume that there is no identification information of the wireless communication terminal 103 placed on the display screen 102 in the device information table 205.

In this case, for example, as shown in FIG. 11, the server device 801 having the device information of each of the plurality of terminals is inquired of the device information corresponding to the identification information via the external network. Device information may be acquired.

For example, the identification information acquisition unit 202 may acquire device information such as the screen size of the terminal from the wireless communication terminal 103 placed on the display screen 102.

That is, the information display device 101 does not need to hold the device information table 205, and device information about the terminal placed on the display screen 102 may be acquired from a device outside the information display device 101.

Also, the area specifying unit 203 may not use device information such as the screen size for specifying the partial area. The area specifying unit 203 may specify a partial area only from the terminal position of the wireless communication terminal 103 placed on the display screen 102.

For example, it is assumed that the area specifying unit 203 receives the coordinate value of the center of the placement area 210 (see FIG. 4B) as the terminal position from the detection unit 201. In this case, a predetermined rectangular area centered on the coordinate value (for example, an area corresponding to a 4.3-inch screen having a long side parallel to the Y-axis direction) is specified as a partial area. Also good.

In this case, the data transmission unit 204 transmits the partial image data obtained by changing the resolution of the partial image data corresponding to the partial area to a predetermined resolution (for example, vertical 1280 × horizontal 720). Also good.

That is, a preset value may be adopted as device information such as a screen size and a screen resolution for specifying the partial area. Further, for example, a screen size estimated from the size of the placement area 210 may be used for specifying the partial area.

In other words, at least the terminal position is used for specifying the partial area, so that the terminal placed on the display screen 102 of the information display device 101 can display, for example, an image of the area including the placed position. .

Further, the first data may be other types of data than image data. For example, the first data may be entity data that is a processing target of a predetermined application program.

Such entity data includes a text file created or edited by a text editor, a text file created or edited by a word processing software, a video file played by a video playback application, and an image editing application. Examples include a still image file to be edited.

For example, a sentence file that is entity data is stored in the storage unit 206 as first data, and the sentence shown in the sentence file is displayed in a window drawn on the display screen 102 as information corresponding to the first data. Assume a case.

Furthermore, when the wireless communication terminal 103 is placed over the window, the wireless communication terminal 103 is placed so that a part of the wireless communication terminal 103 (for example, a corner portion of the wireless communication terminal 103) contacts the window. It is assumed that the wireless communication terminal 103 is placed on the window. Note that a method for specifying the terminal position when the wireless communication terminal 103 and the display screen 102 are in a non-contact state will be described later.

In this case, as the terminal-corresponding data, for example, a partial data of the sentence file indicating the character string in the partial area is acquired from the sentence file stored in the storage unit 206 and transmitted to the wireless communication terminal 103. May be.

Further, for example, a part of the data of the sentence file indicating the character string displayed in the window may be transmitted to the wireless communication terminal 103 as the terminal-corresponding data. That is, in the display screen 102, when the partial area overlaps at least a part of the display area of the window, the data in the window may be acquired by the data transmission unit 204 as terminal-corresponding data. Alternatively, for example, when the terminal position is within the display area of the window, the display area of the window is specified as a partial area by the area specifying unit 203, and as a result, the data in the window is sent to the data transmitting unit 204 as terminal-corresponding data. May be acquired.

In addition, when some data of the text file is transmitted to the wireless communication terminal 103 as terminal-corresponding data, the partial data is, for example, a wireless file as a general-purpose text file or a file having the same format as the text file. It is transmitted to the communication terminal 103.

Further, for example, not all of the entity data but all of the entity data, that is, the sentence file stored in the storage unit 206 and displayed on the display screen 102 is the wireless communication terminal as the terminal-corresponding data. 103 may be transmitted. At this time, format conversion may be performed on the text file, and data obtained by the conversion may be transmitted to the wireless communication terminal 103.

As described above, when the entity data that is the first data is data including text information such as a text file, even if data including at least text information such as a character code is transmitted to the wireless communication terminal 103 as terminal-corresponding data. Good.

Further, for example, when the entity data as the first data is a moving image file, a part or all of one frame displayed when the terminal position is detected, a moving image of a predetermined period including the frame, Alternatively, the entire moving image file or the like may be transmitted to the wireless communication terminal 103 as terminal-compatible data.

That is, when the entity display data such as a text file is displayed on the display screen 102 by being processed by a predetermined application program, the information display device 101 uses at least a part of the entity data as terminal-corresponding data. It is also possible to transmit to the wireless communication terminal 103.

Further, for example, a case where a predetermined application program is stored in the storage unit 206 as first data to be processed by the information display apparatus 101 and an icon corresponding to the predetermined application program is displayed on the display screen 102. Suppose. The icon is an example of information corresponding to the first data.

In this case, when the terminal position and the position of the icon on the display screen 102 have a predetermined relationship, the data transmission unit 204 may transmit the predetermined application program to the wireless communication terminal 103 as terminal-corresponding data. Good.

Note that the case where the terminal position and the position of the icon on the display screen 102 are in a predetermined relationship is, for example, when the wireless communication terminal 103 is placed over the icon or near the icon ( An example is when the wireless communication terminal 103 is arranged so that a part of the wireless communication terminal 103 is in contact with a region within a predetermined distance from the icon, or when the wireless communication terminal 103 is placed on the icon. Is done.

Similarly, when an image such as an icon or a thumbnail corresponding to entity data such as a text file stored in the storage unit 206 is displayed on the display screen 102, the terminal position and the image on the display screen 102 are similarly displayed. When the position has a predetermined relationship, the data transmission unit 204 may transmit the entity data to the wireless communication terminal 103 as terminal-corresponding data.

In addition, the data transmission unit 204 may not use the partial area for specifying the terminal-compatible data acquired from the storage unit 206. That is, the terminal corresponding data may be specified using the terminal position specified by the specifying unit 200. That is, the specifying unit 200 may not include the region specifying unit 203.

For example, when one corner of the wireless communication terminal 103 comes into contact with the display screen 102, the specifying unit 200 can specify the terminal position based on the coordinate value of one point corresponding to the contact position on the display screen 102. Further, as described above, the specifying unit 200 determines the coordinate value of any vertex of the polygon forming the placement area 210 (see FIG. 4B) or the coordinate value of the center of gravity of the placement area 210. Etc., the terminal position can be specified.

When the terminal position specified in this way is, for example, in a window where text is displayed, or in an area where an image such as an icon is displayed, or within a predetermined distance from the area, the terminal-corresponding data is It may be transmitted to the wireless communication terminal 103.

In this case, examples of the terminal-corresponding data include at least a part of the sentence, the image data, and an application program or entity data corresponding to the image.

In other words, for example, the user touches a part such as a corner portion of the wireless communication terminal 103 with a desired position in the display screen 102, so that a sentence, an image, an application program, or the like corresponding to the position can be displayed on the terminal. The wireless communication terminal 103 can acquire the corresponding data.

(Embodiment 2)
In the present embodiment, an example of the operation of the information display apparatus 101 when the wireless communication terminal 103 is placed on an icon displayed on the display screen 102 of the information display apparatus 101 will be described.

In the present embodiment, since the operation of the data transmission unit 204 is mainly different from that of the first embodiment, the operation of the data transmission unit 204 will be mainly described.

FIG. 12 is a diagram illustrating an example of the appearance of the information display device 101 and the wireless communication terminal 103 according to the second embodiment.

12, the same reference numerals are given to substantially the same components as those in FIG. 1. Further, the functional configuration of the information display apparatus 101 in the second embodiment is substantially the same as that of the first embodiment (see FIGS. 2 and 3), and thus detailed description thereof is omitted.

As shown in FIG. 12, a plurality of icons are displayed on the display screen 102 of the information display apparatus 101 in the second embodiment. Each icon is selected to call a function set in the icon and start a set program.

In the storage unit 206 in the present embodiment, an icon table, icon data, and a program are stored.

In the icon table, a display position, an icon name, an icon data identifier, and a program identifier corresponding to the icon are recorded for each icon.

The icon data is an example of the first data, and the image (icon image) indicated in the icon data is an example of an image corresponding to a predetermined application program.

The program corresponding to icon data is an example of second data corresponding to first data.

FIG. 13 is a diagram illustrating a data configuration example of the icon table 208 according to the second embodiment.

The icon table 208 shown in FIG. 13 has, as data items, an icon name, an icon data identifier, a display position (coordinate value), and a program identifier.

Note that the icon table 208 may include data items other than the data items shown in FIG. For example, an icon size representing the size of icon display may be recorded in the icon table 208.

Hereinafter, the operation of the information display apparatus 101 according to the second embodiment will be described with reference to FIGS.

FIG. 14 is a flowchart showing an example of the operation of the data transmission unit 204 in the second embodiment.

FIG. 15 is a diagram illustrating a state where the wireless communication terminal 103 according to the second embodiment is placed on the display screen 102 illustrated in FIG.

For example, assume that the wireless communication terminal 103 is placed on the icon 107 displayed on the display screen 102 as shown in FIG. The icon 107 is an icon that activates a predetermined program when selected.

In this case, the information display apparatus 101 performs the same operation as in the first embodiment, and specifies the cutout range (partial area corresponding to the wireless communication terminal 103) on the display screen 102 (see S101 to S106 in FIG. 7).

The data transmission unit 204 determines whether or not the terminal position and the icon 107 are in a predetermined relationship. In the present embodiment, the data transmission unit 204 uses the display position of the icon 107 shown in the icon table 208 to determine whether or not the icon 107 exists in the specified partial area (S1101). .

Note that, when at least a part of the icon 107 exists in the partial area, the data transmission unit 204 determines that the icon 107 exists in the partial area.

When the data transmission unit 204 determines that the icon 107 exists in the partial area (Yes in S1101), the data transmission unit 204 specifies the icon data and the program corresponding to the icon 107 by referring to the icon table 208. The data transmission unit 204 further acquires the specified icon data and program from the storage unit 206 (S1102).

That is, in this case, the icon data is acquired from the storage unit 206 as terminal-corresponding data corresponding to the partial area specified by the area specifying unit 203. That is, icon data that is an example of first data is acquired from the storage unit 206 as terminal-corresponding data.

If the data transmission unit 204 determines that the icon 107 does not exist in the partial area (No in S1101), the data transmission unit 204 performs the same operation as in the first embodiment.

That is, the image data including the icon 107 and the background of the icon 107, which is the image of the partial area specified by the area specifying unit 203, is read from the storage unit 206 as the partial image data (S1103).

The data transmission unit 204 transmits the data acquired from the storage unit 206 to the terminal (wireless communication terminal 103) having the identification information detected by the identification information acquisition unit 202 via the wireless communication interface 207 (S1104).

In the case of FIG. 15, the data transmission unit 204 determines that the icon name is “name1” in the partial area, for example, from the relationship between the display position of the icon table 208 and the partial area specified by the area specifying unit 203. It is determined that a certain icon 107 exists.

In this case, the data transmission unit 204 specifies an icon data identifier “icon_data1” and a program identifier “program1” from the icon table 208. The data transmission unit 204 further reads out icon data and a program corresponding to the identified identifiers from the storage unit 206 and transmits them to the wireless communication terminal 103.

When the data transmitted from the information display device 101 is icon data and a program, the wireless communication terminal 103 records the icon data and the program in association with each other, and displays the icon indicated by the icon data on the terminal screen 104. indicate.

The data transmission unit 204 can also transmit the partial image data acquired by the same processing as in the first embodiment to the wireless communication terminal 103 before transmitting the icon data and the program, for example.

That is, the data transmission unit 204 transmits the image of the partial area including the icon 107 and the background of the icon 107 as the partial image data even when the icon data and the program are transmitted to the wireless communication terminal 103. May be sent to.

As a result, as shown in FIG. 15, the icon 107 apparently displayed on the display screen 102 is displayed on the terminal screen 104 of the wireless communication terminal 103 as it is.

Thereafter, for example, an image (icon 107) indicated by the icon data is selected as an object that can be selected on the terminal screen 104 when a predetermined instruction input of the wireless communication terminal 103 by the user or reception of the icon data is triggered. Is displayed.

FIG. 16 is a diagram illustrating a state in which the wireless communication terminal 103 illustrated in FIG. 15 is moved out of the information display device 101.

As shown in FIG. 16, in FIG. 15, the icon 107 shown in the icon data “icon_data1” displayed in the portion of the display screen 102 where the wireless communication terminal 103 was placed is the terminal screen 104 of the wireless communication terminal 103. Is displayed.

Specifically, the icon 107 is displayed as a selectable object on the terminal screen 104.

In this case, when the icon 107 is selected by the user, the program “program1” corresponding to the icon 107 is started in the wireless communication terminal 103.

It is assumed that “program1”, which is a program corresponding to the icon 107, is copy-prohibited. In this case, the data transmission unit 204 may transmit “icon_data1” and “program1” without transmitting “icon_data1” and “program1” to the wireless communication terminal 103, for example.

In addition, the data transmission unit 204 checks, for example, whether or not the wireless communication terminal 103 has the authority to execute “program1”, and only when the user has the authority to execute “program1”, “icon_data1” And “program1” may be transmitted.

As described above, in the present embodiment, simply by placing the wireless communication terminal 103 on the icon displayed on the information display device 101, the icon data indicating the icon and the program corresponding to the icon are displayed on the terminal. It is possible to transmit the correspondence data and the second data to the wireless communication terminal 103.

Note that the original icon data is not transmitted as the terminal-compatible data, but the icon data after the drawing process is performed may be transmitted. Further, image data including the icon and the background thereof may be transmitted to the wireless communication terminal 103 as the terminal-corresponding data.

Also, the terminal compatible data and the second data need not be transmitted simultaneously.

For example, after transmitting terminal-compatible data (for example, icon data) to the wireless communication terminal 103, the data transmission unit 204 receives second data (for example, a program corresponding to the icon data) in response to a request from the wireless communication terminal 103. May be transmitted to the wireless communication terminal 103.

FIG. 17 is a sequence diagram illustrating an example of the flow of operations of the information display device 101 and the wireless communication terminal 103 according to the second embodiment.

For example, assume that the wireless communication terminal 103 is placed on the icon 107 as shown in FIG. In this case, as described above, the data transmission unit 204 specifies icon data “icon_data1” corresponding to the icon 107 (S1501).

The data transmission unit 204 further acquires “icon_data1” from the storage unit 206 and transmits it to the wireless communication terminal 103 via the wireless communication interface 207 (S1502).

As illustrated in FIG. 16, the wireless communication terminal 103 displays the received icon 107 indicated by “icon_data1” on the terminal screen 104 (S1503).

Thereafter, when the operation of the icon 107 by the user (for example, tapping the icon 107) is detected (S1504), the wireless communication terminal 103 requests transmission of a program corresponding to the icon 107 (S1505).

The data transmission unit 204 identifies “program1”, which is the second data corresponding to the icon 107 (S1506), and transmits “program1” to the wireless communication terminal 103 (S1507).

As described above, the information display apparatus 101 can execute transmission of the second data corresponding to the terminal-corresponding data to the wireless communication terminal 103 in response to a request from the wireless communication terminal 103.

Thereby, for example, when the wireless communication terminal 103 does not actually need to execute “program1”, execution of unnecessary communication (transmission of “program1” to the wireless communication terminal 103) is prevented. The

Further, the terminal correspondence data transmitted from the information display apparatus 101 to the wireless communication terminal 103 and the second data related to the terminal correspondence data are not limited to icon data and programs.

For example, when the wireless communication terminal 103 is placed on an icon associated with a file such as text, audio, still image, or moving image, the file may be transmitted to the wireless communication terminal 103 as second data.

Also, for example, it is assumed that the wireless communication terminal 103 is placed on a thumbnail of a still image or a moving image displayed on the display screen 102. In this case, the thumbnail and the still image or the moving image may be transmitted to the wireless communication terminal 103 as the terminal correspondence data and the second data.

That is, the storage unit 206 stores first data indicating an image (for example, an icon or a thumbnail) associated with entity data (audio, moving image, still image, etc.) to be processed by a predetermined application program, and the entity data May be stored as second data. In this case, the data transmission unit 204 is the second data when the terminal position specified by the specifying unit 200 and the position of the image indicated by the first data on the display screen 102 have a predetermined relationship. The actual data may be acquired from the storage unit 206 and the acquired actual data may be transmitted to the wireless communication terminal 103.

In addition, as a case where the terminal position and the position on the display screen 102 of the image indicated by the first data have a predetermined relationship, for example, the first data indicates the partial area corresponding to the terminal position. A case where at least a part of the image is present is exemplified.

Further, it is assumed that the wireless communication terminal 103 is placed on the two-dimensional barcode in a state where, for example, a two-dimensional barcode indicating a predetermined URL (Uniform Resource Locator) is displayed on the display screen 102. In this case, the two-dimensional barcode image and the URL may be transmitted to the wireless communication terminal 103 as the terminal correspondence data and the second data. That is, the image data of the two-dimensional barcode may be handled as the first data, and the data indicating the URL may be handled as the second data.

Thereby, even if the wireless communication terminal 103 does not have a function of analyzing a two-dimensional barcode, the wireless communication terminal 103 can acquire information such as a URL corresponding to the two-dimensional barcode.

The information display device 101 does not have to transmit information such as a URL corresponding to the two-dimensional barcode when transmitting the image of the two-dimensional barcode to the wireless communication terminal 103. That is, the wireless communication terminal 103 that has received the two-dimensional barcode may acquire information such as the URL by analyzing the two-dimensional barcode.

In each embodiment, a pressure-sensitive detection device is used as the detection unit 201. However, any device other than a pressure-sensitive method can be used as long as the device can detect the position and orientation of a placed object. You may employ | adopt as the detection part 201. FIG.

For example, an infrared detection device using a plurality of infrared sensors 105 may be employed as the detection unit 201.

As shown in FIG. 18, a plurality of infrared sensors 105 are installed around the display screen 102 of the information display device 101, and the position of the wireless communication terminal 103 is detected by detecting blocking of infrared rays output from the plurality of infrared sensors 105. And the orientation may be acquired.

In addition to the infrared method, various methods such as a capacitance method for measuring the capacitance of a human hand and a surface acoustic wave method using vibration by a piezoelectric element are placed on the display screen 102. It can be adopted as a method for detecting the position, orientation, etc.

Further, for example, as shown in FIG. 19A, three protrusions 151a as shown in FIG. 19B are formed on the surface (back surface) opposite to the terminal screen 104 of the wireless communication terminal 103. The adapter 150 having 151b and 151c may be attached.

Note that FIG. 19B shows a state in which the adapter 150 shown in FIG. 19A is turned upside down.

In this case, for example, as shown in FIG. 20A, an XY coordinate system in which the lower left point on the display screen 102 is the origin O (0, 0), the right direction from the origin O is the X axis, and the upper direction is the Y axis. , The positions of the protrusions 151a to 151c are detected.

For example, as shown in FIG. 20B, the coordinates (X1, Y1), (X2, Y2), and (X3, Y3) of the protrusions 151a to 151c are detected by the detection unit 201. The detection unit 201 further compares the triangular shape formed by the preset projecting portions 151a to 151c with the triangular shape formed by the detected three coordinate points on the display screen 102. The position and direction where the wireless communication terminal 103 is placed are detected.

Note that the position and orientation of the wireless communication terminal 103 may be calculated by the area specifying unit 203 acquiring the coordinate values of these three points from the detecting unit 201.

Moreover, the adapter 150 does not need to have three protrusions, and may have at least one protrusion.

FIG. 21 is a diagram showing a method for detecting the position and orientation of the wireless communication terminal 103 with one protrusion.

For example, as shown in FIG. 21A, when an adapter 150 having a protrusion 152 whose surface (contact surface) in contact with the information display device 101 has a triangular shape is attached to the back surface of the wireless communication terminal 103. Is assumed.

In this case, the detection unit 201 can detect the three vertices of the triangle formed by the contact surface shown in FIG. That is, the coordinates (X11, Y11), (X12, Y12), and (X13, Y13) are detected by the detection unit 201.

That is, as in the case shown in FIG. 20, it is possible to detect the position and orientation of the wireless communication terminal 103 using the coordinate values of these three points.

Note that the shape of the contact surface of the protrusion 152 does not need to be a triangle, but the orientation of the wireless communication terminal 103 is unique when it is disposed on the back surface of the wireless communication terminal 103, such as a vertically asymmetrical shape or a laterally asymmetrical shape. It is preferable that an identifiable shape is adopted.

Moreover, the adapter 150 may have a marker that can be detected by the detection unit 201 instead of the protruding portion.

Further, the protruding portion may be arranged directly on the back surface of the wireless communication terminal 103 instead of the adapter 150. That is, if at least one protrusion is provided on the opposite side of the terminal screen 104 of the wireless communication terminal 103, the orientation of the wireless communication terminal 103 can be detected using the at least one protrusion. Is possible.

Also, a geomagnetic sensor may be used for detecting the orientation of the wireless communication terminal 103. For example, it is assumed that both the information display device 101 and the wireless communication terminal 103 are provided with a geomagnetic sensor.

In this case, the orientation of the wireless communication terminal 103 with respect to the information display device 101 from the respective orientations of the information display device 101 and the wireless communication terminal 103 obtained from these geomagnetic sensors (the wireless communication terminal 103 with respect to the information display device 101 in the XY plane). It is possible to calculate (relative angle).

Further, in each embodiment, the detection unit 201 is configured such that the distance between the display screen 102 and the wireless communication terminal 103 is substantially “0” when the wireless communication terminal 103 is placed on the display screen 102. In some cases, the terminal position which is the position of the wireless communication terminal 103 is detected.

However, when the distance between the display screen 102 and the wireless communication terminal 103 is greater than “0”, that is, when the wireless communication terminal 103 and the display screen 102 are in a non-contact state, the detection unit 201 The terminal position that is the position of the communication terminal 103 may be detected.

In this case, the detection unit 201 includes, for example, one transmitter that transmits ultrasonic waves and three or more receivers that receive ultrasonic waves. You may detect the position of the radio | wireless communication terminal 103 arrange | positioned upwards (for example, the Z-axis positive direction in FIG. 4, the same hereafter).

In this case, the detection unit 201 determines whether, for example, the wireless communication terminal 103 is present within a predetermined distance from the display screen 102 from the three-dimensional position of the wireless communication terminal 103 obtained by the three-point surveying. Check. As a result, when the wireless communication terminal 103 exists within a predetermined distance from the display screen 102, the detection unit 201 detects, for example, a plane parallel to the display screen 102 of the wireless communication terminal 103 from the three-dimensional position. The two-dimensional position at is specified. The detection unit 201 further specifies a position on the display screen 102 corresponding to the specified two-dimensional position as the terminal position.

The detection unit 201 includes, for example, one of four corners when the wireless communication terminal 103 is viewed from the top, or a vertical line drawn down from the center point when the wireless communication terminal 103 is viewed from the top to the display screen 102, The coordinates of the intersection point are detected as the terminal position.

In addition, the detection unit 201 hypothesizes a rectangular area as a whole obtained by vertically projecting the back surface of the wireless communication terminal 103 onto the display screen 102 based on the identified two-dimensional positions of the four corners. It may be specified as an appropriate placement area 210 (see FIG. 4). Thereby, for example, the orientation of the wireless communication terminal 103 in a plane parallel to the display screen 102 can be detected.

In addition, the detection unit 201 uses the two-dimensional position or the three-dimensional position of the protrusion or marker provided on the back surface of the wireless communication terminal 103 described with reference to FIGS. The terminal position or the like may be detected.

The terminal position and the like detected in this way are used for specifying terminal-corresponding data as in the above embodiments, and the specified terminal-corresponding data is transmitted to the wireless communication terminal 103.

Although omitted in the above description, when the detection unit 201 detects the presence of an object such as the wireless communication terminal 103 above the display screen 102, for example, an attempt to perform wireless communication with the object and device information (See S102 to S105 in FIG. 7) may be executed.

As described above, the detection unit 201 detects the terminal position of the wireless communication terminal 103 that is in a non-contact state with the display screen 102, so that the wireless communication terminal 103 held over the display screen 102 is moved to the current terminal position. Corresponding partial image data or the like can be transmitted.

Note that the detection unit 201 does not need to confirm whether the wireless communication terminal 103 held over the display screen 102 exists within a predetermined distance from the display screen 102. That is, the detection unit 201 may detect the position of the wireless communication terminal 103 disposed within the detectable range of the detection unit 201 as the terminal position.

Further, the method of detecting the terminal position of the wireless communication terminal 103 in a state of non-contact with the display screen 102 by the detection unit 201 is not limited to the ultrasonic pulse reflection method. For example, the terminal position of the wireless communication terminal 103 that is not in contact with the display screen 102 may be detected based on a time difference between transmission and reception of an optical signal or infrared light.

Further, for example, even when a capacitive touch panel or an infrared touch panel is employed as the detection unit 201, the detection unit 201 can detect the terminal position of the wireless communication terminal 103 that is not in contact with the display screen 102. Detection may be performed.

That is, for example, when the wireless communication terminal 103 is present at a position very close to the touch panel, and the touch panel can roughly detect the position of the wireless communication terminal 103, the detection result is specified as the terminal position. Good.

Further, the detection unit 201 analyzes imaging data obtained by imaging the wireless communication terminal 103, acquires a two-dimensional position or a three-dimensional position of the wireless communication terminal 103 obtained by the analysis as a terminal position. Also good.

In addition, as described above, detection unit 201 has the function of detecting the position of wireless communication terminal 103 that is in non-contact with display screen 102 as the terminal position, as in the first and second embodiments. The function of detecting the position of the wireless communication terminal 103 placed on the display screen 102 as the terminal position may be provided.

For example, it is assumed that the wireless communication terminal 103 is placed on the display screen 102 within a predetermined period after the detection unit 201 detects the position of the wireless communication terminal 103 in a non-contact state with the display screen 102 as the terminal position. To do. In this case, the detection unit 201 may detect the placed position as the final terminal position for the wireless communication terminal 103.

Further, for example, the area specifying unit 203 determines the distance (distance parallel to the Z axis) from the display screen 102 indicated by the three-dimensional position of the wireless communication terminal 103 obtained from the detection unit 201 as 2 The partial region may be specified in consideration of the dimension position.

For example, you may change so that the partial area | region corresponding to a terminal position may become large, so that the wireless communication terminal 103 leaves | separates from the display screen 102. FIG. As a result, for example, by separating the wireless communication terminal 103 placed on the display screen 102 from the display screen 102, it is possible to zoom out an image (for example, see FIG. 9) displayed on the terminal screen 104. Conversely, the image displayed on the terminal screen 104 can be zoomed in by bringing the wireless communication terminal 103 closer to the display screen 102 from a position away from the display screen 102.

Further, as described above, by transmitting the partial image data to the wireless communication terminal 103 that is in a non-contact state with the display screen 102, for example, the following effects can be obtained.

For example, even when the wireless communication terminal 103 does not have a camera, the wireless communication terminal 103 can acquire at least a part of the image displayed on the display screen 102.

At this time, image data for drawing on the display screen 102 of the partial image or image data before being reduced for drawing is transmitted from the information display apparatus 101 to the wireless communication terminal 103 as partial image data. be able to. That is, it is possible to cause the wireless communication terminal 103 to acquire a higher-definition image than an image obtained by imaging.

Also, for example, a case is assumed where the wireless communication terminal 103 has a camera and the two-dimensional barcode displayed on the display screen 102 is photographed by the camera. In this case, generally, if the display screen 102 and the surface of the wireless communication terminal 103 on which the camera is arranged are parallel, the captured two-dimensional barcode image is distorted. In the wireless communication terminal 103, a process for adjusting the camera focus to the two-dimensional barcode is required.

However, in the case of the information display device 101, the display screen 102 and the back surface of the wireless communication terminal 103 do not need to be strictly parallel, and the distortion, blur, and the like are not performed without performing the above focusing process. It is possible to cause the wireless communication terminal 103 to acquire an image of a two-dimensional bar code without an image.

The wireless communication terminal 103 that has acquired the image of the two-dimensional barcode can acquire information such as a URL corresponding to the two-dimensional barcode by analyzing the two-dimensional barcode.

In this case, as described above, information such as a URL corresponding to the two-dimensional barcode may be transmitted from the information display device 101 to the wireless communication terminal 103 as object correspondence data. In this case, the wireless communication terminal 103 does not need a function of analyzing a two-dimensional barcode.

Further, the storage unit 206 may be an HDD or an SSD that can store image data that is a source of an image displayed on the display screen 102, or may be a video memory.

That is, the data transmission unit 204 that acquires and transmits partial image data from the storage unit 206 may acquire partial image data indicating an image before processing such as enlargement or reduction for drawing. You may acquire the partial image data which shows the image after a process was made.

Further, the data transmission unit 204 may selectively acquire partial image data before the processing is performed and partial image data after the processing is performed.

For example, the storage unit 206 stores a first storage unit that stores image data before processing such as enlargement or reduction for drawing, and a drawing image on the display screen 102 after the processing is performed. Suppose that it includes the second storage part that stores data.

Note that the first storage unit is realized by, for example, an HDD or an SSD, and the second storage unit is realized by, for example, a video memory.

In this assumption, for example, image data A having horizontal 3840 pixels and vertical 2160 pixels is stored in the first storage unit, and the image data A is displayed on a display screen having a horizontal resolution of 1920 pixels and vertical 1080 pixels. Assume that the information is displayed on 102.

In this case, in the information display apparatus 101, the image data A read from the first storage unit is subjected to a reduction process according to the screen resolution of the display screen 102, for example, having a horizontal size of 1920 pixels and a vertical size of 1080 pixels. The image data A ′ indicating the image is expanded to the second storage part.

Thereafter, for example, the processing of S101 to S106 shown in FIG. 7 is executed, and the partial area is specified by the area specifying unit 203.

Here, the resolution of the image data A ′ for drawing is lower than the resolution of the original image data A. Therefore, the data transmission unit 204 acquires partial image data corresponding to the partial area from the image data A stored in the first storage unit. In this case, the data transmission unit 204 transmits the partial image data to the wireless communication terminal 103 without performing processing such as reduction or enlargement in accordance with the size and resolution of the terminal screen 104 of the wireless communication terminal 103.

That is, the data transmission unit 204 is stored in the first image data stored in the first storage unit and the second storage unit, which are two image data that can acquire partial image data corresponding to the terminal position. One of the second image data may be selected, and the partial image data may be acquired from the selected second image data.

More specifically, for example, one of the first image data and the second image data may be selected with high resolution, and the partial image data may be acquired from the selected one.

Thus, for example, the wireless communication terminal 103 can acquire partial image data obtained from image data having high resolution image data and maintaining the original resolution.

Further, the above selection may be performed in accordance with an instruction from the wireless communication terminal 103. That is, the data transmission unit 204 may select one of the first image data and the second image data according to an instruction from the wireless communication terminal 103, and acquire partial image data from the selected one.

For example, when the user of the wireless communication terminal 103 wants to transmit partial image data having a small data size from the information display device 101 to the wireless communication terminal 103, an instruction to that effect is sent from the wireless communication terminal 103 to the information display device 101. Send.

In this case, in the above example, the data transmission unit 204 uses the partial image data from the image data A ′ stored in the second storage unit having a lower resolution than the image data A stored in the first storage unit. Is transmitted to the wireless communication terminal 103.

Thereby, for example, the communication load between the information display apparatus 101 and the wireless communication terminal 103 and the load related to the drawing of partial image data in the wireless communication terminal 103 are reduced.

In each embodiment, the transmission destination of the partial image data from the information display device 101 is the wireless communication terminal 103. However, the information display device 101 may transmit the partial image data to the communication terminal via wired communication.

The information display apparatus 101 detects, for example, the position of a communication terminal connected to the information display apparatus 101 with a communication cable as a terminal position, and transmits partial image data corresponding to the partial area specified by the terminal position to the communication cable. Via the communication terminal.

That is, between the information display device 101 and the communication terminal that is the transmission destination of the partial image data, either wired communication or wireless communication may be used, and wired communication and wireless communication may be mixed.

In each embodiment, partial image data is automatically transmitted to a terminal placed on the information display apparatus 101. However, transmission of partial image data may be permitted only to a specific terminal. .

For example, a data item indicating whether or not to allow data transmission is added to the device information table 205, and the information display apparatus 101 may transmit the partial image data only to the permitted terminal.

In this case, when checking whether or not the terminal identification information is registered in the device information table 205, it is also checked whether or not data transmission is permitted. Stop processing.

In addition, for terminals whose identification information is not registered in the device information table 205, an inquiry to an external device such as the server device 801 as described above is not performed, and data transmission may not be permitted.

As described above, according to the information display device 101 in each embodiment, the specifying unit 200 can specify a terminal position that is a position in the display screen 102 of 101 corresponding to the wireless communication terminal 103. Further, the data transmission unit 204 can specify information to be transmitted to the wireless communication terminal 103 from the information held by the information display apparatus 101 using the specified terminal position, and the wireless communication terminal 103 The transmission of the information to can be executed.

In other words, according to the information display device 101, it is possible to easily identify information suitable for the wireless communication terminal 103 disposed within a predetermined distance from the display screen 102 and transmit the information to the wireless communication terminal 103. .

In each of the above embodiments, each component may be configured by dedicated hardware or may be realized by executing a software program suitable for each component. Each component may be realized by a program execution unit such as a CPU or a processor reading and executing a software program recorded on a recording medium such as a hard disk or a semiconductor memory. Here, the software that realizes the information display device of each of the above embodiments is a program as follows.

That is, this program causes the computer to execute the following control method of the information display device.
