(First embodiment)
The first embodiment will be described below with reference to the drawings. FIG. 1A is a schematic configuration diagram of an image display system 1 according to the first embodiment.

The network 9 is a communication infrastructure configured by, for example, a wireless LAN, a mobile phone network, the Internet, or the like.

The server 8 transmits various information to the display device 3. For example, the server 8 transmits a notification image and a connection image indicating connection information for connecting to the display device 3 to the display device 3. The notification image is an image indicating information notified to an unspecified number of people, and is, for example, an advertisement image, a news image, a weather forecast image, or the like. The connection information for connecting to the display device 3 is information indicating a URI (Uniform Resource Identifier), a communication protocol, and the like of the display device 3 necessary for connecting to the display device 3. An example of a connection image is an image of a bar code (for example, a two-dimensional bar code) that expresses connection information, characters and symbols describing the connection information.
The notification image is an example of a visual image (details will be described later) that is an image that is visually recognized by a human. The connection image is an example of a non-viewing image (details will be described later) that are images that are not visible to humans.

  The display device 3 is, for example, an LED display installed on the street (indoor or outdoor). The display device 3 receives and displays the viewing image and the non-viewing image from the server 8. Further, the display device 3 receives and displays a visual image from the electronic device 5. In addition, the image for visual recognition which the display apparatus 3 receives and displays from the electronic device 5 is an image according to operation of the user of the electronic device 5, for example. The image according to the operation of the user of the electronic device 5 is an image (details will be described later) according to the movement path of the main body (housing) of the electronic device 5 or the movement of the main body of the electronic device 5. It is an image that does not follow (does not follow). An example of an image that does not follow the locus of movement of the main body of the electronic device 5 is a splash image (details will be described later).

The electronic device 5 transmits various information to the display device 3. For example, the electronic device 5 transmits a connection request to the unconnected display device 3 and transmits a disconnection request to the connected display device 3. Further, for example, the electronic device 5 transmits drawing information for drawing an image corresponding to a user operation to the connected display device 3.

Send. Details regarding the electronic device 5 will be described later.

  FIG. 2 is an example of a functional block diagram of the display device 3. FIG. 3 is an example of a display signal generated by the display device 3. FIG. 4 is an example of a visual image and a non-visual image.

  As illustrated in FIG. 2, the display device 3 includes a communication unit 10, a control unit 20, and a display unit 30. The control unit 20 includes a conversion unit 22, a timing control unit 24, a distribution unit 26, and a plurality of drive units 28 (28-1, ..., 28-n).

First, the structure of the display unit 30 will be described. As illustrated in FIG. 2, the display unit 30 includes a plurality of pixels 31 (31-1-1,..., 31-nm). Each pixel 31 includes a plurality of light emitting units. Specifically, each pixel 31 includes a red light emitting diode (light emitting diode that emits red light, hereinafter the same), a green light emitting diode (light emitting diode that emits green light, hereinafter the same), and a blue light emitting diode (blue). A light emitting diode (hereinafter, the same applies). For example, as shown in FIG. 2, the pixel 31-n-m is a red _{LED n-m-R} is a light emitting diode, _{LED n-m-G} is a green light-emitting diodes, blue light-emitting diode LED It is composed of _nm-B . The function and operation of the display unit 30 will be described later.

  The communication unit 10 receives various information from the server 8 or the electronic device 5. For example, the communication unit 10 receives from the server 8 a connection image indicating connection information for connecting to the display device 3 as a notification image and a non-viewing image as a viewing image. For example, the communication unit 10 receives a connection request and a disconnection request from the electronic device 5. Further, for example, the communication unit 10 draws, from the electronic device 5, drawing information for drawing an image (details will be described later) according to the movement path of the main body of the electronic device 5 as a visual image, and a splash image (details). Receives drawing information for drawing.

  When the communication unit 10 receives the visual image or the non-visual image from the server 8, the communication unit 10 outputs the visual image or the non-visual image to the conversion unit 22. Further, when the communication unit 10 receives a visual image from the electronic device 5, the communication unit 10 outputs the visual image to the conversion unit 22. Further, when receiving a connection request from the electronic device 5, the communication unit 10 transmits a connection response to the electronic device 5 when permitting the connection. When the communication unit 10 receives a disconnection request from the electronic device 5, the communication unit 10 transmits a disconnection response to the electronic device 5.

  The conversion unit 22 acquires a visual image and a non-visual image from the communication unit 10. The converting unit 22 that has acquired the visual image and the non-visual image causes the visual image to be displayed on the display unit 30 for a time (also referred to as a first display period) in which the human visual response is possible. A display signal (an output signal to the display unit 30) that causes the display unit 30 to display an image for non-viewing is generated during a time when the visual response is not long (also referred to as a second display period). Specifically, according to the control of the timing control unit 24, the conversion unit 22 uses the display signal for the first display period as a display signal representing a visual image, and the display signal for the second display period as a non-visual image. A display signal is generated as a display signal that expresses.

For example, as illustrated in FIG. 3, the conversion unit 22 displays a display signal (A _N : N = 1,... K) for 1/60 seconds every 1/30 second as a display signal representing a visual image. A display signal is generated in which a display signal (B _N : N = 1,... K) for 1/240 seconds every 1/30 second is used as a display signal representing an image for non-viewing. In FIG. 3, 1/30 second is an example of the time of one frame. A _{1, ...,} Each of the A _k, which is a display signal of one frame of the viewing image. Each of B ₁ ,..., B _k is a display signal for one frame of the non-viewing image. 1 / 60th of every 1 / 30th of a second is an example of the first display period. One second of 240th of every 1/30 second is an example of the second display period. In the example of FIG. 3, a part of the time (blank period) other than the first display period in the time of one frame is set as the second display period. The conversion unit 22 outputs the generated display signal to the distribution unit 26.

  The example shown in FIG. 3 shows a display signal that is generated when the conversion unit 22 acquires both the visual image and the non-visual image from the communication unit 10, but the conversion unit 22 When only the non-viewing image is generated, only the display signal (display signal for the first display period) representing the visual image is generated, and when only the non-visual image is acquired, the display representing the non-visual image Only the signal (display signal in the second display period) is generated.

  As described above, the conversion unit 22 uses the display signal for the first display period as a display signal that represents the image for visual recognition, and the display signal for the second display period as a display signal that represents the non-visual image. However, various methods are conceivable for allocating a display signal representing a visual image to the display signal in the first display period and allocating a display signal representing a non-visual image to the display signal in the second display period. . For example, if identification information indicating that the image is a non-visual image is added to the non-visual image, the conversion unit 22 can determine whether the image acquired from the communication unit 10 is a non-visual image. Therefore, according to the control of the timing control unit 24 (timing for non-viewing image), the display signal for the first display period is set as a display signal representing the image for viewing, and the display signal for the second display period is set for non-viewing. A display signal representing an image can be obtained.

  The timing control unit 24 controls the generation timing of the display signal that represents the visual image and the display signal that represents the non-visual image by the conversion unit 22. Specifically, the timing control unit 24 uses the display signal for the first display period as a display signal representing a visual image, and the display signal for the second display period as a display signal representing a non-visual image. Timing information is output to the converter 22 to control the generation timing. For example, the timing control unit 24 uses a display signal for 1/60 second starting from the head every 1/30 second as a display signal representing a visual image, and 5/240 for every 1/30 second. Timing information for converting the display signal for 1/240 seconds starting from 5 seconds (1/60 seconds + 1.5 seconds / 240 seconds) into a display signal that represents a non-viewing image is input to the converter 22. When output, the converter 22 generates the display signal shown in FIG.

  The distribution unit 26 is a shift register, acquires a display signal from the conversion unit 22, distributes the display signal acquired from the conversion unit 22 to each drive unit 28, and outputs it. That is, the distribution unit 26 distributes and outputs a display signal to be output to each pixel 31 to each drive unit 28 that drives each pixel 31. In the example illustrated in FIG. 2, the distribution unit 26 outputs display signals to be output to the pixels 31-1-1 to 31-1-m to the drive unit 28-1,. A display signal to be output to the pixel 31-nm is output to the drive unit 28-n.

  Each drive unit 28 is a driver IC that controls the display unit 30 and drives each pixel 31 included in the display unit 30. Specifically, each drive unit 28 outputs the display signal acquired from the distribution unit 26 to each pixel 31. In the example illustrated in FIG. 2, the drive unit 28-1 outputs the display signal acquired from the distribution unit 26 to the pixels 31-1-1 to 31-1 -m,... The display signals acquired from the distribution unit 26 are output to the pixels 31-n-1 to 31-nm.

  The display unit 30 displays a visual image or a non-visual image transmitted from the server 8 or the electronic device 5 using the plurality of pixels 31. That is, each pixel 31 included in the display unit 30 acquires a display signal representing a visual image or a display signal representing a non-visual image from each driving unit 28, and emits light according to the display signal.

  For example, as shown in FIG. 4A, the display unit 30 displays the weather forecast image transmitted from the server 8 as a visual image. For example, as shown in FIGS. 4B to 4E, the display unit 30 displays a two-dimensional barcode that is a connection image transmitted from the server 8 as a non-viewing image. FIG. 4B shows a display example in which a two-dimensional barcode is displayed over substantially the entire display surface of the display unit 30, and FIG. 4C shows a small two-dimensional barcode in the central region of the display surface of the display unit 30. 4D is a display example in which a two-dimensional barcode is displayed in a region other than the central area of the display surface of the display unit 30, and FIG. 4E is a display example in which the same two-dimensional barcode is displayed on the display surface of the display unit 30. It is the example of a display displayed in multiple numbers. However, as described above, the display time of the non-visual image is a time (second display period) that does not have a length that allows human vision to respond. The code cannot be recognized.

  For example, as shown in FIG. 4F, the display unit 30 displays an image (details will be described later) according to the movement trajectory of the main body of the electronic device 5 transmitted from the electronic device 5 as a visual image. . For example, as shown in FIGS. 4G and 4H, the display unit 30 displays a splash image (details will be described later) transmitted from the electronic device 5 as a visual image. FIG. 4G is a display example of a splash image alone, and FIG. 4H is a display example superimposed on the image of FIG. There are various display modes for the splash image (details will be described later), but details will be described later.

  FIG. 5 is an example of a functional block diagram of the electronic device 5. FIG. 6 is an explanatory diagram relating to imaging of the display unit 30 by the electronic device 5. As shown in FIG. 5, the electronic device 5 includes a display / operation receiving unit 100, an imaging unit 110, an acceleration sensor 120, a drawing control unit 140, and a communication unit 150. The electronic device 5 includes a decoding unit (not shown) that determines whether or not a two-dimensional barcode is captured in the captured image and decodes (decodes) information indicated by the two-dimensional barcode. Note that the distance measuring unit 130 indicated by a broken line in FIG. 5 will be described later.

  The drawing control unit 140 includes a movement amount calculation unit 142, a drawing information generation unit 144, a current position storage unit 146, and a splash image information storage unit 148, and the display unit of the display device 3 that is connected via the communication unit 150. Controls drawing for 30. For example, when the acceleration sensor 120 detects an acceleration other than the approaching direction to the display unit 30, the drawing control unit 140 is an image according to the locus of the main body of the electronic device 5 calculated based on the acceleration (details will be described later). The drawing information for drawing is generated, and the drawing information is transmitted to the display device 3 via the communication unit 150, thereby controlling the drawing on the display unit 30. For example, when the acceleration sensor 120 detects acceleration in the approaching direction to the display unit 30, the drawing control unit 140 generates drawing information for drawing a splash image (details will be described later), and the drawing information Is transmitted to the display device 3 via the communication unit 150 to control drawing on the display unit 30. Details of the movement amount calculation unit 142, the drawing information generation unit 144, the current position storage unit 146, and the splash image information storage unit 148 will be described later.

The display / operation receiving unit 100 is a liquid crystal touch display and provides a user interface. The display / operation receiving unit 100 displays the captured image captured by the imaging unit 110 to the user. In addition, the display / operation receiving unit 100 receives a connection operation for connecting to the display device 3 from the user. When receiving the connection operation from the user, the display / operation receiving unit 100 notifies the communication unit 150 that a connection request should be transmitted to the display device 3.
For example, when the captured image captured by the imaging unit 110 is a two-dimensional barcode indicating connection information for connecting to the display device 3, the display / operation receiving unit 100 displays the two-dimensional barcode. Furthermore, when the connection operation from the user is accepted, the communication unit 150 is notified that the connection request should be transmitted to the display device 3 together with the connection information decoded by the decoding unit (not shown). The display / operation receiving unit 100 may display the connection information decoded by the decoding unit (not shown) when displaying the two-dimensional barcode.

  In addition, the display / operation receiving unit 100 receives a disconnection operation for disconnecting the connection with the display device 3 from the user. The display / operation receiving unit 100 notifies the communication unit 150 that the disconnection request should be transmitted to the display device 3 when the disconnection operation is received from the user.

  Further, when the display / operation receiving unit 100 notifies the communication unit 150 that a connection request should be transmitted to the display device 3 and then obtains a connection response from the communication unit 15, the display / operation receiving unit 100 displays that the drawing mode has been set. In addition, the acceleration sensor 120 is notified that the drawing mode is set. Similarly, when the display / operation receiving unit 100 notifies the communication unit 150 that a disconnection request should be transmitted to the display device 3 and then obtains a disconnection response from the communication unit 15, the display / operation receiving unit 100 is not in a drawing mode (hereinafter referred to as normal mode). Mode), and the acceleration sensor 120 is notified that the normal mode has been set.

  The imaging unit 110 is a camera unit that images a subject and has a continuous shooting (continuous imaging) function. Note that the continuous shooting function is activated by, for example, a user's explicit operation via the display / operation receiving unit 100, and in the present embodiment, the number of continuous shooting is 4 (exposure time is 1/120 second each). Shall.

The imaging unit 110 outputs a captured image to the display / operation receiving unit 100 when imaging a subject (one or four continuous shooting) according to a user instruction. For example, the imaging unit 110 is displaying a display device that is displaying an image (a weather forecast image that is a visual image and a two-dimensional barcode that is a non-visual image) based on the display signal as illustrated in FIG. When the three display units 30 are continuously shot, four captured images as shown in FIG. 6B or 6C are output to the display / operation receiving unit 100. That is, from the display timing of the weather forecast image and the two-dimensional barcode on the display unit 30 and the exposure timing of the imaging unit 110, for example, in continuous shooting P, the weather forecast image is 1 as shown in FIG. The second captured image P ₁ , the second captured image P ₂ , and the fourth captured image P ₄ are captured, and the two-dimensional barcode is captured in the _third captured image P ₃ . Further, the continuous shooting Q, as shown in FIG. 6 (c), two-dimensional bar code is captured at first captured image Q _1, captured images Q ₂ of the weather forecast image _2nd, 3rd The captured image Q ₃ and the fourth captured image Q ₄ are captured.

That is, by continuously shooting the display unit 30 using the electronic device 5, it is possible to recognize a non-visual image that does not need to be recognized visually. More specifically, if the display timing of the viewing image and the non-viewing image on the display unit 30 and the exposure timing of the imaging unit 110 are appropriately set, at least of the plurality of continuously captured images. Since one sheet is a captured image obtained by capturing only the non-viewing image (the above-described captured image P ₃ , captured image Q ₁ ), the non-viewing image is reliably (ie, not superimposed on the viewing image). Be able to recognize. That is, the electronic device 5 can obtain connection information to the display device 3.

  A setting will be described in which at least one of a plurality of continuously captured images is a captured image obtained by capturing only a non-viewing image. For example, in the display device 3, when the second display period is set at a time centered on the middle of the blank period, in the electronic device 5, each exposure time is set so as to be less than half the blank period, The number of continuous shots may be set so that the total exposure time is equal to or longer than the time of one frame. For example, in the example illustrated in FIG. 6A, in the display device 3, a time centering around 1/120 second from the start of the blank period in the middle of the blank period that is 1/60 second (the blank period). Since the second display period is set from 1.5 seconds after 240 seconds to 1/240 seconds after 2.5 seconds after 240 seconds) from the start timing, each exposure time is set in the electronic device 5. Is set to 1 / 120th of a second, and four continuous shots are set.

  Returning to FIG. 5, the acceleration sensor 120 detects the acceleration applied to the main body of the electronic device 5. For example, while the acceleration sensor 120 is set in the drawing mode (from the time when the display / operation receiving unit 100 is notified that the drawing mode is set to the time when it is notified that the normal mode is set) ), The acceleration applied to the main body of the electronic device 5 is detected. When the acceleration sensor 120 detects acceleration applied to the main body of the electronic device 5, the acceleration sensor 120 outputs acceleration information indicating the detected acceleration to the movement amount calculation unit 142.

  The movement amount calculation unit 142 acquires acceleration information from the acceleration sensor 120. When the acceleration information is acquired from the acceleration sensor 120, the movement amount calculation unit 142 calculates the movement amount (direction and size) of the main body of the electronic device 5 based on the acceleration information. When calculating the movement amount of the main body of the electronic device 5, the movement amount calculation unit 142 outputs movement amount information indicating the calculated movement amount to the drawing information generation unit 144.

  The drawing information generation unit 144 acquires movement amount information from the movement amount calculation unit 142. When the movement amount information is acquired from the movement amount calculation unit 142, the drawing information generation unit 144 generates drawing information to be displayed on the display unit 30 of the connected display device 3.

Specifically, when the drawing information generation unit 144 acquires movement amount information other than the approaching direction to the display unit 30 from the movement amount calculation unit 142, the movement trajectory of the main body of the electronic device 5 obtained from the movement amount information. Drawing information (for example, information defining a curve, a straight line, a filled region, a color, etc.) for drawing an image according to the above is generated. More specifically, the drawing information generation unit 144 is drawing information for drawing an image according to the movement trajectory of the main body of the electronic device 5 obtained from the movement amount information, and is displayed on the display device 3 being connected. Drawing information starting from the current designated position (cursor position) in the unit 30 is generated.
Note that the current indicated position on the display unit 30 of the connected display device 3 is stored in the current position storage unit 146 (details will be described later).

  In addition, when the drawing information generation unit 144 acquires the movement amount information in the approaching direction from the movement amount calculation unit 142 to the display unit 30, the drawing information for drawing a splash image representing the splash (for example, a curve, a straight line) , Information that defines the painted area, color, etc.). Specifically, the drawing information generation unit 144 processes (for example, translates and rotates) a drawing information template for drawing a splash image, which is stored in the splash image information storage unit 148, and is connected. Drawing information for drawing a splash image centered on the current designated position on the display unit 30 of the display device 3 is generated. Examples of the approaching direction to the display unit 30 include a direction in which the main body of the electronic device 5 is swung down toward the display unit 30 and a direction in which the main body of the electronic device 5 is projected toward the display unit 30.

  Note that the drawing information generation unit 144 may generate drawing information for drawing a splash image in consideration of the movement amount (acceleration) in the approach direction. That is, the drawing information generation unit 144 generates drawing information for drawing a splash image having a larger size as the movement amount increases. Specifically, the drawing information generation unit 144 processes (for example, translates, rotates, enlarges, reduces) a drawing information template for drawing a splash image, which is stored in the splash image information storage unit 148. Then, drawing information for drawing a splash image having a size corresponding to the amount of movement in the approaching direction centered on the current indicated position on the display unit 30 of the connected display device 3 is generated.

  The drawing information generation unit 144 draws drawing information to be displayed on the display unit 30 of the connected display device 3 (drawing information for drawing an image according to the movement path of the main body of the electronic device 5 or a splash image). Generated drawing information) is generated, the generated drawing information is output to the communication unit 150.

  The current position storage unit 146 stores the current designated position on the display unit 30 of the connected display device 3. Note that the current indication position stored in the current position storage unit 146 is set to an initial position (for example, the center of the display surface) when connected to the display device 3, and the drawing information generation unit 144 sets the movement amount calculation unit 142. Is updated by the drawing information generation unit 144 every time the movement amount information is acquired from.

  The splash image information storage unit 148 stores a drawing information template for drawing a splash image (for example, information defining a curve, a straight line, a filled region, a color, and the like).

  The communication unit 150 acquires a notification from the display / operation receiving unit 100 that a connection request should be transmitted to the display device 3. For example, the communication unit 150 obtains a notification from the display / operation receiving unit 100 that the connection request should be transmitted to the display device 3 together with the connection information indicated by the two-dimensional barcode imaged by the imaging unit 110. To do. The communication unit 150 transmits a connection request to the display device 3 when receiving a notification that the connection request should be transmitted from the display / operation receiving unit 100 to the display device 3. For example, the communication unit 150 transmits a connection request to the display device 3 in accordance with the connection information acquired from the display / operation receiving unit 100.

  Further, the communication unit 150 receives a connection response from the display device 3 that has transmitted the connection request. When receiving a connection response from the display device 3, the communication unit 150 outputs the connection response to the display / operation receiving unit 100.

  In addition, the communication unit 150 acquires a notification from the display / operation receiving unit 100 that a disconnect request should be transmitted to the display device 3. The communication unit 150 transmits a disconnection request to the display device 3 when receiving a notification that the disconnection request should be transmitted to the display device 3 from the display / operation receiving unit 100.

  In addition, the communication unit 150 receives a disconnection response from the display device 3 that has transmitted the disconnection request. When the communication unit 150 receives a disconnection response from the display device 3, the communication unit 150 outputs the disconnection response to the display / operation receiving unit 100.

  The communication unit 150 also displays drawing information (drawing information for drawing an image in accordance with the movement path of the main body of the electronic device 5, to be displayed on the display unit 30 of the connected display device 3 from the drawing information generation unit 144. Or, drawing information for drawing a splash image) is acquired. The communication unit 150 that has acquired the drawing information transmits the drawing information to the display device 3.

For example, an image as shown in FIG. 4F is displayed on the unit 30 as a visual image.
When the communication unit 150 acquires drawing information for drawing a splash image from the drawing information generation unit 144 and transmits the drawing information to the display device 3, the display unit 30 of the display device 3 displays, for example, FIG. ) An image as shown in (f) is displayed as a visual image.

  Hereinafter, the process flow of the image display system 1 will be described. FIG. 7 is a flowchart illustrating an example of the operation of the image display system 1. 8 and 9 are explanatory diagrams for explaining an example of the operation of the image display system 1. Note that the flowchart on the left side of FIG. 7 represents the operation of the display device 3, and the flowchart on the right side of FIG. Note that, at the time of disclosure of the flowchart illustrated in FIG. 7, it is assumed that the display timing of the visual image and the non-visual image on the display unit 30 and the exposure timing of the imaging unit 110 are appropriate. In FIG. 7, the broken line between the left and right flowcharts represents the linkage between the left and right flowcharts, and the dashed-dotted rectangle surrounding a part of the right flowchart indicates that the electronic device 5 is set to the drawing mode. Represents.

  In the flowchart on the left side of FIG. 7, the display device 3 receives from the server 8 a weather forecast image as a visual image and a two-dimensional barcode for connecting to the display device 3 as a non-visual image. (Step S10). For example, as illustrated in FIG. 8A, the display device 3 displays the weather forecast image received from the server 8 on the display unit 30 as a visual image and displays the two-dimensional barcode received from the server 8 for non-visual recognition. The image is displayed on the display unit 30 (step S12). However, the display time of the two-dimensional barcode that is a non-visual image is a second display period that is not long enough for human vision to respond (in the example of FIG. 8A, 1/30 second). Therefore, it cannot be visually recognized.

  Subsequent to step S12, the display device 3 determines whether a connection request is received from the electronic device 5 (step S14). In step S14, when the display device 3 determines that a connection request has not been received from the electronic device 5 (step S14: No), the flowchart of the display device 3 (the flowchart on the left side) ends and restarts from step S10. To do.

  In the flowchart on the right side of FIG. 7, the electronic device 5 determines whether or not a two-dimensional barcode has been acquired (imaged) (step S40). As described above, since the display timing of the visual image and the non-visual image on the display unit 30 and the exposure timing of the imaging unit 110 are appropriate, as shown in FIG. When the display unit 30 displaying the weather forecast image that is a visual image and the two-dimensional barcode that is a non-visual image is captured (continuous shooting), the electronic device 5 can display, for example, FIG. ), Since the two-dimensional barcode is captured on at least one of the four captured images 1 to 4 (captured image 3), the two images are captured from the one (captured image 3). Dimension barcode can be acquired.

  In step S40, when it is determined that the electronic device 5 has not acquired a two-dimensional barcode (step S40: No), that is, when the user has not imaged (continuous shooting) the display unit 30, the electronic device 5 (The flowchart on the right side) ends and restarts from step S40.

  On the other hand, when it is determined in step S40 that the electronic device 5 has acquired the two-dimensional barcode (step S40: Yes), that is, when the user images the display unit 30 (continuous shooting), the electronic device 5 The two-dimensional barcode is displayed on the display / operation receiving unit 100 (step S42).

  Subsequent to step S42, the electronic device 5 determines whether or not a connection operation has been received from the user as shown in FIG. 9A (step S44). In step S44, when it is determined that the electronic device 5 has not received a connection operation from the user (step S44: No), that is, an operation other than the connection operation (for example, a cancel operation) while the two-dimensional barcode is displayed. Is determined to have been accepted, the flowchart of the electronic device 5 (the flowchart on the right side) ends and restarts from step S40.

  On the other hand, when it is determined in step S44 that the electronic device 5 has received a connection operation from the user (step S44: Yes), the electronic device 5 is connected to the display device 3 according to the connection information indicated by the two-dimensional barcode. A connection request is transmitted (step S46).

  When the display device 3 determines in step S14 in the flowchart on the left side of FIG. 7 that a connection request has been received from the electronic device 5 (step S14: Yes), the display device 3 transmits a connection response to the electronic device 5. (Step S16).

  In step S46 of the flowchart on the right side of FIG. 7, the electronic device 5 that has transmitted the connection request to the display device 3 receives the connection response from the display device 3, and shifts from the normal mode to the drawing mode. The electronic device 5 that has shifted to the drawing mode determines whether or not the acceleration sensor 120 detects an acceleration applied to the main body of the electronic device 5 other than the approaching direction to the display unit 30 (step S48). ). As illustrated in FIG. 9B, when the user swings the electronic device 5 up, down, left, and right, the electronic device 5 determines that an acceleration other than the approaching direction to the display unit 30 has been detected.

  In step S48, when the electronic device 5 determines that the acceleration applied to the main body of the electronic device 5 and detected an acceleration other than the approaching direction to the display unit 30 (step S48: Yes), the electronic device 5 Then, drawing information for drawing an image according to the movement trajectory of the main body of the electronic device 5 is transmitted to the display device 3 as a visual image (step S50). On the other hand, when the electronic device 5 determines in step S48 that the acceleration applied to the main body of the electronic device 5 has not been detected other than the approaching direction to the display unit 30 (step S48: No). Step S50 is skipped and the process proceeds to step S52.

  Following step S50 or step S48 (No), the electronic device 5 has detected whether the acceleration sensor 120 detects the acceleration applied to the main body of the electronic device 5 in the approaching direction to the display unit 30. Is determined (step S52). For example, as illustrated in FIG. 9C, when the user swings down the electronic device 5 toward the display unit 30, the electronic device 5 determines that the acceleration in the approaching direction to the display unit 30 has been detected.

  In step S52, when the electronic device 5 determines that the acceleration applied to the main body of the electronic device 5 and the acceleration in the approaching direction to the display unit 30 is detected (step S52: Yes), the electronic device 5 Drawing information for drawing the splash image is transmitted to the display device 3 as a visual image (step S54). On the other hand, when the electronic device 5 determines in step S52 that the acceleration applied to the main body of the electronic device 5 is not detected and the acceleration in the approaching direction to the display unit 30 is not detected (step S52: No), Step S54 is skipped and the process proceeds to step S56.

  Subsequent to step S54 or step S52 (No), the electronic device 5 determines whether or not a cutting operation has been received from the user (step S56). In step S56, when it is determined that the electronic device 5 has not received a cutting operation from the user (step S56: No), the electronic device 5 returns to step S48.

  On the other hand, when it is determined in step S56 that the electronic device 5 has received a cutting operation from the user (step S56: Yes), the electronic device 5 transmits a cutting request to the display device 3 (step S58). The electronic device 5 that has transmitted the disconnection request receives a disconnection response from the display device 3, shifts from the drawing mode to the normal mode, ends the flowchart of the electronic device 5 (the flowchart on the right side), and restarts from step S40.

  In step S <b> 16 of the flowchart on the left side of FIG. 7, the display device 3 that has transmitted the connection response to the electronic device 5 draws drawing information (drawing an image according to the movement path of the main body of the electronic device 5) from the electronic device 5. It is determined whether or not drawing information (drawing information for drawing a splash image) has been received (step S18).

  In step S18, when it is determined that the display device 3 has received the drawing information from the electronic device 5 (step S18: Yes), the display device 3 uses an image based on the drawing information received from the electronic device 5 as a visual image. It is displayed on the display unit 30. Therefore, for example, as shown in FIG. 9B, when the user swings the electronic device 5 up, down, left, and right, an image according to the movement path of the main body of the electronic device 5 is displayed as a visual image. When the user swings down the electronic device 5 toward the display unit 30 as shown in FIG. 9C, a splash image is displayed on the display unit 30 as a visual image.

  On the other hand, if the display device 3 determines in step S18 that drawing information has not been received from the electronic device 5 (step S18: No), it skips step S20 and proceeds to step S22.

  Subsequent to step S20 or step S18 (No), the display device 3 determines whether or not a disconnection request has been received from the electronic device 5 (step S22). In step S22, when the display device 3 determines that a disconnection request has not been received from the electronic device 5 (step S22: No), the display device 3 returns to step S18.

  On the other hand, when the display device 3 determines in step S22 that the disconnection request has been received from the electronic device 5 (step S22: Yes), the display device 3 transmits a disconnection response to the electronic device 5 (step S24). The flowchart of the display device 3 (the flowchart on the left side) ends, and restarts from step S10.

That is, when the current indication position is in the left area and the main body of the electronic device 5 is swung down straight toward the display unit 30, the drawing information generation unit 144 of the electronic device 5 The drawing information of a straight and small splash image is generated around the left area (the center position of the left area).

  FIG. 10E shows that when the image shown in FIG. 10A is displayed on the display unit 30 and the current designated position (cursor position) exists in the central area, the user This is a display example of the display unit 30 when the main body of the device 5 is slightly swung down from the upper right to the lower left toward the display unit 30. That is, when the current indication position is in the central area, the electronic device 5 is slightly swung down from the upper right to the lower left toward the display unit 30. The drawing information generation unit 144 generates drawing information of a small splash image in the diagonal direction from the upper right to the lower left with the central region as the center. The oblique splash image is a splash image obtained by rotating a template stored in the splash image information storage unit 148.

In this case, as illustrated in FIG. 10G, the drawing information generation unit 144 of the electronic device 5 is configured so that the splash image when the second swing is performed does not overlap with the splash image when the first swing is performed. You may generate | occur | produce the drawing information of the splash image at the time of the downward swing.

  In the example shown in FIG. 10A, the display unit 30 is divided into three regions (left region, center region, and right region) in the horizontal direction (left and right direction). It is not limited to. For example, the display unit 30 may be divided into n in the horizontal direction and m in the vertical direction.

Note that the user may appropriately select one type of splash image to be drawn on the display device 3 via the display / operation receiving unit 100, but depending on the drawing item (pen, brush, brush), the display device One type of splash image to be drawn in 3 may be automatically selected. Also, one type of splash image to be drawn on the display device 3 may be selected at random.

  Moreover, the electronic device 5 is good also as a structure further provided with the distance measurement part 130 which measures the distance of the main body of the electronic device 5, and a target object, as shown with a broken line in FIG. When measuring the distance to the display unit 30 (display surface) of the display device 3, the distance measurement unit 130 outputs distance information indicating the measured distance to the drawing information generation unit 144. Note that the distance measurement unit 130 may measure the distance to the display unit 30 while the drawing mode is set, as with the acceleration sensor 120.

  When the electronic device 5 includes the distance measurement unit 130, the drawing information generation unit 144 that has acquired the distance information indicating the distance from the distance measurement unit 130 to the display unit 30 of the display device 3 considers the distance information and connects Drawing information to be displayed on the display unit 30 of the display device 3 is generated. For example, the drawing information generation unit 144 generates drawing information having a smaller size as the display unit 30 approaches the display unit 30.

  Specifically, when the drawing information generation unit 144 acquires movement amount information other than the approaching direction to the display unit 30 from the movement amount calculation unit 142, the movement trajectory of the main body of the electronic device 5 obtained from the movement amount information.

The composition ratio of the light emitting diode and the infrared light emitting diode may not be 1: 1: 1: 1.

  The communication unit 40 receives various types of information from the server 8 or the electronic device 5 as with the communication unit 10 included in the display device 3 of the image display system 1. That is, for example, the communication unit 40 receives from the server 8 a connection image indicating connection information for connecting to the display device 4 as a notification image and a non-viewing image as a viewing image. For example, the communication unit 40 receives a connection request and a disconnection request from the electronic device 5. Further, for example, the communication unit 40 draws from the electronic device 5 drawing information for drawing an image according to the movement trajectory of the main body of the electronic device 5 as drawing image, and drawing information for drawing a splash image.

When the communication unit 40 receives a disconnection request from the electronic device 5, the communication unit 40 transmits a disconnection response to the electronic device 5.

  The conversion unit 52 acquires a visual image and a non-visual image from the communication unit 40. The conversion unit 52 that has acquired the image for visual recognition and the image for non-visual recognition causes the first light emitting unit (red light emitting diode, green light emitting diode, blue light emitting diode) to display the visual image, and the second light emitting unit (infrared ray). A display signal (an output signal to the display unit 60) for displaying a non-viewing image on the light emitting diode) is generated. Specifically, the conversion unit 52 is a display signal (hereinafter, also referred to as an RBG display signal) that causes a display signal representing a visual image to be displayed using the first light emitting unit in accordance with the control of the timing control unit 54. Then, a display signal that generates a display signal that represents the non-viewing image using the second light emitting unit (hereinafter also referred to as an Ir display signal) is generated.

For example, as shown in FIG. 13, the conversion unit 52 expresses a display image for RGB with a display signal for RGB (C _N : N = 1,... K) for 1/60 seconds every 30 seconds. A display signal is generated using a display signal as a display signal that represents a non-viewing image with another 1/60 second display signal (D _N : N = 1,... K) every 30 seconds. To do.

Each of D ₁ ,..., D _k is a display signal for one frame of the non-viewing image. Further, B _1, ..., the time B _k, a time corresponding to the blank period in the first embodiment. That is, in the example of FIG. 13, the entire time corresponding to the blank period is the time of the Ir display signal.
However, the entire time corresponding to the blank period may not be the time of the Ir display signal (a part of the time corresponding to the blank period may be the time of the Ir display signal). The conversion unit 52 outputs the generated display signal to the distribution unit 56.

  The example shown in FIG. 13 shows a display signal when the conversion unit 52 acquires both the image for viewing and the image for non-viewing from the communication unit 40, but the conversion unit 52 displays only the image for viewing. When acquired, only a display signal representing the image for visual recognition is generated, and when only an image for non-visual recognition is acquired, only a display signal representing the image for non-visual recognition is generated. In addition, when always generating only a display signal representing a non-visual image, the pixel 61 may be configured by only an infrared light emitting diode (second light emitting unit).

  As described above, the conversion unit 52 uses the display signal representing the visual image as the RBG display signal and the display signal representing the non-visual image as the Ir display signal, but the RBG display signal. Various methods are conceivable for assigning the display signal representing the image for visual recognition to the image and assigning the display signal representing the non-visual image to the Ir display signal. For example, if identification information indicating that the image is a non-visual image is added to the non-visual image, the conversion unit 52 can determine whether the image acquired from the communication unit 40 is a non-visual image. Therefore, in accordance with the control of the timing control unit 54 (the timing of the Ir display signal), the display signal representing the visual image is used as the RBG display signal, and the display signal representing the non-visual image is used as the Ir display signal. can do.

  The timing control unit 54 controls the generation timing of the display signal that represents the visual image and the display signal that represents the non-visual image by the conversion unit 52. Specifically, the timing control unit 54 converts timing information for converting a display signal representing a visual image into an RBG display signal and a display signal representing a non-visual image into an Ir display signal. And the generation timing is controlled. For example, the timing control unit 54 uses a display signal for 1/60 second starting from the head every 1/30 second as a display signal for RBG expressing a visual image, and 60 minutes every 1/30 second. When the timing information for converting the display signal for 1/60 second starting from 1 second to Ir display signal representing the image for non-viewing to the conversion unit 52 is output to the conversion unit 52 in FIG. A display signal as shown is generated.

  The distribution unit 56 is a shift register, acquires a display signal from the conversion unit 52, distributes the display signal acquired from the conversion unit 52 to each drive unit 58, and outputs it. That is, the distribution unit 56 distributes and outputs a display signal to be output to each pixel 61 to each drive unit 58 that drives each pixel 61. In the example illustrated in FIG. 11, the distribution unit 56 outputs a display signal to be output to the pixels 61-1-1 to 61-1-m to the drive unit 58-1,. A display signal to be output to the pixel 61-nm is output to the drive unit 58-n.

  Each drive unit 58 is a driver IC that controls the display unit 60 and drives each pixel 61 included in the display unit 60. Specifically, each driving unit 58 outputs the RGB display signal acquired from the allocating unit 56 to the first light emitting unit constituting each pixel 61 of each output destination, and each pixel 61 of each output destination. The Ir display signal acquired from the allocating unit 56 is output to the second light emitting unit configuring the above. In the example illustrated in FIG. 11, the drive unit 58-1 outputs RGB display signals to the first light emitting units that constitute the pixels 61-1-1-1 to 61-1-m, and the pixel 61- 1-1 to the pixel 61-1-m, the Ir display signal is output to the second light-emitting unit constituting each pixel 61, and the driving unit 58-n includes the pixel 61-n-1 to the pixel 61-n. RGB display signals are output to the first light emitting units constituting the respective pixels 61 of −m, and Ir display is performed on the second light emitting units constituting the respective pixels 61 of the pixels 61-n-1 to 61-nm. Output a signal.

  As described above, each drive unit 58 outputs an RGB display signal to the first light emitting unit and outputs an Ir display signal to the second light emitting unit, but allocates an RGB display signal to the first light emitting unit. Various methods are conceivable for the control of allocating the Ir display signal to the second light emitting unit. One example is a method using synchronization. Specifically, for example, if the timing control unit 54 outputs timing information (for example, timing information for a visual image) to each driving unit 58, each driving unit 58 is based on the timing information. An RGB display signal can be output to the first light emitting unit, and an Ir display signal can be output to the second light emitting unit. Another example is a method of adding control information to a display signal. Specifically, the conversion unit 52 adds a determination signal for determining the allocation destination to the RGB display signal, and the determination is also performed in each display signal after the distribution unit 56 distributes to each drive unit 58. If the signal remains, each driving unit 58 can output an RGB display signal to the first light emitting unit and an Ir display signal to the second light emitting unit based on the determination signal. .

  The display unit 60 displays a visual image or a non-visual image transmitted from the server 8 or the electronic device 5 using the plurality of pixels 61. That is, each pixel 61 included in the display unit 60 receives, from each drive unit 58, a display signal (RGB display signal) representing a visual image or a display signal (Ir display signal) representing a non-visual image. And emits light according to the display signal.

  For example, as shown in FIG. 4A, the display unit 60 displays the weather forecast image transmitted from the server 8 as a visual image. For example, as shown in FIGS. 4B to 4E, the display unit 60 displays a two-dimensional barcode that is a connection image transmitted from the server 8 as a non-visual image. However, as described above, since the non-viewing image is displayed using the light emitting unit (second light emitting unit) that emits invisible light, the two-dimensional barcode that is the non-viewing image is visually recognized. I can't.

  Further, for example, as shown in FIG. 4F, the display unit 60 displays an image according to the movement trajectory of the main body of the electronic device 5 transmitted from the electronic device 5 as a visual image. In addition, for example, as shown in FIGS. 4G and 4H and FIGS. 10C to 10G, the display unit 60 displays the splash image transmitted from the electronic device 5 as a visual image. To do.

  FIG. 14 is an explanatory diagram relating to imaging of the display unit 60 by the electronic device 5. Specifically, as shown in FIG. 13, FIG. 14 shows a display signal in which a display signal representing a visual image is an RGB display signal, and a display signal representing a non-visual image is an Ir display signal. It is explanatory drawing regarding the imaging of the display part 60 by the electronic device 5 at the time of producing | generating.

The imaging unit 110 of the electronic device 5 is displaying images (a weather forecast image that is a visual image and a two-dimensional barcode that is a non-visual image) based on the display signal as illustrated in FIG. When the display unit 60 of the display device 4 is continuously shot, four captured images as shown in FIG. 14B or FIG. 14C are output to the display / operation receiving unit 100. That is, from the display timing of the weather forecast image and the two-dimensional barcode on the display unit 60 and the exposure timing of the imaging unit 110, for example, in continuous shooting R, as shown in FIG. The first captured image R ₁ is captured, the weather forecast image and the two-dimensional barcode are captured in the _second captured image R ₂ , and the fourth captured image R ₄ , and the two two-dimensional barcodes are captured. It is captured in the captured image R ₃ eyes. Further, in the continuous shooting S, as shown in FIG. 14C, a two-dimensional barcode is captured in the _first captured image S ₁ and the second captured image S ₂ , and the weather forecast image is 3 Images are captured in the first captured image S ₃ and the fourth captured image S ₄ .

That is, by continuously shooting the display unit 60 using the electronic device 5, it is possible to recognize a non-visual image that does not need to be recognized visually. More specifically, if the display timing of the viewing image and the non-viewing image on the display unit 60 and the exposure timing of the imaging unit 110 are appropriately set, at least of the plurality of continuously captured images. Since one image is a captured image obtained by capturing only the non-visual image (the captured image R ₃ , the captured image S ₁ , and the captured image S ₂ described above), the non-visual image is reliably (that is, the visual image and (Without superimposition). That is, the electronic device 5 can obtain connection information to the display device 4.

  A setting will be described in which at least one of a plurality of continuously captured images is a captured image obtained by capturing only a non-viewing image. For example, in the display device 4, when the Ir display signal is set at a time centered on the middle of the period corresponding to the blank period in the first embodiment, in the electronic device 5, half of the period corresponding to the blank period. Each exposure time may be set so as to be the following time, and the number of continuous shots may be set so that the total of each exposure time is equal to or more than one frame time. For example, in the example shown in FIG. 14A, since the display signal for Ir is set for the entire period corresponding to the blank period in the display device 4, each exposure time is set to 1/120 in the electronic device 5. The second is set to 4 seconds.

  FIG. 15 is another example of the display signal generated by the display device 4. As illustrated in FIG. 13, the conversion unit 52 generates a display signal in which a display signal representing a visual image is an RGB display signal, and a display signal representing a non-visual image is an Ir display signal. Instead, as shown in FIG. 15, a display signal representing a visual image and a display signal representing a non-visual image are RGB display signals, and a display signal representing a non-visual image is an Ir display signal. A display signal may be generated. That is, the timing control unit 54 uses the display signal representing the visual image and the display signal representing the non-visual image as the RBG display signal, and the display signal representing the non-visual image as the Ir display signal. The timing information may be output to the conversion unit 52.

  FIG. 16 is an explanatory diagram relating to imaging of the display unit 60 by the electronic device 5. Specifically, as illustrated in FIG. 15, FIG. 16 illustrates a display signal that represents a non-viewing image by using a display signal that represents a viewing image and a display signal that represents a non-viewing image as RGB display signals. It is explanatory drawing regarding the imaging of the display part 60 by the electronic device 5 at the time of producing | generating the display signal which makes Ir a display signal.

The imaging unit 110 of the electronic device 5 is displaying an image (a weather forecast image that is a visual image and a two-dimensional barcode that is a non-visual image) based on the display signal as illustrated in FIG. When the display unit 60 of the display device 4 is continuously shot, four captured images as shown in FIG. 16B or FIG. 16C are output to the display / operation receiving unit 100. That is, from the display timing of the weather forecast image and the two-dimensional barcode on the display unit 60 and the exposure timing of the imaging unit 110, for example, in continuous shooting T, as shown in FIG. A dimensional barcode is captured in the _first captured image T ₁ , the second captured image T ₂ , and the fourth captured image T ₄ , and the two-dimensional barcode is captured in the _third captured image T ₃ . Imaged. In the continuous shooting U, as shown in FIG. 16C, a two-dimensional barcode is captured in the _first captured image U ₁ and the second captured image U ₂ , and the weather forecast image and the second captured image U ₂ are captured. The dimensional barcode is captured in the _third captured image U ₃ and the fourth captured image U ₄ .

That is, when a display signal is generated in which a display signal representing a visual image and a display signal representing a non-visual image are RGB display signals, and a display signal representing a non-visual image is an Ir display signal Even so, by continuously shooting the display unit 60 using the electronic device 5, it is possible to recognize a non-viewing image that is not visually recognized. More specifically, if the display timing of the viewing image and the non-viewing image on the display unit 60 and the exposure timing of the imaging unit 110 are appropriately set, at least of the plurality of continuously captured images. Since one image is a captured image obtained by capturing only the non-visual image (the captured image T ₃ , the captured image U ₁ , and the captured image U ₂ described above), the non-visual image is reliably (that is, the visual image and (Without superimposition). That is, the electronic device 5 can obtain connection information to the display device 4.

  The process flow of the image display system 2 is basically the same as the process flow of the image display system 1 of the first embodiment described with reference to FIGS. That is, the display device 3 according to the first embodiment displays a non-visual image during a time (second display period) that does not have a length that allows human vision to respond, whereas the display device 4 according to the second embodiment Although the operation in the display device is different, such as displaying an image for non-viewing using a light emitting unit (second light emitting unit) that emits invisible light, the devices between the devices as shown in FIGS. The process flow between the electronic devices 5 is the same as that of the image display system 1.

  As described above, according to the second embodiment, the same effects as those of the first embodiment can be obtained.

  In the first embodiment, as shown in FIG. 8A, the display device 3 displays a visual image and a non-visual image (in the second embodiment, the display device 4). The same applies to the case where the image for visual recognition and the image for non-visual recognition are displayed), and the fact that the image for non-visual recognition is also displayed in a partial area of the image for visual recognition may be displayed. Accordingly, it is possible to confirm that the non-viewing image is displayed together with the viewing image before the electronic device 5 actually captures the image.

  In the first embodiment, as shown in FIG. 1A, the display device 3 and the server 8 have been described as separate bodies. However, the display device 3 and the server 8 are configured integrally (as one system). (It is also possible to include a configuration of installing in the same place). The same applies to the display device 4 and the server 8 in the second embodiment.

In the first embodiment, the display device 3 connected to the electronic device 5 has been described as receiving drawing information from the electronic device 5 as shown in FIG. The information received by is not limited to drawing information. The same applies to the display device 4 of the second embodiment.
Similarly, in the first embodiment, the electronic device 5 connected to the display device 3 has been described as transmitting drawing information to the display device 3 as shown in FIG. The information transmitted by 5 is not limited to drawing information. The electronic device 5 does not need to shift to the drawing mode when the drawing information is not transmitted. The same applies to the electronic device 5 connected to the display device 4 of the second embodiment.

(Application 1)
After the electronic device 5 is connected to the display device 3 (the same applies to the display device 4, the same applies hereinafter), an advertisement (moving image (CM), still image, character information) is displayed as a visual image, and the display device is displayed as a non-visual image. A connection image indicating connection information to a connection destination other than 3 is transmitted to the display device 3 directly or via a server (may be a server different from the server 8). That is, if attention is paid to the non-viewing image, a connection image (non-viewing image) indicating connection information to the own device (display device) 3 received from the server 8 is first displayed on the display device 3. When the connection to the own device 3 by the device 5 is started, a connection image (non-viewing image) indicating connection information to a connection destination other than the own device 3 is displayed. In other words, when the display device 3 is not connected to the electronic device 5, the display image for connecting to the own device 3 is displayed in a non-visible manner, and when the display device 3 is connected to the electronic device 5, the display device 3 is connected to a device other than the own device 3. The display is switched so that the connection image for non-visual display is displayed.

  Further, when the display device 3 is connected to someone's electronic device 5, the connection image for connecting to the server 8 may be displayed in a non-visual manner as a connection image for connection to a device other than the own device 3. A connection image for connecting to a connection destination (for example, a website) designated by someone may be displayed in a non-visual manner.

For example, it can be used as follows. When the display device 3 (for example, a large outdoor screen) is not connected to the electronic device 5, the display device 3 displays the connection image for connection to the device 3 in a non-visual manner. When the salesman A of N company photographs the display device 3 with the electronic device 5 (for example, a smartphone; the same applies hereinafter), the electronic device 5 of the A connects to the display device 3.
Subsequently, the electronic device 5 of A responds to the operation of A (or automatically on condition that it is connected to the display device 3), and the advertisement of the product (or service, etc.) of the N company as a visual image. And a connection image for connecting to a web page (site) on which information about the product is posted (held, the same applies hereinafter) as a non-viewing image, a server that holds information about the product (for example, a server of N company) ) To the display device 3.
That is, in the above case, the connection destination other than the display device 3 is a server of an organization (N company, agency of N company, etc.) that promotes (advertises) the display device 3. Moreover, the server of the said group distinguishes the image for visual recognition (advertisement) and the image for non-visual recognition (connection image), and transmits to the display apparatus 3. The product information includes specifications, features, campaign information, and the like.

  Subsequently, when the user B who has seen the advertisement of the product of the company N displayed on the display device 3 captures the advertisement with the electronic device 5, the electronic device 5 of the B displays a web page on which information about the product is posted. A connection image for connection is acquired, connected to the web page, and information related to the product is received from the web page and displayed.

  The owner (company) of the display device 3 may charge N companies according to the usage time of the display device 3. The owner of the display device 3 receives the identification information (ID, telephone number, etc.) of the own device (electronic device) 5 transmitted from the electronic device 5 of the A so that the salesman A ( N companies) may be specified. Further, the owner of the display device 3, for example, determines the time from when the display device 3 transmits a connection response (see FIG. 7) to when the disconnection response (see FIG. 7) is transmitted to the electronic device 5 of A. It is good also as the utilization time of the display apparatus 3 by the salesman A (N company).

  The display device 3 displays advertisements for a plurality of products (for example, product images) for visual recognition, and displays each connection image for connecting to each web page on which information about each product is displayed. May be non-visually displayed. When the display device 3 visually displays advertisements of a plurality of products and non-visually displays the respective connection images, when the user finds an interesting advertisement among the advertisements of the plurality of products being displayed, If the advertisement is taken with the camera of the electronic device 5, the electronic device 5 acquires a connection image that is not visually recognized in the display area of the advertisement. You can see information.

  Further, for the purpose of promoting other products (mainly other products with the same advertiser), the display device 3 displays a connection image for connecting to a web page on which information related to the product of the advertisement is displayed invisible. Instead of this, a connection image for connecting to a web page on which information related to a product different from the product of the advertisement may be displayed in a non-visual manner.

  Further, the connection destination other than the display device 3 is not limited to a web page that advertises a product. For example, it may be a web page for selling a product (including a web page for advertising and selling). For example, when the online sales company uses the display device 3, the product image or CM of the mail-order product may be visually displayed on the display device 3, and the connection image for connecting to the purchase screen may be displayed invisible. If the user takes a product image (CM) to be purchased with the camera of the electronic device 5, a purchase screen for the product to be purchased is displayed on the electronic device 5.

  The products advertised on the display device 3 are not particularly limited, and are widely applied, for example, cameras, cars, clothes, food, contents, services (travel agencies, gyms), and the like. Further, the display device 3 may advertise a company, a school, a hospital, an organization, a sightseeing spot, a shopping street, and the like (hereinafter the same).

For example, an advertisement (for example, a demo screen) of game software may be displayed on the display device 3 and a connection image for connecting to a download site for the game software may be displayed in a non-visible manner. If the user photographs an advertisement of desired game software with the camera of the electronic device 5, the electronic device 5 connects to a download site for the game software. In addition, you may charge with respect to those who downloaded game software from the download site.
The advertisement of the advertiser is displayed on a part of the display device 3 (for example, 1/5 from the bottom of the screen), and the portion where no advertisement is displayed is used by the user as a freely usable display device. You may make it make it. The method for using the display device 3 by the user may be the method described above. If the advertiser pays the usage fee for the display device 3, the user can use the display device 3 for free.

  Similarly, the promotion video of the music may be displayed on the display device 3 and the connection image for connecting the incoming melody of the music to the download site may be displayed invisible. If the user shoots a promotional video of a song with the camera of the electronic device 5, the electronic device 5 connects to a download melody download site for the song. In addition, you may charge with respect to the person who downloaded the ringtone from the download site. In addition to music, a preview and a sample video may be displayed on the display device 3 and taken to be able to download movies, dramas, and anime.

  Note that the display device 3 does not always exist at a predetermined position, and may be mounted on a vehicle (for example, an advertisement truck) and moved.

  In the first embodiment, the display device 3 has been described as being connected to the electronic device 5, but may not be connected to the electronic device 5. Specifically, the display device 3 receives the connection image for connecting to the own device 3 from the server 8 and displays it non-visually, but receives the connection image for connecting to a device other than the own device 3 from the server 8. May be displayed non-visually. The same applies to the display device 4 of the second embodiment.

(Application example 2)
Application example 1 is an aspect in which someone's electronic device 5 is connected to the display device 3, and an advertisement is visually displayed on the display device 3 and a connection image is non-visually displayed by the control of the electronic device 5. In Application Example 2, the advertisement is visually displayed on the display device 3 and the connection image is not visually displayed without using the electronic device 5. In other words, in the application example 1, the electronic device 5 is interposed until the display device 3 displays the advertisement. However, in the application example 2, the electronic device 5 is displayed until the display device 3 displays the advertisement. No intervention. That is, the connection destination by the connection image is only the server of the organization that performs the advertisement (advertisement) by the display device 3.

In the case of the application example 2, the company (person) who desires the advertisement (advertisement) does not need to go to a place where the display device 3 (for example, an outdoor large screen) is located, and is away from the place where the display device 3 is located. What is necessary is just to apply for the use of the display device 3 to the owner of the display device 3 from the Internet (for example, the workplace). A company that wishes to advertise, after the owner's permission, transmits information (an advertisement that is a visual image, a connection image that is a non-visual image) that the electronic device 5 connected to the display device 3 in Application Example 1 transmits to the display device 3. ) To the owner. Subsequently, the owner transmits information received from the company that wishes to advertise to the display device 3 via the server 8. As described above, the display device 3 visually displays the advertisement without connecting to the electronic device 5 on the own device 3 and non-visually displays a connection image for connecting to a device other than the own device 3. The movement after the display device 3 visually displays the advertisement and non-visually displays a connection image for connection to a device other than the own device 3 is the same as in the first application example.
For example, a company wishing to advertise obtains information (ID, password, etc.) for accessing the server 8 from the owner when the owner permits, and displays the advertisement and the connection image on the display device 3 itself. You may send it.

  In addition, you may make it the advertisement content (advertiser, goods) by the display apparatus 3 change for every time. For example, like a TV commercial frame, a plurality of advertisements may be set in each advertising frame, and the advertisement set in each advertising frame in each advertising frame may be displayed on the display device 3 in order.

  Also, a plurality of display devices 3 may be installed side by side on the wall of a station premises or a downtown area building. When a plurality of display devices 3 are installed side by side, the content of advertisements by the respective display devices 3 may be different.

  According to the application examples 1 and 2, it is possible to perform a time sale limited to the installation location of the display device 3 and issue a discount coupon limited to the installation location (for example, limited to a certain shopping street). For example, the display device 3 is installed at an entrance, an exit, or the like of a shopping street, displays an image of a discount coupon target product visually, and displays a connection image for connecting to a discount coupon issuing server in a non-visually displayed manner. The consumer can obtain a discount coupon image of the product from the discount coupon issue server by taking a product image with the camera of the electronic device 5.

(Application 3)
Although the application examples 1 and 2 were the aspects which utilize the display apparatus 3 for marketing including sales or an advertisement, in the application example 3, the display apparatus 3 is utilized for provision of map information. For example, in an exhibition held at a large venue such as Makuhari Messe, the display device 3 is used to teach visitors the location of the exhibitor (company) exhibition booth.

  For example, the display device 3 installed in the exhibition hall visually displays each exhibitor's logo (or each exhibitor's logo + information indicating the approximate location of each exhibitor's exhibition booth (for example, an arrow)). At the same time, a connection image for connecting to a web page on which map information for guiding from the installation position of the display device 3 to the exhibitor's booth is displayed in a non-visual manner. If a visitor photographs the exhibitor's logo displayed on the display device 3 with the camera of the electronic device 5, the electronic device 5 displays map information for guiding the exhibitor to the exhibition booth. The above guidance (route guidance to the exhibition booth) is possible because the installation position of the display device 3 is fixed. The display device 3 may be installed at a plurality of different locations in the exhibition hall.

  Similarly, the display device 3 may be used for guidance on underground malls, department stores, sightseeing spots, and the like. Note that the above-described guidance by the display device 3 is particularly useful in places where GPS radio waves cannot be received (or places where it is difficult to receive) such as in underground shopping centers and department stores.

(Application 4)
Moreover, you may utilize the display apparatus 3 as a communication tool with others. For example, the display device 3 is used as a place for announcing personal hobbies. The display device 3 non-visually displays a connection image for connecting to the own device 3. Note that the display device 3 may visually display any image (for example, information explaining how to connect to the own device 3) together with a connection image for connecting to the own device 3.

  When the individual C photographs the display device 3 with the electronic device 5, the C electronic device 5 is connected to the display device 3. Subsequently, in response to the operation of C, the electronic device 5 of C captures (or produces) content (for example, a still image or a moving image) captured by C and a connection image of C's mail address (based on C's mail address). The generated two-dimensional barcode) is transmitted to the display device 3. The display device 3 visually displays the C content and non-visually displays the connection image of the C mail address. When the user D who has viewed the C content displayed on the display device 3 captures the content with the electronic device 5, the D electronic device 5 displays a mail transmission screen to C. D sends a comment on C's content by e-mail.

  Also, the C electronic device 5 may transmit a connection image for connecting to a web page of an electronic bulletin board for posting a comment for C to the display device 3 instead of the connection image of the C mail address. . In this case, the electronic device 5 of D displays an electronic bulletin board for posting a comment on C instead of a mail transmission screen to C.

A connection image for connecting to a device other than the display device 3 described in each application example is generated in advance by converting the original information (for example, the URL of the connection destination web page) into a two-dimensional barcode, You may remember it. In a mode in which the display device 3 receives a connection image for connecting to a device other than the own device 3 from the outside (the server 8, the electronic device 5, etc.) and performs non-visual display, the connection image may be stored outside. The same applies to the connection image for connecting to the own device 3.
In each application example, when an image or the like is transmitted from the electronic device 5 to the display device 3 (display device 4), the transmission may be executed by a physical action as illustrated in FIG. 9C.
