  FIG. 1 shows a configuration of a display system according to the present invention. A terminal device 2 having an image pickup device such as a camera or a video for taking an image printed on a display medium 1 and an information distribution web server 3 are shown. Are connected through a communication network 4. The database 19 stores information to be provided to the terminal device 2 and is connected to the information distribution web server 3. The connection with the information distribution web server 3 may be a connection through the communication network 4.

  The display medium 1 is a large signboard or sign that can be viewed by many people. As shown in FIG. 2, the display medium 1 is configured by arranging, on the surface of a lenticular image 5, a lenticular lens 6 formed in a sheet shape by arranging a number of elongated convex lenses 6A in the longitudinal direction of the medium. The lenticular image 5 is obtained by cutting two or more images into long and narrow strips, and arranging the cut images alternately in order to form a single image. A lenticular lens 6 is pasted on the image. A display medium 1 is configured. It is also possible to print the lenticular image 5 directly on the back surface of the lenticular lens 6. The sheet made of lenticular lens 6 is made of transparent plastic.

  Specifically, two images of an A image and a B image are formed on the surface of the display medium 1 in this example. Then, when the display medium 1 is created, the A image and the B image are each striped, and the strips are alternately arranged adjacent to each other to form one lenticular image 5. Then, by disposing one convex lens 6A of the lenticular lens 6 on a pair of adjacent strips of the A image and the B image, when the display medium 1 is viewed from the outside through the lenticular lens 6, it corresponds to the viewing angle. Thus, one of the A image and the B image can be visually recognized.

  As the terminal device 2, a built-in or externally connected imaging device such as a camera or video for photographing an A image or a B image according to an angle at which the surface of the display medium 1 is photographed is used. . However, in the display system having the route guidance described below as an embodiment, a portable information device such as a normal mobile phone or a smartphone with a built-in camera or video that can be carried around by a general user, or a portable type device. A personal computer is preferred. Therefore, hereinafter, this route guidance will be described as “portable terminal device” in the description of the embodiment. The display system can be used by installing a dedicated application in advance in the mobile terminal device 2 as described above. The installation can be performed, for example, by accessing a URL for downloading this application.

  FIG. 3 schematically shows an example of use of a display system for road guidance. At the intersection, a person walking from the x direction and b person walking from the y direction are respectively in the p direction. I will explain the case of guiding the route to the ground. In this case, the display medium 1 is provided at the corner of the intersection located in front of each of the a person and the b person.

  In the display medium 1, the A image viewed from the x direction and the B image viewed from the y direction are different from each other, but the contents displayed by the display medium 1 are related to the facility or service at the destination place. It is fixed information that does not need to be rewritten. When the user wants to confirm the route from the intersection to the destination, the user of the mobile terminal device 2 activates the dedicated application by performing key operation or touch operation on the screen, and directs the camera lens toward the display medium 1, so Depending on the position, the a person takes an A image, and the b person takes a B image.

  After shooting, the mobile terminal device 2 performs recognition processing to determine whether the shot image is an A image or a B image. This image is automatically transmitted. Such image recognition is performed by determining whether the reference image registered in the dedicated application is the same as the image captured by the camera.

  The information distribution web server 3 extracts the information distinguished according to whether the image recognized by the mobile terminal device 2 is an A image or a B image from the database 19 and downloads it to the mobile terminal device 2. In the case of a road guidance display system, the database 19 stores information such as directions regarding movement from the position of viewing the display medium 1 to the destination. Therefore, when the information distribution web server 3 identifies the position of the mobile terminal device 2 (that is, the position of the user) from the transmitted image, the information distribution web server 3 extracts the route information corresponding to the position from the database 19, and the mobile terminal device 2 to send.

  In the mobile terminal device 2, the downloaded information is displayed on the display unit 2A, whereby the user is provided with the route information from the information distribution web server 3. Therefore, the a person's mobile terminal device 2 displays information including a mark and a detailed map on the way to the destination, going straight in the p direction across the intersection, and on the b person's mobile terminal device 2 Turn right, proceed in the direction p, and display information along with landmarks and detailed maps along the way to the destination. In addition, by including voice information in the route information downloaded to the portable terminal device 2, voice guidance from the portable terminal device 2 is also possible.

  Therefore, different information is downloaded to each mobile terminal device 2 for two users who have different positions when viewing the display medium 1.

  Thus, since the information displayed on the mobile terminal device 2 is downloaded from the information distribution web server 3, it is possible to easily cope with a change in information. Therefore, even if the destination is changed, it is only necessary to rewrite the route information stored in the database 19 without changing the display of the display medium 1.

  FIG. 4 is a block diagram illustrating a configuration of the mobile terminal device 2. The mobile terminal device 2 includes a central processing unit 10, a memory unit 11 that stores a control program executed by the central processing unit 10 and the dedicated application, a key input unit 13, a camera 14, and a speaker 15.

  The central processing unit 10 displays an image captured by the camera 14 on the display unit 2A. At this time, the central processing unit 10 determines whether the reference image registered in advance and the image captured by the camera 14 are the same. If the image from the camera 14 is an A image or a B image, the central processing unit 10 transmits the A image or the B image to the information distribution web server 3 through the communication means 16.

  FIG. 5 shows a functional configuration of the information distribution web server 3 in a block diagram. The information distribution web server 3 includes an image reception unit 25, an image determination unit 26, an information extraction unit 27, and an information transmission. Means 28.

  In FIG. 5, when an image is sent from the mobile terminal device 2 to the image receiving means 25, the type of the image sent by the image determining means 26 is determined. The image determination unit 26 performs the same operation as the image recognition of the mobile terminal device 2, but the image determination unit 26 of the information distribution web server 3 is formed on another display medium 1 that is not directly related to the present description. A reference image for another image other than the A image and the B image is also registered, and it is determined which matches. In accordance with this, the database 19 also stores route information corresponding to these images.

  When the image determination unit 26 determines that the transmitted image matches any image, the information extraction unit 27 stores the route information related to the image in the information stored in the database 19. The information transmission means 28 downloads the extracted information to the mobile terminal device 2.

  Accordingly, the mobile terminal device 2 displays the downloaded route information on the display unit 2A, and the route information based on the voice information is uttered from the speaker 15 to perform voice guidance.
