And the image which image | photographed the search subject and the map information which shows the position of the portable radio | wireless communication apparatus 20c of the search subject 2c are controlled so that it may be displayed on the monitor 54 of the search terminal 50a.

  Specifically, the server 60 instructs the camera 40c to transmit an image to the search terminal 50a, and an image of the search target person 2c is transmitted from the camera 40c to the search terminal 50a and the search target person 2c. Map information indicating the position of the portable wireless communication device 20c is transmitted from the server 60 to the search terminal 50a.

  The search terminal 50a receives the image of the search target person 2c and the map information indicating the position of the mobile wireless communication device 20c, and displays them on the monitor 54 (S154 in FIG. 6).

  In the second embodiment, the search terminal 50a acquires member information from the server 60 and displays a member list.

  For example, as shown in FIG. 8 (a), four people ("A" 2a, "B" 2b, "C" 2c, and "D" 2d) made up of friends have received admission to the theme park at the same time. To do. Then, a unique ID is assigned to each visitor 2a, 2b, 2c, and 2d, and the IDs of four people are managed in association with each other.

  Note that the number of digits of the ID of the visitor may actually be set appropriately according to the number of people accommodated in the theme park. For example, the personal ID may be 12 digits and the group ID may be 4 digits. However, for the sake of convenience of explanation, a case where the visitor ID is composed of a 3-digit personal ID and a 1-digit group ID will be described below as an example. To do.

  In such a case, as shown in FIG. 8B, the personal information management unit 62 of the server 60 includes the names “A”, “B”, “C”, and the names of the visitors 2a, 2b, 2c, and 2d. “D” and the face image are stored in association with IDs (“1115”, “1125”, “1135”, and “1145”) for each visitor. Here, the personal IDs are “111”, “112”, “113”, and “114”, and the group ID is “5”.

  FIG. 9 shows the flow of processing in the search terminal 50a, and FIG. 10 shows the flow of processing in the server 60.

This personal information request is given the search requester 2a ID ("1115"). When the server 60 receives the personal information request of all the members with the search requester 2a ID (S262 in FIG. 10), the server 60 is the same as the search requester 2a based on the group ID (“5”) of the search requester 2a. The IDs, names and face images of all members belonging to the group are searched (S264) and transmitted to the search terminal 50a (S266). When the search terminal 50a receives the information of all members from the server 60 (S216 in FIG. 9), as shown in FIG. 8C, the monitor 54 of the search terminal 50a has all members 2b except the search requester 2a, The names 2c and 2d ("B", "C", and "D") and face images are displayed in a list, and "Who is this?" Is displayed (S218). Therefore, the search requester 2a selects a search target person with the touch panel 56 of the search terminal 50a while viewing the names and face images of all the displayed members (S220). For example, “C” is selected as a search target person from the list.

  On the other hand, it is also possible to designate a visitor who belongs to a group different from the search client 2a as a search target person. In this case, for example, information on the search target person is acquired from the server 60 using the name of the search target person as a search key. Specifically, when the search requester 2a inputs the name “X” of the search target person on the touch panel 56 of the search terminal 50a while the search request screen is displayed (S234), the search terminal 50a is “X”. The personal information is requested from the server 60 (S236). This personal information request is given the name “X” of the person to be searched. Upon receiving the personal information request for “X” (S262 in FIG. 10), the server 60 searches for the ID and face image of “X” based on the name “X” of the search subject 2c (S264). It transmits to the search terminal 50a (S266). When the search terminal 50a receives the search subject's ID and face image from the server 60 (S236 in FIG. 9), the face image is displayed on the monitor 54 of the search terminal 50a along with the name “X” of the search subject, Asks "Is this person?" (S238). Therefore, the search requester 2a confirms the displayed face image and presses the “confirm” button on the touch panel 56, thereby specifying the search target person (S240).

  When the search target person 2c is specified, the search terminal 50a transmits a search request to the server 60 (S252). Here, the ID of the search target person 2c is given to the search request.

  In FIG. 10, the server 60 uses the wireless reader 30 to read the ID read from each portable wireless communication device 20 and the distance (or direction) to the portable wireless communication device 20 detected by the wireless reader 30. Received from the reader 30 (S268). On the other hand, the server 60 receives the ID “1135” of the search target person 2c from the search terminal 50a (S270). Then, the server 60 sets the position in the theme park of the portable wireless communication device 20c that has transmitted the ID that matches the ID of the search target person 2c to the distance (or direction) from the wireless reading device 30 to the portable wireless communication device 20c. Based on the calculation (S272).

  Next, the server 60 identifies the camera 40c that captures the position of the portable wireless communication device 20c of the search target person 2c (S274), and the camera so as to capture the position of the portable wireless communication device 20c as the center of the image. 40c is controlled (S276).
