Next, the operation and use method of the navigation system 1, particularly the operation and use method of the user terminal 4 will be described. Here, FIG. 5 is a flowchart showing an operation flow of the user terminal 4 as an embodiment to which the transmission method of the present invention is applied.
First, when the user performs an operation related to the start of position acquisition on the input unit 44, the input control unit 51 inputs that the position acquisition is started, and the position information acquisition unit 52 acquires the current position by the GPS unit 45 ( Step S1). Then, when the position information transmission unit 54 transmits the information of the current position acquired by the position information acquisition unit 52 to the management server 2 by the wireless control unit 47 (step S2), the map image 100 is transferred from the management server 2 to the user terminal 2. Sent to. The map image receiving unit 58 receives the map image 100 by the wireless control unit 47 (step S3), the display control unit 56 displays the map image 100 on the display unit 46, and the scale detecting unit 57 reduces the scale of the map image 100. Is detected.

  Until the user performs an operation related to the end on the input unit 44 and the input control unit 51 inputs the end (step S4: No), the user performs an operation related to imaging on the input unit 44. When the input control unit 51 inputs that the image is captured (step S5: Yes), the imaging control unit 53 inputs the captured image captured by the drive circuit 42 and the imaging device 43 (step S7) and obtains position information. The unit 52 acquires the current position with the GPS unit 45 (step S8), and the combined unit 55 temporarily stores the captured image input by the imaging control unit 53 in association with the current position obtained by the position information acquisition unit 52 ( Step S9). Here, when the current position is acquired by the position information acquisition unit 52, the synthesis unit 55 generates a layer of the same scale as the map image 100 and draws a mark at a position on the layer corresponding to the acquired current position. In addition, a line from the previously acquired position to the current position is drawn on the layer. Then, the combining unit 55 combines the map image 100 with the layer, and the display control unit 56 displays the map image with the layer combined on the display unit 46 and also displays the captured image on the display unit 46 as necessary.

  On the other hand, when the user performs an operation related to position acquisition on the input unit 44 and the input control unit 51 inputs that the position is acquired (step S5: No, step S6: Yes), the position information acquisition unit 52 Acquires the current position by the GPS unit 45 (step S10), and the synthesis unit 55 temporarily stores the current position acquired by the position information acquisition unit 52. Here, when the current position is acquired by the position information acquisition unit 52, the synthesis unit 55 generates a layer of the same scale as the map image 100 and draws a mark at a position on the layer corresponding to the acquired current position. In addition, a line from the previously acquired position to the current position is drawn on the layer. Then, the combining unit 55 combines the map image 100 with the layer, and the display control unit 56 causes the display unit 46 to display the map image with the layer combined.

The routine of step S4 to step S11 will be described in more detail with reference to the drawings as an example. Here, FIG. 6 is a diagram schematically showing the map image 100, the layer, and the captured image stored in the synthesis unit 55 (mainly the RAM 50b).
When the user travels with the user terminal 4 after receiving the map image 100, an operation related to position acquisition is performed on the input unit 44 (step S6: Yes). As a result, as shown in FIG. 6, the layer 103 is generated by the combining unit 55, and the mark 104 at the current position acquired by the position information acquisition unit 52 is drawn on the layer 103 by the combining unit 55. The line 105 is also drawn on the layer 103 by the synthesis unit 55. The layer 103 is temporarily stored by the synthesis unit 55 (step S11). Note that the combining unit 55 draws the mark 108 associated with the captured image 106 in white, but draws the other marks 102, 104, and 111 in colors other than white. As a result, the mark 108 associated with the captured image 106 is differentiated from the other marks 102 and 104.

  Thereafter, when the user performs an operation related to imaging on the input unit 44 (step S5: Yes), the captured image 106 captured by the imaging device 43 is input by the imaging control unit 53. As before, the layer 107 is generated, the mark 108 at the current position is drawn on the layer 107, and the line 109 from the mark 104 to the mark 108 is drawn on the layer 107. Further, the captured image 106 and the layer 107 are temporarily stored in association with each other by the combining unit 55 (step S9).

  Thereafter, when the user performs an operation related to position acquisition on the input unit 44 (step S6: Yes), the layer 110 is generated, the mark 111 at the current position is drawn on the layer 110, and the marks 108 to 111 are displayed. A line 112 is drawn on the layer 110. The layer 110 is temporarily stored by the synthesis unit 55 (step S11).

  Thereafter, when the user performs an operation related to termination on the input unit 44, the input control unit 51 inputs the termination, and the routine from step S4 to step S11 is terminated.

  After the routine of step S4 to step S11, the synthesizer 55 superimposes the generated layer (for example, layers 103, 107, 110) on the map image 100 and synthesizes the captured image (for example, captured image 106) with the map image 100 and the layer. (Step S12). Here, the combining unit 55 generates a route display program for displaying the combined map image 100, the layer, and the captured image. The route display program includes the map image 100, the layer, and the captured image. Yes. The route display program will be described later.

  Thereafter, when the user performs an operation related to transmission to the transmission destination address on the input unit 44, the input control unit 51 inputs the transmission destination address and the fact of transmission. Then, the mail transmission unit 59 attaches the route display program to the mail, and transmits the mail to the mail server 3 by the wireless control unit 47 (step S13). And the process of the user terminal 4 is complete | finished and the mail server 3 transmits the mail to a transmission destination mail address.

  Here, assuming that the mail transmission destination is a mailbox of another user terminal 4, the operation of another user terminal 4 as an embodiment to which the received image display method of the present invention is applied will be described.

  When the arithmetic processing unit 50 of another user terminal 4 executes the terminal program, the arithmetic processing unit 50 functions as a mailer, and the arithmetic processing unit 50 displays a route by the wireless control unit 47 by the function of the arithmetic processing unit 50 as a mailer. The mail with the program attached is received from the mail box of the mail server 3 (corresponding to a receiving means), and the arithmetic processing unit 50 stores the mail and the route display program in the RAM 50b. When the arithmetic processing unit 50 of another user terminal 4 executes the route display program 50b, the arithmetic processing unit 50 expands the map image 100, the layer, and the captured image in the RAM 50b. The arithmetic processing unit 50 sequentially overlaps the map image 100 to display the layer on the display unit 46 and displays the captured image on the display unit 46 as necessary (corresponding to the route information display unit and the image display unit). .)

  Explaining in detail using FIG. 6, the arithmetic processing unit 50 displays the map image 100 on the display unit 46 (step S <b> 101), and determines whether there is a layer that is not displayed (step S <b> 102). When there is a layer that is not displayed (step S102: Yes), the arithmetic processing unit 50 causes the map image 100 and the layer to be displayed on the display unit 46 by superimposing the layer on the map image 100 (step S103). If there is no layer (step S102: No), the processing of the arithmetic processing unit 50 ends. After displaying the layer on the map image 100, the arithmetic processing unit 50 determines whether or not the captured image is associated with the layer (step S104). If there is a captured image associated with the image (step S104: Yes), the arithmetic processing unit 50 causes the display unit 46 to display a map image when the input unit 44 is operated by the user (step S105). The processing of the arithmetic processing unit 50 returns to step S102. On the other hand, when there is no associated captured image (step S104: No), the processing of the arithmetic processing unit 50 returns to step S102.

  For example, when a route display program including the map image 100, the layers 103, 107, and 110 and the captured image 106 as shown in FIG. 6 is received by another user terminal 4, the display unit 46 of the other user terminal 4 displays FIG. A display as shown in FIG. That is, first, the map image 100 is displayed on the display unit 46 (step S101), and then an image obtained by overlaying the layer 103 on the map image 100 is displayed on the display unit 46 (step S102). Here, the mark 104 drawn on the layer 103 is flushed and displayed. Next, an image obtained by superimposing the layers 103 and 107 on the map image 100 is displayed on the display unit 46 (step S102). Here too, the mark 108 drawn on the layer 107 is flushed and displayed, but the mark 108 associated with the captured image 106 is differentiated from the other marks 102 and 104, so that the arithmetic processing is performed. The unit 50 causes the display unit 46 to distinguish the mark 108 from the other marks 102 and 104 and display them in white. Further, since the captured image 106 is associated with the layer 107, when the user operates the input unit 44, the arithmetic processing unit 50 designates the mark 108 of the layer 107 by a signal input from the input unit 44, and the arithmetic processing unit 50 displays the captured image 106 associated with the layer 107 on the display unit 46 (step S105). Next, in a state where the mark 111 is flushed, an image obtained by superimposing the layers 103, 107, 110 on the map image 100 is displayed on the display unit 46 (step S102), and the processing by the route display program is completed.

  As described above, if the user operates the user terminal 4 while holding the user terminal 4, the layer in which the sequentially acquired current position mark is drawn is combined with the map image 100 and attached to the mail. Can be sent. The other person who has received the mail at another user terminal 4 can grasp the route the user has traveled by looking at the content displayed on the other user terminal 4. Therefore, the user can easily transmit the route taken by the user to another person using the user terminal 4.

  In particular, when a user sequentially captures the current position using the user terminal 4 and captures a landscape or the like, the captured position is also acquired, and the layer on which the position is drawn is combined with the map image 100. Sent by email. Furthermore, a captured image is associated with the position. Therefore, when the other person views the mark position and the captured image on another user terminal 4, the route taken by the user can be more easily grasped.

The present invention is not limited to the above embodiment, and various improvements and design changes may be made without departing from the spirit of the present invention.
For example, the functions of the management server 2 may be distributed to other servers, the map database may be stored in a file server, and the management server 2 may be configured to read the map database in the file server through a LAN connection. In this case, a device combining the management server 2, the LAN and the file server corresponds to a “server”, and a router is provided between the LAN and the network 5, and the management server 2 is connected to the network 5 through the router. It is like that.

  Further, the acquisition of the current position in step S10 is performed every time the user operates the input unit 44, but may be performed every time a predetermined time elapses.

  In the above embodiment, when the combining unit 55 combines the map image 100, the layer, and the captured image in step S12, the route display program is generated, and the map image 100, the layer, and the captured image are included in the route display program. On the other hand, the map image 100, the layer, and the captured image may be transmitted as data attached to an email. In this case, another user terminal 4 stores a route display program in the ROM 41 or the like, and when the arithmetic processing unit 50 of the other user terminal 4 receives the map image 100, the layer, and the captured image, the route display program is stored. When executed, the arithmetic processing unit 50 operates as shown in FIG.

  In the above embodiment, the compositing unit 55 does not directly depict the mark of the current position acquired by the position information acquisition unit 52 in the map image 100 but in a layer. A mark may be drawn directly on 100. In this case, the mail transmission unit 59 transmits the map image 100 and the captured image in which the mark is directly depicted.
