The imaging control unit 461 causes the display unit 406 to display an image of image data output by the camera 402 by imaging the subject, and outputs an imaging signal indicating that the air tag information acquisition unit 463 has captured the image. The imaging control unit 461 starts the camera 402 and continuously outputs the imaging signal to the air tag information acquisition unit 463 while displaying the image of the image data output by the camera 402 on the display unit 406.

  In addition, the imaging control unit 461 outputs an error signal to the partial information acquisition unit 467 when the camera 402 is in a state where it does not output image data due to a failure or the like.

  The air tag information acquisition unit 463 acquires air tag information from the air tag server 600. Specifically, when an imaging signal is input from the imaging control unit 461, the air tag information acquisition unit 463 controls the position detection unit 409, causes the position detection unit 409 to measure the current position, and outputs the position detection unit 409. The position information indicating the current position is acquired. The air tag information acquisition unit 463 transmits a transmission request including the acquired position information to the air tag server 600 via the wireless LAN I / F 408. The IP address of the air tag server 600 may be stored in advance in the flash memory 403 of the portable information device 400. As described above, the air tag server 600 that receives the transmission request returns one or more pieces of air tag information or an error signal. Here, the air tag information shown in FIG. 22 is returned.

  When the wireless LAN I / F 408 receives one or more air tag information or error signals from the air tag server 600, the air tag information acquisition unit 463 acquires one or more air tag information or error signals.

  In addition, when an imaging signal is input from the imaging control unit 461, the air tag information acquisition unit 463 controls the azimuth detection unit 410 to cause the azimuth detection unit 410 to detect the imaging direction of the camera 402, and the azimuth detection unit 410 outputs Get the direction to do.
