《Check-in processing》
As shown in FIG. 4, it is first determined whether or not the portable terminal device 20 is finished, that is, whether or not a termination operation has been performed by the user (step S11), and if finished (step S11: YES), FIG. The flow shown in FIG.

  If not completed (step S11: NO), the positioning unit 22 measures the current position to generate positioning information (step S12), and the terminal device ID of the portable terminal device 20 stored in the ROM in the control unit 21 At the same time, it is transmitted to the camera management server 10 (step S13).

  Upon receiving the positioning information and the terminal device ID (step S21), the camera management server 10 extracts a POI group within a predetermined range from the current position of the mobile terminal device 20 from the POI information DB 13 based on the received positioning information ( Step S22).

  Next, the camera management server 10 generates camera parameters corresponding to the extracted POI group and suitable for the model of the mobile terminal device 20. That is, the reference camera parameters (FIG. 2A) that do not depend on the model set for photographing the object indicated by each POI of the extracted POI group, and the correction values of the model of the mobile terminal device 20 with respect to the respective reference camera parameters ( 2B) is read from the camera parameter DB 14, and a camera parameter suitable for the model of the portable terminal device 20 is generated by adding the correction value of the model of the portable terminal device 20 to the set value of the reference camera parameter.

  If not completed (step S31: NO), the camera parameter corresponding to the POI selected in the check-in process is read from the storage unit 26 (step S32). The read camera parameters are written and held in the RAM in the control unit 21 as camera parameters for photographing the object indicated by the selected POI. In addition, image data generated by the imaging unit 27 based on the camera parameters is displayed on the display unit 23, and an adjustment member (such as a slide bar) for adjusting brightness, saturation, hue, and the like among the camera parameters. ) Is displayed. When the user operates the adjustment member as necessary, the camera parameters stored in the RAM are corrected (step S33).

  Next, it is determined whether or not the photographing button of the operation unit 24 has been pressed (step S34). If not (step S34: NO), the process returns to step S31. If the button is pressed (step S34: YES), the captured image processing is executed (step S35), and the image data is written and stored in the storage unit 26 (step S36).

  Next, the camera parameters used to generate the stored image data, that is, the camera parameters held in the RAM in the control unit 21 are stored in the storage unit 26 (step S37). Accordingly, when the correction is performed in step S33, the corrected camera parameter is stored, and when the correction is not performed, the original camera parameter is stored again.

  Next, the stored camera parameters are transmitted to the camera management server 10 together with the corresponding POI (step S38), and the camera processing on the portable terminal device 20 side is terminated. At this time, the camera parameters can be transmitted as additional data of the image data.

  The camera management server 10 receives the camera parameters (step S41), and updates and stores the reference camera parameters and correction values stored in the camera parameter DB 14 based on the received camera parameters (steps S42 and S43). .

  That is, the average value of the camera parameters (luminance, saturation, hue, aperture value, etc.) is recalculated and the calculation result is saved. By executing this process, the camera process on the camera management server 10 side ends.
