I think this is a problem with Street View application, but there is a problem when uploading files directly from Google Photo / Drive from iPhone.
Problem summary:
In the Street View application, if “Save album to smartphone” is set, if you connect the camera from the application and shoot, the file of the camera roll becomes output.jpg.
Reproduction procedure:
Advance preparation
Launch the Street View application and select [Settings] > [Save album on your phone] turn on
Turn on the power of THETA SC / Connect to iPhone via Wi-Fi
Launch the Street View application and connect with THETA
One or more 360 degree images
Open the GooglePhoto application
Open the captured 360-degree image saved in the camera roll
Tap [Info] by pressing […] on the upper right
Confirm that the file name is output.jpg.
Open the GoogleDrive application
Press (+) and tap “Upload”
Tap “Photos and videos”
Tap “360 ° Photo”
Upload by selecting the 360-degree image saved in the camera roll
Confirm that all file names are output.jpg.
(When there are two or more, multiple will be synchronized to GoogleDrive with output.jpg)
In the image saved to the camera roll of iPhone with "UIImage → UIImageWriteToSavedPhotosAlbum() ", the name is given based on the DCF (IMG_XXXX), so I think there is a problem in processing in the application.
