More specifically, when the target shooting condition information is stored in the shooting information database (FIG. 4), the shooting enable condition is satisfied. The processor 22 refers to the “shooting condition” field of the shooting information database and determines whether or not the target shooting condition information is stored.
When the target shooting condition information is stored in the shooting information database, the processor 22 determines that “shooting is possible”.
The processor 22 determines that “imaging is impossible” when the target imaging condition information is not stored in the imaging information database.

The seventh embodiment can be combined with the first to sixth embodiments. That is, the seventh embodiment can be similarly applied when the user U designates the combination of the moving image name and the shooting condition. In this case, the processor 22 determines whether or not shooting is possible, based on whether or not the combination of the target moving image type identification information and the target shooting condition information is stored in the shooting information database.

According to the seventh embodiment, it is determined whether or not the moving image corresponding to the shooting condition can be shot. As a result, even when the user U specifies the shooting condition instead of the moving image type (for example, moving image name), the same effect as that of the above embodiment can be obtained.
