  • Publication number: 20190364198
    Abstract: A digital camera includes a detection unit, an operation history storage unit, an analysis unit, a determination unit, and a warning unit. The detection unit detects an imaging operation and a setting operation of a user as user operation information. The setting operation is an operation to set setting information of a first setting item and setting information of a second setting item selectable exclusively with respect to the setting information of the first setting item for setting items relating to imaging conditions. The analysis unit acquires normal operation information based on an imaging operation history and a setting operation history stored in the operation history storage unit. After the normal operation information is acquired, in a case where the user operation information is different from the normal operation information, the determination unit determines that the user is in the confused state. The warning unit issues a warning in a case where determination is made to be the confused state.
