If the storage medium runs out of space when storing clip-target information as clip data, data having higher deletion-target priority than others is deleted from among a plurality of stored data to have empty spaces on the storage medium, and then the new clip-target information is stored. The deletion-target priority is determined based on attribution of a plurality of stored data. In this manner, new clip-target information is stored without user's operation, after automatically deleting data having higher deletion-target priority than others (the deletion-target priority is determined based on attribution of clip data). Therefore it is avoided that important clip data is automatically deleted without a user being notified.
