An approximate circle approximated to the profile of a filter end face in an inspection image obtained by photographing the filter end face of a filter cigarette is obtained, and the center position of the approximate circle is found. An area indicating a string-like flavor containing element embedded in the filter is detected in the inspection image, and the position of gravity center of the area is found. Distance between the gravity center position indicating the flavor containing element and the center position of the approximate circle is determined, and thus, the quality of the flavor containing element embedded in the filter is inspected. |
