A cigarette inspection device for inspecting a filter quality through an inspection image of filter end faces in a bundle of cigarettes for accurately detecting, for example, only contaminations. A pattern image is used for detecting a cigarette location on the basis of a preset location of each cigarette in the cigarette bundle and a search area on the inspection image is set. The pattern image is shifted within the search area, thereby obtaining a position at which the pattern image coincides with an image of the filter end face. An image of a filter end face of the cigarette is cut out from the inspection image according to the detected position, and quality (contamination) is inspected. Inspection results obtained with respect to the cigarettes are aggregated, and a judgment is made on the quality (presence or absence of a contamination) of the filter end face. |
