A method and an apparatus inspect whether a surface of an article has a valuable document, in particular whether a piece of mail is provided with a franking mark. A computer-available image of the surface region to be examined is generated. An inspection determines whether the image contains an object image which corresponds to an object image stored in a valuable document data memory. When the image contains a corresponding object image, it is determined that the surface region has a valuable document. When the image does not contain such an object image, then an inspection is carried out to determine if a predefined inspection region has a predefined security feature. When a security feature has been determined, a valuable document is sought in the inspection region using the image. When a valuable document is found in the inspection region, an image of the valuable document is generated and stored. |
