Method and apparatus for assembling sets of documents

A brightness pattern of a document (71, 101) is stored in a memory. At least a part (73, 102, 105) of another document (71, 101) is optically scanned. The scanned brightness pattern is compared with the stored brightness pattern. When more than a specified minimum extent of agreement between the sca...

More Information
Summary:A brightness pattern of a document (71, 101) is stored in a memory. At least a part (73, 102, 105) of another document (71, 101) is optically scanned. The scanned brightness pattern is compared with the stored brightness pattern. When more than a specified minimum extent of agreement between the scanned and the stored brightness patterns is found, a signal is generated. The composition of the set is carried out in accordance with that signal. Because scanned brightness patterns are compared with a brightness pattern of a document, a random brightness pattern present on a document can be used for controlling the composition of the set. Further, an apparatus for practicing the method according to the invention is disclosed.
