Zusammenfassung:A method for determining a media size of a target scanned on the platen of the flatbed scanner using a fiducial placed on a backer of the flatbed scanner at a predetermined location. The fiducial is comprised of a plurality of objects, either placed in a predetermined pattern or randomly within a fiducial frame. A target is placed on the platen of the flatbed scanner and scanned along with the backer. The scanned image data of the target and backer is searched for the fiducial image. When the fiducial image is found, the media is selected to be of a first target type having a first length, and, when the fiducial is not found the target is selected to be of a second target type have a second length longer than the first length.
