Abstract
The present invention relates to utilization of metadata associated with a printed image. Portions of images and metadata are stored, each of the metadata being associated with a portion of the images. Imaging means are used to read a portion of the printed image. Correspondence between the read portion and the stored portions is determined. Metadata associated with a stored portion is retrieved in response to the determined correspondence between the read portion and the stored portion in question exceeding a predetermined threshold value. Further, the retrieved metadata or additional data indicated by it is retrieved.
