ABSTRACT:
Apparatus for embedding information in a digital image digitized from a developed photographic film in response to a film property and information to be embedded into the digital image includes a scanner for scanning the image on the developed photographic film to produce the digital image. The apparatus stores the film property and has input circuitry for storing information associated with the image and to be embedded in the digital image. The apparatus responds to the stored the film property and the associated information for modifying a predetermined number of pixel values with the associated information in the digital image so that the associated information is embedded in the digital image, wherein the embedded information can subsequently be extracted.
