Abstract
A system for providing motion picture photographic film with encoded information, such as unique film footage and frame identification, which can be machine read prior to film processing. This system provides machine readable encoded information markings on the raw stock film which may be read in a camera or other photoprocessing device with a reader prior to or concurrent with the film image capture process. The machine readable encoded information markings may be easily converted into a “video image” for display in a real time video from a CCD imager in the film camera or other device. Furthermore this pre-processing machine readable encoded information may be used in conjunction with optical latent image recorded information which becomes machine or human readable after processing as presently provided by film manufacturer's according to industry standards.
