Abstract: Provision is made in electronic document processing systems for printing unfiltered or filtered machine-readable digital representations of electronic documents, and human-readable renderings of them on the same record medium using the same printing process. The integration of machine-readable digital representations of electronic documents with the human-readable hardcopy renderings of them may be employed, for example, not only to enhance the precision with which the structure and content of such electronic documents can be recovered by scanning such hardcopies into electronic document processing systems, but also as a mechanism for enabling recipients of scanned-in versions of such documents to identify and process annotations that were added to the hardcopies after they were printed and/or for alerting the recipients of the scanned-in documents to alterations that may have been made to the original human-readable content of the hardcopy renderings. In addition to storage of the electronic representation of the document, provision is made for encoding information about the electronic representation of the document itself, such as file name, creation and modification dates, access and security information, printing histories. Provision is also made for encoding information which is computed from the content of the document and other information, for purposes of authentication and verification of document integrity. Provision is also made for the encoding of information which relates to operations which are to be performed depending on handwritten marks made upon a hardcopy rendering of the document; for example, encoding instructions of what action is to be taken when a box on a document is checked. Provision is also made for encoding in the hardcopy another class of information: information about the rendering of the document specific to that hard copy, which can include a numbered copy of that print, the identification of the machine which performed that print, the reproduction characteristics of the printer, the screen frequency and rotation used by the printer in rendering halftones. Provision is also made for encoding information about the digital encoding mechanism itself, such as information given in standard-encoded headers about subsequently compressed or encrypted digital information.

Abstract: An image-sensing apparatus (10) of the type employing resolving and sensing means is provided with sensors (30) of selected size and geometry to allow approximation of desired response. The sensors may be incorporated into compact, self-contained image-resolving and-sensing apparatus having a transparent substrate (12) for resolving an incident image by refraction, diffraction or other suitable mechanism. The sensors may be located directly on a surface (14) of the substrate. Logic and select circuitry (20) may be integrally and simultaneously formed with the sensors. The size and geometry of the sensors may enable approximation to color inhibition and other effects to allow approximation to the spectral response of the human eye.

Abstract: A form (10) including user-modifiable fields (18) and an encoded description (26) of the location, size, type, etc. of the fields allows direct programming of a form interpreter. Other information, including the processing of the form, encoded data, etc., may be included in the encoded information. A system for creating forms carrying an encoded description of selected attributes of the fields includes means for selecting or creating fields and locating the fields on a form while generating, substantially simultaneously, the encoded description of the selected attributes. A form composer then allows merging of the form and its encoded description for printing or electronic transmission. A system for reading such forms includes a scanner, decoding device, and processor. By reading such forms, data may be entered into or recalled from a data-processing system, or a form interpreter may be programmed, locally or remotely, for subsequent handling of forms.
