Abstract
A method and apparatus for producing a desired image from an original image on image capturing and processing machines, including copiers, scanners and cameras, comprises designating the part of the image desired with at least one small and uniquely designed indicia element, such as a marked lightly adhesive tab or a marked tile, by placing it on the original image and digitally identifying and processing it according to the design and location of the element. It is shown how such uniquely designed indicia can be used to crop pictures and text from documents including word-to-word cropping, and/or to specify characteristics of the desired image such as resolution, and to determine the rotation or location of the desired images to be produced.
Claims22
The method for deriving an image from an image bearing document comprising the steps of:
- placing relatively small machine identifiable encoded indicia on the document in at least one location;
- recording the document image;
- identifying the indicia, and
- deriving the desired image using the identifiable indicia.
A method for identifying encoding on indicia-bearing elements containing instructions for excerpting portions of a document as it is being scanned, comprising the steps of:
- normalizing the original image including an indicia-bearing element thereon;
- obtaining correlation values between the indicia image and the normalized image;
- identifying the indicia in accordance with the correlation values, and
- identifying the instructions associated with the indicia.
A system for deriving a selected image from an image-bearing basic document, comprising:
- at least one indicia member placed on the document and bearing instructions for production of the image to be derived;
- an image reproduction machine for scanning the image, including the at least one indicia member, on the document;
- a memory apparatus responsive to the scanner for retaining data as to the image on the document;
- and
- a data processor responsive to signals representing the recorded image and the at least one indicia member for deriving the selected image from the document.
A system for producing an extracted image of a portion of a document in accordance with instructions contained in indicia selectively placed on the document, comprising:
- a scanning system for providing a digital record of the document, including the indicia;
- a data processing system receiving the digital record and identifying the instructions, the processing system including programming means for extracting that part of the image defined by the instructions, and
- an output device responsive to the data processing system for presenting the extracted image.
