Abstract
A method of identifying a scanned image includes creating an original image with a plurality of halftone resolutions. The original image is then scanned at a scanning resolution to create the scanned image. When the scanning resolution is related to at least one of the plurality of halftone resolutions of the original image, a stamp is generated in the scanned image.
Claims36
A method of identifying a scanned image, the method comprising:
- creating an original image with a plurality of halftone resolutions;
- scanning the original image at a scanning resolution to create the scanned image;
- and
- generating a stamp in the scanned image when the scanning resolution is related to at least one of the plurality of halftone resolutions of the original image.
A system for identifying a scanned image, the system comprising:
- an original image having a plurality of halftone resolutions;
- and
- an optical scanner having a scanning resolution that is related to at least one of the plurality of halftone resolutions of the original image,
- wherein the optical scanner is adapted to scan the original image and generate a stamp in the scanned image when the scanning resolution of the optical scanner is related to the at least one of the plurality of halftone resolutions of the original image.
A method of creating a halftone image, the method comprising:
- producing a first image portion of the halftone image with a first halftone resolution;
- and
- producing at least a second image portion of the halftone image with at least a second halftone resolution, including varying the at least second halftone resolution of the at least second image portion from the first halftone resolution of the first image portion.
A halftone image, comprising:
- a first image portion having a first halftone resolution;
- and
- at least a second image portion having at least a second halftone resolution, wherein the at least second halftone resolution of the at least second image portion varies from the first halftone resolution of the first image portion.
A computer-readable medium having computer executable instructions for performing a method of identifying a scanned image, the method comprising:
- creating an original image with a plurality of halftone resolutions;
- scanning the original image at a scanning resolution to create the scanned image;
- and
- generating a stamp in the scanned image when the scanning resolution is related to at least one of the plurality of halftone resolutions of the original image.
A computer-readable medium having computer executable instructions for performing a method of creating a halftone image, the method comprising:
- producing a first image portion of the halftone image with a first halftone resolution;
- and
- producing at least a second image portion of the halftone image with at least a second halftone resolution, including varying the at least second halftone resolution of the at least second image portion from the first halftone resolution of the first image portion.
