Abstract
A system and method for automatic descreening of a digital image is disclosed. The method comprises automatically detecting, prior to a final scan of the document, the presence of a predefined visual artifact in a sample region of an image of the document being scanned; performing the final scan of the document to obtain the digital image; and automatically descreening the digital image to obtain a final digital image of the document in response to the automatic detection of the predefined visual artifact.
Claims36
A method for automatically improving a digital image of a document, comprising:
- automatically detecting, prior to a final scan of said document, the presence of a predefined visual artifact in a sample region of an image of said document being scanned;
- performing said final scan of said document to obtain said digital image;
- and
- automatically descreening said digital image to obtain a final digital image of said document in response to said automatic detection of said predefined visual artifact.
A method for automatically improving a digital image of a document, comprising:
- determining at least one non-textual portion of an image of said document;
- automatically detecting a predefined visual artifact in said at least one non-textual portion prior to a final scan;
- performing said final scan of said document to obtain said digital image;
- and
- automatically descreening said digital image to obtain a final digital image of said document in response to detecting said predefined visual artifact in said at least one non-textual portion.
A system for automatically improving a digital image of a document, comprising:
- means for automatically detecting, prior to a final scan of said document, the presence of a predefined visual artifact in a sample region of an image of said document being scanned;
- means for performing said final scan of said document to obtain said digital image;
- and
- means for automatically descreening said digital image to obtain a final digital image of said document in response to said automatic detection of said predefined visual artifact.
A method for automatically improving a digital image of a document, comprising:
- automatically detecting, prior to a final scan of said document, the presence of halftone in at least a portion of said document being scanned;
- performing said final scan of said document to obtain said digital image;
- and
- automatically descreening said digital image to obtain a final digital image of said document in response to said automatic detection of halftone.
A system for automatically improving a digital image of a document, comprising:
- an image capture device;
- and
- application logic operatively associated with said image capture device and operable to:
- automatically detect, prior to a final scan of said document, the presence of a predefined visual artifact in a sample region of an image of said document being scanned;
- perform said final scan of said document to obtain said digital image;
- and
- automatically descreen said digital image to obtain a final digital image of said document in response to said automatic detection of said predefined visual artifact.
