Abstract
A method and apparatus for acquiring a corrected digital image of an object includes a digital camera operable to capture a plurality of color component images, an imager body and a support arm. The support arm is coupled to the imager body and adapted to support the digital camera. An image processor is provided to produce corrected color component images and an image combiner is provided to combine the corrected color component images to form the corrected digital image. The camera is moveable to more than one position to enable to formation of three-dimensional images or images with increased depth of focus.
Claims20
An apparatus for acquiring a corrected digital image of an object, the apparatus comprising:
- a digital camera operable to capture a plurality of color component images corresponding to a plurality of color components of light from the object;
- an imager body;
- a support arm coupled to the imager body and adapted to support the digital camera;
- an image processor operable to process the plurality of color component images to produce a plurality of corrected color component images;
- and
- an image combiner operable to combine the plurality of corrected color component images to form the corrected digital image.
A document scanner, comprising:
- an imager body;
- a document tray associated with the imager body and sized and dimensioned to receive a document thereon;
- a digital camera;
- a support arm coupled to the imager body and carrying the digital camera, the support arm configured to move the digital camera between a plurality of positions relative to the document tray, the document within the document tray being completely within a field of view of the digital camera when the support arm is in each of its plurality of positions;
- wherein the digital camera is operable to capture an image of the document when in each position;
- an image processor operable to process the captured images to produce corrected images;
- and
- an image combiner operable to combine the corrected images to form a single corrected image of the document.
