Abstract:
The present invention provides a system and method for scanning selected portions of a document. Briefly described, in architecture, one embodiment projects a beam of light onto a document portion, detects reflected light from the document portion with an image capture device, and determines a location of the document portion on the document based upon information received from the image capture device.
Abstract:
A document reading apparatus comprising a document table, a reading section disposed above the document table for reading a document placed on the document table. The reading section includes a sensor for detecting variations of brightness within a selected reading area of the document which is designated by light beams prior to a reading operation. This apparatus further comprises a display device for displaying the image of the selected reading area.
Abstract:
A combined scanning and staring (SCARING) focal plane array (FPA) imaging system having a plurality of modes of operation is provided. In one example, the SCARING FPA system includes a photodetector array with a plurality of photodetectors arranged in a plurality of photodetector rows, a readout integrated circuit (ROIC) coupled to the photodetector array, and a processor coupled to the ROIC. The processor coupled to the ROIC is configured to dynamically configure the SCARING FPA between a scanning mode of operation and a staring mode of operation.
Abstract:
An electronic device includes a camera that is configured to generate a visual data signal that corresponds to dynamically captured graphic content that includes an image and a pointer that is operable to communicate a selection characteristic of the image. A signal processor receives the visual data signal and is operable to identify a portion of the image in the dynamically captured graphic content responsive to the selection characteristic communicated by the pointer.
Abstract:
Apparatus for imaging an object (24), consisting of a projector (20), which is adapted to project and focus a marker pattern (22) onto the object, and a hand-held camera (26), which is adapted to capture an image of a region (34) defined by the marker pattern when the marker pattern is focussed onto the object.
Abstract:
The present invention relates to a system for de-warping images of a developable surface, including developable curled surfaces, and in particular of images of curled documents (30). The system (1) includes a processor (25) linked to an image capture means (2) which: captures an image of the surface (30), said image having a warp corresponding to the non-planar surface; generates from the image a first set of points representing the three-dimensional profile of the non-planar surface relative (30) to a planar reference surface (12); fits to the first set of points a second set of points representative of a developable mesh; and uses the second set of points to texture-map the image (12) in order to de-warp the image.
Abstract:
A device for recording information has a sensor (8) for recording a primary image of the information, a display (25) for showing a secondary image which constitutes at least part of the primary image, and control means (20, 27), with the aid of which a user can define on which sub-image of the primary image an operation is to be performed. Methods of recording information are also disclosed.
Abstract:
An electronic device includes a projection unit and a detection unit. The projection unit is configured to project light in a projection region on a projection surface. The detection unit is disposed away from the projection unit. The detection unit includes a photodetector and a notification light emitter. The photodetector is configured to detect reflected light of the light from the projection unit within a detection region. The notification light emitter is configured to emit to the projection surface notification light for setting a position of the projection region within the detection region of the photodetector.
