Abstract: A face-up document scanning apparatus stitches views from multiple video cameras together to form a composite image. The document scanning apparatus includes an image acquisition system and a frame merger module. The image acquisition, which is mounted over the surface of a desk on which a hardcopy document is placed, has two video cameras for simultaneously recording two overlapping images of different portions of the hardcopy document. By overlapping a portion of the recorded images, the document scanning apparatus can accommodate hardcopy documents of varying thickness. Once the overlapping images are recorded by the image acquisition system, the frame merger module assembles a composite image by identifying the region of overlap between the overlapping images. The composite image is subsequently transmitted for display on a standalone device or as part of a video conferencing system.

Abstract: A document camera is described for capturing an electronic image of a document, for subsequent optical character recognition. In order to avoid the need for a user to look through a viewfinder of the camera, the camera comprises a projector for projecting an optical field of view indicator on to the document. The user can see the projected indicator on the document page, indicating the effective field of view of the camera. The camera may include auto-focus and zooming mechanisms. In one form, the camera processes a detected image to determine a capture zone corresponding to whole regions of the document falling entirely within the field of view. The projected indicator is controlled to indicate only the capture zone. When the image is to be captured, the camera zooms in to the capture zone to capture the image at maximum resolution.

Abstract: An image scanning apparatus enables to scan an image in a sub scan direction on a scan medium placed on a plane with a one-dimensional image sensor at a fixed position via a reflecting mirror rotatable around a fixed axis without causing a scan defect due to a change in the optical path length. An image light generated from an image on a scan medium is deflected by a reflecting mirror so as to from an image at a position of an image sensor via an image formation optical system. This image sensor reads a scan image as a one-dimensional main scan line and the reflecting mirror is rotated so as to move a scan position in a sub scan direction. The rotation of this reflecting mirror is interlocked with displacement of the image formation optical system in an optical axis direction, thus enabling to prevent an image formation defect due to a change in the optical path length.

Abstract: The present invention relates to a camera (1) that projects a pattern of visible light (28) onto an object such as a document (10) to be photographed to indicate to a photographer the area of the object within view of the camera. The camera comprising image capture means (18), a lens (2) arranged to image the document (10) in an object plane onto the image capture means (18), an image framing projector (2,20,22) operable to project visible optical radiation (24,26) onto the object plane to indicate to a user of the camera (1) the bounds (28) of the document (10) imaged onto the image capture means (18), and a camera attitude sensor system (9,15) for sensing the attitude of the camera (1). The image framing projector (2,20,22) is operable in response to the attitude sensor system (9,15) to project the optical radiation (24,26) onto the object plane only when the attitude sensor system (9,15) senses that the camera (1) is oriented so that the optical radiation (24,26) will be projected downwards.

Abstract: A material exhibiting apparatus displays an image of a material and a character such as an arrow on a display screen in an overlapped state. A location of a display area is set in synchronization with horizontal and vertical synchronizing signals. The set location of the display area is changed by varying a generation timing of either one or both of the horizontal and vertical synchronizing signals. A display location of the character is changed by changing the set location of the display area. Since the display location of the character is quickly changed on the basis of frequencies of the horizontal and vertical synchronizing signals, the movement of the character can continuously be displayed on the display screen.

Abstract: The projector of the present invention provides a means for interactively displaying and annotating a document image at two separate locations. The projector consists of an image plate having an array of picture elements for displaying the image; a projection mechanism for projecting the image displayed by the image plate onto a projection screen; and a digitizer having a coordinate input array which corresponds to the array of picture elements of the image plate, wherein the image displayed by the image plate changes in response to coordinate inputs to the digitizer. A method for interactively annotating an image communicated between a remote and local image includes the procedure of simultaneously transmitting to the remote projector, annotations made to an image in the local projector. Image enhancement means are provided including an overlap-region calibration, a set of cross-polarizers, a high-intensity strobed flash lamp using interlaced scanning, sub-divided picture elements, and automatic gain correction.
