Abstract:
A scanner comprising a platen positioned along a first plane and configured to support an article to be scanned; one or more illuminators positioned below the platen along a second plane parallel to the first plane, and configured to emit light beams; one or more mirrors positioned between the platen and the one or more illuminators, each of the mirrors being configured to direct a light beam having a directional component parallel to the first and second planes emitted by the illuminators onto the article on the platen at the imaging point; one or more sensors configured to detect the light reflecting off the article at the imaging point along a sensor optical path; and a carriage mechanism constructed to affect relative movement parallel to the first and second planes between platen, and the one or more illuminators and the one or more mirrors in a scanning direction.
Abstract:
An fiber optic imaging device utilizing fiber optics for imaging portions of documents of varying shapes and/or sizes. For example, for imaging a book or any document having a centerfold, where the document will not lay flat (non-planar) against the platen of the image forming device. The device may be shaped to fit in the centerfold of an open document between the platen of the copying device and the document. Additionally, the fiber optic imaging device may also allow for performing a geometric translation based upon a portion of the document, for facilitating document reproduction.
Abstract:
A method of optimal focusing for a document scanner is disclosed. The scanner includes an optic module movable in a given scanning direction to perform scanning operation over an area of a document in a scan line by scan line manner by being driven by an optic module moving mechanism under control of a control unit. The control unit includes a best focus value memory for storage of the best focus value for each scan line. The method includes the steps of moving the optic module to one of scan lines of the document and retrieving the best focus value corresponding to the selected scan line. An focus adjusting mechanism is controlled by the control unit to move the optic module in a second direction to adjust the focus position of the optic module in accordance with the best focus value of the scan line. Once the optic module reaches the scan line, the operation of the optic module is temporarily suspended in order to have the vibration of the optic module damped out. Thereafter, a scanning operation is performed over the scan line.
Abstract:
The invention relates to a device and to a method for optically detecting and receiving, in particular for digitising, interconnected sheets (10) along a margin (6), in particular a book (7), comprising a bearing and/or securing device (8) for the sheets (10) and a receiving device (1) which comprises two angular imaging surfaces (2) which have a common vertex edge (3) and which are arranged in relation to each other, in addition to at least one receiving unit (19). The bearing and/or securing device (8) and the receiving device (1) are arranged in a displaceable manner in relation to each other, such that the vertex edge (3) of receiving device (1) and the margin (6) of the sheets (10) can be joined together. The receiving device (1) comprises traction means (15, 16) which are used to catch at least one sheet (10′) when removing the vertex edge (3) of the receiving device (1) from the margin (6) of the sheets (10).
Abstract:
A scanning or copying system can include imaging elements and one or more system processors that are programmed or adapted to perform image processing methods and algorithms on image data, and in some instances, to enhance the image. Image data is acquired using imaging elements. Some imaging elements may have overlapping or rotated fields of view or employ differing resolutions. For each imaging element, its output is recombined together with the output of one or more other imaging elements. To perform the recombination, the system can extract features in an overlapping region and match these features in multiple images. In some instances, the features matched can be edges. Alternatively, the recombination can be performed by positioning each subimage with respect to a larger image through image matching and location techniques. Parameters from the recombined image can be extracted and these parameters can be used to correct for geometrical and spatial distortions and thereby enhance the image.
Abstract:
A document camera is used to show image of an object on a display. In the document camera, a first image data of the object obtained by a video-capturing device is derived into a second image data and a third image data by an image processor in response to a zoom operation, wherein the second image data results in a zoomed image of the object and the third image data results in a scaled image of the object. In response to the zoom operation, there is also a mark frame data generated by a position information controller, which results in a mark frame. The zoomed image, scaled image and mark frame are then synthesized into a combined image by an image synthesizer, and the mark frame superimposes the scaled image to indicate a result of the zoom operation.
Abstract:
The message recording unit and method identify an article or specify a predetermined position in a content recording medium, input related information corresponding to the article or the predetermined position and record as message information the article and the related information or position information indicating the predetermined position and the related information or an access destination of the related information in correspondence to each other into a storage. The message reproducing unit and method identify the article or reference the content recording medium, search the storage for the message information corresponding to the article or the predetermined position, and read and output the detected message information. The message recording/reproducing method includes the message recording method and the message reproducing method.
Abstract:
An original comprises a first page and a second page as disposed face-down on the platen surface of an image-processing device. The platen is scanned to form a platen image. The positions of two diagonally-opposite corners of the original are determined based on a fixed platen reference point. An original image is formed by cropping the platen image based on the positions of the two original corners. The size and position of either one selected page or both pages are determined based on the two original corner positions. When the image of only one selected page is desired, the image of the selected page is formed by cropping the original image based on the size and position of the selected page. When the images of both pages are desired, the images of both pages are formed by cropping the original image based on the sizes and positions of both pages.
Abstract:
An original pressing apparatus applicable to, e.g., an original reading apparatus having: an original pressing plate; a hinge unit having a first end supported rotatably with respect to the original pressing plate and a second end rotatably supported by an external device; and a press-fixing unit adapted to prevent rotation between said hinge unit and said original pressing plate by pressing the original pressing plate and the hinge unit into contact in a rotation axial direction, wherein the press-fixing unit is capable of releasing a press-contact state.
