Abstract: This invention is directed toward a system and method for scanning a scene or object such as a whiteboard, paper document or similar item. More specifically, the invention is directed toward a system and method for obtaining a high-resolution image of a whiteboard or other object with a low-resolution camera. The system and method of the invention captures either a set of snapshots with overlap or a continuous video sequence, and then stitches them automatically into a single high-resolution image. The stitched image can finally be exported to other image processing systems and methods for further enhancement.

Abstract: A raster image processing method is adapted for a rasterizing device which converts original image data into raster image data suitable for an image forming device having a plurality of recording heads and performing recording of an image on a recording medium using the plurality of recording heads. The original image data is divided into image data elements for areas of the recording medium for the plurality of recording heads to perform the recording of the image respectively. The divided original image data elements are rasterized into the raster image data suitable for the image forming device.

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: An automatic document feeder (ADF) has a paper path that starts with an input tray, leads to an operational station such as a scanner, and then ends with a substantially vertical output tray. The ADF has a mechanism for picking off an individual media sheet from a stack of sheets in the input tray and propelling the sheet to the operational station where a function is performed on the sheet. Thereafter the ADF propels the sheet partially into the output tray, and momentarily stops or reverses the direction of travel of the media sheet before finally driving the entire sheet into the output tray. This ensures that if the topmost sheet in a stack in the output tray which is being lifted up by the sheet being driven into the output tray, the topmost sheet will be fall back down to a rest position in the output tray and will not spill out of the output tray. The combination ADF and scanner can be operated so that it will automatically detect whether a standard-sized sheet of media is being fed into the scanner in landscape orientation or an over-sized sheet of media is being fed into the scanner in portrait orientation. In the case of the latter, first and second portions of the over-sized sheet are successively registered over the transparent platen of the scanner and scanned. The over-sized sheet is thereafter ejected from the scanner into an output tray. The resulting digital images of the first and second portions of the over-sized sheet are rotated, stitched together by a control circuit using software and/or firmware algorithms and the complete image of the over-sized sheet is stored in a memory, faxed or printed.

Abstract: A composite higher resolution image of an object can be obtained by combining or patching together multiple low-resolution camera images to form a composite image having a higher resolution. Each low-resolution camera image represents a subsection of an object (also referred to as “object subsection”) to be scanned. For example, each subsection may represent a quadrant of a document page. With the use of a periscope, the image visible to the camera can be shifted to capture images of the various object subsections. Mosaicing techniques are used to combine these camera images into a composite image of the object. This approach to scanning improves the resolution of documents scanned while using existing low cost video cameras.
