    摘要： Apparatus is disclosed having document recognition capability for determining the size and location of an original document on a scanner platen before the document is scanned for image capture, and which effects both document recognition and image capture within a single scan cycle. A platen is optically scanned in forward and reverse intrack directions, and an electrical information signal characteristic of the optical densities scanned is created. Document recognition is responsive to the electrical information signal produced during the forward direction scan for detecting the boundaries of an original document on the platen. Image capture is responsive to the electrical information signal produced during the reverse direction scan for producing a record of the image on the original document. Magnification is provided for changing the size of the recorded image from that of the image on the original document in part by adjusting the speed of the reverse intrack scan, and is automatically adjustable in accordance with the size of the recording sheet.

    摘要： A method of printing an image comprising the steps of converting the image into a digital bitmap comprised of an array of pixels wherein each pixel is assigned a digital value representing marking information, identifying a first edge of a first character, identifying a second edge of a second character and, reassigning the digital value(s) pixel(s) adjacent to the first edge and/or the second edge in order for the first edge to appear contiguous with the second edge.

    摘要： The registration and skew information of a document about to be scanned are detected prior to capturing the entire image of the document. Two sensors, a fixed distance apart, are used to detect the document skew. A third sensor is used to detect the edge position of the document. Paper sensors in the Automatic Document Feeder (ADF) are used to determine the document size. The data from the skew sensors are used to calculate the required skew correction angle and direction by which to rotate the image. The document edge position information together with skew information is used to determine the exact location of a corner of the document. This information is used to correct skewed image in real-time, during scanning the document.

    摘要： A method of printing an image utilizing a printer having print nonuniformities, the method comprising the steps of converting the image into a digital bitmap comprised of an array of pixels wherein each pixel is assigned a digital value representing marking information comprises defining each pixel as either a background pixel, interior pixel, or an edge pixel; and, reassigning the digital value of one or more edge pixels or interior pixels to lower values independently in order to reduce toner consumption. The rendering of the present invention occurs post RIP.
