Image tags are provided for selective scaling of each area of an image according to the type of content of each area by selective implementation of a window averaging processing technique or an interpolation processing technique. The interpolation processor is implemented for line drawing areas of an image, and the window averaging processor is implemented for contone areas of the image. For anamorphic scaling with image tags, a two-pass system is provided which performs a first-pass reduction in one direction followed by a second-pass enlargement in the remaining direction, wherein the reduction is performed in the manner described for reduction scaling. A one-pass system is also provided which provides a second serially connected interpolator so that the aforementioned reduction can be performed on one dimension in a first step, followed by enlargement in the remaining direction in a following step on the same pass.

摘要： A system and method for reducing an image by receiving a scaling factor which defines a window. Input pixel intensities of the image are summed in real time as they are input and stored until all pixels within the window have been received. The sum is then divided by the number of pixels within the window which produces an average intensity. A pixel having the average intensity is output.

摘要： A scanner enables full productivity and individual image size detection, without user intervention for mixed size originals in both simplex and duplex scanning modes. The scanner provides high-productivity single pass scanning while preserving the image size for each of the document scanned. In addition, the scanner may support duplex scanning by adding a second image sensor, for example, in the document handler. Methods of scanning are also provided.

摘要： A system and method to provide 180-degree rotation of image data at full throughput. The system includes a memory access controller that writes bursts of image data into a rotation buffer. The image data is then read out of the rotation buffer in the reverse order from which it was written to thereby accomplish rotation. By alternating the position in the rotation buffer in which the image data is written such that an image is either written into the buffer from top and read from the bottom or written into the buffer from the bottom and read out from the top, a one page rotation buffer of can be used to concurrently process two pages.

摘要： A method for achieving high resolution printing using low resolution LED bars is performed by arranging the bars at particular angles to the photoreceptor and timing the activation of the pixels within the LED bars according to the movement of the photoreceptor. In addition, the LED bars may be segmented and arranged so that the segments abut one another at different locations. Each of the abutting segments is disposed at a particular angle to the photoreceptor in the process direction. A lens arrangement is used to image the LED bars.

摘要： A control system for a ROS scanner in which the aspect ratio and magnification of an image is controlled by precise, real-time control of the relative velocities of the polygon mirror and the photoreceptor. Values related to monitored measurements of polygon mirror and photoreceptor velocity are mathematically combined with a reference clock value and other factors to yield real-time control signals. The control signals operate the polygon and photoreceptor motors to obtain a desired magnification and aspect ratio of images created on the photoreceptor.

摘要： A system and method are provided for digital correction of a plurality of color channels and color image data. In color reproduction, a color image may be composed of a plurality of superimposed color channels in a color space. In order to assure the proper alignment of color channels and exemplary applications such as color printing, one or more of the plurality of color channels which compose a complete color image may be scaled to an output resolution, and corrected in order to ensure proper alignment and authentic reproduction of a color image. In place of a plurality of independent clocks, one for each channel, a single clock is provided for every channel, and additional unit is supplied to scale each channel according to independent characteristics.
