    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 raster output scanner data controller reads pixels of an image from an image memory and outputs serially pixel data streams to a raster output scanner. The data controller includes an image memory storing a plurality of pixel data blocks in a scan line order, an image memory controller coupled to the image memory, a plurality of first-in, first-out memories coupled to the image memory controller for storing pixel data blocks corresponding to a plurality of beams, and an image controller coupled to the plurality of first-in, first-out memories. The pixel data blocks are transferred from the image memory to the plurality of first-in, first-out memories. The image controller reads the pixel data blocks from the plurality of first-in, first-out memories, converts the pixel data blocks read from the plurality of first-in, first-out memories into a plurality of pixel data streams and outputs the plurality of pixel data streams to the raster output scanner.

    摘要： A method and system for performing error diffusion are disclosed. An ordered set of pixels, including a pixel intensity value for each pixel, is received. Each pixel intensity value includes a value within a range from a low value to a high value, inclusive. An initial error value is also received. Based on the pixel intensity values and the initial error value, a pixel value for each pixel and an updated error value are computed substantially simultaneously with each other.

    摘要： In a digital reproduction system incorporating a single pass scanner, accurate image processing results from processing a subset of grayscale image data. More specifically, scanlines that correspond to the leading edge of a document are stored and processed to detect skew and to obtain an appropriate correction. The lead edge correction is then applied to the entire grayscale image. Accordingly, the present systems and methods eliminate skew from grayscale images in real-time. The corrected image is rendered to binary and stored in electronic pre-collation memory and cropping, masking and other image editing operations can be performed on the binary image data before the image is printed.
