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.

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.

摘要： This invention relates to an imaging device that extends the processing of resources to data having a greater bit-depth. A signal having data at the first bit-depth is received, and at least a portion of the data at the first bit-depth is converted into an estimated value that is at the second bit-depth. A residual that indicates a difference between the data and the estimated value is determined. The estimated value is processed through the resource to form processed data that is at the second bit-depth. The data is then substantially recovered at the first bit-depth from the processed data that is at the second bit-depth and based on the residual.

摘要： An embodiment generally relates to a device for rotating image tiles using line segment read buffers. The device comprises an image memory configured to store an image and a plurality of buffers, wherein the image comprises a plurality of tiles. The plurality of buffers comprises line segment read buffers configured to interface with the image memory to read line segments of the plurality of tiles from the image memory. A rotator logic module is configured to micro-rotate the line segments, aggregate the line segments as rotated tiles, and macro-rotate the rotated tiles to determine an address of the image memory at which to write the rotated tiles. Write buffers are configured to write the rotated tiles to the image memory at the determined address.

摘要： Methods and systems for performing resolution expansion with high quality edge enhancement capability utilizing an edge detector and a color estimator. An edge tag with respect to an input image can be detected via an edge detector and an edge detection approach. A resolution expansion can be separately applied to the edge tag and a binary output generated by other processing functions. Multiple output lines corresponding to the input image from the color estimator with different threshold array values for an edge pixel can be generated by a halftoning module. A binary domain resolution expansion can be applied for a non-edge pixel. A final output for each pixel can be selected from a resolution expanded result and/or from the result of the halftoning for the edge based on the edge tag with respect to that pixel.

摘要： What is disclosed is a system and method for determining an orientation direction of a color edge at a given pixel location in a binary color image. The orientation direction of the color edge is determined from eight pixel counts with each pixel count being a total number of pixels in each of eight regions of a window centered about a candidate pixel which resides along the color edge. The eight regions are associated with 8 compass points. The orientation of the edge is determined by a 1st, 2nd and 3rd tier control bits which are based upon the pixel counts of each region. The 1st, 2nd and 3rd tier control bits collectively form a 3-bit word. The 3-bit word defines the orientation direction. The teachings hereof provide an efficient way of performing binary edge orientation detection by making uses of intermediate results to simultaneously encode the edge orientation.
