    摘要: An input scanner, such as used in a digital copier, accepts original documents on sheets of any number of possible sizes within a single job. The video output of the scanner is applied to an algorithm to determine the length, along a process direction, of useful image data on each sheet. From such a determination, a size of output copy sheets can be automatically selected, or the image can be automatically changed in size in subsequent processing. A prescan of the original documents is not required.

    摘要: In a mixed raster content (MRC) image data format, where a separation plane is used to define portions of the image to compressed in a lossy or lossless manner, edge pixels are identified in the separation plane. Each edge pixel is modified to assume a maximum luminance and most neutral chrominance found among neighboring pixels. The modification of the edge pixel data minimizes artifacts such as fringe effects when the image data is compressed and subsequently decompressed.

    摘要: What is disclosed is a system and method to improve the black and white image quality of tag-based color imaging systems in a color image path by making use of the additional two channels available. The present method exploits the resources of the two un-utilized channels during black and white processing. The single channel black-and white image is replicated into all three channels at the output of the storage memory. Segmentation tags are fed into each channel to control the image processing. Additional filters, TRCs and rendering methods will be available due to processing in all the 3 channels. Resources may additionally include such things as: filters, TRC mapping, and halftoning modules. The video output from the output image processing is merged back based on the segmentation tags. Different de-screen filters with various cut-off frequencies and enhancement filters are applied to the image based on pixel classification. One example of such an application is to use different cut-off frequency filters for text-on-tint pixels and different halftone frequency pixels. The number of TRCs and halftone screens available per page has also increased by 3 times. The method also applies to any image path that has extra channels available for certain scanning/copying modes.

    摘要: The disclosed systems and methods pertain to the processing of large format images in a manner to avoid introducing imaging defects, and more particularly to dividing the large image into bands, processing these bands in parallel and then putting them back together in to create the final processed image. The methods include the use of overlapping the image bands, padding of the bands prior to processing and the redefinition of image values at common boundaries of the bands to minimize or eliminate visible defects.
