摘要： What is provided herein is a novel system and method for estimating the amount of color in a document. In one embodiment, a binary CMYK input image is received. Each of the CMYK plane is received at an offset from the previous plane, i.e., the 4 planes are not received simultaneously. Each plane is divided into M×N tiles. Pixel values of all four planes are examined separately and the number of on-pixels is counted for each plane. The number of on-pixel counts for each tile are aggregated for each plane. Total on-pixel counts are used to estimate the total number of white, black, color, and gray pixel counts. The total counts for all planes are used to estimate the amount of color. A document is determined to be color if the amount of color exceeds a predetermined threshold. A color billing strategy is determined based on the estimated color amount.

摘要： What is provided are a novel system, method, and computer program product for estimating the amount of color in a document to be printed, with the capability to handle composite black. A color billing strategy can be dynamically determined based on the amount of color in the document. In one embodiment, a contone CMYK image is examined and the level of color is estimated based on information extracted from the four planes simultaneously. More specifically, it examines the pixel values from all the four planes to calculate the number of white, black, color, and gray or neutral pixel counts. Input CMYK values can be pre-adjusted via a look-up table to take into account neutral balance characteristics. The difference among the adjusted color values is compared against a threshold that is input level dependent. Color is further subdivided into fuzzy colors to handle highlights and neutral areas.

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： 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.
