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： 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.

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.
