摘要:
Disclosed is a processor-implemented method for processing image data comprising a plurality of pixels and system for performing the method. The method includes the following acts: determining at least one type of data represented by the plurality of pixels, determining, for each type of data, a number of pixels from the image data representing that type of data in the image data, and determining a compression scheme for compressing the image data based on a relative or absolute amount of each type of data in accordance with a predetermined scheme. The type of data may be determined by received input (e.g., user selected type and compression quality) or by analyzing its pixels and comparing it to thresholds. Basing the compression technique on the data type allows for better selection of a compression technique (e.g., MRC or JPEG), and thus greater image quality, compression ratios, and file size.

Disclosed is a processor-implemented method for processing image data representing a document using an image processing apparatus. The processor receives image data, determines the classifications and counts of pixels in the image data (e.g., in device independent space that are degrees of neutral or non-neutral), classifies the image data into a category based on the determination of classifications and counts of pixels, and determines a billing structure for the image data based on the classification of image data. The classification can be performed on the image data prior to conversion into device dependent space. For example, by counting true color, neutral, non-neutral, and fuzzy color pixels and comparing them to thresholds, the image data can be classified as neutral or very colorful. By classifying images earlier in the image path, errors in billing are reduced.

Disclosed is a processor-implemented method for processing image data of a document using an apparatus. The processor determines pixel classifications and counts for each classification, classifies the image, selects a billing tier for which to bill the image, determines counts of pixels for marking to output the image (e.g., in device dependent space), and then can adjust from the selected billing tier to a different billing tier based on the image classification (e.g., and/or using determined counts of pixels for each classification and determined counts of pixels for marking). Counts of pixels can be adjusted using an offset, or calculated using a combination of the determined counts (e.g., combining counts from both independent and dependent spaces). By adjusting the tier at which to bill data, more accurate billing can be implemented for documents with contone or grayscale image data, for example, with greater customer satisfaction.

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.

A method and apparatus for configuring an image path of an image processing apparatus is herein described. The image processing apparatus includes at least an input terminal or scanner for inputting or scanning document into image data and an output terminal or printer for printing documents. The method includes selecting one of a plurality of output modes using a selection device associated with the image processing apparatus. Based on the selected output mode, an image path among a plurality of image processing elements of the apparatus is selected among a plurality of image paths. Each image path corresponds to one of the plurality of output modes. After a document is scanned with the scanner into image data, the image data is processed with the processing elements in the selected image path, and output or printed based on the processed image data.

摘要:
A method permitting an end user to recalibrate a color reproduction device. The color reproduction device includes a device for converting the native color values of the scanner into a device independent color space, a test target, and the desired values of each patch of the test target. The method includes printing the test target and scanning it with a scanner that forms a part of the color reproduction device. The device compares the desired values with the values obtained from scanning the printed test target to obtain a set of adjustment values to compensate for drift in the output of the color reproduction device. The compensation emphasizes restoration of the overall gray balance of the color reproduction device and can be implemented by modifying the tone reproduction curves or the halftone process used in the color reproduction device.
