A scanner calibration system is provided. The scanner calibration system includes memory configured in a format to store therein encoded gain and offset parameters. Such a configuration reduces the amount of required memory for the scanner calibration system without a compromise of performance.

Reduced memory scanner calibration system and method

A scanner enables full productivity and individual image size detection, without user intervention for mixed size originals in both simplex and duplex scanning modes. The scanner provides high-productivity single pass scanning while preserving the image size for each of the document scanned. In addition, the scanner may support duplex scanning by adding a second image sensor, for example, in the document handler. Methods of scanning are also provided.

High productivity single pass scanning system

In a system for processing full-color image data, such as within a digital color printer or copier, a four-channel architecture is used. Three of the channels handle image data relating to primary color planes, such as CMY. In the other channel, values relating to the K value which goes with the CMY values for each pixel alternate with a B value, suitable for pure monochrome rendering of the pixel in the image. When it is desired to print or display the image in monochrome, the B values are isolated from the K values.
