Digital correction for alignment of a plurality of color channels of a color image forming device

A method of digital correction for alignment of a plurality of color channels, comprising:

• reading pixels at a first resolution from one of a plurality of color channels;
• choosing a source correction pixel from the pixels;
• scaling the pixels to a second resolution;
• making a correction determination whether a correction is to be made,
• wherein when a correction is to be made, making a modification determination whether an addition correction or a subtraction correction is to be made;
• and
• performing the addition correction or the subtraction connection based on the correction determination and the modification determination,
• wherein the addition correction or the subtraction correction is performed using the source correction pixel.

A system of digital correction for alignment of a plurality of color channels, comprising:

• a clock signal generator to generate a scaling clock signal;
• a section index unit to divide a sequence of pixels read from one of a plurality of source color channels into at least one section;
• a position index unit to store a position index within the section;
• a correction index unit to provide a correction index;
• a compare index unit to determine whether the position index corresponds to the correction index;
• a scaling and correction unit associated with each of the plurality of source color channels,
• wherein the scaling and correction unit comprises the section index unit, the position index unit, the correction index unit, and the compare index unit;
• and
• at least one controller interface to provide scaling and correction parameters to a plurality of the scaling and correction units.
