Abstract
The present invention is an apparatus and method that performs resolution conversion by averaging the pixel data produced by a sensor. The averaging operation includes storing 400 dots per inch (dpi) pixel data in alternating latches 94 and 96, adding the contents of the alternate latches using an adder 98 and dividing by two by transferring the carry and the most significant bits of the addition result to the next stage, thereby accomplishing a shift by right. The averaging includes an average of two adjacent pixels for a 200 dpi output, an average of four adjacent pixels for the 100 dpi output and a rolling average of two pixels for the 300 dpi output, where the rolling average has a repeat cycle of four pixels.
