Patent abstract
A multiplied resolution, single pass flatbed scanner having a charge-coupled device (CCD) sensor of n pixels with a scan width of W, which gives a subject pixel center to center distance of W/n, two independently moveable carriages capable of incremental advancement of W/2n so that for each read of a scan line Y, two reads of all segments of X along the scan line of Y are taken, with each segment of X having a width of half pixel distance, W/2n, and each line Y having a height of half pixel distance, W/2n, to thereby double the resolution.
