[0068]Assume the picture is transformed into a positive color print. We first scan this into a digitized form via a normal high quality back and white scanner with a typical photometric spectral response curve. (It is possible to get better ultimate signal to noise ratios by scanning in each of the three primary colors of the color image, but this nuance is not central to describing the basic process.)

[0069]Let us assume that the scanned image now becomes a 4000 by 4000 pixel monochrome digital image with a grey scale accuracy defmed by 12-bit grey values or 4096 allowed levels. We will call this the “original digital image” realizing that this is the same...
