for distance determinations. A pertinent portion of this
reference is:
It should be noted that the use of
the term 'threshholding' throughout this
description is meant to encompass other ways
of making a distance decision between the
input optical density value and the output
optical density value.
The examiner’s correlation of this “distance” is inappropriate
when taken in context in the reference. Such a distance is
more aptly described as originally relied upon by the examiner
in accordance with the operation of the error determination
block 117 in respective embodiment Figures 1 and 2 of
Eschbach. This block is shown as a differential amplifier
which “calculates a difference between the average gray input
value generated at integrator 113 and average gray output
value output generated at integrator 111.” Column 6, lines 8
to 11. Again, there is no true distance determination between
pixels in the manner required by each independent claim on
appeal.
Assuming for the sake of argument that it would have been
