surface, do distinguish over that disclosed or suggested by
Femal.
Claim 7 recites the photoreceptive surface and laser
source, along with an image data source and a two dimensional
interpolator for processing the image data. But the claim
further recites that once the resample value and associated
two dimensional slope information is obtained, this
information is "used to control modulation of the laser source
and its directed laser light spot." Thus, we do not have a
situation here where the processing is the same in both Femal
and the instant invention and the question is merely the kind
of display (CRT or laser printer) to which the output is sent.
Rather, the instant claimed subject matter is more specific.
It sets forth a photoreceptive surface and a laser source and
then determines certain information through processing in the
interpolator and actually uses that information to relate back
to the photoreceptive surface and laser source and control
modulation of the laser source and its directed laser light
spot upon the photoreceptive surface. Thus, the claimed
processing is used to actually control the laser source. This
