for the sake of shortness. Thus a picture in two or
more colours can appear at the output of
transforming device 38. A uni-coloured picture
(plus a different background colour) can also
appear, but this is already known.
(Page ll, lines 14-23.) This description says nothing about
the structure or components of transforming device 38.
Although the specification describes the function of
transforming device 38 as responding to control signals from
various components to effect a color change in certain output
characters, there is no descrip- tion of whether this is done
by a “color look-up table” or by some other kind of circuitry.
It is not even clear that the protocol used to transform
colors would come from the trans- forming device 38 itself, or
from some external control circuit such as the histogram
former 32, character generator 36 or control unit 54.
As the Examiner noted on page 9 of the answer, “[a]
trans- forming device is not always a look-up table,” and it
could be
any number of circuit elements including discrete logic
devices, analog devices with A/D converters, or a
microprocessor which calculates an algorithm for color
