Appeal No. 95-1423
Application 07/928,883
discloses a control unit (Figs. 2 and 4) containing a
“converter” which “converts first code words assigned to the
relatively dark colours into second code words which are
assigned to the cor- responding brightened colours” (page 5,
lines 15-17). This converter is analogous to the claimed
color transforming means and functions in at least two states
whereby the converter can either, in a first state, forward
the color signals unchanged to the image repetition store
(page 15, lines 7-15) or, in a second
state, produce additional brightness signals to brighten the
color signal associated with certain characters (page 15,
lines 1-6).
Moreover, the converter UM1 (Fig. 4) is described as able
to “contain a store in which the background colour which
applies to the character array in question is intermediately
stored, and the brightening of the relatively dark colours
can take place in dependence upon the contents of said store”
(page 15, lines 12-15). We agree with the examiner that this
suggests a color look-up table to one of ordinary skill in the
art, since the transforming device acts in accordance with the
instructions stored in UM1.
