and which pixels are not as important (lines 3-6 of column 5). Reinhardt does not
disclose modifying the tags and/or the parameters associated with the tags of
formatted information defined by a markup language. Helman discloses
modifying tags and/or the parameters associated with the tags of formatted
information defined by a markup language in a television signal chrominance
adjustment method (lines 57-67 of column 2 and lines 8-12 and 51-58 of column
4). Helman teaches the foreground color is modified such that the difference
between the foreground luminance Yf and background luminance Yb is increased
by the same scaling factor used to reduce the chrominance (lines 51-58 of
column 4 and lines 15-25 of column 5). The scaling of luminance/chrominance
affects the power consumption levels of display. By reducing the
luminance/chrominance, the intensity of bright pixels must be reduced. This
results in a reduction of power to be achieved. Helman further teaches the
setting of colors has advantages in visual clarity, as it allows the manufacturer to
set colors which minimize artifacts between foreground and background colors
(lines 35-38 of column 4). A minimization of artifacts will result in reducing the
number or bright pixels. Artifacts are well known in the graphic arts as unwanted
added noise. It would have been obvious to one of ordinary skill in the art to
utilize the teaching of Helman to provide an improved method and system for
presenting color television signal by minimizing display artifacts while preserving
the relative visual contrast between foreground and background (lines 46-55 of
column 1, Helman).
While we concur with the examiner’s findings directed to the Reinhardt, we
disagree with the examiner’s findings directed to Helman and the examiner’s
conclusions based upon the combined teachings of the references.
However, before we consider the teachings of the references applied we first
determine the scope of the claims. Independent claims 1 and 23 both contain the
limitations of “formatted information for presentation on the display device, the formatted
information being defined by a markup language having tags and parameters
associated with the tags” and “modifying the tags and/or the parameters associated with
the tags of the formatted information to reduce the number and/or intensity of bright
pixels in a display format of the formatted information to produce modified formatted
