references to arrive at the claimed invention.4 Although Kim teaches that
hue is determined by the phase difference between a burst signal and color
data of a video signal as Appellants indicate, generating the color signal C
(either via the color processor 117 or user selection using the color filtering
device) nonetheless involves generating and processing digital signals.
As shown in Figure 1 of Kim, signal processor 100 -- a system which
comprises color processor 117 -- is located between (1) A/D converter 114
and (2) D/A converters 118, 119. Although not shown in Figure 1, the color
filtering device is likewise located between the A/D and D/A converters
since the color filtering device, like the color processor, generates color data
that ultimately produces a color signal C in accordance with the user’s
selection. Although this color signal C is converted to an analog signal and
mixed with luminance signal Y for video output, the reference nonetheless
teaches providing a user-selectable color filter that will produce “filtered
image data” in the digital domain. The fact that the color data may relate in
some way to the analog video signal5 does not, however, detract from the
fundamental teaching that colors are selected in Kim using the color filtering
device to provide “filtered image data” in the digital domain.
We see no reason why the skilled artisan would not have applied a
commensurate color selection feature in Anderson’s system, particularly
since color adjustment is one of the filter options on the image editing screen

(noting that obviousness rejections can be based on references that happen to
anticipate the claimed subject matter).
5 For example, Kim indicates that the color data corresponds to the phase of
a burst signal (Kim, col. 2, ll. 60-62). Kim also notes that the phase
difference between a burst signal and color data of a video signal represents
hue (Kim, col. 3, ll. 19-20).
