of counting. The claims require counting of a pixel clock or valid pixels, which is
not met by counting edges of the horizontal synchronizing signal to determine its
frequency as is taught by Kesatoshi (see column 5, lines 44-45). While we do
find that Reddy teaches, in column 8, lines 41-42, that “the number of pixels in
each horizontal line can be determined to determine the format of the video
signal” and, in column 8, lines 27-29, “[t]he number of horizontal lines per image
is detected by counting a number of HSYNC pulses which occur between
adjacent VSYNC pulses.” Reddy teaches that these two methods are
alternatives. Further, we consider the examiner’s statement that column 9, lines
13-41 of Reddy teach determining the active horizontal and active vertical
resolution to be misplaced as we find that the cited section of Reddy teaches
capturing the video signal after the video format has been determined. Thus, we
do not find that Reddy teaches that both the counting of pixels in the horizontal
line and a counting of the vertical resolution are performed to determine the
active resolution.
