Adjusting video image contrast threshold
The contrast of an edge is shown by the height
of the gray bar on the right side of the screen
when the crosshair probe is positioned over
an edge. The contrast threshold required for
edge recognition is shown by the yellow ar-
row and must fall within the gray bar. When
the threshold adjustment is unlocked in the
VED setup screen, the contrast threshold is
increased or decreased by raising or lowering
the yellow arrow on a contrast bar.
