PLUGE patterns vary but generally consist of some combination of black, white and gray
areas against a black background. The example above includes two vertical bars and four
shaded boxes.
Select Brightness from the Picture menu and press ENTER. Adjust the brightness so that:
• The darkest black bars disappear into the background.
• The dark gray areas are barely visible.
• The lighter gray areas are clearly visible.
• The white areas are a comfortable level of true white.
• The image contains only black, gray and white (no color).
Contrast: On your external test pattern source, select a stepped, gray-bar pattern like the
one shown in
Figure 4-3.
Figure 4-3. Typical Gray Bar Pattern for Adjusting Contrast
Select Contrast and press ENTER. Adjust the contrast to a point just below which the
white rectangle starts to increase in size.
Brightness and contrast controls are interactive. A change to one
may require a subtle change to the other in order to achieve the
optimum setting.
