IMINAR

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. Using the left- and right-arrow ( ) buttons,

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 4-4.

Figure 4-4. Typical Gray Bar Pattern for Adjusting Contrast

Select Contrast from the Picture menu. Using the left- and right-arrow ( ) buttons,

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.
