Figure 2-36. Brightness-Contrast Custom Control

The Brightness-Contrast custom control indicates the current value of the Brightness

setting by means of a horizontal solid black line. The Brightness-Contrast custom

control indicates the current value of the Contrast setting by means of a vertical solid

black line. When Auto Brightness is enabled, the black lines (along with the slider) are

automatically adjusted to reflect the automatic brightness adjustment.

The Brightness-Contrast custom control indicates the current acceptable range of

detected brightness and detected contrast values by means of a rectangle with solid

blue lines. This box shows you the region of acceptable Brightness and Contrast

values. The box is centered on the 50-50 baseline settings for Brightness and Contrast,

with the borders representing the Brightness and Contrast threshold values from the

VirtualReScan Administration Utility dialog box. Valid VRS-detected values must fall

within the blue box. VRS detected values that fall outside the blue box borders are

invalid and they generate warnings.

Brightness Text Box

When the VRS Interactive Viewer is launched, the Brightness numeric text box on the

Clarity panel indicates the current Brightness setting. If desired, the Brightness setting

may be changed manually using the Brightness numeric text box. Brightness may be

set from 0 (very dark) to 100 (very bright) for black and white, grayscale, or color

images. Keep in mind that the manual brightness setting is not shared between black

and white, grayscale, and color modes. Changing the value of the manual brightness
