Operating VRS

VRS User’s Manual

VRS provides the option to manually adjust the settings for an image or images. You 

can use the Clarity panel to make the adjustments.

Brightness-Contrast Custom Control 
The Clarity panel includes custom controls (visual markers) to assist you in 

identifying the optimal range for brightness and contrast.

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 

VRS 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
