Manual Image Adjustment
VRS provides the option to manually adjust the settings for an image or images. You
can use the Clarity tab to make the adjustments.
Brightness-Contrast Custom Control
The Clarity tab includes custom controls (visual markers) to assist you in identifying
the optimal range for Brightness and Contrast.
Figure 2-37. 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
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.
