Use the Color Correction web page ( Figure 15 on page 37 ) to make RGB
gain, offset and gamma correction adjustments and control the Split Screen
function.
The Color Correction processing must be enabled before adjustments can
be made. Select the
VCC Enable checkbox to enable these controls.
Color Correction
The Color Correction section provides the following RGB controls:
• Gain Adjustments – set the gain from 0 to 200% for the R, G, and/or
B channel with the corresponding control or adjust all of the gains
together by adjusting the
Total Gain control.
• Offset Adjustments – set the offset from ± 100% for the R, G, or B channel
with the corresponding control or adjust all of the offsets together by
adjusting the
RGB Offset control.
• Gamma Correction – set gamma correction with the R Gamma Correction ,
G Gamma Correction , and/or B Gamma Correction or adjust all channels
together using the Total Gamma Correction control. Raising the gamma
above 1.0, brightens the gray intensity. Lowering the gamma below 1.0,
darkens the gray intensity.
Split Screen
Use a horizontal or vertical split screen to compare the unprocessed input
video (top or right) to the processed output video (bottom or left). This
control is duplicated and tied together with the Split Screen controls on the
System Config and Video Proc web pages. Changes made on any one of the
Split Screen controls will control all three screens.
• Split Enable – enable the split screen by checking the Split Enabled
checkbox.
• Orientation – select the orientation of the split screen with the Vertical or
Horizontal radio button.
• Position – use this control to set the amount of horizontal or vertical split
(10 to 90%) of unprocessed video to appear on the screen.
