Color Balance
Select this submenu to work with aspects of color - adjust for saturation and overall hue in video
signals, or adjust gamma or temperature in any signal.
Color
(SHORT CUT: Press and adjust the slidebar.)
“Color” adjusts color saturation level, or the amount of color in a video image. For
example, setting Color to “0” produces a black and white image. If Color is set too high,
the color levels in the picture will be over-powering and unrealistic. Use or
until the desired color saturation level is displayed. NOTE: COLOR is not available in
the RGB mode.
T
int
(SHORT CUT: Press and adjust the slidebar.)
“Tint” adjusts color hue to obtain true color reproduction of NTSC video signals. Use
or until you reach optimum balance of red-to-green in your image. It is
best to adjust tint while displaying a proper SMPTE color bar test pattern-otherwise, it is
recommended that tint remain at its default setting. NOTE: TINT is not available in the
RGB mode.
Set Color
Balance
“Color Balance” applies either a preset color temperature
(3200K, 5400K, 6500K, or 9300K) or any previously defined
Infinite Adjustable or “Custom” color temperature. All temper
atures aremeasured in degrees Kelvin and represent the “col
oration” (reddish or bluish) of the whites displayed by the pro
jector-thelower the temperature, the more reddish the whites,
the higher the temperature, the more bluish the whites. NOTE:
Custom temperatures (“Custom” or “Infinite Adjustable”) can
be defined in theAdvanced Color Temperature menu-until then,
these choices all default to 6500K. See Section 3.7, Adjusting
System Parameters and Advanced Controls.
Gamma Curve
NOTE: Gamma does not normally require adjustment and is intended for experienced
users only.
The “Gamma Curve” option affects the shape of the gamma curve representing the levels
and types of grays available between minimum input (black) and maximum (white).
Generally the best gamma curve is one that produces maximum contrast, brightness and
color performance. See Selected Gamma Curves on the following page.
