OPERATION

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 Color 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.

Tint

(SHORT CUT: Press Tint 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.
