present and perform the same selection as before until you have all the RGB
signals properly defined.
12.6 RGB Contrast (RGB Only)
Program Source [RGB1]
RGB contr. [100] 100 100
One desirable feature of an RGB signal is the ability to adjust the individual
signal components with minimal effect on the other components. With a CV
(Composite Video) or YC (Component Video) signal it’s not easy to make an
adjustment to one color without causing a knock on effect on another portion of
the image. With RGB images you can (for instance) have an image of green
grass and blue sky and make the grass bright green without having any effect on
the blue sky. The RGB Contrast LCD screen affords you the opportunity to make
such adjustments for each of your RGB Input Buttons.
The RGB Contrast Screen is selected by depressing the Menu Select knob one
time immediately after reaching the screen. This will cause the left-hand set of
brackets to flash, enabling the adjustment of the “R” or Red portion of the image.
Move the Menu Select knob Clockwise or Counter-clockwise until the desired
amount of Red enhancement or de-enhancement is reached. Pressing the knob
once places the new value in temporary memory. Rotate the knob one ‘click’ to
the right causing the middle set of brackets to start flashing. Press the knob once
and then adjust the “G” (Green) image characteristics, pressing the knob once
more to store that value. Finally, adjust the Blue component of the signal by
rotating the knob to the right, pressing it once and again moving the knob
Clockwise or Counter-clockwise until the desired amount of “B” (Blue channel)
adjustment is reached. Then press the knob a final time.
When you’re done, remember to press and hold the knob until you hear the
‘beep’ if you wish to make the changes permanent.
12.7 De-Interlace (RGB, CV, YC, SDI)
Program Source RGB1
De-int. [ AUTO]
An interlaced input consists of two fields separated in time. Both fields are
required in order to make up the full resolution input image, but since they are
sent one after the other, a moving image will have “motion artifacts” if the two
fields are simply combined together. The most common artifact is a blurring at
the point of maximum acceleration of movement within an image. The Scaler
provides some tools to minimize the effects of de-interlacing of an image.
