Contrast
Contrast adjusts the ratio between white and black signal levels and is effective as a gain control.
The difference between this and the Brightness control is that this adjusts the difference between
the brightest and darkest part of the image. Note that all displays have a maximum white level.
Going beyond this level only “clips” the upper gray levels and you will lose color resolution at the
brighter levels. Adjust this control up until you see the brighter levels of the image begin to wash out,
at this point, back it down just below that point. The default setting is 0 (midrange).
Saturation
The iScan VP50 allows you to control the saturation of the image independent of the display.
Saturation is the same as the “Color” control on most TVs and controls the richness of the color in the
image. The default setting is 0 (midrange).
Hue
As with Saturation, hue can also be controlled independent of the display. Hue is the same as the
“Tint” control found on most TVs and controls how colors are displayed in the image. The Hue control
is not available for Component or PAL/SECAM inputs. The default setting is 0 (midrange).
Sharpness
The Sharpness setting adjusts the sharpness of the selected input signal. The default setting is 0.
Y/C Delay
Sometimes there is a lag between the Luminance (Y) and the Chrominance (Pb/Pr or Cb/Cr) of the
video signal. This causes a color “smearing” because the color component of the image is not lining
up properly to the black and white luminance component of the image. The iScan VP50 can compen-
sate for these errors in the source signal by shifting the phase of the Y with respect to the C, forward
or backward to align them properly. Use the q and p buttons to adjust the phase and observe
the effects on your display to obtain the optimal setting. The default setting is 0. The included VRS
Optimization and Evaluation DVD includes a test pattern to assist with this adjustment in the
‘Picture Controls’ under the ‘Static Patterns’.
Chroma Filter (Auto CUE-C™)
This feature removes chroma upsampling errors (CUE) found in video sources which have been MPEG
encoded and then improperly decoded.
• Off - No chroma ltering. Use this setting if the source does not have a CUE problem.
• On - Chroma ltering is always on. Use this setting if the source is known to have a CUE problem.
• Auto - Automatic chroma error detection and correction. Use this setting when you don’t know
if a source has a CUE problem. Also use this setting for all digital sources which use MPEG2
decoders (DVD players, digital satellite receivers, and so on) as it will also detect and correct
chroma errors created by all sources of this type when the source is encoded as interlaced
(also sometimes called Interlaced Chroma Problem, or ICP).

Test Patterns
The iScan VP50 has 35 internal test patterns to assist in the setup of your individual sources and
display. To learn more about how to use the internal test patterns, refer to the section Setting up an
iScan VP50 Using the Internal Test Patterns and the VRS Optimization and Evaluation DVD.
To turn the test patterns on and off, use the Test Pattern On/Off button. To navigate backwards and
forwards through the available test patterns use the t and u buttons, respectively.
