NOTE:
All Video Proc controls affect the video in real time. H&V frequency bands will
cause hits to the video while a new filter is loaded.
Video Proc
RGB Clip:
The
RGB Clip
parameter controls RGB clipping/colour legalization process. When set to
enable
, the module will clip any illegal levels of R, G, and B (individually) to their respective Black
and White Levels. If disabled, then the illegal values are passed unmodified. This control is normally
set to
Disable
in order to allow for Super Black or other test patterns to pass through the module.
Gain Levels:
There are eight controls that set the gain of the video. With these controls, the user
can adjust the gain of the 3 components in either the Y Cr Cb domain or the R G B domain over a
range of 50% to 100% in 0.1% steps. Gain adjustments in the YCbCr domain are made first,
followed by gain adjustments in the RGB domain. Illegal values are clipped after gain adjustments.
Y Gain:
Ranges from –50% to 100% in 0.1% increments.
Cb Gain:
Ranges from –50% to 100% in 0.1% increments.
Cr Gain:
Ranges from –50% to 100% in 0.1% increments.
R Gain:
Ranges from –50% to 100% in 0.1% increments.
G Gain:
Ranges from –50% to 100% in 0.1% increments.
B Gain:
Ranges from –50% to 100% in 0.1% increments.
Saturation Gain:
Ranges from –50% to 100% in 0.1% increments.
Video Gain:
Ranges from –50% to 100% in 0.1% increments.
DC Offsets:
There are six controls that set the DC Offset of the video signal. With these controls,
the user can individually adjust the DC offset of Y, Cr and Cb with a range of +/- 200 quantization
levels and individually adjust the DC offset of R, G and B with a range of +/- 200 quantization levels.
Offset adjustments in the YCbCr domain are made first, followed by offset adjustments in the RGB
domain. Illegal values are clipped after offset adjustments.
Y Offset:
Ranges from –200 to 200 quantization levels in 1 level increments.
Cb Offset:
Ranges from –200 to 200 quantization levels in 1 level increments.
Cr Offset:
Ranges from –200 to 200 quantization levels in 1 level increments.
R Offset:
Ranges from –200 to 200 quantization levels in 1 level increments.
G Offset:
Ranges from –200 to 200 quantization levels in 1 level increments.
B Offset:
Ranges from –200 to 200 quantization levels in 1 level increments.
Hue:
With this control, the user can adjust the Hue of the video signal. The hue adjustment range is
from –180 to 180 degrees in 0.1 degree increments.
Gamma Adjust:
The
Gamma Adjust
control enables and disables the gamma adjustment
functionality of 7815 series modules. When enabled, the module will allow the user to adjust the
gamma level. If disabled, then the gamma levels are set to 0.
Gamma Level:
With this control, the user can adjust the overall Gamma correction factor from
-128 to +127 in increments of 1.
Red, Green, Blue Gamma Levels:
With these controls, the user can individually adjust the Red,
Green, and Blue Gamma levels from –128 to +127 in increments of 1.
