M.21.1.2 Main Unit - VM Unit Settings (Video
Display Adjustments)
(1/4)
CHANNEL
Select the channel set in the video window from 0 to 3.
Mode
Select the video input mode from [Color] and [Mono].
Brightness
Set the brightness of the screen. The available range is between
0 and 15.
Contrast
Set the contrast of the screen. The available range is between 0
and 15.
Color
Set the color tone of the screen. The available range is between
0 and 15.
Reset
Reset the settings of the selected channel to the initial
values.
(2/4)
CHANNEL
Select the channel set in the
video window from 0 to 3.
Hor.Pos.
Set up the horizontal position (-8 to +7) of the video input
signal.
Ver.Pos.
Set up the vertical position (-8 to +7) of the video input
signal.
Decim.Filt.Cir
Turn ON/OFF the decimeter circuit included in the decoder. When
monochrome signals are used, the image quality may be better when
the signal processing filter (decimeter) is not activated. Under
normal conditions, leaving this option set to [ON] presents no
problem.
Clamp.Cir.Curr
Select the current setting for the clamp circuit from
[Low] and [High]. If the video input signal is
outside of the specifications, the synchronization signal or the
black level cannot be detected, resulting in an unstable screen
display. In such a case, changing the internal current for the
clamp circuit may improve the screen.
Reset
Reset the settings of the selected channel to the initial
values.
(3/4)
CHANNEL
Select the channel set in the
video window from 0 to 3.
Gain Control
Set the gain control of the digital amplifier circuit. This
setting is common to all channels.
Gain
When the gain control is set to [Man] (Manual), set [Gain] (amplification factor) from
-32 to +31.
Offset
When the gain control is set to [Man] (Manual), set [Offset] (black level) between -64
to +63.
Sync Slicing
Level
[Auto] or
[Man] (Manual) are the
available options.
Input field
[Sync Slicing
Level]. When this is set to [Man] (Manual), set up between 0 to
127.
Reset
Reset the settings of the selected channel to the initial
values.
(4/4)
CHANNEL
Select the input channel to which the video device is connected
from 0 to 3.
Y/C
Separ.Filter
Select the input Y/C
separation filter. When a vivid image is displayed and noise from
color signals is conspicuous, selecting [Trap] may decrease the noise. This
setting is common to all channels.
Color
Removal
Select whether to turn ON/OFF the color removal function
automatically or to turn it OFF forcefully.When the amplitude level
of color burst signals is small, the screen may be switched
automatically to show monochrome images. [OFF] setting displays images in
color. This setting is common to all channels.
Color
Control
Change the amplification factor of chroma signals. If the
amplitude value of chroma signals (including color burst signals)
is outside of the specifications and the adjustment functions have
no effect on the ability to obtain optimal images, setting this
item manually may be effective. This setting is common to all
channels.
Input
Sysnc.Mode
Set the depth level to detect synchronization signals. If the
depth of the synchronization signals of the video input is not as
deep as the specifications or if the signals fluctuate, the
synchronization signals are not detected, resulting in a screen
which does not lock vertically or horizontally. When this occurs,
adjusting the detection level may stabilize the screen. Under
normal conditions, leaving this option set to [Auto] presents no
problem. This setting is common to all channels.
Reset
Reset the settings of the selected channel to the initial
values.
