4-5 Setting the Image Quality (continued)
Photo-metering Area
1
Compression Rate
Sets the image compression rate. A lower
compression rate means a higher image
quality. However, with a reduced compression
rate, data volume also increases.
This setting is not available for MPEG4.
Value range: 1 to 7 (Set to “2” at the factory)
2
White Balance
Auto
: Automatically adjusts the white
balance, the standard for color
saturation. Factory set.
R gain
: To manually adjust the white bal-
ance toward more red intensity.
Value range: 0 to100
B gain
: To manually adjust the white bal-
ance toward more blue intensity.
Value range: 0 to100
3
Shutter Speed
1/60
: Normal speed. Factory set.
1/100
: This reduces image flickers due
to fluorescent lighting in areas
where the commercial power fre-
quency is 50 Hz.
4
Saturation
Adjusts color saturation. A smaller value
makes colors less dense. Set to “25” at the
factory
5
AGC, AES, BLC
AGC
: Automatically adjusts the gain in
accordance with the brightness.
Factory Set.
AES
: Automatically adjusts the shutter
speed in accordance with the
brightness. Only for a manual iris
lens.
BLC
: Back light compensation. When
there is a bright light source in the
background of the object, VN-C10
adjusts the weighted zone.
Note
●
AES cannot be turned on when AGC is
set to [OFF].
●
AES cannot be turned on if the shutter
speed is set to [1/100].
●
BLC cannot be turned on when AGC is
set to [OFF].
●
Do not use AES with a DC IRIS lens. It
may cause flickering.
6
Default
Returns all values, except that for iris level,
for image quality to those set at the factory.
7
Iris level
Brightness adjustment for a DC IRIS lens.
A smaller value makes images darker, closing
the iris.
