Set value
Sets the speed of the electronic shutter.
Set value : 1/60, 1/100, 1/250, 1/500, 1/1000, 1/2000, 1/4000,
1/10000
Notes
• To reduce flickering that occurs under fluorescent
lighting, set the shutter speed to 1/100 if your local power
supply frequency is 50 Hz, and to 1/60 if it is 60 Hz.
• The higher the shutter speed, the more prominent will
be the smear phenomenon. This is a phenomenon that
is characteristic of CCDs, whereby white stripes appear
at the top and bottom of a bright light source.
Sets the maximum gain of the AGC (Auto Gain Control), which
electronically increases the gain when the object is under low
light conditions.
OFF
: Disable AGC.
10 dB : Increase gain by a maximum of 10 dB according to
the brightness of the object.
20 dB : Increase gain by a maximum of 20 dB according to
the brightness of the object.
Note
• The screen may appear grainy at dark places when the
gain level is increased.
Sets the backlight compensation function. Use this setting when
an object appears dark using the Auto Iris function due to the
presence of a bright light source behind the object. This func-
tion makes it possible to place an unnecessary light source
outside the photometry area.
OFF
: Disable BLC.
