AGC MODE
●
When the item “B&W” is set to “AUTO”, [SUPER] is displayed when the item “AGC MODE”
is set to “SUPER”, and [20 dB] is displayed for other settings. Increase the gain up to the
value displayed.
●
Note that increasing gain affects picture quality.
●
When the “SUPER” setting is used, the AGC operation may take a while to adjust to
sudden drastic changes in the brightness level.
MEMO
Sets the maximum gain of the AGC (Auto Gain Control), which electronically in-
creases the gain when the object is under low light conditions.
OFF
: Turns the AGC off.
10 dB : According to the brightness of the object, gain is increased by up to 10 dB
20 dB : According to the brightness of the object, gain is increased by up to 20 dB
SUPER : Use this setting when brightness is still insufficient under the “20 dB”
setting.
10 dB
●
To reduce the flickering which occurs under fluorescent lighting, set the shutter speed
to 1/50 if your local power supply frequency is 50 Hz and to 1/120 if it is 60 Hz.
●
When a high shutter speeds are used, white stripes may be observed above and
below bright objects. This is called the smear phenomenon and is usual to CCD
cameras.
