Function & Setting
Sets the method of exposure detection to the ratio between
the average and peak values.
Large Average value
:Use this setting when areas other than the highlighted
areas are filled with dark. (Example: 10:0)
Large Peak value
:Use this setting when highlighted areas appear as
halation.(Example: 5:5)
Setting values : 10:0, 9:1, 8:2, 7:3, 6:4, 5:5
Sets the electronic shutter speed.
When the SENSE UP item is set, the only two values that
can be selected are 1/50 and 1/120.
When the item "ExDR MODE" is set to "ON", the available
settings for the SHUTTER are limited to 1/50 and 1/120.
Setting values : 1/60, 1/100, 1/250, 1/500.1/1000, 1/
2000,1/4000,1/10000
• To reduce the flickering which occurs under fluorescent
lighting, set the shutter speed to 1/60 if your local power
supply frequency is 60 Hz and to 1/100 if it is 50 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 cam-
eras.
Sets the maximum gain of the AGC (Auto Gain Control),
which electronically increases 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 insuffi-
cient under the "20 dB" setting.
• 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.
