This sets the fastest value of a shutter speed when AUTO is set.
The MANUAL, M. ExDR, A. ExDR set value is displayed as “- - -”
and cannot be changed. The higher the shutter speed becomes,
the more smear phenomenon is emphasized, which is peculiar to
the CCD.
[Set values: 1/1000, 1/2000, 1/4000, 1/10000, 1/20000, 1/40000, 1/100000]
This sets the signal level of the composing high-speed shutter during
ExDR mode. This is set according to the brightness of a subject.
When using M.ExDR, be sure to set M.ExDR SPEED in advance.
When the SHUTTER/ExDR item is set to MANUAL or AUTO, “- - -”
appears, disabling setting.

[Set values: –5 to NORMAL to 5]
MEMO
• In the case of a subject with a large difference in the luminous flux
density, sometimes images do not change even if ExDR LEVEL is
varied. However, this occurrence is a peculiarity of the unit and is
not a malfunction.
This sets the composing high shutter speed when ExDR is set to
M.ExDR. Set the shutter speed in order that a subject with a high
luminous flux density (outdoor, etc.) may come out most clearly. This
is displayed as “- - -” during MANUAL, AUTO or A. ExDR and cannot
be set.
[Set values: 1/500, 1/1000, 1/2000, 1/4000, 1/10000, 1/20000]
This sets a maximum gain of the AGC (Automatic Gain Control).
OFF:
When the AGC function is not used.
10dB:
When luminous energy is insufficient.
20dB:
When luminous energy is extremely insufficient.
SUPER:
When brightness is insufficient even when it is set to 20dB.
• If the gain is increased, the screen gets rough in a dark place.
• If it is set to SUPER, it can sometimes consume operation time to
cope with a drastic level change.
Used when brightness is low even when setting the AGC MODE.
(Functions regardless of the AGC MODE setting.)
OFF: LOLUX MODE is off
ON: LOLUX MODE is on (+6dB)
This item makes up a sensitivity should be heightened automatically
when a subject becomes dark.
In case of the X32 AUTO, the sensitivity is automatically heightened
up to 32 times continuously as compared with standard.
As the sensitivity becomes higher, the shutter speed becomes lower,
resulting in unnatural motion.
If SHUTTER/ExDR is set to MANUAL or the M.ExDR,
“- - -” will appear, disabling the SENSE UP function.
[Set values: OFF, X2 AUTO, X4 AUTO, X8 AUTO, X16 AUTO, X32
AUTO]
MEMO
• When the magnification of SENSE UP is enhanced, the screen
can become coarse or whitish, or whitish flaws can emerge
sometimes, but this is not abnormal.

BLC
This item sets the order in which the AGC and slow shutter
speed decrease function when the object brightness
becomes low.
When the item AGC MODE or the item SENSE UP is set
to OFF, “- - -” will appear, disabling any setting.
MOTION: Priority is given to motion.
This is suitable to a subject with quick motion,
since the AGC (automatic gain control) functions
with priority when the subject becomes dark.
PICTURE: Priority is given to image.
When the subject becomes dark, SENSE UP
(sensitivity goes up) functions with priority,
offering suitability that gives priority to image.
Sets the backlight compensation function. Set when a
bright light source, etc. is placed in the same direction as
the subject.
If the item SHUTTER/ExDR is set to the M.ExDR or the
A.ExDR, “- - -” will appear, and the BLC does not function.
OFF: The backlight compensation function does not work.
AREA 1 to AREA 4: When the SET button is pressed, the
fixed light metering areas are displayed. Select one of
the four types. (Indicated positions on the screen are rough
guides. Execute required settings after checking and
confirming the functions on actual images.)
EDIT 1 to EDIT 2: When the SET button is pressed, the
user light metering areas are displayed. Select one of the
two types.
