Functions and set values
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.
To give priority to the low-brightness parts of the subject...
increase the value
To give priority to the high-brightness parts of the subject...
decrease the value
[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.
• When the item "B&W" is set to "AUTO", [SUPER] is displayed when
the item "AGC MODE" is set to "SUPER", and [20dB] is displayed for
other settings. Increase the gain up to the value displayed.
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 automatical-
ly 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.
• When the item SENSE UP is set other than to OFF, a flicker can
occur under a fluorescent lamp, mercury lamp, etc. However, this
occurs by principle of SENSE UP, and therefore this is not a
malfunction.
