Functions and set values

Initial value

 

 

 

 

 

FAST LIMIT

This sets the fastest value of a shutter speed when AUTO is set.

1/100000

 

 

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]

 

 

 

 

 

 

ExDR

This sets the signal level of the composing high-speed shutter during

NORMAL

 

LEVEL

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.

 

 

 

 

 

 

M.ExDR

This sets the composing high shutter speed when ExDR is set to M.ExDR.

1/4000

 

SPEED

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]

 

 

 

 

 

AGC MODE

This sets a maximum gain of the AGC (Automatic Gain Control).

20dB

 

 

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.

 

 

 

 

 

SENSE UP

This item makes up a sensitivity should be heightened automatical-

OFF

 

 

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, X24

 

 

 

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.
