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 par ts of the subject… increase the value To give priority to the high-brightness par ts 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)

Functions and set values

PRIORITY

This item sets the order in which the AGC and slow shutter

 

speed decrease function when the object brightness

 

becomes low.

 

If B&W item of the B&W/COLOUR mode is set to AUTO, and the

 

AGC MODE item or the SENSE UP item 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.

BLC

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.)

SENSE UP

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.
