•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 “- | |

[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)

PRIORITY | This item sets the order in which the AGC and slow shutter |
| speed decrease function when the object brightness |
| becomes low. |

| 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. |

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, “- -
•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.
