[Wide dynamic range (WDR)]
Select “On” or “Off” to determine whether or not to activate the wide dynamic range function.
This function compensates brightness so that it produces clearer images even if objects have various illumination intensities.
•
On: The wide dynamic range will work.
•
Off: The wide dynamic range will not work.
•
Default: Off
Note
•
When the following are observed depending on the light condition, select “Off” for “Wide dynamic range (WDR)”.
–
When flickering appears or the color changes on the screen
–
When noise appears in the brighter area on the screen
[Adaptive black stretch]
Select “On” or “Off” to determine whether or not to activate the darkness compensation function. The darkness compensation function can make darker parts of images brighter by digital image processing.
•
On: Activates the darkness compensation function.
•
Off: Deactivates the darkness compensation function.
•
Default: On
IMPORTANT
•
When “On” is selected for “Adaptive black stretch”, noise in the darker parts may be increased, and parts around borders between the darker parts and the brighter parts may become darker/brighter than the other darker/brighter parts.
Note
•
When “On” is selected for “Wide dynamic range (WDR)”, “Adaptive black stretch” is unavailable.
[Back light compensation (BLC)]
Select “On” or “Off” to determine whether or not to activate the back light compensation (BLC) function. When “On” is selected for “Wide dynamic range (WDR)”, this setting is unavailable.

•
On: Mask areas will be set automatically.
•
Off: Mask areas will not be set automatically. It is necessary to set them manually.
•
Default: Off
[Mask area]

•
ELC: Uses shutter speed adjustment to control light.
•
Default: ELC
[AGC]
Select a method of gain adjustment from the following.
•
On(High)/ On(Mid)/ On(Low): When the luminance of the subject becomes darker, gain will be automatically increased and screen will become brighter. “High”, “Mid” and “Low” are indications of gain level.
•
Off: Images will be captured with the fixed gain level.
•
Default: On(Mid)

•
Default: Max.1/30s
IMPORTANT
•
When a value with an interval longer than “Max.1/30s” (Max.2/30s/ Max.4/30s/ Max.6/30s/ Max.10/30s/ Max.16/30s) is selected for “Maximum shutter”, the frame rate may become lower. Noise or white dots (blemishes) may sometimes appear.
Note
•
When “Max.16/30s” is selected, for example, sensitivity will automatically be increased up to x16.
•
When “Off” is selected for “AGC”, values with an interval longer than “Max. 1/30s” (Max.2/30s/ Max.4/30s/ Max.6/30s/ Max.10/30s/ Max.16/30s) will become unavailable.
