ALC Maintains the video level according to the object brightness. The priority of
motion (by AGC) or the priority of picture quality (by Sense Up) can be
selected. If both are set simultaneously, you can set their priority using the
[Priority] option.
AGC Sets the AGC (automatic gain control) level.
You can adjust the brightness of image according to the object brightness.
OFF : Disables the AGC function.
Mid : When the amount of light is insufficient
High : When the amount of light is particularly insufficient
[Set values: OFF, Mid , High ]
Memo:
●
If [Easy Day/Night] is set to "Auto", you cannot turn it "OFF". (VN-H137U,
VN-H237U)
●
If [Day/Night] is set to "Auto Low", "Auto Mid" or "Auto High", you cannot
turn it "OFF". (VN-H37U, VN-H237VPU)
●
The screen appears grainy at dark locations when the AGC function is in
use.
Sense
Up This function is used to raise the sensitivity level by lengthening the
exposure time.
You can specify the number of times by which the sensitivity level is to be
increased automatically when the object becomes dark. When
A
x16
B
is
selected, the sensitivity level will automatically increases continuously until it
is 16 times of the level when
A
OFF
B
is selected.
[Set values: OFF, x2 , x4, x8, x16, x32, x60 ]
Memo:
●
When the sensitivity is increased, the shutter speed drops and a moving
object appears unnatural.
●
Upon raising the sensitivity level, the screen may appear grainy or white,
or white defects may occur. However, this is not a malfunction.
●
When Sense Up is set to a value other than
A
OFF
B
, flickers occur under
the light of fluorescent or mercury lamps. This is not a malfunction of the
camera, but is due to principles related to Sense Up.
●
If the shutter speed is set to 1/50 to 1/10000, you can set the Sense Up to
"OFF" only.
●
Sense Up causes the frame rate of video recorded to the SD card to drop;
therefore, the playback speed of recorded video may vary.
Priority Sets the priority of ALC (function for maintaining the video level according to
the object brightness).
Combo : Selects the best combination automatically.
Motion : Assigns priority to AGC (automatic gain control). This is suitable
for shooting fast-moving objects.
Quality : Assigns priority to the Sense Up function. This is suitable for
shooting objects requiring a high picture quality.
