Gain
When “Auto” has been selected as the Charge Time setting, the setting is kept to “Auto” regard-
less of the Gain setting selected here.
Auto: The light quantity is adjusted automatically.
0 dB: Under normal circumstances, this setting is used.
1 dB to 30 dB: Use this setting while shooting dark scenes if it is not possible to achieve a sat-
isfactory video output even when the lens diaphragm is opened.
N/Eye L (Night Eye L): Use this setting if it is not possible to achieve a satisfactory video output
even at 30 dB.
N/Eye H (Night Eye H): Use this setting if it is not possible to achieve a satisfactory video output
even at the Night Eye L setting.
Digital Gain Up
(0dB, 6dB, 12dB, 18dB, 24dB, 30dB) This can be set when a setting other than “Auto” has been
selected as the Gain setting.
0 dB: Under normal circumstances, this setting is used.
6 dB to 30 dB: Use this setting while shooting dark scenes if it is not possible to achieve a sat-
isfactory video output even when the lens diaphragm is opened and “Night Eye” is selected as
the Gain setting.
AGC Max Gain
(6dB, 12dB, 18dB, 24dB, N/Eye L, N/Eye H) This is used to set the maximum gain up when
“Auto” has been selected as the Gain setting.
Charge Time
(Auto, OFF, 1/30s, 1/15s, 1/8s, 1/4s, 1/2s, 1s, 2s) This is used to set the CCD storage time.
OFF: Under normal circumstances, this setting is used.
Auto: ALC is performed followed by AGC and then by the data storage, and the camera automat-
ically adjusts the light quantity.
If the Shutter Mode setting is set to “ELC”, ELC is performed by ALC, AGC and then by the data
storage in this order, and the light quantity is automatically adjusted. The Shutter Mode setting
cannot be changed at this time.
1/30s to 2s: Use this setting if it is not possible to achieve a satisfactory video output even when
the gain up setting is used.
The electronic shutter goes “OFF” at this time, the Shutter Mode setting and Step/Synchro set-
ting cannot be changed.
*If the Field/Frame setting has been set to “Frame1” or ”Frame2”, 1/15s to 2s is selected as the
storage time setting, and the sensitivity is set to about one-half of that obtained with when the
Field/Frame setting has been set to “Field”.
