Generally, when a light from the background is too strong such as a spotlight, all objects except the
main object in the picture are displayed darker because the lens iris is adjusted with respect to
strong brightness. This model ignores strong brightness by masking the source of the strong
brightness, thereby all objects are displayed clearly.
Note:
The result of field setup of the mask area and level adjustment is fed back (effected) to the lens
iris control in ALC mode.
(3) Shutter Speed (SHUTTER)
You can select the shutter speed from 1/50 (OFF), 1/120, 1/250, 1/500, 1/1 000, 1/2 000, 1/4 000, and
1/10 000 seconds.
Note:
See page 23 for the setting.
(4) Gain Control (AGC)
You can set the gain (brightness level portion of an image) to automatic adjustment (Automatic Gain
Control ON) or fixed (Automatic Gain Control OFF).
Note:
See page 23 for the setting.
(5) Electronic Sensitivity Enhancement (SENS UP)
The electronic sensitivity emhancement (SENS UP) function varies the shutter speed to raise the
sensitivity in low light conditions when OFF is selected for ALC.
You can select the shutter speed for SENS UP from the preset values as follows;
1/30 seconds (x2), 1/15 seconds (x4), 1/10 seconds (x6), 1/6 seconds (x10), 1/3.8 seconds (x16), or
1/1.9 seconds (x32).
There are two modes for SENS UP as follows;
AUTO:
If you select x32, for example, the sensitivity is raised automatically to x32 max.
FIX:
If you select x32, for example, the sensitivity is raised to just x32.
Notes:
• See page 23 for the setting.
• Moving objects will appear blurred when shot during the electronic sensitivity enhancement
mode since SENS UP is equivalent to setting the shutter speed to a slower speed in a still picture
camera.
• The horizontal and vertical resolution will be lowered in this mode.
• If the video output level is adjusted too low (the iris opening is too small), the Electronic
Sensitivity Enhancement (SENS UP)/AUTO mode will not function. Select ALC mode with SUPER-
D ON in this condition.
(6) Synchronization (SYNC)
You can select internal sync mode (INT) or line-lock sync (LL). Additionally, this model accepts the
VD2 signal (multiplexed vertical drive signal) with the composite video output signal from a specified
component. Whenever the VD2 signal is supplied to this camera, the camera automatically switches
to the VD2 sync mode.
When you select line-lock sync (LL), you can set vertical phase adjustment for composite sync mode
or horizontal and sub-carrier phase adjustments for the black burst mode.
Important Notice:
The priority of sync modes is as follows:
1. Multiplexed Vertical Drive (VD2) (Highest)
2. Line-lock (LL)
3. Internal Sync (INT) (Lowest)
Note:
The priority of automatic sync mode is the same as shown above. See page 24 for the setting.
