-15-

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 bright-
ness by masking the source of the strong bright-
ness, thereby the main object is displayed clearly.

Notes:

• The result of field setup of the mask area and level

adjustment is fed back (effected) to the lens iris con-
trol in the ALC mode.

• Select OFF for SUPER-D2 on the ALC CONT menu

when using only for the outdoors.
If ON is selected for the SUPER-D2 parameter, a
shadow (black line) may appear at the boundary
between the bright and the dim scenes. This is a
natural phenomenon and does not indicate trouble.

(3) Shutter Speed (SHUTTER)

You can select a shutter speed from among 1/60
(OFF), AUTO, 1/100, 1/250, 1/500, 1/1 000,
1/2 000, 1/4 000, and 1/10 000 seconds.
See page 36 for the setting.

(4) Gain Control (AGC)

You can set the gain of an image to automatic
adjustment [AGC ON (LOW, MID, HIGH)] or fixed
(AGC OFF).
See page 36 for the setting.

(5) Electronic Sensitivity Enhancement (SENS UP)

The electronic sensitivity enhancement function
varies the shutter speed to increase the sensitivity in
low light conditions.
You can select either of the following shutter speeds
for SENS UP.
1/25 seconds (x2), 1/12.5 seconds (x4), 1/8.3 sec-
onds (x6), 1/5 seconds (x10), 1/3.1 seconds (x16) or
1/1.6 seconds (x32).
See pages 36 for the setting.
There are two modes for SENS UP as follows:
AUTO: If you select x32, the sensitivity is increased

automatically up to x32.

FIX: If you select x32, the sensitivity is increased to

a fixed x32.

Notes:

• Moving objects will appear blurred when shot in the

electronic sensitivity enhancement mode since
SENS UP is equivalent to reducing the shutter
speed in a still picture camera.

• The horizontal and vertical resolution will be lowered

in this mode.

• If the iris opening is too small, the SENS UP/AUTO

mode will not function.

(6) Synchronization (SYNC)

You can select the internal sync (INT) mode or the
line-lock sync (LL) mode. Additionally, this model
accepts the VD2 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 the line-lock (LL) mode, you can
adjust vertical phase.
See page 37 for the setting.

Important Notices:

The priorities of sync modes are assigned as fol-
lows:

1. Multiplexed vertical drive (VD2) (highest)
2. Line-lock (LL)
3. Internal sync (INT) (lowest)

Note: The priorities of the automatic sync modes are

the same as the above.

(7) White Balance (WHITE BAL)

You can select either of three modes shown below
for white balance adjustment:

• Auto-Tracing White Balance (ATW1)

In this mode, the color temperature is monitored
continuously and thereby white balance is set auto-
matically. The color temperature range for the prop-
er white balance is between approx.
2 700 and 6 000 K. Proper white balance may not
be obtained under the following conditions:

1. When the color temperature is out of the range of

2 700 - 6 000 K.

2. When the scene contains mostly high color tem-

perature (bluish) objects, such as a blue sky.

3. When the scene is dim.

In these cases, select the AWC mode.

• Auto-Tracing White Balance (ATW2)

This mode enables the camera to trace the white
balance when it is used in an area lit by sodium
lamps.

• Automatic White Balance Control (AWC)

In this mode, accurate white balance is obtained
within a color temperature range of approx. 2 300 -
10 000 K.
See page 38 for the setting.

(8) Motion Detector (MOTION DET)

The motion detector detects motion in a scene by
monitoring changes in the brightness level. You can
select the sensitivity level for the motion on the setup
menu.
When the camera detects motion, it sends an alarm
signal to the external equipment and stops at its
position for the preset dwell time.
See page 39 for the setting.
