Panasonic WV-CS570/G Mode D'emploi page 24

• ALC Mode with BLC OFF
In this mode, the picture is divided into 48 areas. If
there is a source of brightness that interferes with
the clarity of the picture in these masks, correspon-
ding areas mask the light to keep the clarity of the
picture.
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.
Note:
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.
(3) Shutter Speed (SHUTTER)
You can select a shutter speed from among 1/50
(OFF), AUTO, 1/120,
1/2 000, 1/4 000, and 1/10 000 seconds.
See page 44 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 45 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 page 45 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.
1/250, 1/500, 1/1 000,
(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 45 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 colour temperature is monitored
continuously and thereby white balance is set auto-
matically. The colour temperature range for the
proper 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 colour temperature is out of the range
of 2 700 - 6 000 K.
2. When the scene contains mostly high colour 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 colour temperature range of approx. 2 300 -
10 000 K.
See page 47 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 47 for the setting.
