Changing the Camera Settings
long exp booster [on/off]
(cont.) When camera is in the "long exp" mode, this function
lets you to set the focus or color for subjects in poor
lighting conditions by allowing 4 FRM (frames)
accumulation and gain adjustment. In such situations,
set "booster" to on, set the focus and color, and then
turn it off. You can then shoot in the long exposure
mode.

sync/w.en [sync/w.en]
This function lets you change the output from the
RGB/SYNC
only enabled when the unit is in the "long exp" mode.
sync Outputs a composite sync signal. This is the
normal setting.
w.en Outputs a WEN (timing) pulse. Use this function
to synchronize a connected frame memory.
Notes
• When the camera is set to "long exp', AGC, CCD IRIS,
AUTO IRIS (located on remote control unit) cannot be
used. When in the "long exp" mode, use the GAIN in
"step" or "ISO" and set the IRIS to MANUAL.
• Set the G. sync to ON when using the RGB output.
• This function is enabled only when both "Flash" and
"Printer Trig." are set to off.
step Sets the shutter to one of the following eight speeds:
FL (flickerless), 1/125, 1/250, 1/500, 1/1000, 1/2000,
1/4000, or 1/10000. When using the DXC-950P with
60 Hz lighting power, setting the shutter to FL gives
you flickerless images even under fluorescent light.

c.scan Sets the shutter speed in units of 1 H (horizontal
scanning time; 64 µs). The shutter speed can be set
to anywhere between 1/625 – 310/625 H. The setting
is made in units of 1 H. This setting can be used to
reduce noise (horizontal patterns) when shooting a
computer screen. To find the most appropriate setting,
use the DATA UP/DOWN buttons to change the
setting while observing the noise on a monitoring
screen.
Shutter speed calculation
Example: Shutter speed in 250/625 (H)
250 × 64 µs (1 H) + 35.6 µs (constant) = 16035.6 µs =
about 0.016 seconds
CCD-IRIS When an excessive amount of light passes through
the lens, this function increases the shutter speed to
cut exposure to the equivalent of up to 6 aperture
stops. The function is useful for microscope
applications where lighting that is just right for the
human eye often is too bright for the video camera.
When CCD-IRIS is set to ON, the excessive incident
light is automatically decreased to an appropriate level
for the video camera. The CCD iris function is also
useful for cutting out excess incident light that is not
cut out by the auto-iris lens in scenes containing very
bright patches (such as snow, or sea water reflecting
sunlight).
You can use CCD-IRIS in combination with AGC, and/
or auto-iris control.
