5-3 Setting the Electronic Shutter
5-3 Setting the
Electronic Shutter
This section describes the shutter modes that can be used
with the electronic shutter of the camcorder, and describes
the procedure for selecting the shutter speed and shutter
mode.
5-3-1 Shutter Modes
The shutter modes that can be used with the electronic
shutter and the shutter speeds that can be selected are listed
below.
Selectable shutter modes and shutter speeds
1) The SLS mode can only be selected when the CCD scan mode(see page
100) is set to “I (interlace scan)”.
Notes
• Whatever the operating mode of the electronic shutter,
the sensitivity of the CCD decreases with increasing
shutter speed.
• When the automatic iris is used, the iris opens wider as
the shutter speed increases, thus reducing the depth of
field.
• In SLS (slow speed shutter) mode, the iris is fixed in the
fully-open position.
• Under artificial light, particularly fluorescent or mercury
lamps, the light intensity may appear to be constant, but
the red, green, and blue intensities are actually changing
in synchronization with the frequency of the power
supply causing flicker. Using an electronic shutter under
such lighting could make the flicker even worse. Color
flicker is particularly likely to happen when the power
supply frequency is 60 Hz (with the PDW-510/530) or
50 Hz (with the PDW-510P/530P). However, if the
power frequency is 50 Hz (with the PDW-510/530) or 60
Hz (with the PDW-510P/530P), setting the shutter speed
to 1/100 or 1/60 can reduce this flicker.
• When a bright object is shot in EVS mode or ECS mode
in such a manner that it fills the screen, the upper edge of
the picture may have poor quality because of an inherent
characteristic of CCDs. Before using EVS mode or ECS
mode, check the shooting conditions.
You can turn on or off the EVS mode on the SW STATUS
page of the PAINT menu.
5-3-2 Selecting the Shutter Mode
and Shutter Speed
Use the SHUTTER selector to select a shutter mode or a
standard-mode shutter speed. To set the shutter speed in
ECS or SLS mode, with the SHUTTER selector set to ON
and the ECS or SLS mode selected, use the MENU knob
for adjustment.
You can use the SHT ENABLE page of the OPERATION
menu to narrow the range of choice in advance, or to select
in advance whether or not you use ECS/SLS.
Setting the shutter mode and standard-
mode shutter speed
Once the shutter speed is selected, it is retained even when
the camcorder power is turned off.
1
Follow the procedure described in 6-2-2 “Selecting the
Display Items” (page 85) to set the VF DISPLAY
MODE item to “2” or “3” on the VF DISP 1 page of
the USER menu.
2
Push the SHUTTER selector from ON to SELECT.
Shutter
mode Shutter speed Application
Standard PDW-510/530: 1/100,
1/125, 1/250, 1/500,
1/1000, 1/2000 (sec.)

moving subjects with
little blurring.

(Extended
Clear Scan) PDW-510/530: 60.0 to
6000 Hz
PDW-510P/530P: 50.0
to 6000 Hz For obtaining images
with no horizontal
bands of noise when
shooting subjects
such as monitor
screens.
