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.
About the shutter modes
The shutter modes that can be used with the electronic
shutter and the shutter speeds that can be selected are listed
below.
• 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.
• 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. However, if the power
frequency is 50 Hz, setting the shutter speed to
1/100 can
reduce this flicker.
• When a bright object is shot in 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 ECS mode, check
the shooting conditions.
• In SLS mode, CCD white dot noise becomes more
prominent as the number of frames increases.
For details, see “Phenomena Specific to CCD Image
Sensors” on page 161.
To select the shutter mode and shutter
speed
Use the SHUTTER switch to select a shutter mode or a
standard-mode shutter speed. To set the shutter speed in
ECS or SLS mode, with the SHUTTER switch set to ON
and the ECS or SLS mode selected, use the MENU knob
for adjustment.
To set the shutter mode and the standard-mode
shutter speed
Once the shutter speed is selected, it is retained even when
the camcorder is turned off.

Make sure that neither menu nor status display is
shown.

Push the SHUTTER switch from ON to SEL.
