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.
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.
