Chapter 3 Adjustments and Settings for Shooting
The shutter modes that can be used with the
electronic shutter and the shutter speeds that can
be selected are listed below.
Standard mode
Select this mode for shooting fast-moving
subjects with little blurring.
a) This speed cannot be selected when the unit is in Slow
& Quick Motion mode and FRAME RATE on the
REC FUNCTION page of the OPERATION menu is
set to a value that is greater than the system frequency.
ECS (Extended Clear Scan) mode
Select this mode for obtaining images with no
horizontal bands of noise when shooting subjects
such as monitor screens.
a) When the unit is in Slow & Quick Motion mode and
FRAME RATE on the REC FUNCTION page of the
OPERATION menu is set to a value that is greater
than the system frequency, the lower limits for shutter
speed settings are as shown below.
29.97P: 60.00Hz
25P: 50.00Hz
23.98P: 48.00Hz
SLS (slow speed shutter) mode
Select this mode for shooting subjects in low level
lighting conditions.
Notes
• SLS mode cannot be selected when SCAN
MODE is set to 23.9P.
• 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
