4-2 Setting the Electronic Shutter

This section explains the different modes which can be
used for the electronic shutter, and gives the
procedures for setting the shutter mode and shutter
speed.

4-2-1 About the Shutter Modes

The different shutter modes which can be used with the
electronic shutter of the HDC-950/930 camera, and the
shutter speeds which may be selected, are as follows:
Shutter modes and speeds

Standard 1/100, 1/125, 1/250,
1/500, 1/1000, 1/2000

Clear Scan) Hz to 4300 Hz (HDC-
950) or 60.0 Hz to

1) The values in the table are those with 60I/59.94I. With
other formats, the available values are different. For other
formats, see page 4-27(E).
2) Continuously variable in the range from 0 to 100% only
with the HDC-950. Only EVS (100%) can be selected
with the HDC-930.
Notes
• Regardless of the shutter mode used, as the shutter
speed increases the iris opening will become wider,
and the depth of field will be reduced.
• With artificial lighting, particularly fluorescent lights
and mercury vapor lamps, the brightness appears to
be constant, but in fact the strength of the red, green,
and blue components varies at the power supply
frequency. This phenomenon is known as "flicker".
When using the electronic shutter under these lighting
conditions, there are certain cases in which the flicker
is more noticeable. In particular, color flicker is
evident when the power frequency is 60 Hz. In areas
where the power frequency is 50 Hz, setting the
1
shutter speed to / second will reduce the flicker.
