3.8 Controlling the Camera’s Shutter and Strobe
The camera has a TTL compatible signal for controlling an external shutter or strobe light.
A connector and signal description is available in section 2.2.4 Shutter Control Connector.
Shutter Control
The
sct
command controls the signal that opens and closes the shutter.
To control the shutter timing, use the command:
Syntax:
sct f f
Syntax Elements:
f
Shutter opening time before exposure. The camera will be held in
charge reset during this time to allow the shutter to open prior to
exposure. Allowable range is
0
to
65
milliseconds in .001 millisecond
steps. The sensor requires that the charge reset is always a minimum
of .1ms for opening times of .1ms or less. If the opening time is set to
zero, the shutter control signal goes active at the start of the exposure
and does not include sensor’s .1ms charge reset time.
f
Shutter closing time after exposure. To prevent smearing, the camera
will wait the specified closing control time before starting readout.
Notes:
•
The sensor continues to collect charge while the shutter is closing
•
For short exposures, the shutter closing time should be included
when calculating the desired exposure time.
