Continuous mode
The camera outputs images as fast as possible in a free running mode.
The gap between two images is only one line, thus the total frame duration
takes t
FDmin
. The exposure time is nearly equal to this inherent minimal frame
duration.
e
1
Image on demand mode (IOD)
The exposure is directly controlled by an externally applied signal.
Use parameter
T
to select the signal source. A rising edge at the
corresponding input starts exposure synchronized to the line after the next.
If the rising edge occurs during idle (the camera is not transmitting an
image), the exposure starts with a constant delay of two line durations.
The following falling edge stops exposure and starts output of the image
synchronized to the next line.
Due to the line jitter the next exposure should not start earlier than
t
FDmin
+ t
L
after the previous start of exposure.
