Image on demand mode (IOD) with exposure timer and frame
duration timer
Bit group: e
Value: 3
This mode is also free-running (like
M=0
), but exposure time and frame duration
is set accordingly, using the parameters
E
and
F
. Furthermore, the start of the
exposure may optionally be synchronized to the rising edge of an externally
applied synchronization pulse. Use parameter
T
to select the synchronization
signal source. If any synchronization event takes place during exposure, the cur-
rent frame may be exposed abnormally.
