4.8.2 External Trigger Exposure Mode (Trigger Edge)
In external trigger exposure mode
(Trigger Edge)
, the exposure time is
determined by the setting for the line period parameter, each exposure starts
with the rising edge and the line period is determined by the time from rising
edge to rising edge of the internal control signal. The range of programmable
exposure time, the timing chart of the exposure and the readout are shown
below.
