4.9.2 External Trigger Exposure Mode (Trigger Edge)
In external trigger exposure mode
(Trigger Edge)
, the exposure time is determined
by the setting made through serial communication. Each exposure starts with the
rising edge and the line period is determined by the time from rising edge to rising
edge of the trigger pulse. The range of programmable exposure time and the timing
chart of the exposure and the readout are shown below.
