Pseudo-exposure control mode (Edge)
In Pseudo-exposure control mode
(Edge)
, the exposure time is determined by
sending a camera command. Each exposure starts with the rising edge and the line
period is determined by the time from rising edge to rising edge of trigger pulse. The
range of programmable exposure time, the timing chart of the exposure and the
readout are shown below.
