Timing Between External Trigger Signal and
Video Signal Output
Video Signal Output
When the Trigger Mode is set to 0, the timing will be as follows.
After the exposure time is set by the Shutter command (CSR F0F0081Ch), VD pulses will be generated inside the
camera.
Images will be isochronously output after the A period from the falling edge of the VD.
(The following figure shows an example where the frame rate is 7.5 fps for the DFW-SX910, and 15 fps for the
DFW-X710.)
