11-3-6 TRIGGER OUTPUT
The camera provides a range of trigger output signals with W-VIEW Mode. It is possible to output a
pulse that shows the period where all lines in the top or bottom half area expose at the same time.
(1) Global exposure timing output
It shows the global exposure timing where all lines in the top or bottom half area expose at the
same time. In W-VIEW Mode, there are two kinds of global exposure timing output for the longer
and the shorter exposure time. This output can set either global exposure timing output for the
longer or shorter exposure time.
Note
•
There is no output signal when the exposure time for the both top and bottom half area is shorter
than the frame readout time.
(2) Programmable timing output
By using the programmable timing output, synchronizing external devices is simple. A system that
needs simple timing signal does not require a delay unit or pulse generator. It is possible to
program and output a pulse that has an optional pulse width and an optional delay time to Read
End (the end of readout timing), Vsync or Input trigger pulse. The setting range for delay time is 0
µs to 10 s, and the setting range for pulse width is 1 µs to 10 s.
The relation between the parameter which can be set with each reference signal, and an output
signal becomes below.
Reference signal
Output signal
Read End
Camera outputs a pulse after certain delay, from the end of sensor readout.
Also the pulse width can be set.
Vsync
Camera outputs a pulse after certain delay, from the beginning of readout.
Also the pulse width can be set.
Input trigger pulse
Camera outputs a pulse after certain delay from the Hsync which is internal
signal and whose interval time 9.744 36 µs. Also the pulse width can be set.
