6.3.2 No-Shutter mode with Internal Trigger
In this mode, the exposure and readout are activated by the trigger pulse generated internally.
As the accumulation control is done by the internal counter, the accumulation is not affected by
the trigger jitter.
In this mode, the accumulation period depends on the trigger interval. Accordingly, if trigger
interval becomes longer, the sensitivity is increased.
To use this mode:
Set function
Trigger mode, No-Shutter
TR=0
Trigger origin, Internal
TG=0
Line rate
LR=4602 to 1201920
(54.70 µs to 14.30 ms in 11.9 ns increments)
Optional functions when using this mode:
One-push auto line rate
AR=0
Auto line rate reference
AL=0 to 1023
One-push white balance
WB
Important Note
The “one-push auto line rate” function is not recommended for continuous web applications,
as the speed of motion needs to be adjustable in order to maintain the aspect ratio of the
image.
Only gain based one-push white balance functions (WB) are available with this mode.
