The line period is active only in Free Run modes. It’s also disabled if in this mode, the Integration time is set higher
than the Line Period.
The Tables of the minimum Line Period (Max Line Rate) versus the Data rate and the output
mode chosen are given in Appendix C of this document.
Trigger Too Slow
: Defines the Time limit (in ms) for the Camera to consider that the Incoming trigger is
too slow
.
This command is available in the CommCam “Acquisition Control” section :
Read function : “
r tgts
”;
Returned by the camera : Integer from 1 to 5368 (1 to 5368 milliseconds by step of 1ms)
Write function : “
w tgts
” <value> ;
Trigger too Slow
By default, the trigger is considered too slow after 1000ms of missing Incoming Trigger.
This limit can be tuned now by the User. This tuning is particularly important when the
camera is in
4S
with the
Exposure control active
and the Control Exposure mode set in “
4S
Only
” : In this mode the incoming Line Period is delayed from one line to be reproduced in
the camera after an exact measurement of the Line Period. If the trigger stops for a period
of time below the limit, this will considered as a “long time Line” and not a stop : Then the
next line will be delayed from the same value with the risk to loose new incoming triggers.
The Trigger too Slow limit has to be set at a value which is considered in the Application as
the minimum value for a real stop in the incoming trigger.
Full Exposure Control Mode
:
set the behaviour of the Full Exposure Control Mode when active . This
value is available in the CommCam “Image Format Control” section :
Read function : “
r stbm
”;
Return by the Camera : Integer from 0 to 2
Write Function : “
w stbm
<value>”
“0” : Mode 4S/2S With all Lines at the Switch
“1” :
Mode 4S/2S Without incorrect Lines at the Switch
“2” :
4S Only
This parameter is not available if the Sensor Mode is not 4S.
In addition, it has no effect if the Synchronization mode is not in Exposure Controlled (in 4S)
