Exposure time
(
ExposureTime
): Defines the exposure time when set in the Camera. This command is available
in the CommCam “Acquisition Control” section :
Read function : “
r tint
”;
Returned by the camera : Integer from 15 to 65535 (=1,5µs to 6553,5µs by step o 0,1µs)
Write function : “
w tint
” <value> ;
This value of exposure time is taken in account only when the synchronisation mode is “free run” (0) or
“Ext Trig with Exposure time set” (1). Otherwise it’s ignored.
Due to the limitation of the timing pixel inside the sensor, the Exposure time has to be set by
taking in account the limitation detailed in the APPENDIX B of this document.
The
Minimum exposure time
which can be set is
1,5µs
•
Line Period
(
LinePeriod
) : Defines the Line Period of the Camera in Timed mode
.
This command is available in
the CommCam “Acquisition Control” section :
Read function : “
r tper
”;
Returned by the camera : Integer from 1 to 65536 (=0,1µs to 6553,6µs by step o 100ns)
Write function : “
w tper
” <value> ;
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 (Chap. 9.2) of this document.
