Exposure time
(
ExposureTime
): Defines the exposure time when set in the Camera. This command
is available in the CommCam “Acquisition Control” section :
Read function (ASCII): “
r tint
”;
Returned by the camera : Integer from 15 to 65535 (=1,5µs to 6553,5µs by step of 0,1µs)
Write function (ASCII): “
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 (ASCII): “
r tper
”;
Returned by the camera : Integer from 1 to 65536 (=0.1µs to 6553.6µs by step o 100ns)
Write function (ASCII): “
w tper
” <value> ;
The line period is active only in modes Sync 0 and Sync 5. It’s also disabled if in Free Run (Sync
0), 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.
