Calculation of Exposure Time
Max. Exposure Time = 1/FrameRate
Minimum Exposure Time = 100usec
Frame Rate (@ external synchronisation)
For external synchronisation please apply a TTL signal to the Sync In and Sync
Out BNC adapter of the adapter cable (scope of delivery). External
synchronisation may be operated in level detection mode. Please see the
external synchronisation timing for more information about resulting frame rates
and exposure times.
Alternatively SyncIn can be applied directly between Pin 1 and Pin 3 on the
camera power (Pwr.) connector, Sync Out between Pin 4 and Pin 3. The
synchronisation output can be used to synchronise other devices as e.g.
additional cameras or external light flashes.
The External synchronisation frame rate range can reach any value
between 10 fps and maximum Frame Rate @ internal synchronisation.
Multi ROI
The camera has a multi ROI output mode with a maximum of 32 ROIs There are
named multiroi0 to multiroi31.
Enabling:
MultiROI feature is enabled with XML entry “multiroi_number”:
-
‘1’ means no multi ROI (only 1 ROI defined by XML entries “Width” / “OffsetX”
and “Height” / “OffsetY”).
-
‘N’ (1 < N <= 32) means N ROI activated.
X_size: When multi ROI is enabled (N > 1), all ROIs have the same width
parameters defined by XML entries
“Width” and “OffsetX”.
Y_size:
Every enabled ROI “
XX
” (1 <= XX <= “multiroi_number”) is defined by 2
XML entries:
- Multiroi
XX
_y_start: 1
st
line of the ROI XX.
- Multiroi
XX
_y_height: height of the ROI XX
Output frame: The resulting output frame is the concatenation of all activated
ROI. Its width is the same as all ROI and its height is the sum of all ROI height.
