Alvium G1 User Guide V1.1.1
ExposureMode = Timed
For all Alvium cameras, exposure time can be set by
ExposureTime
or
ExposureAuto
. For this,
ExposureMode
is set to
Timed
.
The selected exposure time is extended automatically:
• If the selected exposure time does not match the available increment, the
camera automatically extends the exposure time to the next increment.
• The
exposure time offset is included
in the selected exposure time.
ExposureMode = TriggerWidth or TriggerControlled
In addition, most global shutter (GS) cameras can control exposure time by the
trigger signal, with the
ExposureMode
set to
TriggerWidth
or
TriggerControlled
(using
ExposureStart
and
ExposureStop
).
The trigger controlled exposure time is extended automatically:
• If the trigger controlled exposure time does not match the available increment,
the camera automatically extends the exposure time to the next increment.
• Subsequently, the
exposure time offset is added
.
You can use
ExposureActive
to determine the duration of the exposure time
offset.
Operation for maximum frame rates
Values for maximum frame rates and for minimum and maximum exposure time in
the specification tables are based on following parameters:
• Factory settings (camera after startup)
• Minimum exposure time
• Full resolution
• Mono8 pixel format or 8-Bit Bayer pixel format
• Camera operation in freerun mode
• Minimum value for
SensorBitDepth
(8-bit sensor ADC readout mode if
available)
• Bandwidth required for the corresponding frame rate, as stated in the tables
for ROI frame rates.
Bandwidth
: Data is calculated for six steps in a range of 12 MBps and 122 MBps.
Bit depth
: Values are calculated for Mono8. If you are using color formats or 10-bit
or 12-bit pixel formats, frame rates fall below values for Mono8.
If
DeviceLinkThroughputLimit
is enabled, you can increase the
DeviceLinkThroughputLimit
value to increase maximum frame rates.
Triggering
: If cameras are triggered, frame rates are lower.
