54Alvium USB Cameras User Guide V3.6.4
Specifications
Differences between sensors with global shutter (GS), rolling shutter (RS), and
global reset shutter (GRS) are explained in Shutter types affecting image readout
on page 220. Triggering behavior differs between cameras with global shutter (GS)
and rolling shutter (RS). See Triggering on page 206 for details.
Digital binning
Alvium USB cameras combine digital horizontal binning and digital vertical binning,
for integer values 1 to 8.
Achieved frame rates may not match specified values
• Some sensors have an exposure start jitter that may reduce maximum frame
rates.
• Your individual setup may cause delays in data transmission.
Bandwidth adjustments
Consider the bandwidth available for camera payload depends on your individual
hardware, the operating system, software and drivers, and your application. We
recommend you to adjust
DeviceLinkThroughputLimit and MaxTransferSize
to your requirements. See Host setup and bandwidth on page 221.
Interdependencies between ROI and ExposureTime values
Changing parameters for ROI can affect values for
ExposureTime, such as
minimum, maximum, and increments, but
ExposureTime itself as well. We
recommend you to set:
• ROI values
• DeviceLinkThroughputLimit
before you set values for ExposureTime.
See Value changes by feature interdependencies on page 216 for details.
MaxTransferSize can have an impact as well.
Alvium models ≥12 MP resolution
If digital horizontal and digital vertical binning are set to 1× and the digital vertical
binning value is increased, digital horizontal binning is automatically set to 2×.
