Acquisition Control Feature Descriptions
The following table describes these parameters along with their view attribute. Note that
when using the Sapera LT API to control a camera, most of these features (exception
made for AcquisitionArm and transferFrameSkip) are handled by Sapera LT’s
SapTransfer object).

Description

Acquisition Mode
AcquisitionMode
Set the acquisition mode of the device. It
defines the number of frames to capture during
an acquisition and the way the acquisition stops.
Beginner
Acquisition Start
AcquisitionStart
Start image capture using the currently selected
acquisition mode. The number of frames
captured is specified by AcquisitionMode
feature.
Beginner
Acquisition Arm
AcquisitionArm
Arms the device before an AcquisitionStart
command. This optional command validates all
the current features for consistency and
prepares the device for a fast start of the
acquisition. If not used explicitly, this command
is automatically executed at the first
AcquisitionStart but will not be repeated for
subsequent ones unless a data transfer related
feature is changed in the device.
Guru
Acquisition Status
AcquisitionStatus
Reads the state of the internal acquisition signal
selected using the Acquisition Status Selector
feature.
(i.e. False / True)
Expert
Acquisition Stop
AcquisitionStop
Stops the Acquisition of the device at the end of
the current frame unless the triggerFrameCount
feature is greater than 1.
Beginner
Acquisition
Frame
Count
AcquisitionFrameCount
Number of frames to be acquired in MultiFrame
acquisition mode.
Beginner
Frame Rate (in Hz)
AcquisitionFrameRate
Returns the camera internal frame rate.
Beginner
Frame Skip
transferFrameSkip
Sets the number of frames skipped for every
frame that is transferred. Skip n results in a
frame rate of 30.0/(n + 1).
Beginner
DFNC
Acquisition Status
AcquisitionStatus
Reads the state of the internal acquisition signal
selected using the Acquisition Status Selector
feature.
(i.e. False / True)
Expert
Acquisition Buffering
All acquisitions are internally buffered and transferred as fast as possible to the host
system. This internal buffer allows uninterrupted acquisitions no matter of any transfer
delays that might occur (such as acquisition frame rates faster that the Gigabit Ethernet
link or the
). Only when the internal buffer is consumed would an Image
Lost Event be generated (currently this is reported in the frame’s metadata only, see the
