Image Acquisition Control AW00089316000
124 Basler ace GigE
Determining whether your camera is operating with overlapped or with non-overlapped acquisition
is not a matter of issuing a command or switching a setting on or off. Rather the way that you
operate the camera will determine whether the frame acquisitions are overlapped or not. If we
define the “frame period” as the time from the start of exposure for line one in the frame N
acquisition to the start of exposure for line one in frame N+1 acquisition, then:
 Exposure will not overlap when:
Frame Period > Exposure Time Abs Parameter Setting + Total Readout Time
 Exposure will overlap when:
Frame Period  Exposure Time Abs Parameter Setting + Total Readout Time
Overlapped frame acquisition cannot be performed when the camera is set for
global reset release rolling shutter mode. Overlapped frame acquisition can only
performed when the camera is in the electronic rolling shutter mode.
