Basler racer Camera Link 72
Determining whether your camera is operating with overlapped or non-overlapped exposure and
readout 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 exposures and readouts are overlapped or not.
If we define the “line period” as the time from the start of exposure for one line acquisition to the
start of exposure for the next line acquisition, then:
 Exposure will not overlap when: Line Period > Exposure Time + Readout Time
 Exposure will overlap when: Line Period ≤ Exposure Time + Readout Time
You can determine the readout time by reading the value of the ReadoutTimeAbs parameter. The
parameter indicates what the readout time will be in microseconds given the camera’s current
settings. You can read the ReadoutTimeAbs parameter value from within your application software
by using the Basler pylon API. The following code snippet illustrates using the API to get the
parameter value:
double ReadoutTime = camera.ReadoutTimeAbs.GetValue();
You can also use the Basler pylon Viewer application to easily get the parameter value.
For more information about the pylon API and the pylon Viewer, see Section 3.1 on page 26.
You can also determine the readout time via direct register access by reading out the value of the
Readout Time Raw register.
