It is not enough to use "Setting -> Base -> Camera -> GenICam -> Acquisition Control ->
Acquisition Frame Rate" for this, as there are small fluctuations in this frame rate if the
exposure time changes. These fluctuations lead to oscillations (see settings marked with red
boxes in Figure 1). The "Acquisition Frame Rate" will only provide the exact frame rate if
auto exposure is turned off.
As shown in Figure 1, it is possible to set ("mv Exposure Auto Mode") which part of the camera
handles the auto expose (device or the sensor itself; pink boxes). Using "mvSensor" as "mv
Exposure Auto Mode", it is possible to avoid oscillations in some cases. The reason for this
behavior is that you can set more parameters like "mv Exposure Auto Delay Images" in contrast to
"mvDevice". However, as mentioned above it is recommended to use a timer based trigger when
using auto expose together with continuous acquisition.
