5.1.6

Maximal Frame Rate

The maximal frame rate of the camera depends on the camera settings. The following factors
influence the maximal frame rate (see also Table 5.1):

•

The length of the exposure time: A shorter exposure time can lead to an increase in the
maximal frame rate.

•

ROI height: a smaller height ROI can lead to an increase in the maximal frame rate.

•

ROI width: a smaller width ROI can lead to an increase in the maximal frame rate, but only
in steps (see Fig. 5.1).

•

In pulse width controlled exposure mode the maximal frame rate is lower than normal as
the exposure start is only allowed after the read out of the previous frame.

The maximal frame rate of the camera can be determined by a frame rate calculator in the
support section of the Photonfocus web page www.photonfocus.com. The maximal frame rate
with the current camera settings can be read out by a camera register with pflib and it is also
displayed in the PFRemote tool.

To have a rough idea about the maximal allowed frame rate for a given setting it is important
to know the 3 possible frame timings that are described in the next sections.

In free-running mode only the Simultaneous Read out Timings occur.
