Calculation of the maximum frame rate
The frame rate mainly depends on the exposure time and readout time. The frame rate is the
inverse of the frame time.
The maximal frame rate with current camera settings can be read out from the
property
FrameRateMax
.

Calculation of
the frame time (simultaneous mode)
The calculation of the frame time in simultaneous read out mode requires more detailed data
input and is skipped here for the purpose of clarity.

A frame rate calculator for calculating the maximum frame rate is available in
the support area of the Photonfocus website.
An overview of resulting frame rates in different exposure time settings is given in table Table
4.10 and Table 4.11.
