2.3.2 Calculating the Frame Rate using Vertical Window
When camera frame rate changes with the size of the vertical window, the resulting
frame rate (FR) for each camera is shown on figure 2.10a – 2.10fg. The camera uses
an adaptive algorithm for the frame rate change, so it is difficult to put a simple
formula for the frame rate calculation. The camera will calculate and display the
actual frame rate at any vertical window selection.
