Calculating the Frame Rate using Vertical Window

The resulting frame rate (FR) for each camera can be approximately
calculated using formulas 2.1a – 2.1f, where WS is the window size. The
window size is the number of lines in the window (WS = 'End Line' – 'Start
Line' + 1). Figure 2.30 – 2.36 show a graphical representation of the formulas.

Horizontal and vertical windows can be enabled in all camera
modes.
The size of the horizontal window does not affect the frame rate.
The frame-grabber horizontal and vertical resolutions must be
adjusted for each window size.
a. The horizontal resolution is equal to the window size,
which is: 'End Pixel' - 'Start Pixel' + 1.
b. The vertical resolution is equal to the window siz
is: 'End Line' - 'Start Line' + 1
Positioning the horizontal window outside the image window
will result in an error.
Color version users – for proper color reconstruction 'Start pixel'
and 'Start Line' must be an odd number.
Vertical window feature is not available in IPX-2M30H-L
