5.4.2.1
Frame rate calculation if AOI is set
The calculation method for the frame rate in AOI mode depends on the setting
conditions of offset, height, bit allocation and binning control.
It also depends on the position of the readout such as the upper TAP, lower TAP and
covering both TAPs.

5.4.2.2 2 tap output
5.4.2.2a Binning OFF
If the bit allocation is set to 8-, 10- or 12-bit and the binning control is OFF or 2x1
1) For a centered readout which covers both the upper and lower TAPS
Use the following two formulas to calculate frame lines (A) and frame lines (B).
Use the larger number of frame lines for calculating the frame rate.
If they are the same number of lines, either one can be used.
Frame lines (A) = Roundup ((1)/4) +(540 –Offset) +10
Frame lines (B) = Roundup{[1081-(Height)]/4} + [( Height)-540] +10
Frame rate (Hz) = 1/ (Frame lines number x 0.00002825)
2) If the readout is only in the upper TAP
In this case, Offset < 540 and ( Height) ≤540
Roundup{( 1 )/4} +Roundup [540-( height)]/4} + 10
= Frame lines number
Frame rate (Hz)= 1/(Frame lines number x 0.00002825)
3) If the readout is only in the lower TAP
In this case, Offset > 540
Roundup[(1080-( Height))/4]
｝
+ Roundup[(Offset -540)/4] + 10 =
Frame lines number
Frame rate (Hz) = 1/(Frame lines number x 0.00002825)
