7.2.3 Frame rate calculation in the AOI mode
The frame rate in AOI mode depends on each setting of Offset, Height, Bit allocation
or Binning control. In the following formulas, the part labelled (
round down
) has its
decimal values rounded down.
7.2.3.1 Binning control
setting : off or 1x2
If Offset is less 4, Offset is regarded as 4.
start_area_num = ((OffsetY - 4)/4)
round down
) x 4
end_area_num = (((2471 – ( OffsetY -5))/4)
round down )
x 4
Frame line number
=
(start_area_num / 4) + (( 2471 – end_area_num) – start_ar 1) +
(end_area_num / 4) + 52
Frame rate (Hz)
= 1/ (Frame line number x 0.00003879 )

7.2.3.2 Binning control setting : 2x1 or 2x2
If Offset is less 4, Offset is regarded as 4.
start_area_num = (((OffsetY x 2) – 8)/4)
round down
) x 4
end_area_num = (((2471 – (Height x 2) + (OffsetY x 2) -9))/4)
round down )
x 4
Frame line number
=
(start_area_num / 4) + ((( 2471 – end_area_num) – start_ar 1)/2) +
(end_area_num / 4) + 26
Frame rate (Hz)
= 1/ (Frame line number x 0.000042125 )
