□
Set the start position to 2 x n and the number of valid lines to 4 x n based on 0 (maximum is fixed at 962).
However, the vertical start po number of effective lines <= 962 must be satisfied.
□
Total number of frames for several hours
Normal shutter mode
= Number of V blanking lines (27H) + Number of valid lines
Fixed trigger shutter mode
= Exposure time + Number of V blanking lines (53.5H) + Number of effective lines
□
Frame Rate
=
1 / (Total lines x Time for 1 line)
Time for 1 line = 18.69us (Normal shutter mode) / 22.22us (Fixed trigger shutter mode)

The frame rate of the fixed shutter trigger mode varies depending on the input trigger signal.
This is an example of the MAX frame rate that can be set.
