Window Scan
The CV-A20CL/CV-A80CL permits "Windowing" in the vertical direction. This reduces the number
of lines being read out, thus increasing the frame rate. For the CV-A20CL the increment is 1 line
and for the CV-A80CL the increment is 2 lines. Depending on the number of lines selected the
frame rate can be varied from 60 fps for full line read out to 1125 fps.
Minimum read out line: 1 line for CV-A20CL, 2 lines for CV-A80CL
