Monitor the pin 19 vertical ramp output and measure
the voltage at the 142nd line.
Monitor the pin 19 vertical ramp output and measure
the voltages at the 22nd line, the 142nd line, and the
262nd line. Let Va, Vb, and Vc be these
measurements, and calculate the following formula.
Vline8 = (Vb – Va)/(Vc – Va)
