*13: Dark output increases if the start pulse cycle or the start pulse high period is lengthened.
*14: The integration time equals the high period of ST plus 34 CLK cycles.
The shift register starts operation at the rising edge of CLK immediately after ST goes low.
The integration time can be changed by changing the ratio of the high and low periods of ST.
If the first Trig pulse after ST goes low is counted as the first pulse, the Video signal is acquired at the rising edge of the 50th Trig pulse.
