Note: The CLK pulse should be set from high to low just once when the st pulse is low. The internal shift register starts operating
at this timing.
The integration time is determined by the start pulse cycles. However, since the charge integration of each pixel is carried
out between the signal readout of that pixel and the next signal readout of the same pixel, the start time of charge
integration differs depending on each pixel. In addition, the next start pulse cannot be input until signal readout from all
pixels is completed.
