*3: Uniformity is defined under the condition that the device is uniformly illuminated by light which is 50 % of the saturation
exposure level as follows:
PRNU= DX/X 100 (%)
Where X is the average output of all pixels and DX is the difference from the maximum or minimum output and X.

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 storage time is determined by the start pulse intervals. However, since the charge storage 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 storage
differs depending on each pixel. In addition, the next start pulse cannot be input until signal readout from all pixels is
completed.
