Dark output voltage is proportional to the integration time and so the shorter the integration time, the wider the dynamic range.
*11: Photoresponse nonuniformity (PRNU) is the output nonuniformity that occurs when the entire photosensitive area is uniformly
illuminated by light which is 50% of the saturation exposure level. PRNU is measured using 2490 pixels excluding 3 pixels each at
both ends, and is defined as follows:
PRNU= ΔX/X × 100 (%)
X: average output of all pixels, ΔX: difference between X and maximum output or minimum output
*12: Signal components of the preceding line data that still remain even after the data is read out in a saturation output state.
Image lag increases when the output exceeds the saturation output voltage.
