*6: Measured without phosphor sheet
*7: Integration time ts=1 ms
*8: Measured with a 2856 K tungsten lamp
*9: When the photodiode array is exposed to uniform light which is 50% of the saturation exposure, the photo response non-uiniformity
(PRNU) is defined as follows:
PRNU = ΔX/X × 100 [%]
X: average output of all elements, ΔX: difference between X and the maximum or minimum output, whichever is larger.
*10: Measured with a video data rate of 50 kHz and ts=1 ms in dark state
*11: Video output is negative-going output with respect to the output offset voltage.
