Remarks
Note
1) In accordance with the given electrooptical characteristics, the black level is defined as the average value
of D2, D3 to D12.
2) For the sensitivity test light is applied with a uniform intensity of illumination.
3) PRNU is defined as indicated below. Ray incidence conditions are the same as for Note 2.

Where the 5363 pixels are divided into blocks of 114 (Last block is 119 pixel). The maximum output of
each block is set to V
MAX
, the minimum output to V
MIN
and the average output to V
AVE
.
4) Use below the minimum value of the saturation output voltage.
5) Saturation exposure is defined as follows.

When the optical signal accumulated time is shorter, the dynamic range gets wider because the optical
signal accumulated time is in proportion to the dark voltage.
