Note 1) The photo response non-uniformity (PRNU) is defined by the following equation, where Xave is the average output voltage
of the 2048 valid pixels and ∆x is the absolute value of the difference between Xave and the voltage of the maximum (or
minimum) output pixel, when the surface of the photo-sites is illuminated with light having a uniform distribution over the
entire surface.

The incident light intensity shall be 50% of the standard saturation light intensity.
Note 2) The odd/even bit non-uniformity (O/E) is defined by the following equation, where Xave is the average output voltage of
the 2048 valid pixels and Xn is the output voltage of the ‘n’th pixel, when the surface of the photo-sites is illuminated with
light having a uniform distribution over the entire surface.

In other words, this is the value obtained by dividing the average of the output difference between the odd and even pixels
by the average output voltage of all the valid pixels. The incident light intensity shall be 50% of the standard saturation
light intensity.
Note 3) The Saturation output voltage (VSAT) is defined as the output voltage at the point when the linearity of the photoelectric
characteristics cannot be maintained as the incident light intensity is increased. (The light intensity of exposure at this
point is called the saturation exposure.)
Note 4) The dark signal output voltage (VDRK) is defined as the average output voltage of the 2048 pixels in the dark condition at
Ta=25˚C and Tint=10ms. Normally, the dark output voltage doubles for every 8 to 10˚C rise in Ta, and is proportional to
Tint.
The dark signal output non-uniformity (DSNU) is defined as the difference between the maximum output voltage among
all the valid pixels and VDRK in the dark condition at Ta=25˚C and Tint=10ms.

Note 5) The dynamic range is defined by the following equation.

Since the dark signal voltage is proportional to the accumulation time, the dynamic range becomes wider when the
accumulation time is shorter.
