of the internal output satisfies with ABL larger than
1 000 times exposure of the standard exposure conditions,
and V

larger than 650 mV.
1. T
A
= +60 C
2. The average output voltage under uniform illumination.
The standard exposure conditions are defined as when
Vo is 150 mV.
3. The image area is divided into 10 x 10 segments under
the standard exposure conditions. Each segment's
voltage is the average output voltage of all pixels within
the segment. PRNU is defined by (Vmax – Vmin)/Vo,
where Vmax and Vmin are the maximum and minimum
values of each segment's voltage respectively.
4. The image area is divided into 10 x 10 segments. Each
segment's voltage is the average output voltage of all
pixels within the segment. V
SAT
is the minimum
segment's voltage under 10 times exposure of the
standard exposure conditions.
5. The average output voltage under non-exposure
conditions.
6. The image area is divided into 10 x 10 segments under
non-exposure conditions. DSNU is defined by (Vdmax –
Vdmin), where Vdmax and Vdmin are the maximum and
minimum values of each segment's voltage respectively.
7. The average output voltage when a 1 000 lux light
source with a 90% reflector is imaged by a lens of F4,
f50 mm.

8. The sensor is exposed only in the central area of V/10
square with a lens at F4, where V is the vertical image
size. SMR is defined by the ratio of the output voltage
detected during the vertical blanking period to the
maximum output voltage in the V/10 square.
9. The sensor is exposed at the exposure level
corresponding to the standard conditions. AI is defined
by the ratio of the output voltage measured at the 1st
field during the non-exposure period to the standard
output voltage.
10. The sensor is exposed only in the central area of V/10
square, where V is the vertical image size. ABL is
defined by the ratio of the exposure at the standard
conditions to the exposure at a point where blooming is
observed.
11. Observed with a vector scope when the color bar chart
is imaged under the standard exposure conditions.
12. The difference between the average output voltage of the
(Mg + Ye), (G + Cy) line and that of the (Mg + Cy), (G +
Ye) line under the standard exposure conditions.
13. The difference between the average output voltage of
the odd field and that of the even field under the
standard exposure conditions.
