q The standard output voltage is defined as 150 mV by the

average output voltage under uniform illumination.

q The standard exposure level is defined when the average

output voltage is 150 mV under uniform illumination.

NOTES :

1 Ta : +WC

2 The image area is divided mto 10X 10 segments. Tk ~-

ment’s voltage is the average output voltage of all the

pixels within the segment. PRNU is defined by (Vmax –

Vmin)/Vo, where Vmax and Vmin are the maximum and

the minimum values of each segment’s voltage respec-

tively, when the average output voltage Vo is 150 mV.

3 The image area is divided into 10x 10 segments.

The saturation signal is defined as the minimum of each

segment’s voltage which is the average output voltage of

all the pixels within the segment, when the exposure level

is ~t as 10 times, compared to standard level.

4 The average output voltage under a non-e-re @lticm.

5 The image area is div!ded into 10x 10 segments. OSNU is

defined by (Vdmax – Vdmin) under the non-exposure con-

dition where Vdmax and Vdmin are the maximum and M

minimum values of each segment’s voltage, respective y,

that is the average output voltage over al I pixels in the

segment.

6. The average output voltage when a 1 COO Iux light source

attached with a 90% reflector is imaged by a lens of F4,

f50 mm.

7, The sensor is adjusted to position a V/l O square at the

center of image area Mere V is the vetilcal length of the

image area. SMR is defined by the ratio of the output

voltage detected during the vertical blanking pericxl to the

maximum of the pixel voltage in the V/l O square.

8, The sensor is ex~d at the exmsure level corresWnd-

ing to the standard condition preceding ncm-exposure con-

dition. Al is defined by the ratio between the output volt-

age measured at the 1st field during the non-exposure

period and the standard output voltage.

9 The sensor is adjusted to position a V/l O square at the

center of image area. ABL is the ratio between the ex-

Dsure at the standard condition and the exposure at a

mint where a blmming is observed.
