NOTES :

• VOFD should be adjusted to the minimum voltage such

that ABL satisfy the specification, or to the value

displayed on the device.

1. TA = +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. VSAT 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.
