• Measurement conditions

(1) In the following measurements, the substrate voltage is set to the value indicated on the device, and the

device drive conditions are at the typical values of the progressive scan mode, bias and clock voltage condi-

tions.

(2) In the following measurements, spot blemishes are excluded and, unless otherwise specified, the optical

black level (OB) is used as the reference for the signal output, which is taken as the value measured at point

[*B] of the measurement system.

• Definition of standard imaging conditions

(1) Standard imaging condition I:

Use a pattern box (luminance: 706 cd/m2, color temperature of 3200K halogen source) as a subject. (Pattern

for evaluation is not applicable.) Use a testing standard lens with CM500S (t = 1.0 mm) as an IR cut filter and

image at F8. The luminous intensity to the sensor receiving surface at this point is defined as the standard

sensitivity testing luminous intensity.

(2) Standard imaging condition II:

This indicates the standard imaging condition I with the IR cut filter removed.

(3) Standard imaging condition III:

Image a light source (color temperature of 3200K) with a uniformity of brightness within 2% at all angles. Use

a testing standard lens with CM500S (t = 1.0 mm) as an IR cut filter. The luminous intensity is adjusted to the

value indicated in each testing item by the lens diaphragm.

1. Sensitivity 1

Set to standard imaging condition I. After selecting the electronic shutter mode with a shutter speed of

1/100 s, measure the signal output (VS1) at the center of the screen, and substitute the value into the following

formula.

S1 = VS1 ×

2. Sensitivity 2

Set to standard imaging condition II. After selecting the electronic shutter mode with a shutter speed of

1/500 s, measure the signal output (VS2) at the center of the screen, and substitute the value into the following

formula.

S2 = VS2 ×

3. Saturation signal

Set to standard imaging condition III. After adjusting the luminous intensity to 20 times the intensity with the

average value of the signal output, 200 mV, measure the minimum value of the signal output.

4. Smear

Set to standard imaging condition III. With the lens diaphragm at F5.6 to F8, first adjust the luminous intensity

to 500 times the intensity with the average value of signal output, 200 mV. Then after the readout clock is

stopped and the charge drain is executed by the electronic shutter at the respective H blankings, measure the

maximum value (Vsm [mV]) of the signal output and substitute the value into the following formula.

Sm = 20 × log
