Image Sensor Characteristics Measurement Method

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 bias and clock voltage conditions.

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 and the value measured at point [∗A] in the

measurement system is used.

3) In the following measurements, this image sensor is operated in 1/50s interlaced mode.

Definition of standard imaging conditions

(Pattern for evaluation is not applicable.) Use a testing standard lens with CM500S (t = 1.00mm) 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:

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 = 1.00mm) as an IR cut filter. The luminous intensity is

adjusted to the value indicated in each testing item by the lens diaphragm.

1. Sensitivity

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

1/250s, measure the signal output (Vs) at the center of the screen and substitute the value into the

following formula.

S = Vs

[mV]

2. Saturation signal

Set to standard imaging condition II. After adjusting the luminous intensity to 10 times the intensity with

average value of signal output, 120mV, measure the minimum value of the signal output.

3. Smear

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

500 times the intensity with average value of signal output, 120mV. When 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.

4. Video signal shading

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

so that the average value of the signal output is 120mV. Then measure the maximum (Vmax [mV]) and

minimum (Vmin [mV]) values of the signal output and substitute the values into the following formula.

SH = (Vmax – Vmin)/120

× 100 [%]

5. Dark signal

Measure the average value of the signal output (Vdt [mV]) with the device ambient temperature 60°C and

the device in the light-obstructed state, using the horizontal idle transfer level as a reference.
