Image Sensor Characteristics Measurement Method

Measurement conditions

(1) In the following measurements, each supply voltage is at the typical values.

(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 of Y signal

output of the measurement system.

Definition of Standard Imaging Conditions

1) Standard imaging condition I: Use a pattern box (luminance 706cd/m2, color temperature of 3200K halogen

source) as a subject. (Pattern for evaluation is not applicable.) Use a ND2 filter and image at F5.6 or

equivalent. 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 with a uniformity of brightness within 2% at all angles

(color temperature of 3200K).

1. Sensitivity

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

1/250s, measure the Y signal (Ys) at the center of the screen and substitute the values into the following

formula.

S = Ys ×

250

60

[mV]

2. Saturation signal

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

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

3. Smear

Set to standard imaging condition II. With using ND2 filter and the lens diaphragm at F5.6 or equivalent,

adjust the luminous intensity to 500 times the intensity applying with an average value of Y signal output,

200mV. 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 YSm [mV] of the Y signal output, and substitute

the values into the following formula.

Sm = YSm × 1 × 1 × 100 [%] (1/10V method conversion value)

200 500 10

4. Dark signal

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

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

5. Dark signal shading

After measuring 4, measure the maximum (Ydmax [mV]) and minimum (Ydmin [mV]) values of the Y signal

output, and substitute the values into the following formula.

∆Ydt = Ydmax – Ydmin [mV]
