Image Sensor Characteristics Measurement Method
Measurement conditions
1) In the following measurements, the substrate voltage and the reset gate clock voltage are set to the values
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 (OB) level is used as the reference for the signal output, and the value measured at point [
∗
A] in the
drive circuit example is used.
Definition of standard imaging conditions
1) Standard imaging condition I:
Use a pattern box (luminance 706cd/m
2
, color temperature of 3200K halogen source) as a subject. (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 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, 350mV, measure the minimum value of the signal output.
