Image Sensor Characteristics Measurement Method
1) In the following measurements, the substrate voltage is set to the value indicated on the device, and the
2) In the following measurements, spot blemishes are excluded and, unless otherwise specified, the optical
3) In the following measurements, this image sensor is operated in 1/60s interlaced mode.
1) Standard imaging condition
2) Standard imaging condition II :
1. Sensitivity
2. Saturation signal
3. Smear
4. Video signal shading
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
Set to standard imaging condition II. After adjusting the luminous intensity to 10 times the intensity with
average value of signal output, 150mV, measure the minimum value of the signal output.
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, 150mV. 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.
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 150mV. 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)/150
Sm =
Measurement conditions
device drive conditions are at the typical values of the bias and clock voltage conditions.
black (OB) level is used as the reference for the signal output and the value measured at point [ A] in the
measurement system is used.
Definition of standard imaging conditions
Use a pattern box (luminance 706cd/m
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.
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.
