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 = 1.4mm) as an IR cut filter and
image at F5.6. 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 = 1.4mm) 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 Y signal (Ys) at the center of the screen and substitute the value into the following
formula.
S = Ys
×
[mV]
2. Saturation signal
Set to standard imaging condition
II
. After adjusting the luminous intensity to 10 times the intensity with
average value of the Y signal output, 200mV, measure the minimum value of the Y signal.
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 the 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 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 Y signal output is 200mV. Then measure the maximum (Ymax [mV]) and
minimum (Ymin [mV]) values of the Y signal and substitute the values into the following formula.
SHy = (Ymax – Ymin)/200

100 [%]
5. Uniformity between video signal channels
Set to standard imaging condition
II
. Adjust the luminous intensity so that the average value of the Y signal
output is 200mV, and then measure the maximum (Crmax, Cbmax [mV]) and minimum (Crmin, Cbmin
[mV]) values of the R – Y and B – Y channels of the chroma signal and substitute the values into the
following formula.
Sr = | (Crmax – Crmin)/200 |
×
100 [%]
Sb = | (Cbmax – Cbmin)/200 |
×
100 [%]
6. Dark signal
Measure the average value of the Y signal output (Ydt [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.
