ICX432DQF
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 testing standard lens with CM500S (t = 1.0mm) 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 = 1.0mm) as an IR cut filter. The luminous intensity is adjusted
to the value indicated in each testing item by the lens diaphragm.
(3) Standard imaging condition III:
Image a light source (color temperature of 3200K) with a uniformity of brightness within 2% at all angles.
Use a testing standard lens (exit pupil distance –33mm) with CM500S (t = 1.0mm) as an IR cut filter. The
luminous intensity is adjusted to the value indicated in each testing item by the lens diaphragm.
1. G Sensitivity, sensitivity comparison
Set to the standard imaging condition I. After setting the electronic shutter mode with a shutter speed of
1/100s, measure the signal outputs (VGR, VGb, VR and VB) at the center of each Gr, Gb, R and B channel
screen, and substitute the values into the following formulas.
VG = (VGr + VGb)/2
Sg = VG ×

Rr = VR/VG
Rb = VB/VG
2. Saturation signal
Set to the standard imaging condition II. After adjusting the luminous intensity to 20 times the intensity with
the average value of the Gr signal output, 150mV, measure the minimum values of the Gr, Gb, R and B
signal outputs.
3. Smear
Set to the standard imaging condition III. With the lens diaphragm at F5.6 to F8, first adjust the average
value of the Gr signal output to 150mV. Measure the average values of the Gr signal output, Gb signal
output, R signal output and B signal output (Gra, Gba, Ra, Ba), and then adjust the luminous intensity to
500 times the intensity with the average value of the Gr signal output, 150mV.
After 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]) independent of the Gr, Gb, R and B
signal outputs, and substitute the values into the following formula.
