ICX252AK
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 = 1.0mm) 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.
1. Sensitivity
Set to standard imaging condition
I
. After selecting the electronic shutter mode with a shutter speed of
1/100s, measure the signal outputs (V
G
, V
Mg
, V
Ye
and V
Cy
) at the center of each G, Mg, Ye and Cy channel
screen, and substitute the values into the following formulas.
V = (V

2. Sensitivity comparison
Set to standard imaging condition
II
. Adjust the luminous intensity so that the average value of the
G/Mg/Ye/Cy channel signal output is 150mV, and then measure the Mg signal output (S
Mg
[mV]) and G
signal output (S
G
[mV]), and the Ye signal output (S
Ye
[mV]) and Cy signal output (S
Cy
[mV]) at the center of
the screen. Substitute the values into the following formulas.

3. Saturation signal
Set to standard imaging condition
II
. After adjusting the luminous intensity to 10 times the intensity with the
average value of the G/Mg/Ye/Cy channel signal output, 150mV, measure the minimum values of the G,
Mg, Ye and Cy signal outputs.
4. Smear
Set to standard imaging condition
II
. With the lens diaphragm at F5.6 to F8, first adjust the luminous
intensity to 500 times the intensity with the average value of the G/Mg/Ye/Cy channel 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 G, Mg, Ye and Cy
signal outputs, and substitute the values into the following formula.
