ICX282AKF
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.
1. Sensitivity
Set to the standard imaging condition I. After selecting the electronic shutter mode with a shutter
speed of 1/100s, measure the signal outputs (VG, VMg, VYe and VCy) at the center of each G, Mg, Ye and
Cy channel screen, and substitute the values into the following formulas.
V = (VG + VMg + VYe + VCy)/4
S = V × ¹⁰⁰ [mV]

2. Saturation comparison
Set to the 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 (SMg [mV]) and G signal
output (SG [mV]), and the Ye signal output (SYe [mV]) and Cy signal output (SCy [mV]) at the center of the
screen. Substitute the values into the following formulas.
RMgG = SMg/SG
RYeCy = SYe/SCy
3. Satutation signal
Set to standaed imageing condition II. After adjusting the luminous intensity to 10 times the intsnsity with the
avarage 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 the 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.
The smear for modes other than frame readout mode is calculated from the storage time and signal
addition method. As a result, 2× speed mode (2) is the same, 2× speed mode (1) is double, and 8× speed
mode is 4 times that for frame readout mode.
