ICX085AK
Diagonal 11mm (Type 2/3) Progressive Scan CCD Image Sensor with Square Pixel for Color Cameras
Description
The ICX085AK is a diagonal 11mm (Type 2/3)
interline CCD solid-state image sensor with a square
pixel array. Progressive scan allows all pixels
signals to be output independently within
approximately 1/12 second. This chip features an
electronic shutter with variable charge-storage time
which makes it possible to realize full-frame still
image without a mechanical shutter. High resolution
and high color reproductivity are achieved through
the use of R, G, B primary color mosaic filters.
Further, high sensitivity and low dark current are
achieved through the adoption of HAD (Hole-
Accumulation Diode) sensors.
This chip is suitable for image input applications
such as still cameras which require high resolution.

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. G sensitivity, sensitivity comparison
Set to standard imaging condition I. After selecting the electronic shutter mode with a shutter speed of
1/80s, measure the signal outputs (VGr, VGb, VR and VB) at the center of each Gr, Gb, R and B channel
screens, and substitute the values into the following formula.
VG = (VGr + VGb)/2
Sg = VG ×
80
12
[mV]
Rr = VR/VG
Rb = VB/VG
2. Saturation signal
Set to standard imaging condition II. After adjusting the luminous intensity to 10 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 standard imaging condition II. 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 and Ba), and then adjust the luminous intensity to 500
times the intensity with 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.
Sm = VSm ÷
Gra + Gba + Ra + Ba

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 Gr signal output is 150mV. Then measure the maximum (Grmax [mV])
and minimum (Grmin [mV]) values of the Gr signal output and substitute the values into the following
formula.
SHg = (Grmax – Grmin)/150 × 100 [%]
