ICX252AKF
Diagonal 8.933mm (Type 1/1.8) Frame Readout CCD Image Sensor with Square Pixel for Color Cameras
Description
The ICX252AKF is a diagonal 8.933mm (Type 1/1.8)
interline CCD solid-state image sensor with a square
pixel array and 3.24M effective pixels. Frame readout
allows all pixels' signals to be output independently
within approximately 1/4.28 second. Also, number of
vertical pixels decimation allows output of 30 frames
per second in high frame rate readout mode. Ye, Cy,
Mg, G complementary color mosaic filters are used as
the color filters, and at the same time high sensitivity
and low dark current are achieved through the
adoption of Super HAD CCD technology.
This chip is suitable for applications such as
electronic still cameras, etc.

Measurement conditions
1) In the following measurements, the device drive conditions are at the typical values of the bias and clock
voltage conditions, and the frame readout mode is used.
2) In the following measurements, spot blemishes are excluded and, unless otherwise specified, the optical
black level (OB) is used as the reference for the signal output, which is taken as the value of the G/Ye
channel signal output or the Mg/Cy channel signal output of the measurement system.

These signals are processed to form the Y signal and chroma (color difference) signal as follows.
The approximation:
Y = {G + Mg + Ye + Cy}
1/4
= 1/4 {2B + 3G + 2R}
is used for the Y signal, and the approximation:
R Y = {(Mg + Ye) (G + Cy)}
= {2R G}
B Y = {(Mg + Cy) (G + Ye)}
= {2B G}
are used for the chroma (color difference) signal.

Note) Blacked out portions in the diagram indicate pixels which are not read out.
1. Frame readout mode
In this mode, all pixel signals are divided into two fields and output.
All pixel signals are read out independently, making this mode suitable for high resolution image capturing.
2. High frame rate readout mode
Output is performed at 30 frames per second by reading out 4 pixels for every 12 vertical pixels and adding
2 pixels in the horizontal CCD.
The number of output lines is 258 lines.
This readout mode emphasizes processing speed over vertical resolution.

the top and bottom of the picture in high frame rate readout mode. AF1 allows 1/60s and 1/50s output, and
AF2 allows 1/120s and 1/100s output, so these modes are effective for raising the auto focus (AF) speed.
In addition, the cut-out can begin from an optional line by controlling the number of frame shift lines that sweep
the top of the picture. The relation between the number of frame shift lines, the output start position and
number of output lines is shown in the table below.

Output line is Up to 258 lines.
The i + 1 and i + 2 line signals may be disrupted by elimination of the picture top, so these lines should not
be used.
For example, if the picture top is eliminated with i = 100 in AF1 mode (NTSC), lines 103 to 208 in high frame
rate readout mode are output from 26H of the timing chart.
If the picture top is eliminated with i = 160 in AF1 mode (NTSC), lines 163 to 258 in high frame rate readout
mode are output from 26H of the timing chart.

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
G

Mg
+ V
Ye

Cy
)/4
S = V
[mV]
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.
R

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.
Sm = 20

5. 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 G/Mg/Ye/Cy channel signal output is 150mV. Then measure the maximum
(Vmax [mV]) and minimum (Vmin [mV]) values of the G/Mg/Ye/Cy channel signal output and substitute the
values into the following formula.
SH = (Vmax Vmin) /150
100 [%]
6. Dark signal
Measure the average value of the signal output (Vdt [mV]) with the device ambient temperature 60C and
the device in the light-obstructed state, using the horizontal idle transfer level as a reference.
7. Dark signal shading
After measuring 6, measure the maximum (Vdmax [mV]) and minimum (Vdmin [mV]) values of the dark
signal output and substitute the values into the following formula.
Vdt = Vdmax Vdmin [mV]
8. Lag
Adjust the G/Mg/Ye/Cy channel signal output generated by strobe light to 150mV. After setting the strobe
light so that it strobes with the following timing, measure the residual signal (Vlag). Substitute the value into
the following formula.
Lag = (Vlag/150)

Notes)
Substrate bias control
1. The saturation signal level decreases when exposure is performed using the mechanical shutter, so
control the substrate bias.
2. A saturation signal level equivalent to that for continuous exposure can be assured by connecting a 1.3k
grounding resistor to the CCD C
SUB
pin.
Drive timing precautions
1. Blooming occurs in modes (high frame rate readout, etc.) that do not use the mechanical shutter, so do
not ground the connected 1.3k
resistor.
2. tf is slow, so the internally generated voltage V
SUB
may not drop to a sufficiently low level if the substrate
bias control signal is not set to high level 40ms before entering the exposure period and the 1.3k
resistor
connected to the C
SUB
pin is not grounded.
3. The blooming signal generated during exposure in mechanical shutter mode is swept by providing one
field or more of idle transfer through vertical register high-speed sweep transfer from the time the
mechanical shutter closes until sensor readout is performed. However, note that the V
L
potential and the
SUB pin DC voltage sag at this time.

Notes on Handling
1) Static charge prevention
CCD image sensors are easily damaged by static discharge. Before handling be sure to take the following
protective measures.
a) Either handle bare handed or use non-chargeable gloves, clothes or material.
Also use conductive shoes.
b) When handling directly use an earth band.
c) Install a conductive mat on the floor or working table to prevent the generation of static electricity.
d) Ionized air is recommended for discharge when handling CCD image sensors.
e) For the shipment of mounted substrates, use boxes treated for the prevention of static charges.
2) Soldering
a) Make sure the package temperature does not exceed 80C.
b) Solder dipping in a mounting furnace causes damage to the glass and other defects. Use a ground 30W
soldering iron and solder each pin in less than 2 seconds. For repairs and remount, cool sufficiently.
c) To dismount an image sensor, do not use a solder suction equipment. When using an electric desoldering
tool, use a thermal controller of the zero-cross On/Off type and connect it to ground.
3) Dust and dirt protection
Image sensors are packed and delivered by taking care of protecting its glass plates from harmful dust and
dirt. Clean glass plates with the following operations as required, and use them.
a) Perform all assembly operations in a clean room (class 1000 or less).
b) Do not either touch glass plates by hand or have any object come in contact with glass surfaces. Should
dirt stick to a glass surface, blow it off with an air blower. (For dirt stuck through static electricity ionized air
is recommended.)
c) Clean with a cotton bud and ethyl alcohol if grease stained. Be careful not to scratch the glass.
d) Keep in a case to protect from dust and dirt. To prevent dew condensation, preheat or precool when
moving to a room with great temperature differences.
e) When a protective tape is applied before shipping, just before use remove the tape applied for
electrostatic protection. Do not reuse the tape.
4) Installing (attaching)
a) Remain within the following limits when applying a static load to the package. Do not apply any load more
than 0.7mm inside the outer perimeter of the glass portion, and do not apply any load or impact to limited
portions. (This may cause cracks in the package.)
b) If a load is applied to the entire surface by a hard component, bending stress may be generated and the
package may fracture, etc., depending on the flatness of the bottom of the package. Therefore, for
installation, use either an elastic load, such as a spring plate, or an adhesive.

c) The adhesive may cause the marking on the rear surface to disappear, especially in case the regulated
voltage value is indicated on the rear surface. Therefore, the adhesive should not be applied to this area,
and indicated values should be transferred to other locations as a precaution.
d) The notch of the package is used for directional index, and that can not be used for reference of fixing.
In addition, the cover glass and seal resin may overlap with the notch of the package.
e) If the leads are bent repeatedly and metal, etc., clash or rub against the package, the dust may be
generated by the fragments of resin.
f) Acrylate anaerobic adhesives are generally used to attach CCD image sensors. In addition, cyano-
acrylate instantaneous adhesives are sometimes used jointly with acrylate anaerobic adhesives. (reference)
5) Others
a) Do not expose to strong light (sun rays) for long periods, as color filters will be discolored. When high
luminous objects are imaged with the exposure level controlled by the electronic iris, the luminance of the
image-plane may become excessive and discoloring of the color filter will possibly be accelerated. In such
a case, it is advisable that taking-lens with the automatic-iris and closing of the shutter during the power-
off mode should be properly arranged. For continuous using under cruel condition exceeding the normal
using condition, consult our company.
b) Exposure to high temperature or humidity will affect the characteristics. Accordingly avoid storage or
usage in such conditions.
c) Brown stains may be seen on the bottom or side of the package. But this does not affect the CCD
characteristics.
