Measurement conditions
1) In the following measurements, the device drive conditions are at the typical values of the bias and clock
voltage conditions.
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 Y signal output
or chroma signal output of the measurement system.
Color coding of this image sensor & Composition of luminance (Y) and chroma (color difference) signals
Cy Ye Cy Ye As shown in the left figure, fields are read out. The charge is
A1 mixed by pairs such as A1 and A2 in the A field. (pairs such
G Mg G Mg
as B in the B field)
B
Cy Ye Cy Ye As a result, the sequence of charges output as signals from
A2 the horizontal shift register (Hreg) is, for line A1, (G + Cy),
Mg G Mg G (Mg + Ye), (G + Cy), and (Mg + Ye).
Hreg
These signals are processed to form the Y signal and chroma (color difference) signal. The Y signal is formed
by adding adjacent signals, and the chroma signal is formed by subtracting adjacent signals. In other words,
the approximation:
Y = {(G + Cy) + (Mg + Ye)} × 1/2
= 1/2 {2B + 3G + 2R}
is used for the Y signal, and the approximation:
R – Y = {(Mg + Ye) – (G + Cy)}
= {2R – G}
is used for the chroma (color difference) signal. For line A2, the signals output from Hreg in sequence are
(Mg + Cy), (G + Ye), (Mg + Cy), (G + Ye).
The Y signal is formed from these signals as follows:
Y = {(G + Ye) + (Mg + Cy)} × 1/2
= 1/2 {2B + 3G + 2R}
This is balanced since it is formed in the same way as for line A1.
In a like manner, the chroma (color difference) signal is approximated as follows:
– (B – Y) = {(G + Ye) – (Mg + Cy)}
= – {2B – G}
In other words, the chroma signal can be retrieved according to the sequence of lines from R – Y and – (B – Y)
in alternation. This is also true for the B field.

substitute the value into the following formula.
2) Fcr, Fcb
Set to standard imaging condition II. Adjust the luminous intensity so that the average value of the Y signal
output is 200mV, insert an R or B filter, and then measure both the difference in the signal level between

Notes on Handling
2) Soldering
a) Make sure the package temperature does not exceed 80°C.
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.
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.
– 16 –
ICX409AK
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 the 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 lead bend repeatedly and the 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, color filters will be discolored. When high
luminance objects are imaged with the exposure level control by electronic-iris, the luminance of the
image-plane may become excessive and discolor 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) The brown stain may be seen on the bottom or side of the package. But this does not affect the CCD
characteristics.
d) This package has 2 kinds of internal structure. However, their package outline, optical size, and strength
are the same.
