Image Sensor Characteristics Measurement Method
Measurement conditions
1) In the following measurements, the substrate voltage and the reset gate clock voltage are set to the values
indicated on the device, and 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.

As shown in the left figure, fields are read out. The charge is
mixed by pairs such as A1 and A2 in the A field. (pairs such
as B in the B field)
As a result, the sequence of charges output as signals from
the horizontal shift register (Hreg) is, for line A1, (G + Cy),
(Mg + Ye), (G + Cy), and (Mg + Ye).
Hreg
Color Coding Diagram
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.

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 standard imaging condition I. After selecting the electronic shutter mode with a shutter speed of
1/250s, measure the Y signal (Ys) at the center of the screen and substitute the value into the following
formula.
S = Ys ×

2. Saturation signal
Set to standard imaging condition II. After adjusting the luminous intensity to 10 times the intensity with
average value of the Y signal output, 200mV, measure the minimum value of the Y signal.
3. Smear
Set to standard imaging condition II. With the lens diaphragm at F5.6 to F8, adjust the luminous intensity to
500 times the intensity with average value of the Y signal output, 200mV. When the readout clock is
stopped and the charge drain is executed by the electronic shutter at the respective H blankings, measure
the maximum value YSm [mV] of the Y signal output and substitute the value into the following formula.

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 Y signal output is 200mV. Then measure the maximum (Ymax [mV]) and
minimum (Ymin [mV]) values of the Y signal and substitute the values into the following formula.
SHy = (Ymax – Ymin)/200 × 100 [%]
5. Uniformity between video signal channels
Set to standard imaging condition II. Adjust the luminous intensity so that the average value of the Y signal
output is 200mV, and then measure the maximum (Crmax, Cbmax [mV]) and minimum (Crmin, Cbmin
[mV]) values of the R – Y and B – Y channels of the chroma signal and substitute the values into the
following formula.
∆Sr = | (Crmax – Crmin)/200 | × 100 [%]
∆Sb = | (Cbmax – Cbmin)/200 | × 100 [%]
6. Dark signal
Measure the average value of the Y signal output (Ydt [mV]) with the device ambient temperature 60°C and
the device in the light-obstructed state, using the horizontal idle transfer level as a reference.

ICX055BK
7. Dark signal shading
After measuring 6, measure the maximum (Ydmax [mV]) and minimum (Ydmin [mV]) values of the Y signal
output and substitute the values into the following formula.
∆Ydt = Ydmax – Ydmin [mV]
8. Flicker
1) Fy
Set to standard imaging condition II. Adjust the luminous intensity so that the average value of the Y signal
output is 200mV, and then measure the difference in the signal level between fields (∆Yf [mV]). Then
substitute the value into the following formula.
Fy = (∆Yf/200) × 100 [%]
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
fields of the chroma signal (∆Cr, ∆Cb) as well as the average value of the chroma signal output (CAr, CAb).
Substitute the values into the following formula.
Fci = (∆Ci/CAi) × 100 [%] (i = r, b)
9. Line crawls
Set to standard imaging condition II. Adjust the luminous intensity so that the average value of the Y signal
output is 200mV, and then insert a white subject and R, G, and B filters and measure the difference
between Y signal lines for the same field (∆Ylw, ∆Ylr, ∆Ylg, ∆Ylb [mV]). Substitute the values into the
following formula.
Lci = (∆Yli/200) × 100 [%] (i = w, r, g, b)
10. Lag
Adjust the Y signal output value generated by strobe light to 200mV. After setting the strobe light so that it
strobes with the following timing, measure the residual signal (Ylag). Substitute the value into the following
formula.
Lag = (Ylag/200) × 100 [%]

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 sensor.
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 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.
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 operation 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 the 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 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, cyanoacrylate 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.
