DescriptionThe ICX204AK is a diagonal 6mm (Type 1/3)
interline CCD solid-state image sensor with a squarepixel array and 800K effective pixels. Progressivescan allows all pixels' signals to be outputindependently. Also, the adoption of high frame ratereadout mode supports 60 frames per second. Thischip features an electronic shutter with variablecharge-storage time which makes it possible torealize full-frame still image without a mechanicalshutter. High resolution and high color reproductivityare achieved through the use of R, G, B primary colormosaic filters. Further, high sensitivity and low darkcurrent are achieved through the adoption of HAD(Hole-Accumulation Diode) sensors.
This chip is suitable for applications such aselectronic still cameras, PC input cameras, etc.

Cross-point voltage for the Hφ1 rising side of the horizontal transfer clocks Hφ1 and Hφ2 waveforms is VCR.
The overlap period for twh and twl of horizontal transfer clocks Hφ1 and Hφ2 is two.
VRGLH is the maximum value and VRGLL is the minimum value of the coupling waveform during the period from
Point A in the above diagram until the rising edge of RG.
In addition, VRGL is the average value of VRGLH and VRGLL.
VRGL = (VRGLH + VRGLL)/2
Assuming VRGH is the minimum value during the interval twh, then:
VφRG = VRGH – VRGL.
Negative overshoot level during the falling edge of RG is VRGLm.

Progressive scan mode High frame rate readout mode
Note) Blacked out portions in the diagram indicate pixels which are not read out.
Output starts from the line 7 in high frame rate readout mode.
1. Progressive scan mode
In this mode, all pixel signals are output in non-interlace format in 1/20s.
The vertical resolution is approximately 600TV-lines and all pixel signals within the same exposure period
are read out simultaneously, making this mode suitable for high resolution image capturing.
2. High frame rate readout mode
All effective areas are scanned in approximately 1/60s by reading out one line for every three lines. The
vertical resolution is approximately 200TV-lines.
This readout mode emphasizes processing speed over vertical resolution.

Measurement conditions
1) In the following measurements, the device drive conditions are at the typical values of the progressive scanmode, bias and clock voltage conditions.
2) In the following measurements, spot blemishes are excluded and, unless otherwise specified, the opticalblack level (OB) is used as the reference for the signal output, which is taken as the value of the Gr/Gbsignal output or the R/B signal output of the measurement system.
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. (Patternfor evaluation is not applicable.) Use a testing standard lens with CM500S (t = 1.0mm) as an IR cut filterand image at F5.6. The luminous intensity to the sensor receiving surface at this point is defined as thestandard 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 adjustedto the value indicated in each testing item by the lens diaphragm.
3) Standard imaging condition III:Image a light source (color temperature of 3200K) with a uniformity of brightness within 2% at all angles.Use a testing standard lens (exit pupil distance –33mm) with CM500S (t = 1.0mm) as an IR cut filter. Theluminous intensity is adjusted to the value indicated in each testing item by the lens diaphragm.
1. G sensitivity, sensitivity comparisonSet to standard imaging condition I. After selecting the electronic shutter mode with a shutter speed of1/100s, measure the signal outputs (VGr, VGb, VR and VB) at the center of each Gr, Gb, R and B channelscreen, and substitute the values into the following formulas.
VG = (VGr + VGb)/2Sg = VG × 100/30 [mV]Rr = VR/VG
Rb = VB/VG
2. Saturation signalSet to standard imaging condition II. After adjusting the luminous intensity to 20 times the intensity with theaverage value of the Gr signal output, 150mV, measure the minimum values of the Gr, Gb, R and B signaloutputs.
3. SmearSet to standard imaging condition II. With the lens diaphragm at F5.6 to F8, first adjust the average value ofthe Gr signal output to 150mV. Measure the average values of the Gr signal output, Gb signal output, Rsignal output and B signal output (Gra, Gba, Ra, Ba), and then adjust the luminous intensity to 500 timesthe intensity with the average value of the Gr signal output, 150mV. After the readout clock is stopped andthe charge drain is executed by the electronic shutter at the respective H blankings, measure the maximumvalue (VSm [mV]) independent of the Gr, Gb, R and B signal outputs, and substitute the values into thefollowing formula.
Sm = Vsm ÷ × × × 100 [%] (1/10V method conversion value)1500

4. Video signal shadingSet to standard imaging condition III. With the lens diaphragm at F5.6 to F8, adjust the luminous intensityso that the average value of the Gr signal output is 150mV. Then measure the maximum (Grmax [mV]) andminimum (Grmin [mV]) values of the Gr signal output and substitute the values into the following formula.
SHg = (Grmax – Grmin)/150 × 100 [%]
5. Uniformity between video signal channelsAfter measuring 4, measure the maximum (Rmax [mV]) and minimum (Rmin [mV]) values of the R signaland the maximum (Bmax [mV]) and minimum (Bmin [mV]) values of the B signal, and substitute the valuesinto the following formulas.
∆Srg = (Rmax – Rmin)/150 × 100 [%]∆Sbg = (Bmax – Bmin)/150 × 100 [%]
6. Dark signalMeasure the average value of the signal output (Vdt [mV]) with the device ambient temperature 60°C andthe device in the light-obstructed state, using the horizontal idle transfer level as a reference.
7. Dark signal shadingAfter measuring 6, measure the maximum (Vdmax [mV]) and minimum (Vdmin [mV]) values of the darksignal output and substitute the values into the following formula.
∆Vdt = Vdmax – Vdmin [mV]
8. Line crawlSet to standard imaging condition II. Adjusting the luminous intensity so that the average value of the Grsignal output is 150mV, and then insert R, G and B filters and measure the difference between G signallines (∆Glr, ∆Glg, ∆Glb [mV]) as well as the average value of the G signal output (Gar, Gag, Gab).Substitute the values into the following formula.
Lci = ∆Gli/Gai × 100 [%] (i = r, g, b)
9. LagAdjust the Gr signal output value generated by strobe light to 150mV. After setting the strobe light so that itstrobes with the following timing, measure the residual signal (Vlag). Substitute the value into the followingformula.

Notes on Handling
1) Static charge preventionCCD image sensors are easily damaged by static discharge. Before handling be sure to take the followingprotective 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) Solderinga) 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 protectionImage sensors are packed and delivered by taking care of protecting its glass plates from harmful dust anddirt. 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 ionizedair 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 limitedportions. (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 thepackage may fracture, etc., depending on the flatness of the bottom of the package. Therefore, forinstallation, 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, 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.
