ICX204AK Diagonal 6mm (Type 1/3) Progressive Scan CCD Image Sensor with Square Pixel for Color Cameras Description The ICX204AK is a diagonal 6mm (Type 1/3) interline CCD solid-state image sensor with a square pixel array and 800K effective pixels. Progressive scan allows all pixels' signals to be output independently. Also, the adoption of high frame rate readout mode supports 60 frames per 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 applications such as electronic still cameras, PC input cameras, etc. Features • Progressive scan allows individual readout of the image signals from all pixels. • High horizontal and vertical resolution (both approx. 600TV-lines) still image without a mechanical shutter. • Supports high frame rate readout mode (effective 256 lines output, 15MHz drive: 45 frame/s, 20MHz drive: 60 frame/s) • Square pixel • Horizontal drive frequency: Typ.: 15MHz, Max.: 20MHz • No voltage adjustments (reset gate and substrate bias are not adjusted.) • R, G, B primary color mosaic filters on chip • High resolution, high color reproductivity, high sensitivity, low dark current • Low smear, excellent antiblooming characteristics • Continuous variable-speed shutter • Recommended range of exit pupil distance: –20 to –100mm Device Structure • Interline CCD image sensor • Image size: • Total number of pixels: • Number of effective pixels: • Number of active pixels: • Chip size: • Unit cell size: • Optical black: • Number of dummy bits: • Substrate material: 16 pin DIP (Plastic) AAAAA AAAAA AAAAA AAAAA AAAAA Pin 1 2 V 3 Pin 9 H 7 40 Optical black position (Top View) Diagonal 6mm (Type 1/3) 1077 (H) × 788 (V) approx. 850K pixels 1034 (H) × 779 (V) approx. 800K pixels 1024 (H) × 768 (V) approx. 790K pixels (diagonal 5.952mm) 5.80mm (H) × 4.92mm (V) 4.65µm (H) × 4.65µm (V) Horizontal (H) direction: Front 3 pixels, rear 40 pixels Vertical (V) direction: Front 7 pixels, rear 2 pixels Horizontal 29 Vertical 1 Silicon ∗ Wfine CCD is a registered trademark of Sony Corporation.

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. – 11 – ICX204AK Measurement conditions 1) In the following measurements, the device drive conditions are at the typical values of the progressive scan mode, 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 the Gr/Gb signal 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. (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. 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. 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 1/100s, measure the signal outputs (VGr, VGb, VR and VB) at the center of each Gr, Gb, R and B channel screen, and substitute the values into the following formulas. VG = (VGr + VGb)/2 Sg = VG × 100/30 [mV] Rr = VR/VG Rb = VB/VG 2. Saturation signal Set to standard imaging condition II. After adjusting the luminous intensity to 20 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, Ba), and then adjust the luminous intensity to 500 times the intensity with the 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 × 1 1 × × 100 [%] (1/10V method conversion value) 10 500 – 12 – ICX204AK 4. Video signal shading Set to standard imaging condition III. 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 [%] 5. Uniformity between video signal channels After measuring 4, measure the maximum (Rmax [mV]) and minimum (Rmin [mV]) values of the R signal and the maximum (Bmax [mV]) and minimum (Bmin [mV]) values of the B signal, and substitute the values into the following formulas. ∆Srg = (Rmax – Rmin)/150 × 100 [%] ∆Sbg = (Bmax – Bmin)/150 × 100 [%] 6. Dark signal Measure the average value of the signal output (Vdt [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. 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. Line crawl Set to standard imaging condition II. Adjusting the luminous intensity so that the average value of the Gr signal output is 150mV, and then insert R, G and B filters and measure the difference between G signal lines (∆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. Lag Adjust the Gr signal output value 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.

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.) AAAA AAAA AAAA AAAA Cover glass 50N 50N Plastic package Compressive strength AAAA AAAA 1.2Nm Torsional strength 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. – 21 – ICX204AK 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. – 22 – – 23 – 1.2 2.5 0.69 ~ ~ Plastic GOLD PLATING 42 ALLOY 0.9g LEAD TREATMENT LEAD MATERIAL PACKAGE WEIGHT 0.3 M 1.27 9.2 10.3 12.2 ± 0.1 H PACKAGE MATERIAL V 6.1 ~ 2.5 0.46 0.3 A 1.2 2.5 8.4 (For the first pin only) 0.5 PACKAGE STRUCTURE B 5.7 D B' C 1 8 11.6 16 9 2.5 2-R0.5 9.
