? 11 ? ICX428AKL image sensor characteristics measurement method measurement conditions 1) in the following measurements, the device drive conditions are at the typical values of the bias and clock voltage conditions. (when used with substrate bias external adjustment, set the substrate voltage to the value indicated on the device.) 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 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). 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. cy ye cy ye gmggmg cy ye cy ye mg g mg g b a1 a2 hreg color coding diagram

? 19 ? ICX428AKL 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 ceramic portions. therefore, for installation, use either an elastic load, such as a spring plate, or an adhesive. 39n lower ceramic upper ceramic compressive strength low melting point glass 29n shearing strength 29n tensile strength 0.9nm torsional strength
? 20 ? ICX428AKL 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 upper and lower ceramic are joined by low melting point glass. therefore, care should be taken not to perform the following actions as this may cause cracks. applying repeated bending stress to the outer leads. heating the outer leads for an extended period with a soldering iron. rapidly cooling or heating the package. applying any load or impact to a limited portion of the low melting point glass using tweezers or other sharp tools. prying at the upper or lower ceramic using the low melting point glass as a fulcrum. note that the same cautions also apply when removing soldered products from boards. e) 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.
