?10 ICX055AK 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. 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 g mg cy ye g mg cy ye g mg cy ye g mg a1 a2 b hreg color coding diagram

?17 ICX055AK 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?. 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 a) operate in clean environments (around class 1000 is appropriate). 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) do not expose to strong light (sun rays) for long periods, color filters will be discolored. 5) exposure to high temperature or humidity will affect the characteristics. accordingly avoid storage or usage in such conditions. 6) ccd image sensors are precise optical equipment that should not be subject to mechanical shocks.
