Use a light source with color temperature of 3,200K hallogen lamp and CM-500S for IR cut filter. The light source is adjusted in accordance with the average value of Y signals indicated in each item. COLOR FILTER ARRAY The color filter array of this image sensor is shown in the right figure. this complementary mosaic CFA is used with the operation of field integration mode, where all of the photosensors are read out during each video field. The signals from two vertically-adjacent photosensor lines, such as line couple A1 or A2 for field A are summed when the signal charges are transferred into the vertical transfer CCD column. The read out line pairing is shifted down by one line for field B. The sensor output signals through the horizontal register (H-CCD) at line A1 are [G+Cy], [MG+Ye], [G+CY], [Mg+Ye]. These signals are processed in order to compose Y and C signals. By adding the two adjacent signals at line A1, Y signal is formed as follows 1 1 Y = --- [ ( G + Cy ) + ( Mg + Ye ) ] = --- ( 2 B + 3 G + 2 R ) 2 2 C signal is composed by substracting the two adjacent signals at line A1 Cy G B Cy Mg Ye Mg Ye G Cy G Cy Mg Ye A1 Mg Ye G A2 H - CCD Figure 3. Color Filter Array 10 KC75118C 1/5 INCH CCD IMAGE SENSOR FOR NTSC CAMERA R – Y = [ ( Mg + Ye ) – ( G + Cy ) ] = ( 2 R – G ) Next, the signals through H-CCD at line A2 are [Mg+Cy], [G+Ye], [Mg+Cy], [G+Ye]. Simmilary, Y and C signals are composed at line A2 as follows 1 1 Y = --- [ ( G + Ye ) + ( Mg + Cy ) ] = --- ( 2 B + 3 G + 2 R ) 2 2 – ( B – Y ) = [ ( G + Ye ) – ( Mg + Cy ) ] = – ( 2 B – G ) Accordingly, Y signal is balanced in relation to scanning lines, and C signal takes the form of R-Y and -(B-Y) on alternate lines. It is same for B field. TEST METHODS 1. Measure the light intensities (L) when the averaged illuminance output value (Y) is the standard illuminance output value, 150mV (YA) and when half of 150mV (1/2 YA). 1 Y A – --- Y A 2 S = ------------------------------L YA – L 1 --- Y A 2 2. Adjust the light intensity to 10 times that of Y signal output average value (YA = 150mV) , then test Y signal minimum value (Y = YSAT). 3. Adjust the light intensity to 500 times that of Y signal output average value (YA = 150mV), then remove the readout clock and drain the signal in photosensors by the electronic shutter operation in all the respective horizontal blanking times with the other clocks unchanged. Measure the maximum illuminance output value (YSM). Y SM 1 1 SM = ----------- × ---------- × ------- × 100 ( % ) YA 500 10 4. Adjust the light intensity to 1,000 times of the value with which Y is YA, then inspect whether there is blooming phenomenon or not. 11 1/5 INCH CCD IMAGE SENSOR FOR NTSC CAMERA KC75118C 5. Measure the maximum and minimum illuminance output value (YMAX, YMIN) when the light intensity is adjusted to make Y to be YA. Y MAX – Y MIN U = ------------------------------------- × 100 ( % ) YA 6. Measure YD with the horizontal idling time transfer level as reference, when the device ambient temperature is 60 °C and all of the light sources are shielded. 7. Follow test method 6, measure the maximum (DMAX) and minimum illuminance output (DMIN). ∆ D = D MAX – D MIN 8. Adjust the light intensity of Y signal output value by strobe light to 150mV (YA), calculate by below formula with measuring the image lag signal which is qenerated by below timing diagram.

Adjust the light intensity of Y signal average value to 150mV (YA), calculate by below formula with measuring the signal differences (∆Yf [mV]) between fields. F Y = ( ∆ Y f ⁄ YA ) × 100 ( % ) 10. Adjust the light intensity to make Y = YA using red (R) and blue (B) optical filters respectively, measure the differences (∆CR, ∆CB) between the chroma signal values in even and odd fields and the averaged chroma signal values (CR, CB). ∆ Ci F C = --------- × 100 ( % ) i Ci , where i = R, B 11. Adjust the light intensity to make Y = YA using red (R) and blue (B) optical filters respectively, measure the minimum (CR,MIN and CB,MIN) and maximum (C R,MAX and C B,MAX) chroma signal values. C i, MAX – C i, MIN DS i = -------------------------------------------- × 100 ( % ) Yi , where i = R, B 12. Adjust the light intensity to make Y = 150mV(YL) using white (no filter, W), red (R), green (G) and blue (B) optical filters respectively, measure the illuminance signal difference values (∆YLW, ∆YLR, ∆YLG, ∆YLB) between illuminance signal lines of the same field. ∆ YL L c = ------------i × 100 ( % ) i YL , where i = W, R, G, B 13 1/5 INCH CCD IMAGE SENSOR FOR NTSC CAMERA KC75118C SPECTRAL RESPONSE CHARACTERISTICS Excluding Light Source Characteristics 1 0.9 0.8 Spra R l R RESPONSE SpNORMALIZEDesponse (nsec) ectecltraesponse Cyan 0.7 Green 0.6 0.5 0.4 0.3 0.2 0.1 0 400 450 500 550 WAVE LENGTH(nm) Wave Length (nm) Figure 4.

Package Dimensions 19 1/5 INCH CCD IMAGE SENSOR FOR NTSC CAMERA KC75118C HANDLING INSTRUCTIONS • Static Charge Prevention CCD image sensors can be easily damaged by static discharge. Before handling, be sure to take the following protective measures. — Use non chargeable gloves, clothes or material. Also use conductive shoes. — When handling directly, use an earth band. — Install a conductive mat on the floor or working table to prevent generation of static electricity. — Ionized air is recommended for discharging when handling CCD image sensor. — For the shipment of mounted substrates, use boxes treated for the prevention of static charges. • Soldering — Make sure the package temperature does not exceed 80 °C. — Solder dipping in a mounting furnace causes damage to the glass and other defects. Use a grounded 30W soldering iron and solder each pin in less than 2 seconds. For repairs and and remount, cool sufficiently. — To dismount an imaging device, do not use a solder suction equipment. When using an electronic disoldering tool, use a thermal controller of the zero cross on/off type and connect to ground • Dust and Dirt Protection — Operate in the clean environments (around class 1000 will be appropriate). — Do not either touch glass plates by hand or have object come in contact with glass surface. Should dirt stick to a glass surface blow it off with an air blow (for dirt stuck through static electricity ionized air is recommended). — Clean with a cotton bud and ethyl alcohol if the glass surface is grease stained. Be caerful not to scratch the glass. — Keep in case to protect from dust and dirt. To prevent dew condensation, preheat or precool when moving to a room with great temperature differences. — When a protective tape is applied before shipping, just before use remove the tape applied electrostatic protection. Do not reuse the tape. • Do not expose to strong light (sun rays) for long period, color filter are discolored. • Exposure to high temperature or humidity will affect the characteristics. accordingly avoid storage or usage in such conditions. • CCD image sensors are precise optical equipment that should not be subject to mechanical shocks. 20
