(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 Cy G B Cy Mg Ye Mg Ye G Cy G Cy Mg Ye A1 Mg Ye A2 G 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). Hreg Color Coding Diagram 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)} x 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)} x 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. - 11 - ICX419AKB 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. 1. Sensitivity Set to standard imaging condition I. After selecting the electronic shutter mode with a shutter speed of 1/250s, measure the Y signal (Ys) at the center of the screen and substitute the value into the following formula. S = Ys x 250 [mV] 50 2. Saturation signal Set to standard imaging condition II. After adjusting the luminous intensity to 10 times the intensity with average value of the Y signal output, 200mV, measure the minimum value of the Y signal. 3. Smear Set to standard imaging condition II. With the lens diaphragm at F5.6 to F8, adjust the luminous intensity to 500 times the intensity with average value of the Y signal output, 200mV. When the readout clock is stopped and the charge drain is executed by the electronic shutter at the respective H blankings, measure the maximum value YSm [mV] of the Y signal output and substitute the value into the following formula. Sm = 20 x log YSm x 1 x 500 200 1 10 [dB] (1/10V method conversion value) 4. Video signal shading Set to standard imaging condition II. With the lens diaphragm at F5.6 to F8, adjust the luminous intensity so that the average value of the Y signal output is 200mV. Then measure the maximum (Ymax [mV]) and minimum (Ymin [mV]) values of the Y signal and substitute the values into the following formula. SHy = (Ymax - Ymin)/200 x 100 [%] 5. Uniformity between video signal channels Set to standard imaging condition II. Adjust the luminous intensity so that the average value of the Y signal output is 200mV, and then measure the maximum (Crmax, Cbmax [mV]) and minimum (Crmin, Cbmin [mV]) values of the R - Y and B - Y channels of the chroma signal and substitute the values into the following formula. Sr = | (Crmax - Crmin)/200 | x 100 [%] Sb = | (Cbmax - Cbmin)/200 | x 100 [%] 6. Dark signal Measure the average value of the Y signal output (Ydt [mV]) with the device ambient temperature 60C and the device in the light-obstructed state, using the horizontal idle transfer level as a reference. - 12 - ICX419AKB 7. Dark signal shading After measuring 6, measure the maximum (Ydmax [mV]) and minimum (Ydmin [mV]) values of the dark signal output and substitute the values into the following formula. Ydt = Ydmax - Ydmin [mV] 8. Flicker 1) Fy Set to standard imaging condition II. Adjust the luminous intensity so that the average value of the Y signal output is 200mV, and then measure the difference in the signal level between fields (Yf [mV]). Then substitute the value into the following formula. Fy = (Yf/200) x 100 [%] 2) Fcr, Fcb Set to standard imaging condition II. Adjust the luminous intensity so that the average value of the Y signal output is 200mV, insert an R or B filter, and then measure both the difference in the signal level between fields of the chroma signal (Cr, Cb) as well as the average value of the chroma signal output (CAr, CAb). Substitute the values into the following formula. Fci = (Ci/CAi) x 100 [%] (i = r, b) 9. Line crawls Set to standard imaging condition II. Adjust the luminous intensity so that the average value of the Y signal output is 200mV, and then insert a white subject and R, G, and B filters and measure the difference between Y signal lines for the same field (Ylw, Ylr, Ylg, Ylb [mV]). Substitute the values into the following formula. Lci = (Yli/200) x 100 [%] (i = w, r, g, b) 10. Lag Adjust the Y signal output value generated by strobe light to 200mV. After setting the strobe light so that it strobes with the following timing, measure the residual signal (Ylag). Substitute the value into the following formula. Lag = (Ylag/200) x 100 [%] FLD V1 Light Strobe light timing Y signal output 200mV Output Ylag (lag) - 13 - Drive Circuit 1 (substrate bias internal generation mode) 15V 1 2 3 XSUB XV2 XV1 XSG1 XV3 XSG2 XV4 4 5 6 7 8 9 10 22/20V CXD1267AN 20 19 18 17 16 15 14 13 12 11 0.01 1 2 3 4 5 6 7 8 3.3/20V 22/16V 1M 3.3/16V -9V 1/35V 100k 1 ICX419 (BOTTOM VIEW) VDSUB H2 H1 RG GND RD NC 10 16 15 14 13 12 11 H1 0.01 H2 100 [A] CCD OUT 0.01 RG 3.9k NC 9 VOUT - 14 - SUB VDD V4 V3 V2 V1 VL ICX419AKB Drive Circuit 2 (substrate bias external adjustment mode) 15V 0.1 1 2 3 XSUB XV2 XV1 XSG1 XV3 XSG2 XV4 4 5 6 7 8 9 10 22/20V 1 2 3 4 5 6 7 8 CXD1267AN 20 19 18 17 16 15 14 13 12 11 3.3/20V 0.01 22/16V 1M 3.3/16V -9V 1/35V 1/35V 1/35V 270k 15k 47k 56k 100k 27k 0.1 39k 15k 0.1 SUB ICX419 (BOTTOM VIEW) VDSUB H2 H1 RG GND RD NC 10 16 H1 15 14 13 12 11 0.01 H2 100 [A] CCD OUT NC 9 VOUT VDD V4 V3 V2 V1 VL - 15 - RG ICX419AKB 0.01 3.9k ICX419AKB Spectral Sensitivity Characteristics (Excludes lens characteristics and light source characteristics) 1.0 Cy 0.8 G Ye Relative Response 0.6 0.4 Mg 0.2 0 400 450 500 550 Wave Length [nm] 600 650 700 Sensor Readout Clock Timing Chart V1 V2 Odd Field V3 V4 33.6 1.5 0.2 2.5 2.6 2.5 2.5 V1 V2 Even Field V3 V4 Unit: s - 16 - Drive Timing Chart (Vertical Sync) FLD VD BLK HD 620 625 1 2 3 4 5 310 320 V1 V2 V3 V4 CCD OUT 581 582 246 135 315 325 246 135 582 581 135 246 330 135 246 335 340 10 15 20 25 - 17 - ICX419AKB Drive Timing Chart (Horizontal Sync) HD BLK H1 H2 750 752 1 745 10 20 30 40 10 20 22 1 2 3 1 2 3 10 20 3 5 1 2 3 5 - 18 - RG V1 V2 V3 V4 SUB ICX419AKB ICX419AKB 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 80C. 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 operations 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 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. For continuous using under cruel condition exceeding the normal using condition, consult our company. 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 too much mechanical shocks. - 19 - Package Outline Unit: mm 16 pin DIP (300mil) 3.29 0.3 0. 3 1.84 A B 2 3. 1 2.54 C 9 4.0 16 16 9 12.0 0.15 12.35 0.3 7.62 V 1 H 6.175 12.0 0.15 12.35 0.3 B' 1.84 1st. pin Index 1.
