Color coding of this image sensor & Composition of luminance (Y) and chroma (color difference) signals Cy Ye Cy Ye G Mg G Mg Cy Ye Cy Ye A1 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 A2 the horizontal shift register (Hreg) is, for line A1, (G + Cy), (Mg + Ye), (G + Cy), and (Mg + Ye). B Mg G Mg G 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. - 10 - ICX278AK 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. Sensitivity Set to standard imaging condition I.

S = Ys x 250 [mV] 60 2. Sensitivity ratio 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 Mg signal output (SMg [mV]) and G signal output (SG [mV]), and Ye signal output (SYe [mV]) and Cy signal output (SCy [mV]) at the center of the screen with frame readout method. Substitute the values into the following formula. RMgG = SMg/SG RYeCy = SYe/SCy 3. 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. 4. 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) - 11 - ICX278AK 5. 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 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 [%] 6. 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 [%] 7. 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. 8. Dark signal shading After measuring 7, measure the maximum (Ydmax [mV]) and minimum (Ydmin [mV]) values of the Y signal output and substitute the values into the following formula. Ydt = Ydmax - Ydmin [mV] 9. 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) - 12 - ICX278AK 10. 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) 11. 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.

Torsional strength strength - 18 - ICX278AK 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. 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, 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 poweroff 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. d) This package has 2 kinds of internal structure. However, their package outline, optical size, and strength are the same.
