Calculate the maximum value δ Ymax, δ Rmax, δ Gmax and
δ Bmax of the measurement point (gray scale: 22 patches).
・ Minimum ISO sensitivity
δ Ymax ≦ 3.5
δ Rmax 、δ Gmax 、δ Bmax ≦ 4.0
・ISO200 δ Ymax ≦ 5.5
δ Rmax ≦ 6.0 、δ Gmax ≦ 5.5 、δ Bmax ≦ 6.0

（Correct exposure to obtain "220 (8 bits)" in the case of "White
100%".）
(Equip the 5100K viewer with a scale and shoot an object in the
full range of angle of view.)
（Perform defocusing not to generate reticulate moires.）
（Calculate the standard deviation δ Y, δ R, δ G and δ B of
Y, R, G and B for the central area 64 pixels × 64 pixels of each
density.）
