    The YE0223 is designed for evaluation of the halftone reproduction of electronic cameras. Two 13-graduated counter current gray scales are arranged on a gray background (D = 0.75), the gray scales being graduated logarithmically. Related to the densities of the gray scales: gamma = 0.45, related to the transmission values (brightness): gamma = 2.2, that being exactly the reciprocal value of gamma = 0.45. The output signal of a optimally gamma-corrected camera yields two 13-gratuated counter current linear step signals.


    The contrast range of the gray scales is 200 : 1.


    The values of the 13-graduated gray scale are as follows:

    StepDensityReflectance in %
    10.0589
    20.1374
    30.2162
    40.3050
    50.4040
    60.5131
    70.6323
    80.7817
    90.9511
    101.157
    111.414
    121.772
    132.350.5

    The density values are based on BaSo4 = 0. Two black fields and a white field are located between the gray scales, the density of the black filed is D > 2.4 (reflectance < 0.5 %). The density of the white filed is D = 0.05 (reflectance = 89.9 %).
