HDTV Log. Gray Scale Test Chart, 13 steps, contrast 1:200 YE0223 Halftone Reproduction Evaluation Chart
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:
| Step | Density | Reflectance in % |
| 1 | 0.05 | 89 |
| 2 | 0.13 | 74 |
| 3 | 0.21 | 62 |
| 4 | 0.30 | 50 |
| 5 | 0.40 | 40 |
| 6 | 0.51 | 31 |
| 7 | 0.63 | 23 |
| 8 | 0.78 | 17 |
| 9 | 0.95 | 11 |
| 10 | 1.15 | 7 |
| 11 | 1.41 | 4 |
| 12 | 1.77 | 2 |
| 13 | 2.35 | 0.5 |
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 %).
