HDTV Gray Scale Test Chart

HDTV Gray Scale Test Chart

The HDTV Gray Scale Test Chart
is disigned 

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 11-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 of the white field between the gray scale is D = 0.05 (reflectance = 89 %).
