YE0153 gray scale resolution test chart (11 steps) grey chart with 11 patches 4:3
Sineimage YE0153 Gray Scale Test Chart(11 steps) Grey Chart with 11 Patches 4:3The YE0153 is designed for evaluation of the halftone reproduction of electronic cameras. Two 11-graduated counter current gray scales are arranged on a gray background (D=0.75), the gray scale being graduated logarithmically. Related to the densities of the gray scales: gamma = 0.45 Related to the reflectance values (brightness): gamma = 2.2 , that being exactly the reciprocal value of gamma = 0.45. The output signal of an optimally gamma-corrected camera yield two 11-graduates counter current linear step signals. The contrast range of the gray scales is 40 : 1. The values of the 11-graduated gray scale are as follows:
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 %). |
