YE0153 grayscale test chart

Sineimage YE0153 grayscale test chart (11 steps)

The YE0153 grayscale test chart is used to evaluate the halftone reproduction of an electronic camera. Two 11-stage counter-current gray levels are arranged on a gray background (D = 0.75), the gray levels are logarithmically graded

Related to gray density: γ = 0.45

And reflectance value (brightness): γ = 2.2, happens to be the inverse of γ = 0.45.

One of the best gamma-corrected camera output signals produces two 11-graduate inverse current linear step signals. The contrast ratio of the gray scale is 40: 1.

Eleven gray values are as follows:

step	density	Reflectance in%
1	0.05	89
2	0.13	74
3	0.22	60
4	0.32	48
五	0.43	37
6	0.55	28
7	0.69	20
8	0.88	13
9	1.06	8
10	1.31	五
11	1.65	2

The density value is based on BaSo4 = 0. Two black fields and one white field are located between the grayscale, with black field density D> 2.4 (reflectivity <0.5%). White density D = 0.05 (reflectance = 89.9%).

Note: We only support any custom test chart only with high-resolution images and dimensions.
