Product Description

SineImage Cheap Professional Two 9-graduated Counter Current Gray Scales COLOR CAMERA GRAY SCALE TEST CHART

 

 

Two 9-graduated counter current gray scales are arranged on a gray background (D ≈ 0.75), the gray scales being graduated logarithmically (gamma = 0.45). The output of an optimally gamma-corrected camera yields two 9-graduated counter current linear step signals. The contrast range of the gray scales is 50:1.

 

The values of the 9-graduated gray scale are as follows:

 

Step Density Remission in % Output voltage in %
1 0.22 60 100
2 0.32 48 88.75
3 0.44 36 77.5
4 0.57 26 66.25
5 0.73 19 55
6 0.91 12 43.75
7 1.13 07 32.5
8 1.43 04 21.25
9 1.85 01.4 10

 

 

The density values are based on a density of BaO4S= 0.

 

The test chart incorporates a super black cavity for the accurate adjustment of camera flare corrections and setting of black level. On both sides of the super black hole 4.5 and 5.5MHz bars with a contrast ratio of 7:1 are located. Above and below the gray scales there are additional markings for the 16:9 format.
