    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:


    StepDensityRemission in %Output voltage in %
    10.2260100
    20.324888.75
    30.443677.5
    40.572666.25
    50.731955

    71.130732.5
    81.430421.25
    91.8501.410

    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.
