    Standard Version

    Standard Version

    This chart, which has a 3:2 aspect ratio, is a "no-frills" implementation of the standard. For most work we recommend the Enhanced or Extended charts, which have additional edges for measuring performance near the image boundaries, as well as hyperbolic wedges and color patches (where the technology allows). These chartsmaintain full compliance with the standard.

    The Imatest Standard ISO 12233:2014 E-SFR chart closely resembles the Low contrast E-SFR test chart illustrated in section 6.1 and Annex C of the ISO standard document, with a few differences, all of which are fully compliant with the ISO standard.

    • A 20 patch OECF grayscale pattern* is used instead of the 16 patch version.
    • The Focus Patterns in the centers of the squares are rectangular (to increase the MTF measurement area) and are designed to reduce interference with automatic edge detection.
    • There are four registration marks instead of three to facilitate automated region detection. (Four features are required for a projective transform.)
    • An additional mark above the lower-left registration mark is used for detecting chart orientation.

    Enhanced Version

    Enhanced Version

    The Imatest Enhanced ISO 12233:2014 E-SFR chart has all the features of the Standard chart, keeping the 3:2 aspect ratio, with the addition of six added slanted squaresfor measuring performance near the image boundaries and hyperbolic wedges for visual analysis or analysis with the Imatest Wedge module. It also has 16 color patches when produced with technologies that allow color. Since these additions are in regions of the chart not covered by the standard, compliance with the standard is unaffected.

    The differences between the Imatest charts and the chart illustrated in the standard are listed below. Even with these differences the Imatest chart is in full compliance with the standard.

    • A 20 patch OECF grayscale pattern* is used as opposed to the 16 patch version.
    • The Focus Patterns in the centers of the squares are rectangular (to increase the MTF measurement area) and are designed to reduce interference with automatic edge detection.
    • There are four registration marks instead of three to facilitate automated region detection. (Four features are required for a projective transform.)
    • An additional mark above the lower-left registration mark is used for detecting chart orientation.

    The differences between the Enhanced and Standard Versions are as follows:

    • Six extra slanted squares are added for measuring performance near the image boundaries.
    • Several hyperbolic wedges with spatial frequencies, similar to the CIPA chart referenced in the ISO standard, for visual analysis or use with the Imatest Wedge module.
    • 16 color patches when produced with technologies that allow color (inkjet or color LVT), with colors similar to the industry-standard 24-color test chart.

    This chart will work with the fully-automated eSFR ISO module.

    The values of the 11-graduated gray scale are as follows:

     

    Step Density Reflectance in %
    1 0.05 89
    2 0.13 74
    3 0.22 60
    4 0.32 48
    5 0.43 37
    6 0.55 28
    7 0.69 20
    8 0.88 13
    9 1.06 8
    10 1.31 5
    11 1.65 2

     

    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 %).
