ISO 12233: 2014 Extended

Imatest ISO 12233: 2014 charts are implementations of the Low Contrast Edge SFR (E-SFR) test chart illustrated in Section 6.1 and Annex C of the ISO Standard Document. The Extended version is similar to the Enhanced version (extra squares, wedges, and color patterns) but with a 16:9 aspect ratio, suitable for HDTV and cinema (Note: Works with Matlab esfrChart).

The Imatest eSFR ISO module provides highly automated support for the new charts. Additional details below.

ISO 12233: 2014 Test Charts
Exceed image quality standards

Imatest charts, designed by a team of experts, were specifically developed to work seamlessly with Imatest Master, Imatest Studio and Imatest IT. Imatest test charts are the most powerful charts available for imaging system development and quality verification

Extended version:

The Imatest Extended ISO 12233:2014 E-SFR chart has all the features of the Enhanced version (six extra squares, wedges, and 16 color patches where possible), but with a 16:9 aspect ratio. That makes it suitable for HDTV and cinema measurements (and it also works well with 3:2 aspect ratio DSLRs). It is fully compliant with the standard. The Extended Version is also available with Extra Wedges..

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 with the Standard version are as follows:

  • 16:9 aspect ratio.
  • 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.

The International Standards Organization (ISO) for Photography sets the international standards for image quality analysis and all of our charts conform to the specifications set by the ISO Committee.
