This sfr test 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.
All SineImage ISO 12233:2014 E-SFR charts are fully compliant with the ISO standard. The Imatest eSFR ISO moduleprovides highly automated support for the new charts.
SineImage ISO 12233:2014 E-SFR charts are implementations of the Low Contrast Edge SFR (E-SFR) test chart illustrated in Section 6.1 and Annex Cof the ISO Standard Document. The charts come in three versions:
Standard: basic, no extra measurement features
Enhanced: extra squares, wedges, and color patterns when printed with technologies that allow color
Extended: similar to Enhanced, but with a 16:9 aspect ratio, suitable for HDTV and cinema
We currently offer these charts in inkjet format, with Enhanced versionsavailable as photographic prints. All SineImage ISO 12233:2014 E-SFR charts are fully compliant with the ISO standard. The Imatest eSFR ISO moduleprovides highly automated support for the new charts.
Remark: We support Any customized test charts only if you have high resolution image and size.
