The Sineimage 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.
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.
