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.
