ISO 12233 eSFR Charts for Imatest LED Light Sources
The ISO12233:2017 eSFR Test Charts are available Pre-Mounted for use with Imatest LED Light Sources. This chart is designed to work with the eSFR ISO Module.
Imatest ISO 12233:2017 eSFR Test Charts are implementations of the Low Contrast Edge SFR (eSFR) test chart illustrated in Section 6.1 and Annex C of the ISO Standard Document. The chart is available in two general versions:
- 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 (Note: Works with Matlab esfrChart)
