eSFR ISO 12233 2023 "Slanted Star"
eSFR ISO adds support for analyzing the 2023 “slanted star” revision of the ISO 12233 test chart
- Slanted star features double the slanted-edge measurement regions, enabling sagittal and tangential measurements from the corner of an image.
- Logarithmic wedges with improved frequency distribution.
- 18 color patches similar to the industry standard 24-patch chart.
- New test chart available: Inkjet, Lightboxes, High-precision Film.
Additional linearization options for eSFR ISO & SFRplus
Including the ability to linearize using the inverse of the OECF measured from the grayscale step chart patches. This can improve the accuracy of MTF measurements with systems that have nonlinear tonal response or when using higher contrast targets.
Dynamic Range Postprocessor
- Produces results similar to IEEE P2020 (draft) noise standard. Described in A review of IEEE P2020 noise metrics
- Now supports sensor dynamic range calculations from multi-image exposures from HDR sensors.
Stray Light
- Supports the IEEE-P2020 pre-release flare attenuation calculation. Our next-generation light source, scheduled for late 2023/early 2024, will meet the uniformity requirements for accurate calculation of flare attenuation. Imatest recommends P2020 (draft) normalized stray light calculation with our current Stray Light LED Light Source.
- Ability to normalize with a reference image of a Lambertian diffuser.
- Ability to choose output data transforms including linear, logarithmic, and decibel.
- Ability to subtract off a dark level.
- Ability to have level count summary metrics expressed as a percentage.
- Ability to select an analysis channel including: RGB, Each Channel, Mean, and Luminance.
- Improved visualization of masked pixels in colormapped metric images.
- Now includes the minimum measurable stray light in results.
Other Features
- Arbitrary Charts: Includes CIELAB 94 ΔH and CIELAB 2000 ΔH to Arbitrary Charts color analysis.
- Installer: significantly reduced installer and installation size.
- MacOS 14 Sonoma Support
Main Window Improvements
- New License Manager to administer your Imatest license. Activate, deactivate, and more.
- Includes the ability to view the first frame of video files in Image Preview.
- Includes General Settings performance improvements.
