Major Version:

May 15, 2025

New Features:

  • Simatest enables the simulation of camera systems including image sensor noise & signal processing. This enables convenient exploration of how ISP parameters impact Image quality metrics. See Example, Brochure & Documentation. Includes Image Sensor Noise Model analysis. The model estimates temporal and fixed pattern noise from a single Bayer RAW image for color/tone noise analysis, using a three-component model (dark, shot, and fixed pattern noise).

  • User Interface Improvement: Open With Imatest: Open files directly from Windows Explorer and MacOS Finder into Imatest Master.

  • User Interface Improvement: New direct links to the Imatest Store for most analysis targets to easily view Imatest’s chart offerings.

  • User Interface Improvement: Improved Console Panel layout with docking and full-screen options.
  • User Interface Improvement: New UI Settings page to easily manage user interface preferences.
  • User Interface Improvement: Imatest Master now respects operating system-preferred applications when opening files and images.
  • User Interface Improvement: Improved Image Preview with the ability to navigate to another image using the left and right navigation buttons without leaving image preview.
  • Preliminary Documentation of Outputs: New web page and Excel sheets documenting JSON outputs for distortion and sharpness measurements.
  • Settings Improvement: The Settings page has been reorganized with easier access to Imatest Master analysis settings, a new “Save + Re-Analyze” button, performance improvements, and a better search experience.
  • Settings Improvement: IT and Pass Fail Settings can now be edited using the new Settings Window.
  • Concentric Rings FOV: Measure optical distortion: New Plot and output for Optical Distortion %
  • Concentric Rings FOV: Regmark detection default is now ML/CV
  • Concentric Rings FOV: Documentation of results.
  • Stray Light: Ability to extract select metadata from a filename via regular expression.
  • Stray Light: Support for custom RGB Luminance weights.
  • Stray Light: Ability to calculate the IEEE Std. P2020 Flare Method B mask radius.
  • Stray Light: Additional tuning options for image processing based masking.
  • Stray Light: Documentation of results.
  • Batchview: Allow multiple parameters plots to be combined into single plots.
  • Batchview: Addition of information metrics C_4, C_max, SNRi for 2×8 pixel object, edge location standard deviation (sigma).
  • Batchview: Option to plot vertical axis logarithmically.
  • Batchview: Improved automatic scaling, global & local scaling, manual scaling.
  • Batchview: Plot from zero-max or min-max.
  • Checkerboard: Ability to limit Distortion measurements to the image circle.
  • Checkerboard: includes information on the extrapolation region for distortion measurements.
  • Color/Tone: eSFR ISO Color now has automatic detection and ROI placement.
  • Color/Tone: Rezchecker default reference file has been updated from glossy to matte. The previous default reference file can be downloaded for Matte and Glossy targets.
  • New Luminance Settings: for ITU-R BT.601-7, ITU-R BT.709-6/IEC 61966-2-1, ITU-R BT.2020-2, or user specified in stray light.
  • Sharpness Modules: Now include option to include edge spread function (ESF) and line spread function (LSF) data in JSON results.
  • Sharpness Modules: Interpolated SFR data has been added to Multi-region CSV summary file results.
  • Rescharts/colortone/flatfield modules: have Updated default save files from “CSV summary file” to “Multi-region CSV summary file” and “JSON Summary file”.

Known Issues:

  • MacOS builds are not yet notarized. This is the current workaround:
    • System Preferences. Security & Privacy.
    • Under the General tab, click Open Anyway for Imatest Master.
    • Select Open. Proceed with the installation from here
  • Linux mp4 file read/write does not work

Minor Versions:

v25.1.2 June 26, 2025

  • Resolved a crash in Simatest that occurred when analyzing a batch of images.
  • Resolved issues that were preventing Flatfield hot/dead pixel settings and calculations from working with some images that have nonstandard bit depth.
  • Fixes saving of images with ROI overlays in Auto (batch) Rescharts modules.
  • Added SNR_BW (dB RGBY) label to the ColorTone noise plot.
  • Resolved an issue where stray light pixel count metrics were incorrectly rounded to the nearest integer when “Count Type” was set to “Percent of Pixels”.
  • Fixed a crash in Color/Tone that could occur for certain noise plots with lux selected as the x-axis unit.
  • Fixed a crash that could occur after editing certain Color/Tone settings from the interactive results window after an initial analysis was run.

v25.1.1 June 02, 2025

  • Corrected SFRplus Secondary Readout Calculation for “LR” quadrant
  • SFRPlus- Suppresses stray printing of a filename
  • GamutVision- Fixes issues launching on macOS and linux
