Apple Silicon Support

Previously, Apple Silicon Macs were supported through the Rosetta 2 emulation layer, which slowed down performance.  Now, we offer a MacOS silicon build with improved performance.

Simatest Camera & ISP Simulator

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 Improvements

  • Open With Imatest: Open files directly from Windows Explorer and MacOS Finder into Imatest Master.
  • New direct links to the Imatest Store for most analysis targets to easily view Imatest’s chart offerings.
  • Improved Console Panel layout with docking and full-screen options.
  • New UI Settings page to easily manage user interface preferences.
  • Imatest Master now respects operating system-preferred applications when opening files and images.
