Imatest Master 25.1: The Scientific Standard for Imaging System Validation
Imatest Master 25.1 is the industry-leading software suite for the objective, quantitative analysis of digital image quality. It provides engineers, researchers, and quality assurance professionals with a comprehensive set of tools to measure and validate the performance of cameras, lenses, sensors, and entire imaging systems against international standards.
Core Function: From Test Chart to Quantitative Data
The software analyzes images of standardized test charts (like SFRplus, eSFR ISO, or Dot Pattern) to extract precise, repeatable metrics that define optical and imaging performance, replacing subjective visual assessment with scientific data.
Key Functions:
-
Resolution & Acutance: Measures MTF (Modulation Transfer Function) and SFR (Spatial Frequency Response) to quantify lens sharpness and system resolution per ISO 12233.
-
Noise & Dynamic Range: Analyzes temporal and spatial noise, signal-to-noise ratio (SNR), and dynamic range to evaluate sensor performance under various lighting conditions (ISO 15739).
-
Color & Uniformity: Tests color accuracy (Delta-E), white balance, and vignetting (lens shading) to ensure consistent color reproduction across the image field.
-
Distortion & Flaws: Quantifies geometric distortion (barrel, pincushion) and detects flaws like chromatic aberration, dead pixels, and non-uniformities.
