]]> BOULDER, CO -September 12, 2019—Imatest, a global image quality testing solution provider is pleased to announce Imatest 5.2. With this new Imatest release, the Imatest team adds several new features to provide better analysis tools and new options.

Imatest 5.2 includes the following upgrades:

  • ON Semiconductor DevwareX support for this advanced image sensor interface software, which replaces Devware. Support for the APbase image acquisition API.

  • Decompanding for the proper processing of piecewise linear (PWL) companded RAW files, which can extend sensor dynamic range by allowing different tonal curves for ranges of digital output values.

  • Contrast Detection Probability (CDP) from Contrast Resolution chart using low-contrast path triplets to calculate the draft IEEE P2020 metric. CDP is a metric for the distinguishability from two input light levels through an imaging system.

  • Improved Color/Tone Module Interfaces—Chart selection is clearer and more robust; Color/Tone Setup is the new name for Multicharts (interactive) and Color/Tone Auto is the new name for Multitest (fixed).

  • Hyperbolic Wedge and Siemens Star analyses are now supported in Arbitrary Charts.

  • Dynamic Range (DR) Output Resistance to Flare Light—You can now detect conditions where flare light causes exaggerated DR measurements and can remedy the misleading measurements by limiting the quality-based DR to the slope-based DR, which is defined by the scene density where the patch pixel-level stops decreasing.

  • INI File Monitor produces detailed reference information about the effects of settings changes on the Imatest INI file.

  • Checkerboard Uniformity Calculations produce summaries of nonuniform illumination similar to those produced by SFRplus.

]]> Our engineers are continually adding new features and updating Imatest software to provide you with the best analysis tool on the market. In our most recent release, our team has added several new modules to provide you better analysis tools. Here are the top three new features, and why should upgrade to Imatest 5.1:

  • Compensate for chart MTF to perform accurate high-resolution or close-distance sharpness tests

MTF Compensation reduces the impact of the chart on measured imaging system MTF.

  • Geometrically calibrate single or multi-camera devices obtaining camera intrinsic and extrinsic matrices for accurate machine vision and ADAS applications

A geometrically calibrated device provides a mapping between pixel coordinates and real-world position.

  • Direct image acquisition for Sony sensors

Imatest now supports direct image acquisition from Sony sensor development boards through the Sony AYA software tool.
